The wool was then lifted out and drained, after which it was rinsed in a current of clean water to remove the " scour " and then dried . These operations are now performed in scouring

See also:average wool will be in the scouring liquor about eight minutes, the temperature will vary from 120° F. to 1Io° F., and the length of bath through which it will have passed will be from 48 to 6o ft .
It is interesting tonote that the " emulsion " method of wool scouring as described above is practically universal in England . In the
See also:United States of
See also:America the " solvent " method is largely in use, for the two points aimed at are quantity of production and cheapness . Quality is sacrificed to quantity and cheapness results from the ease with which the agent employed—say carbon disulphide —is recovered by volatilizing and condensing, thus being used over and over again . Botany wools should leave the wool-washing machine in a fit condition to be fed immediately on to the carder, provided that the first cylinders are clothed with galvanized wire . Cross-bred and English wool, however, require artificially drying . The more gently and uniformly the drying can be effected the better is the result attained; over-drying of wool has to be specially guarded against . By some manufacturers the wool from wool the squeezing rollers is whizzed in a hydro-extractor, drying. which drives out so much of the moisture that the further drying is easily effected . The commonest way, however, of drying is to spread the wool as uniformly as possible over a framework of wire netting, under or over which is a range of steam-heated pipes . A
See also:fan blast blows air over these hot pipes, and the heated air passes up and is forced upwards through the layer of wool which rests on the netting or downwards, as the case may be . In this case, unless the wool is spread with great evenness, it gets unequally dried, and at points where the hot air escapes freely it may be much over-dried . A more rapid and uniform result may be obtained by the use of the mechanical wool drier, a close chamber divided into
See also:horizontal compartments, the floors of which have alternate fixed and movable bars . Under the chamber is a tubular
See also:heating apparatus, and a fan by which a powerful current of heated air is blown up the side of the chamber, and through all the shelves or compartments successively, either following or opposing the wool in its passage through the machine .
The wool is introduced by a continuous feed at one side of the chamber; the strength of the blast carries it up and deposits it on the upper shelf, and by the action of the movable bars, which are worked by cranks, it is carried forward to the opposite end, whence it drops to the next lower shelf, and so on it travels till at the extremity of the lower shelf it passes out by the delivery lattice well and equally dried . Another drying machine in extensive use is what is known as the " Jumbo Dryer." This consists of a large revolvingcylinder or
See also:churn which turns over the wool—as a churn turns butter—and owing to its inclination passes it from one end to the other . A hot air blast follows the wool through the machine . In this and in all drying machines it is more important to get the moisture laden air away from the wool than to develop a great heat . The dried wool may be in a partially matted condition . If so, it must be opened out and the whole material brought into a uniformly free and loose condition . This effected in the Willey, Teasing. which consists of a large
See also:drum and three small cylinders mounted in an enclosed frame . The drum is armed with ranges of powerful hooked teeth or spikes, and is geared to rotate with great rapidity, making about 500 revolutions per minute . The smaller cylinders, called workers, are also provided with strong spikes; they are mounted over the drum and revolve more slowly in a direction contrary to the drum, the spikes of which just clear those of the workers . The wool is fed into the drum, which carries it

For certain classes of wool, notably Buenos Aires, still another preparing operation is essential at this stage—that is, the removal of burrs or small persistently adherent seeds and other Burring. fragments of vegetable matter which remain in the wool . Two methods of effecting this—one chemical, the other mechanical—may be pursued . The chemical treatment consists in steeping the wool in a dilute solution of sulphuricacid (or other carbonizing agent), draining off the dilute acid by means of the hydro extractor, and then heat-drying in a temperature of about 25o° F . The acid leaves the wool practically uninjured, but is concentrated on the more absorbent vegetable matter, and the high heat causes it to
See also:act so that the vegetable matter becomes completely carbonized . The burrs are then crushed and the wool washed in water rendered sufficiently alkaline to neutralize any free acid which may remain, and dried . The same
See also:burr-removing effect is obtained by the use of a solution of chloride of aluminium, a method said to be safer for the wool and less hurtful to the attendant workmen than is the sulphuric acid process . For mechanical removing of burrs, a machine some-thing like the Willey in appearance is employed . The
See also:main feature of this apparatus is a large drum or swift armed with fine short spikes curved slightly in the direction in which it rotates . By a series of beaters and circular brushes the wool is carried to and fed oh these short spikes, and in its rotation the burrs, owing to their weight, hang out from the swift .

The swift then throws its brushed-uk coating of wool into the slowly retreating teeth of the doffer H, which carries it forward until angle stripper C' strips the doffer, to be in its turn stripped by swift D' and soon . The speeds of the cylinders are in the first place obviously dependent upon the principle of carding adopted, the greater speed always stripping (save in the case of the fancy) . As to whether the speed shall be obtained by actual revolutions or by a larger diameter of cylinder depends upon the nature of the wool to be carded (long or short), the part which each cylinder has to
See also:play in the card, and upon the question of
See also:wear of clothing and power consumed . As a rule the strippers are all driven from a smaller circumference of the swift to obtain conveniently the necessary reduction in speed, and the slowly revolving workers are chain driven from the doffer, which indirectly receives its motion from the swift . The principles involved In the relative inclinations of teeth are very apparent, but the principles involved in the relative densities of teeth on the respective cylinders are again much involved and little understood . A complete scribbler or first card engine consists of a
See also:breast, or small swift, and two swifts with the accompanying workers, strippers, fancies, doffers, &c . The wool is stripped from this card as a thin film by means of the doffing
See also:comb . This is usually weighed on to the next machine—whether intermediate or condenser—a given weight giving a definite count of condensed sliver . Should an intermediate be employed, there must be an automatic feed, taking the wool, as stripped from the last doffer of the intermediate, and feeding it perfectly evenly on to the feed sheet of the condenser .
The con-denser is usually a one-swifted card, the only difference in principle being that, whereas the sliver comes out of the scribbler or inter-mediate in one broad film, it is broken up into a number of small continuous slivers or films, each one of which will ultimately be drafted or

There are many forms of condensing mechanisms such as the single-doffer, the doubledoffer and the tape-condensers, but their construction is too complex to be described here . Whatever the type may be, the result is that noted above, but it should be noted that the tape enables a much finer sliver to be taken from the card than is possible with either the single- or

See also:carriage), and the carriage EE carrying the spindles which may be run close up to the front de-livery rollers and about two yards away from them to effect the " spin, " which is of an intermittent character . The spindles D are turned by bands passing round a tin drum K in the carriage, but this motion, and every other motion in the mule, is controlled perfectly from the headstock . In brief, the operation of spinning is as follows: as the carriage begins to recede from the delivery rollers these rollers deliver condensed sliver at about the same rate as the carriage moves out, the spindles putting in a little twist .
When the carriage has perhaps completed half its

See also:carpet and knitting yarns, which are treated in a much readier manner than any of the foregoing, but as the treatment is analogous—with the elimination of certain processes—to the second of the foregoing, it is not necessary to refer specially to it . To obtain a sliver or " roving " which can be satisfactorily spun into a typical worsted thread the following operations are necessary :—preparing (five or six operations), back-washing, straightening, combing, straightening and drawing (say six operations), and finally spinning on the flyer frame . After long wool has been scoured and dried it is necessarily considerably entangled, and if it were to preparing be combed straight away a large propor- tion of the long fibres would be broken and combed out as " noil " or short fibre . To obviate this the wool is fed as straight as possible into a sheeter gill-box; after this it passes through other two sheeter gill-boxes, then through say three can gill-boxes . As shown in fig. to the main features of a preparing or gill-box are the following: the feed sheet upon which the wool is " made up," the back rollers B which take hold of the wool and deliver it to the fallers F which, working away from the back rollers more quickly than the wool is delivered, comb it out . The fallers in turn deliver the wool to the front rollers D, which, 'taking in the wool more quickly than the fallers delivering it, again draft and comb it, but with a reversing of the former combing operation . The wool emerges from the front rollers as thin attenuated continuous fibre about 12 in. wide, which is wound upon an endless
See also:leather sheet H from which the box takes its name . When a sliver of sufficient thickness has been wound upon the sheet, it is broken across and fed up at the next gill-box .
The fourth gill-box delivers into cans instead of on to a sheet . A number of cans are then placed behind the fifth box and the slivers from these fed up into the back rollers, and similarly with the
See also:sixth . The
See also:primary object of " preparing " or Billing is to straighten and parallelize the fibres in the sliver . This is effected by means of the combining or doubling and drafting to which the slivers are subjected . In addition to this, how-ever, a level sliver suitable for combing is formed by the combined action of the drafting and doubling which has taken place at each box . Oil will have been added to the wool at the first preparing-box to cause the fibres to work well . Back- Were this all, there would perhaps not washing, be the necessity for back-washing . But the slivers during their passage through the preparing-boxes become sullied naturally, and in addition, owing to the opening out of the locks of wool, dirt which was not " got at " in the scouring now works out and further sullies the slivers . It is consequently necessary to 1 of two scouring tanks with immersing rollers, drying cylinders, a gill-box and oiling motion .

Their condition may be further improved by passing them through one or two more gill-boxes, prior to combing, to ensure straightness of fibre and evendistribution of the lubricant . Prior to the mechanical era wool was combed immediately after scouring; there was no preparatory process . As a matter of fact the first combing process took the place of the processes Combiug. just described and was termed "straightening," the " combing proper " following . Prior to the invention of a really satisfactory mechanical comb, between 185o and 186o, the combing operation was the

See also:Lord Masham) was made a truly
See also:practical success about the year 185o . Latter-day combs of this type may be readily grouped under three heads .
The Lister or " nip " comb is specially suitable for long wools and mohair and alpaca . TheHolden or square-motion comb is specially suited for short and very good quality wools . The last type, the Noble, is the most popular of all and, by a
See also:change of large'and small circles, may be adapted to the combing of long, medium or short wools . As the great bulk of cross- bred and a considerable proportion of botany wool is combed upon the Noble comb a brief description is here called for . The object of all wool combing is to straighten the long fibres and to comb out from the slivers treated all the fibres under a certain length, leaving the long fibres or " top " to form the sliver which is eventually spun into the worsted yarn . The Noble comb, which so effectually accom- plishes this, consists in the main of a large revolving circle A inside which revolve two smaller circles B, B' as shown in fig . 12, each of which touches the larger comb circle at one point only . At this point the slivers of wool to be carded are firmly dabbed into the pins of both the large and small circles . As the circles continue to revolve A, A' are the back-rollers in a drawing box of which A is positively driven and A' driven by
See also:friction which may be varied at will .
See also:Carriers B, B', B" simply
See also:control the fibres of which the sliver is composed during drafting . The front rollers C, C'—of which C is positively driven and C' driven by friction—running at a greater speed than A, A' draft or elongate the slivers as required: The carriers B, B', B" should be speeded to run at a suitable rate to assist the drafting operation, more by support than by
See also:direct aid . Rollers A, A' must hold the sliver, hence they are fluted .
Rollers C, C' must pull the sliver somewhat severely, hence roller C' is covered with leather . The yarn delivered by the front rollers is slightly twisted and wound into a double-headed bobbin of convenient size on the " flyer-system." they naturally begin to separate, combing the wool fibres between them, the short fibres or " noil " being retained in the teeth of both small and large circles, the long fibres
See also:hanging on the inside of the large circle and on the outside of the small circle . A stroker or air blast at F now directs these long fibres into the vertical rollers, G and G', shown here in plan, which draw them out, thus separating them from the short fibres . There are at least four pairs of drawing-off rollers in a comb, and the fibres drawn off by each—be it noted continuously—are united to form a sliver which is passed through a revolving
See also:funnel into a can . The short fibres, or " noil," are lifted out of the pins of the small circle by "noil knives." The continuous slivers, the ends of which remain in the pins of the large circle after the drawing-off rollers have been passed, are now lifted up until these ends are above the pins, at the same time an additional length of sliver being drawn into the comb, so that, as they reach the second small circle, they are ready to be again dabbed into the pins of both circles and the combing operation repeated . Thus the combing on a Noble comb is absolutely continuous . All the movements of this machine—with the exception of the dabbing-
See also:brush motion—are circular, so that mechanically it is an almost perfect machine . As illustrating the extent of the combing industry, it is interesting to note that even the making of dabbing-brushes is a separate and by no means unimportant trade . After combing it is usual to pass the " top " through two gill-boxes termed " finishers." The last of these boxes, and often the first, delivers the " top " in the form of a
See also:ball, thus it is often spoken of as a " balling gill-box." This stage marks one of the great divisions of the worsted trade, the comber taking the wool up to this point, but now handing it forward in the shape of top to the " worsted spinner," who draws and spins the slivers into the most desirable worsted yarns . English tops are usually prepared for spinning by seven or eight operations . Three of these operations are effected in gill-boxes of a somewhat similar type to the preparing-box, only lighter Drawing. in build . The remaining four are drawing-boxes, i.e. as shown in

13 and 14, they consist of back and front rollers with small carrying-rollers—not gills—to support the wool in between . Thus an English set of drawing usually consists of a single-can gill-box, a double-can gill-box, a two-spindle gill-box, a four-spindle drawing-box, a four-spindle weigh-box, a six-spindle drawing-box, two six-spindle finishers and three
See also:thirty-spindle rovers . About fifteen flyer frames of 16o spindles each will be required to follow this set, although the
See also:balance varies partly in accordance with the counts spun to, in this case 1/32's English being the standard . The object of drawing is to obtain firstly a level sliver from which an even thread may be spun, and secondly to reduce the comparatively thick top down to a relatively thin roving from which the required count of yarn may be spun . Of course
See also:parallelism of fibres must be retained throughout, so far as possible . To accomplish these
See also:objects doubling and drafting is resorted to . Thus the ends put up at the back of the above boxes will be 6, 6, 4, 4, 3, 3, 2 respectively, while the drafts may be 5, 6, 8, 8, 6, 9, 9 approximately . As the drafts markedly preponderate over the doublings, so in exactly this proportion will the sliver be reduced in thickness . The flyer spinning frame is very similar to the drawing frame, consisting of back rollers, carriers and front rollers, with the necessary Sp?nning. spindle and flyer to put twist into the yarn and to wind it upon the bobbin . From the two-spindle gill-box to the spinning frame the spindle, bobbin and flyer combination is em- ployed with the object just mentioned . From fig . 15 the action of this combination will be clearly understood .
Drafting takes place as usual between the back and front rollers, the carriers controlling the yarn between the two . On emerging from the front rollers the yarn usually passes through an eyelet, to centre it over the centre of the spindle; it then takes a turn or two round the flyer
See also:leg, through the twizzle or eyelet on the flyer and on to the bobbin F . The flyer may be freely rotated by means of the wharl J and through the spindle G upon the top of which it is screwed . The bobbin fits loosely over the spindle and rests upon the lifter

See also:plane of delivery of the yarn, i.e. the eyelet of the revolving flyer . Now, if for one moment it be considered that the bobbin may not revolve on the spindle but may be the operation of carding . On first thought it might be imagined that carding would result in broken fibres and a poor yield of top . That this is not so is evident from the fact that there carding of is a tendency to card wools from 7 to to in. long, this medium tendency being due to the relative cheapness of carding m d short as compared with preparing . If long wools were fed directly wools for on to a swift, no doubt serious breakage of fibre would worsted occur, but it is customary to place before the first swift yarns. of a worsted card a series of four opening rollers and dividers—with their accompanying " burring rollers "—to open out the wool gradually, so that when it eventually reaches the first swift it is so opened out that further opening out instead of breakage occurs . Some carders use a breast or small swift in place of those opening rollers—mostly on account of
See also:economy . The swift is usually surmounted with four workers and strippers and is very similar to the woollen carder, save that the workers and doff er are larger, thereby effecting more of a combing action and working economically by reason of the greater wearing surface brought into play . As botany wool is usually brought directly from the wash bowl to the feed sheet of the card, it is usual to clothe the first cylinders with galvanized wire clothing . After the carding the wool is back-washed and gilled—on similar lines to English wool—and then is ready for combing .
The largest combers of botany wools, MessrsIsaac Holden & Co., Combing employ the square-motion comb, in fact this comb is em known in the trade as the Holden comb . Other combers, amnd fldivan however, almost without exception employ the Noble wools. comb with a fine " set over," i.e. fine spinning of the comb circles After combing, the tops are "'finished " by being passed Flyer Spindle .

Wools not more than 7 in. long are usually prepared for combing by Following the lead of the cotton trade endeavours have been made to positively control the driving and speed of both flyer and bobbin in all the drawing frames of such sets as that described above . Such control is usually effected by a pair of cones, from which this system has taken its name, viz . " cone " drawing . In fig . 16 a usual type of cone drawing-box is illustrated . The chief advantages of this system seem to be the possibilities of employing larger bobbins, and thus obtaining greater production, the
See also:consumption of relatively less power, and more particularly the production of a softer sliver with less twist, partaking more of the character of a French roving . Spinning is usually effected upon the cap frame (see fig .
17)—a frame in which the bobbin, resting upon a fixed spindle, is itself driven at say 5000 revolutions per minute to put in the twist, while the friction of the yarn on the cap which covers the bobbin enables the bobbin to wind up upon itself the yarn as delivered by the front rollers . The weakness and the strength of the cap frame is that to make reasonably hard bobbins the bobbins must be driven at a high speed . The French are noted for a special system of worsted spinning, which, pro-French • ducing soft botany yarns of a drawing marked type, is worthy of and more than passing comment. spinning . The preparation is very similar to the preparation of botany yarns for the English system save that as a rule the
See also:order of the operations are carding, gilling, combing, back-washing and finishing . The characteristic features of the method lie in the subsequent drawing and spinning . The drawing-box as shown in fig . 18 consists of back rollers, porcupine or revolving gill, front rollers, rubbers and winding-up arrangement . Thus there is no twist inserted, the slivers being treated softly and openly right away through the processes . A set of this type usually consists of two gill-boxes preparing for combing, comb, back-washing machine and two finishing gill-boxes, first drawing frame, second drawing frame, the slubbing frame, the roving frame and the self-acting mule . After leaving the last box as a fine soft pith-like sliver, spinning is effected upon the worsted mule . The main differences between the worsted and the woollen mule are firstly, the worsted mule is fitted with preliminary drafting rollers, and secondly, there is little or no spindle draft . As the mule is an intermittent worker it is natural to contrast it with the cap frame, which runs continuously .
What the real advantage is it is difficult to say, but the mule-spun worsted yarn trade is becoming yearly of more importance, and it is pleasing to note that English spinners are at last doing a fair

Again the fashion some- times runs upon fancy twists, and then it is necessary to be able to produce the various styles of
See also:loop, curl, knop, &c., yarns . Twofolding is done upon the flyer, cap and ring frames . The main difference between the cap and the ring frame is that in the latter a small bent piece of wire, termed a traveller, revolved round a ring by the pull of the spindle through the yarn, serves as the retarder to enable the bobbin to wind the yarn, delivered by the front rollers on to itself (see fig . 19) .

The operation of scouring is effected in a " dolly," and must thoroughly clear the piece so that it is free to take the woollen desired finish . The piece is now soaped and " milled," i.e. cloth felted . Milling may be effected either in the

The raising as a rule is cloth effected by brushing, although it is by no means unfinishing. common to raise worsteds on the gig . Cropping, crabbing, pressing and steaming are the same as for woollen fabrics . Of course the real difference between the woollen and the worsted cloth is due to the selection of the right material, to correct roving, spinning and fabric structure: finishing simply comes as a " developer " in the case of the woollen fabric, while in the case of the typical worsted fabric it simply serves as a " clearer," the cloth really being made in the loom . A woollen cloth as it leaves the loom is unsightly and in a sense may be said to be made in the finishing, although it is truer to say " developed " in the finishing: in the case of the worsted cloth it is altogether otherwise . A cotton warp, lustre weft
See also:style, is treated altogether differently from either of the foregoing . It is first crabbed, then steamed, then Lustre scoured and dried, then singed by being passed over a finishing. red-hot copper plate or through

Thus,for instance, the finishing of an "
See also:Italian " may be considerably varied from the foregoing, being more complex, while other styles, such as plain all-wool goods, are treated very simply . It will be gathered from the foregoing remarks that the varieties of wool textures are many and very different in character .

None theeless mohair texture remarkable and weighing say 2-3 3 oz. per Y worsteds. is the difference in appearance of varieties of wool textures . A rough
See also:tweed, for example, contrasts strangely with a smooth fine wool Italian . Of course these differences are not created in any one process or merely by the selection of the raw material or yarn . Every process of manufacture must be directed to attain the desired end, and it is well to realize that huge businesses have been built up upon what, by the outsider, would only be regarded as unimportant details . The
See also:principal styles of woollen cloth are tweeds, meltons, Venetians, beavers, doeskins, buckskins, cassimeres and diagonals . The largest class is the tweed, as this ranges from very expensive coatings and trouserings to the cheap styles made of the re-manufactured materials . Tweeds for ladies' wear also form a large class . The principal styles of worsted cloths are coatings and trouserings, delaines, voiles, merinos, cashmeres, lastings, crepe-de-chines,
See also:Orleans, lustres of various types (plain and figured), alpacas, Italians, moreens, &c., &c . Many of these are made entirely of worsted yarns, but others are compound so far as material or yarn is concerned .

With the remarkable colonial developments of the 17th, 18th and 19th centuries, in conjunction with the invention of the spinning frame and power-loom, this expectation was most fully realized, at least so far as ordinary wearing fabrics were concerned . Latterly, however, with the development of skill in newly developed countries, the tendency has been to partially revert to the old conditions . Thus in 185o Bradford's chief export was cloth, in 1875 the yarn trade had markedly developed, in 1900 the top trade was well established, and to-day Bradford has a large wool export trade . Fabrics are made for the home and general export trade; yarns are exported mostly to the continent; tops and wool mostly to the United States of America . The following tables give a useful idea of (a) the

Prior to the development of the factory system and the remarkable development in textile appliances at the end of the 18th and beginning of the 19th centuries, the textile industries were scattered attires of all over the country, only in some few cases more or less industry . accidental centralizing occurring . To-day it may be said that the wool industry is centralized where the

Since about 1856, however, there can be no doubt that the English wool trade has been centring snore and more round Bradford, while the remanufactured materials and the blanket trade is centred round Batley and Dewsbury .

Specialization undoubtedly favours Bradford, as there the wool, top, yarn and fabric branches of the industry are individually developed to great advantage; but the development of means of communication and some such factor as electric or water power may radically disturb the present balance of the industry .
