BAGGING  , the name given to the textile stuff used for making bags (see also SACKING and

TARPAULIN) . The material- used was originally Baltic hemp, while, in the beginning of the 19th century Sunn hemp or India hemp was also employed . Modern requirements call for so many different types of bagging that it is not surprising to find all kinds of fibres used for this purpose . Most bagging is now made from yarns of the jute fibre . The cloth is, in general, woven with the plain weave, and the warp threads run in pairs, but large quantities of bags are made from cloths with single warp threads . In both cases the weave used for the cloth is that shown at A in the figure, but when double threads of warp are used, the arrangement is equivalent to the weave shown at B . The interlacings of the two sets of warp and weft for single and double warp are 0 < shown respectively at C and D, the black marks indicating the warp threads, and the white or blanks showing the weft . The particular style of bagging depends, naturally, upon the kind of material it is intended to hold . The coarsest type of bagging is perhaps that known as " cotton bagging," which derives its name from the fact that it is used in the manufacture of bags for transporting raw cotton from the United States of America . It is a heavy fabric 42 in. wide, and weighs from 2 to 22 lb per yard . A similar, but rather finer make, is used for Sea Island and other fine cotton, and for any species of fibrous material; but for grain, spices, sugar, flour, coffee, manure, &c., the threads of warp and weft must lie closer, and the warp is usually single . For transporting such A C substances as sugar, it is not uncommon to line the bag with paper, which excludes foreign matter, and minimizes the loss .

Although there are large quantities of seamless bags woven in the

loom, the greater part of the cloth is woven in the ordinary way . It is then cut up into the required sizes by hand and by special machines, and afterwards sewn by one of the chain-stitch or straight-stitch bag sewing-machines .
