Sizing Before the cotton is woven, the 'warp' (longways) yarn may be 'sized', for the purpose of adding strength and smoothness to withstand the rigours of the weaving process. Size, for cotton, is normally a gluey, gelatinous, starch based substance which dries on the yarn. Weaving The principle of weaving cotton cloth is essentially the same whether performed on the most primitive handloom or the most advanced modern power loom, consisting of the crossing or interlacing the crossways threads ('weft', carried by means of a shuttle) with the lengthwise threads (warp). There are three main operations on a loom: shedding (lifting the warp to allow the weft to pass through particular threads), picking (passing the shuttle from one side of a warp to the other) and beating up (to tighten up the weft thread). There are many ways to weave cloth, from the simplest plain weave to the weaving of cloth with complex patterns on a Jacquard loom. NR View the Weaving collection to find out more > |
