The weft stop motion controls the correct insertion of the weft into the shed. Warp and weft stop motions will stop the loom most immediately when a warp end or a pick breaks off. It avoids the faults disturbing the fabric surface. It helps not degrading the fabric quality. The feeders are supplied together with various outfits and adjustment possibilities, which vary according to the yarn type and count and to the insertion system used.
Selvedge are special hooked needle driven by a cam which produces, after cutting, the insertion of the protruding thread end into the subsequent shed, thus forming a stronger edge. The basic function of any selvedge is to lock the outside warp threads of a piece of cloth and so prevent fraying. The selvedge should be strong enough to withstand the strains of the stenter in the finishing process. - The selvedge should have a neat and uniform appearance.
A draft indicates the number of heald shafts used to produce a given design and the order is which warp ends are threaded through the heald eyes of the heald shaft. The principle of drafting (i.e. putting of ends on different healed shafts) is that ends which work in different order require separate heald shafts. To keep matters simple, we can also say that the ends that work alike are put on the same heald shaft.
The basic mechanisms in any type of looms can be classified into Primary (shedding, picking & beat up), secondary and Auxiliary motions. Shedding opens the warp sheet into layers. The picking causes the shuttle carrying weft to be propelled from one end of the loom to another. The beat up motion lays the previously laid weft to the fell of the cloth. The secondary motion comprise of take up and let off motions. The auxiliary motions consist of the warp stop, weft stop and warp protector motions.
Weaving looms can range from quite simple to very complex. Looms have been used to produce cloth for thousands of years, and while technology has improved the loom, the basic strategies and practices remain much the same. Understanding the parts of the loom can help you learn to weave or simply learn a bit more about how weaving works.
Batik is a textile art used to print or decorate the fabric and also called as "wax writing". It is a technique of covering parts of fabric which will not receive color. The creation of batik involves three major processes – waxing, dying and de-waxing.
