Sažetak
Mechanical faults on woolen fabrics are often the result of insufficient mechanical properties of wool warp that must be achieved to ensure smooth process of weaving. Conventional sizing is not appropriate for the preparation of wool yarn for weaving because of sensitivity of wool fibers to high temperatures. For that reason, wool warp is mostly prepared by using the waxing procedure whereby protruding fibers on the yarn surface are smoothed. In this way, its friction and elongation properties are improved. Another option is a cold sizing. It is a process, which aims to achieve the effect of conventional sized warp, but without the use of high temperatures. Cold sizing has been proved to be a good solution for wool warp sensitive to dynamic stresses during the weaving process. This paper describes advantages of the cold sizing procedure to warp waxing. The number of end breakages on the weaving machine, lengths of a faulty place in the thread marked in the inspection room of the weaving mill, and times spent for manual retouching are compared. The type of fabric, for which an increase in costs for cold sizing is justified, is also determined.
