There are two ways to apply fancy yarn in weaving process of woven fabric. One is that both warp and weft are fancy yarn, or all warp or all weft fancy yarn, which is widely used in weaving thick, stiff and thick fabrics. In particular, some irregular fancy lines make the irregular distribution of cloth surface more unique, such as cotton and linen yarn dyed slub fabric: warp 133tex pure ramie slub yarn, weft 54.4tex * 2 Gray ramie cotton yarn, plain weave weaving. Generally speaking, less fancy yarn is used for both warp and weft. Due to more cloth surface decoration, there is no feeling of coarseness and conciseness. On the contrary, it is too messy. As a result, the problems of too heavy cloth surface and low weaving efficiency appear, and the production cost rises. The second is to arrange fancy yarn and ordinary yarn in a certain proportion in warp and weft yarn, or warp or weft yarn, adjust the warp and weft density, and make the fancy yarn have special appearance and good wearability by embellishing it in the fabric. Based on the principle of less but better, it can highlight the three-dimensional effect without increasing the cost too much, and the weaving process is more convenient and the production efficiency is improved, For example, the warp yarn is 23dtex * 3 factory yarn, the yarn weft is 23dtex * 4 factory yarn 8 twists / cm, and the yarn weft (23dtex * 3 + 23dtex * 3 color yarn) is 4.65 twists / cm. The arrangement of yarn weft and yarn weft is 50 B 1 and 40 B 1 higher than that of yarn weft. The weave is small jacquard, and the lattice effect of longitudinal stripe and knot line embellishment is formed on the surface.
The design methods of fancy yarn woven fabric are as follows: adopting the difference of performance and thickness between fancy yarn and other warp and weft raw materials to form the appearance effect of strip, grid, dot, flash, concave convex strip on the surface of fabric; The combination of warp and weft color lines and fancy lines can form a three-dimensional effect with subtle colors; The change of the arrangement ratio of warp or weft and fancy lines forms a unique appearance; Using different longitude and weft density to match; Using different fabric organization and fancy thread matching; The performance and quality of fancy yarn fabric can be improved by using various finishing and dyeing and finishing features. It is worth noting that in order to reflect the color effect, structure effect and special effect of fancy yarn on the appearance of the final fabric, we should pay attention to the collocation of raw materials, the type of fancy yarn and the use of the fabric.
Fancy yarn has made great progress in the development and application of woven fabric products through years of efforts. Using fancy yarn in worsted fabric can not only keep the high-grade feeling of worsted fabric, but also make the surface of the fabric slightly fancy in quiet. It can also be used in woolen fabrics to produce the best-selling woolen products. Fancy yarn is the most widely used in yarn dyed products. It is widely used in thick, medium and thin fabrics. In addition, the application of natural fiber like products and fancy gauze is becoming more and more mature.
