Poplin fabric design composite fabric information

When designing poplin, it is advisable to use the same number of warp and weft yarns. 2. The initial configuration of the warp and weft yarns. The warp yarn twist should be smaller and the weft yarn twist should be larger (larger rigidity and less entanglement with the warp yarn). This not only helps the rhombus particles to stand out clearly, but also improves the feel and luster of the fabric. 3. Configuration of warp and weft twist directions: Warp and weft yarns adopt different twist directions. In this way, the fiber tendencies are consistent, the reflection is good, the contact areas are loose, and the cohesion is small, which is conducive to clear and protruding particles. 4. Raw yarn requirements In order to fully reflect the style characteristics of poplin fabrics, the yarn must meet the requirements of “light, clean, even, and firm”, that is, the yarn has less hairiness, fewer and smaller neps and impurities, even slivers, and good strength. Among them, the evenness is most closely related to the poplin style, especially the evenness of the weft yarn, which has the most significant influence. Uneven yarn dryness will cause the cloth surface to be uneven, rough to the touch, and have obvious stripes. Therefore, poplin fabrics usually use long-staple cotton with fine and long fibers. For dark poplin, the maturity of the cotton fibers should be good so that the dyeing can be even, dark and bright. 5. Others (1) Selvage: Ordinary poplin does not need selvage because its Pj>Pw, the weft shrinks and the warp shrinks. Adding selvage will produce tight or loose edges, which will not have a good effect. (2) Weaving and The style is combined, and the warp and weft are mostly made of extra-fine special strands or fine warp strands and thick weft yarns. (3) In the dyeing and finishing of pure cotton poplin, great attention should be paid to the pre-treatment process. Especially the poplin with high tightness must be fully destocked, boiled (cooked) thoroughly, bleached (whitened) well, and fully treated. When washing and wearing, pay attention to the dye fastness index.
