Yarn with controllable color and style

Abstract

The invention relates to yarn with the controllable color and style. The yarn is warp, the warp includes an inner layer yarn core and outer layer yarn, the fineness of the warp is 6 to 40 English counts, the fineness of the inner layer yarn core is 40 to 100 English counts, the inner layer yarn core adopts a Z twist direction and a S twist direction to spin, the outer layer yarn adopts the same twist direction as the inner layer yarn core to spin after wrapping the inner layer yarn core, and when spun into yarn, the twist factor of the inner layer yarn core is 350 to 520, and the twist factorof the outer layer yarn is 300 to 350. The inner layer yarn core is cellulose fiber filaments and blending of synthetic fiber filaments, the cellulose fiber filaments are natural color or white, the outer layer yarn is cellulose fiber filaments, the twist, counts, and materials of the outer layer yarn and the inner layer yarn core are controlled separately, so that the outer layer yarn has color after the warp is dyed, and the ring dyeing effect that the inner layer yarn core is comparatively white or light can be achieved.

Description

technical field [0001] The invention relates to a yarn with controllable color and style, belonging to the technical field of denim fabrics. Background technique [0002] The warp yarn of denim fabric is mainly dyed with indigo dye. Because indigo dye has poor planarity and small molecular structure, it has low affinity with cellulose fiber, so the dyeing rate is also low. Using the particularity of indigo dyeing to impervious to the core, washing denim garments with water can obtain different colors and styles, and after stone grinding, it has both three-dimensional and layered effects; When it comes into contact with cotton yarn, due to the limitation of the particle size of the dye itself, the dye cannot penetrate evenly, thus forming a phenomenon that more dye is dyed on the outer layer of the yarn and less dye is dyed on the core of the yarn. When washing denim garments, the dye on the yarn is peeled off layer by layer, and the color exposed on the outermost layer beco...

AI Technical Summary

Problems solved by technology

[0003] In the process of dyeing yarn with indigo dye, the dyeing stability is not easy to control, and its dyeing unevenness will change with the yarn blending, twist coefficient or other production conditions
