Embodiment 1

[0018] as attached Figure 1-2 As shown, the yarn with controllable whiteness of the present invention is a warp yarn, and the warp yarn includes an inner yarn core 1 and an outer yarn 2 covered outside the inner yarn core 1; the inner yarn core 1 is A single synthetic staple or a blend of synthetic staples, the outer yarn 2 is a single cellulose staple or a blend of cellulose staples; the warp yarn has a fineness of 6 to 40 pounds, and the inner yarn The fineness of the core 1 is 40-100 lbs; the inner layer yarn core 1 adopts Z twist direction or S twist direction to weave, and the outer layer yarn 2 and the inner layer yarn core 1 are wrapped with the inner layer yarn Core 1 is spun with the same twist direction, the twist coefficient of the inner layer yarn core 1 is 350~520 after spinning, and the twist coefficient of the outer layer yarn 2 is 300~350.

[0019] The single synthetic fiber staple of the inner layer yarn core of the present invention is polyester, nylon, pol...

Embodiment 2

[0036] as attached Figure 3-4 As shown, the difference between this embodiment and Embodiment 1 is: after the outer layer yarn 2 is covered with the inner layer yarn 1 core, the twist direction opposite to that of the inner layer yarn core 1 is used for weaving, and the inner layer yarn core 1 is twisted after spinning. The twist coefficient is 300-350, and the twist coefficient of the outer yarn 2 is 350-520.

[0037] During the specific application of this embodiment, the proportioning of raw materials and the production conditions of the following embodiments can be adopted:

[0038] Warp fineness Inner yarn core fineness Inner yarn core twist coefficient Outer yarn twist coefficient white core example 1 10 lbs 40 lbs 300 450 25% Example 2 10 lbs 60 lbs 300 450 15%

[0039] It can be seen from the example in the above table that as long as the fineness of the inner yarn core 1 and the overall warp yarn is controlled, the whi...

Abstract

The invention relates to yarn with controllable white cores. The yarn is warp. The warp comprises an inner yarn core and outer yarn wrapped outside the inner yarn core. The inner yarn core is single synthetic fiber staple or blended synthetic fiber staple, and the outer yarn is single cellulose fiber staple or cellulose fiber staple blended. The fineness of the warp yarn is 6-40 counts, and the fineness of the inner yarn core is 40-100 counts. The inner yarn core is spun in Z-twist or S-twist direction, and the outer yarn is wrapped with the inner yarn core and the twist direction is the sameor opposite to the direction of the inner yarn core. The cross-sectional area of the inner yarn core is inversely proportional to the twist factor of the inner yarn core. The larger the twist factor of the inner yarn core is, the smaller the cross-sectional area of the inner yarn core is. As long as the number of inner yarn core and an integral warp is controlled, the dyeing white core degree of the warp can be controlled to a certain extent. The production and economic benefits are improved.

Description

technical field [0001] The invention relates to a yarn with controllable whiteness, which belongs to the technical field of denim fabrics. Background technique [0002] The production of denim clothing is different from traditional dyed cloth. It needs to be warp dyed and sizing before weaving into cloth. The finished clothing also needs to go through processes such as hand rubbing and stone washing to form a unique distressed effect. And this "distressed" effect comes from the white core formed by the warp dyeing using indigo dye. Indigo dye is different from other dyes, it needs to be reduced before it can be dyed, and then oxidized and fixed on the yarn. When indigo dyeing is dyed, the dye is not easy to penetrate into the yarn core, and it must go through multiple dyeing and oxidation to form a darker color. However, it is difficult to control the white core degree of the warp yarn after multiple dyeing (the percentage of the inner yarn core and the overall yarn mass p...
