Problems solved by technology

However, due to the short fiber length, low fiber strength and high short-staple rate of natural colored cotton, the pure spinning process can only spin low-count yarns, which is greatly restricted in the development of clothing fabrics. rare

Embodiment 1

[0012] 30% of dark brown colored cotton fiber (hand-pulled length 23.7cm, short-staple rate 15.7%), white cotton (hand-pulled length 27.0cm, short-staple rate 11%) 65%, spun silk content (fiber cut length 38cm) 5% Spinning the target yarn of 40 British counts; spinning 40 British counts comparison yarns with 30% of dark brown colored cotton fibers and 70% of white cotton. Compared with the comparison yarn, the target yarn spun, the yarn strength increased by 0.3cN / tex, the elongation at break increased by 0.32%, and the yarn evenness (CV m ) by 1.94%, 241 fewer fine places (-50% / km) and 390 fewer thick places (+50% / km). Except for a slight decrease in yarn strength, other indicators have improved significantly, especially the evenness index has improved significantly, indicating that even if 5% of real silk fiber is added to the blend, the performance of the colored cotton blended yarn can be significantly improved.

Embodiment 2

[0014] With dark brown colored cotton fiber (hand-pulled length 23.7cm, short-lint rate 15.7%) 50%, spun silk content (fiber cut-off length 38cm) 50% spinning 40 pounds target yarn; with dark brown colored cotton fiber (hand-pulled length 23.7cm, short-staple rate 15.7%) 50%, white cotton (hand-pulled length 27.0cm, short-staple rate 11%) 50% spinning 40 British count contrast yarns. The target yarn of spinning is compared with reference yarn, and yarn tenacity increases 2.8cN / tex, and elongation at break increases 1.35%, and yarn evenness (CV m ) decreased by 1.48%, fine details (-50% / km) by 218 and thick places (+50% / km) by 307. All aspects of performance of blended yarns are improved.

Embodiment 3

[0016] 30% of dark brown colored cotton fiber (hand-pulled length 23.7cm, short-staple rate 15.7%), white cotton (hand-pulled length 30.0cm, short-staple rate 15%) 30%, spun silk content (fiber cut length 38cm) 40% Spinning 40 British count target yarns; 30% of the corresponding dark brown colored cotton fiber (hand-pulled length 23.7cm, short-staple rate 15.7%), white cotton (hand-pulled length 30.0cm, short-staple rate 15%) 70% A Ne 40 control yarn was spun. The target yarn of spinning is compared with reference yarn, and yarn tenacity increases 3.2cN / tex, and elongation at break increases 2.59%, and yarn evenness (CV m ) decreased by 2.38%, fine details (-50% / km) by 376 and thick places (+50% / km) by 455. All aspects of performance of blended yarns are improved.

Abstract

The invention discloses a method of improving quality and performance of natural colored yarns through mixed fabric. The method comprises the steps as follows: using 5-50% natural colored cotton, 0-70% white cotton and 5-70% silk yarns to blend to make natural colored yarns, wherein the silk yarns are degummed and cut-off silk fibers, the white cotton is fine fleece or long-staple cotton; the carded yarn of the natural colored cotton uses refine combing, and the natural colored yarns are made by mixed fabric mode. Because the invention utilizes the true silk (silk yarn) as the mixed material of the natural colored cotton, the made yarns have good evenness and reduce the slub and thin sections and improve the strength and extending ratio of the yarns.

Description

technical field [0001] The invention relates to the production of textile yarns, in particular to a method for improving the quality and performance of natural colored cotton yarns through blending. Background technique [0002] Natural colored cotton is a new generation of green and environmentally friendly fiber, and it is a successful example of modern high-tech methods in fiber development and production. Because there is no need for bleaching and chemical dyeing, it can save the printing and dyeing process, reduce the cost of textiles, and protect the natural ecological environment from pollution. Natural colored cotton has a good development and application prospect. [0003] According to the forecast of the International Organic Agriculture Committee, in the next 50 years, 30% of the world's total cotton will be replaced by colored cotton. Natural colored cotton textiles will be one of the most competitive leading products in the international market in the 21st cent...
