A preparation method of hemp-cotton blended yarn containing infrared heating fiber

Abstract

The invention discloses a preparation method of cotton-linen blended yarn containing infrared heating fibers. The method comprises the following steps: (1) blending prepared cotton-linen blended functional fibers with the infrared heating fibers in proportion, plying and twisting to obtain cotton-linen blended yarn containing the infrared heating fibers; spinning the obtained yarn into raw thick yarn by mixing and matching, and then scouring and bleaching the thick yarn; (2) carrying out semi-degumming on the thick yarn; (3) treating the obtained thick yarn by using antibacterial liquid; (4) carrying out bio-enzyme pretreatment before dyeing; (5) softening, oiling and drying: softening the cotton-linen blended yarn containing the infrared heating fibers after bio-enzyme pretreatment, oiling and drying to obtain dried cotton-linen blended yarn containing the infrared heating fibers; (6) dyeing; (7) carrying out wet spinning to obtain spun yarn; drying and then carrying out tight tube winding to obtain a finished product. The product prepared by the method has the characteristics of having the functions of health care and physical therapy, and being high in quality, bright and soft, good in neatness, less in impurity content and low in strength loss.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of hemp-cotton blended yarn containing infrared heating fibers. Background technique [0002] In the field of textile technology, yarn is the key to ensuring the quality of textile products. Scientifically and effectively selecting and blending various yarns and appropriate blending ratios is not only related to the cost of the product, but also related to the quality of the product. At present, in the linen textile industry, flax fibers are blended with other fibers to produce linen blended yarns, such as blending linen with special fibers, so as to improve the roughness and poor hand feeling of linen fabrics while maintaining the advantages of linen. [0003] Hemp fiber has excellent moisture absorption and perspiration performance, natural antibacterial health care performance, good soft and comfortable performance, excellent anti-ultraviolet ...

AI Technical Summary

Problems solved by technology

[0005] Apocynum is an excellent fiber with the quality second only to ramie among hemp fibers. If it is blended with cotton fiber or chemical fiber with single fiber quality, the effect is better. The application of apocynum fiber has involved many textiles, but in the production of fibers , due to its smooth surface without curling and small cohesion, it is easy to scatter in textile processing, the production rate is low, and it affects the quality of yarn

Because the quality is not well controlled, it is very difficult to produce yarn and fabric, and the quality cannot be guaranteed

[0006] When people sleep in bed in winter, they are often affected by the coldness of the bedding, and it is easy to have a bad rest, which seriously affects people's sleep quality.

At present, the traditional jacquard fabrics are mainly pure cotton fabrics, which only have the traditional characteristics of softness and moisture absorption. They do not have the ability to absorb the infrared rays reflected by the sun and the human body and convert them into heat energy. Single, lack of three-dimensionality

[0007] At present, there is a lack of a preparation method for producing hemp-cotton blended yarns containing infrared heating fibers with health care and physiotherapy functions
