Problems solved by technology

While cashmere has many advantages, it also has its own disadvantages. Cashmere belongs to protein fiber and can be eaten by insects. Therefore, moth-eaten phenomena often occur during storage. After it is made, it is soaked with nano-antibacterial additives to make the cashmere garment have antibacterial function. Because the fibers of the cashmere garment have cohesion with each other, it cannot be soaked and dried at a higher temperature. If the temperature is too high, it will This will cause fiber brittle cracks and felt shrinkage in cashmere garments. Once fiber brittle cracks and felt shrinkage occur in cashmere garments, it will be difficult to deal with later. Therefore, the soaking and drying temperature of cashmere garment nano-antibacterial additives is generally 75-80 degrees. The temperature of 75-80 degrees can only keep the nano-antibacterial additives on the surface of cashmere garments, because the temperature of 75-80 degrees cannot make the scales on the surface of cashmere fibers open, so when cashmere garments are worn for a period of time, The nano layer on the surface of cashmere garments will fall off, thus losing the antibacterial function

Embodiment Construction

[0009] The production method of an antibacterial woolen cashmere yarn of the present invention will be further described in detail below through specific examples.

[0010] A production method of antibacterial woolen cashmere yarn, comprising the steps: A. cashmere selection: selecting cashmere loose fibers with a fineness of 16-16.5 microns and a length of 34-36 mm; B. dyeing: dyeing the cashmere loose fibers, Drying and opening to obtain colored cashmere loose fibers; C, antibacterial treatment: put colored cashmere loose fibers into a dyeing vat, the bath ratio of the colored cashmere loose fibers to the liquid in the dyeing vat is 1:8, and the liquid in the dyeing vat is 1:8. It is water at a constant temperature of 40 degrees, and then the nano antibacterial auxiliary is added to the liquid in the dyeing vat. The addition amount of the nano antibacterial auxiliary is 3% of the mass of the cashmere loose fiber, and then the dye vat is balanced and heated, and the temperatur...

Abstract

The invention relates to a production method of antibacterial woolen cashmere yarn. The production method comprises the following steps of A, cashmere selection, wherein cashmere loose fibers with the fineness being 16-16.5 micrometers and the length being 34-36 mm are selected; b, dyeing: dyeing, drying and opening the cashmere loose fibers to obtain colored cashmere loose fibers; c, antibacterial treatment; d, dehydration: carrying out dehydration treatment on the wet antibacterial cashmere loose fibers through a centrifugal machine, and controlling the moisture content of the dehydrated antibacterial cashmere loose fibers to be 23-25%; e, high-temperature drying and permeation: putting the antibacterial cashmere loose fibers with the water content of 23-25% into a radio frequency dryer for drying at the drying temperature of 125-130 DEG C, and enabling the high temperature to open hair cuticles on the surfaces of the cashmere loose fibers and enable the nano-antibacterial additive to deeply permeate into the cashmere loose fibers; f, opening; g, wool blending; and H, spinning the antibacterial cashmere loose fibers subjected to the health maintenance treatment through a traditional roving process including carding, wobbling, spooling, doubling and two-for-one twisting to obtain antibacterial cashmere yarns, so that cashmere garments made of the antibacterial cashmere yarns have better and long-term antibacterial performance.

Description

【Technical field】 [0001] The invention relates to the technical field of textiles, in particular to a production method of antibacterial woolen cashmere yarn. 【Background technique】 [0002] Cashmere is a thin and curved fiber, which contains a lot of air and forms an air layer, which can defend against the invasion of external cold air and keep the body temperature from decreasing. Cashmere is much thinner than wool, and the outer scales are also finer and smoother than wool, so it is light, soft and tough. It is especially suitable for making underwear. When worn close to the body, it is light, soft, soft, smooth and very comfortable, which is unmatched by any fiber. While cashmere has many advantages, it also has its own shortcomings. Cashmere is a protein fiber, which can be eaten by insects. Therefore, insect-eaten phenomenon often occurs during storage. In order to solve this technical problem in the prior art, cashmere garments are generally used. After it is made, ...
