Description

A kind of processing method of high antibacterial towel yarn

【Technical field】

The invention relates to the technical field of yarn processing, in particular to the technical field of the processing method of high antibacterial towel yarn.

【Background technique】

Cotton-type fabric refers to the fabric woven from cotton yarn or cotton yarn and chemical fiber blended yarn. The characteristics of cotton-type fabric are: strong hygroscopicity and large shrinkage rate. Alkali resistance is not acid resistance. Cotton cloth is extremely unstable to inorganic acids, but organic acids are weak and almost indestructible. Cotton cloth is more resistant to alkali, and dilute alkali has no effect on cotton cloth at room temperature. Light fastness and heat resistance are average. Microorganisms have a destructive effect on cotton fabrics, which are manifested as not resistant to mold.

Bamboo charcoal fiber and its products are widely used in antibacterial fabrics because of their good antibacterial properties, super adsorption properties, and their unique functions of comfort, health, environmental protection, and health care. my country is a country with a large amount of bamboo resources. Bamboo charcoal fiber is convenient to obtain materials. It can effectively utilize my country's rich bamboo forest resources and develop unique products.

The cellulose content in Apocynum fiber is as high as 81.4%, the fiber strength is high, and it is soft to the touch, has strong moisture absorption capacity and strong corrosion resistance, and is known as the "king of wild fibers". Apocynum has strong antibacterial properties. Research data show that the antibacterial rate of Apocynum fiber to Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans can be as high as 50% and above. After more than 30 times of washing, the sterile rate of the fabric is still 10-20 times higher than that of ordinary fabrics.

Cotton yarn has the function of moisture absorption and perspiration, but it does not have the function of antibacterial. The cost of bamboo charcoal fiber is more expensive, and the material of apocynum fiber is less, so it is not easy to obtain. Therefore, it is necessary to utilize the advantages of bamboo charcoal fiber, apocynum fiber and long-staple cotton to develop novel yarns with moisture absorption and perspiration and antibacterial functions.
