In order to meet the requirements of the pure cotton fabric characteristics of the terry towel, an ideal yarn for the antibacterial terry towel needs to have the following characteristics: (1) the addition amount of the antibacterial fiber is as low as possible, so that the addition of the fiber does not influence the effect of the cotton yarn towel of the whole fabric, and even can improve other properties of the towel, such as quick-drying property; (2) the antibacterial agent can meet the requirement of antibacterial indexes specified by standards, can be produced in batches stably, and can keep the durability of the antibacterial effect in multiple practical use processes; (3) it is required to be fluffy, soft and water-absorbent.

The zinc oxide antibacterial regenerated terylene is prepared by dissolving a zinc ion antibacterial material into a regenerated terylene solution and spinning the solution into functional short fibers, and has the advantages of broad-spectrum antibacterial property, high antibacterial rate, lasting antibacterial effect, safety and harmlessness to human bodies, and wide ecological environment-friendly application range. The antibacterial effect on staphylococcus aureus, escherichia coli, candida albicans and the like is obvious; the antibacterial mechanism of zinc oxide is mainly divided into two types: (1) photocatalytic antibacterial mechanism;

(2) contact sterilization mechanism.

How to prepare blended yarns with good antibacterial performance is a problem to be solved urgently by the technical personnel in the field.
