What are the production methods of anti-mite fabrics?

Like other functional fabrics, there are various technical methods for knitwear to obtain anti-mite function. The production methods of anti-mite fabrics include: functional fiber method, fabric finishing method, and high-density fabric method, which will be described in detail below.

1. Functional fiber method

In this method, the anti-mite finishing agent is added to the fiber-forming polymer, and the anti-mite fiber is made after spinning. Through this method, the fiber material can be given anti-mite performance. There are two specific implementation methods: one is to add anti-mite finishing agent during polymer polymerization, and then spin; the other is to make anti-mite masterbatch, and then mix it with polymer chips, In the spinning process, the anti-mite finishing agent is added to the fiber to chemically modify the fiber. The latter method is often used to develop anti-mite fibers and anti-mite cotton.

2. Fabric finishing method

The anti-mite finishing method is to post-finish the fabric with an anti-mite finishing agent to achieve the anti-mite effect. This is a conventional technology, and its implementation methods include spraying, padding, coating, etc. The key to this technology is the selection of anti-mite finishing agents and the preparation of finishing agents. Commonly used methods are:

(1) Grafting active groups that can bind to fibers on the anti-mite compound;

(2) The combination of the reactive group on the anti-mite compound and the fiber is realized by the cross-linking agent;

(3) When the anti-mite agent is filled into microcapsules, it can be combined with the fabric through film-forming materials such as resins and coating agents. The anti-mite agents used in this type of finishing include chemical substances such as phenylamide, naphthol compound isobornyl, ethyl thiocyanate and other plant substances such as pyrethrum extract, eucalyptus oil, and persimmon astringent.

3. High-density fabric method

This method is derived from plastic film, but plastic film is not breathable and feels stuffy. The anti-mite effect is achieved by the high-density fabric itself. This method is an isolation method. This method mainly relies on the tightly woven fabric or the microporous structure of the fabric to prevent the invasion or penetration of the mites, but it cannot repel or kill the mites. If such a high-density fabric is used to make bed sheets, the mites on the bed sheet cannot enter the mattress under the bed sheet, but the mites can still rely on human secretions to survive and reproduce.
