Technical Field

The invention relates to textile materials, in particular to a preparation method and application of medical supplies series yarns.

Background

At present, the scientific community has determined that human skin is not allergic to chemical fibers per se, but is allergic to auxiliary agents contained in the chemical fibers, wherein silicone oil is one of the main agents. Similarly, the adhesive in the medical composite fabric is also considered to have toxicity, the chemical glue is the main one, the stronger the glue toxicity and the irritation are, the edible rice glue does not contain formaldehyde, but has low viscosity and high price. Therefore, 99.9% of domestic sewing thread suppliers add a large amount of silicone oil to the thread for lubrication in order to improve the sewability of the thread, and after the water washing process, the silicone oil and other harmful substances contained in the sewing thread are basically removed from common clothes sewed by the thread, but the medical protective articles sewed by the thread without water washing have great potential safety hazard. China is a world large country for producing medical supplies, and the sewing thread for sewing the medical supplies does not fundamentally solve the problems of no silicone oil, thread breakage and the like so far. Medical supplies such as medical grid paper wipes used by medical personnel have not been produced without glue.
