Pressure Analysis on Medical Compression Hosiery and Property Research of Lycra/Nylon Double Wrapped Yarn

Abstract:

Compared Chinese and English medical compression hosiery standards, it can conclude a rational medical compression stocking pressure index. By researching stretch property, twist and scanning electron microscopes, it turns out that elongation at break of lycra/ nylon double wrapped yarn is increasing with the increase of lycra denier. This phenomenon is obvious at the beginning, and then it will level off. Breaking strength and breaking force is increasing with the increase of nylon denier. The increase of yarn twist makes yarn construction tight, thus double wrapped yarn is covered better and not easy to expose the yarn core.
