Protective textile with tungsten and manufacturing method thereof
11162195 · 2021-11-02 ·

In one aspect, a method of manufacturing a protective textile may include steps of (a) twisting a first yarn with a tungsten filament; and (b) using a second yarn to cover the yarn-tungsten product generated in step (a). The yarn generated in step (b) is further twisted with an elastic spandex. In one embodiment, the first yarn is selected from a group of Nylon, Polyethylene Terephthalate (PET), cotton yarn, bamboo fiber and Tencel. In another embodiment, a Polyethylene (PE) fiber is the second yarn, and the third yarn may include Nylon, PET or PE. The protective textile is advantageous because it is light, thin, soft and highly cut resistant. Also, it has great electrical conductivity and chemical stability, and it is not easy to deform after washing.

Method for manufacturing antibacterial copper nanofiber yarn

A method for manufacturing antibacterial copper nanofiber yarn includes steps of: raw material mixing operation and spinning operation, where the raw material mixing operation is to mix dry copper nanopowder having a particle size of no more than 48 nm with fiber slurry; and the spinning operation includes the following steps: mixing and stirring the copper nanopowder and the fiber slurry so that the copper nanopowder is uniformly distributed in the fiber slurry to prepare a mixed material; drying the mixed material; hot-melt drawing the mixed material, i.e. drawing out yarn with the dried mixed material through a drawing machine to form first-stage yarn; stretching and extending, i.e. passing the first-stage yarn through a plurality of rollers to stretch the first-stage yarn; naturally air-cooling the first-stage yarn to form second-stage yarn; and collecting yarn, i.e. collecting the second-stage yarn to fabricate an antibacterial copper nanofiber yarn finished product.
