Abstract

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.

Description

BACKGROUNDTechnical Field

[0001] The present invention relates to a method for manufacturing antibacterial fiber yarn, and in particular to a method for manufacturing antibacterial copper nanofiber yarn by mixing nanoscale copper powder with polymer slurry and then spinning the mixture.Related Art

[0002] Common man-made fiber products are usually used for people or pets to wear, including knitted fabrics, clothing, scarves, masks, gloves and other products. However, these fiber products being in the closest contact with people or pets are also the most likely to be contaminated by bacteria and breed pathogens, which is harmful to the users. Therefore, fiber products with antibacterial effects are in demand.

[0003] Generally, the so-called “antibacterial” mainly refers to controlling the parasitism and increase of microorganisms, inhibiting the reproduction of bacteria which are harmful to the human body and preventing the reproduction of bacteria in advance. Fibers and textiles are likely...
