Preparation method of antibacterial and ultraviolet-proof multifunctional rayon dyed knitted fabric

Abstract

The invention discloses a preparation method of an antibacterial and ultraviolet-proof multifunctional rayon dyed knitted fabric. The method comprises the following steps of crushing and grinding tai chi stone to obtain nano tai chi stone, uniformly mixing the nano tai chi stone with rayon spinning liquid, performing wet spinning to prepare tai chi stone / rayon composite fiber, and weaving and processing a tai chi stone / rayon fiber composite knitted fabric; soaking the Tai chi stone / rayon fiber composite knitted fabric in a low-temperature low-alkali scouring agent; putting the Tai chi stone / rayon fiber composite knitted fabric into a container, dissolving a quaternary ammonium salt cationic modifier with water, and injecting the quaternary ammonium salt cationic modifier into the container for modification; putting the modified fabric into a dyeing machine, and dissolving reactive dye with water to realize low-temperature dyeing; carrying out composite finishing on the dyed fabric through quaternary ammonium salt type polyether modified siloxane and nano tai chi stone / polyacrylate emulsion to obtain a tai chi stone / rayon fiber composite fabric; and finally, carrying out cleaning and airing to obtain the finished antibacterial and ultraviolet-proof multifunctional rayon dyed knitted fabric.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a method for preparing multifunctional rayon dyed knitted fabrics with antibacterial and anti-ultraviolet rays. Background technique [0002] Preventing ultraviolet rays from harming the human body has attracted the attention of consumers. Ultraviolet rays in the solar spectrum not only make textiles fade and embrittle, but also cause sunburn and aging of human skin, resulting in melanin and stains, and more seriously, it can induce cancer and endanger human health. Therefore, the targeted development of knitted fabrics with anti-ultraviolet properties is an effective way for the human body to prevent daily ultraviolet radiation. However, considering that the human body is prone to sweating in summer, and if it is not cleaned in time, it is easy to induce bacterial infection, a knitwear with dual functions of antibacterial and anti-ultraviolet rays has been developed to ...
