Problems solved by technology

However, soybean fiber fabrics have low reactivity and poor heat resistance. They are prone to yellowing and decrease in strength when dry heat is above 120°C, and the fabric feels hard. The existing methods cannot be used for the finishing of soybean fiber fabrics.
Moreover, the currently commonly used anti-pilling finishing agent contains a certain amount of formaldehyde, which does not meet the requirements of ecological textiles, and has a great impact on the feel and style of the fabric after treatment.

Abstract

This invention discloses a fuzzing-pilling resisting finishing method for soybean fiber fabric. It makes grafting modification to soybean fiber fabric, finishes by resin finishing agent. The monomer for grafting modification is diacritic acid or methacrylate of diatomic alcohol or with other active group, the finishing agent is organic silicon modified polyacrylate dispersion or modified polyurethane like finishing agent. Said invention has fine washing resistance and no formaldehyde in process agent.

Description

technical field [0001] The invention relates to a method for anti-pilling finishing of soybean fiber fabrics, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] Soybean fiber is a new type of regenerated protein fiber independently developed by Chinese scientific and technological personnel. It is wet-spun from a mixture of soybean protein and polyvinyl alcohol, and has undergone acetalization and cross-linking treatment in the post-spinning process. Soybean fiber can be blended or interwoven with conventional textile materials such as wool, cashmere, silk, viscose, bamboo fiber, Tencel, Modal, polyester, and nylon. Because soybean fiber has excellent properties such as good moisture absorption and moisture conductivity, soft hand feeling, soft luster, and comfortable wearing, it has been used by the textile industry to develop new clothing fabrics and home textiles, and most of them are blended and i...
