Abstract

The invention provides a stiffening agent and a preparation method thereof. The preparation method includes the following steps that 1, stearyl methacrylate, isobutyl methacrylate, n-propyl methacrylate, maleic anhydride, lauryl acrylate, silico triol alginate, glycerol monolaurate, modified soybean phospholipid, vanillin, keratin and deionized water are mixed and stirred to obtain a mixture A; 2,potassium persulfate, silver nitrate and deionized water are mixed and stirred to obtain a mixture B; 3, half of the mixture A and half of the mixture B are mixed and kept warm; 4, the remaining mixture A and the remaining mixture B are dropwise added to obtain a reaction solution C; 5, the reaction solution C is cooled down and a sodium hydroxide solution is added for stirring; 6, polyvinylpyrrolidone, polyethylene oxide, polyanionic cellulose and polyvinyl alcohol are added for stirring to obtain a mixture; 7, the mixture is cooled to room temperature and discharged to obtain the stiffeningagent. The stiffening agent has stable performance, long bending length, excellent breaking strength and good stiffening effect.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a stiffening agent and a preparation method thereof. Background technique [0002] Stiffeners are substances designed to improve the appearance of fabrics, increase fabric elasticity and fullness, and impart stiffness. Stiffening finishing is a finishing process in which the stiffening agent forms a thin film or cross-links inside, between fibers or on the surface of fibers by padding, so that the fabric has a stiff, thick and plump feel. At present, this process mainly uses urea-formaldehyde resin as the stiffening agent. This kind of stiffening agent is easy to obtain, low in cost, fast in curing speed and high in stiffness. However, after finishing, the fabric feels rough, especially the release of free formaldehyde. It will cause certain harm to the human body. Therefore, it is of great significance for the textile industry to research and develop a novel stiffening agent w...
