Abstract

The invention provides a preparation method of a fabric stiffening agent. The method comprises the following steps that firstly, (2-acroloyl-oxygen-ethyl) quaternary amine alginate is prepared, 1,3-di(ethylene oxide methyl)-5-(2-allyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-triketone, allyl cyclodextrin, methacrylic acid isobutyl ester and (2-acroloyl-oxygen-ethyl) quaternary amine alginate are used as monomers for emulsion polymerization, dimethylol dihydroxy ethylene urea is added for a polycondensation reaction, and the fabric stiffening agent is obtained. The method is simple and easy to implementand has low dependence to equipment, the prepared fabric stiffening agent has higher stiffness, anti-bending length and breaking strength and more excellent performance stability, the stiffening effect is better, and the agent has no harm to the human body.

Description

technical field [0001] The invention relates to the technical field of fabric materials, in particular to a fabric stiffening agent and a preparation method thereof. Background technique [0002] Stiffening agent is a kind of fabric auxiliary used to improve the appearance of fabrics, increase the elasticity and fullness of fabrics, and impart stiffness. It forms a thin film or produces cross-linking inside, between fibers or on the surface of fibers, so that the fabric has a stiff, thick and plump feel. It is widely used in the finishing process of decorative fabrics, especially for curtains, bags, wares Stiff finishing of knitted fabrics and interlinings. [0003] At present, the common stiffening agents are mainly urea-formaldehyde resin type and acrylate series. The former contains the problem of free formaldehyde release, which does not meet the environmental protection requirements, and after finishing, the fabric feels rough; the latter has a wide variety of syntheti...
