Abstract

The invention discloses an environment-friendly fabric stiffness enhancer and a preparation method thereof. The environment-friendly fabric stiffness enhancer is prepared by (1) adding deionized waterinto a reactor and heating the deionized water to 80-100 DEG C, (2) adding an initiator and an emulsifier to stop heating, (3) slowly adding a mixture of aqueous polyacrylic acid and aqueous polyurethane into the reactor drop by drop at a rate of 10 to 20 mL / min, (4) keeping the temperature for two hours, (5) ultrasonically dispersing chitosan, ethanol, nanoparticles, gelatin and triethanolamineto obtain a uniformly dispersed mixed liquid, and (6) mixing the solutions of the steps (5) and (4) through stirring to obtain a finished product. The environment-friendly fabric stiffness enhancer has the advantages of low cost, good effect, product storage stability, good water solubility, environmental friendliness and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of textiles, and more specifically relates to a preparation method of an environment-friendly fabric stiffness enhancer. Background technique [0002] Fabric stiffness enhancement finishing is an important fabric finishing method, which can make the fibers in the fabric yarn bond under certain conditions by impregnating the fabric hardness enhancer, so that it can be bonded between fibers or between fibers. Film or cross-linking occurs on the surface, which makes the fabric feel crisp and thick. [0003] At present, most of the stiffness enhancers in China are modified melamine-formaldehyde resins-urea-formaldehyde resins, which contain a small amount of formaldehyde, but can meet the stiffness requirements of most textiles. With the development of the economy and the improvement of people's living standards, people have higher requirements for textiles. Therefore, the multifunctional finishing of textiles ...
