Abstract
The invention provides a preparation method of cross-linked resin for spinning. The preparation method comprises the following steps: carrying out a cyclization reaction on glyoxal and urea, thus obtaining a reaction solution; enabling the reaction solution to react with formaldehyde, and generating first condensate; carrying out an etherification reaction on the first condensate and an etherifying agent; finally modifying by adding a bleaching agent and water. The invention also provides the application of the cross-linked resin for spinning. The application comprises the following steps: selecting the cross-linked resin prepared by the preparation method; drying the cross-linked resin under the action of a catalyst when the temperature is 60 DEG C to 80 DEG C; baking under 145 DEG C after carrying out pressing and forming on fabric. According to the cross-linked resin prepared by using the preparation method, free formaldehyde on the surface of a cloth cover is low; meanwhile, by using the cross-linked resin, not only can original characteristics of a product be kept, but also the color of the cloth cover is increased, the color is fresher, the grains are clearer, and the cross-linked resin can be used for special technology, reworking and shading treatment of the cloth cover.
Description
technical field [0001] The invention relates to a resin and its application, in particular to a preparation method and application of a cross-linked resin for textile use. Background technique [0002] In the 1930s, people began to study anti-wrinkle and anti-shrinkage finishing agents because of the obvious wrinkling and shrinkage deformation of fabrics during the washing process. After decades, anti-wrinkle and anti-shrinkage treatment has become one of the important processes in textile dyeing and finishing. So far, dozens of varieties have been developed, such as: urea-formaldehyde resin initial shrinkage body, hexamethylolmelamine formaldehyde resin, Initial contraction body of dimethylol dihydroxyethyl ethylene urea resin, initial contraction body of dimethylol triazone resin, etc. With the improvement of people's living standards and the enhancement of environmental protection awareness, reducing the release of formaldehyde and functional products have become the goa...
