Abstract
The invention relates to a washable environment-friendly stiffening agent and a preparation method thereof. The preparation method comprises the following steps of premixing polyvinyl alcohol, starch, a silane coupling agent and nano silicon carbide in a ball mill, reducing the particle sizes of the polyvinyl alcohol and the starch through ball milling, and fully mixing the polyvinyl alcohol and the starch with the nano silicon carbide; mixing water and an emulsifier to adjust the pH value and the temperature to form a mixed solution to be reacted; and mixing an initiator. The reaction speed, the reaction effect and the uniform distribution rate of the nano silicon carbide in the stiffening agent are effectively improved, the micro-agglomeration phenomenon of the nano silicon carbide is reduced, colloidal particles are avoided, the silane coupling agent is utilized to form organic matrix-silane coupling agent-inorganic matrix combination, and the characteristics of the nano silicon carbide are fully utilized, so that the stiffening agent provided by the invention has a better adhesion effect on the fabric, the treated fabric has a better stiffening effect, the wear resistance and the washing resistance of the fabric are effectively improved, and the stiffening agent does not contain formaldehyde, non-environment-friendly emulsifiers and cross-linking agents, and has environment friendliness and high stability.
Description
technical field [0001] The invention relates to a washable and environmentally friendly stiffener, in particular to a washable and environmentally friendly stiffener and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the economy and the improvement of people's living standards, people have higher and higher requirements for textiles. When processing fabrics such as curtain fabrics, direct stretch fabrics, wall coverings, luggage fabrics, etc., the fabrics need to have a certain degree of stiffness after processing. Especially warp-knitted fabrics have strict requirements on the stiffness of the fabric after processing. [0003] Fabric stiffening agent is a widely used textile printing and dyeing auxiliaries and an important fabric finishing method. It can make the fabric have a stiff characteristic by giving the fabric elasticity and fullness, and endow the fabric with a special feel and appearance. The research o...
