Abstract

The invention discloses fabric stiffening adhesive paste, a preparation method thereof and forming cloth. The fabric stiffening adhesive paste comprises the following raw materials: vinyl acetate, organosilicone monomers containing unsaturated double bonds, butyl acrylate, polyvinyl alcohol, a silane coupling agent, a sodium salt chelating agent, a defoaming agent, deionized water, an initiator and a preservative. The finished fabric stiffening adhesive paste does not contain hazardous substances such as formaldehyde, heavy metal and the like, is free of toxicity and off-odor, is safe and reliable, has very strong adhesive force to multiple chemical fabrics, and is applicable to cotton cloth, chemical fabrics, linen, wool fabrics, silk and blended fabrics; the glossiness, hardness and hand feeling are improved without changing colored light of cloth, and the processed cloth does not easily absorb moisture and ease back and has storability.

Description

technical field [0001] The invention relates to the field of water-based adhesives, in particular to a fabric stiffening glue, a preparation method thereof and a setting cloth. Background technique [0002] Because the fabric itself is relatively soft, when the user has requirements for the hardness and stiffness of the fabric, such as using the fabric to produce shoe cloth, shoe cloth, advertising cloth, etc., the cloth that has not been pretreated cannot meet the user's requirements. . Therefore, it is necessary to carry out sizing pretreatment on the fabric. The traditional method is to use starch as the sizing material. However, the worldwide "food crisis" has become increasingly severe. The domestic food price has increased significantly in recent years, and the price of starch has risen. The use of starch sizing not only wastes food resources, but also increases production costs. And, adopt starch sizing, because the nutrient content of the cloth after sizing is comp...
