Abstract

The invention discloses a water-based imitation coating high-elasticity-and-stiffness finishing agent and a preparation method, and relates to the technical field of textile fabric after-finishing. The finishing agent is prepared from the following raw materials in parts by weight of 50-60 parts of an emulsion A, 100-120 parts of an emulsion B and 5-10 parts of a cationic blocked isocyanate cross-linking agent. According to the preparation method of the water-based imitation coating high-elasticity stiff and smooth finishing agent, the high-molar-mass epoxy modified polysiloxane emulsion A, the emulsion B prepared from amino polyether modified polysiloxane and a polyethyl silicate crosslinking agent and the blocked isocyanate cross-linking agent are reasonably compounded, and padding and finishing are performed on a fabric, so that the elasticity and stiffness of the fabric can be obviously improved, and the effect of a coating process is achieved. The obtained finishing agent is goodin softness, good in anti-wrinkle effect, excellent in washability, water-based and environment-friendly, and can meet environmental protection requirements of export.

Description

technical field [0001] The invention relates to the technical field of after-finishing of textile fabrics, in particular to a water-based imitation coating high-elastic and crisp finishing agent and a preparation method thereof. Background technique [0002] At present, most of the high-elasticity and crisp finishing agents for fabrics on the market are completed by solvent-based silicone high-elasticity coating adhesives, which are deeply loved by customers because of their excellent high-elasticity, crispness, and smooth unique handle style. But the disadvantage is that the unique hand feeling of the coated fabric will be seriously reduced after washing, and 70% to 80% of the solvent glue is solvent toluene. Improper operation is prone to fire or explosion, resulting in loss of personnel and property. [0003] The patent with publication number CN102926212A discloses a water-based high-elastic coating adhesive for cotton and linen fabrics and a preparation method thereof....
