Abstract

The invention discloses a water-based imitation coating high-elasticity stiffening finishing agent and a preparation method, and relates to the technical field of textile fabric finishing. The finishing agent is prepared from the following raw materials in parts by weight: 50-60 parts of emulsion A, 100-120 parts of B, 5-10 parts of cationic blocked isocyanate crosslinking agent. A method for preparing a water-based imitation coating high-elasticity stiffening finishing agent. The epoxy-modified polyorganosiloxane emulsion A with high molar mass is cross-linked by amino polyether-modified polyorganosiloxane and polyethyl silicate. The reasonable compounding of the emulsion B prepared by the agent and the blocked isocyanate crosslinking agent, and the padding finishing of the fabric can significantly improve the elasticity and stiffness of the fabric, and achieve the effect of the coating process. The obtained finishing agent has good softness, good anti-wrinkle effect, excellent washing resistance, and is water-based and environmentally friendly, and can meet the export environmental protection requirements.

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-elasticity stiffening finishing agent and a preparation method. Background technique [0002] At present, most of the high-elasticity 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 unique feel style. However, the disadvantage is that the unique feel of the coated fabric will be seriously reduced after washing, and 70% to 80% of the solvent glue is solvent toluene. Improper operation is very likely to cause fire or explosion, resulting in loss of personnel and property. [0003] Patent Publication No. CN102926212A discloses a water-based high-elastic coating adhesive for cotton and linen fabrics and a preparation method thereof. The coating adhesive is ...
