Abstract

The invention relates to a water-based fabric coating finishing agent with thermal insulation performance. The water-based fabric coating finishing agent is prepared from 40-60 parts of waterborne polyurethane emulsion, 10-20 parts of polypropylene resin emulsion, 4-6 parts of thickening agent, 30-40 parts of deionized water, 5-10 parts of organic silicon emulsion, 8-10 parts of titanium dioxide, 10-20 parts of silicon dioxide aerogel subjected to surface treatment, 3-6 parts of titanium dioxide dispersing agent, 4-8 parts of silicon dioxide aerogel dispersing agent, 2-5 parts of silane coupling agent and 1-2 parts of wetting agent. The water-based fabric coating finishing agent meets the environment-friendly requirement, and the finished fabric has good heat retention property, friction resistance and washing resistance.

Description

technical field [0001] The invention belongs to the field of finishing agents for textiles, in particular to a water-based fabric coating finishing agent with heat-retaining performance. Background technique [0002] Keeping warm is the primary consideration of human beings in winter. Making fabrics with heat-retaining properties is an important direction for the textile industry to explore. Traditional heat-retaining fabrics improve heat-retaining properties by adding fillers or fabric thickness. Consequently, the resulting product is heavier and less comfortable. At present, the research and development of the thermal insulation performance of the fabric itself has limited effects and cannot achieve a better thermal insulation function. In the prior art, there are many ways to keep warm by compounding multi-layer fabrics, but the process is complicated and the cost is high. There is also improved thermal insulation by designing the fabric structure, but the weaving proce...
