Abstract

The invention discloses a washable fabric heat insulation coating, and belongs to the technical field of dyeing and finishing auxiliaries. By weight, 50-60 parts of polyurethane, 60-80 parts of N,N-dimethylformamide, 20-25 parts of a heat insulation filler, 2-3 parts of a dispersing agent, 2-4 parts of a defoaming agent and 1-3 parts of a bactericide are sequentially weighed; the polyurethane andthe N,N-dimethylformamide are mixed in a stirrer, the heat insulation filler, the dispersing agent, the defoaming agent and the bactericide are added into the stirrer, and the washable fabric heat insulation coating is obtained after stirring and mixing are conducted for 1-2 h under the conditions that the temperature is 20-40 DEG C and the rotation speed is 600-800 r / min. The obtained washable fabric heat insulation coating has excellent heat insulation performance and water washing resistance, and the heat insulation performance is not easily reduced after friction washing.

Description

technical field [0001] The invention discloses a washable heat-insulating coating for fabrics, which belongs to the technical field of dyeing and finishing auxiliaries. Background technique [0002] Washable fabric thermal insulation coating refers to coating the coating with thermal insulation function on the surface of the fabric, which can reduce the temperature inside the fabric covering by inhibiting the temperature rise of the coating surface, and play the role of thermal insulation and cooling. In the textile industry, it can be coated on the surface of the tent to solve the problem that the internal temperature of the tent is high in hot weather and affect work and rest; it can also be coated on the curtains to solve the problem of excessive indoor temperature under strong sunlight. problem; if coated on clothing, it can solve the physical discomfort of workers in high temperature environments. In addition, according to the needs of use, it can also be coated on car...
