Abstract

The invention discloses a highly-waterproof and highly-moisture-permeable fabric coating. The highly-waterproof and highly-moisture-permeable fabric coating comprises a PA glue layer and a PU glue layer, the PA glue layer comprises PA glue, a crosslinking agent and a solvent, the PU glue layer comprises PA glue, the crosslinking agent and the solvent, and a weight ratio of the PA glue to the PU glue is (20-40):100. The highly-waterproof and highly-moisture-permeable fabric coating has excellent waterproof property and excellent moisture permeability, and can resist hydrostatic pressure of 10000 mmH2O or above, and the moisture permeability B (JISL1099B-1) reaches 10000 g / m<2>.24hr. A coated fabric can be applied special places with high requirements of the waterproof property, the moisture permeability and the flame resistance; and the coating has the advantages of reasonable technology and low economic cost.

Description

technical field [0001] The invention relates to the field of textile technology, in particular to a highly waterproof and high moisture-permeable fabric coating and its process, and the invention also relates to the fabric coating process. Background technique [0002] At present, there are three main types of coatings for commonly used fabrics: PA coating: its main component is polyacrylate, which is a resin material with insufficient elasticity, but the cost is also low; PU coating: its main component is polyurethane, which feels softer. Soft, good elasticity, high cost; PVC coating: its main component is polyvinyl chloride, which feels hard and is less used now. [0003] Coating is a process in which the coating agent is directly coated on the fabric to form a continuous film, thereby changing the function of the coating surface. The coating agents used may be solution-type (solvent and water), emulsion-type, emulsion foam, plastisol or solvent-diluted plastisol. Direct...
