Abstract

The invention relates to a durable flame-retardant, water-repellent, waterproof and moisture permeable finishing method of a polyester fabric. A flame-retardant and water-repellent finishing agent is prepared from 20-30 parts of cyclic phosphate flame retardants, 60-70 parts of water, 1-1.5 parts of isocyanate cross-linking agents, 3-5 parts of fluorocarbon copolymer waterproof agents and 2-5 parts of NaOH with 10% mass concentration. A bottom coating adhesive is prepared from 100 parts of polyether polyurethane polymer under-coating adhesives, 5-10 parts of methylbenzene, 5-10 parts of butanone, 2 parts of isocyanate cross-linking agents, 1 part of accelerant and 25-35 parts of organic phosphorus-nitrogen flame retardants. A surface coating adhesive is prepared from 100 parts of polyether polyurethane polymer top-coating adhesives and 35-45 parts of methylbenzene. The fabric is padded, calendered, under-coated and top-coated with water repellents to achieve finishing by the flame-retardant and water-repellent finishing agent, the bottom coating adhesive and the surface coating adhesive.

Description

technical field [0001] The invention relates to a finishing technology for textile fabrics. Especially suitable for polyester filament Oxford cloth. It specifically relates to a finishing method for durable flame-retardant, water-repellent, waterproof and moisture-permeable coatings on polyester fabrics. Background technique [0002] Polyester is the world's largest output and most widely used synthetic fiber variety, accounting for more than 60% of the world's synthetic fiber output. It is widely used in textiles such as clothing, bedding, various decorative fabrics, special fabrics for national defense and military industries, and other industrial fiber products. Due to the characteristics of polyester fabric synthetic materials, it is very flammable, so the development of polyester flame-retardant fabrics is extremely important. [0003] Patent CN103469603A "A Flame Retardant Finishing Method for Polyester Fabrics" discloses a flame retardant finishing process for polye...
