Problems solved by technology

[0004] At present, most of the jacket fabrics at home and abroad are solvent-based waterproof and moisture-permeable polyurethane coating adhesive-coated products. The produced fabrics have good waterproof, moisture-permeable and water-resistant properties, but because the production process is not environmentally friendly and there are residual toluene, Organic solvents such as DMF and methyl ethyl ketone are harmful to human health. Therefore, the jacket fabrics finished with water-based waterproof and moisture-permeable polyurethane coatings have been extensively studied by researchers, but there are no relevant literature reports that are relatively mature and suitable for middle-weight jackets. processing method

Abstract

The production and treatment method of the durable antistatic, friction-resistant, waterproof and moisture-permeable, anti-seepage outerwear fabrics, (1) use 20-30g / L C8 fluorine-based waterproof finishing liquid to carry out water-repellent finishing on 70D nylon or 75D polyester fabrics, two dips Two calendering, pre-baking-baking; (2) calendering finishing, (3) dry coating of fabrics with coating glue, dry weight gain 25-30g / m 2 , the coating glue is made of water-based waterproof and moisture-permeable polyurethane adhesive 80-100, water 5-15, graphene oxide sol 5-10, PTFE powder 2-4, blocked isocyanate crosslinking agent 5-10 . It is especially suitable for 70D nylon and 75D polyester fabrics. After production and treatment, the products have excellent antistatic, friction resistance, waterproof and moisture permeability, water seepage resistance, and water washing resistance. The production process is short, environmentally friendly, and easy to operate.

Description

technical field [0001] The present invention relates to textile post-finishing technology, and specifically relates to a treatment method for polyester and nylon fabrics to process jacket fabrics with durable antistatic, friction resistance, waterproof and moisture permeability, and water seepage resistance. Contains organic volatile gases and is an environmentally friendly product. Background technique [0002] The so-called "jacket fabric" in the industry is a fabric with waterproof, moisture-permeable, and water-resistant properties. Therefore, it is defined as "jacket fabric" to distinguish it from other fabrics; it is classified into coating and lamination according to its processing method. There are two methods of production; according to the scope of use, there are middle-weight jackets and ultra-light jackets. The fabrics of middle-weight jackets are mostly 70D nylon and 75D polyester fabrics, which are used for outdoor sports such as mountaineering and hiking. They...
