Abstract

The invention discloses a windproof, cold-resistant and color fasting aqueous coating adhesive for a textile fabric and a preparation method. The preparation method comprises the following steps: carrying out condensation on 100-150 parts of end epoxy silicon oil, 3-9 parts of polyether amine and 15-30 parts of isopropanol, adding 1-2 parts of polyethyl silicate-40, 12-20 parts of isotridecanol polyoxyethylene ether, 1-2 parts of glacial acetic acid and 220-340 parts of softening water for emulsification, and further mixing and thickening with 70-110 parts of a hydroxyl-ended epoxy modified polysiloxane emulsion, 260-440 parts of an anionic polyurethane emulsion, 10-30 parts of an aqueous sealed isocyanate cross-linking agent and 10-20 parts of an associated alkali swelling thickening agent, thereby obtaining a product. A fabric finished with the adhesive is excellent in wind resistance and cold resistance, is soft and smooth in hand feeling and good in rebound resilience, and has airpermeability being 10 mm / s or lower and cold resistance up to minus 30 DEG C; in addition, the friction color fastness of a colored fabric can be improved by 0.5-1.5 degrees.

Description

technical field [0001] The invention relates to the finishing technology of textile fabrics, in particular to a windproof, cold-resistant, color-fixing water-based coating glue for textile fabrics and a preparation method. The coating adhesive is mainly composed of amino polyether modified polyorganosiloxane, hydroxyl-terminated epoxy modified polyorganosiloxane, crosslinking agent, anionic polyurethane emulsion, and can be used for polyester, nylon, pure cotton and their blends Multi-functional finishing of fabrics. After finishing, the air permeability of the fabrics can be less than 10mm / s, the cold resistance can reach -30℃, and the color fastness to rubbing of dyed fabrics can be improved by 0.5-1.5 grades. Background technique [0002] The wind resistance of fabrics is usually evaluated by air permeability, which is expressed by the rate at which airflow passes through the fabric vertically under the specified fabric area, pressure drop and time conditions. The cold r...
