Abstract

The invention discloses a formula and a process of organosilicone water repellent finish. The formula is characterized in that the padding liquid raw material composition is as follows: 8-12g / L of zinc acetate, 5.5-5.9g / L of zirconium oxychloride, 33-38g / L of methyl hydrogen-containing silane emulsion, 20-23g / L of epoxidized aminate cross-linker, 72-75g / L of hydroxyl silane emulsion and 5-6g / L of monoethanolamine. A fabric has a good and washable water-repellent performance, and moreover, the tearing strength, hand feeling and sewing performance of the fabric can be obviously improved.

Description

technical field [0001] The invention relates to a formula and process for organosilicon water-repellent finishing. Background technique [0002] Water-repellent finishing is a finishing process that uses chemical water-repellent agents to form a water-repellent surface on fibers. Organosilicon is a washable and water-repellent finishing agent based on linear hydrogen-containing polymethylsiloxane developed in the 1950s, and its reaction performance is relatively active. In application, the organic silicon water-repellent finishing agent and catalysts such as zinc octylate or titanium organic compound are formulated into emulsion padding fabrics, dried and baked at 150°C for several minutes, and then washed with water. During the curing process, the hydromethicone forms a polymer network on the fibers. The methyl groups are arranged vertically and densely on the surface of the fiber, which makes the fabric have good and washable water repellency. This type of water repelle...
