Abstract

The invention discloses a production process for a waterproof shell fabric. The production process comprises the following steps: (1) preparing first slurry; (2) coating the surface of base cloth with the first slurry; (3) drying at 100 DEG C for 5-7 minutes; (4) mixing following components in parts by mass: 1-2 parts of lauryl aminoethyl sodium sulfate, 130 parts of polyurethane resin, 5-6 parts of 1,6-diisocyanatohexane, 60-65 parts of water, 17-19 parts of butanone, 6-7 parts of N-methylethanolamine and 40-45 parts of toluene; sieving with a nylon net with the size of 200 meshes; standing for 75 minutes under a vacuum condition to prepare second slurry; (5) coating the upper surface of a bottom coating with the second slurry to form a middle coating; (6) drying at 120 DEG C for 3-4 minutes; (7) preparing third slurry; (8) coating the upper surface of the middle coating with the third slurry to form a surface coating; (9) drying at 110 DEG for 2-3 minutes. According to the production process for the waterproof shell fabric, the moisture permeability of a textile is improved under the condition of guaranteeing the waterproof performance.

Description

technical field [0001] The invention relates to a production process of waterproof fabric. Background technique [0002] The moisture permeability of waterproof fabrics currently on the market is not very good. It is necessary for water not to soak into the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside world through the fabric in the form of water vapor, so as to avoid sweat accumulation and condensation between the body surface and the fabric, so as to maintain the comfort of the clothing. Contents of the invention [0003] The purpose of the present invention is to provide a production process for waterproof fabrics, which improves the moisture permeability of the fabric itself while ensuring the waterproof performance. [0004] In order to achieve the above object, the technical solution of the present invention is to design a production process of waterproof fabric, comprising the following steps: [0005] ...
