Embodiment 1

[0027] A processing technology for waterproof fabrics, comprising the steps of:

[0028] (1) Fabric pre-treatment: whitening and drying the fabric;

[0029] (2) Coating material preparation: according to the weight percentage, it includes the following components: 65% polyurethane, 8% anti-migration agent, 3.5% cocoic acid, 1.2% catalyst, and the rest is water;

[0030] (3) Immerse the whitened and dried fabric in the flame retardant for 2.5 hours at a temperature of 37°C;

[0031] (4) Dry and bake the impregnated fabric, wherein the drying temperature is 85°C and the time is 0.3 hours; the baking temperature is 210°C and the time is 1.8 hours.

Embodiment 2

[0033] A processing technology for waterproof fabrics, comprising the steps of:

Abstract

The invention discloses a processing technology for a waterproof fabric. The processing technology comprises the following steps of (1) pretreating a fabric, namely whitening the fabric, and drying; (2) preparing a coating material from the following components in percentage by weight: 60-70% of polyurethane, 5-10% of a migration inhibitor, 3-5% of an anionic penetrant, 1-3% of a catalyst and the balance of water; (3) dipping the whitened and dried fabric into the coating material prepared in the step (2); and (4) drying the dipped fabric, and then, baking. A certain quantity of polyurethane and the anionic penetrant are added into the coating material and are matched with the migration inhibitor to generate chemical reaction; due to the adoption of the migration inhibitor, the softness of the fabric can be effectively improved; and due to the adoption of the anionic penetrant, the surface activity of the coating material can be improved, so that the waterproofness of the coating can be favorably improved.

Description

technical field [0001] The invention relates to a processing technology of waterproof fabric, which belongs to the technical field of textile production. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the function of clothing fabrics. Existing fabrics usually do not have waterproof function, causing those workers who are often in contact with water to wet their clothes during work, which will not only affect their normal work, but also bring various problems to the workers themselves. inconvenient. Contents of the invention [0003] The technical problem solved by the present invention is to provide a processing technology for waterproof fabrics, which can make the processed fabrics have a waterproof function, and the garments made are suitable for wearing by workers who have been in contact with water for a long time, and can effectively waterproof function. [0004] In order to achieve the a...
