Embodiment 1

[0018] A manufacturing method of waterproof fabric includes the following steps:

[0019] (1). Treat the dyed and dried cotton cloth in a constant temperature and humidity box at 20°C and 70RH for 3 hours, then perform corona treatment, and treat it under 6kV for 7 seconds;

[0020] (2) After the corona treated textile is immersed with amino silicone waterproofing agent for 2s, it is double-dipped and double-rolled, with a surplus rate of 60%, and dried at 100°C for 4 minutes to obtain a soft and waterproof textile.

[0021] The preparation method of the amino organosilicon waterproof treatment agent is:

[0022] a. 0.3mol of octamethylcyclotetrasiloxane and 1mol of tetravinyltetramethoxycyclotetrasiloxane are distilled under reduced pressure under the condition of 0.75MPa to remove low boiling substances, and then 1mol of N-β is added -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and 0.001mol potassium hydroxide, reacted at 130℃ for 10h under normal pressure, then heated to 160℃, ...

Embodiment 2

[0025] A manufacturing method of waterproof fabric includes the following steps:

[0026] (1) Treat the dyed and dried polyester in a constant temperature and humidity box at 25°C and 60RH for 4 hours, and then perform corona treatment and treat it under 9kV for 3 seconds;

[0027] (2) After the corona treated textile is immersed with amino silicone waterproofing agent for 3 seconds, it is double-dipped and double-rolled, with a surplus rate of 65%, and dried at 120°C for 2 minutes to obtain a soft and waterproof textile.

[0028] The preparation method of the amino organosilicon waterproof treatment agent is:

[0029] a. 0.3mol of octamethylcyclotetrasiloxane and 1mol of tetravinyltetramethoxycyclotetrasiloxane were distilled under reduced pressure under the condition of 0.75MPa to remove low boiling substances, and then 2molN-β was added -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and 0.003mol potassium hydroxide, reacted at 150℃ for 7h under normal pressure, then heated to 160...

Embodiment 3

[0032] A manufacturing method of waterproof fabric includes the following steps:

[0033] (1) Treat the dyed and dried nylon in a constant temperature and humidity box at 28°C and 60RH for 4 hours, then perform corona treatment, and treat it under 10kV for 4 seconds;

[0034] (2) After the corona treated textile is immersed in amino silicone waterproofing agent for 5 seconds, it is double-dipped and double-rolled, with a surplus rate of 70%, and dried at 130°C for 1 minute to obtain a soft and waterproof textile.

[0035] The preparation method of the amino organosilicon waterproof treatment agent is:

[0036] a. 0.3mol of octamethylcyclotetrasiloxane and 1mol of tetravinyltetramethoxycyclotetrasiloxane are distilled under reduced pressure at a pressure of 0.75MPa to remove low-boiling substances, and then 3molN-β -(Aminoethyl)-γ-aminopropylmethyldimethoxysilane and 0.003mol potassium hydroxide, reacted at 140℃ for 8h under normal pressure, then heated to 160℃, maintained at 0.75MPa a...

Abstract

The invention discloses a manufacturing method of a waterproof braided fabric. The method comprises the following steps: performing corona treatment on the fabric, then soaking the fabric in an amino organic silicon waterproof treatment agent, and drying the fabric to obtain the soft fabric with a waterproof function. Compared with the prior art, the pH of the prepared waterproof agent is adjusted to 5.5 to 6.5, and amino groups are converted to ammonium salt groups under an acidic condition, so that the amino organic silicon waterproof agent is positively charged and is more likely to adsorb on the surface of the fabric which is negatively charged, and the softness of the fabric and the firmness of a waterproof membrane can be improved; in the emulsification process, a stirring emulsification way for adding the distilled water for multiple times is adopted, the particle size of the emulsion is smaller and more stable, and the emulsion is easier and more uniformly adsorbed on the surface of the fabric to form a membrane; after the corona treatment, hydroxyl, carboxyl, epoxy groups and active groups of peroxide are generated on the surface of the fabric, and the groups with negative charge on the surfaces are increased, so that the fabric is more effectively combined with the amino organic silicon waterproof treatment agent, and the water resistance, softness and combination firmness of the fabric can be improved.

Description

Technical field [0001] The invention relates to the textile field, in particular to a method for manufacturing a waterproof fabric. Background technique [0002] With the improvement of people's living standards, clothes are not only required to cover the body to keep out the cold, but also to be comfortable, with moisture permeability, waterproof and other functions. In order to realize these functions, the fabrics must be treated when the fabrics are produced, and the fabrics must be treated with fabric finishing agents to achieve the desired functions. [0003] When clothes are required to have waterproof function, it is necessary to treat textiles with waterproofing agents. The commonly used fabric waterproofing finishing agent is silicone waterproofing agent. However, textiles treated with traditional silicone waterproofing agents are not soft enough, and after being made into clothes, their softness cannot meet the requirements. Summary of the invention [0004] In order to ...
