Embodiment 1

[0029] A method for producing a microporous dry-process waterproof and moisture-permeable fabric, which comprises the following steps:

[0030] 1. According to the weight ratio, 60 parts of polyurethane microporous resin, 5 parts of dimethylformamide (DMF), and 30 parts of toluene (TOL) are blended into a slurry as a fabric, and a certain amount of polyester is scraped out with a certain scraper gap. The number of layers is coated on the release paper, and then enters the oven for drying. The oven temperature is 100-130°C, the line speed is 13-14m / min, and the coating material is 150g / y.

[0031] 2, the polyurethane that is 60 parts by weight, the dimethylformamide of 5 parts, the toluene of 40 parts, the accelerator SA-90H of 2 parts, the bridging agent (502) of 8 parts, deploy into slurry, as The base material is coated on the release paper in the above step 1 with an appropriate number of polyester cloth (using the gap between the scraper), and then enters the oven to dry u...

Embodiment 2

[0035] 1. 100 parts by weight of polyurethane microporous resin, 10 parts of dimethylformamide (DMF), and 40 parts of toluene (TOL) are prepared into a slurry as a fabric, and coated with an appropriate number of polyester layers on the release paper, and then enter the oven for drying, wherein the oven temperature is 100-130°C, the line speed is 13-14m / min, and the coating material is 150g / y.

[0036] 2, be 100 parts of polyurethane by weight, 10 parts of dimethylformamide, 50 parts of toluene, 3 parts of promotor SA-90H, 10 parts of bridging agent (502), mix into slurry, as The base material is coated on the release paper of the above step 1 with an appropriate number of polyester cloth, and then enters the oven and bakes until it is 70% dry, and the required cloth is compounded by rolling, wherein the oven temperature is 100°C, and the line speed is 13- 14m / min, coating material 150g / y.

[0037] 3. After the compounded product is completely dried from the oven, the cloth a...

Embodiment 3

[0039] 1. 80 parts by weight of polyurethane microporous resin, 7 parts of dimethylformamide (DMF), and 35 parts of toluene (TOL) are prepared into a slurry as a fabric, and coated with an appropriate number of polyester layers on the release paper, and then enter the oven for drying, wherein the oven temperature is 100-130°C, the line speed is 13-14m / min, and the coating material is 150g / y.

[0040] 2, be 75 parts of polyurethane by weight, 8 parts of dimethylformamide, 45 parts of toluene, 2 parts of accelerator SA-90H, 10 parts of bridging agent (502), allotted into slurry, as The base material is coated on the release paper of the above step 1 with an appropriate number of polyester cloth, and then enters the oven and bakes until it is 70% dry, and the required cloth is compounded by rolling, wherein the oven temperature is 100°C, and the line speed is 13- 14m / min, coating material 150g / y.

[0041] 3. After the compounded product is completely dried from the oven, the clo...

Abstract

The invention discloses a micro porous dry-method waterproof and moisture-permeable fabric and a production method thereof. The fabric can be used for outdoor functional sportswear, brand readymade clothes, jackets, sport shoes, bedding and the like. The production method comprises the following steps of: uniformly coating a moisture-permeable fabric and a waterproof backing material on release paper in sequence; giving grains by rolling compound base fabrics through a transfer method; and volatilizing non-solvents and solvents in the fabric and the backing material at different degrees by baking with an oven at different degrees to make the fabric have the waterproof and moisture-permeable functions. The fabric produced by the method overcomes the defect of poor water-resisting property because the conventional hydrophilic imporous thin film fabric swells when wet, has good moisture permeability and hydraulic pressure performance and widens applied range of the waterproof and moisture-permeable fabric.

Description

technical field [0001] The invention discloses a microporous dry-process waterproof and moisture-permeable fabric and a production method thereof, which belong to the technical field of waterproof and moisture-permeable fabric manufacturing technology, and in particular is a microporous dry-process waterproof and moisture-permeable fabric prepared by using the principle of moisture permeability, which can be widely used For outdoor functional sportswear, branded ready-to-wear, jackets, sneakers, bedding, etc. Background technique [0002] Nowadays, with the improvement of living standards, people pay more attention to health. As a healthy and fashionable way of leisure, outdoor sports are becoming more and more popular, and outdoor clothing has also made great progress. Compared with ordinary clothing, outdoor sports clothing emphasizes some special functions, such as waterproof, moisture permeability, windproof, and warmth, while focusing on comfort. [0003] Waterproof an...
