Problems solved by technology

At present, the plasticizers added in the middle layer PVC plastic of the existing PVC stiff composite cloth are all harmful chemical substances, such as carcinogenicity, endocrine disorder, and reproductive toxicity.
The PVC stiff composite cloth produced by the existing PVC stiff composite cloth production process has the following disadvantages: on the one hand, it has poor high temperature resistance, and substances harmful to the environment will be produced during the production process, which is not environmentally friendly; on the other hand , the surface of the prepared PVC stiff composite cloth is prone to stains such as yellow marks, and the surface color is yellowish, which is not beautiful enough, which leads to a high defect rate and increases the cost of the PVC stiff composite cloth manufacturer.

Embodiment 1

[0014] A kind of environment-friendly composite cloth preparation process, comprises the following steps:

[0015] 1) Immerse the cloth in the clean water in the cleaning tank, add an appropriate amount of oxalic acid to the cleaning tank, and the temperature of the cleaning water is 100°C;

[0016] 2) After cleaning, rinse the fabric to clean the oxalic acid residue in the fabric; 3) Take out the rinsed fabric, de-dry it first, then dry it, and after cooling, set it in a tenter; 4) Put the polyvinyl chloride resin , calcium carbonate, polyethylene glycol, PVC stabilizer, environmental plasticizer and organotin stabilizer are put into the mixer and stirred for 15-25 minutes to make it into a paste slurry;

[0017] 5) Put the slurry in a room temperature room at 20°C for 90 hours;

[0018] 6) Apply the slurry evenly between the upper and lower layers of fabrics that have been processed from step 1) to step 3), and put them into a plastic scraping machine for rolling and drying...

Embodiment 2

[0020] A kind of environment-friendly composite cloth preparation process, comprises the following steps:

[0021] 1) Immerse the cloth in clean water in the cleaning tank, add an appropriate amount of oxalic acid to the cleaning tank, and the temperature of the cleaning water is 60°C;

[0022] 2) After washing, rinse the cloth to remove the oxalic acid residue in the cloth;

[0023] 3) Take out the rinsed fabric, de-dry it first, then dry it, and after cooling, set it into a stenter;

[0024] 4) Put polyvinyl chloride resin, calcium carbonate, polyethylene glycol, PVC stabilizer, environmental plasticizer and organic tin stabilizer into the mixer, and stir for 25 minutes to make it into a paste-like slurry;

[0025] 5) Place the slurry in a room temperature room at 40°C for 80 hours;

[0026] 6) Apply the slurry evenly between the upper and lower layers of fabrics that have been processed from step 1) to step 3), and put them into the plastic scraping machine for rolling an...

Abstract

The invention relates to an environment-friendly composite fabric preparation process. The environment-friendly composite fabric preparation process comprises the following steps: (1) soaking a fabric in clean water in a washing tank; (2) scouring the fabric after being washed, and cleaning oxalic acid residue on the fabric; (3) taking out the cleaned fabric; (4) placing polyvinyl chloride resin, calcium carbonate, poly(hexylene glycol), a PVC stabilizing agent, an environment-friendly plasticizer and an organic tin stabilizer into a stirrer; (5) placing a sizing agent for 20 to 90 hours in a normal-temperature room at the temperature of 20 to 60 DEG C; (6) uniformly smearing the sizing agent between an upper layer fabric and a lower layer fabric, rolling at a high temperature, drying, and finally obtaining a finished product. An article for labor protection, produced by the composite fabric, is not only soft and comfortable to wear, but also has the advantages of acid and alkali resistance, high temperature resistance, high strength and reliable safety performance. The production process flow is reasonable in design, the operation is simple and convenient, and the cost is low. The environment-friendly composite fabric preparation process can be applied to other textile fabric markets, is wide in application prospect and is worthy of being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of composite cloth, in particular to a preparation process of an environment-friendly composite cloth. Background technique [0002] The composite cloth is coated with a plastic layer containing PVC between two layers of cloth to make the surface smoother, better waterproof, and has excellent mildew resistance, good low-temperature softness, high strength, strong tensile force, and relatively light Features. At present, the plasticizers added in the middle layer PVC plastic of the existing PVC stiff composite cloth are all harmful chemical substances, such as carcinogenicity, endocrine disorder, and reproductive toxicity. The PVC stiff composite cloth produced by the existing PVC stiff composite cloth production process has the following disadvantages: on the one hand, it has poor high temperature resistance, and substances harmful to the environment will be produced during the production process, which is ...
