Embodiment 1

[0029] Made of polyester silk fabric, unwound for waterproofing. In the waterproof treatment liquid, 100 grams of soft water, 2 grams of fluorine-based waterproofing agent AG-480, 1 gram of isopropanol, and acetic acid is added to adjust the pH to 6. Then bake the impregnated cloth base at 140° C., dry for 3-5 minutes, and then wind up. Next, a wet film-forming process is performed. Unwind the waterproof treated cloth base, and coat the first layer of PU mixture, in which 100 grams of PU resin M-498, 30 grams of DMF, 1 gram of fluorine surface modifier F-3D, 1 gram of silicon dioxide, bridging Agent WD-40 2 g. After the coating is completed, solidify at room temperature for 8 seconds, and then iron it at 80°C. After ironing, apply the second layer of PU mixture, including 100 grams of PU resin M-498, 35 grams of DMF, 1 gram of fluorine surface modifier F-3D, 1 gram of accelerator S-901, and an appropriate amount of color paste (pigment). After coating, solidify for 3 minut...

Embodiment 2

[0031] Use polyester silk fabric, unwind for waterproof treatment, waterproof treatment solution, 100 grams of soft water, 4 grams of fluorine-based waterproofing agent YD-510A, 3 grams of isopropanol, add acetic acid to adjust the pH to 5. Then bake the impregnated cloth base at 160° C., dry for 3-5 minutes, and then wind up. Then carry out the wet film forming process, unwind the waterproof treated cloth base, and coat the first layer of PU mixed solution, wherein 100 grams of PU resin M-825, 40 grams of DMF, 3 grams of fluorine surface improver F-3D, 2 grams of silicon dioxide, 5 grams of bridging agent AD-8. After the coating is completed, solidify at room temperature for 10 seconds, and then iron it at 110°C. After ironing, apply the second layer of PU mixture, in which 100 grams of PU resin M-825, 40 grams of DMF, 3 grams of fluorine surface modifier F-3D, 2 grams of accelerator S-92, and appropriate amount of color paste (pigment). After coating, solidify for 5 minute...

Embodiment 3

[0033] Use polyester silk fabric, unwind for waterproof treatment, in the waterproof treatment solution, soft water is 100 grams, fluorine-based waterproofing agent SG-713 6 grams, isopropanol 4 grams, and glacial acetic acid is added to adjust the pH to 5. Then bake the impregnated cloth base at 180° C., dry for 3-5 minutes, and then wind up. Then carry out the wet film forming process, unwind the waterproof treated cloth base, and coat the first layer of PU mixed solution, wherein PU resin M-826 is 100 grams, DMF50 grams, fluorosurfactant F-3D 5 grams, 4 grams of silicon dioxide, 8 grams of bridging agent AD-7. After the coating is completed, solidify at room temperature for 15 seconds, and then iron it at 130°C. After ironing, apply the second layer of PU mixture, wherein 100 grams of PU resin M-826, 45 grams of DMF, 5 grams of fluorine surface modifier F-3D, 4 grams of accelerator S-92, and appropriate amount of color paste (pigment). After coating, solidify for 5 minute...

Abstract

The production process of polyurethane coating cloth includes the waterproof the of base cloth, wet painting to form film, printing or post-painting treatment and inspection. The wet painting to form film includes twice painting polyurethane mixture liquid, solidifying to form film, water washing and ironing; stoving; cooling and winding and forms microporous film. The composite polyurethane coating structure has in its inside micro pores of diameter between water drop diameter and water molecule owing to the replacement of water and DMF and the special micro pore regulating effect during the twice water washing. The present invention can meet the requirement of resisting water, resisting cold, permeating moisture and being light for easy carrying about.

Description

technical field [0001] The invention relates to a coated cloth clothing fabric, in particular to a polyurethane (PU) coated cloth and a production process thereof. Background technique [0002] Polyurethane coated cloth is mainly used to make military clothing, mountaineering, skiing and various tourist sportswear. At present, the waterproof and cold-proof synthetic leather clothing fabrics on the market have no moisture-permeable function, and the fabrics are very heavy, which is difficult to meet the requirements of the military and tourists for special functions such as clothing waterproof, cold-proof, and moisture-permeable. The development of new waterproof, cold-proof, and moisture-permeable clothing fabrics and the improvement of related processes are current problems to be solved. Contents of the invention [0003] The object of the present invention is to provide a multi-functional polyurethane coated cloth integrating waterproof, cold protection, moisture permea...
