Embodiment 1

[0017] A coating method for a modified coating that improves coating weight:

[0018] 1. Preparation of silk fibroin solution:

[0019] Place the silk fiber in a sodium carbonate solution with a mass concentration of 0.5%, add distilled water whose volume is 100 times that of the sodium carbonate solution, and bathe in boiling water for 30 minutes. After the above operation has been repeated twice, wash the silk fiber with distilled water to obtain pure silk fibroin. Shred after drying at 50°C. Prepare a calcium chloride:ethanol:water ternary system with a molar ratio of 1:2:8, heat and stir in a water bath at 75°C, and then add chopped pure silk fibroin in batches until completely dissolved to obtain The crude brown silk fibroin solution is dialyzed with deionized water, filtered and concentrated to obtain a silk fibroin solution, which is put into a refrigerator for later use.

[0020] 2. Preparation of silk fibroin solution modified coating glue:

[0021] The amount of s...

Embodiment 2

[0025] A coating method for a modified coating that improves coating weight:

[0026] 1. Same as Step 1 of Example 1.

[0027] 2. Same as Step 2 of Example 1.

[0028] 3. Take the modified coating glue in step 2 to coat the polyester fabric, and control the coating amount to 9.6g.cm -2 , baked at 150°C for 2 minutes, and tested the waterproofness, moisture permeability and physical and mechanical properties of the coated fabric.

[0029] Test results: The hydrostatic pressure of the modified coated fabric is 808mm, and the moisture permeability is 706g.(m 2 .d) -1 , ISO whiteness 72.8%, abrasion resistance 115R, breaking strength 332N, breaking elongation 34.0mm. It was found that by adjusting the coating amount, the waterproofness and moisture permeability of the coated fabric were balanced, and the physical and mechanical properties of the coated fabric were not affected.

Embodiment 3

[0031] A coating method for a modified coating that improves coating weight:

[0032] 1. Same as Step 1 of Example 1.

[0033] 2. Same as Step 2 of Example 1.

[0034] 3. Take the modified coating glue in step 2 to coat the polyester fabric, and control the coating amount to 16.3g.cm -2 , baked at 150°C for 2 minutes, and tested the waterproofness, moisture permeability and physical and mechanical properties of the coated fabric.

[0035] Test results: The hydrostatic pressure of the modified coated fabric is 953mm, and the moisture permeability is 696g.(m 2 .d) -1 , ISO whiteness 71.7%, abrasion resistance 122R, breaking strength 306N, breaking elongation 33.5mm. It was found that by adjusting the coating amount, the waterproofness and moisture permeability of the coated fabric were balanced, and the physical and mechanical properties of the coated fabric were not affected.

Abstract

The invention discloses a coating method of a modified coating for improving coating weight. The coating method comprises the following steps: preparing a fibroin solution with the solid content of 36.2g.L<-1> by taking silk fiber as a material and adopting a ternary system containing calcium chloride, ethanol and water to dissolve fibroin; mixing the fibroin solution with a formaldehyde-free crosslinking agent at first, then adding a waterborne coating adhesive, adding a polyurethane thickener, stirring for dispersion, coating a polyester fabric, controlling the coating amount, baking at 150 DEG C for 2 minutes, and detecting the moisture permeability, water resistance and physical and mechanical properties of a coated fabric, wherein 10g of the waterborne coating adhesive is added, the used amount of the fibroin solution is 3% of the mass of the waterborne coating adhesive, and the used amount of the formaldehyde-free crosslinking agent is 3% of the mass of the waterborne coating adhesive. Compared with the prior art, by adopting the coating method disclosed by the invention, the water resistance and moisture permeability of the coated fabric are balanced, and the physical and mechanical properties of the coated fabric are not influenced.

Description

technical field [0001] The invention relates to the field of textile chemical industry, in particular to a coating method of a modified coating which improves the coating amount. Background technique [0002] Fabric coating, as the name suggests, is to coat a layer of other materials on the surface of the fabric. This also shows that fabric coating has two processing objects - base fabric, coating material, and a technology that combines the two - coating technology. Coating technology in a broad sense also includes lamination, that is, applying a layer of adhesive on the base cloth, covering it with a layer of film or other materials, heating and pressing to form a composite fabric; or the film itself is the adhesive material, Bond the base fabric with other materials. In a narrow sense, it is the process of scraping the coating material onto the surface of the fabric. The coating method of the fabric coating should be selected according to the product requirements and t...
