Problems solved by technology

[0005] However, due to the shorter carbon chain of C6-type fluororesin, the hydrophobic and waterproof effects of textiles treated with C6-type fluororesin are lower than those of C8-type
Especially in the application of superfine fiber suede artificial leather, because the polyurethane resin in superfine fiber suede artificial leather has strong hydrophilicity, the superfine fiber suede artificial leather treated with ordinary C6 fluororesin Hydrophobicity and water resistance are generally poor and cannot meet the requirements

Embodiment 1

[0023] Polyester microfiber base fabric, the fiber used is 37 islands and islands, the sea component is polyester, the island component is polyester, and the length is 51mm. The above-mentioned fibers are laid and needle-punched to prepare the base cloth. The base fabric is subjected to heat shrinkage to increase the apparent density and then impregnated with water-based polyurethane resin. After the impregnated treatment, the part of the sea is removed by solidification and lye solution, and finally sanded, dyed, and finished to obtain the semi-finished artificial leather. Carry out hydrophobic post-treatment to above-mentioned artificial leather semi-finished product.

[0024] The specific prescription is as follows:

[0025] 1. Daikin TG-5601 50g / L (Daikin)

[0026] 2. Blocked isocyanate 5g / L (Nikka Chemical)

[0027] 3. Water-soluble melamine-formaldehyde resin 30g / L (Nikka Chemical)

[0028] 4. Catalyst 10g / L (Nikka Chemical)

[0029] The artificial leather semi-fini...

Embodiment 2

[0031] Nylon microfiber base fabric, the fiber used is 37 islands, the sea component is polyester, the island component is nylon, and the length is 51mm. Subsequent processing is the same as in Example 1.

Embodiment 3

[0033] The same base fabric as in Example 1 was used.

[0034] The prescription for hydrophobic post-treatment is as follows:

[0035] 1. Daikin TG-5601 80g / L (Daikin)

[0036] 2. Blocked isocyanate 8g / L (Nikka Chemical)

[0037] 3. Water-soluble melamine-formaldehyde resin 20g / L (Nikka Chemical)

[0038] 4. Catalyst 10g / L (Nikka Chemical)

[0039] The artificial leather semi-finished product is impregnated in the above-mentioned aqueous solution and then dried, followed by heat treatment. The temperature of the heat treatment is 130 degrees, and the treatment time is 2 minutes.

Abstract

The invention discloses superfine fiber suede artificial leather with a waterproof function and a manufacturing method thereof and belongs to the technical field of producing and processing of superfine fiber suede artificial leather. The manufacturing method includes: subjecting a semifinished superfine fiber suede artificial leather product to hydrophobic aftertreatment which uses C6 fluroplast resin as a water reducer and closed isocyanate, water-soluble melamine-formaldehyde resin and a catalyst of the water-soluble melamine-formaldehyde resin as additives, and forming a firm waterproof layer on the surface of the semifinished superfine fiber artificial leather product through impregnation and thermal treatment. Through the manufacturing method, the superfine fiber suede artificial leather having high hydrophobicity, waterproofness and weatherability can be manufactured.

Description

technical field [0001] The invention discloses a superfine fiber suede artificial leather with waterproof function and a manufacturing method thereof, belonging to the technical field of production and processing of superfine fiber suede artificial leather. Background technique [0002] At present, most of the superfine fiber suede artificial leather produced at home and abroad is made of sea-island superfine fiber, which is opened, carded, formed into a web, and then repeatedly consolidated by a needle (or spunlace) machine to become a gray cloth. Then go through polyurethane padding, solidification, lye (or solvent) to dissolve (or extract) the part of the sea, and finally go through sanding, dyeing, and finishing to get the finished product. [0003] The suede artificial leather prepared by the above method has been widely used in clothing, bags, decorative materials and automotive interiors. And according to different uses, the requirements for various properties of mic...
