Abstract
The invention discloses a superfine fiber suede artificial leather with a waterproof function and a manufacturing method thereof, belonging to the technical field of production and processing of superfine fiber suede artificial leather. The finished product of the superfine fiber suede artificial leather with good hydrophobicity, water resistance and weather resistance can be prepared by the preparation method.
Description
Technical Field
The invention discloses superfine fiber suede artificial leather with a waterproof function and a manufacturing method thereof, belonging to the technical field of production and processing of superfine fiber suede artificial leather.
Background
At present, superfine fiber suede artificial leather produced at home and abroad is mostly made from sea-island superfine fiber as raw material, through opening, carding, web forming, repeated consolidation by a needling (or spunlace) machine to form grey cloth, then through polyurethane padding, solidification, alkali liquor (or solvent) dissolving (or extracting) sea parts, finally through sanding, dyeing and finishing, the finished product is obtained.
The suede artificial leather prepared by the above method has been widely used in clothing, bags, decorative materials, automotive interiors, and the like. And the requirements for various performances of the superfine fiber suede artificial leather are continuously increased according to different use purposes. Especially when applied to the aspects of clothes, cases, automobile interiors and the like, the superfine fiber suede artificial leather has higher requirements on waterproofness. The superfine fiber suede artificial leather with good hydrophobicity is prepared by post treatment, and has great market prospect.
Many domestic and foreign enterprises and scientific research departments carry out a lot of researches on the hydrophobic and waterproof treatment of general textiles, including the step of carrying out post-treatment on the textiles by using C8 type and C6 type fluororesins so as to enable the textiles to have the hydrophobic and waterproof effects. And treating the base fabric with a silicone compound to impart hydrophobicity thereto. The use of C8-type fluororesins is becoming narrower due to PFOA problems. On the other hand, the method for treating the base fabric by using the silicone compound is based on the principle that a coating layer is formed on the surface of the base fabric, and strong chemical force is not applied between the base fabric and the base fabric, so that the treatment method is only suitable for the application with low requirement on durability and weather resistance. Fluororesin C6 type is a hydrophobic treatment resin which is currently mainly used.
However, since the carbon chain of the fluororesin type C6 is short, the textile treated with the fluororesin type C6 has a lower water repellent and water repellent effect than the textile treated with the fluororesin type C8. Particularly, when the method is applied to the superfine fiber suede artificial leather, because the polyurethane resin in the superfine fiber suede artificial leather has stronger hydrophilicity, the hydrophobicity and the waterproofness of the superfine fiber suede artificial leather treated by the common C6 type fluororesin are generally poor, and the requirements cannot be met.
To solve this problem, the present inventors have solved the above-mentioned problems by screening and comprehensive comparison of various crosslinking agents. The scheme is generated.
Disclosure of Invention
In order to solve the problems, the invention provides superfine fiber suede artificial leather with a waterproof function and a manufacturing method thereof.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a manufacturing method of superfine fiber suede artificial leather with a waterproof function comprises the following steps of carrying out hydrophobic post-treatment on a superfine fiber suede artificial leather semi-finished product, wherein C6 fluorine resin is used as a waterproof agent in the hydrophobic post-treatment, blocked isocyanate, water-soluble melamine formaldehyde resin and a catalyst of the water-soluble melamine formaldehyde resin are added to be used as additives, and a firm waterproof layer is formed on the surface of the superfine fiber suede artificial leather semi-finished product through impregnation and heat treatment. That is, an aqueous solution for impregnation treatment of a C6 fluororesin was prepared in the present invention. In the aqueous solution for impregnation treatment of the C6 fluororesin, blocked isocyanate was a crosslinking agent, and a water-soluble melamine formaldehyde resin was a weather resistance improver.
As a further arrangement of the scheme, the usage amount of the C6 fluorine resin is 50g/L-200 g/L. Namely, the content of the C6 fluorine resin in the aqueous solution for impregnation treatment of the C6 fluorine resin is 50g/L to 200 g/L.
The using amount of the blocked isocyanate is 5g/L-20 g/L. That is, the amount of blocked isocyanate added to the aqueous solution for impregnation treatment of C6 fluororesin was 5g/L to 20 g/L.
The usage amount of the water-soluble melamine formaldehyde resin is 10g/L-30 g/L. Namely, the amount of the water-soluble melamine formaldehyde resin added to the aqueous solution for impregnation treatment of C6 fluorine-containing resin is 10g/L to 30 g/L.
The catalyst of the water-soluble melamine formaldehyde resin is an acid catalyst, and the dosage of the catalyst is 1/10-1/2 of the water-soluble melamine formaldehyde resin, wherein the pKa range of the catalyst is any one of phosphoric acid, phosphate, metal salt, organic acid and organic acid salt with 1-3.

The superfine fiber suede artificial leather with the waterproof function is prepared by the manufacturing method of the superfine fiber suede artificial leather with the waterproof function according to any one of the above items.
In the invention, the superfine fiber suede artificial leather semi-finished product is prepared by the following preparation method:
the base cloth is prepared from sea island staple fibers of definite islands or indefinite islands by unpacking, lapping and needling (spunlacing). The base cloth is soaked in polyurethane resin after being heated and shrunk to raise apparent density, and after soaking treatment, the sea part is dissolved (or extracted) by coagulating and alkali liquor (or solvent), and finally the semi-finished product of the superfine fiber suede artificial leather is obtained by sanding, dyeing and finishing.
The invention puts the superfine fiber suede artificial leather semi-finished product into water solution for impregnation treatment of C6 fluorine resin, then dries, and then carries out heat treatment, wherein the temperature of the heat treatment is above 130 ℃, and the treatment time is above 1 minute. Then the finished product of the superfine fiber suede artificial leather with good hydrophobicity, waterproofness and weather resistance can be obtained.
