[0038] (2) Pass the base fabric treated in step ① through the toluene extraction tank and the hot water extraction tank at a speed of 4m / min. This is a conventional microfiber toluene reduction process.

[0039] (3) The base fabric treated in step ② is subjected to tentering drying and shaping in an oven at a temperature of 130°C, and the speed depends on the length of the oven.

[0040] (4) Pass the base fab...

Embodiment 2

[0046] A manufacturing method of microfiber leather for automobiles as described in Example 1,

[0047] In step (1), the grammage and thickness of the microfiber nonwoven fabric are prepared using the following two sets of data:

[0048] Weight: 410, 420, 430, 460, 470, 480, 490, 500, 510, 520;

[0049] Thickness: 1.5, 1.55, 1.6, 1.65, 1.7, 1.75, 1.8, 1.85, 1.9, 1.95.

[0050] Tests show that the grammage and thickness of the microfiber non-woven fabric are between 400 g / ㎡-520 g / ㎡ and 1.45-1.95 mm, and the manufactured automobile microfiber leather can achieve the purpose of the present invention.

Embodiment 3

[0052] A manufacturing method of microfiber leather for automobiles as described in Example 1,

[0053] In step (1), the speed of the microfiber non-woven fabric is controlled at 5, 6, 7, 8, 9, and 10 m / min for preparation.

[0054] Tests show that when the speed of the superfiber non-woven fabric impregnated by the polyurethane slurry is controlled at 4-10m / min, all the made automobile superfiber leather can achieve the purpose of the present invention.

[0055] Example 3:

[0056] A manufacturing method of microfiber leather for automobiles as described in Example 1,

[0057] The base fabric described in step (2) is prepared when the speed of the toluene extraction tank and the water washing tank are controlled at 5, 6, 7, 8, 9, 10 m / min, respectively.

[0058] Tests have shown that when the speed of the base fabric passing through the toluene extraction tank and the washing tank is controlled at 4-10 m / min, all the made automobile microfiber leathers can achieve the purpose of the pre...

Abstract

The present invention is mainly aimed at a new manufacturing method of microfiber leather with antifouling and antibacterial properties for domestic car seats. The main method is to add one or more antifouling additives to the wet impregnated polyurethane slurry , add one or more antibacterial additives and antifouling additives to the oiling and softening liquid, when the heat-set non-woven fabric is sequentially wet impregnated, toluene decremented, oiled by spreading, and kneaded. The prepared island of adventitious microfiber base cloth has special antifouling and antibacterial properties. Then after dry coating, antifouling printing is carried out on the surface of the coating, and the prepared microfiber leather has special all-round antifouling and antibacterial properties. Among them, it has good surface touch and antifouling and antibacterial properties.

Description

Technical field [0001] The invention relates to a preparation method of anti-fouling and antibacterial automobile microfiber leather, in particular to a preparation method of microfiber leather for automobile seats and interior decoration. Background technique [0002] Microfiber leather, the full name is "microfiber polyurethane synthetic leather". Microfiber leather belongs to a new type of high-grade leather in synthetic leather. It is named because of the very fine fiber filaments of its structure. It belongs to a newly developed high-grade leather in synthetic leather. At present, with the rapid development of China's automobile industry, drivers and passengers have higher and higher requirements for comfort, cleanliness, no odor, and environmental protection of car seats and interiors. Although leather seats are luxurious and comfortable, on the one hand, the price is high, and the production process causes serious environmental pollution; PVC and other artificial leather ...
