Embodiment 1

[0034] A kind of manufacture method of microfiber leather for automobile, it comprises the steps:

[0035] (1) The ironed microfiber non-woven fabric with a weight of 400g / ㎡ and a thickness of 1.45 is impregnated with polyurethane slurry at a speed of 4m / min, then foamed through a coagulation tank, and then washed with water in a washing tank. Polyurethane slurry ratio table 3:

[0036] table 3

[0037] serial number raw material name weight / kg 1 Polyurethane resin 100 2 DMF 33 3 dye solution 1.2 4 Cell regulator JS-MS 0.6 5 Antifouling additive VS-128 0.3

[0038] (2) Pass the base fabric treated in step ① through the toluene extraction tank and the hot water recovery 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 tenter-dried in an oven with a temperature of 130°C, and the speed depends on the length of the oven.

[0040] (4) Pass...

Embodiment 2

[0046] A kind of manufacture method of microfiber leather for automobile as described in embodiment 1,

[0047] The grammage and thickness of the microfiber non-woven fabric described in step (1) were prepared using the following two sets of data:

[0048] Gram 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 gram weight and thickness of the microfiber non-woven fabric are between 400 g / ㎡-520 g / ㎡ and 1.45-1.95 mm, and the made automobile microfiber leather can all achieve the purpose of the present invention.

Embodiment 3

[0052] A kind of manufacture method of microfiber leather for automobile as described in embodiment 1,

[0053] In step (1), the speed of the superfiber nonwoven fabric is controlled at 5, 6, 7, 8, 9, and 10 m / min, respectively.

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

[0055] Example 3:

[0056] A kind of manufacture method of microfiber leather for automobile as described in embodiment 1,

[0057] The base cloth described in step (2) is prepared by controlling the speeds of the toluene extraction tank and the water washing tank at 5, 6, 7, 8, 9, and 10 m / min, respectively.

[0058]The test shows that when the speed of the base cloth passing through the toluene extraction tank and the water washing tank is controlled at 4-10m / min, the automobile microfiber leather made can all ac...

Abstract

The invention provides a novel preparation method of microfiber leather being used for automobile seats in our nation and having antifouling and antibacterial performances. According to the method, one or more antifouling aids are added into wet-method impregnation polyurethane slurry; one or more antibacterial and antifouling aids are added into an oiling softening liquid; after thermosetting, nonwoven fabric is sequentially processed through the steps of wet-method impregnation, toluene reduction, widening and oiling, and tanning, such that a prepared unfixed-island microfiber base fabric has special antifouling and antibacterial functions; after dry-method coating, the surface of the coating is subjected to antifouling printing, such that the prepared microfiber leather has special comprehensive antifouling and antibacterial performances. The microfiber leather is used in automobile interiors such as automobile seats, armrests, door panels, and the like. The material has good surface texture and antifouling and antibacterial performances.

Description

technical field [0001] The invention relates to a preparation method of antifouling and antibacterial automobile superfiber leather, in particular to a preparation method of superfiber leather for automobile seats and interior decorations. Background technique [0002] Microfiber leather, the full name is "microfiber polyurethane synthetic leather". Microfiber leather is a new type of high-grade leather in synthetic leather. It is named for its very fine fiber filaments. It is 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 the comfort, cleanliness, no peculiar smell, and environmental protection of car seats and interiors. Although leather seats are luxurious and comfortable, they are expensive on the one hand, and secondly, the production process causes serious environmental pollution; other artificial leathers such as PVC have d...
