preparation example Construction

[0015] The high wear-resistant artificial leather of the present invention comprises a polymer elastomer matrix, ultrafine fibers arranged in the polymer elastomer matrix, and formed on the surface of the polymer elastomer matrix and composed of the ultrafine fibers The fluff layer and the massive fusion points formed in the fluff layer; the ultra-fine fiber is the island component of the island-fixed island-in-the-sea composite short fiber, which is polyester or nylon, and its number is 8 islands or more; The block fusion point is formed by the low-melting fiber, which is polyester or copolyester. The diameter of the ultrafine fiber is 0.01 μm to 10 μm; more preferably, the diameter of the ultrafine fiber is 0.1 μm to 6 μm; when the fiber diameter is less than 0.01 μm, the strength of the fiber is weak, and the wear resistance of the artificial leather Consumption is significantly reduced; when the fiber diameter is higher than 10 μm, the hand feeling of the artificial leathe...

Embodiment 1

[0019] This embodiment provides a kind of high wear-resisting artificial leather, and it comprises polymer elastomer matrix (polyurethane), is arranged on the superfine fiber (diameter is about 5 μm) in polymer elastomer matrix, is formed on the surface of polymer elastomer matrix And the fluff layer made of ultra-fine fibers and the massive fusion points formed in the fluff layer; the ultra-fine fibers are the island components of the fixed-island type sea-island composite short fibers, which are polyester or nylon, and the number is between 8 islands and Above; Block melting point is formed by low-melting-point fiber, and it is polyester (PET); The preparation method of this high wear-resisting artificial leather, comprises the following steps:

[0020] (a) Prepare island-fixed island-in-the-sea composite short fibers through two-component spinning equipment: the temperature of the spinning box is 290°C, the spinning speed is 1200m / min, the draw ratio is 3.0, and the single h...

Embodiment 2

[0024] This embodiment provides a high wear-resistant artificial leather, which is basically the same as that in Embodiment 1, except that the number of islands is 16 islands, the low-melting point fiber is a core-sheath composite polyester fiber, and the melting point of the sheath component is 180°C ; Composite short fibers and low melting point fibers are mixed according to the weight ratio of 99.5:0.5, then carded and laid to form a thin layer of reticular fibers, and the fiber layers are entangled by needle punching machine or spunlace machine to form non-woven fabrics; The weight of the cloth is 150g / m 2 .

Abstract

The invention relates to a high-wearability artificial leather and a preparation method thereof. The high-wearability artificial leather comprises a high molecular elastomer matrix, extremely fine fibers which are arranged in the high molecular elastomer matrix, a fluff layer which is formed on the surface of the high molecular elastomer matrix and is prepared from the extremely fine fibers, and blocky melting points which are formed in the fluff layer, wherein the extremely fine fibers are island components of island-fixed type sea-island composite staples and the extremely fine fibers are polyester or nylon and are of 8 islands or above; the blocky melting points are prepared from low-melting-point fibers and are polyester or copolyester. Therefore, the artificial leather is high in leather texture, high in wearability, stable in size, high in color fastness, and outstanding in mechanical property, and is applicable to instep leathers, inner decoration materials of automobiles, furniture leather, and the like.

Description

technical field [0001] The invention relates to an artificial leather, in particular to a highly wear-resistant artificial leather and a preparation method thereof. Background technique [0002] At present, most of the microfiber artificial leathers produced at home and abroad are made of sea-island superfine fibers. After opening and laying processes to make non-woven fabrics, they are subjected to padding polyurethane PU coatings, alkali treatment, sanding, dyeing, Finished and processed. In order to improve the strength, dimensional stability and friction resistance of leather, it is usually achieved by increasing the content of polyurethane PU. However, this will increase the hardness of the leather and reduce the softness, and the application of some high-grade materials will be limited; on the other hand, the manufacturing process of polyurethane is complicated, expensive, and organic solvents will be used in the padding process, which will cause environmental damage....
