Problems solved by technology

But they did not pay much attention to durability, resulting in a very short service life of the product
For example, Chinese patent announcement number CN 100560853C provides a kind of high wear-resistant and bright artificial leather, which has wear-resistant, scratch-resistant and resilient properties, and also retains the pearlescent bright effect, so that the surface of the bright leather products made by it has The advantages of three-dimensional effect, impact resistance, good wear resistance and good transparency, but the product does not pay attention to durability and comfort, resulting in a relatively low scope of application and service life of the product
In previous patents, generally if comfort was taken into consideration (for example, microfiber leather is used as the base material), but the durability of the product, that is, the service life of the product, was not paid much attention to, resulting in the overall quality of the product. lower

Embodiment 1

[0039] After melt spinning 50% by weight of polyester chips as the sea component and 50% by weight of nylon chips as the island component, an ultrafine composite fiber with 160 islands and a single fiber fineness of 10 dtex is formed; two stretches are carried out at 180 to 220 degrees, and the stretch The rate is 3.0 times, give it crimp, after cutting, obtain short fibers with a length of 51 mm, card and lay the net to form a fiber web, and then perform needle punching to obtain a double-layer needle-punched non-woven fabric, and immerse the gained non-woven fabric in lye , process at 95 degrees for 30 minutes, dissolve the sea component polyester, fully disperse the nylon in the island part, and form a 0.03dtex superfine fiber non-woven fabric, then fully wash with water to remove the lye and other substances on the surface of the non-woven fabric, and finally grind Hair, dyeing, finishing to form microfiber substrate;

Embodiment 2

[0043] Melt-spinning 50% by weight of polyester chips as the sea component and 50% by weight of nylon chips as the island component to form an ultrafine composite fiber with 370 islands and a single fiber fineness of 15 dtex; stretching twice at 180-220 degrees, stretching The rate is 3.0 times, give it crimp, after cutting, obtain short fibers with a length of 51 mm, card and lay the net to form a fiber web, and then perform needle punching to obtain a double-layer needle-punched non-woven fabric, and immerse the gained non-woven fabric in lye , treated at 95 degrees for 30 minutes to dissolve the sea component polyester, fully disperse the nylon in the island part, and form a 0.002dtex ultra-fine fiber non-woven fabric, then fully wash with water to remove the lye and other substances on the surface of the non-woven fabric, and finally grind Hair, dyeing, finishing to form microfiber substrate;

[0044] Using wet synthetic leather production equipment, the above-mentioned su...

Embodiment 3

[0047] According to the ratio of 50% by weight, nylon and polyester are compounded at the spinneret hole through their respective flow channels to form a specific cross-sectional shape of the fiber, and then ejected from the spinneret hole to become a fiber with a conventional fineness of 3dtex. The fiber is crimped by machinery, cut Finally, short fibers with a length of 51 mm were obtained, which were carded and laid to form a fiber web, and needled to obtain a double-layer needle-punched non-woven fabric. The composite fiber is split to form a 0.3dtex segmented superfine fiber non-woven fabric, then fully washed to remove the lye and other substances on the surface of the non-woven fabric, and finally sanded, dyed, and finished to form a superfine fiber substrate;

[0048] Using wet synthetic leather production equipment, the above-mentioned superfine fiber substrate is impregnated in a solution mainly containing DMF, dimethylformamide, and polyether polyurethane resin, and ...

Abstract

The invention discloses superfine fiber artificial leather which comprises at least three layers, wherein the inner layer is superfine fiber basic material which is a surface formed after polyurethane resin is dipped and provided with microporous, the middle layer is a polyurethane film which contains polyurethane components and fits in with the inner layer, and the surface layer contains an abrasive-resistant polyurethane film. The superfine fiber artificial leather is ageing-resistant. After the superfine fiber artificial leather is used for eight weeks, the wear resistance is above level-4, and the peel intensity is 1.5 kg / cm. After the superfine fiber artificial leather is bent for 100,000 times, the bending resistance is above level-4. Meanwhile, the superfine fiber artificial leather has the advantages of being comfortable, good in crease resistance and wear resistance, and applicable to luggage, clothing, shoes, automotive interior materials or furniture. The superfine fiber artificial leather is high-grade artificial leather which is especially applicable to school bags.

Description

technical field [0001] The invention relates to an artificial leather product, in particular to an application suitable for luggage, clothing, footwear, automotive interior materials or furniture, especially suitable for school bags. Background technique [0002] Artificial leather is now widely used in luggage, clothing, footwear, automotive interior materials or furniture, and some high-end products currently on the market also use artificial leather. [0003] Artificial leather is made of various formulas such as PVC or PU, foamed or coated on a woven or non-woven substrate. In terms of performance, it also emphasizes high strength and high wear resistance. , Emphasizing various types of artificial leather such as color, luster, pattern, etc. on the cloth surface. But they have not paid much attention to durability, resulting in a short service life of the product. For example, Chinese patent announcement number CN 100560853C provides a kind of high wear-resistant and b...
