Problems solved by technology

[0002] At present, most of the artificial leather sold in the market is obtained by impregnating polyurethane resin on non-woven fabrics made of ordinary non-hollow fibers. However, such products have shortcomings in terms of hand feel and appearance. Microfiber as a fiber raw material for non-woven fabrics has become a trend
As disclosed in the patent document CN101454503A, a substrate for artificial leather and grained artificial leather, the substrate contains an entangled nonwoven fabric formed by superfine fibers and an adhesive resin, and at least one side is not attached to the adhesive resin. A dense layer formed of microfibers, the part other than the dense layer is impregnated with binder resin, the nonwoven fabric here contains fibers that produce microfibers with water-soluble thermoplastic polyvinyl alcohol resin as the removed component, and the obtained artificial leather It has high peel strength, softness without rebound feeling, body-like feel, and dense creases, but such products still have the problem of insufficient light weight
[0003] In addition, there are also research reports on the sea-island type superfine polyester fiber as the fiber raw material of non-woven fabrics. As disclosed in the patent document CN101629387A, a kind of superfine fiber knitted cloth synthetic leather and its manufacturing method are disclosed. The sea-island type superfine polyester fiber is formed Knitted fabrics replace microfiber non-woven fabrics to solve the problems of uneven dyeing, poor color fastness, and poor hand feeling when non-woven fabrics are used as substrates. Fits perfectly, and the lightweight problem still hasn't been solved

Embodiment 1

[0024] A 150-denier island-in-the-sea composite fiber with styrene as the sea component and hollow polyester as the island component is selected as the raw material. The hollow polyester with the island component has a circular section and a hollow rate of 40%. The composite fiber is stretched and cut to obtain short fibers , and then the short fibers are carded, laid, and needled to form a double-layer needle-punched non-woven fabric, and then the resulting non-woven fabric is immersed in lye, and treated at 100 degrees for 35 minutes to dissolve the sea part and fully disperse the island part , to obtain a superfine fiber non-woven fabric with a monofilament fineness of 0.005dtex, then fully wash to remove the lye and other substances on the surface of the non-woven fabric; then sand, dye, and arrange the above-mentioned non-woven fabric to form a substrate.

[0025] Next, wet synthetic leather production equipment is used to immerse the above-mentioned substrate in a polyure...

Embodiment 2

[0029] The non-sea-island type hollow polyester fiber is selected as the raw material, and the rest is the same as in Example 1 to obtain the artificial leather of the present invention.

[0030] The grammage of gained leather is 420g / m 2 , the thickness is 0.7mm, and the bursting strength is 680kpa. The parameters are shown in Table 1.

Embodiment 3

[0032] The hollow polyester of the island component in the sea-island type composite fiber used has a hollow rate of 67%, and the rest is the same as in Example 1 to obtain a finished product.

[0033] The grammage of gained leather is 280g / m 2 , the thickness is 0.6mm, and the bursting strength is 630kpa. The parameters are shown in Table 1.

Abstract

The invention discloses a low-weight artificial leather and application thereof. The artificial leather is composed of a base cloth layer and a leather layer, the base cloth layer is a non-woven fabric soaked in polyurethane resin, and the non-woven fabric is made by hollow polyster fibers. According to the low-weight artificial leather, the non-woven fabric formed by the hollow polyster fibers isused as a base material, the low weight of the product is achieved, various physical indexes are guaranteed, and the leather is lower in weight. In this way, through schoolbags, backpacks and the like made through the leather product, the burden of a traveler can be reduced, so that travelling is easier.
