Problems solved by technology

[0003] However, due to the high price of real leather and the low elasticity of general leather, it is difficult to manufacture tight-fitting garments that can reflect the curves of the human body with general leather. After wearing for a period of time, wrinkles are prone to appear on the surface of the leather, which affects the appearance

Embodiment 1

[0020] In the embodiment of the present invention, a kind of artificial leather processing method comprises the following steps:

[0021] (1) skin pretreatment:

[0022] The first layer of cowhide is selected, dehaired, degreased, degreased and neutralized, and the pH value is kept at about 5.8, dried in the air, and then cut to a thickness of 0.3mm by a leather cutter to obtain semi-finished leather pieces.

[0023] (2) Cloth pre-stretching:

[0024] The pre-prepared elastic cloth is cut into the shape of the semi-finished skin, and the size ensures that it is consistent with the size of the semi-finished skin when it is kept in a pre-stretched state, and the stretch rate of the elastic cloth is 5%.

[0025] (3) Cloth glue:

[0026] Bond one side of the non-woven fabric and the elastic fabric together through natural latex, and trim the non-woven fabric to the shape and size of the elastic fabric.

[0027] (4) High temperature and high pressure bonding:

Embodiment 2

[0036] In the embodiment of the present invention, a kind of artificial leather processing method comprises the following steps:

[0037] (1) skin pretreatment:

[0038] The first layer of sheepskin is selected, dehaired, degreased, degreased and neutralized, and the pH value is kept at about 5.5. After drying, the skin is cut to a thickness of 0.5mm with a skin slicer to obtain semi-finished skin slices.

[0039] (2) Cloth pre-stretching:

[0040] The pre-prepared elastic cloth is cut into the shape of the semi-finished skin, and the size ensures that it is consistent with the size of the semi-finished skin when it is kept in a pre-stretched state, and the stretch rate of the elastic cloth is 20%.

[0041] (3) Cloth glue:

[0042] Bond one side of the non-woven fabric and the elastic fabric together through natural latex, and trim the non-woven fabric to the shape and size of the elastic fabric.

Embodiment 3

[0052] In the embodiment of the present invention, a kind of artificial leather processing method comprises the following steps:

[0053] (1) skin pretreatment:

[0054] The first layer of sheepskin is selected, dehaired, degreased, degreased and neutralized, and the pH value is kept at about 5.6. After drying, the skin is cut to a thickness of 0.4mm with a skin slicer to obtain semi-finished skin slices.

[0055] (2) Cloth pre-stretching:

[0056] The pre-prepared elastic cloth is cut into the shape of the semi-finished skin, and the size ensures that it is consistent with the size of the semi-finished skin when it is kept in a pre-stretched state, and the stretch rate of the elastic cloth is 10%.

[0057] (3) Cloth glue:

[0058] Bond one side of the non-woven fabric and the elastic fabric together through natural latex, and trim the non-woven fabric to the shape and size of the elastic fabric.

Abstract

The invention discloses a processing method of artificial leather. The method comprises the following steps: (1) subjecting animal skin to fur removing, deoiling and degreasing neutralizing treatment, airing and cutting the animal skin to obtain a semi-finished leather piece; (2) cutting elastic fabric into the shape of the semi-finished leather piece, wherein the size of the elastic fabric is set to ensure that the size of the elastic fabric at the pre-stretching state is kept consistent with the size of the semi-finished leather piece; (3) adhering non-woven fabric with one side of the elastic fabric together, trimming the non-woven fabric until the shape and the size of the non-woven fabric are same with the shape and the size of the elastic fabric; (4) uniformly applying adhesive on the meat surface of the semi-finished leather piece, aligning the surface of the semi-finished leather piece with the other side of the elastic fabric, bonding them; spreading and airing them, and releasing the pre-stretching state of the elastic fabric to obtain the leather semi-finished product; (5) performing printing and dyeing by printing and dyeing paper and removing the printing and dyeing paper; (6) processing the leather by using a leather processing treatment agent to obtain a leather finished product. The leather material produced by the method is soft in surface and good in elasticity, the leather is not easy to deform and has the same color, luster and service life with the real leather.

Description

technical field [0001] The invention relates to the technical field of leather processing, in particular to a method for processing imitation leather. Background technique [0002] Natural leather is obtained by processing smooth and suede panels of animals (generally, tanned animal fur is called fur). Because natural leather has excellent natural characteristics such as softness, breathability, elasticity, and comfortable wearing, it is widely used in daily necessities and industrial products. Leather products have become an indispensable part in people's daily life, such as leather clothes, shoes and other clothing, leather chairs, sofas and other household items. When people use leather, they need highly elastic leather products in order to pursue beauty and comfort. For example, many fashionable women like to wear leather tight miniskirts, leggings, and high elastic boots. [0003] However, due to the high price of real leather and the low elasticity of general leather...
