Problems solved by technology

However, due to the existence of the base fabric layer, the obtained artificial leather has poor flexibility and hard hand feeling, and it is not easy to combine with other materials to make artificial leather composite products, and it is easy to peel off each other, which also limits the application and development of artificial leather in other fields.
The development of non-base cloth artificial leather can effectively solve the above problems and greatly expand the application fields and product performance of artificial leather, but a method for making non-base cloth artificial leather has not yet been disclosed

Embodiment 1

[0019] A method for making artificial leather without base cloth and without foaming, comprising:

[0020] Step 1. Select the base cloth and release paper, and prepare the surface layer slurry and bonding material;

[0021] Step 2. Coat the prepared surface layer slurry on the selected release paper, and form the surface layer after drying;

[0022] Step 3. Dilute the prepared bonding material and apply it on the surface layer, then bond the selected base fabric and dry to form the bonding layer and the base fabric layer;

[0023] Step 4, remove release paper, obtain artificial leather;

[0024] Step 5, peeling off the base cloth layer after the prepared artificial leather is subjected to post-processing, to obtain non-base cloth and non-foaming artificial leather.

[0025] In the above embodiments, the mass concentration of the bonding material can be diluted to 10%-90% of the original and then coated on the surface layer, preferably diluted to 50% of the original.

Embodiment 2

[0027] A method for making foamed artificial leather without a base cloth, comprising:

[0028] Step 1, select base cloth and release paper, prepare surface layer slurry, foaming slurry and bonding material;

[0029] Step 2. Coat the prepared surface layer slurry on the selected release paper, and form the surface layer after drying;

[0030] Step 3, coating the prepared foaming slurry on the surface layer, and forming a foaming layer after foaming;

[0031] Step 4. Dilute the prepared bonding material and apply it on the foam layer, then bond the selected base fabric and dry to form the bonding layer and the base fabric layer;

[0032] Step 5, remove release paper, obtain artificial leather;

[0033] Step 6, after the prepared artificial leather is processed, the base cloth layer is peeled off to obtain the base cloth-free artificial leather.

[0034] In the above embodiments, the mass concentration of the bonding material can be diluted to 10%-90% of the original and then...

Abstract

The invention relates to a production method of base cloth-free artificial leather. The production method comprises the following steps of: when base cloth is adhered, diluting a prepared adhering material for adhering a base cloth layer with other layers, coating the other layers with the adhering material, adhering the selected base cloth, and drying, so as to obtain a bonding layer and the base cloth layer; and carrying out subsequent processing on manufactured artificial leather, and peeling the base cloth layer, so as to obtain the base cloth-free artificial leather. According to the production method, the procedure of compounding the base cloth layer with the other layers is changed based on an existing production process of the artificial leather, so that the technical blank of the base cloth-free artificial leather is filled up; the furthermore, a small amount of bonding layer is remained on the surface of a substrate of the base cloth-free artificial leather after the base cloth layer is peeled, and the surface roughness is greatly improved, so that the base cloth-free artificial leather can be easily compounded with other materials to form artificial leather compound products with a stable structure, and therefore, the application field of the artificial leather is broadened.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to a method for making artificial leather without base cloth. Background technique [0002] Existing artificial leather usually includes a surface layer, a bonding layer and a base cloth layer, and the foamed artificial leather also includes a foaming layer between the surface layer and the bonding layer. The base fabric layer can play a role in shaping the artificial leather during the post-treatment process such as kneading, preventing the artificial leather from being deformed or torn due to external forces. However, due to the existence of the base fabric layer, the obtained artificial leather has poor flexibility and hard hand feeling, and it is not easy to be combined with other materials to form artificial leather composite products, and it is easy to peel off each other, which also limits the application and development of artificial leather in other fields. The ...
