Problems solved by technology

[0002] The disadvantage of the existing technology is that the base fabric is four-way elastic, so it increases the difficulty in the production process. We can only combine the base fabric with a layer of interlining and then produce wet-laid bass, which increases the cost and production difficulty.

preparation example Construction

[0037] A method for preparing leather for earphone covers, which is characterized in that it includes polyurethane wet-process resin, dimethylformamide, wood powder, cell regulator, color paste, four-way elastic ultra-soft and ultra-thin base cloth, and release paper , Polyurethane surface layer resin, polyurethane adhesive layer resin, butanone, additives, environmentally friendly halogen-free pigments;

[0038] Including the following steps:

[0039] (1) Wet mixing ingredients:

[0040] a. Stir 5kg of dimethylformamide and 2kg of color paste at high speed for 60 minutes, filter for later use, and record it as material a;

[0041] b. Stir 40kg of dimethylformamide and 30kg of wood powder for 30 minutes, let it stand for 20 minutes and then mix it with material a evenly for later use, which is recorded as material b;

[0042] c. Add 100kg of polyurethane wet-process resin to material b and stir for 20 minutes, then defoam and filter and seal for use, which is recorded as mat...

Embodiment 2

[0054]Embodiment 2, a kind of earphone cover is used leather, it is characterized in that, comprises veneer layer, adhesive layer, foam layer and base cloth, the lower layer of veneer layer is connected with adhesive layer upper layer, and adhesive layer lower layer and foam layer upper layer Connection, the lower layer of the foam layer is connected with the upper layer of the base fabric.

[0055] In this embodiment, the dry-process veneer layer includes polyurethane surface layer resin, dimethylformamide, methyl ethyl ketone, additives and halogen-free toner, and its mass components are: polyurethane surface layer resin 90 parts, 30 parts of dimethylformamide, 50 parts of butanone, 0.8 parts of additives, and 5 parts of halogen-free toner. The structure of the improved dry-process veneer layer mainly improves the dry-process fabric resin with extremely low modulus compared with the conventional dry process, and has the characteristics of skin feeling.

[0056] In this embo...

Abstract

The invention discloses earphone sleeve leather and a preparation method thereof. The earphone sleeve leather comprises a facing layer, an adhesive layer, a foaming layer and a backing fabric, a lowerlayer of the facing layer is connected with an upper layer of the adhesive layer, a lower layer of the adhesive layer is connected with an upper layer of the foaming layer, and a lower layer of the foaming layer is connected with an upper layer of the backing fabric. The earphone sleeve leather has the advantages that compared with the prior art, the headphone sleeve leather has the characteristics of four-direction elasticity, super softness and skin feeling, and an earphone sleeve made of the leather is very comfortable and can provide baby-like skin feeling.

Description

technical field [0001] The invention relates to leather for earphone covers and a preparation method thereof, belonging to the technical field of leather manufacturing. Background technique [0002] The disadvantage of the prior art is that the base fabric is four-way elastic, so it is more difficult in the production process. We can only combine the base fabric with a layer of interlining and then produce wet-laid bass, which increases the cost and production difficulty. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a leather for earphone cover and its preparation method, which has the characteristics of four-way elasticity, super softness and skin feeling. [0004] In order to solve the above-mentioned technical problems, the present invention provides a kind of leather for earphone cover, it is characterized in that, comprises veneer layer, adhesive layer, foam laye...
