Abstract

The invention provides a preparation method of protein leather for earphones. The preparation method comprises the following steps: preparing super soft bass by a wet process, preparing a surface layer by a dry process, coating the surface layer by a bonding layer, drying, dry-mounting on the bass to prepare a semi-finished product, transferring for post treatment, rubbing lines, and drying to obtain a finished product. The method for preparing the protein leather for earphones can well overcome the disadvantages that in use, the traditional leather for earphones has hard texture and easily hurts the skin of users after long-term use; and the protein leather for earphones is more similar to human skin than common leather for earphones, and can meet the requirements of customers for leathers for high-level earphones.

Description

technical field [0001] The invention relates to a preparation method of protein earphone leather, in particular to a preparation method of high-end polyurethane protein earphone leather. Background technique [0002] With the widespread entry of smart phones into people's lives, people use earphones more and more frequently, and earphones have become a standing appliance in people's daily life. Therefore, people have put forward higher requirements for the comfort of earphones, that is, the leather of the skin contacting part of the ear must be a material that is very close to the softness of the skin in the ear. Therefore, the problem of making a kind of earphone leather close to skin texture is placed in front of the earphone leather producer. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of protein earphone leather, which can well solve the problem that the earphone leather material is too hard and easy to sc...
