Example Embodiment

[0014] Example 1

[0015] A reposting crystal mirror leather, which is made by a dry film transfer processing method, using superfine fiber non-woven fabric as the base fabric, the fineness of the base fabric is 0.003dex, and the base fabric is coated with an aqueous polyurethane resin slurry. The water-based polyurethane resin slurry is divided into two layers, namely the surface layer and the bottom bonding layer, then the leather base cloth is bonded, the paper and leather are separated, the crystal is bonded, and finally the leather slurry is bonded.

[0016] The surface layer is made of the following raw materials in parts by weight: 100 parts of water-based polyurethane resin; 60 parts of dimethylformamide; 40 parts of surfactants; 13 parts of pigments; 2 parts of thickeners and 0.5 parts of defoamers; 0.2 parts of leveling agent; 0.05 parts of wetting agent.

[0017] The bottom bonding layer is made of the following raw materials in weight fraction: 100 parts of water-based p...

Abstract

The invention relates to mirror-surface leather with crystal transferred and attached. The mirror-surface leather is manufactured with a dry-process film-transferring machining method. Ultra-fine fiber non-woven fabric is selected to serve as backing fabric, the backing fabric is coated with water-borne polyurethane resin slurry which is divided into two layers of a surface layer and a backing layer adhesion layer respectively, then leather base cloth is attached, paper and leather are separated, the crystal is attached, and finally leather slurry is attached; the temperature of an oven is controlled to range from 120 DEG C to 130 DEG C during first coating, a doubling roller for transfer and attachment of the crystal is controlled to be at a normal temperature, and the flow of water is synchronous with the rotation speed of the doubling roller. The produced crystal mirror-surface leather does not have air bubbles or needle holes, is high in transmittance and good in brightness, has a flat and smooth surface and can be suitable for multiple fields such as sofa, automotive trims, office accommodations, furniture and walls.

Description

Technical field [0001] The invention relates to the leather field, in particular to a crystal mirror leather for transferring. Background technique [0002] In the field of leather technology, there are natural leather and artificial synthetic leather. The common name for leather in the leather product market is a customary name for people to distinguish between synthetic leather and natural leather; in consumers’ minds, leather is also It has a non-fake meaning. In fact, real leather is leather. It is mainly processed from mammalian animal skins. Therefore, the real leather or synthetic leather on the market is actually artificially made. [0003] At present, after years of development, polyurethane synthetic leather is widely used in home furnishings, sofas, car interiors, luggage, etc. due to its good appearance, feel, breathability and moisture permeability, solvent resistance, convenient application, and many varieties of colors. , Office supplies, etc. [0004] The existing m...
