The invention discloses thin type micro villus
polyurethane certificate leather and a preparation method of the thin type micro villus
polyurethane certificate leather. The preparation method of the thin type micro villus
polyurethane certificate leather takes a 0.45 imitated micro
fiber fabric base raising on a single face as a carrier and comprises the following steps: directly
coating a polyurethane resin layer with a certain
viscosity on the raised surface of the 0.45 imitated micro
fiber fabric base, after coagulation, forming a polyurethane
epithelium on the surface of the fabric base after cohesion, and during the film formation process, sequentially carrying out washing for displacing a DMF (
dimethyl formamide)
solvent,
drying and shaping the polyurethane
epithelium, so as to obtain a semi-finished product; carrying out oriented buffing and tentering on the
surface layer of the semi-finished product, then carrying out aftertreatment and colour alternation, so that the thin type micro villus polyurethane certificate leather finished product is obtained. The thin type micro villus polyurethane certificate leather obtained by adopting the preparation method has the advantages of fine villus, soft handfeel, light weight, superior air permeability and downy feeling like micro
fiber, a certificate leather lining made adopting the thin type micro villus polyurethane certificate leather shines with dazzling brilliance, is decent and has excellent protective properties, such as shakeproof, breakageproof and scratchproof properties, on a delicate article, and the thin type micro villus polyurethane certificate leather is especially applicable to linings of shells of a
mobile phone, a computer and the like.
