Preparation process of artificial leather shell material

Abstract

A rpeparation process of imitation real leather shell fabric with excellent elasticity, air permeability, heat insulating ability, crease-resistance and buckskin effect includes the procedures of warp knitting, grey fabric, pretreatment, drying, raising, opening, dyeing, carding, shearing, grinding and foring, and is characterized by that its raw material is of "islands-in-sea" type fibre, and the technological condition of pretreatment is as follows: adding adjuvant at 120-130 deg.C, treatment time is 30-50 min., the technological condition of raising process is as follows: number of pin-rollers of raising machine is 24, model of card clothing is RA-91, and frame needling for three times; and the condition of opening treatment is that adding sodium hydroxide 10-15 g / l at 100-150 deg.C, heating time is 60-90 min., and the condition of grinding process is that grinding roller speed is 1200 rpm, pressing distance is 3mm and abrasive paper specification is 140-180 meshes.

Description

technical field [0001] The invention relates to a textile fabric, in particular to a preparation process of a simulated leather fabric. Background technique [0002] Faux leather fabric, which is traditionally called suede fabric, has been on the market for many years. Most of them are needle-punched into non-woven fabrics and woven fabrics. It is compounded by coating a layer of plastic on it. In addition, some manufacturers use release paper as a carrier, apply PVC mixture on the release paper, heat at an appropriate temperature, gel cooling, foaming, lamination and plasticization processing, as well as wet processing to manufacture suede. The above products are also widely used, but due to the selection of raw materials, weaving methods, and finishing processes, the resulting garment fabrics have poor air permeability, softness, and elasticity. , warmth retention, wrinkle resistance are poor, and there is no "writing effect".
