Embodiment 1

[0010] A preparation process of a black imitation leather fabric, the sea-island fiber 75D / 24F×37 island polyester filament is selected.

[0011] Warp knitting: After warping, use the HKS3 warp knitting machine of Karl Mayer, Germany, with a density of 32 needles / inch and a width of 180 inches to make gray cloth.

[0012] Pretreatment: Add sodium hydroxide, Henkel 88, Henkel 540 at a temperature of 120-130°C for 30-50 minutes;

[0013] Drying: temperature 180~200℃, cloth feeding speed 12m / min;

[0014] Raising: German HR-1 raising machine, 24 needle rollers, card clothing model RA-91, straight needle 3 times;

[0015] Fiber opening treatment: sodium hydroxide 15 g / L, temperature raised to 105°C, time 60 minutes;

[0016] Dyeing: add disperse dyes Black E-ED 12%, Yellow E-RD 0.27%, Red ERD 0.55% at 55°C, auxiliary agent 404 1.5 g / L, leveling agent N140 1.5 g / L, Softener in the bath, raise the temperature to 95°C at 1°C / min, keep warm for 20 minutes, then raise the temperatur...

Embodiment 2

[0021] A kind of preparation technology of beige artificial leather fabric, this preparation technology is different from the formula of the disperse dye that the preparation technology of black artificial leather fabric adopts, and wherein Black E-RD is 12%, RedE-RD is 0.1%, and BlueE-RD is 0.15%, other each process is identical with embodiment 1.

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". Contents of the invention [0003] The pur...
