    • The artificial leather-like sheet is produced by (a) composite spinning a nylon-6 as an island component and a copolymeric polyester as a sea component, (b) opening and carding the composite fiber, laminating it with a web, and needle punching the laminated fiber to make a three dimensional interlaced nonwoven fabric, (c) padding the nonwoven fabric with 5˜10% concn. of a water dispersible polyurethane emulsion, drying it at 100˜120deg. C, and heat-treating it at 150˜170deg. C for 1˜5min, (d) treating the fabric with 5% concn. of a sodium hydroxide solution at 95deg. C for 20˜50min, and (e) dipping the fabric into a dimethyl formamide solution of the polyurethane elastomer. The leather-like sheet has a good softness and bending property.

    • The silver-faced synthetic leather is produced by knitting a tricot of 2-bar structure by using a conjugated micro fiber of 0.1 denier and a polyester yarn of 1.5-3 denier, micronizing the conjugated fiber to obtain a double-raised tricot suede, wet-coating 30-60 wt.% polyurethane resin having at most 30 kg/cm2 of initial elastic modulus on the suede, and coating at least 10 wt.% amino acid resin having 1500-3000 cps (at 30 deg.C) of viscosity and 80-90 kg/cm2 of initial elastic modulus on the polyurethane layer. The synthetic leather looks and feels like a natural leather, may be used in the mfr. of jackets and skirts.
