Abstract (en)

[origin: EP0165345A1] This invention presents an artificial leather and a dyeing method of ultrafine polyamide fibers, particularly a grained artificial leather, having bright, deep colour, good colour fastness to dry cleaning with charged soap, delicate touch free from undesirable rubber-like feeling as well as high durabilites. The object of this invention is attained partly by using a super-entangled fiber base comprising ultrafine polyamide fibers and/or bundles thereof, and applying thereon a polyurethane including polyoxyethylene of molecular weights of 500 - 5,000 as a soft segment. The object of this invention is also partly attained by dyeing the polyamide ultrafine fibers with a metal-dye complex and a fixing agent treatment. This invention is most suitable for manufacturing grain artificial leathers especially for clothing. Other uses are such as for shoes, belts, bags, gloves and balls.
