A COMPOSITE SHEET USED FOR ARTIFICIAL LEATHER WITH LOW ELONGATION AND EXCELLENT SOFTNESS

摘要

The present invention relates to a composite sheet used for artificial leather with low elongation and excellent softness. The composite sheet for artificial leather comprises: a non-woven fabric layer (1) made of ultra fine fibers having a fineness less than 0.3 denier; a woven or knitted fabric layer (2) constructed from a yarn made of ultra fine fibers having a fineness less than 0.3 denier; and polyurethane resin, wherein the ultra fine fibers of the non-woven fabric layer (1) and the ultra fine fibers of the woven or knitted fabric layer (2) are entangled with each other. The composite sheet of the present invention has a stitching strength of more than 30kg/mm, an elongation at constant load of less than 20 % and a stiffness of less than 80mm. Since the composite sheet for artificial leather of the present invention is excellent in both form-stability and softness, it is useful for the production of artificial leather for furniture, cars, men's clothing and sundry goods.
