METHOD FOR DRY HEAT SHRINKING TREATMENT OF LAMINATE AND METHOD FOR PRODUCING ARTIFICIAL LEATHER USING THE SAME METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for a dry heat shrinking treatment without causing breakage or wrinkles and deteriorating a touch feeling in carrying out the dry heat shrinking treatment of a laminate composed of a woven or a knitted fabric and an entangled nonwoven fabric having a dry heat shrinkage percentage different from that of the woven or knitted fabric. SOLUTION: The method for the dry heat shrinking treatment of the laminate is characterized as blowing hot air from the surface side composing a layer having a low dry heat shrinkage percentage when the laminate in which the layer composed of the woven or knitted fabric is entangled and integrated with a layer composed of the entangled nonwoven fabric having a dry heat shrinkage percentage different from that of the woven or knitted fabric is subjected to the dry heat shrinking treatment.
