Title:
BULKY NONWOVEN FABRIC
Document Type and Number:
Japanese Patent JP3138145
Kind Code:
B2
Abstract:
PURPOSE: To obtain bulky nonwoven fabric having apparent thickness increased in ≥ twice the thickness before shrinkage treatment and a great number of wrinkles like massed fine piles made into a short rib state.
CONSTITUTION: A second fiber layer composed of not substantially thermally shrinkable yarn is piled on at least one side of a first fiber layer comprising at least 50wt.% of highly shrinkable yarn having the maximum shrinkage percentage (S%) by heating of at least 50%. These two layers are interlaced between yarns to give interlaced nonwoven fabric. The interlaced nonwoven fabric is heat-treated and the first fiber layer is shrunk to increase the thickness of the second fiber layer. Consequently, bulky nonwoven fabric having formed a great number of wrinkles on the surface of the second fiber layer and apparent thickness of ≥ twice the thickness of the interlaced nonwoven fabric is obtained.
