Abstract
PURPOSE: A bulky composite sheet usable for cushioning and heat insulating materials due to the difference in shrinkages, by bonding plural types of sheets having different shrinkages locally with an adhesive without producing foamable gases.
CONSTITUTION: (C) The adhesive layers 3 of component C are formed intermittently in the width direction between (a) the non-shrinkable or self-stretchable films 1 consisting of component A and (b) the highly-shrinkable films 2, preferably having a shrinkage ≥ 15%, consisting of component B in the order of layers 2,3,1,3,2,1,3, and the layers 2 are shrunk to bulk the resulting sheet. The layers 1 and 2 are made from the polyethylene terephthalate having different shrinkages prepared by different processing steps as the components A and B. An epoxy adhesive is preferably used as the component C.
EFFECT: Bulky fibers are obtained by cutting.
