Abstract
Abstract A breathable lining and shaping material especially suited for garments, comprising a nonwoven layer of randomly arranged fibers superposed on a nonwoven layer of oriented fibers, means holding together the fibers of each layer and holding the layers together, and an outer binder imprinted on the outer face of the oriented fiber layer, the weight of the outer binder being at most 50% of the material weight, the length to width strength ratio of the randomly arranged fiber layer ranging from about 4:1 to 1:4. Advantageously a heat activatable adhesive is provided at spaced locations on the outer face of the randomly arranged layer, whereby the material can be joined to the underside of a garment by hot pressing. The outer binder on the outside of the oriented fiber layer preferably is printed in a regular pattern to ensure that all fibers are tied down by bonds at multiple points.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A breathable lining and shaping material especially suited for garments, comprising a nonwoven layer of randomly arranged fibers superposed on a nonwoven layer of oriented fibers, means holding together the fibers of each layer and holding the layers together, and an outer binder imprinted on the outer face of the oriented fiber layer for the purpose of bonding the oriented fibers of the non-woven layer together, the weight of the outer binder being at most 50% of the material weight, the length to width strength ratio of the randomly arranged fiber layer ranging from about 4:1 to 1:4.
Claim 2
Dependent Claim
