ABSTRACT:
A method of making a flexible fabric composed of a fibrous matrix of ribbon-like, conjugate, spun filaments. The method includes the following steps: 1) providing a fibrous matrix composed of individual, spun filaments bonded at spaced-apart bond locations, the filaments themselves being composed of: (i) a core formed of at least one low-softening point thermoplastic component; and (ii) a sheath formed of at least one high-softening point component; and 2) applying a flattening force to the fibrous matrix to durably distort the core of individual filaments into a ribbon-like configuration having a width greater than its height so that: (i) the individual filaments are substantially unattached between the spaced-apart bond locations, and (ii) the width of individual filaments is oriented substantially in the planar dimension of the fabric. Also disclosed is a flexible fabric composed of a fibrous matrix of ribbon-like, conjugate, spun filaments joined at spaced apart bond locations.
