Document Type and Number:
WIPO Patent Application WO/1991/019032
Kind Code:
A1
Abstract:
A cushioning structure improved in impact resilience, compression endurance and compression recovery and free from the impression of bottoming, comprising a matrix and elastic composite fibers made from thermoplastic elastomer dispersed therein, wherein amoeboid, omnidirectionally flexible thermal fusion points formed at the intersections of the composite fibers with each other and quasi-omnidirectionally flexible thermal fusion points formed at the intersections of the composite fibers with nonelastic short polyester fibers are scattered and part of the fibers in the composite fibers present between adjacent thermal fusion points have at least one spindle-shaped knot in the longitudinal direction thereof.
