METHOD FOR FORMATION OF CROSSED STRUCTURE MADE OF TWISTED CONTINUOUS THREAD (VARIANTS), APPARATUS FOR IMPLEMENTATION OF THE METHOD (VERSIONS) AND CROSSED STRUCTURE MADE OF TWISTED CONTINUOUS THREAD MADE BY THIS METHOD

摘要

Improved batts for sleeping bags, insulated apparel, bedding, and other uses are made from a tow of crimped continuous filaments by a machine and process which spreads, extends, and cross-laps the towinto an endless flat-tube structure with desired uniformity, balanced tensile strength, dimensional stability, stretchability, and high loft.
