TUBE-SHAPED WOVEN FABRIC TO PREVENT THE AGROUNDATION OF VELVET FEATHERS

Abstract

The invention proposes a pouch-like fabric, comprising at least one tubular pouch, in which each tubular pouch consists of: a tubular side wall formed between the two ends of the tubular pouch; at least two filling chambers formed between the two ends and enclosed by the tubular side wall; and at least one mesh barrier provided between the two filling chambers and essentially perpendicular to the tubular side wall, in which the filling chambers are interconnected. The mesh barrier allows the filling material to be retained in the filling chamber and prevents it from migrating to adjacent filling chambers, so that the filling material cannot accumulate in one place due to gravity or other external forces. Thus, the pouch-like fabric of the invention can maintain the desired thermal insulation properties after a period of use with the filling material evenly distributed inside.
