Procedure for the production of a laminar structure resistant to progressive tearing, a laminar structure resistant to progressive tearing and its use

摘要

Procedure for the production of a laminar structure resistant to progressive tearing, in which a starting laminar structure is used based on spun yarns, fibers or filaments, which are formed on the basis of at least two elementary filaments and which, considered / as in cross section, they have an arrangement of orange segments or respectively pieces of pie with segments based on different polymers, and the starting sheet structure is subjected to a compressive heat treatment, the polymer segments being crossed and reaching a essentially non-sticky bonding by riveting or welding of the polymer segments, using pairs of polymers, chosen from those formed by a polypropylene and a polyethylene, by a polyamide 6 and a polyethylene, by a poly (ethylene terephthalate) and a polyethylene, by a polyamide 6 and a polypropylene or by a poly (ethylene terephthalate) and a polypropylene ileum
