Abstract
Abstract A textile multi-filament yarn having individual filaments cohered together at least in part by individual interfilamentary bridges, which bridges are disposed within the multi-filament yarn to join the filaments thereof so as to render the yarn structurally frozen so that at least a part of the individual filaments cannot be pulled apart without breaking at least in part the structure of the multi-filament yarn. The bridges are made of the same material as the filaments. Some of the segments of individual filaments between consecutive interfilamentary bridges can be of different length.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
92 words
A textile multi-filament yarn comprising individual filaments cohered together at least in part by individual interfilamentary bridges, said interfilamentary bridges being disposed within said multi-filament yarn and joining the filaments thereof so as to render the yarn structurally frozen so that at least a part of the individual filaments cannot be pulled apart without breaking at least in part the structure of the multi-filament yarn, said bridges being made of the same material as said filaments, some of the segments of individual filaments between two consecutive interfilamentary bridges being of different length.
Claim 2
Dependent Claim
92 words
A textile multi-filament yarn comprising individual filaments cohered together at least in part by individual interfilamentary bridges, said interfilamentary bridges being disposed within said multi-filament yarn and joining the filaments thereof so as to render the yarn structurally frozen so that at least a part of the individual filaments cannot be pulled apart without breaking at least in part the structure of the multi-filament yarn, said bridges being made of the same material as said filaments, some of the segments of individual filaments between two consecutive interfilamentary bridges being of different length.
