Abstract
Official abstract text for this publication.
Disclosed herein are filamentary braids containing a plurality of filamentary elements braided together, where the filamentary elements include one or more main filamentary elements and one or more looped filamentary elements. The looped filamentary elements are arranged in one or more looped structures extending outward from the longitudinal axis formed by the main filamentary elements. The looped filamentary elements are made of a fiber having a tensile modulus of 2.3 GPa or more. Upon application of selective tension to the looped filamentary elements, the looped filamentary elements (i) are collapsible against the main filamentary elements in the filamentary braid and/or (ii) are removable from the filamentary braid.
First claim
Opening claim text (preview).
What is claimed is: 1. A filamentary braid comprising a plurality of filamentary elements braided together, wherein the filamentary elements comprise one or more main filamentary elements and one or more looped filamentary elements, wherein the looped filamentary elements are arranged in one or more looped structures extending outward from the longitudinal axis formed by the main filamentary elements, wherein the looped filamentary elements are made of a fiber having a tensile modulus of 2.3 GPa or more, and wherein, upon application of selective tension to the looped filamentary elements, the looped filamentary elements (i) are collapsible against the main filamentary elements in the filamentary braid and/or (ii) are removable from the filamentary braid. 2. The filamentary braid of claim 1 , wherein the looped filamentary elements are a different color than the main filamentary elements. 3. The filamentary braid of claim 1 , wherein the looped filamentary elements comprise one or more liquid crystal polymer filaments. 4. The filamentary braid of claim 3 , wherein the looped filamentary elements consist of one or more liquid crystal polymer filaments. 5. The filamentary braid of claim 1 , wherein the main filamentary elements comprise one or more liquid crystal polymer filaments. 6. The filamentary braid of claim 5 , wherein the main filamentary elements consist of one or more liquid crystal polymer filaments. 7. The filamentary braid of claim 1 , wherein the main filamentary elements and the looped filamentary elements differ in surface friction. 8. The filamentary braid of claim 7 , wherein the main filamentary elements, the looped filamentary elements, or both, comprise a low-friction coating. 9. The filamentary braid of claim 1 , wherein the looped filamentary elements are collapsible against the main filamentary elements in the filamentary braid upon application of selective tension to the looped filamentary elements. 10. The filamentary braid of claim 1 , wherein the looped filamentary elements are removable from the filamentary braid upon application of selective tension to the looped filamentary elements. 11. The filamentary braid of claim 1 , wherein the looped filamentary elements are monofilament fibers. 12. The filamentary braid of claim 1 , wherein the main filamentary elements are monofilament fibers. 13. A method of producing the filamentary braid of claim 1 , comprising braiding together filamentary elements fed from a plurality of bobbins, wherein at least one bobbin operates at a lower tension and/or faster feed rate than other of the bobbins, wherein the looped filamentary elements are formed from said at least one bobbin operating at a lower tension and/or faster feed rate, and wherein the main filamentary elements are formed from said other bobbins. 14. The method of claim 13 , wherein said at least one bobbin operates at a lower tension than said other bobbins. 15. The method of claim 13 , wherein said at least one bobbin operates at a faster feed rate than said other bobbins.
