Abstract
Disclosed are methods for forming flexible, kink-resistant shaped fabric products which are particularly well adapted for protecting and/or covering elongate substrates, such as cables, conduits, wiring and the like. The shaped fabric products include a wall portion formed from a filamentary material which is resiliently set in a spiral configuration with respect to the longitudinal axis of the shaped product. The wall portion may also preferably formed with a filamentary material in the form of circumferential hoops substantially conforming in shape and size to the cross-sectional configuration of the shaped product.
Claims5
A method of making a flexible, abrasion- and kink-resistant sleeve product having a substantially circular cross-section with respect to a central longitudinal axis, said sleeve providing protection for elongated articles such as wires, cables, hoses and conduits, said sleeve having an ARP abrasion resistance of at least 25,000 cycles, the method comprising:
- providing warp and fill ends of resilient monofilaments, at least said warp monofilaments being of a resiliently settable material;
- forming a sleeve product by relatively loosely interlacing said selected warp and fill monofilament ends to provide an open construction having uniformly dispersed openings;
- and
- resiliently setting at least one of said resilient monofilament warp ends in a spiral configuration extending at an acute angle with respect to said central longitudinal axis.
