Abstract

A hollow monofilament of a high temperature spinnable thermoplastic such as Polyetheretherketone (PEEK) which is substantially hollow by up to about 80% by volume and has an outer diameter in the range from about 0.07 to 0.80 mm. is used in the construction of braiding in substitution for solid monofilaments with the advantage of lower cost and increased abrasion resistance.

Claims

1. A lightweight abrasion resistant braid comprising monofilaments of spinnable thermoplastics in which each monofilament is substantially hollow by up to 80% by volume and with outer diameters in the range from about 0.07 to 0.80 mm.

2. A braid according to claim 1 wherein each monofilament is substantially hollow by about between 10-80% by volume.

3. A braid according to claim 1 in which part or all of the monofilaments are made of polyaryletherketones.

4. A braid according to claim 1 in which part or all of the monofilaments are made of PEEK.

5. A monofilament for making a braid according to claim 1.

6. A monofilament for making a braid according to claim 2.
