Abstract
A buffer layer is used to coat on the multi-filament wrapped string to fill the gaps. The polymers of the buffer-layer coating have a high melt-flow (low viscosity) during coating process to fill all the gaps between the filaments, and the filaments are fixed by the coatings onto base core materials. An outer protective coating is applied, which may comprise a composite nylon, clay nanoparticles, carbon nanotubes, an impact modifier, or any combination of the foregoing.
Claims18
A string comprising:
- a core filament of the string wrapped with a plurality of wrapping filaments of a smaller diameter than the core filament;
- a neat nylon buffer layer coating filling in gaps between the wrapping filaments and between the wrapping filaments and the core filament;
- and
- an outer coating covering over the neat nylon buffer layer coating, wrapping filaments and core filament, wherein the outer coating comprises a composite of nylon and two or more different materials selected from the group consisting of clay, carbon nanotubes, and an impact modifier.

A string comprising:
- a core filament of the string having a first diameter, wherein the core filament is wrapped with one or more wrapping filaments having a second diameter that is less than the first diameter;
- a neat nylon buffer layer coating substantially fully filling in gaps between the one or more wrapping filaments and between the one or more wrapping filaments and the core filament;
- and
- an outer coating covering over a circumference of the string so that it covers the one or more wrapping filaments and the nylon in the gaps, wherein the outer coating comprises a composite of nylon and two or more different materials selected from the group consisting of clay, carbon nanotubes, and an impact modifier.
