Abstract
Various implementations of yarns and multi-component filaments having a plurality of solid particles dispersed throughout a portion of the filaments are described herein. Inclusion of solid particles through a portion of the filaments allows for differing certain properties in products formed from the filaments while maintaining desirable physical properties such as strength or abrasion resistance. For example, including translucent or transparent particles, such as glass flakes or mica, may differ the visual properties, such as providing an increased luster. And, in other implementations, opaque solid particles may be included through a portion of the filaments to create a different property for a product formed with the filament.

A multi-component filament comprising:
- a first component comprising a first polymer;
- and
- a second component comprising a second polymer and a plurality of transparent or translucent solid particles evenly dispersed within the second polymer;
- wherein the second component defines at least 50 percent of an external surface area of the multi-component filament.
A yarn comprising at least one of a first filament and at least one of a second filament;
- wherein the first filament comprises a first polymer;
- and
- wherein the second filament comprises a second polymer and a plurality of solid particles evenly dispersed within the second polymer.
A multi-component filament comprising:
- a first component comprising a first polymer with a plurality of solid particles evenly dispersed within the first polymer;
- and
- a second component comprising a second polymer and a plurality of solid particles evenly dispersed within the second polymer;
- wherein the second component defines at least 50 percent of an external surface area of the multi-component filament;
- wherein the first and second polymers are each selected from the group consisting of a polyamide, a polyester, and a polyolefin;
- wherein the solid particles comprise glass flakes with an average particle diameter ranging from 5 microns to 35 microns and an average thickness ranging from 0.5 microns to 8 microns, and have been treated with a silane coupling reagent selected from the group consisting of 3-aminopropyltriethoxysilane, vinyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, and 3-methacryloxypropyltrimethoxysilane;
- and
- wherein the glass flakes have a concentration of at least 10% by volume within the second polymer.
