AI Technical Summary
Technical Problem
Existing filaments used for soil hiding lose their luster and become dull when exposed to higher temperatures, and they are not robust enough to maintain effective soil hiding properties.
Method used
A thermoplastic polymer filament with three lobes and a central void is designed, featuring specific geometric ratios and shapes that enhance soil hiding and durability, using a spinneret plate with hexagonal capillaries to produce the filament.
Benefits of technology
The filament maintains its luster over a wide temperature range and provides improved soil hiding due to light scattering and reduced surface area for soil adherence, while being durable.

Abstract
Various implementations include a spinneret plate defining a plurality of capillaries, including a first, second, and third capillary portions with a substantially hexagonal central area therebetween. The substantially hexagonal central area is joined to the spinneret plate by first and second legs being radially spaced apart and separate by a first apex of the substantially hexagonal area. A filament is formed by a polymer exiting the end of the capillary in three separate strands having the shape of the openings, and each strand bulges radially outwardly such that the strands merge together.
