Abstract
Various implementations include a melt-spun filament (or fiber), a spinneret plate for producing the melt-spun filaments, and methods of making the melt-spun filaments. The melt-spun filaments have a similar soft hand feel as natural cotton fibers and are more resilient, less absorbent, and easier to clean, according to some implementations. In addition, according to some implementations, the melt-spun filaments produce a softer and bulkier yarn than traditional trilobal shaped filaments having the same denier per filament.
Claims17
A melt-spun filament comprising:
- an external surface and a central axis, wherein a cross-section of the external surface has a first perimetrical section, a second perimetrical section, a third perimetrical section, and a fourth perimetrical section;
- wherein the first and third perimetrical sections are spaced apart from each other and the second and fourth perimetrical sections extend between the first and third perimetrical sections and are spaced apart from each other;
- wherein the first, second, and third perimetrical sections are arcuate shaped and are convex as viewed external to each respective perimetrical section;
- and
- the fourth perimetrical section is arcuate shaped and is concave as viewed external to the fourth perimetrical section.
