Title:
HIGH LOAD BEARING CAPACITY NYLON STAPLE FIBER AND NYLON BLENDED YARNS AND FABRICS MADE THEREFROM
Document Type and Number:
WIPO Patent Application WO/2010/042928
Kind Code:
A4
Abstract:
Disclosed is the preparation of improved high strength nylon staple fibers having a denier per filament of 1.0 to 3.0, a tenacity T at break of at least about 6.0, and a load-bearing capacity, T7, of greater than 3.2. Such nylon staple fibers are produced by preparing tows of relatively uniformly spun and quenched nylon filaments, drawing and annealing such tows via a two-stage drawing and annealing operation using relatively high draw ratios and then cutting or otherwise converting the drawn and annealed tows into the desired high strength nylon staple fibers. The nylon staple fibers so prepared can be blended with other fibers such as cotton staple fibers to produce nylon/cotton (NYCO) yarns which are also of desirably high strength.
