  • Publication number: 20230272556
    Abstract: High strength or load bearing nylon fiber with break tenacity greater than 7.5 g/den and/or a tenacity at 10% elongation of greater than 4.0 g/den as well as yarns, fabrics and articles of manufacture thereof and methods for their production are provided.
    Type: Application

    Publication date: August 31, 2023
    Inventors: Douglas A. Bloom, Cynthia Dawson Mcnaull
  • Publication number: 20200283933
    Abstract: Nylon staple fiber with additive exhibiting a break tenacity greater than 6.5 g/den are provided as well as yarns, fabrics and other articles of manufacture produced from the fiber. Methods for producing the nylon staple fiber with additive are also provided.

  • Patent number: 10619272
    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.

  • Patent number: 10072365
    Abstract: Knit fabrics and military apparel such as T-shirts made therefrom are disclosed. The fabrics are constructed from blended yarns made from an intimate combination of nylon and cotton staple fibers. Such fabrics comprise a weight ratio of cotton to nylon which ranges from about 55:45 to about 85:15, and these fabrics also have a weight ranging from about 3 to about 8 oz/yd2. Knit fabrics of this type possess a desirable combination of good thermal protective properties, provided the specified high level of staple fiber blend uniformity is achieved, along with very useful abrasion resistance, bursting strength and drying time characteristics.

  • Publication number: 20110177737
    Abstract: Included is the preparation of high strength nylon staple fibers having a denier per filament of about 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 about 2.5, including greater than 3.2. Such nylon staple fibers are produced by preparing tows of relatively high molecular weight nylon filaments (RV of 65 to 100), drawing and annealing such tows via a two-stage drawing and annealing operation 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 a companion fiber such as cotton staple fibers to produce nylon/cotton (NYCO) yarns.
