Definitions
- the present disclosure relates to flame resistant fabrics made from yarns comprising cellulose fiber, polyamide fiber, and oxidized polymeric biregional fiber.
- Flame resistant garments are worn by workers exposed to thermal and flame hazards in the workplace such as heat, open flame, and electric arc flash to reduce potential bodily injuries.
- 88/12 fabrics comprising a blend of 88% cotton fibers and 12% nylon fibers.
- the fabrics are typically treated with phosphorous-based flame retardant chemicals.
- the fabrics meet the industrial standards of flammability performance requirements. Further, because the majority of the fabric comprises cotton fibers, the fabrics are relatively inexpensive. In addition, these fabrics are more durable during industrial laundering and wearing as compared to 100% cotton fabrics since addition of nylon fibers to the fabric provides a significant improvement in abrasion resistance of the fabrics.
- the 88/12 fabrics are commercially available at a weight of approximately 220.4-0237.34 g/m 2 or more.
- One example of an 88/12 fabric is UltraSofot® fabric produced by Westex Inc, an entity of Miliken and Co.
- inherently flame resistant fibers such as meta-aramid fibers, commercially marketed as Nomex® fibers by Dupont Company, are used for light weight flame retardant fabrics.

Further, some embodiments of these light weight fabrics can be dual certified fabrics for both the NFPA 70E HRC level II and NFPA 2112 (2012).
- the articles include, but are not limited to apparel, shirts, pants, jackets and coveralls.
- Fabric sample 1 is an embodiment of the current invention.
- Fabric samples 2 and 3 are comparative examples. All three fabric samples were woven fabrics having a twill construction.
- Fabric sample 1 was woven with yarns comprising 47 weight % natural cellulose fiber, 14 weight % FR rayon fiber, 16 weight % polyamide fiber, 6 weight % para-aramid fiber, and 17 weight % oxidized polymeric biregional fiber.
- Fabric sample 1 comprised warp yarns comprising the natural cellulosic fibers and the polyamide fibers, and filling yarns comprising the FR rayon fibers, the polyamide fibers, the para-aramid fibers and the biregional fibers.
- Fabric sample 2 is a baseline fabric for comparison with fabric sample 1. Fabric sample 2 was woven with the same filling yarns, but different warp yarns when compared to fabric sample 1. Fabric sample 2 comprised 35 weight % FR rayon fiber, 2 weight % polyamide fiber, 15 weight % para -aramid fiber, 29 weight % modacrylic fiber and 19 weight % oxidized polymeric biregional fiber.
- Fabric sample 3 is another baseline fabric for comparison with fabric sample 1. Fabric sample 3 was woven with the same warp yarns and different filling yarns when compared to fabric sample 1. Fabric sample 3 comprised 88 weight % cotton fiber and 12 weight % polyamide fiber. Table 1.

- HTP Heat Transfer Performance
- ATPV Arc Thermal Performance value
- Table 2 lists test results for fabric samples of Example 1.
- Fabric sample 1 was woven with the same filling yarns and different warp yarns with fabric sample 2. Fabric sample 1 was made with more cellulose fibers, including additional cotton fibers and less para -aramid fibers than fabric sample 2. The ratio of ATPV to fabric weight of fabric sample 1 (1.72) was much higher than that determined for fabric sample 2 (1.21). Fabric sample 1 is woven with the same warp yarns and different filling yarns with fabric sample 3. About 17% by weight oxidized biregional polyacrylonitrile fibers were included in fabric sample 1, which resulted in the higher ratio of ATPV to fabric weight of fabric sample 1 (1.72) than was determined for fabric sample 3 (1.23).
- the fiber blend used for fabric sample 1 makes it possible to make a light weight cotton/nylon/ oxidized bioregional polyacrylonitrile blend fabric treated by flame retardant chemicals that meet the performance requirements on the electric arc rating for HRC level II in NFPA standard 70 E (2012).
