Abstract
Flame resistant fabrics and garments that have improved resistance to pilling and/or abrasion are disclosed. The fabrics, the fibers or yarns that make up the fabrics, or garments made from the fabrics are treated with a finish composition that is applied to the fibers, yarns, fabrics, or garments and then cured. The finish composition increases the resistance to pilling and/or abrasion of the fibers, yarns, fabrics, or garments. The finish composition includes a polymeric abrasion resistance aid, an alkylfluoropolymer, a polyethylene, and a wetting agent.
Claims33
A flame resistant fabric comprising:
- a plurality of spun yarns comprising a plurality of inherently flame resistant fibers, the plurality of inherently flame resistant fibers comprising at least one of meta-aramid fibers, para-aramid fibers, polybenzimidazole fibers, polybenzoxazole fibers, melamine fibers, polyimide fibers, or polyimideamide fibers;
- and
- a finish that imparts abrasion resistance to the fabric, the finish comprising a polymeric abrasion resistance aid and an alkylfluoropolymer,
- wherein the fabric, before laundering and after being laundered five times in accordance with AATCC test method 135 (2006), has an abrasion resistance of at least about 1000 cycles before a first thread break when tested in accordance with ASTM test method 03884 (2007) (H-18, 500 g on each wheel).
A flame resistant fabric comprising polybenzimidazole fibers, wherein the fabric comprises a finish that imparts abrasion resistance to the fabric, the finish comprising a polymeric abrasion resistance aid and an alkylfluoropolymer,
- wherein the fabric, before laundering and after being laundered five times in accordance with AATCC test method 135 (2006), has an abrasion resistance of at least about 1000 cycles before a first thread break when tested in accordance with ASTM test method D3884 (2007) (H-18, 500 g on each wheel).
