Abstract
Fabrics that are exhibit water repellency, abrasion resistance, and optionally flame resistance are described herein. The fabrics include a plurality of fibers (such as flame resistant fibers) and a finish that imparts water repellency and abrasion resistance to the fibers. The fabrics are free or substantially free from alkylfluoropolymers. Also described herein are garments including the fabrics.
Claims20
A water repellant and flame resistant fabric, comprising:
- a plurality of spun yarns comprising a plurality of flame resistant fibers;
- and
- a finish that imparts water repellency and abrasion resistance to the fabric, the finish comprising:
- (a) a water repellant agent selected from the group consisting of a hydrocarbon polymer and a silicone-based polymer, wherein the water repellant agent is present in the finish in an amount of 5% to 20% by weight on bath (% owb) and (b) a polymeric abrasion resistance aid, wherein the polymeric abrasion resistance aid is present in the finish in an amount of 5% to 20% by weight on bath (% owb),
- wherein the finish comprises less than 1 wt. % alkylfluoropolymers;
- wherein the fabric, before laundering and after being laundered five times in accordance with AATCC test method 135 (2018), has
- an abrasion resistance of at least about 500 cycles before a first thread break when tested in accordance with ASTM test method D3884 (2017) (H-18, 500 g on each wheel) and
- a water absorption of less than or equal to 15.0% as determined by NFPA 1971, 8.26 (2018).
