NIR has been long used in the textile industry to differentiate fiber types for carpet recycling. Blend analysis of different polymers fibers can be analyzed with NIR. Real-time analysis of the application of PVOH sizing to warp yarn has been done with NIR on-line process analyzers.
Common fiber identified with NIR include: cotton/linen, merchandized cotton, acrylic, modified acrylic, acetate, triacetate, nomex, kevlar (29,49, and 129), nylon 6, nylon 6,6, silk, polyester, cationic and disperse dyeable polyester, polypropylene, PVA and PVC.
