Bleaching

A fabric finish as oxidative or reductive chemical treatment whitening fibers—the bleaching process on textile finishing, distinct from [[scouring|Scouring]] as related cousin and from [[optical-brightening|Optical brightening]] without bleaching naming.

How to recognize it

Bleaching shows bleaching as hydrogen peroxide or hypochlorite bath raising fiber brightness before color application.

Scouring is the related cousin finish. Optical brightening names a different textile process.

Origin and history

Textile surveys name bleaching among mill finishing steps.[1] Bleach documents bleaching on cotton.[2] Fabric-finish references contrast bleaching and related processes.[3] Mill photography documents bleaching reference.[4]

Bleaching reads on woven and knitted yardage before garment cutting.[2] Bleaching differs from related finish cousins.[1] Contrast with batch-39 fabric finishes mercerization sanforization calendering brushing singeing desizing on pre-dye mill preparation.[3]

Today bleaching appears on bleaching cotton prep, peroxide white shirting, pre-dye whitening, and optical base finishing in cotton and linen.[1][2] Mill control needs even temperature and tension.[4] When oxidative or reductive chemical treatment whitening textile fibers before dyeing—bleaching applies.[2]
