For stripping and removing stubborn dye and colorant stains from washable fabrics, mild reducing bleaches or a dilute alkali (such as dilute sodium carbonate/ammonia solution) is standardly employed to solubilize, saponify, or chemically reduce acidic dye complexes without destroying the base textile fibers.

Self-help features in preschool children's clothing foster independence and self-reliance in dressing and toilet training. Prominent self-help features include:
Front openings with large zippers or large buttons (instead of inaccessible back openings)
Elasticized waistbands
Generous, loose armholes and necklines
Distinct front-and-back identification markers.

Cross dyeing is a piece-dyeing process used on blended or combination fabrics containing two or more distinct fiber classes with different chemical affinities (e.g., polyester and cotton, or wool and nylon). When immersed in a single dye bath containing two different dye classes (e.g., disperse dye for polyester and reactive dye for cotton), each fiber selectively absorbs its compatible dye and exhibits a distinct color, producing patterned multi-colored stripes, checks, or plaids in a single dyeing step. Both (A) and (R) are correct and (R) is the correct explanation of (A).
