Cationic cellulosic fibers and methods of making and using the same

A method of producing a garment from a ring dyed core yarn, comprising:

• preparing a cationic cellulosic fiber comprising the steps of:
• treating an outer layer comprising a plurality of covalently attached cationic moieties, wherein the cationic moieties are derived from a quaternary ammonium salt;
• and
• leaving an inner layer that is substantially free of cationic charge after the treating step;
• weaving the cationic cellulosic fiber into an undyed cationic fabric;
• shaping the undyed cationic fabric into:
• a substantially colorless garment;
• and
• cut-and-sew waste;
• dyeing the substantially colorless garment with an anionic dye;
• and
• reprocessing the cut-and-sew waste into an undyed cationic yarn.

A cationic cellulosic yarn comprising:

• an outer layer comprising a plurality of covalently attached cationic moieties;
• and
• an inner layer that is substantially free of cationic charge,
• wherein the plurality of covalently attached cationic moieties gradually decreases through a thickness of the outer layer toward the inner layer, and wherein the cationic moieties are derived from a quaternary ammonium salt.

An anionic dyed cellulosic yarn comprising:

• a surface layer of the yarn absorbing the largest proportion of the anionic dye;
• an inner core of the yarn absorbing none of the anionic dye;
• and
• a gradation layer of the yarn between the surface layer and the inner core, wherein the gradation layer absorbs a varying amount of the anionic dye depending on the distance from the surface layer.
