Immunised Cotton

A chemically-treated cotton that resists ordinary cotton dyes, but has a marked affinity for basic dyes and some acid dyes. Fabrics in which this yam is used together with ordinary cotton yarns when dyed with direct or other cotton dye will give white effects on the immunised cotton, thereby yielding two-colour effects. The yarn can be used with wool, silk, linen, viscose, acetate and other fibres as effect threads. This chemical treatment produces a yarn differing greatly from ordinary cotton - the fibres shrink, lose lustre and become almost cylindrical.

This is a special yarn resulting from research work with immunised cotton and is prepared from immunised cotton fibre. Its properties differ from this immunised cotton or cotton. It has a strong affinity for direct cotton colours and acid dyes, and because of thise dyeing properties it may prove a valuable yarn, especially for the woollen industry (see Immunised Cotton)
