✦ Synopsis

The effects of tension, number of twists, and heat setting temperature on dyeing properties and the degree of crystallinity of nylon are examined. The amount of dyestuff adsorbed on stretch nylon decressee with tension but is not affected by number of twist, while the density is affected by neither of the above factors. The degree of twist fixing, crystallinity, and the amount of absorbed dyestuff increase with setting temperature. Factors such aa Betting temperature and tension are the main cause8 of uneven dyeing.

To help in achieving level dyeing in industrial applications dyestuffs are claasified according to their sensitivity to uneven stretch nylon 6 hosiery.
