Wool-nylon fiber blends, dyeing

Wool-Nylon. Nylon has been blended with wool in order to give additional strength to the yarn or fabric, it is used mainly in tbe woollen industry for coats and jackets and, to a lesser extent, for socks and carpet yams. Both fibers are dyed with the same products, however the fibers have different affinity to them. Generally level dyeing acid dyes are applied. 

REMOL GES Liquid is an efficient leveling agent to be used in dyeing of nylon fibers and wool as well as their blends. 

Capracyl [Du Pont], TM for a group of neutral-dyeing, premetalized acid colors that produce the highest possible degree of lightfastness on nylon. Also suitable for dyeing wool, particularly in blends with cellulosic fibers. 

For over a decade NIR quality control has been used in the textile and fiber industries. Perhaps the widest use of NIR has been in the cotton industry. Cotton blending, mercerization, and fiber maturity measurement have been used offline for rapid process control. The wool industry has also employed NIR to measure the residual grease after scouring. Calibrations have been developed for measuring moisture and heat set temperature in nylon yam. Online NIR analysis is being developed for the quality control of the dyeing procedure for carpet yam and for measuring yarn diameter. 

Uses Antiprecipitant used in dyeing acrylic fibers and blends with wool and nylon where cationic and anionic dyes are used simultaneously Properties Amber liq. misc. with water 43% act.
