Wool-acrylic fiber blends, dyeing

Wool—Acrylic Fibers. This blend is being used for iadustrial and hand knitting yams. The acryHc fiber is aesthetically similar to wool, iacreases the strength of the yam, and adds bulk to the goods. Special precautions are necessary siace the two fibers are colored with dyes of opposite ionic type. Coprecipitation is prevented with the use of an antiprecipitant. Usually, level dyeing acid dyes are used for the wool portion in combination with the cationic dyes for acryHc fiber. 

REMOL ASN liquid has an excellent dispersing and compatibil-izing action in one-bath dyeing of wool or polyamide blends with acrylic fibers using anionic and cationic dyes and in dyeing polyester/acrylic fibers with disperse and cationic dyes. 

Is a strongly hydrophilic emulsifier, dispersant, solubilizer and detergent. It is used as a stabilizer and anticoagulant for natural and synthetic latices and dye pastes, as a dyeing assistant for wool/acrylic blends, and as a detergent and lubricant for fiber/fabric scouring. TRYCOL 5972 is also used as an emulsifier for waxes used in coating citrus fruits. HLB 15.8... 

Fibers used in the manufacture of apparel are predominantly cotton, wool, polyester, acrylic, and rayon. The fibers are used in both woven and knitted form with the exception of acrylic fibers, which are principally used for knitwear. Fiber blends are a feature of many items of apparel wear (e.g., polyester-rayon for corporate and evening wear, polyester-cotton for shirts, and polyester-wool for suits). Technologies for dyeing the two-fiber blends are well established. However, there can be some issues with effluent. 

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.
