The versatility of this system is reflected in its suitability for blends of wool with other fibres [89]. The ideal conditions for the dyeing of wool/acrylic blends are at pH 4-5 and Albegal SET inhibits the risk of co-precipitation between Lanaset anionic dyes and basic dyes. Lanaset dyes are quite stable when dyeing polyester/wool at pH 4-5 and 115-120°C using Irgasol HTW (Ciba) as wool protectant. These dyes are also suitable for dyeing wool in its blends with silk, nylon or cellulosic fibres. 

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... 

The finishing of knitwear garments requires special attention to processing, as this will ultimately result in improved quality. The knitwear sector consists of a range of fibre and fibre blends. Wool is still possibly the most important section of knitwear production, followed by 100% acrylic and wool acrylic blends. Mohair, alpaca and cashmere have all figured into the production of knitwear, but essentially their production is relatively small compared to both wool and wool acrylic blends. 

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. 

AQUAFILM may be applied to cotton, rayon, nylon, polyester, acrylics, and wool and blends thereof. 

In the textile industry, yam spinning was one of the very first processes to be industrialized. Spun yams may contain a single type of fiber or a blend of various types. Combining synthetic fibers (which can have high strength, luster, and fire-retardant qualities) with natural fibers (which have good water absorbency and skin-comforting qualities) is very common. The most widely used blends are cotton-polyester and wool-acrylic fibers. Blends of different natural fibers are common too, especially with more expensive fibers such as cashmere. Yams are selected for different textile products based on the characteristics of the constituent fibers, such as wool for warmth, nylon for durability, cashmere for softness, etc.

Levelling agent and antiprecipitant for dyeing wool and nylon. Used when it is undesirable to have cationic levellers present or if carry over of traces of cations into subsequent treatments would be undesirable. It functions as an anti precipitant to enable acrylic/wool and acrylic/nylon blends to be dyed in a single bath. 

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.

The wide range of natural and man-made fibres provides many combinations to create new effects with desirable properties. Strength, wearibility and crease recovery are the main properties responsible for synthetic fibres becoming established for blends with cotton, viscose and wool. The acrylics are also in much demand for such blends, while polyamide fibres and triacetates are of secondary importance. 

Acrylic/wool blended fibre fabrics may be prepared according to established practice for wool, except that precautions are taken to allow for the thermoplastic properties for the acrylic fibres. Relaxation is done to remove the inherent strain. Worsted fabrics are crabbed and then scoured in either a Dolly at temperature not exceeding 40 C or in winch. 

Hydrogen peroxide is not suitable for acrylic fibre at highly alkaline condition and moreover acrylic fibre turns yellowish on alkaline peroxide treatment. The discolouration can be improved by after-treatment with formic acid in presence of detergent. Acrylic/wool blends can also be bleached by a reduction bleach or by combination of peroxide and reduction bleaching process. 

For acrylic/wool blends, the acrylic portion is brightened in the normal way and then the wool is bleached with hydrogen peroxide and subsequent reduction bleaching is done in a bath containing suitable brightener (1-2%) and stabilised sodium hydrosulphite (3-5 g/1) at 85 C for 30 min. The fabric is then rinsed and dried.

Acrylic residue with acrylic/wool blends The wool is dissolved with caustic soda as in method 2. 

Cellulose, wool, nylon or polyester residues in blends with acrylic fibres The fibre sample is treated at 90-100 °C for 1 h in dimethylformamide, preferably in a boiling water bath. The fibre residue is then extracted with fresh dimethylformamide for 30 min in the boiling water bath. It is then washed with 1-2 1 of hot distilled water and dried.

This process is used to recycle fabrics made from natural fibres such as cotton and wool as well as synthetic fibres including polyesters, nylons and blended fibres. Hawley (2006) describes the mechanical processing technique used in facilities in Prato, Italy, where acrylic textiles are shredded down to fibre. In hw example, acrylic garments were sorted and cut up, mechanically shredded to fibre, and then re-spun into acrylic yam for weaving into blanketing (Hawley, 2006). 

From 1960 to 1970, acrylic fiber consumption continued its rapid growth with a 19% increase in consumption worldwide, peaking at almost 2.1 billion pounds in 1970. Acrylics found wide use as a wool replacement fiber in carpets, home furnishings, and knitted apparel products. The world market share claimed by both acrylics and polyester increased sharply over this period primarily at the expense of wool and nylon. For acrylic, this increase was from about 14% of the world market in 1960 to approximately 23% in 1969. In the next decade, however, the growth rate decreased to around 8%. This was due primarily to the maturing of the wool replacement market in the United States. In addition, nylon became the dominant carpet fiber, reducing the acrylic market share from 25% at its peak to just 6% by 1976. Fibers and blends, such as polyester-cotton, also cut into the acrylic share of the synthetic fibers market. By 1980, the world market share held by nylon had fallen to approximately 30% from over 60% in 1960. Polyester now accounts for roughly 50% of the world market, while acrylics continue to hold approximately 20%.
