Wool-nylon blends

Insect resist finishes are most commonly applied during dyeing. The best light fastness and wet fasmess properties are obtained when the finish is able to fully penetrate the fibres. When applying insect resist finishes to wool/nylon blends, care must be taken in the choice of the particular finish used. Chlorphenylid derivatives exhaust preferentially to nylon, leaving the wool fibres unprotected, whereas permethrin-based products distribute themselves more uniformly between the two fibre types. 

Blocking agent used to produce solid shades when dyeing wool/nylon blends. Also used in wool/viscous dyeing. 

Leveling agent for wool/nylon blends. Contributes to even exhaust.

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. 

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. 

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. 

CNC OPTIWITE L is a special optical white developed for use on lycra, nylon, acetate, and wool or blends of fibers. 

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

A semi-durable flame retardant application especially suited for wool, wool/nylon, wool/polyester blends. Laundering will remove this finish. 

Efficient leveling agent for nylon, wool, and blends, improves migration and even absorption of dyes. 

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. 

In addition to the garments prepared from woven fabrics, knits (especially single jersey and interlock) are also the major products suitable for garment finishing. The garments prepared from traditional natural fibres or their blends can be suitably processed in garment form. Some specialty fabric types such as blends of wool/nylon and wool/cotton have recently been processed in garment form in order to meet specific market demands of comfort and performance. 

SPS/nylon blends have been used to form bicontinuous, self-bulking fibers resulting from melt spinning joined melt streams, one of which comprises SPS, and the other a melt spinnable polymer other than SPS (e.g., nylon 66) [49]. More typically, SPS has been used as an additive in nylon 6 to form carpet fibers that match the morphology and hence the luster and softness of natural fibers such as wool. This technology is described briefly below.

Polyester fibers can be blended with natural fibers such as cotton and wool. The products have better qualities and are used for men s and women s wear, pillow cases, and bedspreads. Fiberfill, made from polyesters, is used in mattresses, pillows, and sleeping bags. High-tenacity polymers for tire cord reinforcement are equivalent in strength to nylon tire cords and are superior because they do not flat spot. V-belts and fire hoses made from industrial filaments are another market for polyesters.
