The multiplicity of nylon blends, processing systems, and uses requires a large variety of staple types. Tex per filament may be 0.1—2 (1—20 den), the cross section may be round or modified, the luster may be bright or dull, crimp may be present or absent, and the fiber may be heat-set or not, depending on its use. The staple length is about 4 cm for cotton system processing, 5—7 cm for the woolen system, 8—10 cm for the worsted system, and about 18—20 cm for carpet staple. 

Scouring may be conducted on jigs, boil-off machines, or kettles, depending on fabric weight, constmction, and crease tendency ia the rope form. A combination of a synthetic detergent and soda ash is usually used and scouring is conducted at 85—100°C. Certain nylon blends may require less stringent conditions and the use of less alkaline builders, such as tetrasodium pyrophosphate. 

The most popular coloration method is to apply the dyes continuously, usually by padding, but printing, spray jet, and droplet appHcations are used. In order to obtain patterned effects, chemical or physical resisting agents can be appHed first, and deep and normal dyeing nylon and basic dyeable nylon blends can be used. In the latter case the basic dyeable nylon is dyed with cationic dyes. Carpets can be printed in an analogous method to other textiles and this process is more popular in Europe than the continuous appHcation techniques used in the United States.

Nylon Blends. Differential dyeiag nylon types and cationic dyeable nylon blends are used primarily ia the carpet iadustry. The selection of cationic dyes for nylon is rather limited most products have very poor fastness to light. These blends are dyed ia a one-bath procedure at 95—100°C. Selected acid dyes are used for differential dyeiag. Disperse dyes will dye all different types ia the same depth. 

In the case of NBR-nylon blends it was reported that the addition of the curative m-phenylene-bis-male-imide, improved the strength and stiffness of the blend. An attempt to compare the effect of different curative...

Polyester Fiber-Nylon Blends. This fiber blend is used in apparel fabrics as well as in earpels. Disperse dyes dye both fibers, however they possess only marginal fastness properties on nylon. Therefore it is important to select those disperse dyes that dye nylon least under the given circumstances. The nylon is dyed with acid dyes, selected according to the fastness requirements. 

Fiber blending is a very common method of reducing the flammability of flammable fibers. Polyester is usually blended with cotton and this polycotton, if has lower than 50% polyester content can pass the simple vertical strip flammability test. With higher polyester content, sometimes the blended fiber is more flammable than the individual components. This is called wicking effect where the cotton acts like a wick, holding the polyester component together, which bums. Cotton-nylon blend are also quite commonly used to reduce flammability of cotton. 

Recent literature (72, 74) has indicated a considerable interest in blending ionomers (such as du Pont s Surlyn) with a variety of polymers. It is believed that an ionomer-nylon blend is the basis for a new engineering thermoplastic. 

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. 

Very effective retarding/migration aid for dyeing acrylic fibres with basic dyes, particularly recommended for use with K2.5 to K5.0 colours. Low blocking action ensures good exhaustion and the ability to overdye. No effect on softeners applied from dyebath. Acts as an antiprecipitant when dyeing acrylic/ nylon blends. 

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. 

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. 

Acid-dye leveling agent. Promotes on-tone buildup, controls barre, and migrates dye for best levelness in rapid dye cycles. Also compatibilizes acid and cationic dyes when cross-dyeing nylon blends. Recommended for all difficult nylon applications, especially automotive and carpet dyeing. 

Anionic napping softener for acetate, nylon, and acetate/nylon blends. Unlike conventional softeners, does not cause color bleeding onto labels and trim of stored garments. Gives full, lofty nap and a soft, silky nonscroopy hand. Nonyellowing, no effect on lightfastness.
