Antistatic nylon fiber

An anionic leveling agent for use in space dyeing nylon fibers to prevent frosting. Excellent for use with hard to level antisoil and antistatic nylon fibers,... 

Antistatic and conductive nylon fibers with improved performance and durability can be prepared by spinning. Since most of conductive additives are inoiganic particles, conductive fibers are generally obtained by composite spinning. However, antistatic nylon fibers are laigely produced by blend spinning because lots of antistatic additives are organic materials. 

Bicomponent technology has been used to introduce functional and novelty effects other than stretch to nylon fibers. For instance, antistatic yams are made by spinning a conductive carbon-black polymer dispersion as a core with a sheath of nylon (188) and as a side-by-side configuration (189). At 0.1—1.0% implants, these conductive filaments give durable static resistance to nylon carpets without interfering with dye coloration. Conductive materials such as carbon black or metals as a sheath around a core of nylon interfere with color, especially light shades. 

A simple and convenient method of polymer modification is to introduce an additive. This method is most effectively utilized in the modification of nylon fibers. For antistatic and conductive properties, hygroscopic polymeric materials and conductive materials such as carbon and metal powders are incorporated, respectively. For flame retardant properties, antimony trioxide is added. To impart ultraviolet shielding properties, ultraviolet absorbents are included and inoiganic particles of metal such as silver and zeolite containing metal ions are used for antibacterial and odor preventing properties. 

A nylon fiber whose surface was coated with carbon particles in the finishing stage was reported to have antistatic properties[93]. The substrate fiber had a composite structure of core-sheath, whose core and sheath were composed of copolymer of nylon-6 and nylon-6,6 and low temperature melting nylon-6,6,... 

In blend spinning, a continuous filament of antistatic substance at least 25 to 50% of the fiber diameter should be formed throughout the fiber. An increase in molecular weight of poly(alkylene oxide) component improved antistatic performance but lowered heat resistance. It was reported that a nylon fiber in which long and thin filaments of poly(ether ester amide) were formed by blend spinning showed good antistatic propeilies.

Gantrez AN resins and other alkyl vinyl ether-MA copolymers have had extensive examination in paper coatings, textile sizing, leather treatment, and other applications, as shown in Table A.4. Durable antistatic coatings for Nylon fibers have been prepared. The copolymers have also been examined as binders for explosives and modifiers for Ag20-Zn cells. 

Uses Lubricant, emulsifier, and antistat for polyester and nylon fibers In textile spinning processes... 

Over time, finish components tend to separate and migrate within the fiber and throughout the yam package. With nylon, the ionic emulsifiers and antistats tend toward the core of the fiber whereas the hydrocarbon lubricants remain on the surface. It is, therefore, essential to scour yams and fabrics at neutral to basic pH to reemulsify the lubricant and remove the finish emulsifier prior to dyeiag. In formulating any new finish, environmental issues such as biodegradabihty, water and air pollution must be considered (137). 

Antistats such as polyoxyethylenes (151,152) and A/-alkyl polycarbonamide (153) are added to nylon to reduce static charge and improve moisture transport and soil release in fabrics. These additives also alter the luster of fiber spun from bright polymer. Static reduction in carpets is achieved primarily by the use of fibers modified with conductive carbon black (see Antistatic agents Carbon, carbon black). 

Amine salts of a-sulfonated fatty acids and esters are also used as antistatic agents. Mixtures of alkyl a-sulfo fatty acid ester diethanolamine salts and hexa-decyl stearate or butyl stearate are coated onto nylon yarn after fiber formation and before stretching [97]. Polypropylene can be made antistatic with an amine salt of a-sulfolauric acid [C10H21CH(SO3Na)COO +NH(CH2CH(OH) CH3)3] [98]. 

BURCOVEL C may be used on a wide variety of natural and synthetic fibers and blends Including cotton, nylon, polyester, acrylics, and polyester/cotton blends. It provides excellent softness, lubricity, and drapability. It has good resistance to discoloration from heat, ageing, and ultraviolet light. Unlike many other cationic softeners, it does not reduce the absorbency of fabrics treated with it. BURCOVEL C imparts antistatic and antidusting properties as well as softness. 

CNC Antistat C New represents a durable antistatic product which is particularly effective on typical problem fibers such as nylon, orIon and dacron. Very small amounts applied to these materials will attach so tenaciously that repeated laundering and dry cleaning will not remove the finish. CNC Antistat C New is substantive in nature and, therefore, has a strong affinity for these fibers. 

CNC SCROOP is an ethylene oxide condensate which produces an excellent scroop in rayon, nylon acetate and orIon piece goods yarn or stock. This product also is an outstanding antistatic agent and fiber lubricant. 

Durable antistat for nylon and other synthetic fibers blended with containing cellulosics. 

Cationic softener and antistat for acrylic fibers, yarn, knitgoods and nylon carpet. 

A versatile fiber lubricant recommended for processing nylon and polyester fibers. It has an excellent balance of fiber-to-fiber and fiber-to-metal lubrication and good antistatic properties. PROGALUBE 339 also prevents buildup of monomer on pin-drafters and spinning frames.
