Acrylic yarn

Wet winding lubricant for acrylic yarns. Has no adverse effect on soft hand. 

Last rinse lubricant and softener for cotton, polyester/ cotton, acrylic and polyester/acrylic yarns. 

Effectively slows down the exhaustion of basic dyes on all types of acrylic yarns. 

POMOSOFT 54 Base is a highly concentrated cationic softener, designed primarily for use on acrylic yarn or fabric. It is a semi-soft waxy solid, and needs to be diluted before adding to the dye machine or pad bath. 

Several experimental approaches have been applied for determining the fiber Tg under hot wet conditions [199-203]. Aiken et al. [199] compared the Tg of a commercial acrylic yarn in the dry state and in water using dynamic-mechanical analysis, and observed a reduction from 92 to 72°C. Bell and Murayama [200] observed that the Tg of a commercial AN-NA copolymer decreased from 128°C when dry to 80°C in a 100% relative humidity atmosphere. Gur-Arieh and Ingamells [201] related the extension in length of Acrilan filaments to a Tg reduction and showed a shift from a 90°C in air to 57°C in water. Finally, Hori et al. [202] used DSC to show that the Tg of four kinds of acryhc fibers decreased with increasing water content and approached an almost constant value for all four fibers. 

Acrylic fibers are mostly sold as stable and tow, though a small amount of continuous filament is also produced. Acrylics are restricted to staple yarn processes because a good method for texturing a continuous filament acrylic yarn has not been devised. Successful texturizing requires that the fiber be partially melted while the yarn is twisted. This is not possible with acrylic fibers because they do degrade rather than melt. 

Synthetic cellulose yams were developed between 1880 and 1910, first from a nitrocellulose solution, and later as copper rayon and "viscose rayon . The cellulosics are often called half-synthetic because the raw material is a natural polymer. The most important fully synthetic yarns were developed between 1935 and 1942 - polyamides (PA66, PAG), polyester (PET), and acrylic yarns (PAN copolymers). Another half-century later, many high-performance fibers were introduced, for example aramid (PPTA), gel-spun polyethylene, and carbon fiber.

Acrylic fibers generally have good hand, as its called in the business (they re soft). They resist creasing, and they are quick to dry. Acrylics have replaced wool in many applications, such as blankets and sweaters. Because of their unique bulking characteristics, they take on the appearance of wool yarn. 

Acrylic fibers are used as an alternative to wool for sweaters. PAN is also used in the production of blouses, blankets, rugs, curtains, shirts, craft yarns, and pile fabrics used to simulate fur. 

Composite objects like this Hopi Kachina may contain many different materials. This doll is made of cottonwood root, decorated with paint, fabric, feathers, metal, plastic, and hair. Pahlik-mana (butterfly maiden) kachina c. 1980. Cottonwood root, acrylic paint, wool garments, feathers, yarn, plastic (artificial plant in right hand), metal (sequins, necklace), artificial pearl, down feathers. 

Softening agent and antistatic processing aid for most fibres but particularly suitable for use on acrylics. It is stable to basic dyebath conditions and can therefore be applied to acrylic fibre or tow during dyeing giving a simple economical processing route for conversion into yarn. 

A range of preblended sizes to satisfy any staple yarn requirement at a reasonable cost. The products are free flowing powders based on acrylic and other vinyl polymers blended with starch. Wax is included in appropriate products. 

Lubricant and antistat for the processing of synthetic fibres and their blends. Improved fibre control gives level yarns, less fly waste and fewer roller laps. Excellent results have been achieved in open-end spinning of acrylic fibres treated with ALCOSTAT L where a marked reduction in accumulated trash was noted. Good non-yellowing properties make it particularly suitable for use on propylene.
