Product: Acrylic Fiber Staple

Description

Licensed by E.I. Du Pont De Nemour based in the US, Acrylic Factory # 1  has been producing Acrylic Fibers in Iran for three decades. The major monomers used in the production of acrylic fibers are acrylonitrile (AN), methylacrylate (MA) or vinyl acetate (VA). The acrylic fibers from Acrylic Fiber Factory # 1 are produced using Slurry Polymerization and Dry Spinning. The fibers from Acrylic Factory # 1 can be produced with a detex of 1.3-11 dtex and a cut length of 32-155 mm and can also be produced variously on a customized basis. The factory is also capable of producing microdenier fibers. Good tenacity and uniform dyability are among their other outstanding characteristics. The production technology as well as the overall, physical and mechanical characteristics of the fibers is such that they have placed them in the Dralon products by Bayer, Germany. The following are some of the characteristics of our product:

Production Process and Packaging

The advantage of Slurry Polymerization is its high flexibility such that the speed of polymerization is about 10 times that of Solution Polymerization and of a good efficiency. The presence of water in the reactive medium minimizes the difficulty of using the solvent. The polymer thus obtained possesses a higher molecular weight and a narrower PDI, improving the physical and mechanical properties of fibers, failure (=break) resistance (good tenacity and elongation) included. Of the unique benefits of the polymerization is the possibility to synthesize polymer without using dyable comonomer while the polymer obtained is capable of being chemically dyed. Of the advantages of Dry Spinning, reference can be made to the presence of microvoids in the fiber structure and its low porosity which improve its luster and make it feel much better. For this reason, too, the fiber longevity improves. Absence of microvoids makes fibers take longer to get dirty and faster to clean when washed. One characteristic of fibers produced by Dry Spinning is the Dog-Bone cross-sectional area. This characteristic adds considerably more to the tenacity and strength of the yarn produced than when other methods are used such that acrylic fibers can be used conveniently in high-speed carpet-weaving machines. Furthermore, owning to this very characteristic, the fiber resilience will increase. This characteristic is particularly important in manufacturing such products as carpets which are constantly subjected to compressive strength which when withdrawn returns to their original standing position. These characteristics have made Dry-Spinning fibers more valuable than fibers produced by other methods.  Produced in the spinning cells, the fibers are washed and then drawn proportionately to improve their mechanical properties. To make manmade fibers look like natural fibers, they are crimped and then cut to customized lengths. Next, they are heat-treated where they are fixed and dried. Finally, the product is packaged in covered polypropylene jutes and rod guards in bales weighing 300±۲۰ kg.

Use

These fibers are used alone or mixed with other fibers in the process of spinning and yarn production for use in textile, blanket and carpet industries.

Advantages

Uniform dyability, considerable durability, resistance to such environmental conditions as sunlight, high resistance to breakage (good tenacity and elongation), resistance to shrinkage, anti-static qualities, high luster and good manageability, considerable longevity, high strength yarn produced from these fibers, high resilience, takes longer to get dirty and is faster to clean when washed.
