Product: Polyester Poy (Polyester Yarn)
Description
Like other manmade fibers, polyester fibers are produced using industrial methods. Thanks to their characteristics they are good substitutes for such natural fibers as cotton. They are produced by combining dimethyl terephthalate, monoethylene glycol or terephthalic acid (substitute for the dimethyl terephthalate raw materials) in the presence of good catalysts. Titanium dioxide is used to produce a semi-dull product. Also, in the production process prior to packaging, the fibers are submerged in finish (0.4%). For such physical characteristics as the diameter and fineness of filaments, polyester yarn production and supply is customized. The chief application of texturized polyester yarn is filament-weft or circular yarns. The advantages of polyester yarn are:
- Shortened production process (compared to spun yarn)
- Increased production and
- Facilitated production process.

Production Process and Packaging
“Polyester” applies to a group of polymers where one group of esters lies in the main polymer chain. Although there are many polyesters, generally by polyester is meant polyethylene terephthalate (PET), the outcome of a chemical process with three reactors including dimethyl terephthalate and ethylene glycol (EG).
Picture 2 Control Room, Polymerizer Area
The polyester polymer produced in the Polymerizer Area is conveyed to the spinning machines where, using the metering pumps at the Spinning Area, it is further passed through packs to convert to filaments which are then sprayed with finish and supplied on 10-kg bobbins using bobbin winders. Finally, it is packed in 18 and 21-bobbin cartons.

Product: Polynite (PET-GF): Glass Fiber-Reinforced Polyester
Description
PET-GF Engineering Composite with a high molecular weight has a wide-ranging engineering application. As PET is reinforced with glass fiber, its mechanical, electrical, thermal and chemical properties as well as environmental, tolerance, creep, thermal expansion coefficient (like aluminum and brass) and, to a very large extent, extrusion capability improve. As the proportion of glass fiber and the production method (used in the production of extrusion parts and heat-deformable plates) vary, it has a wide range of applications. Among other things, it can be used in the production of household and automobile equipment requiring a high shock absorption structure, construction elements, case coating for such equipment as printers, copiers, cartridges, agricultural equipment including mowing machines, tractor engine cover, automotive spares, material transportation facilities such as palettes, crating, household equipment such as furniture as well as electrical and electronic equipment. Thanks to its very good dielectric properties, high thermal resistance and self-extinguishing characteristics, it is being increasing used in electrical, electronic, high temperature, spark-generation environments and direct-heat applications. Among other things, reference can be made to lamp-holders, cases and electrical sockets. Polynite is produced from polyester polymer compound combined with special-purpose glass fibers and other additives supplied in two versions: extrusion and compressive. The physical and chemical characteristics measured for the product are draw, bend, impact, pressure, MFI-IV and proportion of glass fibers.

Production Process and Packaging
Polyester polymer is produced by the esterification process with monoethylene glycol and dimethyl terephthalate in the presence of catalysts and at a particular temperature and pressure in a chemical process with three reactors at the Polymerizer Area.
Picture1 Control Room, Polymerizer Area
The end polymer produced with a high viscosity by polymerized is directed via a screw pump to the spinning machine made up of 64 positions where melt spinning is in progress. Then, for filtration and streamlining of polymer chains, polymer is carried in a uniform stream supplied by metering pumps to a series of packs.
Picture2. Spinning Machine, Diffusers and Polyester Fiber Finishers
Then, it passes the spinnerettes fitted beneath each pack, converting into super thin filaments. Still molten, the filaments passing the quenching air current blown by diffusers on the fibers, are cooled and when physically fixed, are emptied into cylindrical containers referred to as “cans”.

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.
