Consistent with SNIA technology, the production process for this product starting with the mixing of monomers as feedback input to the reactors for polymer solution in Dimethylformamide (DMF) in the Chemical Area through to fiber production, drawing, finishing and packaging is continuous and that at each stage samplings and controls are conducted and finally the product is graded and released in accordance with the test results. Bright, dull and semi-dull products are normal. The product is packaged in bales weighing ± kg and then put in covered polypropylene jute and rod guards. The bales measure ** mm. - tons of the product can be transported in a -foot container. 

Anti-microbial fibers contain one or several activating agents capable of preventing the growth of or destroying microorganisms. Left in a polluted environment prone to microbial growth for a long time, antimicrobial fibers allow no microorganismic growth. In contrast, &#;Leef = a small rough cloth bag used as a sponge in the bath&#; left under similar conditions for some time would allow many microorganisms to grow on it. At Zayandeh Rood Fiber Company, there is also the customized option available to customer to order antimicrobial fibers with a variety of detexes. The fibers are used in blankets, socks, clothing, household textiles, hats, gloves, filters, sleeping bags, pillow covers, mattresses, etc. Our acrylic fibers are produced using monomer acrylonitrile as the major monomer (over %), methylacrylate or vinyl acetate as the second comonomer (less than %) and a third comonomer for dyability, by Solution Polymerization and Wet Spinning using SNIA technology. In both dull and semi-dull product, Titanium Dioxide (max .%) is used. Also, in the process of production, the fibers are submerged in finish (finish of about .%) prior to packing. The following are some of the major characteristics of our products:

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 (.%). 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:

The advantage of Slurry Polymerization is its high flexibility such that the speed of polymerization is about 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 ± kg.
