Consistent with SNIA technology, the production process for this product starting with the mixing of monomers as feedstock 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 products but colored, super-white and antibacterial products are customized. The product is packaged in bales weighing ± kg and then put in covered polypropylene jute and rod guards. The bales measure ** mm. - tons of this product can be transported in a -foot container. 

Like other manmade fibers, polyester fibers are produced using industrial methods and because of their properties are good substitutes for such natural fibers as cotton. This product is made by combining dimethyl terephthalate, monoethylene glycol or terephthalic acid (substitute for the raw material &#;dimethyl terephthalate&#;) in the vicinity of good catalysts. Titanium dioxide is used to make the product look semi-dull. Also, in the production process, the product is submerged in finish (of about .%) prior to packaging. The following are some of the major characteristics of this product.

به عنوان ماده اولیه برای تولید زنجیر اصلی این پلیمر از دو نوع پیش پلیمر ماکروگلایکول انعطافپذیر (flexible macroglycol) و دی ایزوسیانات سخت (stiff diisocyanate) می توان است.فاده کرد. این ماکروگلایکول می تواند پلی است.ر، پلی اتر، پلی کرنات و یا ترکیبی از آن ها باشد. پلیمرهای مطرح شده پلیمرهای بلند زنجیر با گروه های هیدروکسیل در دو انتهای خود هستند و مهمترین ویژگی آن ها بلند و انعطاف پذیری آن هاست. دی ایزوسیانات دارای زنجیر کوتاه تری بوده و در دو انتهای خود دارای گروه ایزوسیانات است. و همین باعث سختی آن میشود و است.حکام زنجیر را به دنبال دارد.

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:
