Polybest fibers are acrylic fibers replacing asbestos in the preparation of concrete, asphalt, corrugated false ceiling, etc. The cut lengths of this fiber ranges from to mm and their physical and chemical properties differ from those of standard fibers and customized fibers are also produced. The acrylic fibers needed for these products are produced by solution polymerization, wet spinning and SNIA technology using monomer acrylonitrile as the major monomer. Production of this fiber used in industry ranges from . to . dtex and a length of - mm.

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:

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:

در حال حاضر، خط اکستروژن ورق پت تهویه‌شده بدون خشک‌کن دوقلو که توسط Suzhou Jwell راه‌اندازی شده است.، می‌تواند تکه‌هایی را با حداکثر محتوای آب اولیه ppm پردازش کند. علاوه بر این، افت ویسکوزیته در داخل . دسی لیتر بر گرم کنترل می شود.

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. 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.
