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 at that each stage, samplings and controls are conducted and finally the product is graded and released in accordance with the test results.

در سال محققان دریافتند البسه ی حاوی لایکرا زیست سازگار نبوده و مشکلات زیست محیطی زیادی به همراه دارند. تاثیر منفی این الیاف بیشتر از سایر الیاف مصنوعی است.. الیاف مصنوعی دیگری نظیر نایلون از منابعی مانند نفت یا ذغال سنگ تهیه میشوند اما الاستان به صورت کامل در آزمایشگاه سنتز میشود. اگر برای تولید آن از منابع تجدیدپذیر است.فاده شود، مشکلات زیست محیطی آن کمتر خواهد شد.

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.

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.

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.
