جوشکاری چرخشی در جوش قطعات پلاستیکی با سطح مقطع دایره ای کاربرد دارد، به این صورت که دو قطعه در تماس با هم قرار گرفته و روی هم می چرخند تا آنکه انرژی گرمایی لازم توسط اصطکاک برای ذوب سطح جوش ایجاد شود؛ سپس با توقف چرخش، محل جوش تحت فشار سخت شده تا جوش بین دو قطعه شکل گیرد. دستگاه های اتومات جوش چرخشی وجود دارند که در آنها پارامتر های جوش مانند زمان و فشار به دقت کنترل می شوند و کل فرایند خودکار انجام می شود و دقت و کیفیت بالایی دارند.
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.
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:

In textile industries, a major need is for a combination of different detexes of fibers to achieve optimal conditions for yarn production. Following numerous studies, to realize the customer-centeredness motto, Acrylic Plant # obtained the patent and production license for these fibers. Presently production of these fibers runs in two mixes of . and . detexes of % and % and that of mixed fibers run in . and decitexes of %. The major advantages of the combination and mixing of these fibers are:
