تمامی این روش ها در مرحله ی اول شامل اینترکشن میان مونومرها به منظور تولید پلیمر است.. زمانی که پلیمر تشکیل شد، طی فرآیندهای مختلف الیاف تشکیل میشوند. هم اکنون بیش از . درصد از الیاف اسپاندکس در دنیا به روش خشک محلول ریسی (solution dry spinning) تولید میشوند.

PET-GF Engineering Composite with a high molecular weight has a wide-ranging engineering application. As PET is reinforced with glass fiber, its mechanical, electrical, thermal and chemical properties as well as environmental, tolerance, creep, thermal expansion coefficient (like aluminum and brass) and, to a very large extent, extrusion capability improve. As the proportion of glass fiber and the production method (used in the production of extrusion parts and heat-deformable plates) vary, it has a wide range of applications. Among other things, it can be used in the production of household and automobile equipment requiring a high shock absorption structure, construction elements, case coating for such equipment as printers, copiers, cartridges, agricultural equipment including mowing machines, tractor engine cover, automotive spares, material transportation facilities such as palettes, crating, household equipment such as furniture as well as electrical and electronic equipment. Thanks to its very good dielectric properties, high thermal resistance and self-extinguishing characteristics, it is being increasing used in electrical, electronic, high temperature, spark-generation environments and direct-heat applications. Among other things, reference can be made to lamp-holders, cases and electrical sockets. Polynite is produced from polyester polymer compound combined with special-purpose glass fibers and other additives supplied in two versions: extrusion and compressive. The physical and chemical characteristics measured for the product are draw, bend, impact, pressure, MFI-IV and proportion of glass fibers.

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:

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 the product can be transported in a -foot container. 

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.
