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important in manufacturing such products as carpets which are constantly subjected to compressive strength which when withdrawn returns to their original standing position.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.

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:

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.
