Viscose Yarn

Viscose is a man-made fiber- recycled fiber- and is the most important member of the Rayon’s fibers family. The raw material used for production of the viscose fibers are cotton linter and wood cellulose (mainly trunks of forest trees), which is a disadvantage of the viscose fibers since it damages the environment. The cross-section of viscose fiber is wavy and with lengths similar to cotton, linen, and wool fibers. The diameter of the viscose fibers varying from 12 to 22 microns depend on the diameter of the holes on the spinnerette (the viscose fibers spinning by passing through spinnerette).
Rayon viscose is made up of natural cellulose such as woods, or cotton linters containing 87-98% alpha-cellulose. After washing the raw materials with boiling alkali and bleaching it with sodium hypochlorite, It is spinnable fibers. The only difference between viscose fiber (Rayon) and cotton and linen is that viscose fiber (Rayon) is similar to paper – a homogeneous paste produced of wood cellulose which is processed to the final product. Fabrics produced of rayon fibers have a relatively high moisture absorption (in some cases up to 50% more than cotton), great breathability, great comfortableness, and favorable dyeability. The low electric charge and good resistance to gutting (called in Persian taltal) are other desirable properties of rayons. Production Method:
All natural materials that have cellulose are good to make viscose fibers. Most of the trees’ lumbers, sugar cane, rice and wheat straws, are always used for viscose fibers production. In different stages raw materials convert to a special paste with a limited amount of impurities, and then converted to fibers after passing through the sppinerette and the coagulation bath. The recent research on the viscose fibers has improved the strength of the fibers. Unlike cotton, increased moisture content reduces durability of viscose fibers, but increases dyeability. In the standard condition, viscose fibers have 12% moisture absorption compare to 8% of cotton fibers. The viscose fibers have less elasticity than cotton fibers, which make it more wrinklable. As the smoothness of the viscose fiber surface, it is brighter than cotton fiber; however, boiling water eliminates its brightness. The viscose fiber resists up to 150 degrees Celsius, but it is still changing color in expose to the sunlight. Similar to cotton, acids cause viscose degradation, but it shows great resistance to alkalis. The length of the viscose fiber is shorter and weaker than cotton. The viscose thermal properties are similar to cotton, yet less than cotton fibers with good ironing properties. Since synthetic fibers do not show wrinkles, waves and folding, they must be modified by chemical and mechanical methods to resemble more natural.
Application of Viscose Fiber: it is used for clothing includes: Blouse, Shirts, women’s clothing, linings, underwears; industrial textiles; non-woven textiles; and synthetic chamois leather; Home Usage such as: Roofing, Pillowcase, Sheets and Handbags.

International Standards

All types of viscose yarn are produced under the highest global standards, using the best quality raw materials. Raw materials have gone through testing of the quality in the well-equipped laboratories. The quality control of the final products, optimization of production process, and transportation as well as packing processes have been in accordance with global standards to increase efficiency, waste reduction, and ultimately manufacturing of a product which is compatible to the needs of the target market.

Advanced Manufacturing Technology

The latest technology and modern machinery from the well-known and the best international companies to set up advanced lines of the viscose yarn production. Mechanized machines with the least human intervention in the production lines has minimized human error and has produced less waste in the production lines.

Diversification Of Production and Customization

Viscose yarns have been produced with different characteristics to support the different market needs, different usage in the various industries. The possibility of production for customized viscose yarns based on the specific needs of customers and business partners is also available.

Competitive Prices Compare To Our Rivals

Viscose yarn prices vary according to different criteria, such as the type and quality of raw material used in the production of yarn, or the volume of the order and the type of order. The specific characteristics of viscose yarn are directly influenced by the customer’s demand. However, considering the global competitors of this industry, keeping prices competitive while the high-quality of the yarns are retained is one of the main advantages in this market.

Needs Assessment And Manufacturing Of New Products

Having a research and development department in order to take advantage of the recent knowledge of the viscose yarn production in one hand, and the needs assessment for global markets to produce viscose yarn according to the customers’ attitude and the demands of the business partners for the final products on the other hands, direct us toward the sustainable and continuous development of production lines to get more shares of the target market.
