It is available in a variety of colors and is often packaged in cones. Some manufacturers make raw white, optical white, and dull viscose filament yarn.Viscose filament yarn is a type of fabric that can be used in many different applications. The primary ingredient in this type of fabric is viscose. There are many different colors that are available in this type of yarn. This type of fabric is also eco-friendly and biodegradable.Its production begins by reacting cellulose with caustic soda. This reaction results in a orange colored crumb. A further step involves the addition of carbon disulphide. This orange colored solution is then pumped through a spinneret to turn it into fine filaments. The process is then repeated to produce a wide range of colors.
After this, the cellulose is depolymerised and regenerates as fine filaments in a sulphuric acid bath.The fibers used to make rayon filament yarn are composed of wood, bamboo, and cotton pulp. These fibers are then spun into a yarn with cutting-edge technology. Its soft texture and breathable qualities make it a versatile product. Because it can be dyed in many different shades, there is a large market potential for this type of yarn.The processability of viscose filament yarn is determined by the tensile strength, elongation, and tenacity of the filaments. In addition, the viscose fibers undergo various purification and strengthening processes. Following washing and sizing, the filaments are subjected to a dilute solution of sodium sulfide to remove sulfur impurities.
The filaments are also bleached to remove any yellowness, which is necessary to obtain a white colour. Although viscose filaments are generally smooth, inelastic filaments, their physical appearance and chemical composition may vary with different processes and additives.The market for viscose filament yarn is divided into three regions.The Asia-Pacific region accounts for the highest market share of this product. Growth in the textile industry in Asia-Pacific has fueled the global viscose filament yarn market. In Asia, China dominates the market, exporting world-class viscose filament yarn to numerous countries. In India, Grasim is a key player in the viscose filament yarn industry, with a 43% share of the domestic market.
