Thai Rayon

Thai Rayon, promoted by Grasim Industries Limited, India, an Aditya Birla Group company, and local Thai entrepreneurs, is the pioneer as well as sole manufacturer of Viscose Staple Fibre (VSF) in Thailand. The company was incorporated in 1974, and is listed on the Thailand Stock Exchange since 1984.


Almost two-third of Thai Rayon's VSF production is directly exported to more than 20 countries worldwide. The company’s products under the umbrella brand of Birla Cellulose, meet the stringent quality requirements of customers spanning six continents from the Middle East to Europe and from USA to Asia Pacific. Thai Rayon produces a wide range of fibres that have multiple functional benefits such as soft feel, high moisture absorbency, bio degradability, comfort and fashion. These fibres have various applications in apparel, home textiles, dress material, knitwear, wipes, personal hygiene, and medical usage.

Thai Rayon has diversified into a new generation fibre -- Birla Modal, which is widely used in high-end textile fashion products. Thai Rayon also produces anhydrous sodium sulphate as its by-product, mostly used in detergent, pulp, glass, leather and textile industries.

With its five flexible VSF production lines, Thai Rayon caters to the demands of both textile and non-woven applications, producing VSF varieties in the range of 0.8 to 5.0 denier, staple lengths in the range of 32 mm to 101 mm, in bright bleach, semi-dull or full-dull luster, as well as in chlorine-free and anti-bacterial applications.

Thai Rayon also produces about 85,000 tpa of anhydrous sodium sulphate as its by-product, which is widely used in domestic market by detergent, pulp, glass, leather and textile industries. 

Starting with a small capacity of 9,000 tpa, the company has come a long way in achieving a capacity of 140,000 tpa of VSF. The company contributes significantly to the economy of Thailand.
