Promoted by Grasim Industries and local Thai entrepreneurs, Thai Rayon was incorporated in 1974. Thai Rayon is the pioneer as well as the sole manufacturer of viscose staple fibre (VSF) in Thailand and is listed on the Thailand Stock Exchange since 1984.

Thai Rayon commissioned two new production lines during the year 2009, and now has the capacity to produce 122,500mt of regular viscose fibre and 15,000mt of new generation cellulosic fibre – modal fibre of the highest standards. In January 2009, Thai Rayon also commissioned its 20,000tpa modern technology natural gas-based CS₂ plant, meant to cater to its increased requirement of CS₂ as well as to eliminate dependence on scarce wood charcoal.

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 32mm to 101mm, with lustre of bright bleach, semi-dull or full-dull. It also produces VSF for chlorine-free and anti-bacterial applications.

More than 60 per cent of Thai Rayon’s VSF throughput is directly exported to more than 20 countries worldwide. The VSF marketed under the brand Birla Cellulose meets the stringent quality expectations of customers in the US, China, Mexico, Europe, Turkey, Canada, Israel, Australia, South Korea, the Philippines, Indonesia, Pakistan, Bangladesh, Sri Lanka and the Middle East.

Thai Rayon also produces about 118,000tpa of anhydrous sodium sulphate as its by-product, which is widely used by the detergent, pulp, glass, leather and textile industries.

Thai Rayon is certified with ISO 9001 and 14001 accreditations and is also a recipient of the coveted TPM award. The company is also certified with the Oeko-Tex Standard 100, a textile industry certification of global testing and accreditation scheme for the screening of harmful substances within consumer textiles. Thai Rayon was rated as one of the best employers in Thailand by Hewitt Associates in 2005.

The company has significant investments in backward and forward integration projects in Thailand, Indonesia, Laos, China and Canada, as well as several diversification projects in Thailand and Egypt.
