Thai Acrylic Fibre, the flagship company of India's Aditya Birla group, is sailing against the global tide with an investment of two billion baht in a new extension at its factory. The money is to fund an increase in production capacity next year, with 100 employees to be added to the existing workforce of 443. Annual production capacity at the company's acrylic fibre plant in Sara Buri will increase by 30 per cent to 74,100 tons as a result.
