HUNTSMAN: whitening agent developed for cellulosics
A NEW fluorescent whitening agent that allows mills to achieve very high, brilliant and durable white shades on cellulosic fabrics has been developed by Huntsman Textile Effects. Labelled Uvitex BHA Liq., the high-affinity stilbene whitener has unequalled acid stability and acid fastness. That makes it a unique complement to most finishing treatments, with no risk of greening-off and superior protection against phenolic yellowing during storage and shipment. The company lists underwear fabrics among the products for which whitening is particularly challenging when other finishing effects are required.
The new whitener assumes particular importance as world supply of Tencel speciality cellulosic fibre is being raised considerably.
