BASF's Performance Chemicals for Textiles business unit is joining with Arch Chemicals to market Arch's Reputex 20 freshness-enhancing finish and its associated Purista brand label.

The companies will work together to enter new application sectors in everyday clothing and home textiles, such as shirts, fashion tops and bed linens.

Reputex is an antimicrobial treatment for cellulosic textiles such as cotton and cotton blends which makes textiles stay fresher for longer by controlling the growth of micro-organisms, which would cause odour and fabric deterioration during today's lower-temperature wash and wear cycles. 

"We wanted to join forces with a company that would strengthen our existing operations, making Purista treatment available throughout the global textiles chain and at the same time offering technical development potential," said Peter Cowey, international business manager - textiles for Arch.

BASF head of innovation textiles Dr Michael Schmitt added: "The freshness-enhancing treatment fits perfectly into our overall finishing product portfolio for the textiles industry.

"We can now offer customers additional functions together with our existing comfort enhancing finish. The benefits and strong position of the Purista brand opens up new market sectors, and brings BASF closer to the retailer and brand, as well as consumers."
