Casual apparel manufacturer U-Right International Holdings has announced plans to invest up to $9 million in a new factory and research and development centre to explore the potential of nano-technology.

U-Right currently uses Swedish Texcote technology to protect its garments from damaging substances such as liquid, dirt and grime but is keen to develop its own nano-technology.

The firm's deputy chief executive, Raymond Chui, told The Standard newspaper its existing nano-technology garment plant was near capacity and a second production facility - which could boost capacity from 100,000 items to 200,000 garments a month - is set to begin operation next month.

He added it had set aside $6.4m for a third nano-technology clothing plant which could boost its capacity to one million garments a month.
