Use of leased workwear and rented consumer apparel has increased, and so have the demands on these textiles to have a long service life and retain protective or performance functions. Special attention should be paid to mechanical characteristics, color fastness, fit, comfort and washability. We consider all relevant aspects of suitability for leasing so you can document the quality of your textiles for your customers.
