POLY SHEEN® has a much larger surface area to reflect the light, which is why it shines so beautifully. It also has better elastic qualities and 50% higher tensile strength than rayon. POLY SHEEN® can be used in every situation and is particularly well suited for use with highly stressed textiles such as sports and leisurewear, childrend's clothes, leather, work clothing, jeans, terry cloth, catering and hospital laundry.
