Lenzing Modal FRESH - Artificial cellulose fiber with new functionality

Abstract

The general trend of our society towards ever higher hygiene standards and consumers' desire for greater comfort, especially when it comes to avoiding unpleasant odors caused by the growth of bacteria, have initiated the development of textiles with antibacterial properties. Traditionally, antibacterial properties are added to textiles in the finishing process, where an antibacterial agent is fixed to the surface of the knit or fabric. This process is not sufficiently resistant to washing and affects the surface properties, feel and appearance of the product, which reduces the comfort when wearing clothes. In order to solve this problem, synthetic fibers have been developed to which antibacterial agents are added. So Lenzing AG developed the modal fiber Lenzing Modal FRESH, which contains an agent to prevent the action of bacteria and control their growth on or in the fiber. It is a combination of the well-known properties of cellulose man-made fiber such as natural origin from renewable resources, softness and long-lasting freshness. Constant antibacterial action is achieved by adding a special additive to the spinning solution. The properties profile of the new fiber, its behavior in various processes in further processing, as well as the ability to produce mixtures with natural and artificial fibers are presented. Potential applications are discussed, eg for sportswear, T-shirts, pullovers, shirts and socks.
