Freudenberg NOnwovens (Germany), the world’s largest nonwoven fabric manufacturer, launched a new spunbonded filament microdenier spunlace nonwoven under the trade name Evolon in February 2000. Assembly line production. This proprietary process is its third major technological breakthrough in the production of nonwovens (the company claims to have produced the first batch of staple fiber nonwovens in 1948 and developed the first spunbond process in 1965).
Hermann Eidel, General Manager and Chairman of Freudenberg, said: "The one-step production process of the fabric is comparable to the multi-step weighing process required for woven and knitted fabrics. This feature plus the Evolo nonwoven production process includes compounding from polymer chips. After the filament is formed into a web, the composite fiber is split by the high-pressure spunlace process (each composite fiber can be split into several smooth microfibers) and the fiber web is consolidated (entangled) at the same time. The final production contains 0.05dtex-2.5dtex micro Fiber non-woven fabric. It is said that compared with conventional microfibers, the polymer in this process filament has higher molecular orientation.
Evolo spunlace non-woven fabric can withstand conventional water washing, which has higher in all directions Tensile strength, high tear resistance and good drape and feel. Evolo nonwovens are expected to target a wide range of durable goods and disposable products markets, especially the clothing market dominated by traditional textiles, including Sportswear, casual wear and work clothes for adults and children. For example, 70 g/m²-150 g/m² Evolo spunlace nonwovens can be used as T-shirts and sportswear.
