Freudenberg NOnwovens (Germany), the world's largest nonwovens manufacturer, launched a new type of spunbond filament microdenier spunlace nonwovens with the trade name Evolon in February 2000. Single assembly line production of web and spunlace. The proprietary process is its third major technological breakthrough in nonwoven production (the company claims to have produced the first staple fiber nonwovens in 1948 and developed the first spunbond process in 1965). Hermann Eidel, Managing Director 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 combined with the Evolo nonwoven production process includes laminating from polymer slices After the filament is formed into a web, the composite fiber is split by a high-pressure hydroentanglement process (each composite fiber can be split into several smooth microfibers) and the fiber web is consolidated (entangled) at the same time, ultimately producing a micro fiber web containing 0.05dtex-2.5dtex Fiber nonwovens. It is said that the polymer in the filaments of this process has a higher molecular orientation than conventional microfibers. Evolo spunlace nonwovens can withstand regular washing and have higher molecular orientation in all directions. Evolo nonwovens are expected to target a wide range of durable and disposable product markets, especially the apparel market where traditional textiles dominate, including Sportswear, casual wear, and workwear for adults and children. For example, Evolo spunlace nonwovens of 70 g/m2 to 150 g/m2 can be used for T-shirts and sportswear.
Freudenberg currently has. An Evolo pilot production line is in operation. The company said that an industrial production line was put into operation at the Colmar plant in France in the summer of 2000, and it plans to put another Evolo production line into operation in 2002.
