In July 2001, the Zwick Roellcompany group was converted into a stock corporation: the Zwick Roell AG. Part of this stock corpo- ration are the companies Zwick, Roell Amsler, Toni Technik, Indentec Ltd. and Acmel Labo. These companies supply an extensive program for materials, component, and functional tests - from the manually operated hardness tester up to a complex test system for the process-accompanying application.Zwick has many years of experi-ence, combined with a multitude of supplied systems. This experience is continuously supplemented by the constant communication with the users. On this solid basis, the company supplies a wide range of high-performance products – from the economical standard machine up to special versions and designs for special test jobs. Modern mechanics, high-performance electronics and the application- oriented software are the prere- quisite for the versatility and the high “intelligence” of these modern industrial testing machines and systems.However, the services of the ZwickRoell AG go far beyond the supply of products. Already in 1994 the company received the certification according to DIN EN ISO 9001 and thus guarantees a consistently high product and service quality. With accredited DKD Modern textiles, however, are high- tech products that do not have very much in common any more with these basic functions. In specific material compositions they offer qualities we did not dare dreaming of a few decades ago. Here are a few examples: As garments they can be waterproof, impermeable and breathable at the same time, they can have warmth-giving- and warmth-regulating and recovering qualities (so that e.g. a crease stays unharmed even after washing and dry-cleaning) or they can have tearproof qualities. As safety clothing they protect the wearer against heat and flames, dangerous tools as for example chain industrial saws and even against shots from small arms. In conveyor belts and tires they are used as reinforcement. As climbing ropes they are light and have high strength, at the same time they are elastic to control the

Already in 5000 B.C. cloths were woven in Egypt. For this purpose the people used natural raw materials such as cotton, flax fibres, animal hair and silk threads. The people used them as garments and as protection from the cold. As textiles for the home, they made living and work rooms look nicer. can be waterproof, impermeable
