Abstract
Industry 4.0 applies to the knitting industry. Regarding the knitting process retrofitting activities are executed mostly manually by an operator on the basis on the operator's experience. In doing so, the knitted fabric is not necessarily produced in the most efficient way regarding process speed and fabric quality aspects. The knitting division at ITA is concentrating on project activities regarding automation and Industry 4.0. ITA is working on analysing the correspondences of the knitting process parameters and their influence on the fabric quality. By using e.g. the augmented reality technology, the operator will be supported when setting up the knitting machine in case of product or pattern change - or in case of an intervention when production errors occur. Furthermore, the RFID-Technology offers great possibilities to ensure information flow between sub-processes of the fragmented textile process chain. ITA is using RFID-chips to save yarn production information and connect the information to the fabric producing machine control. In addition, ITA is currently working on integrating image processing systems into the large circular knitting machine in order to ensure online-quality measurement of the knitted fabrics. This will lead to a self-optimizing and selflearning knitting machine.

The requirements for the manufacturing companies are very complex

Why should the Industrie 4.0 approach be applied to the textile industry? A survey carried out by Fraunhofer-Institut für Arbeitswirtschaft und Organisation (IAO) in 2013 show that 98,6 % of the respondents of German textile machinery manufacturers and fabric producers announced that flexibility in production will be one of the parameter of maximum significance for their future success
Summary
Industry requires short response time and more efficient systems in order to remain internationally competitive. The second industrial revolution was launched at the beginning of the 20th century and was mainly caused by the mass production of goods (e.g. by Fordism). This flow production was realized by the access to electrical energy. The merging of real (physical) objects with information processing (virtual) objects is called cyber-physical system (CPS) .These systems will offer a crosslinking of resources, information, objects and people in order to achieve efficient and high flexible manufacturing. The cross-linking results in real-time managing and optimizing the entire production system, future companies as well as the entire logistic supply networks [6, 7]
