Challenge

The textile industry is constantly evolving and increasing its production rates in order to attend the demands of an increasingly competitive world-wide market. The fibers evolution and the increase of production speeds leads to a higher demand on wear components, especially in the yarn guides, which are present in various textile production machines. In addition of the wear problems, the yarn production faces another issue arising from the build up of static electricity in the components, which causes the accumulation of oligomers. These problems arising from the parts used currently in the industry have a major impact on productivity and processing costs, as they lead to a drastic decrease in machine performance as well as increased maintenance and production costs, for example due to cleaning and ambient filtering due to the release of oligomers.

Solution

The solution to this problem is the development of new yarn guides for the textile industry and their manufacturing process based on nanocomposite ceramic material and nanocomposite thin coatings. This innovation will be applied to case studies in order to solve the problems associated with wear and static electricity, and other friction related problems. To obtain the new technical ceramic, the whole process of ceramic injection molding (CIM) will be developed because of the components geometrical and functional specifications. The work plan contemplates the development of new ceramic matrix nanocomposite materials, the use of medium pressure injection molding (MPIM) as manufacturing process and the development of thin-film coatings by sputtering as a possibility to increase the surface properties of the components. Prototype parts will be produced according to the detected applications, following the developed production protocol, and the respective validation tests will be performed in an industrial environment.
