Effectively sealing textile fluid bags
This efficient sealing method for multi-layer, woven, three-dimensional fluid containers enables a wide range of applications in a wide variety of industries.
The sealing process can also be integrated into existing manufacturing processes and is suitable for gases and liquids.
Composite materials with integrated hinge zones – bio-inspired lightweight actuators for panel elements
This bio-inspired lightweight technology makes it possible for the first time to integrate actuators in surface elements made of composite materials and thus open up completely new design possibilities - not only for architecture.
Variable number of threads in braiding machines
A new embodiment of a braiding machine was developed at the Institute of Aircraft Design (IFB) of Stuttgart University. It features a thread positioning unit which forms a secondary ring of horn-gears close to the braiding point. This secondary ring moves synchronously with the primary horn-gears of the braiding machine. Therefore, the position of each thread, that is close to the mandrel, is clearly defined. This is a basic requirement for manipulation of specific threads during the braiding process, which in turn permits the automated production of components with highly varying diameters at a constant braid angle.
Cellulose-based micro- and super-microfibres produced as continuous yarn suitable for weaving and knitting
A novel direct-wet-spin process was developed and patented by the German Institute of Textile Chemistry and Chemical Fibres (ITCF) in Denkendorf, which allows for the first time the cost-efficient production of micro- and supermicro-fibres of less than 0.1-0.5 dtex (fibre surface about 1 - 4 m2/g) from cellulose and cellulose-2.5-acetate in the form of a continuous fibre in a single-step process. The fibres can be stored as staple fibres or wound up as a continuous fibre for further processing.
