Fibre Preparation & Yarn Production
The focus of yarn development is material testing of natural fibers of predominantly plant origin. One full-stage short stack line for tape, yarn and twisted thread production is available for this purpose. Fiber quality is determined and evaluated in original state as well as according to individual process stages.
Functionalized special fiber variants as well as fibers from various recycling processes are examined with regard to their suitability for staple fiber spinning process.
For optimal use of property potentials of reinforcement fibers, main focus lies on structures oriented for fiber composite construction. For this purpose, carded strand and tape structures are developed as textile semi-finished products.

Oriented strand-like structures from recycled carbon fibres
Based on the research results of the STFI regarding the reuse of recycled carbon fibres in different nonwoven structures, further investigations were carried out on better fibre orientation in MD direction:
- Development and production of slivers
- Subsequent inline consolidation to form secondary rovings
- Development and production of doubled and stretched staple fibre webs
- Subsequent thermal bonding to form tape structures
