Abstract: Epoxy resin-based fibre matrix compositions contain alkyl substituted ethylene amines such as dimethyldiethylenetriamine (DMDETA, also dimethyl-1,4,7-triazaheptane), as a curing agent. These curing agents are characterized by a short curing time for a comparatively long processing time, and make it possible to obtain cured epoxy resins that exhibit low brittleness and high tensile strength and have a high glass transition temperature; as a result of which the fibre matrix composition is suitable particularly for use in pultrusion and winding processes.

Abstract: A process produces a thermoplastic polyurethane (TPU) fiber with low shrinkage, in particular at a high spinning speed. The resulting fiber can be used for fabric, especially for garments and shoes. The process combines the high-speed spinning process with the heat-setting process. This allows the process to produce a TPU fiber in high productivity, which could greatly decrease the cost. Moreover, the obtained TPU fiber has very low shrinkage of <10%, which makes it well suitable as the main raw material in fabrics.
