Definitions
- This fiber production process has considerable advantages over the prior art Technique using the meltblown process, which also produces microfibers.
- the threads are very fine, they have an average diameter of about 2 microns and even with this diameter are essentially endless. Since she is not like that Meltblown process by a hot air stream, they are stretched not thermally damaged and have a high strength.
- the threads can off made of any polymer but also from solutions according to the lyocell process become.
- Microfibers are also called split fibers. They arise from threads that are made several polymers are spun and then z. B. by Water jets are split. But this microfiber manufacturing process is consuming.
