Spinning process information for DW7091A

Author:QINSUN Released in:2023-06 Click:35

DW7091A is a research device designed for research into new spinning processes. Its function consists of precise temperature control, precise dosage, water bath, stretching and winding. All of these parameters can be adjusted to suit your research needs.

And DW7091A is different from other instruments, such as B. strength testers. A strength tester has fixed standards, you can set parameters according to each standard to get the corresponding results, but for DW7091A, even the same material There can be many kinds of technological processes, and different technological processes lead to different results. Even if you get one spinning process, another must work well. Therefore, there are still many problems during your own spinning process, because there are so many details, such as material ratio, dissolved material state, coagulation bath concentration and temperature, stretching speed, etc. Each parameter can become one lead to spinning errors. The process depends entirely on your own research and experience.


Please be patient while researching and think carefully about the reasons for the failure. We believe that you can succeed after summing up the experience.

Also, every time you finish the test, please do thorough cleaning, especially the spinneret component (see picture below). After each spin, the spinneret component should be removed and cleaned. The filter in the The spinneret component must be before the näcmust be replaced with a new one, otherwise it will block. We have fitted some replacement filters with the machine.

And if your material is not well dissolved, it will also clog in the filter. For example, for polyvinyl alcohol powder, the concentration is 12%. The fully dissolved solution is transparent and viscous. If you choose to edit it with something, you won't see any particles or lines (see image below).
