We provide sol gel sintering hollow fiber membrane spinnerets with a concentricity of 0.0003mm. The sol-gel sintering method is the main preparation method for the production of PTFE hollow fiber membrane. The only drawback is its requirements for high temperature sintering in order to remove the spinning carrier and obtain a microporous structure, so there is some degree of energy and time consumption and a low membrane porosity.
Trustech is a leading polymer fiber spinning spinneret manufacturer, by combined with advanced technology of fiber spinning process and equipment from Germany we can fabricate high quality spinneret, we can offer spinnerets used wet spinning, dry spinning, melt spinning for different fiber spinning process users, we have had clients who used our spinnerets to produce hollow fiber membrane for different filtration applications.
