Introduction
For NIPS membranes and TIPS membranes prepared from homogeneous materials, the membrane strength is entirely provided by the separation membrane material itself. In order to enhance the mechanical strength of the hollow fiber membrane, one or two layers of a casting liquid can be coated onto the outer layer of the braided tube, with the polymer film formed and bonded to the braided tube through a solution phase transformation process. We offer braided tube coated follow fiber film spinnerets that meet all of your requirements for coating one or two layers of the casting liquid on the outer layer of the tube.

Suitable materials
PVDF (Polyvinylidene Fluoride), CA (Cellulose Acetate), PVC (Polyvinyl Chloride), PES (Polyethersulfone), PSF/PSU (Polysulfone), PA (Nylon, Polyamide), PAN (Polyacrylonitrile)

We can provide a removable spinneret design that differs from traditional spinnerets. In a traditional spinneret, each hole cannot be independently replaced or disassembled. If a problem arises in one, the spinneret in its entirety needs to be repaired or scrapped. Our spinnerets are designed so that each hole can be individually replaced, without the hassle of fixing the entire machine.
