Products Description
The multi-layer wet spinning machine is a sophisticated apparatus used in the chemical fiber industry for producing fibers through a solution-based spinning process. In this method, a polymer is dissolved in a suitable solvent to form a spinnable solution. This solution is then extruded through the fine orifices of a spinneret, creating thin streams of the polymer solution. These streams are subsequently introduced into a coagulation bath, where the solvent diffuses out and the polymer solidifies, forming continuous fibers.
This wet spinning technique is particularly suitable for fiber-forming polymers that exhibit certain characteristics. Specifically, these polymers either have a decomposition temperature lower than their melting point or are prone to discoloration when exposed to heat. Additionally, they must be soluble in an appropriate solvent to facilitate the spinning process.
The versatility of wet spinning is demonstrated by its ability to produce various types of fibers. It is commonly employed in the manufacture of synthetic fibers such as polyacrylonitrile fibers and polyethylene (PE) fibers. Furthermore, it is extensively used for producing man-made fibers including viscose fibers and cuprammonium (cupro) fibers. This method’s adaptability to different polymer systems makes it a crucial technique in the textile and fiber production industries.
Scope of application: It is suitable for verifying the possibility of wet spinning of materials and exploring the performance parameters of material spinning.
Applicable materials: polyacrylonitrile, polyvinyl alcohol, rubber, chitin, vinylon, aramid, acrylic, polyvinyl chloride, ordinary viscose.
