Synthetic fiber made by spinning polyvinyl alcohol as raw material. The polyvinyl formal fiber obtained by treating this fiber with formaldehyde is called vinylon in China and vinylon in the world. The fibers obtained by spinning relatively low molecular weight polyvinyl alcohol as raw materials are......
