Spinning of hollow and matrix fibres from polysulfone melt

The possibility of fabrication was demonstrated and the basic technological parameters for spinning polysulfone fibres by the high-production melt method were determined. The polysulfone fibres developed were used as matrix and hybrid structures; thermostable composites with elevated physicomechanical properties were fabricated from such semifinished products.V. V. Gorlov participated in fabrication of the hollow fibres.Translated from Khimicheskie Volokna, No. 6, pp. 29–31, November–December, 1994.
