Permanently crimped acrylic fibres

Two different fibre components A and B are produced by copolymerisation of 3 or 4 acrylic monomers, or of 2 or 3 acrylics and one allyl monomer. Each copolymers is dissolved in an inorganic solvent. The two-component fibre is produced conjugately by extracting A and B in a bath containing an inorgan...

Beschreibung
Zusammenfassung:	Two different fibre components A and B are produced by copolymerisation of 3 or 4 acrylic monomers, or of 2 or 3 acrylics and one allyl monomer. Each copolymers is dissolved in an inorganic solvent. The two-component fibre is produced conjugately by extracting A and B in a bath containing an inorganic acid. The fibre is then washed, stretched, oiled, dried and subsequently passed through hot water at constant speed and in a relaxed state.
