Preparation and properties of viscose staple fibre modified by grafting polyvinyl chloride

  • 31 Accesses

Conclusions

1. The authors have obtained modified viscose fibres containing PVC in amounts reaching 25–230% of the weight of cellulose. The molecular weight of the grafted chain varies between 40,000 and 140,000; the degree of conversion of cellulose does not exceed 13–22%.

2. It is shown that grafting of PVC increases the absolute strength and elongation of fibres, reduces the loss of wet strength, and reduces the resistance to repeated bending. A marked reduction of the fibre number reduces their strength.

3. The results are explained by the probability that graft copolymerization takes place on a supramolecular level.
