Time-temperature to strength relationship of viscose cord fibres

Conclusions 1. The time-temperature to strength relationship of a representative series of viscose cord fibre specimens has been investigated.2. Change in the structural factor and also departure from linearity of the endurance curve have been established.3. The possibility of alteration in the nature of the rupture process of cord fibre, depending upon a state past second order transition or a viscoelastic state, has been demonstrated.All-Union Research Institute for Synthetic Fibres (VNIIV).

Certain reasons for the reduction in strength of viscose cord on being twisted

Conclusions We therefore conclude that the lower strength of twisted cord, as compared with the total strength of the initial threads (i.e. the strength utilisation factor), is determined to a large degree by damage and breaks in the elementary filaments as the result of twisting.All-Union Synthetic Fibre Research Institute (VNIIV).
