Effect of moisture on the properties of Togilen fibre

The sorption properties of Togilen fibre were determined. Desorption of Togilen is similar to desorption of viscose fibres with respect to the equilibrium moisture absorption and sorption kinetics. It was found that the curve of the strength characteristics of Togilen as a function of the humidity decreases monotonically. The maximum decrease in the strength is 50% of the conditioning value. The change in the deformation-strength properties of the fibre in water as a function of the duration of its exposure was investigated. The time of establishment of equilibrium with respect to the strength and elongation was determined. The loss of strength of the wet fibre attained 60–70% and the elongation increased by two times; the properties of the fibre were almost totally restored during drying. A comparison of the properties of textile fibres with elevated sorption properties and Togilen suggested that Togilen is a hydrophilic fibre.
