31—Some Effects of Temperature on Wet Viscose Rayon

In the processing of textiles the material may be subjected to tension while at elevated temperatures in the wet state. It is therefore of practical interest to know how the tensile properties of textiles in the wet state are affected by high temperatures.Speakman and co-workers1,2,3 have studied the effect of temperature on the load-extension curves of wool and nylon and on the relaxation of stress in stretched human hair. Katz and Tobolsky4 have studied its effect on the relaxation of wool, but other fibres seem to have been neglected in this respect. In the present work, load-extension curves for completely wet viscose rayon have been measured at temperatures between O° and 100°C, and the effect of temperatures between 15°C and 100°C on the relaxation of stress with time in stretched viscose rayon immersed in water has also been studied.
