On the Effect of a Gas Discharge on the Properties of Jute

Abstract

The article considers the influence of high-frequency capacitive discharge on the mechanical proper-ties of jute fibres and jute fabrics. The surface changes of jute fibres were studied by scanning electron atomic force microscopy. The authors noted that after exposure to a gas discharge on the fibres, there is a smoothing of the relief boundaries, and the products of etching of the fibre surface are also visible; when etching in the air, destructed areas appear, the surface is damaged and becomes inhomogeneous. An increase in the strength of jute fibres during modification in reactive and inert gases was revealed. During the experiments, it was found that the strength of the samples of jute fibres treated in the high-frequency capacitive discharge in the argon and nitrogen medium is higher than the original fibre samples by an average of 23 %. According to experimental data, an increase in the breaking load of jute fabrics was found to be up to 20% on average. The use of plasma modification at the stage of preparation of jute fibres for carding processes is recommended.
