Purpose - This paper aims to investigate the elasticity of hemp woven fabric under action of bending force, before and after washing treatment. Design/methodology/approach - Bending elasticity was monitored in three different ways: through the value of bending modulus, on the basis of fabric's resistance to creasing expressed through the value of quality number, and through the value of bending deformation components. On the basis of the results obtained from the mentioned three types of investigations, the complex criterion of quality of washed and unwashed hemp fabric, from the aspect of their elasticity, was formulated. Findings - Values of complex criterion as well as the values of bending modulus, quality number and total recurrent deformation pointed to the conclusion that investigated hemp fabric has, not good, but satisfied bending elasticity, especially after washing treatment. The values of bending deformation components served for establishing Frenkel's model of elastic beha...viour under action of bending force of washed as well as unwashed hemp fabric. Practical implications - Shows that the way on which Frenkel's model was established might be interesting because of its simplicity. Originality/value - Provides information on the elasticity of hemp woven fabric before and after washing.
