Detection of tensile elastic recovery rate of knitted fabrics

The tensile elastic recovery rate of knitted fabrics refers to the deformation that the material can recover after removing external force after being stretched to a specified length. It is expressed by the tensile elastic recovery rate. Knitted fabrics with strong stretch elasticity recovery rate can freely expand and contract with the activities of the human body, eliminating or reducing the tension and pressure on the body, without causing a tight feeling and making people feel comfortable.
Zhongke Testing Environmental Reliability Experiment Center has the ability to test the reliability performance of various textile raw materials and products, and provides professional tensile elastic recovery rate testing services for knitted fabrics.

Use special instruments and equipment to stretch the sample to deform its length. After the tension is released, the elastic deformation and plastic deformation are calculated based on the deformation size.
