Description

Technical Field

[0002] Soft elastic fabric is a kind of fabric with good elasticity and softness, usually woven from a mixture of elastic fibers and non-elastic fibers. This kind of fabric is widely used in clothing, sports equipment, medical supplies and other fields because of its comfort and adaptability to body movement. With the improvement of environmental awareness, more and more attention is paid to the use of environmentally friendly materials and processes in the production process of soft elastic fabric. The production of soft elastic fabric is a complex process involving material selection, process design, quality control and other aspects. With the development of science and technology, new elastic fibers and weaving technologies continue to emerge, providing more possibilities for the development and application of soft elastic fabrics.

The utility model has a simple structure and low production cost. After finishing, the elasticity of the fabric meets the requirements, and it can improve work efficiency and ensure product quality, which is suitable for industrial production.

[0004] However, in the production process of fabrics, different types of fabric materials may have different elastic properties. Since the elasticity and deformation ability of fabrics have a great influence on the quality and appearance of the product, it is necessary to detect the deformation and rebound ability of different types of fabrics under force. In the existing detection process, most of them adopt the method of clamping the fabric and observing the deformation of the fabric by the operator manually applying pressure. However, long-term manual operation may cause fatigue of the operator, and the stability of the hand is difficult to ensure. Different operators may have different problems such as different force sizes and directions, which further affects the accuracy of the test results.
