Problems solved by technology

If the fabric is stretched for a long time, its creep and relaxation will be large, which will deform the embroidery pattern and affect the quality of the finished embroidery
However, there is currently no effective test method for determining the creep and relaxation properties of fabrics, and the selection of qualified embroidery base fabrics only depends on the experience of the operator, which lacks reliability and operability
Especially when formulating embroidery-related product standards, this performance indicator cannot be determined for embroidery base fabrics

Abstract

The invention discloses a fabric creep and relaxation testing method and a special device thereof. A tested fabric can be subjected to long-duration and constant stretching, a heavy punch hanging method is adopted in the process of testing the fabric creep, and creep elongation of the fabric is measured. When relaxation of the fabric is tested, one end of a fabric sample is fixed, constant tension is applied to the fabric by using a lifting screw at the other end, the center of the fabric is tensioned by using a tensioning rack, and a force measuring device is suspended on the tensioning rack and is used for measuring relaxation change of the fabric. The method is suitable for creep and relaxation test of embroidery blank fabrics.

Description

technical field [0001] The invention relates to a method for testing physical properties of textiles and a special testing device thereof. technical background [0002] General textiles, including fibers, yarns and fabrics, will produce a certain amount of elongation deformation under the action of a constant tensile force. After the stretching force is applied to the textile, the stretching deformation immediately produced by the textile will immediately produce a retraction deformation after the stretching force is removed, and this deformation is called acute elastic deformation. Under the action of a constant tensile force, the deformation that changes with the continuation of time, and the retraction that changes with the continuation of time after the tensile force is removed, are called slow elastic deformation. Textiles also undergo a certain amount of plastic deformation under tensile force, which also increases with time and cannot recover when the tensile force i...
