Description

Technical Field

[0001] This utility model relates to the field of wrinkle resistance testing technology for knitted fabrics, and in particular to a device for testing the wrinkle resistance of knitted fabrics. Background Technology

[0002] The wrinkle resistance of knitted fabrics, also known as fabric wrinkle elasticity, mainly depends on the elastic recovery rate of the fibers that make up the fabric, yarn twist, fabric structure, unit area mass, warp and weft density, and the processing and finishing of the fabric.

[0003] Currently, the knitted fabric wrinkle resistance testing equipment used by fabric manufacturers and testing units generally includes a lifting drive device, a weight, and a worktable. In use, the fabric sample is first folded and placed on the worktable. Then, the lifting drive device presses the weight onto the worktable covering the fabric sample with a certain pressure for a period of time. After that, the lifting drive device drives the weight to rise, and then a CCD (charge-coupled device) camera is used to take pictures and collect images of the sample directly above the folded corner of the fabric sample. The images are then processed and calculated by the knitted fabric wrinkle resistance testing instrument to obtain the test results of the fabric sample crease recovery angle.

[0004] However, traditional knitted fabric wrinkle resistance testing devices rely on manual bending of the fabric during testing. In the process of manual bending, the bending distance and degree vary for different fabric samples, which can easily lead to errors in subsequent test results. Utility Model Content
