Embodiment Construction
[0030] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solution and the drawings.
[0031] An evaluation method of fabric shape retention, the steps are as follows:
[0032] Step 1: In the control interface system 1, set the pressure to generate the crease, the pressure time, and the interval time between the sample lifting device 5 rising to the highest point and the start of the pressure. The sample is placed on the sample table, the center line It is flush with the center seam of the sample table 3, and the parts on both sides of the sample longer than the sample table hang in the device.
[0033] Step 2: Start the experiment. The sample lifting device 5 lifts the center line of the sample so that the sample part enters the crease generation area 4. After the interval time is reached, the left and right pressure mechanisms of the crease generation area 4 move to the middle, The sample is pressurized. After the ...

The invention belongs to the field of performance detection of a textile, and particularly relates to a method for evaluating shape preservation of a fabric. The evaluation method adopts a fabric crease automatic generation and crease expansion device for testing the shape preservation of the fabric, and the fabric crease automatic generation and crease expansion device comprises an operation control interface system, a camera, a test sample table, a crease generation region and a test sample lifting device. The test sample table consists of both left and right pressure blocks; a section of each pressure block is of a right trapezoid shape; a corner of an upper edge of each pressure block is of an arc shape and is in contact with a test sample; two pressure blocks are horizontally arrangedon the surface of a fixed bottom plate above the operation control interface system; the test sample lifting device is arranged at one end of an axis gap formed by two pressure blocks, and the camerais fixedly arranged at the other end of the axis gap; the test sample lifting device moves up and down; and the test sample lifting device enables a central line of the test sample to be aligned withthe axis gap of the test sample table. The invention can provide a method for effectively and comprehensively evaluating the shape preservation of the fabric. A test result is closer to an actual usecondition. Accurate evaluation on objective representation of the shape preservation of the fabric and physical performance of the fabric is implemented.
Description
Technical field [0001] The invention belongs to the field of textile performance testing, and specifically relates to an evaluation method for fabric shape retention. Background technique [0002] With the development of the times, textiles for people are not only products for basic purposes such as clothing, decoration, and industrial use, but are also endowed with beautiful and multifunctional characteristics. The property of fabrics to maintain appearance during use is called shape retention. The shape retention of fabrics is closely related to performance and easy maintenance. The wrinkle resistance directly affects the flatness and appearance of the fabric, which is important for shape retention. index. Wrinkle refers to the irreversible deformation of the fabric under the action of external force in daily use. The wrinkle recovery performance of the fabric directly affects the shape retention and service life of the fabric. It is one of the most important properties to eva...
