Embodiment 1

[0022] Sample fabric parameters: raw material 100% cotton, plain weave, warp yarn density 41.6tex, weft yarn density 58.3tex, warp density 350, weft density 280.

[0023] The steps of testing the sample fabric with the fabric wrinkle recovery performance device of the present invention are as follows:

[0024] Step 1: Select the fabric to be tested with a size of 380mm×380mm, and place the fabric to be tested horizontally on the sample table 4;

[0025] Step 2: Start the lifter 12, lift the fabric to be tested by 80mm at a rising speed of 0.02m / s through the sheet 11, so that part of the fabric to be tested enters between the left press block 9 and the right press block 10, and passes through the left cylinder 7 And the right cylinder 8 makes the left pressing block 9 and the right pressing block 10 move toward each other at a speed of 0.02m / s, and after contacting the fabric to be tested, apply a pressure of 20N, pressurize for 1min, and then control the left pressing block 9...

Embodiment 2

[0028] Sample fabric parameters: raw material 65% cotton / 35% polyester, two up and one down left twill weave, warp yarn density 58.3tex, weft yarn density 58.3tex, warp density 320, weft density 250.

[0029] The steps of testing the sample fabric with the fabric wrinkle recovery performance device of the present invention are as follows:

[0030] Step 1: Select the fabric to be tested with a size of 380mm×380mm, and place the fabric to be tested horizontally on the sample table 4;

[0031] Step 2: Start the lifter 12, lift the fabric to be tested by 80mm at a rising speed of 0.02m / s through the sheet 11, so that part of the fabric to be tested enters between the left press block 9 and the right press block 10, and passes through the left cylinder 7 And the right cylinder 8 makes the left pressing block 9 and the right pressing block 10 move toward each other at a speed of 0.02m / s, and after contacting the fabric to be tested, apply a pressure of 20N, pressurize for 1min, and ...

Embodiment 3

[0034] Sample fabric parameters: raw material 100% wool, two upper and two lower left twill weaves, warp yarn density 16.6tex, weft yarn density 14.6tex, warp density 345, weft density 300.

[0035] The steps of testing the sample fabric with the fabric wrinkle recovery performance device of the present invention are as follows:

[0036] Step 1: Select the fabric to be tested with a size of 380mm×380mm, and place the fabric to be tested horizontally on the sample table 4;

[0037]Step 2: Start the lifter 12, lift the fabric to be tested by 90mm at a rising speed of 0.02m / s through the sheet 11, so that part of the fabric to be tested enters between the left press block 9 and the right press block 10, and passes through the left cylinder 7 And the right cylinder 8 makes the left pressing block 9 and the right pressing block 10 move towards each other at a speed of 0.02m / s, and after contacting the fabric to be tested, apply a pressure of 25N, pressurize for 1min, and then contr...

Abstract

The invention relates to a fabric wrinkle recoverability testing device and application thereof. The device comprises a device tank; the device tank is sequentially provided with a console, a camera and a fabric clamping device from front to back; the console controls running of the camera and the fabric clamping device and comprises control buttons and a display screen; the fabric clamping devicecomprises a sample table, a left cylinder, a right cylinder, a left pressure block, a right pressure block and a thin sheet; the thin sheet is arranged at the middle part and is parallel to the leftside surface; the upper end of the thin sheet is flush with the upper plane, and the lower end is connected with a lifter; the lifter controls the thin sheet to penetrate through the upper plane to perform up-and-down vertical movement; the left cylinder and the right cylinder are symmetrically arranged on the left side and the right side of the thin sheet; the left pressure block and the right pressure block are fixedly arranged on the inner sides of the left cylinder and the right cylinder symmetrically and are parallel to the thin sheet; the left cylinder and the right cylinder control theleft pressure block and the right pressure block to perform left-and-right parallel movement respectively; and the camera is arranged at the middle part of the device tank and is perpendicular to thethin sheet, and a lens of the camera faces the thin sheet. The device has the advantages of high testing stability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of fabric performance testing, in particular to a fabric wrinkle recovery performance testing device and its application. Background technique [0002] The crease recovery performance of fabrics is an important index to evaluate the shape retention of fabrics, and the excellent crease recovery performance directly affects the wearing performance and aesthetics of fabrics. The existing fabric wrinkle recovery test method requires a lot of manual operations, such as transferring the pressed sample to the test bench, and continuously rotating the test disc to keep one side of the sample in a vertical state; the size of the sample in the existing method is small , the effective folding length is only 15mm, resulting in large dispersion of experimental results and poor test stability; the test needs to be pressurized for 5 minutes, and then released for 5 minutes to obtain the data of a sample. According to the n...
