In life, textile material Western-style clothes, outdoor sports textile (such as sleeping bag, tent) and the industry of sheet are spun
Fabric (such as the airbag flaky material of receiving atmospheric pressure or various transmission belts), sheet more demanding to the practical value of its fabric
Material crease recovery coefficient directly reflects its fabric practicability performance；In industrial goods, such as metallic spring, organic matter is thin
Film etc. is more demanding to the crease resistant finishing of its material, and therefore, research flaky material crease recovery coefficient has biggish existing
Sincere justice.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of flaky material crease recovery coefficient testing device and measurement sides
Method, a kind of flaky material crease recovery coefficient testing device specific technical solution are as follows:

For sample material between the clamping device (4) and the pressure sensor (3), clamping device (4) clamping is described again
Sample material one end, the sample material other end abut against on the pressure sensor (3)；
Moved end (1) is to drive sample material to move with constant speed to static side (5).
A kind of flaky material crease recovery coefficient testing method is specific as follows:
A kind of measurement method of flaky material crease recovery coefficient testing device, it is characterised in that: following steps are used,
Step 1: choosing the flaky material having a size of C, flaky material is arranged smooth；
Step 2: flaky material both ends are clamped in moved end and the static side of push-press type tension pressurizing device respectively；

Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
A kind of flaky material crease recovery coefficient testing device as shown in Figure 1:, including push-press type tension pressurizing device, pressure
Force snesor 3, the push-press type tension pressurizing device are divided into moved end 1 and static side 5, push-press type tension pressurizing device using horizontal plus
Pressure；
Pressure sensor 3 be put in static side 5, convenient for reacting the variation of flaky material screen resilience in pressure process at any time,
The sensitivity of pressure sensor will be according to flaky material to correct.
Clamping device 4 is installed on moved end 1, sample material is between clamping device 4 and pressure sensor 3, clamping
Sample material one end, the sample material other end abut against on pressure sensor 3 clamping of device 4 again；
Moved end 1 is to drive sample material to move with constant speed to static side 5.
A kind of test of flaky material crease recovery coefficient the following steps are included:
By flaky material to be measured arrange it is smooth after, be cut into the size of defined for warp, broadwise respectively.This example
The size of middle sample is through to a length of 5cm, a length of 2cm of broadwise.
Sample both ends are held on moved end and the static side of push-press type tension pressurizing device respectively, and it is in place to adjust flaky material institute
It sets.
It is pressurizeed to the movement of static side to fabric by push-press type tension pressurizing device moved end, when moved end is at a distance from static side
When reaching pre-determined distance, stops pressurization, screen resilience corresponding to pre-determined distance is measured by mechanics sensor；
The size for adjusting pre-determined distance, measures the screen resilience of multiple groups flaky material, by the size of the screen resilience measured and in advance
If screen resilience is made in distance -- range image simultaneously carries out data analysis, as shown in Figure 2.
