Test Method |
According to the Germany Standard DIN53840 |
|
Application range |
A special designed instrument dedicated to analyzing the shrinkage feature test of the processed silk. The test sample creel is engraved with measurement line and the shrinkage frame, rack, stand, shelf. |
|
Scale resolution |
The scale of the silk frame is from 0-650mm. It can test five sets of test sample silk simultaneously. The minimum readable scale is 0.5mm. |
|
Test accessories |
The accessories needed are Winder and Heating Cabinet. The Maximum temperature could read 200℃. |

| l |
The whole structure is with solid design. It uses stainless and aluminum alloy material, so it is durable and stable. |
| l |
Can add pre-tension device upon request to increase the accuracy of the denier tests. |
| l |
With a counter, which can pre set fixed length rewinding, it is easy to use and operate. |
| l |
The wind speed is adjustable so as to be able to apply in various silk samples’ winding. |
| l |
The rolling speeds of the start and the stop are with auto slow-down design |
| l |
The positions of the start and the stop are with “positioning” function design. So as to benefit the on site personnel operation and sampling precision. |
