Scope of application:It is used to test the anti-drilling properties of textiles such as linings and fabrics of various down products by the roller box method.
Applicable standards:GB/T12705.2;FTMS191A, etc.
Technical indicators:
1. Internal dimension of rotary box: 600mm × 600mm × 600mm;
2. Rotary box speed: 42r/min;
3. Setting of maximum operation times: 999999;
4. Power supply: AC 220V ± 10% 50Hz;
5. Rubber ball: 24;
6. Power: 150W.
Test principle:
The sample shall be made into a bag, filled with down of specified quality, and put in the rotary box of the tester, and at the same time, the rotary box shall also be filled with hard rubber ball. The rotary box rotates at a specified speed, bringing the rubber ball to a specified height and dropping it to impact the sample, so as to simulate various extrusion, rubbing and collision effects of down products in the taking process. The anti-drilling property of the fabric was assessed by counting the number of down roots drilled from the inside of the sample.
