Moisture resistant microbial penetration tester

Non woven fabric dry state falling floc tester

The non-woven dry state fluff tester is also known as twist tester. It is used to evaluate the fluffing test of nonwovens under dry conditions. It is mainly applicable to the evaluation of the shedding performance of non-woven fabrics and other textile materials used for medical protective materials (operation sheet, operating clothes, clean clothes, etc.). Test principle: the sample is subjected to a combined action of torsion and compression in the test chamber. During the twisting process, air is extracted from the test chamber, and the test results are evaluated by counting and classifying the particles in the air with a laser dust particle counter

Product parameters:

1. Sealed torsion chamber and air conditioner

2. Twist speed: 60 times / min

4. Sample fixture: 82.8mm

5. Laser particle counter test range: 0.3-25.0um samples were collected

6. Laser particle counter flow rate: 28.3l/min, ± 5%

7. Sample test data storage: 3000

8. Timer: 1-9999 times

Principle:

The sample of non-woven fabric dry floc tester is subjected to a combined action of torsion and compression in the test chamber. During the twisting process, air is extracted from the test chamber, and the particles in the air are counted and classified by laser dust particle counter.
