Analysis of the detection test of the pilling tester by the circular trajectory method
The circular track method pilling testing-equipment' target='_blank'>tester uses linear guides as sliding gauges to test the pilling conditions of wool fabrics, chemical fiber pure cotton, blended, knitted and woven fabrics to identify product quality and process effects, (Hong Kong) Co., Ltd. Is the manufacturer, welcome to inquire. Test principle: Use nylon brushes and abrasives or single-use abrasives to rub and pill the fabric, and then compare the pilled samples with the standard photos under specified light conditions to evaluate the pilling grade. Main parameters: 1. The contact gap between the grinding head and the grinding table plane:≤0.2mm; 2. Parallelism of grinding head and grinding table:≤0.3mm; 3. Relative movement track of grinding head and grinding table: 40±1mm; 4. The nylon brush surface is flush, and its height difference: less than 0.5mm; 5. The reciprocating speed of the grinding table: 60±1 time/min; 6. Grinding head weight: 490cN±1%; 7. Heavy hammer weight: 290cN±1%; 8. Weight of small weight: 100cN±1%; 9. Choice of times: 1——9999. Pilling test: 1. Set the number of counters according to GB4802.1-97. 2. Take the sample and clamp it into the sample chuck correctly and firmly. 3. Lower the specimen chuck so that the specimen is in contact with the abrasive plane. 4. Press“RUN”key to make the instrument do the pilling work. 5. After the automatic shutdown, turn up the sample chuck, and take off the test sample for evaluation. Fluff test: 1. Take the sample and clamp it into the sample chuck correctly and firmly. Set the friction times for the counter according to GB/T4802.1-97. 2. Select the sample weight according to the regulations. If you need to increase the weight, you can tighten the required weight on the chuck shaft. 3. Put down the specimen chuck so that the specimen is in contact with the brush plane. 4. Press“RUN”key, the instrument can be rotated according to the set number of times, and the instrument can automatically stop when the set number is reached.
