What problems should be paid attention to in the random pilling test of textiles?

The textile pilling test is used to detect the pilling properties of textiles. Generally, there are different standards for textile pilling testing experiments and there are many different physical testing methods. This article is based on Standards Group (Hong Kong) Co., Ltd. The company\'s engineers will focus on introducing experimental instrument parameters and experimental precautions for random rocking pilling test.

1. Meets standards:
ASTM D3512, GB/T 4802.4, ISO 12945.3, JIS L1076-D

2. Scope of application:
Used to detect pilling properties of fabrics. The test sample and the gray short cotton were randomly rubbed against the cork liner in the pill box under the rotating and tumbling action of the pill box impeller. When the instrument generates an alarm reminder at the specified test time, the test ends.

3. Product Details:
1. Technical parameters:
(1) Sample testing chambers: 4
(2) Each test chamber is equipped with stainless steel rotating blades
(3) The testing chamber should be well sealed
(4) Equipped with a digital electronic counter
(5) Equipped with an alarm device for the end of the test
(6) Equipped with a pressure gauge and a timer
(7) Drum specifications: 146*152 mm
(8) Cork liner specifications: 452*146*1.5 mm (L*W*H)
(9) Cork rod specifications: 452*146*1.5 mm (L*W*H) agitation: L=121 mm
(10) Rotation speed: 1200r/min
(11) Compressed air: 0.014-0.021MPa
2. Instrument configuration:
(1) Standard control board
(2) Cork liner: 50 sheets/pack
(3) Gray cotton tape: 9 meters
(4) Compressor silencer (optional)
br>(5) Other *accessories recommended by the manufacturer

Four, Precautions:
(1) Pay attention to thecleaning the test room (test chamber) before and after the test.
(2) Specimens of the same sample should be tested in different test chambers.
(3) The air pressure of each test chamber should reach 14-21 KPa, and the test chamber should have good airtightness.
(4) During operation, the test chamber should be inspected frequently. If the test is wrapped around the impeller and does not turn over, or is stuck at the bottom or side of the silo, it will remain stationary. Close the air valve, turn off the air flow, stop the test and remove the sample. Record unexpected stops or other abnormal conditions of the test
(5) When the sample is stuck by the wheel, stop the test, remove the sample and clean the wheel with cleaning fluid or water . Once dry, continue testing.
(6) Use a standard laboratory tissue (tissue used to calibrate whether the pillbox or plastic linercork is contaminated) to facilitate the test.
