Experiment of testing pilling performance by circular track method

Author:QINSUN Released in:2023-08 Click:76

Due to its internal (fiber type, fabric structure, workmanship, etc.) and external (friction, snagging, etc.) reasons, the fabric is prone to pilling, which seriously affects the wearing of textile clothing . performance and aesthetics. There are currently four test methods for pilling textiles and garments in my country: the circular track method, the modified Martindale method, the pilling box method and the random tumbling method. The corresponding method standards are GB/T4802.1-2008, GB/T4802. T4802.2-2008, GB/T4802.3-2008 and GB/T4802.4-2009. According to statistics from the testing agency, the circular pilling method is most frequently used among these testing methods. Circular lane pilling tester is a testing instrument, and Qisnun Precision Electromechanical Technology Co., Ltd. is the manufacturer. Welcome customers who need to inquire.

Main parameters:

1. The contact gap between the grinding head and the grinding table: ≤0.2mm;

2. The parallelism between the grinding head and the grinding table: ≤ 0.3mm;

3. The relative trajectory of the grinding head and the grinding table: 40±1mm;

4. The brush nylon the surface is even and its height difference: less than 0.5mm;

5. The reciprocating speed of the grinding table: 60±1 times/min;

6. The weight of grinding head: 490cN±1%;

7. The weight of heavy hammer: 290cN±1%;

8. The weight of the small weight: 100cN ±1%;

9. Choice of times: 1——9999.

Pilling Mechanism:

In everyday life, textiles are often worn, used and washed, and they are continually subjected to Due to friction and other forces from the outside world and from itself, the fibers on the surface are gradually torn and protruded, and there are nomany small fluff on the surface of the textile. This process is called “fluffing”. The surface of the textile is then peeled off and entangled with each other to form many dense spherical ps of the articles. This process is called \"pilling\". The circular track test uses either a nylon brush and a cloth abrasive test material, or only a cloth abrasive. According to the specified test method and parameters, the test sample is rubbed to induce pilling, then the pilling of the fabric is visually described and graded under the light source irradiation conditions specified in the evaluation box. As the primary test materials, fabric abrasives, foam pads, and nylon brushes have a major impact on fabric pilling assessment.

As an enterprise integrating R&D, manufacturing, sales, training and service, Shanghai Fanbiao Textile Testing Technology Co., Ltd. is committed to providing more test instruments to the market, long-term supply of textile, leather, Combustion, automotive interior materials, environmental weathering Non-standard customization is acceptable, and targeted testing can be carried out according to requirements of the customer before purchase to ensure that the instruments purchased are suitable.
