Pilling performance test experiment by circular trajectory method أداة الاختبار –

During the wearing process, fabrics are prone to pilling due to internal (fiber type, fabric structure, finishing, etc.) and external reasons (friction, snagging, etc.), which seriously affects the use of textile clothing. Performance and aesthetics. There are currently four methods for testing the pilling of textile clothing in China: the circular path method, the modified Martindale method, the pilling box method and the random tumbling method. The corresponding method standards are GB/T4802.1-2008, GB/T4802.2-2008, GB/T4802.3-2008 and GB/T4802.4-2009. According to the statistics of the testing agency, among these testing methods, the circular trajectory pilling method is more frequently used. The circular path pilling tester is an experimental testing instrument. Qisnun Precision Mechanical and Electrical Technology Co., Ltd. is the manufacturer. Customers in need are invited toask about. .

Pilling mechanism:

In daily life, textiles are often worn, used and washed, and continue to suffer When exposed to friction and other forces from the outside world and itself, the fiberss of the surface are gradually torn off and exposed, and many small lints appear on the surface of the textile. This process is called “fluffing” and lint cannot be removed from the surface with continued use. The surface of the textile immThe particles immediately detach and entangle with each other, forming numerous dense spherical particles. This process is called “pilling”. The circular path method test uses a nylon brush and fabric abrasive test materials or only fabric abrasive. According to the specified method and test parameters, the test sample is rubbed to cause pilling, and then, under the specified lighting conditions of the light source in the evaluation area, visual description and evaluation of the pilling state of the fabric are carried out. As the main test materials, fabric abrasives, jFoam anoints and nylon brushes have a significant impact on the quality of fabric pilling assessment.

Shanghai Fanbiao Textile Testing Technology Co., Ltd., as an enterprise integrating R&D, manufacturing, sales, training and service, is committed to putting more testing instruments in the market and long-term supply of textiles, leather, combustion, automobile interior materials, environmental climate aging testing instruments such as masks, protective clothing, etc. can also accept non-standard customization. Targeted testing can be carried out according to customer requirements before purchase to ensure that the purchased instruments are suitable.
