GB new and old method standard comparison

During the wearing process of the garment, small pompons are often found on the surface of the garment, which is the so-called pilling phenomenon.The ball is a physical change to the surface of the garment. This is due to the friction between different parts of the garment, or the pilling phenomenon caused by friction with other objects, such as backpack tables. The process of this The phenomenon is usually as follows:

Due to friction, some loose fibers are separated in the fabric yarn, and these fiber ends emerging from the surface of the yarn can easily form balls with stains and impurities on the surface of the garment, and then the body of these balls gradually increases. Assuming that these balls are still attached to the fabric under the influence of external force and become larger and larger, we call this thethe pilling phenomenon. In view of this phenomenon, there are three methods of testing pilling in China, namely: circular trajectory method, Martindale method and rolling box pilling method! The pilling test of woven fabrics usually uses the circular track method and the Martindale method! The Chinese GB/T4802.2 standard is the Martindale method test, because GB/T4802 the .2-2008 standard has made major revisions in GB/T4802.2-1997. Therefore, we compared the two standards and performed comparative tests based on the conditions specified in them. This article will have some discussions about it:

1Standard comparison

GB/T4802.2-2008 standard and GB/T4802.2-1997 standard have the same testing principle, they are all round samples Installed on the Martindale tester, the surface of the sample and the surface friction trajectory of the same sample is a Lissajous figure.

2 Comparison of test results

OSince the jacquard fabric contains different varying structures, 10 jacquard fabrics with different specifications and patterns were selected as comparative examples. Since the standard GB/T4802.2-96 stipulates that the number of rubbing is 1000 times, while the standard GB/T4802.2-08 stipulates that the test end point of woven fabrics should be at least 2000 times.

3 Discussion of Test Results

According to the data in Table 2, it can be determined that the pilling results tested by the modified Martindale Abrasion Tester are 90% better than those tested by Martindale. abrasion tester tested pilling results (except sample no. 8) and the degree of influence of the number of rubs on pilling, there is little difference between the modified Martindale abrasion tester and the Martindale abrasion tester.
