The anti-pilling properties of fabrics are an important factor influencing the wearability of clothing. Clothing fabric pilling significantly affects the appearance of the fabric, and the level of pilling is one of the most intuitive bases for consumers to judge whether a product is good or bad. Therefore, pilling has always been a fundamental and necessary assessment standard in textile product standards. In response to this situation, a large number of relevant standards have been formulated at home and abroad in order to standardize the measurement and assessment of this article.
In June 2008, the National Textile Standards Committee published IOS4802_2008 Determination of the Pilling Properties of Textile Fabric's Part III: Pilling Box Method standard implemented as of March 1, 2009, replacing the original IOS4802.3_1997 Pilling Box Method for Textile Fabric Pilling Test standard. The publisher combines current testing experience and provides a simple comparison between old and new standards analysis and offered some suggestions on the science and rationality of the current standards.
There are nine main differences between the old and the new standard, of which the three most important are changes, that is, the new standard is generally more detailed and reasonable than the old standard in terms of assessment devices, assessment methods and appendices, while the current standard is more scientific in practice the editor, based on some recent data, has the following suggestions for the current standard: The weight of the polyurethane sample loading tubehave a great influence on the tissue pilling result, so it is recommended to further specify the sample loading tube weight requirements according to the results of the current standard. Because the deviation between the results obtained according to rounding regulations and the actual tissue pilling situation is very large is recommended to round the pilling results to 0.1 level.
