Fabric pilling, the formation of small balls or pills on the surface of a textile material, is a common problem that affects the appearance and quality of fabrics. ISO 12947-2:2010 is an international standard that provides a method for determining the resistance of fabrics to pilling. In this article, we will explore the key aspects of this standard and its significance in evaluating fabric performance.
Standard Scope and Objectives
ISO 12947-2:2010 is part of a series of standards developed by the International Organization for Standardization (ISO) to assess the performance of textiles. This specific standard focuses on the determination of fabric pilling resistance using the Martindale abrasion tester. The objective is to provide a consistent and reliable method for assessing the quality and durability of fabrics under simulated wearing conditions.
Test Procedure and Equipment
The ISO 12947-2:2010 standard outlines a detailed procedure for conducting the fabric pilling resistance test. The test involves subjecting the fabric sample to a specified number of rubbing cycles using an abrasive rubbing material. The Martindale abrasion tester is commonly used for this purpose, as it can accurately replicate the wear-down process observed in real-life usage scenarios.
During the test, the fabric sample is stretched taut over a specimen holder and rubbed against the abrasive surface in a back-and-forth motion. The number of rubbing cycles varies depending on the fabric type and intended application. After the test, the sample is evaluated for the formation of pills, and the severity of pilling is assessed based on standard rating scales.
Significance and Interpretation of Results
The results obtained from the ISO 12947-2:2010 test can provide valuable insights into the performance of fabrics in terms of pilling resistance. A lower pilling rating indicates better fabric quality and durability, as it signifies a reduced tendency to develop surface pills. Manufacturers, retailers, and consumers can use these ratings to make informed decisions about fabric selection, ensuring that the chosen material meets their specific requirements.
It is important to note that the ISO 12947-2:2010 standard does not dictate specific acceptance criteria for fabric pilling resistance. Instead, it serves as a benchmarking tool, allowing fabric producers to compare their products against established industry standards and customer expectations. By complying with this standard, manufacturers can demonstrate the quality and reliability of their fabrics, giving end-users confidence in their purchasing decisions.
