This proposal project specifies a method intended for determining the anti-contamination propensity of fabrics to particulate matter. This method is applicable to woven fabrics which may or may not have been given an anti-contamination to particulate matter finish. It is especially suitable for measuring apparel fabrics. It is not intended for use in fabrics that react to UV light or allow particulate matter to penetrate into the structure of the fabric.
This document provides a method how to determine the anti-contamination propensity of fabrics to particulate matter. This test method just evaluates the level of contamination with particulate matter adhering to textiles that are only worn in living environments.
As the concentration of particulate matter in the air has increased, many countries in the world are exposed the particulate matter. Particulate matter (PM) is solid and/or liquid particles suspended in ambient air defined in ISO 16890-1 and is one material of air pollution. This test method applied particulate matter, PM 10, to this test method. The PM10 is one of the particulate matters managed internationally, including the WHO.
Generally, particulate matter clashes with the surface of clothing, and some particulate matter may adhere to textiles. As consumers have been more interested in air quality, the textile industry also has been developing clothing products that prevent dust from attaching to the surface. However, due to the absence of a standardized test method and the properties of the textile such as the various color, types, and patterns, the companies in the textile industry have been in some difficulties proving the new technologies and evaluating the function of products.
The main principle of this test method is to measure the test particle's anti-contamination performance by exposing a certain amount of the test particle to the fabric for a period of time, measuring the ratio of the area that is not attached to the fabric surface.
It used fluorescence test particle matter that can emit green light under UV Light conditions, so that can see easily test particles on the surface of fabrics and measure the amount of test particles. The test particle is not affected by the color of the fabric because it performs under UV Light in the dark room. For quantitative evaluation, it used a digital measurement method capturing images and analyzing the amount of test particles on the surface of fabrics.
Through this test method, it is expected to provide correct information to stakeholders including the manufacturer with the objectivity of the anti-contamination propensity of the fabrics to particulate matter.
