ISO 105 X12 Color Fastness to Rubbing Testing for Export Garments
The ISO 105 X12 test is a critical method used in textile and apparel export testing. This standard evaluates the resistance of dyed or printed textiles to color transfer during rubbing against another fabric, skin, or similar surfaces. The primary purpose of this test is to ensure that garments meet international standards for colorfastness, which are essential for maintaining brand integrity and ensuring customer satisfaction.
The ISO 105 X12 method simulates the frictional contact between fabrics in use, such as rubbing against skin during wear or rubbing against another fabric. This ensures that colors do not bleed or transfer to other materials, thereby preventing quality issues and potential complaints from customers abroad. The test is particularly important for garments destined for export because it helps ensure compliance with the importing country's regulations.
The testing process involves several steps. First, a sample of the garment is prepared according to ISO 105 X12 specifications. This typically means cutting out small pieces of fabric that will be used for the test. The sample is then rubbed against a standard rubbing cloth using a specified rubbing machine with defined pressure and time parameters.
The rubbing machine applies controlled friction, simulating real-world conditions such as rubbing or handling by the end user. The color transfer onto the rubbing cloth is closely monitored at specific intervals to determine when color migration becomes significant enough to be considered a failure of the test. It's important to note that this method does not assess the durability of the fabric itself but rather focuses on the integrity and stability of the dye or printing.
The acceptance criteria for ISO 105 X12 are based on visual inspection, where the amount of color transfer is compared against predefined thresholds. The test results can be reported as either pass/fail or with a quantification of the color change using a standard scale such as灰色输出
