Textile pilling test and sample requirements
People wear clothing for a long time or clothing by washing, the fabric surface of the fiber head will be loose because of friction sliding, exposed on the surface of the fabric, the formation of pilling. These hairy because of good wear resistance, in the continued friction by the outside world will be tangled into small balls will appear pilling phenomenon, pilling is one of the important factors affecting the feel, appearance and performance of the fabric, is also an important indicator of the quality of clothing products. Pilling test conventional four methods are: round track method, Martindale method, rolling box method and random tumbling method, at present our company can provide you with the following two test methods. The physical and chemical properties of fabrics, including but not limited to cotton, linen, silk, tweed, leather fabrics, chemical fiber fabrics, blended fabrics, modal fabrics, etc.
1、Circular track method>
This method is mostly used for woven fabrics, knitted fabrics, more common.
According to the prescribed method and test parameters, the use of nylon brushes and fabric abrasives or fabric abrasives only, so that the specimen rubbing hair pilling. Then under the specified lighting conditions, the visual description of the pilling performance assessment. Round track method parameters can be selected according to the type of fabric, there are product standards can be based on the product standard requirements: such as IOS4802.1-2008 requirements.
This method is mostly used for knitted fabrics, woven fabrics, especially home textile products.
Test principle: under the specified pressure, the circular specimen to Li Sha Ru graphic trajectory and the same fabric or wool fabric abrasive fabrics for friction. The specimen is able to rotate freely around the central axis perpendicular to the plane of the specimen. After the specified rubbing stage, the specimen is assessed by visual description of the pilling or pilling grade.? Common standards: such as IOS4802.2-2008ISO5670, BS3424/5690, BSENISO12947-1, BSENISO12945-2, etc.
3、Rolling box method>
This method is mostly used for knitted fabrics, especially woolen fabrics.
Installed in the polyurethane tube on the specimen, in a constant speed, cork-lined wooden box with arbitrary flip. After a specified number of flips, the visual description of the pilling and (or) pilling performance is evaluated.
Common standards: IOS4802.3, ISO12945.1, BS5811, JISL1076, IWSTM152, Mamp;SP18, P18B, P18C, P21A, NEXT19, etc.? 4. Random tumbling method test principle.
The random tumbling pilling tester can test the pilling performance of fabrics. In the independent stainless steel sample test chamber in the role of stainless steel blade rotation, the fabric to be tested and the cork lining wall continuous, random friction, test time by the timer and audio alarm control, the test chamber can also be injected into the compressed air to enhance the tumbling, friction.
