Test method for pilling abrasion of fabrics
Measurement methods: 1. Pilling box 2. Random tumbling pilling test 3. Wear testing machine for pilling test 1. Pilling box: sample (125 mm×125mm) is cut from the fabric (2 for warp and 2 for weft). Sew face to face and turn around. The fabric tube is mounted on the rubber tube. Stick the loose tape with PVC tape. All four samples are then placed together in a cork-lined box of 9“×9”×9“×”, and allow the required revolution cycle. Specimens were removed and removed from the rubber tube and assessed. At the same time, the main reason for pilling is that the fibers have a high“Lateral strength”or“bending”or“low brittleness”. high“Lateral strength”May be advantageous in some applications such as technical textiles, floor coverings etc. However, the pilling trend has also increased, so in the apparel industry“low lateral strength”is desirable, especially in knitted products. Polyester fibers are intentionally brittle for use in knitted products to avoid pilling (anti-pilling type). Pellets do not form low transverse strength fibers (wool and pill-resistant rayon). They can be easily wiped off. But fiber with the power of the high side”There will be higher pilling. Anti-pilling performance and durability are negatively correlated. Pilling Grade: Grade 5 No or very weak pills. Grade 4 weak pills. Grade 3 moderate pellets. Class 2 distinct pellets. Level 1 drug strength. 2. Random tumbling pilling test: random tumbling motion of tumbling in a cylindrical test box made of light abrasive materials. For a tablet similar to actual wear, add a small amount of cotton fibers. Three specimens 105mm x 105mm with chamfered 45° lengths and edges sealed with rubber adhesive. All of these samples were dropped into the test chamber along with the cotton. The fabric samples are evaluated over time. The number and time of cycles depends on the type of fabric and will be specified in the relevant specification. 3. Abrasion tester for pilling test: Specimens are mounted on large (bottom) and small (top) specimen holders. Then rub against each other (source sample). 2 The pressure is: 2.5/cm of knitted fabric. Woven and upholstery fabrics 6.5. In standard abrasives, fabric samples are placed on the lower rack. If the pilling degree differs from the rack, the upper sample is evaluated. The number and time of cycles depends on the type of fabric tested and will be specified in the relevant specification.
