Study regarding the physical-mechanical properties of knits for garments – pilling performance

摘要

The effect of the pilling degradation results is an important decreasing in garment quality and a negative influence on the user’s comfort to wear. There are a lot factors, such as the yarn spinning system, fabric geometry and finishing operation, which affect the pilling performance. This research paper presents the investigation of fabric surface concerning pilling formation, especially knits, influenced by the fibrous composition. As samples were used knitted fabric panels, obtained from carded yarns, with fibers composition like cotton, wool or mixed one. Regarding fabric geometry 3 types were used – single jersey, 2x2 rib and moss stitch. In order to establish which of the yarns are most appropriate for knitting garments from the point of view of pilling resistance were realized tests using the standard SR EN ISO 12945-2.The tests were performed with the Nu-Martindale – Abrasion and Pilling Tester, Model 864.For assessment were used two methods – the first one is a comparison with visual standards, tested fabrics or photographs of fabrics, to find the degree of pilling on a scale from 5 (no pilling) to 1 (very severe pilling) and the second one by determination of mass loss percent.
