An Exploration on Pilling Attitudes of Cotton Polyester Blended Single Jersey Knit Fabric After Mechanical Singeing

This article presents the pilling attitude of different cotton polyester ratio blended yarn single jersey knitting fabric after mechanical singeing. Four different blended yarn (80% cotton 20% polyester, 60% cotton 40% polyester, 52% cotton 48% polyester, 35% cotton 65% polyester) were selected and knitted in two different 180 & 120 GSM, containing 10 kg for each composition for GSM variation. All the samples were singed first on both sides of fabric, processed with scouring and bleaching and finally degree of pilling was evaluated and compared with the unsigned processed samples. The target was to compare the pilling tendency of different blends before and after singeing process. Pilling test was accomplished by ISI pilling box machine obeying ISO 12945-1:2000 standard method where eight specimens were tumbled in pilling box for 11,500 number of revolutions. Finally it was found that mechanically singed samples show good pilling grade ( 3-4) than that of without singed samples (1-2) and higher Presence of polyester fibre on blended yarn affects the pilling attitude of the fabric to a down grade for both higher and lower GSM. It was also perceived that higher GSM fabrics have more pilling tendency than lower GSM for each without singed and after singed samples.
