Abstract
Pilling resistance is an important property of the knitted fabric. The main purpose of this research work is to provide precise and appropriate test result requirements for different types of knit fabrics with different fiber compositions. The Pilling test result requirement cannot be the same for different types of knit fabrics. But unfortunately, almost the same requirements are mentioned in the quality manual of buyers for knit fabrics with different fiber compositions. In real life, the requirement should be different and this research work was conducted keeping this issue in mind. In this work, the test standard ISO 12945-2 was used in this research work in where NU Martindale Pilling tester used with different pilling cycle/rubs e.g. 1000, 2000, 5000, and 7000 rubs. It was noted that the higher the pilling cycle/rub, the lower the pilling test result and this is the most important outcome from this study. The textile industry, buyers, suppliers, fabric manufacturers, students would be benefited if follow the suggested pilling requirement. Due to the limitations of availability of fabric samples; the researcher used five different types of knit fabrics such as 100% cotton single jersey, 100% cotton double jersey (1X1 Rib), Lycra single jersey (95% cotton 5% Lycra), 100% polyester Fleece, Blended Fleece fabric (60% cotton 40% poly). The future scope is there to conduct this type of research for woven fabrics also. Many researchers worked on pilling properties using this NU Martindale equipment but no study was conducted on the pilling cycles/rubs to see the effect on pilling results and this research work is a new one.
