Study on pilling of textiles and pill box geometry

Abstract

Pilling studies of selected textile materials such as 100 % Cotton, newlineViscose, Linen, P/C (80/20), P/C (65/35) and P/V (70/30) have been carried newlineout on pill boxes with different geometrical shapes as a novel attempt. Thus newlinepill boxes with various geometrical shapes have been designed and developed newlinesuch as Cubical, Triangular, Hexagonal, Octagonal and Cylindrical. Pilling newlinestudy of the selected samples in all these boxes are carried out for definite newlinenumber of revolutions such as 5000, 10000, 15000 and 20000. The results of newlinepilling are presented and discussed systematically first as the pilling of all the newlinetextile materials in a selected pill box geometry as per the order cubical, newlinetriangular, hexagonal, octgonal and cylindrical. Then they are compared in newlineterms of material wise over all the boxes. Such analysis clearly reveals that newlinethe hexagonal box is efficient in pilling of textiles than the other geometrical newlineshaped pill boxes. Among the materials, the P/C (65/35) has shown high newlinepilling. As a common trend in all these woven fabrics, pilling increases with newlinecertain number of revolutions and then it starts decreasing. It is explained newlinewith the detailed mechanism of pill formation and falling with suitable newlineschematics with 7 distinct stages.Further, the pilling results are subjected to theoretical analysis considering the various possible kinetics of the sample tubes inside the pill newlineboxes. Theoretical analysis revealed that as the number of polygon side newlineincreases, the total sample tube movement increases leading to continuous newlinemotion as in cylindrical box, single impact force decreases while the total newlineimpact force of the sample remain same. newline Pilling studies of selected textile materials such as 100 % Cotton, newlineViscose, Linen, P/C (80/20), P/C (65/35) and P/V (70/30) have been carried newlineout on pill boxes with different geometrical shapes as a novel attempt.
