Optimizing bursting behavior of calendered needle-punched polyester fabrics

Abstract

In the present study, two sets (I and II) of needle-punched nonwoven fabrics using virgin and recycled polyester fibers were prepared varying machine parameters. In the set first (set I) three different parameters namely grams/m2 (GSM), needling density and blend ratio with three different levels and in the second set (set II) three different parameters, i.e. calender roller pressure, calender roller temperature and calender roller speed with three different levels were used. For the first set fabrics, it has been seen that the bursting strength increased with the increase in GSM, needling density as well increased virgin polyester fiber in the blend. In the second set increase in calender roller pressure, roller temperature caused increase in bursting strength, but with the increase in roller speed it decreased. The comparison of both sets fabric revealed that set II fabric formation is economical since there is less consumption of polyester fibers. The investigation of two arrangements of fabrics uncovers that legal choice of calendering parameters may result economical nonwoven fabrics by requiring lesser fibrous strands for the assembling of needle bonded fabrics, moreover it will lessen the contamination by using the waste polyester bottles additionally the reliance on normal oil-based virgin polyester will be reduced.
