INFLUENCE OF PILLING ON THE STRUCTURAL CHARACTERISTICS OF FLAX PLAIN WEFT-KNITTED FABRICS

Abstract

In this study, the structural characteristics of plain weft-knitted fabrics both before and after pilling were analyzed, and evaluated their tendency to develop surface fuzz and pilling. Five knitted fabrics made from flax yarn, each with different structural features as the number of wales, courses, mass per unit area, and thickness, were examined. To induce pilling, a Martindale device with two different abrasives: the investigated knitted fabric and a wool woven fabric, was used. The obtained results revealed that the grade of pilling decreased as the number of rubs increased, and that using the investigated knitted fabric as an abrasive resulted in lower grades of pilling. Regardless the pilling was caused by the investigated knitted fabric or the wool woven fabric, a reduction in all examined structural characteristics of the knitted fabrics after pilling, was observed.

U radu su ispitivane strukturne karakteristike desno-levih kuliranih pletenina, pre i posle pilinga. Takođe, procenjena je i sklonost pletenina ka promeni maljavosti i sklonost ka pilingu. Ispitivanja su obuhvatila pet pletenina proizvedenih od istog lanenog prediva, ali različitih strukturnih karakteristika (broj nizova, broj redova, površinska masa i debljina). Pilling je generisan na Martindale-ovom uređaju upotrebom dva različita abraziva (ispitivana pletenina i vunena tkanina). Dobijeni rezultati su pokazali smanjenje ocene pilinga sa povećanjem broja pokreta abraziva; te ocene su niže u slučaju kada je ispitivana pletenina korišćena u svojstvu abraziva. Piling je doveo do smanjenja svih ispitivanih strukturnih karakteristika pletenina, kako nakon pilinga izazvanog ispitivanom pleteninom tako i nakon pilinga izazvanog vunenom tkaninom.
