  Abstract

Knitted fabrics are widely used in the textile and garment industry. However, dimensional change (DC) and pilling can occur during production and also after use. To reduce these undesirable effects, a polymeric coating with poly(N-vinyl-2- pyrrolidone) (PVP) and crosslinking via UV-C irradiation was performed on a 50:50 % polyester/cotton (PES/CO) knitted fabric. The influence of the crosslinking process was evaluated through DC measurements (in the direction of the courses and wales), determination of the degree of pilling, water repellency and bursting strength. Infrared Fourier transform spectroscopy and scanning electron microscopy were used to evaluate the surface of the fabric. The results indicate that the PVP crosslinked with UV-C irradiation on the PES/CO surface decreased the degree of pilling (grade 4 for the coated knitted fabric compared with grade 1 for the uncoated knitted fabric) and the DC, without influencing the hydrophilicity and bursting strength.
