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.

UV-C辐照引起的PVP在PES / CO针织织物上的交联:纺织品性能和表面评价

针织物广泛用于纺织和服装工业。但是,尺寸变化(DC)和起球可能会在生产过程中以及使用后发生。为减少这些不良影响,在50:50%的聚酯/棉(PES / CO)针织织物上进行了具有聚(N-乙烯基-2-吡咯烷酮)(PVP)并通过UV-C辐射交联的聚合物涂层。交联过程的影响通过DC测量(在横纹和纵行方向上),起球程度,疏水性和抗爆强度的测定来评估。红外傅里叶变换光谱和扫描电子显微镜被用来评估织物的表面。
