  • Polyester fabrics and knits were corona treated with different current intensity (5, 10, 15, 20 A) and feeding speed (5, 10, 15 m/min). We confirmed the surface change of polyester fabrics and knits using scanning electron microscopy (SEM) and X-ray photoelectron spectrometer (XPS). And the change of physical properties through measuring the tensile strength, dry and wet bonding strength. Thermosetting reactive polyurethane hot melt adhesive was used in the adhesion of polyester fabrics and knits. Functional groups were introduced on PET fabrics and knits surface by treating the PET fabrics and knits in air atmosphere with corona discharge, and take placed unevenness, the result adhesion was improved. When consider both dry and wet bonding strength, we think that appropriate conditions in the PET fabrics corona treatment are feeding speed 10 m/min, current intensity 15 A and appropriate conditions in the mesh type PET knits corona treatment are feeding speed 10 m/min, current intensity above 10 A.

  • To Save energy and cost one bath/one step dyeing and finishing on cotton/polyester blends is carried out with disperse dyes in the presence of crosslinking agent. Cotton 100 %, cotton/polyester 70/30, 50/50, 35/65, polyester 100 % fabrics were used. wrinkle recovery angle, tensile strength retention and tearing strength retention were determined in according to the dyebath composition, and also determined while the concentration of DMDHEU, molecular weight and concentration of PEG were varied. Colorfastness to abrasion, washing and light were tested. For cotton and cotton/polyester blends dyed in the presence of DMDHEU/PEG, wrinkle recovery was improved. Tensile strength retention and tearing strength retention were decreased, in compared with dyed fabrics without DMDHEU. Colorfastness to abrasion was good but colorfastness to washing and to light were poor for the fabrics dyed in the presence of DMDHEU/PEG.
