Abstract
The grafting of acrylic acid(AA), hydrophilic vinyl monomer onto Nylon 6 fiber in the presense of ammonium persulphate(AP) has been investigated. The grading yield AA onto Nylon 6 (ibex was increased with increment of AA concentration and then reached it's maximum in presense of 0.05%AP. In case of time, the grafting yield increased rapidly up to 60 min. and then decreased gradually. The morphological change of surface of AA-g-Nylon 6 fiber by SEM with increasing of grafting yield exhibited gradual development of irregular fissure on the snlootil surface. The moisture regain of AA-g-Nylon 6 was slightly increased, but that of Na-g-Nylon 6 was remarkably increased. The fiictional electrostatic charge of Na-g-Nylon 6 fiber with increasing grafting yield was developed little. The changes of mechanical properties of fabrics, bending rigidity(B), hysteresis of bending moment(2HB), shear stiffness(G), and hysteresis of shear force at 5° of share angle were increased, which indicated much increase of KOSHI and HARI value and decrease of SHINAYAKASA.
