Magnetic Cotton Fabric Coated with Poly (vinyl alcohol) (PVA)/ Magnetic Attapulgite (MAT) Composite Solution

TQ050.4+3; Magnetic fiber or fabric incorporating magnetic particles was widely used in the field of magnetic health-care.The cotton fabric was modified with poly (vinyl alcohol) (PVA)/magnetic attapulgite (MAT) composite solution by coating,which was the PVA solution blended with MAT.The mechanical and magnetic properties were characterized by scanning electronic microscopy (SEM),vibrating sample magnetometer (VSM) and tensile strength test.The results of SEM show that MAT can scatter uniformly in the PVA film and the PVA/MAT polymer film has good combination with cotton fabric.The results of other tests show that the addition of PVA/MAT polymer film not only brings uniform magnetism to cotton fabric,but also increases the mechanical strength of the material.Besides,the proportion of PVA/MAT and dipping time are studied in order to determine the best parameters for further study on magnetic cotton fabric.
