摘要：
In view of the problem of poor hydrophilicity of polyester, the surface modification of polyester fabric was carried out by low temperature plasma. The influence of dielectric barrier discharge plasma on the performance of polyester fabric was investigated under the pressure of 300 Pa and power of 5.5 W. The dynamic friction coefficient, strength, hydrophilicity and other properties of the treated fabric were measured, and the microscopic morphology and surface chemical composition of the polyester fiber were characterized. The mechanism of plasma-modified polyester was proposed. The results show that the plasma etches the polyester surface to generate cracks and voids on the surface of the fiber, which increases the surface area of the polyester fiber. The dynamic friction coefficient increases with the increase of plasma treatment time, and the strength decreases by up to 25% with the increase of treatment time. The capillary effect of the treated fabric is increased by 75%, the contact angle to water is reduced by 33.3%, and the surface hydroxyl of the polyester is increased, which effectively improves the hygroscopicity and hydrophilicity of the polyester. The plasma treated polyester has certain timeliness. Copyright No content may be reproduced or abridged without authorization.
