摘要
聚酯纤维因分子结构对称、结晶度高、亲水性较差等导致其穿着舒适性及可染性较差,本文采用等离子体方法进行改性,测定改性纤维的上染率并分析浸润特性和纤维的表面能。通过等离子体处理后的纤维上染率明显比未处理的纤维上染率要高,可以将A染料的上染率提高到85%。改性纤维的浸润性明显改善,水中的接触角由原来的64.8°降低到18.8°,表面能和极性分量亦明显提高,改性纤维的表面能可达70.807×10-7J/cm2,极性分量达到54%,而色散分量降低至45%。说明等离子体改性效果明显。
Because of polyester has a symmetrical molecular structure,high crystallinity,poor hydrophilic,as a re sult it has poor wearing comfort and dyeability.In this paper,dyeing rate of modified fiber,analysising its wetting characteristics and the surface energy of fiber was delermined by the plasma to modified the polyester.The dyeing rate of plasma-treated fiber is significsntly higher than the untreated fiber,it can increase the dyeing rate of dye A up to 85%.The wettability of modified fiber is significantly improved,the contact angle in water reduce to 18.8 ° from 64.8°.Surface energy and polar component also improve significantly,the surface energy of modified fiber can be up to 70.807 × 10-7J.cm2,polar component can be up to 54%,but the dispersion component is reduced to 45%.These all explain that the effect of plasma odification is obvious.
