本文介绍了一项旨在提高聚酯纤维亲水性能的原创技术。在该方法中，芳环的磺化是使用通过紫外线照射活化的气态三氧化硫进行的。因此，将聚酯织物暴露在三氧化硫流下的 UVC 光（波长约 254 nm）下会导致 -SO3H 基团的固定。固定磺酸基的量取决于反应条件。通过接触角测量、回潮率以及通过测量保留率来进行从吸湿性能测量中推断出的接枝证据。 SEM 和 FT-IR 分析、DSC 和 DTA/TGA 热分析图表明，大部分经过处理的 PET 织物没有发生明显的变化。 (C) 2012 Elsevier B.V. 保留所有权利。
This paper describes an original technique aiming to improve the hydrophilic properties of polyester fibres. In this method, the sulfonation of the aromatic rings is carried out using gaseous sulfur trioxide activated by UV irradiations. Thus, exposing the polyester textile fabric to the UVC light (wavelength around 254 nm) under a stream of sulfur trioxide leads to the fixation of -SO3H groups. The amounts of the fixed sulfonate groups depended on the reaction conditions. Evidence of grafting deduced from the measurements of hygroscopic properties was carried out by contact angle measurement, moisture regain as well as by measuring the rate of retention. SEM and FT-IR analysis, DSC and DTA/TGA thermograms showed that no significant modifications have occurred in the bulk of the treated PET fabrics. (C) 2012 Elsevier B. V. All rights reserved.
