摘要

全氟烷基和多氟烷基物质被广泛用于在某些织物整理中提供疏水和疏油屏障。全氟烷基和多氟烷基物质是一类持久存在于环境和我们身体中的有害化学物质。对于室内装饰,这些饰面用于防止污染。在这项研究中,我们检验了某些全氟烷基和多氟烷基物质在商用室内织物上的拒液性和染色性能的有效性。用咖啡和油基沙拉酱污渍、两次停留时间、两次污渍施加程序和三种磨损条件测试了三种织物,每种织物都有一个未完成的对照、一个浸渍表面和一个泡沫表面。油污的严重程度受织物类型、光洁度、停留时间和使用程序的影响,但不受磨损的影响。对于水性咖啡污渍,只有织物类型有影响。还进行了液滴接触角测试,揭示了斥水性和拒油性随着磨损而迅速丧失。在测试的六种全氟烷基和多氟烷基物质成品织物中,有五种织物的染色性能比未成品织物略有改善;然而,织物类型之间的性能差异远大于整理带来的好处。对于油渍,全氟烷基和多氟烷基物质饰面有助于在理想的条件下,当饰面未磨损,污渍轻轻地附着在织物上,污渍可以快速清洁。我们的研究结果表明,通过有意选择材料,可以大大减少全氟烷基和多氟烷基物质在室内家具上的使用,以实现更好的染色性能,而不是全氟烷基或多氟烷基材料饰面。

Evaluating the Performance of Per- and Polyfluoroalkyl Substance Finishes on Upholstery Fabrics
Per- and polyfluoroalkyl substances are widely used to provide a hydrophobic and oleophobic barrier in some fabric finishing. Per- and polyfluoroalkyl substances are a class of harmful chemicals that persist in the environment and our bodies. For indoor upholstery, these finishes are used to prevent staining. In this study, we examined the effectiveness of certain per- and polyfluoroalkyl substance finishes on commercial indoor fabrics for liquid repellency and stain performance. Three fabrics, each with an unfinished control, a dip finish, and a foam finish, were tested with coffee and oil-based salad dressing stains, two dwell times, two stain application procedures, and three abrasion conditions. Oil stain severity was affected by fabric type, finish, dwell time, and application procedure, but not abrasion. For water-based coffee stains, only fabric type had an effect. Droplet contact angle tests were also performed, revealing water and oil repellency is quickly lost with abrasion. Of the six per- and polyfluoroalkyl substance-finished fabrics tested, five showed small improvements in stain performance over unfinished fabrics; however, the performance differences between fabric types were much larger than the benefits from finishes. For oil stains, per- and polyfluoroalkyl substance finishes help in ideal conditions when the finish is unabraded, stains are set gently on the fabric, and stains are cleaned quickly. Our results suggest that the use of per- and polyfluoroalkyl substances on indoor furniture can be considerably reduced through intentional material selection to achieve better stain performance in lieu of per- and polyfluoroalkyl substance finishes.
