ABSTRACT

In this work, silkworm cocoon waste is used to make needle-punched nonwoven to study the oil sorption characteristics. The contact angles, oil sorption and retention capacity, sorption capacity after repeated use, and biodegradability of silk nonwoven are investigated. The oil sorption capacity of silk nonwoven fabrics against crude oil and vegetable oil are 31.52 g/g and 25.92 g/g respectively. The silk fibers are hydrophobic and oleophilic indicated by the contact angles. The study showed that silk nonwoven fabrics can be reused effectively at least five times before being disposed-off. The silk nonwoven biodegrades completely in soil in 100 days. The present work indicates that the silk nonwoven is a potential candidate for sustainable oil spill removal.

摘要

在这项工作中，将蚕茧废料制成针刺无纺布，以研究其吸油特性。研究了丝绸非织造布的接触角，吸油量和保留能力，重复使用后的吸附能力以及生物降解性。丝绸无纺布对原油和植物油的吸油量分别为31.52 g / g和25.92 g / g。丝纤维是疏水的和亲油的，由接触角表示。研究表明，丝绸无纺布在被处理之前至少可以有效重复使用五次。丝绸无纺布可在100天之内在土壤中完全降解。目前的工作表明，丝绸非织造布是可持续清除溢油的潜在候选者。
