Multifunctional Finishing of Woolens with Lemongrass Oil

ABSTRACT

In the reported work, lemongrass oil was coated on the wool fabrics to impart multifunctional finish. During the treatment, chitosan was used as a crosslinking agent. The coated fabrics were characterized using SEM, EDX, FTIR and computer color matching in addition to mechanical and handle associated properties. The effect of coating was analyzed on the three functional properties viz., moth repellence, UV protection and aroma of the fabric. During the moth repellence test, the lemongrass treated wool fabrics showed higher moth mortality (80%) and less weight loss (14%). The UV protection factor (UPF) was also found higher (127) than the untreated wool fabric (44). The coated fabrics retained aroma even after 90 days of storage. This environment-friendly fabric coating can be applied to different types of woolen products and other textiles for value addition.

摘要

以宁夏地区特色植物红柳为原料, 使用管式炉和球磨机制备炭化红柳纳米颗粒 (CRN), 将0wt%, 0.25wt%, 0.5wt%, 0.75wt%, 1wt%的CRN添加到树脂中, 采用真空辅助树脂灌注(VARI)工艺制备复合材料。研究CRN含量的改变对竹纤维环氧树脂复合材料拉伸, 短梁剪切和低速冲击性能的响应规律。结果表明, CRN为0.5wt%时的拉伸强度最大, 提高18.35%CRN为0.25wt%时的短梁剪切强度最高, 提升了38.96%, CRN为0.5wt%的板材峰值载荷最大, 吸收能量最小, 刚度最大。
