A Novel Natural Source Sterculia foetida Fruit Shell Waste as Colorant and Ultraviolet Protection for Linen

ABSTRACT

There has been a growing interest in natural dyes and consciousness about ill effects of ultraviolet rays on the human skin. This paper discusses dye extraction from the fruit shell waste of Sterculia foetida and its application on linen fabric for dyeing as well as ultraviolet protection (UPF) property. Optimal results were achieved for dyeing at 90°C for 60 min at 30% concentration of the dye on the weight of fabric using pre- and post-mordant dyeing techniques. Dyeing on linen fabric with and without mordant showed very good results in terms of different hues of color and UPF. Treated fabrics showed substantial increase in color depth and good to very good wash, light and rubbing fastness properties for both with and without mordant-dyed linen fabrics. The results confirmed that natural dye from Sterculia foetida fruit shell extract has potential applications for linen dyeing and producing a good to very good UPF.

摘要

人们越来越关注天然染料和紫外线对人体皮肤不良影响的意识。本文从掌叶苹婆和染色以及紫外线保护亚麻织物上的应用果壳废物对染料的提取（UPF）财产。采用媒染前后媒染法，在染料浓度为30%的织物上，在90℃下染色60分钟，达到最佳效果。在亚麻织物上有无媒染得到了很好的结果在不同的色调的颜色和UPF的条款。处理后的织物颜色深度显著增加，对亚麻染色织物和未经染色的亚麻织物有很好的水洗、日晒和摩擦牢度。结果证实，从Sterculia foetida果壳中提取天然染料对亚麻织物染色，产生一个很好很好的UPF的潜在应用。
