Testing Acorn and Oak Leaves for the UV Protection of Wool Fabrics by Dyeing

ABSTRACT

Different approaches for the functional finishing of textile are now assessed as the popular subjects. In this respect wool fabrics were dyed with the leaves of oak and acorn (the different parts of the oak tree). The dyeing processes were carried out by using different mordants in different mordanting-dyeing processes. The samples were then investigated in terms of the obtained colors, fastness values, and UV protection features. It was observed that by use of acorn and oak leaves, the wool fabrics can be colored even when the mordanting agents were not used. In that case, the fastness values to washing, rubbing, and light were perfect too. Addition of the different mordanting agents caused different colors. Generally brown colors in different shades were obtained during the studies and the mordanting method was also found as responsible for the differences in obtained colors. Meanwhile, it was observed that the undyed wool has exhibited an UV protection feature but by using different natural dye sources, the UV protection feature of the fabrics was significantly increased. It was also found that UV protection properties of the fabrics increased with only mordants (without dyeing) as well.

摘要

纺织品功能整理的不同方法现在被认为是热门课题. 在这方面，羊毛织物用橡树和橡子（橡树的不同部分）的叶子染色. 在不同的媒染剂染色工艺中，采用不同的媒染剂进行染色. 然后根据获得的颜色、牢度值和紫外线防护特性对样品进行调查. 据观察，使用橡子叶和橡树叶，即使不使用媒染剂，羊毛织物也可以着色. 在这种情况下，耐洗、耐摩擦和耐光的牢度值也非常理想. 添加不同的媒染剂会导致不同的颜色. 在研究过程中，通常会获得不同色调的棕色，并且发现媒染剂方法也是造成颜色差异的原因. 同时，观察到未染色羊毛具有紫外线防护特性，但通过使用不同的天然染料源，织物的紫外线防护特性显著增强. 还发现，仅使用媒染剂（不染色）也可提高织物的紫外线防护性能.
