Efficient mothproofing of wool through natural dyeing with walnut hull and henna against Dermestes maculatus

Abstract

There is a growing need for eco-friendly mothproofing property owing to stringent environmental regulations. One type of insects responsible for critical damage of the usual protein wool fabric is the hide beetle Dermestes maculatus. In this research, efficient mothproofing procedure is introduced through natural dyeing of protein wool fabric with walnut hull and henna as environmental friendly dyes. The wool fabrics were first mordanted with aluminum sulfate and then dyed with walnut hull and henna dyes. The mothproofing properties of control, walnut hull, and henna-dyed wool samples were evaluated statistically. Mothproofing was assessed through the study of damages on wool surface by the larvae of hide beetle, Dermestes maculatus, as feeding protein fibers and wool weight loss (%) were measured. The damage intensity of wool fabric surface was confirmed with scanning electron microscopy images. The analysis of variance was utilized to obtain the optimum conditions for mothproofing. Further, reflectance and absorbance of wool samples were reported. Finally, the experimental results indicated highest protection against Dermestes maculatus on the both walnut hull and henna-dyed protein wool.

Enhanced insect-resistance, UV protection, and antibacterial and antistatic properties exhibited by wool fabric treated with polyphenols extracted from mango seed kernel and feijoa peel

“… 26–28 Recently, researchers looked back to nature and plant extracts of henna, and walnut hull also have been investigated as an alternative to synthetic pyrethroids. 29 …”

Application of natural yellow (curcumin) dye on silk to impart multifunctional finishing and validation of dyeing process using BBD model

“…Therefore, the use of those dyes (eg, azo dyes) is banned all over the world. Due to toxic nature and adverse effects of synthetic dyes, the interest in natural dyes is increasing throughout the world in the last few years 7‐12 …”

Antibacterial, Uv Protective and Antioxidant Linen Obtained by Natural Dyeing With Henna

“…10 Nazari et al investigated dyeing of wool using henna and walnut hull dye, and aluminium sulphate as a mordant, and found efficient mothproofing of dyed wool fabric against Dermestes maculatus. 11 As cellulosic fibers are difficult to dye with natural dyes, as compared to protein-based fibers, innovative methods, such as cationization of fabric, plasma treatment coating of fabric with chitosan, the use of enzymes and ultrasound during dyeing, to improve the dyeability have been reported. [12][13][14] Linen is a fiber that has been gaining increased interest, and is now widely used for various products, such as garments, bed sheets and home textiles.…”
