Study on the Dyeing Properties of Poly(Lactic Acid) and Silk Yarns with Natural Dyes

Abstract

This research aimed to study the dyeing properties on the PLA and silk yarns of the natural dyes obtained from various materials, viz. marigold petals (Tagetes erecta L.), rhubarb rhizomes (Radix et Rhizoma Rhei), garcinia barks (Garcinia Dulcis Kurz), turmeric rhizomes (Curcuma Longa Linn.), sappan barks (Caesalpinia sappan Linn.) and catechu barks (Acacia catechu Willd.). The color properties of the dyed yarns was determined and compared. The results observed the different color properties (L*, a* and b* values) and a shift of λmaxof the dyes on the PLA and silk yarns. This change in color properties of each natural dye was expected to be affected by the types of substrate (textile fiber) and also the chemical nature of the natural dyes. The study of the build-up properties indicated that the turmeric dye is the only natural dye which showed an outstanding performance on PLA and silk. A high degree of color yield of turmeric dye was obtained on both yarns, whereas a poor build-up was observed for the rest of the dyes.

The potential of juglone as natural dye and indicator for biodegradable polyesters

“…Among the examined dyes, only turmeric dye gives a high degree of color yield on PLA. 41 Wu et al 42 described the kinetics and thermodynamics of dyeing PLA fibers with curcumin (turmeric). Dyeing of knitted fabrics made of PLA fibers and comparable PET was performed using natural orange, natural red brown, turmeric, and cassumunar dyes.…”

Poly(lactic acid) fibers, yarns and fabrics: Manufacturing, properties and applications

“…The results showed that only the turmeric dye performed well on PLA. 147 Like disperse dyes, the addition of POSS nanoparticles enhanced the dyeability of natural dyes. 148 PLA fabrics have also been dyed with vat dyes.…”

Eco-Dyeing of Silk Fabric withGarcinia Dulcis(Roxb.) Kurz Bark as a Source of Natural Dye by using The Padding Technique

“…In Java, the bark is used to dye mat (Lim 2012). G. dulcis is one of the most important sources of natural dye that gives a yellow colorant (Ujjin and Suesat 2012;Nakpathom et al 2012). The trunk, fruit, and the bark of the G. dulcis is shown in Figure 1.…”
