“…Dyeing of knitted fabrics made of PLA fibers and comparable PET was performed using natural orange, natural red brown, turmeric, and cassumunar dyes. 43,44 Sidarkote et al 45 introduced the dyeing of PLA fabrics by exhaust dyeing with natural indigo dye, Indigofera tinctoria. Emodin natural dyes have also been described to give bright colors and brilliant color fastness on PLA knitted fabrics.…”

Juglone is a naphthoquinone-type dye. It is also known as a C.I Natural Brown 7 dye and is used to dye natural and synthetic fibers. This article presents the possibility of using juglone as a natural colorant for biodegradable polymers (polylactide and polyhydroxybutyrate). Based on the results of the research, it was shown that juglone added to biodegradable aliphatic polyesters does not change the properties of the polymers, such as mechanical properties and thermal stability. Noteworthy is the change in the color of the materials under the influence of various external factors, such as temperature, humidity, and UV radiation. Juglone can be used as an indicator of the aging time of polymeric materials. The presented materials, made of biodegradable polymers with a dye of plant origins, may potentially be applied to packaging materials with controllable lifetimes. The scientific novelty of this paper is the use of juglone as a natural dye and as an indicator of the aging time of biodegradable polyesters (polylactide and polyhydroxybutyrate).

“…PLA is reported to give higher shade depth with curcumin as compared to PET at the same dye concentration (Sriumaroum et al, 2011). °C for 60 min (Sidarkote et al, 2014). Emodin natural dyes have also been reported to give bright color and excellent color fastness on PLA knitted fabrics (Wu and Ke, 2011).…”

“…However, dyeing at lower temperatures results in poor dye take-up compared to PET [3,10,11]. The exhaust dyeing of PLA with indigoid compounds is possible at 110 • C [11,12]. Furthermore, PLA fibers modified with polyhedral oligomeric silsesquioxane nanoparticles also showed better dyeability than pure PLA [13].…”

Effect of Colorants and Process Parameters on the Properties of Dope-Dyed Polylactic Acid Multifilament Yarns

et al. 2022

The color of textile fibers is typically imparted by submersion in a high-temperature dye bath. However, the treatment of the effluent is challenging and the textile industry is therefore a major source of water pollution. Current fashion trends favor biobased polymers such as polylactic acid (PLA) but exhaust dyeing at high temperatures causes hydrolytic degradation, reducing the crystallinity and tenacity of the yarn. To preserve the mechanical properties of PLA-based textiles, an alternative to exhaust dyeing called dope dyeing can be used, wherein colorants are incorporated into the polymer matrix during melt spinning. We evaluated this process by dope dyeing PLA with several colorants, then testing the thermal, physical, and mechanical properties of the yarn and the physical properties of circular-knitted fabrics. Although the colorants affected the crystallization behavior at lower cooling rates, during the melt-spinning process, the drawing speed had a greater effect on the crystallinity and mechanical properties of the dyed yarn. Scanning electron microscopy revealed that the colorants were well dispersed in the PLA matrix. We found that the colorants did not affect the physical properties of the knitted fabric. Our results can be used to develop more environmentally beneficial dope-dyed PLA yarn with improved mechanical properties.
