Green dyeing process of modified cotton fibres using natural dyes extracted from Tamarix aphylla (L.) Karst. leaves

Abstract

This research work involves an eco-friendly dyeing process of modified cotton with the aqueous extract of Tamarix aphylla leaves. During this process, the dyeing step was carried out on modified cotton by several cationising agents in order to improve its dyeability. The influence of the main dyeing conditions (dye bath pH, dyeing time, dyeing temperature, salt addition) on the performances of this dyeing process were studied. The dyeing performances of this process were appreciated by measuring the colour yield (K/S) and the fastness properties of the dyed samples. The effect of mordant type with different mordanting methods on dyeing quality was also studied. The results showed that mordanting gave deeper shades and enhanced fastness properties. In addition, environmental indicators (BOD, COD and COD/BOD) were used to describe potential improvements in the biodegradability of the dyebath wastewater. Further, HPLC was used to identify the major phenolic compounds in the extracted dye.

Study of Cotton Fabric Dyeing Process With Some Mordant Methods By Using Gambier (Uncaria gambir Roxb) Extract

“…Applications of natural dyes are increased because of the biodegradability properties and high compatibility with the environment [3]. Fabrics with natural dyes have soft, low toxic, hypoallergenic colors, and antibacterial potential [4]- [6].…”

“…Plant of colorants source that grows in Indonesia are quite abundant, but they were not all explored yet. The colors produced are depended on the type of plant, and mordant used [6]- [8]. Gambier (Uncaria gambir Roxb) is one of the potential industrial crops and are produced in various regions especially in West Sumatra by the form of raw gambier.…”

A Novel Coloration of Polyester Fabric through Green Silver Nanoparticles (G-AgNPs@PET)

“…The coloring process typically involves a number of operations including dyeing, pigmenting and printing [1] and as a result releases large amounts of contaminated colored wastewater, which is considered to be a significant environmental pollutant due to its recalcitrant chemical nature (e.g., dyes/pigments) [2,3]. Many efforts are ongoing regarding the establishment of green textile coloration in terms of cost effectiveness and producing harmless non-contaminant materials associated with the subsequent process [4,5,6]. In recent years, the introduction of nanotechnology in the textile coloration process has provided a viable option to meet the current scenario [7,8,9].…”

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

“…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. Natural dyeing for multifunctional modification of linen has been reported to a limited extent.…”
