Use of synthetic dyes for dyeing of textile fabrics is most problematic environmental concerned for textile industry. The demand of natural colourants for the dyeing of textile fabrics has been increasing. Thus, sustainable novel technologies for textile dyeing are needed that utilize improved colour strength and enhanced performance characteristics of the fabric. This study attempts to highlight the possibility of using cochineal natural dye in the printing of polyester fabrics after surface modification by O2/Ar plasma treatment. The colour strength, air permeability, crease recovery angle of printed fabrics, colour fastness to rubbing, washing and light, were also studied. The surfaces of untreated and plasma-treated polyester fabrics were analysed by SEM to compare the morphological changes. Surface roughness and cracks were indicated after the plasma pretreatment. The results indicated that plasma treatment could improve the printability of polyester fabric compared with untreated samples, with enhanced the adhesion and penetration of printing paste to the surface. The air permeability of printed fabrics has decreased, while the angle of crease recovery has increased. The fastness properties of printed samples were found suitable to very good.

Abstract: Dying is a popular practice in textile industry which is prevalent at all parts of the world from the period of ancient civilization. Initially, natural dyes i.e. dye derived from natural resources like vegetables, flowers, minerals, plants etc. were used. Now-a-days, due to technological and scientific innovations synthetic dyes are processed at large scale in the laboratories as it is still one of the most profitable industry globally. However, the rapid utilization of chemicals in textile industry for production of synthetic dyes causes degradation of environment like soil pollution, water pollution etc. Hence, it is necessary to promote the utilization of natural dyes globally. In this paper, the bleached silk fabric was dyed with Indian Madder natural dye at different temperature and the colour strength is measured spectrophotometrically in order to study the effectiveness of the dye.

Abstract In the textile sector, the utilization of synthetic dyes is environmentally unfriendly and has a very harmful impact on human health and the environment. Hence, natural dye is assumed to be a suitable alternative for sustainable textile manufacturing and colouration, but it remains challenging to prepare the dyes having high stability with textile fablric. Herein we have demonstrated the dyeing process for cotton fabric with natural dye extractions from turmeric (Curcuma longa L.) and tea (Camellia sinensis) in the presence of mordant. Subsequently, we have prepared copper and 2-methyl 8-hydroxyquinoline functionalized graphene oxide (GO) (CHG) trinary-composite as mordant to improve the stability and colour strength of naturally extracted dyes. The prepared trinary-composite was investigated using various techniques such as FTIR, XRD, UV, and TGA analysis. To evaluate the effect of CHG composite, it mixed with natural extracted dyes such as turmeric and tea dyes, converted to CHG functionalized turmeric and tea dyes (TuCHG and TeCHG) for the dyeing of cotton fabric. TuCHG and TeCHG dyed cotton fabrics exhibited superior colourfastness, wash fastness and rub fastness in comparison to only turmeric and tea dyes dyed cotton fabrics. TuCHG and TeCHG dyes also demonstrated decent antibacterial properties. The present study indicates the new aspect for prepared mordant to increase natural dye colour strength and stability. Thus, this process is a much safer, cost-effective and sustainable method for the application of natural dyes with enhanced substantively for cotton fabric.

Dye Industry

Textiles sectors serve up the outfit needs of every day and this industry plays a major role in the economy of the country. All the textile fabrics are either natural or synthetic fibers or a blend of both. Different types of dyes are used for different kinds of fabrics depending on the nature and type of the fabric to be dyed, to impart color, modify the fabric to make them more attractive and astonishing. In short, the introduction of synthetic dyes resulted in the demise of a massive natural dye industry. So, it's necessary to classify the different types of dyes with the increase in the number of types and varying dyeing properties so that this would be a best way to understand the different types of dyes, their applicability, fastness and other properties. In this article, a source for the beginners is provided to understand different kind of the textile fabrics and their importance as well as their drawbacks, dyes and their various types, their interaction with the corresponding fabric, their color strength and color fastness properties.

Purpose The dyeing of cellulosic and proteinous fibers with natural and synthetic colorants usually needs large amounts of metal salts to promote the dyeing procedure. To get rid of the necessity to use metal salts, plasma treatment and subsequent attachment of chitosan biopolymer were considered as green processes for surface functionalization of wool and cotton. The purpose of this paper is to investigate the effect of oxygen plasma treatment and attachment of chitosan on the dyeability of wool and cotton fabrics using walnut and weld as model natural dyes, as well as C.I. reactive blue 50 and C.I. acid blue 92 as model synthetic dyes. Design/methodology/approach Wool and cotton fabrics were modified with oxygen plasma and coated with chitosan solution. The un-modified and modified samples were dyed with the above-mentioned dyes under constant conditions. The color strength, color coordinates and fastness properties of the dyed samples were determined and compared. Findings The results showed that oxygen plasma treatment could improve the dyeability and fastness properties of wool and cotton fibers when dyed with all of the above-mentioned dyes. Attachment of chitosan to the plasma-treated samples significantly improved the dyeability of wool and cotton fibers with walnut, acid and reactive dyes. The fastness properties of the dyed samples were enhanced by plasma treatment and chitosan coating. Originality/value This study uses plasma treatment as an environmentally friendly pre-treatment for attachment of chitosan on wool and cotton. This process improved the dyeing properties of both fibers. The use of metal salts in not needed for dyeing of wool and cotton according to the investigated process.

Dispersion Of Nanoparticles

The multifunctional textiles are interesting areas to be researched on. In this paper, the effect of the fiber nanocoating on the wrinkle recovery, air permeability and anti-Ultraviolet (UV) property of different woven fabrics using sol–gel method has been studied. The sol–gel method has various advantages over other methods. Along with these properties, no change in visual appearance has also been discussed in this paper. The dispersion of nanoparticles of titanium was obtained into silica sol. The characterization of nanocoating was done using Field emission scanning electron micrograph (FESEM) and Fourier transform infrared spectroscopy (FTIR) studies. The fabric wrinkle recovery properties, air permeability and anti-UV performance were analyzed using three different immersion timings into the nanosol. The results revealed that both wrinkle recovery properties and anti-UV performance have increased with respect to immersing time of the nanocoating although a slight decrease in air permeability and whiteness index of the fabric was also observed.
