A reproducing guideline for every Ready Made Shade (RMS) has been mentioned in this chapter.

Color Research & Application, 2008

Colors from naturally dyed fabrics recently have attracted both consumers and manufacturers in fashion markets. Even though color attributes of the fabrics have been partially observed in some literature, a data base of colors for natural colorants in fabrics needs to be established and the colors to be characterized according to systematic color notations and tones in order to relate the traditional natural colors to contemporary color communication systems. Therefore, a study was performed to investigate color characteristics for a given large set of natural colorants-dyed fabrics based on the Munsell color notations, to analyze their tones with relation to the notation such as hue, value, and chroma, and finally to identify the effects of mordanting, an important coloring auxiliary, on the colorimetric properties of the fabrics. As a result, the dominant hue for a total of 350 naturally dyed fabrics was yellowish families followed by reddish and purplish ones in the Munsell notation owing to the use of leaves and plant as usual natural dyestuff, which confirms the limit of color hues of the fabrics. Color value for most of naturally dyed fabrics was generally higher whereas the chroma was lower, which means that most of colors for naturally dyed fabrics tended to be bright and weak shaded. Grayish, light grayish, and soft tones were the main tones of natural colorant-dyed fabrics. All of hue, value, and chroma were found as being influenced by mordanting in that more particularly; iron mordanting was likely to cause the decrease of both value and chroma for most of naturally dyed fabrics. These results could provide a systematic color data for naturally dyed fashion fabrics and suggest a future direction of color development for them.

Current Trends in Fashion Technology & Textile Engineering

Natural dyes have been used since long back in various areas such as textiles, craftwork, food colouring and also as medicine. This work was based on expansion of the colour shade that can be obtained from natural dyes for use by the small scale users. The natural dye was extracted from three naturally available plants locally in Zimbabwe using the cold extraction under gravity method. An alcohol was used to extract the dye using a vacuum pump and left to dry. The extracted dye was then used to dye fabric strips using different metals as mordants. From the colour charts generated from the various dyeings it was shown that the shades can be extended for certain plants and in some cases they are not easy to expand. Application of the metal mordants at different concentrations was also found to have an effect on the hue of the dyed fabric strips. The results show that the natural dye from the Mukwa (Pterocarpus anglonesis) gave a wider range of shades as compared to the other two dyes.

This paper highlights the basic dyeing terminologies which are often used in dyeing process. The central theme of this paper is to provide authentic knowledge to textile students and practical dyers in complete scientific manner because most of the students & dyeing related people have misunderstanding regarding basic dyeing terminologies. Some explanations of basic terms are also discussed in this paper.

International Wool Secretariat Technical Centre llkley Yorkshire A relationship has been established between the dyeing properties of fibre-reactive dyes and the spectral reflectance properties of the colours produced on machine-washable wool. The information gained in routine dye calibration for instrumental colour-prediction systems may be used by the practical dyer for dye selection. The spectral reflectance properties of the resultant dyeings are explained in terms of the diffusion, fixation and level-dyeing properties of specific fibre-reactive dyes applied to wool by exhaust and pad-dyeing processes.

The textile market is increasing rapidly and becoming more and more competitive day by day. Customers are getting very much conscious about what they are buying and demanding more and more with respect to quality. It is creating challenge for the manufacturer to gain profit by continuing production through implementing the usual processes and they are forced to ensure various production parameters and settings in the machines for achieving much more effective, efficient and quality product as well as reducing cost. Therefore, it is very much important to know about the various dyeing processes along with gradual improvement. This research includes information that presents a detailed description of the standard & latest working procedure in wet processing. It is tried to highlight the main aspects, parameters & descriptions of important dyeing sections especially Woven dyeing section which depicts a comparison based on the information given here for getting an idea on most common dyeing processes and which are better to use in this competitive market. Then color fastness to wash, color fastness to dry & wet rub were tested. Change in K/S, lightness DE and overall color difference DE were observed & analyzed.

Expanding ecological cognizance all through the globe has constrained scientists and industrialists to become accustomed to more sustainable techniques. Wet processing technology in textiles devours heaps of water, synthetic compounds, colorants, and assisting chemicals which create a high measure of discharge load and eco-standard of conclusive product. Different methodologies have been proposed by numerous specialists and rehearsed effectively in controlling the said issues of textile wet processing such as the utilization of biotechnology and dyeing with natural colorants, pigments are regarded as one of the significant perspectives in the mentioned territories. In the past, natural dyes were the main wellsprings for coloring textiles. With the creation of synthetic colorants in 1856 by W H Perkin from coal tar, the utilization of natural dyes dropped immensely. Regardless of some basic restrictions related to dyeing of textile fibers with natural dyes, synthetic dyes have been broadly embraced in numerous applications because of its availability and easy application methods. Despite the high market share of the overall industry, the creation and application techniques for synthetic dyes have some ecological limitations, for example, causing water pollution and hazardous to humans. Besides, synthetic dyes are relying upon hydrocarbons, which is a non-inexhaustible wellspring of chemicals for the synthetic dyeing method. Nowadays, the capability of natural dye utilization consistently rises because of their particular favorable circumstances like nonharmful, noncancer-causing, renewable source, and ecologically amicable. 4.2 Eco-friendly pretreatment of textiles Cellulose fibers, regardless of whether they are extracted from nature or chemically modified, need some type of treatment to make them reasonable for coloring or finishing process. This treatment, which evacuates common or included contaminations, is known as pretreatment. It tends to be done on fibers, yarns, or fabrics. For cotton and other natural fibers pretreatment process includes singeing, desizing, scouring, mercerization, and bleaching. These pretreatment processes consume a large amount of water, chemicals, and electricity (Table 4.1). The existence of colorants in water is particularly unsafe since a large portion of these synthetic substances are entirely stable toward sunlight based radiation, humidity, microbial assaults, and agents which cause oxidation [1]. To wipe out the existence of dyes in both natural water reservoirs and industrial wastewater plants, different procedures were followed, for instance, using chemicals and biological substances, ion exchange process, membrane
