Jute-cotton and jute-wool union fabrics have been printed with colorant extracted from Rheum emodi with guar gum and albumin as thickening agents and aluminium sulphate, copper sulphate, and ferrous sulphate as mordants. Printing with Rheum emodi colorant with different mordants resulted in different shades ranging from yellowish brown, deep brown, reddish brown, and gray shades to olive black. The K/S value showed that mordants, namely, CuSO4 and FeSO4, exhibited high colour absorption regardless of the nature of material used. All the printed samples have good to excellent wash, rubbing and light fastness properties regardless of the nature of materials, mordants, and thickeners used. Guar gum is closely at par with albumin as a thickening agent and considering the cost and availability of raw material, guar gum is the better choice for the textile industry.

Purpose The present study aims to focus on the feasibility of using an aqueous extract from the fruit shell of Camellia oleifera Abel as a source of natural colourant in printing-paste preparation for pigment printing of cotton fabric. The effects of pre- and post-mordanting with three common metallic mordants, that is AlK(SO4)2, CuSO4 and FeSO4 on colour yield and colour fastness properties are also investigated. Design/methodology/approach The printing paste was prepared by mixing the concentrated Camellia oleifera Abel fruit shell extract solution with commercially available synthetic thickener and binder. The fabric sample was printed with the prepared printing paste using a flat-screen printing technique. To determine the effects of pre- and post-mordanting, AlK(SO4)2, CuSO4 and FeSO4 mordant aqueous solutions with various concentrations were applied using the pad-dry technique. Comparisons between printing with and without mordants were evaluated in terms of colour strength (K/S values) and colour fastness to washing, light, crocking and perspiration. Findings Without the mordants, the printed fabric had a yellowish brown shade with acceptable colour fastness properties, that is fair to good wash fastness, moderate light fastness, good to very good crocking fastness and fair to good perspiration fastness. The use of mordants, especially CuSO4 and FeSO4, not only enhanced colour strength but also imparted different colours to the fabric. Compared to the unmordanted fabrics, colour fastness properties were mostly comparable or improved in the mordanted fabrics depending on the type and concentration of mordants. Research limitations/implications Although in the case of CuSO4 the light fastness was increased to a good to very good level, it is recommended that the final print be produced with a concentration of less than 0.125 gL−1 to yield the print with the residual amount of Cu metal under the limit, that is less than 50 ppm as regulated by the Oeko-Tex® standard. Practical implications The obtained prints from Camellia oleifera Abel fruit shell extract provided shades with satisfactory colour fastness to washing, light, crocking and perspiration. The extract from Camellia oleifera Abel fruit shell has the potential to be used as an alternative to synthetic dye in the textile industry. Originality/value The use of Camellia oleifera Abel fruit shells, which are considered as abundant byproducts of tea seed oil production, as natural colouring agents for pigment printing of cotton fabric has been reported for the first time. It will minimise the environmental impact of this waste and create more valuable textile products.

The Impact

Natural dyestuff has reverted its position in the colouration of textile substrates due to rising concerns of consumers and buyers, particularly about environmental impacts and health issues. Eucalyptus leaves were selected in this study as a source of natural dye along with some of the most generally used mordants to observe the impact of dyeing on jute fabric while trying to keep the dyeing parameters at a minimum level. Dyes were extracted from eucalyptus leaves by boiling in water. Then, the fabric was pre-mordanted using different synthetic mordanting agents, such as alum, potassium dichromate, copper sulphate and ferrous sulphate, which are generally used to substantively enhance the dyestuff on textile fabrics and to improve the fastness properties. Synthetic mordant was used here instead of natural mordant due to the better dyeing compatibility of jute fabric with eucalyptus leaves, since natural mordant has little effect on jute fabric during the process of dyeing. Another aim of this research is to curb the time and energy consumption of the jute dyeing process and so the dyeing is carried out at 75 °C for about 30 minutes. Various types of evaluations were conducted through visual assessment, checking the colour-coordinate values and colour strength values. While colour fastness properties were evaluated by different fastness testing, such as colour fastness to water, washing, rubbing and perspiration. This dyeing process yields a colour range from yellowish to brown with the variation of mordants applied on the fabric. In addition to that, colour co-ordinate and colour strength values ensure better results of dyed fabrics pretreated with ferrous sulphate. Jute fabric dyed with only extracted eucalyptus solution provided satisfactory results in all colour fastness tests, while fabric treated with different mordants showed variations in fastness ratings, and fabric treated with ferrous sulphate and copper sulphate had slightly better fastness ratings.

The present study is based on the process development for colouring of silk yarns with Dhavdi flowers using selected mordants to study its effects on colour fastness properties and optimization of different extraction conditions, duration and concentration for better dye and its shades. The results revealed that aqueous medium was suitable for extraction of dye from pink petals of Dhavdi flowers for one hour. The shades of midbuff, sand stone ,coffee and olive green brown were obtained by taking 4 g dried powder of dhavdi dye for dyeing 1 gram of silk material for 45 minutes. All the four mordants were found suitable for application on silk, 10 % of alum, 3 % of chrome, 2 % of copper sulphate and 3% ferrous sulphate were found to produce best shades on silk material. Post mordanting had resulted in darker shades in all the mordant. Simultaneous mordanting method was found best in case of chrome mordant. Excellent to outstanding fastness to sunlight was found in all mordanted samples. There was absolutely no staining in washed samples. Colour change was not found in the samples subjected to crocking in both dry and wet conditions except in case of ferrous mordanted samples,. The colour was stable as shown by their higher resistance towards acidic and alkaline perspiration. Hence, the dye obtained from Dhavdi flowers proved to be extremely good and can be recommended for dyeing silk fabric.

Pulp Production

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.
