Young coconut coir (Cocos nucifera Linn.) waste has the potential to be processed into a useful product, namely as a source of natural dyes, especially in cotton fabrics. Processing is carried out through a maceration process for 72 hours using 96% ethanol as solvent. The obtained extract was applied on cotton cloth with various concentrations of the extract solution, 5, 10, 15, 20, and 25%, and various soaking times of the fabric in the extract for 60, 90, 120, 150, and 180 minutes. The extract was analyzed using Uv-Vis Spekctrofotometer it showed that the ethanol extract or dye that is absorbed into the cotton fabric with various concentrations is 3.43, 4.82, 6.61, 7.79, and 9.03%, respectively. The various soaking times show that on the other hand that the extract absorbed into the fabric was successfully obtained around 7.75, 9.64, 10.81, 11.65, and 12.04%. The results show that the concentration of the extract solution and the increasing length of soaking time can increase the percentage of extract or dye absorbed in cotton fabrics

Coconut husk is considered waste and its fibers can be used as a source of natural dyes for textiles. The objective of this research is to obtain natural dyes from old coconut (Cocos nucifera) husk waste fibers through the extraction process. Brown color was produced in the liquid-liquid extraction method. The brown color natural dyes were then used to dye cotton cloth. Three different binding agents were used during the fixation process, i.e. tunjung, naphtol salt, and alum. The coloring results of the natural dye on the cotton cloth were as follow: with alum binding agent the resulting color was light brown (cream), whereas tunjung binding agent produced a greenish brown color, and using napthol salt binding agent produced yellow color. The colored cotton cloths were tested for their color fastness properties against rubbing, soap washing, and sunlight exposure. The measurement scale used was grey scales, which was used to evaluate the color change (color fading) and color staining (color transfer) during color fastness testing. In general, based on the results, the colored cotton cloth using alum as binding agent showed better color fastness properties against rubbing, soap washing, and sunlight exposure compared to the ones using tunjung and naphtol salt binding agents.

Plants, which are the biggest source of natural dyes, have been used as coloring agents since the beginning of humanity. In this study, the usability of eastern groundsel, which is thought to be an alternative for the textile dyeing industry, especially for sustainable and renewable textile production, was investigated. Dyeing processes were performed with different concentrations of dyeing baths of natural dye which is extracted from the crowns of the eastern groundsel (Senecio vernalis) plant. After dyeing, dye flotte concentrations were determined using UV-visible spectrophotometer and the percent uptake of natural dye on cotton fabric was measured Spectrophotometric color analysis of the fabrics was performed and fastnesses of the samples were evaluated. It was found that the coloration of cotton fabrics with the use of Eastern groundsel (Senecio vernalis) in suitable dyeing application conditions could be managed with almost sufficient fastnesses.

PurposeCotton being an anionic fiber can be dyed with direct, reactive, vat and sulfur dyes but cannot be dyed with acid dyes due to their chemical differences. But there are certain advantages of acid dyes like acid dyeing is the simplest method than the other classes of dyes; and it offers various intense and bright shades. So, the purpose of this paper is to focus on acid dyeing of cotton fabric after its chemical modification.Design/methodology/approachSuch modification of cotton fabric has been achieved using poly(amido)amine dendrimer (PAMAM) treatment. The current work is based on the synthesis of a full-generation PAMAM dendrimer (G0) and its application onto the cotton fabric for modifying the cotton substrate by the exhaust and padding method.FindingsThe treatment of the dendrimer on cotton fabric has been analyzed by Fourier transform infrared spectroscopy and scanning electron microscopy. The dyeing results in terms of color strength of the treated cotton fabrics are compared with those of conventional acid dyed silk fabric. The fastness assessments such as wash, light and rubbing fastnesses after dyeing of treated cotton fabrics are also performed and found to be satisfactory.Originality/valueThis paper can be used in the application of synthesized poly(amido)amine dendrimer in acid dyeing of cotton.

Colour Fastness

Natural dyes can make less environmental problems associated with manufactured colouring agents and textile dyeing. But, the natural dyes fixing process was used chemicals called mordant. The most of times mordants were used metallic salts and metal salts mordants were not environmentally friendly. Therefore, remove the disadvantage associated with natural colorants and the use of nanoparticles. In this research, cotton fabric was treated with the nanoparticle of cellulose nanocrystals (CNCs) as mordant. The cellulose nanocrystals extraction process was done by using Whatman filter paper. The cellulose nanocrystals obtained will be further analyzed and characterized by using selected tools such as Particle size analysis and Fourier-transform infrared (FTIR) spectroscopy. The cotton fabrics mordanting processes were done by two types of pre-mordanting and post-mordanting methods. The three natural ingredients of Mangifera indica (Mango) leaves, Tectona grandis (Teak) leaves and Lannea coromandelica (Indian ash tree) leaves were used to extract the natural dyes using with aqueous extraction method. The extracts from dyeing processes were carried out after and before mordanting processes. The dyed sample from colour fastness to light, washing, and crocking were assessed according to standard methods. The cellulose nanocrystals gave very good colour fastness to light, wash, and rubbing when dyed with all three dye extractions. In the present study, innovative mordant of cellulose nanocrystals and natural dyeing with three natural dye extractions have been shown to give good dyeing results with cotton fabric.

Silk and cotton fabrics were dyed using the extract from blackcurrants, and the properties of the dyed fabrics were investigated. The natural dyes present in the blackcurrants were identified as four types of anthocyanins, i.e. delphinidin-3-glucoside, delphinidin-3-rutinoside, cyanidin-3-glucoside, and cyanidin-3-rutinoside. The colors of the fabrics dyed with and without five types of mordants, including Mg2+, Ca2+, Al3+, Fe3+, and Cu2+, were measured and expressed according to the CIELAB color system, Δ E* value, and K/ S value. The affinity of the extracted dye for the silk fabric was higher compared with that for the cotton fabric. The crystallinity of silk was lower than that of cotton. The fabrics dyed with blackcurrants had UV shielding ability, especially at 330–400 nm, and antibacterial properties. Although color fastness to light and washing (color change) was not sufficient, treatment with Mg2+, Fe3+, and Cu2+ mordants could enhance the color fastness.

Abstract A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut (Cocos nucifera L.) coir dust (CD) as growing media components for greenhouse production of Dracaena marginata Bak. and Spathiphyllum Schott ‘Petite’. Three soilless foliage plant growing mixes (Cornell, Hybrid, University of Florida #2 [UF-2]) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (% by vol): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2 = 50 CD or SP: 50 PB. Dracaena root growth was not affected by treatments but there were significant mix × media component interactions that affected plant top growth parameters. In general, the growth and quality of D. marginata were reduced by using CD in Cornell, had no effect in Hybrid, and increased in UF-2. S. ‘Petite’ grew equally well in all growing mixes regardless of whether CD or SP was used; however, plants grew more in Cornell and Hybrid than in UF-2. S. ‘Petite’ roots, which were infested with Cylindrocladium spathiphylli, had higher grades when grown in CD than when the media contained SP.
