Extraction of natural dye from the leaves of Wild Himalayan pear (Pyruspashia) and optimization of the dyeing parameters using  Box-Behnken Design (RSM)

Today universe is inclined towards eco-friendly and sustainable products. Its interest is shifting from synthetic products to natural once. The present study involves the optimization of extraction pH of natural dye and optimization of dyeing parameters for dyeing of silk fabric using response surface methodology (RSM). The extraction of dye from the leaves of Pyrus pashia (Wild Himalayan pear) was carried out in acidic, neutral and alkaline pH. The neutral pH exhibited the highest colour strength than alkaline and acidic pH. Box-Behnken Design (RSM) was used for optimization of dyeing variables. The effect of independent variables i.e. dye material concentration, dyeing time and temperature were assessed on dependent variable i.e colour strength of the dyed silk fabric sample. The optimized dyeing variables obtained for application of P. pashia leaf dye on silk fabric were 5% (w/v) dye material concentration, 70°C dyeing temperature and 45 minutes dyeing time. It not only creates a source for a natural dye but can also lead to creating employment amongst the rural people. P. pashia has a potential to colour silk fabric and can be used to dye other natural fibres such as cotton and wool which can be a step towards sustainable development. dyeing with its leaf extract can be helpful in promoting eco-friendly processing of textiles.

The dyeing and fastness properties of silk fabric dyed with natural dye extraction from the bark of Garcinia Dulcis (Roxb.) Kurz by the pad-batch process was studied. The effect of dyes at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Garcinia Dulcis (Roxb.) Kurz bark extract showed a pale yellow shade, while those dyed with alum and stannous chloride bright yellow and light yellow colour, respectively. Silk substrates dyed with CuSO4 gave a yellowish green colour, while those dyed with FeSO4 had a dark brown colour. The fastness properties showed fair to good rating, whereas the colour fastness to perspiration was at a poor level.

Purpose Dyeing of silk fabric was studied to increase dye uptake using eco-friendly glycerine based eutectic solvent (GES), which acts as a swelling agent. Design/methodology/approach The swelling behaviour of silk fabric in GES was analyzed using three-dimensional laser scanning microscope. Dyeing parameters such as time, temperature and GES concentration were optimized using design of experiments. Findings In total, 5.34 F-value and 0.0014 p-value of ANOVA represent that the model is significant. An optimized GES assisted dyeing was carried out with two different classes of dyes such as Acid Blue 281 and Acid Red 151 and further compared with that of conventional aqueous dyeing method. Originality/value At 70°C, silk fabric achieves desired colour strength after 35 min of dyeing (10 min lesser than conventional) using GES assisted dyeing method. % Dye exhaustion of GES assisted dye bath was carried out and found to be very good. Fastness properties such as washing, light and rubbing fastness of conventional and GES assisted dyed silk fabric showed comparable results.

Silk Fabrics

Natural dye extracted from the longan leaves was applied to a silk fabric by an exhaustion dyeing process. The dyeing was conducted with and without metallic salt mordants using pre-mordanting. It was observed that with an increase in the dye concentration, the ultraviolet (UV) protection factor (UPF) values ranged between good and very good for the silk fabric. In addition, a darker color, such as that provided by a CuSO4 and FeSO4 mordant, gave better protection because of higher UV absorption. The results confirmed that natural dyes from longan leaf extract with metal mordants have potential applications in fabric dyeing and in producing UV-protective silk fabrics.

Silk Dyeing

The resurgence of natural dyes is gaining fame in textile industry due to eco-friendly nature. The present study was done to investigate the Coconut coir as natural dye (tannin) for silk dyeing under Microwave (MW) treatment following the optimization of experimental parameters. Isolation of colorant was carried out in aqueous, acidic and organic media (methanol) under influence of MW treatment up to 6 minutes. Dyeing of silk was carried out having irradiated and unirradiated extracts. Good colour strength was achieved by dyeing unirradiated silk using methanolic extract under MW treatment for 4 minutes at 75°C. The optimal dyeing was achieved at 75 minutes at pH 8 while keeping fabric liquor ratio 1:25 having 5 g/100 ml table salt as an electrolyte. For development of shades, salts of Al and Fe and Tannic acid were used as pre- and post-chemical mordants and Acacia, Pomegranate, Turmeric and Henna as pre- and post-biomordents. Acacia (6%) as pre-bio mordant and Turmeric (6%) as post-bio mordant considerably improved the colour strength at optimal conditions utilizing irradiated extract of coconut coir (tannin) and un-irradiated silk under MW treatment at 4 minutes. ISO-standard shows good colour fastness and colour strength at optimal conditions using Acacia and Turmeric as bio-mordents. This research work gives information about tannin extracted from Coconut coir has great potential to dye silk fabric to produce reddish-brown colour under the influence of microwave treatment. FTIR spectral study revealed chemical changes in the silk fabric treated with microwave radiations.

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.

Natural dye solution from longan leaves was applied to the simultaneous dyeing of silk fabric and using alum, copper sulfate, ferrous sulfate and stannous chloride as a mordanting agents. The dyeing properties and effects of simultaneous-mordanting on the hue, colour strength and colour value were revealed. The results show that The K/S values increased with an increase of metal mordant concentration. The mordant activity sequence was CuSO4> FeSO4> AlK(SO4)2 > SnCl2. The obtained colour values show that silk fabrics dyed without mordant exhibited dark brown colour, while those mordanted with aluminum potassium sulfate (alum), stannous chloride and copper sulfate showed a variety of medium to dark brown shades. With ferrous sulfate, the colour shade was darker and duller. The colour fastness results showed good to very good level.
