“…Organoclay has no effect on colour fastness to light properties of PLA fiber. Colour fastness to washing ratings for staining of adjacent fabrics in case of curcumin are good to very good (4-5) and those for change in colour are also good to very good (4)(5). It should be noted that the improvement in rate of change in colour is observed at higher chitosan concentration in organoclay.…”

“…Recently, the textile finishing industry has tended to restrict the use of such synthetic dyes for human health and environmental reasons. As a result, the use of natural dye has increased due to its biodegradability, non-toxicity, its sources not posing risk to human health or waste water as contaminant [3][4][5]. Curcumin is the most popular of the bright yellow-orange natural dyes.…”

The aims of the present study were to use organoclay to improve the property of poly(lactic acid) (PLA) fiber in the dyeing process. Chitosans were used to modify montmorillonite (MMT) to produce organoclay. Poly(lactic acid) was melt-mixed with oganoclay using a twin-screw extruder to achieve a PLA/organoclay nanocomposite. The nanocomposite fiber was then prepared using single-screw extruder. The effects of organoclay on the structure, thermal and dyeing properties of the nanocomposite were also investigated. The results of dyeing show that the nanocomposite fiber was dyeable with natural dye extracted from curcumin. The colour strength was found to be dependent on the amounts of chitosan in the organoclay. The fastness properties such as wash fastness and light fastness were found to be similar to that in traditional fibers. Other properties such as thermal stability were also reported. This study demonstrates that poly(lactic acid) can exhibit natural dyeability through its preparation in nanocomposite form.

“…The inoculums were a nutrient broth culture containing 1.0 9 10 5 colony forming units (CFU)/mL of bacteria. For test swatches to be in contact with the bacteria for 24 h, 100 mL of sterilized distilled water was poured into the vessel and was shaken in a bacterial suspension and the reduction in bacterial activity in standard time was measured [11,12]. The efficiency of the antimicrobial treatment was determined by comparing the reduction in bacterial concentration of the treated sample with that of the control sample expressed as a percentage reduction in standard time.…”

Since the last decade, the application of natural dyes on textile material has been gaining popularity all over the world, possibly because of the increasing awareness of issues concerning the environment, ecology and pollution control. The present paper investigates extraction of natural dye from leaves of the plant Vitex negundo, which is an abundant, cheap, and readily available agricultural by-product. Water extracts from V. negundo was used to dye silk fabrics. Optimum extraction conditions included pH 9, duration 120 min, and temperature 90°C. Optimum dyeing conditions included dyeing pH 5 and duration of 60 min. Potash alum, tannic and tartaric acid were used as mordants, all of which are benign to human health and the environment. Color strength and color coordinates in terms of L*, a*, b*, C, and h were examined. A range of shades were obtained when fabrics were dyed with different mordants and mordanting techniques. The extracted dye was tested for some of the eco-parameters using atomic absorption spectrophotometry and GC/MS. The test results were compared with set standards to determine the eco-friendliness of natural dye. Their concentrations were found to be lower than the stipulated limits. Dyed samples were tested for antimicrobial activity against gram-positive and gram-negative bacteria. The dyed silk fabrics showed acceptable fastness properties and were also found to possess antibacterial activity. It can be concluded that the abundantly available agricultural byproduct V. negundo has great potential to be effectively utilized as a natural dye for silk.

“…Recently, the textile finishing industry tends to restrict the use of such synthetic dyestuffs and pigments in order for human health and environmental purposes. As a result, the use of natural dye has begun to increase for their better properties as being biodegradable, non-toxic, origination no problem to human health and waste water contaminant [3][4][5]. Natural dyes are environmental friendly, low toxic and less allergenic.…”
