A Study of Sedge (Cyperaceae) Dyeing with Natural Indigo Dye

چکیده
The aim of the study was to investigate dyeing conditions that are appropriate for sedge fi bers with natural indigo dye as they usually do not absorb water. conditioning is therefore essential in order improve their water and color absorption properties. process included soaking 1, 2, 3, 4, 5% sodium hydroxide (NaOH) ratio solution (a liquor ratio) 50:1 24 hours. conditioned were analysed functional group changes by Fourier transform infrared (FTIR) spectroscopy examined using glucose reducing agent instead dithionite (Na2S2O4). Time temperature variations also used identify suitable conditions. ndings revealed a most effective when soaked 20 minutes at 40 °C. dyed strength (K/S) fastness. It can be concluded NaOH level concentration condition dyeing.

Sustainable Dyeing of Denim Using Indigo Dye Recovered with Polyvinylidene Difluoride Ultrafiltration Membranes
Indigo is one of the most consumed dyes in the textile sector, as it is widely used for the dyeing of denim clothes. About 15% of indigo used in the dyeing process is discharged to the wastewater treatment plants or sometimes into rivers, in countries where regulations are not strictly applied. In this work, real effluents that contained indigo dye were treated by means of 4 different ultrafilt...
متن کاملComparison of dyeing of polyester fibers with natural dye and bio-mordant
In this study, dyeing of two regenerated polyester fibers, poly-trimethylene terephthalate (PTT) and poly-lactic acid (PLA), with natural dyes were compared with that of poly-ethylene terephthalate (PET) fiber. Lac was used as the primary natural colorant while Catechu was chosen as a natural color that can also act as a biomordant. The effects of temperature, initial pH of dye bath and dyeing ...
