A cost minimization process of heat and energy consumption for direct dyeing of cotton fabric coloration with triethanolamine

Abstract

A cost minimization concept of heat and energy consumption for direct dyeing process of cotton fabric coloration was experimented with triethanolamine instead of sodium carbonate in the dyebath of direct dyeing with low temperature at 30˚C, medium temperature at 60˚C and high temperature at 90˚C and compared with the conventional method of direct dyeing with high temperature at 90˚C where an acceptable range of increasing color strength (K/S) and color difference were observed for low temperature dyeing with triethanolamine (TEA method) comparing to the conventional dyeing process of high temperature with sodium carbonate (SC method). Considering heat and energy consumption in direct dyeing of cotton fabric coloration with triethanolamine method, the low temperature dyeing cost was minimized Rs. 2.24 comparing to high temperature sodium carbonate method dyeing cost.Citation: Hossain A, Samanta AK.

UV–Visible–NIR camouflage textiles with natural plant based natural dyes on natural fibre against woodland combat background for defence protection

“…Table 1, nine-NPND materials of woodland CB were collected, washed, dried, powdered/grinded and extracted by water medium. Three-dimensional method of textile coloration was applied to signify the feasibility of NPND-camouflage coloration of dyeing, coating and printing [21][22][23] . In terms of maximum and minimum reflection, standardized white and black background was used for comparison between target object, dyed-coated-printed textiles and selected woodland CB.…”

Результати Експериментальних Досліджень Повторного Використання Стічної Води В Поцесі Фарбування Бавовняних Тканин Прямими Барвниками

“…In order to minimise heat and energy consumption in the process of dyeing cotton fabrics with direct dyes, researchers from India [13] proposed the use of triethanolamine instead of sodium carbonate in a dye bath with low (30 °C), medium (60 °C) and high (90 °C) dyeing temperatures. As a result of the study, the dyed cotton fabric samples were compared with samples dyed using conventional technology.…”

Coloration of Polyamide-6, 6 Fabric with Carbon Black Nano Particle for Camouflage Textiles of Simultaneous Spectrum Probe in Visible and Near Infrared

“…Liquid phase dyeing is a common process for textile coloration but carbon black nano particle (CBNP) based technical formulation (FM) and camou age coloration is still a new approach [1][2][3][4][5][6] . Nitric acid (NA) modi ed CBNP has liquid phase oxidation property for enhancement of low re ection chromatic hue.…”
