An Eco-friendly Approach of Cotton Fabric Dyeing with Natural Dye Extracted from Bixa orellana Seeds Employing Different Metallic Mordants

Abstract

The aim of this project work is to study the application of Bixa orellana seed for dyeing of cotton knitted fabric. To satisfy the future demand for an eco-friendly as well as sustainable dyeing of cotton fabric numeric exploration had been performed in this work. Natural dye was extracted by normal water extraction method with caustic soda from raw seed of Bixa orellana. In this experiment commercially scoured-bleached 100% cotton knitted single jersey structure fabric with an areal density of 140 grams per square meter is used. Pre-mordanting action of cotton fabric samples were carried out using various metallic salts. Samples were dyed using by Glauber Salt + hot wash with Standard Soap, without Glauber Salt + hot wash, Glauber Salt + without hot wash and without Glauber Salt + without hot wash. Color strength of the dyed samples for different dyeing condition was assessed by means of K/S value. To intensify the color strength various mordanting agents were used. Effect of mordanting agents had evaluated by means of K/S value. Best color strength was yield for the samples dyed with Bixa orellana which were mordanted with CuSO 4. Impact of electrolyte on color strength had also investigated by means of K/S value. Color fastness of the selected dyed samples to water, washing, perspiration and rubbing were evaluated. Impact of mordanting agents, hot wash and electrolyte were intensively evaluated. In all cases mordanted samples with CuSO 4 exhibit best result. This result adumbrates developing a sustainable technology for a cabalistic utilization of Bixa orellana seed for coloration of cotton knitted fabric. The exquisite assessment of all tested properties of colored samples evolves this technology can be commercially implemented by considering few limitations.

Effect of different filters on the extraction of norbixin from Bixa orellana for synthetic fiber dyeing and development of a post-dyeing process for removal of the unfixed dye

“…The maximum value of 2.97 for the K/S remained within the expected range for this concentration of dye, as also reported by Bueno et al (2020) and Nakpathom et al (2019). The fastness scores for the cotton control fabric ranged from 1.5 to 2.0, indicating low fastness for the dyed fabric, values very close to those reported by Zaman et al (2018). This indicates that not all of the dye present in the fiber is effectively adhered to the fabric, requiring some additional process (washing) for its removal.…”

Dyeing process optimization of chitosan modified cotton dyed with Bixa orellana and Caesalpinia sappan

“…Compared to the results of Ohama's research which carried out dyeing of fabrics with natural dyes from sappan wood using FeSO4 metal mordant where the dyeing results produced a dark lavender color so as quite different from the original red color from sappan wood [5]. Meanwhile, in a study conducted by Zaman who dyed fabrics with natural dyes from kesumba seeds using various metal mordant (FeSO4, FeCl3, and CuSO4) the results of fabric coloring with a light brown final result [16].…”

PEMANFAATAN LARUTAN KAYU SECANG (Caesalpinia sappan L.) SEBAGAI COUNTERSTAIN PADA PENGECATAN GRAM Escherichia coli ATCC 25922

“…Hal ini karena etanol 96% memiliki tingkat kepolaran yang sama dengan brazilein. Adapun reaksi pewarnaan yang terjadi yaitu ikatan koordinasi antara alumunium dan gugus hidroksil peptidoglikan (tahap mordanting) dan kompleks koordinasi antara alumunium dan brazilein (tahap pewarnaan) (Zaman et al, 2018;StansFile, 2019).…”

“…Tingkat disosiasi mempengaruhi interaksi elektron kompleks alumunium-brazilein yang menyebabkan pergeseran batokromik. Adapun jenis reaksi pewarnaan yang terjadi yaitu kompleks koordinasi antara brazilein dan alumunium (tahap pembuatan larutan secang-mordan) dan ikatan koordinasi antara gugus hidroksil peptidoglikan dengan kompleks alumunium-brazilein (tahap pewarnaan) (Zaman et al, 2018).…”
