Dyeing Behavior of the Cellulosic and Jute Fibers with Cationic Dyes: Process Development and Optimization Using Statistical Analysis

ABSTRACT

The aim of this study is to improve the dyeing behavior of cotton and jute fibers using natural product as surface modifying agents to the cationic dyes. Surface modifications have been performed on both cellulosic and jute used in this work by different types of chemical and natural products. Present study has been concerned with the evaluation of dyeing quality by controlling the percentage of dye bath exhaustion, the color yield (k/s) and the color fastness to light, washing and rubbing. In addition, optimization dyeing process was performed using a surface design with the help of Minitab 15 Software.

摘要

本研究旨在使用天然原料作为阳离子染料的表面改性剂来改善棉布和黄麻纤维的染色性能。在这项工作中，使用不同类型的化学产品和天然产品对纤维素和黄麻进行表面改性。本研究通过控制染浴吸尽的百分比、得色量(K/S）、耐光色牢度、洗涤和摩擦等条件，对染色质量进行评估。此外，本研究还借助 Minitab 15 软件通过表面设计执行优化染色工艺。
