Preparation, Characterization, and Utilization of the Suspended-Keratin Based Binder in Pigment Printing of Man-Made Fibres

Objectives: Textile auxiliaries are commonly used in many textile wet processes including dyeing and printing. Herein, we criticize the different methods used in the synthesis and applications of binders in pigment printing of textile fabrics. Methods: Binders are used to hold the color onto the textile surface when applying pigments for textile printing. Most of the binders used in textile printing are based on the addition of polymerization systems. When a binder is applied with pigment to textile, it forms a three-dimensional network, this is due to the binders being considered as a film-forming from long-chain macromolecules. Findings: The choice of binders depends on the final fastness properties as well as the cost requirements of the process. Many different binders were developed for other purposes, resulting finally in the use of emulsions. This led to an increase in the use of pigments in textile printing and the binder has become one of the basic matters utilized in the printing paste. Biopolymers would be appropriate elements in the production of eco0frienddly binders suitable for benign printing of textile substrates. Novelty: This review presents some negotiable points regarding the binder's functions together with its chemistry, synthesis as well as its mode of action, and its effect on the extent of fixation of the pigment on the printed textile surface.

“…These groups include the carboxylic, amino, hydroxyl, thiol, and amide groups, which vary in their polarity. Regenerated keratin from wool and feather was successfully used in enhancing the dyeability of wool fabric with acid and reactive dyes [88], and in pigment printing paste prepared for printing of polyester and polyester cotton blends [89,90]. It was also used in hydrophilization of saponified polyester fabric [91] and in imparting bactericidal effect to viscose fabric [92].…”

Ever since the Stone Age, humans have preferred natural products and materials for better health and comfortability. Wool and natural silk have been used in the textile clothing thousands of years ago. The performance and appearance attributes of wool and silk make them superior for many applications. On the other hand, the textile industries are technically, economically, socially, and environmentally related to some of the sustainable development goals (SDGs) of the United Nations Agenda 2030. For instance, the item number 12 in the SDGs aims to ensure sustainable consumption and production pattern. This necessitates proper utilization of all natural products as well as recycling and utilization of any waste thereof.This article review deals with retrieval of wastes or by-products during wet processing of proteinic fibres; namely wool and silk. Different ways of proper utilization of the retrieved materials will be proposed. Specifically, this review article will focus mainly on three main by-products; namely keratinous materials, wool wax, and sericin. State of the art and future prospects for the utilization of these materials in the production of textile auxiliaries; Viz. softeners, binders, and flame-retardants, were discussed.

“…-It must have physical and chemical features such as viscosity, desired flow properties, ability to wet and adhere to the internal surface of the print fabrics.\It should be consistent with the other printing paste components 16 , 17 , 18 -The thickener should dry properly to prevent color from spreading -It should have good adhesion to the fibers to avoid loss of colorant during mechanical handling.…”

A thickening agent that's particularly suitable for printing pastes is, water-insoluble, water-swellable, or water-swollen polymer made by reverse phase polymerization of a mix of water-soluble. Where there are three basic styles of thickeners: a) polysaccharide thickener, b) synthetic thickener, c) emulsion thickener, all of them may be used as a thickening agent alone or a combination of them. Synthetic products, particularly, have come under severe criticism for his or her high environmental pollution at the manufacturing stages and applications. However, auxiliaries derived from natural resources, especially from plants, are considered biodegradable, non-toxic, and non-allergenic than their synthetic counterparts. The most goal of this review is to administer an summary of educational study within the field of thickening agents supported thickener and also the potential application in textile printing.
