A Valuable Observation on Thickeners for Valuable Utilisation in the Printing of Different Textile Fabrics

Abstract

Thickeners are high molecular weight polymers used to impart viscosity and plasticity to the printing paste. Thickeners play an essential role in any printing process. Their main purpose is to hold dyestuffs, chemicals, and other printing auxiliaries to the fabrics during the method of printing. The goodness of the resulting print depends on the chemical and physical properties of the thickeners applied. The depth, the brightness of the colours, and particularly the sharpness and smoothness of the print are influenced or even determined by them.

An Overview of Printing Textile Techniques

“…[8][9][10][11][12] It is also the process of mixing a design concept, one or more colours, and a substrate (usually textiles) with a natural or synthetic thickener, while applying a technique to correctly apply the colours. [4,[13][14][15][16][17][18][19][20][21][22][23][24][25][26] The main objective of printing is to create colourful patterns with sharp borders on textile fabrics without any dye spilling beyond the design motif's borders. [27] Textile printing is defined as a regulated technique of colouring cloth in specific patterns or motifs by employing specialized printing techniques and machinery.…”

“…[28,29] it is also the process of creating a colour pattern or drawing on textile materials. [26,30] The colour is linked to the fibre in properly printed fibres to protect against washing and crocking. Localized dyeing is a term used to describe textile printing.…”

An Observation on the Wet Processes of Natural Fabrics

“…[1] Natural fibres are those that derived from a natural source which may be a vegetable or cellulosic source such as (cotton, jute, linen, hessian and ramie), or maybe an animal or protein source such as (Silk (Silkworm), wool (Sheep), cashmere (Goats), mohair (Goats), camel (Camel), angora (rabbit), and maybe ground and mineral sources such as (asbestos). [2][3][4][5]…”

“…Because of its cellulosic base, the fabrics which are made from it are susceptible to being infected with bacteria, fungus and mildew. [2][3][4][5] Chemical properties:-Cotton is highly resistant toalkalies. Strong acids and hot dilute acids will cause disintegration, all bleaches and most organic solvents.…”

“…It is a high-quality protein fibre that is obtained from the hair of the sheep and the best type of wool is obtained from Merino sheep. [2][3][4][5]8] Physical and chemical properties Physical properties: It has a creamy, brown or black colour. It has an average length of 1 -18 inches, with very weak strength properties, and it is also susceptible to shrinking.…”
