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.

T HE textile printing branch is becoming a widely-known technology for all fibers, textiles, and garments in the textile wet processing industries. Printing is a kind of coloring in which colors are applied to regions of the cloth rather than the entire fabric. In this study, we highlighted the use of eco-friendly natural dyes as a colorant material to decrease the environmental effect. Natural and synthetic dyes are substances of great interest since they play a significant part in our daily lives. A wide range of technical and industrial uses for dyeing or printing cloth, paper, leather, and other materials. Some of these colors are poisonous, carcinogenic, and can irritate the skin and eyes. Many harmful and allergenic synthetic colors are now prohibited. Many colors, while not yet prohibited, may not be safe.

Flax seeds gum is a heteropolysaccharide consist of neutral and acidic components that makes up approximately 8% of seed mass. Flaxseed gum was extracted from brown flaxseeds by the hot water extraction method. The rheological properties and the viscosity of the printing paste were measured. The effect of flaxseeds gum on the printing properties of different fabrics (natural and synthetic fabrics) was studied by measuring the color strength value (K/S) and related color parameters of the printed fabrics. Flaxseeds gums do have inherent problems associated with their use as a thickener including uncontrolled rates of hydration, drop-in viscosity on storage, and the possibility of microbial contamination to Improving the Performance of Flax Seed Gum. Two different metal oxides including titanium dioxide and zinc oxide in normal form and Nano form were prepared and characterized to Improving the Performance of Flax Seed Gum. The presence of metal oxides in both their natural and nanoforms on flaxseeds gum was found to significantly increase its resistance to bacteria and fungi as well as its life span and ability to resist rotting for the longest time feasible.
