Introduction to Sulfur Dyes Part 1
Introduction to Sulfur Dyes Sulfur dyes are complex heterocyclic molecules or mixtures formed by melting or boiling organic compounds containing amino or nitro groups with Na-polysulphide and Sulfur. Sulfur dyes are so called as they all contain Sulfur linkage within their molecules. Sulfur dyes are highly coloured, water insoluble compounds and have to be […]

Dyeing Jute yarn with Basic dye
Name of the Experiment: – Dyeing Jute yarn with Basic dye. Introduction: It is suitable for acrylic fibers (other fibers by mordanting). It reacts with acetic groups, or mordants a chemical which can react or complex with a chromophore to form an insoluble color in the fibre. It has good fastness properties on acrylic […]
Flat Knitting Technology
Flat Knitting Technology INTRODUCTION : The fabric which is produced by the machine is usually weft knitted fabric. Flat fabric will be produced. In the flat knitting machine needles are kept stationary and the cam will move along the width of the machine ( vice versa to circular knitting machine). It was first invented […]
