Objects of Singeing | Gas Flame Singeing Machine

Definition of Singeing Singeing is carried out rarely on knitted fabrics and frequently on yarns and woven fabrics. Instead of the traditional singeing process, it is possible to apply an enzymatic treatment (for cotton and lyocell fabrics), for example with cellulose, which uses chemical agents to corrode the fibre surface and remove the fuzz from the fabric.[…]

An Overview of Sulphur Dye [A to Z]

Among the various fashion articles, denim is the fashion icon. For ages, denim has held its waist. Denim fabrics are made of different colors and different styles. Blue, black, or any other color is basically made with sulphur. In this article, we will discuss the critical points of sulphur dye. Significance/Properties of Sulphur Dyes Note:[…]

An Overview of Azo Dyes

Introduction The dyes containing azo groups – N = N – are called Azoic Dye. These are not ready made dyes but are produced by reaction of two components – Diazocomponent or Base/Salt and coupling component (Napthol). Azoic dye also named as Napthol, Branthol, Magic and Ice color. Dye formation in fiber occurs on the basis of[…]

The Textile Chemicals are as follows: Wetting Agent The chemical which is used for[…]

Notes on Disperse Dye

The textile industries dye polyester yarn or fabric use disperse dye for its versatile color. The dyes are hydrophobic, so the dispersing agent is required to spread the dye onto the yarn or fabric surface. Here high temperature and pressure are also required to fix the dye particles into the fibre molecules. The dyes hold[…]

Notes on Reactive Dye

Reactive dyes are special coloring agents that textile industries use for dyeing fibre, yarn, fabrics, and garments. These dyes are popular in the textile industry because they make colors that fix well and don’t fade quickly. Unlike other dyes that fix on the fabric’s surface, reactive dyes combine with the fabric’s molecules through a chemical[…]

Why Reactive Dye is So Called?

Definition of Reactive Dye Reactive dyes are a class of colored compounds that chemically bind to fibers like cotton, rayon, or linen to impart color resistance to washing and fading. To apply reactive dyes properly, we need a process with controlled conditions. Usually, they are used in an alkaline bath with sodium carbonate or sodium[…]
