The Process of Making Fiber Reactive Dyeing

 

Fiber-reactive dyes are a boon for the fabric manufacturers for their favorable properties, such as ease of access, easy use, affordability, and powerful impact.

In addition, the various properties of reactive dyes, including water solubility, availability of multiple shades, bright color shades, and light fastness, make it a very commonly used type of dye for textiles.

What Is Fiber Reactive Dying?

Fiber reactive dying is the process of imparting the desired color and shade to all the fabric made up of cellulose.

The dye reacts with the fabric to form a covalent bond in the fiber reactive dyeing process. This bond is very strong, giving permanent colors to the material.

The fiber-reactive dyes attach permanently to the fabric. The chromophore in the molecules absorbs some spectrum and reflects the others.

The dying process is slow and influenced by several factors, such as temperature and pH level. For instance, the higher temperature and pH speed up the reaction.

What Fabrics Can I Use a Reactive Dyeing Process On?

There are many ways of dyeing fabric. It can be bottle dyeing, tub-style, ice dyeing, stamping, or batik. The tub dyeing method comes out to be the most common as it is easy and can be taken up as a DIY project.

It is ubiquitous to find people and entrepreneurs scaling up their business with the tie-dyeing process. Let us get into the details of the process.

1. Prepare the fabric

The fabric cannot be just taken and immersed into the dye. There is a preparatory process for both things. As the preparation, select the proper cloth. Try to use the cloth with lighter shades than the dye for the appropriate effect.

Wash the cloth in hot water with some washing soda to remove dirt, dust, and grease from it. These foreign particles can act as an obstacle in an adequate reaction. The water temperature in which the cloth is to be heated should be taken care of.

Cloths such as silk should be treated in mildly heated water. Next, treat the fabric with soda ash. Soda ash is added to hot water, and the fabric is dipped.

2. Dye preparation

The next step in fiber reactive dyes processing is deciding which dyeing method is to be used. In many methods such as tub dyeing, dip dyeing, tie-dyeing, hand painting, and submersion dyeing, the dye is dissolved with water to make it liquid before applying it to the fabric.

On the other hand, in the snow dyeing and ice dyeing technique, the dye is used in powder form and does not need any preparation method.

Everything You Need to Know about Optical Brightening Agents

  What is OBA? Optical brightening agents(OBA) are used to enhance the appearance of fabric and consumer apparel. On exposure to the UV rays, they absorb the colors in the spectrum to reemit in the blue range. They are generally used along with other colorants to get the desired shades. They are widely used with plastics to suppress their inherent yellow color and emit brightness. OBAs have a high melting point allowing them to mix with the molten plastic and give any shade easily. The whitening effect exhibited by the OBAs is the reason behind its wide use across different industries and materials. Global Optical Brighteners Market: Uses of Optical Brightening Agents: Optical Brightener in Textile Industries: Optical brighteners are very commonly used in the textile industry to enhance the brightness of the fabric.

What are Optical Brightening Agents? Bleaching is a popular method to decontaminate a colorized fabric. Although it is quite effective, the method often leaves a yellowish tinge, rather than pristine white. To achieve complete whitening of fabric, other methods must be used. One such method is using Optical Brightening Agents. Also known as fluorescent brighteners, these chemical compounds when exposed to invisible ultraviolet rays, emit visible light of lower energy leading to a brighter and whiter fabric. It is important to note that improper application or inappropriate quantities can lead to unexpected results and even yellowing. The unique property has made Optical Brightening Agents a much sought-after in a variety of industries like Textiles, Plastics, Paper, and Cosmetics. Where are Optical Brightening Agents Used?
