Easy Dyeing Recipe Calculation Formula with Proper Example

Introduction:

A dyeing master must need to know dyeing recipe calculation to measure accurate dyestuff and chemical. The entire process occurs in lap dip. Lab dip is a process in which the buyer’s swatches are matched with the percentage of dyes in the laboratory. In the large scale production, lab dips are important for shade matching, as well as detaching the characteristics of dyes and chemicals that will be used in the large scale production. This is an important task before bulk production. The purpose of this article is to help beginners who are starting out in dyeing production by giving them a formula to calculate the dyeing recipe. Before going to recipe calculation you have to know about stock solution.

What is Stock Solution?

Stock solutions are concentrations of known, accurate concentrations that will be diluted for use in laboratories in the future. Example: 1% stock solution means, 1 gm dyestuff or solid chemical diluted in 100 ml water. If the chemical is liquid form than 1 ml chemical is dissolve in 99 ml water, then this liquor is called 1% stock solution.

Why Need Stock Solution?

Usually, in a laboratory, we use a small amount of dye stuff that is difficult to measure in balance, that is why we make stock solution in a laboratory. However, in bulk production, it is not needed to make stock solution. Because, in bulk production, need high amounts of dyestuff and chemical. So don’t need to prepare stock solution in case of bulk production.

Dyeing Recipe Calculation Formula:

Only two formula require for dyeing recipe calculation. One is for auxiliaries and other for dye stuff.

Exercise:

Now, we will do a total dyeing recipe calculation by using above mentioned dyeing recipe calculation formula. We will using following recipe:

Chemical	Amount(gm/l)
Wetting agent	1.0-2.0 gm/l
Sequestering agent	1.0-2.0 gm/l
Leveling agent	0.5-1.0 gm/l
Soda ash	1.0-5.0 gm/l
Salt	20-30 gm/l
Direct dye	2%
Sample weight	5 gm
M:L	1:20

At first we do calculation for auxiliaries (chemical):

Calculation for Dyestuff:

Why Need to Know Dyeing Recipe Calculation for a Textile Engineer?

Dyeing Recipe calculation is most important for a textile engineering, especially for work in dyeing and finishing sector. Here I described some reasons why this calculation is important for a textile engineer.

Color Matching: Textile engineers need to color matching for various textile products. To achieve the desired color and shade, he must to know right way calculation of dyes and chemicals.
cost control: Calculation help to prepare costing, minimizing waste and reducing production costs.
Environmental Impact: Efficient calculations contribute to environmentally friendly practices by minimizing the use of water and chemicals.
Quality Assurance: Recipe calculations play a vital role in quality assurance. By accurate calculations, final product meets quality standard.
Color Fastness and Stability: Recipe calculations help in determining the supper combinations between dyes and chemical. As a result, it is possible to achieve good color fastness properties of textile materials.

so, this easy way of dyeing recipe calculation. I tried my best to present simply as possible. If you have any question about this calculation, please let me know below comment box. All information is collected for authentic source and books. Don’t forget to share my post and help me to reach more Textile lover people and Students.
