Textile dyeing is one of the most vital and complicated parts of the textile industry. Behind every color of clothing, there is a well-thought-out dyeing and scientific formulation used. A dyeing recipe is a well-thought-out recipe. It's not only dye and water; it is a balanced combination of multiple dyes, chemicals, and adjuncts so that it meets the target. And this is done multiple times if the color is to be consistent every time it is made.

In the past, the dye formulation process involved a lot of manual work, but now it is done digitally.  The dyeing formulation process is dominated now by the use of spectrophotometers and AI software like PeColor form 3nh.

What is textile dyeing?

Textile dyeing is the process of putting color on textile material like fibers, yarns, or fabrics. The aim is to get uniform and lasting color that withstands washing, rubbing, and light. Ordinarily, each type of fabric used varies and thus requires a specific dye. For instance, cotton fabric uses reactive or direct dyes, and polyester fabric uses disperse dyes. The dye used is dependent on the chemical properties of the fibers used in the fabric.

The Importance of Dyeing in the Textile Industry

The first thing a customer sees is the color of the item. It can be a textile garment or a beauty product. It is essential in the forming and shaping of a product and very important in the textile industry marketing. With accurate dyeing, the quality of a product and the speed in which the product is made can be improved without increasing the cost. With the current dyeing techniques, the cost of dyeing is reduced, which minimizes wastage and the need for re-dyeing. Dyeing is also becoming more environmentally friendly with advancements in technology and the use of digital recipes for dyeing. 

Different Methods of Textile Dyeing 

The method chosen for dyeing the fabric can be done in different stages of fabric production. Lastly, it is done in the finished product. Each stage in the production of fabric has an impact on color intensity, fabric structure, and cost of production. The main dyeing techniques are:

Piece Dyeing 

Finished and woven or knitted fabrics are dyed using this method. It is great for solid color fabrics and flexibility in production. The fabric is placed in a dye bath, and the dye is evenly circulated around the fabric. 

Yarn Dyeing 

As the name suggests, the fabric has not yet been woven, which means the fabric is not created yet. This is the best method for multicolored checkered or striped patterns. 

Fiber Dyeing 

This is when the processing of dyeing is done to the individual strands before the fabric is created. This is mostly done with wool or synthetic materials and is one of the best methods for colorfastness and uniformity.

Garment Dyeing

Is it the dyeing of fully stitched clothing? It’s done in the fashion industry for color variations and small batch productions.

Each system has different optimal results due to different concentrations and types of dyes and auxiliaries, which requires different recipes.

Understanding Dye Classes and Their Applications.

Different dyes can be sorted into separate categories based on the dyes' method of application, solubility, and the chemical bond the dyes have with the fibers. In order to create and develop recipes, an understanding of the different classes of dyes and their application is necessary.  

• Direct Dyes: Mainly used for cotton. Direct dyes are easy to use and are water-soluble but have moderate wash fastness.  

• Reactive Dyes: They are used mostly for cotton and viscose and form covalent bonds to the fibers, which also ensure exceptional colorfastness.  

• Disperse Dyes: Used for polyester. These dyes are non-water-soluble and are dispersed in water using a dispersing agent.  

• Vat Dyes: These are known for their excellent fastness and are applied using a reduction-oxidation process. Indigo used in denim is a classic example.  

• Acid Dyes: Best suited for protein fibers such as wool and silk.  

Every dye class is designed specifically with a unique recipe template comprising different auxiliaries such as leveling agents, wetting agents, and pH controllers.

Common Dye Solution Formulas in Textile Dyeing

Dyeing a fabric requires a concentration of dye solution for a given time. It also requires attention to the fabric weight, desired depths of shade, and type of dye to determine the dye percentage. Firstly, let's start with a basic formula for a reactive dye bath.

These parameters change with the type of fiber, dye, and the results you want. However, advanced systems, such as PeColor, can use the input data to derive these values removing the possibility of human error. In other words, it helps to achieve perfect color matches.

Calculating Dyeing Recipes

Dyeing fabric requires attention to detail. The OWF (on weight of fabric) principle is one way to calculate dyeing recipes:

Dye Amount (g) = (Fabric Weight × Shade Percentage) / 100

For example, to dye 10 kg of cotton fabric to a 2% shade:

Dye = (10 × 2) / 100 = 0.2 kg or 200 g.

The calculation of other chemicals such as salt, alkali, and dispersing agents is determined by concentration per liter of dye bath. Other factors like temperature, time, and liquor ratio (L:R) of the dye bath will determine the final effect of dyeing.

This is the basic calculation used in digital dyeing systems to automate the calculations using a database and predictive colors based on algorithms to determine dyeing values.

Textile Dyeing Recipe Measurement

Dyeing recipes are some of the final steps to take before a design is put into production. Each dye and auxiliary must be measured and mixed with precise values.

Here’s how we go about dyeing fabric:

Step 1. Determine fabric weight: 

The very first thing needed is to figure out the weight of the fabric to be dyed. The weight is needed to create a recipe using “on weight of fabric (OWF)” calculations.

Step 2. Shade Percentage: 

The shade percentage indicates the depth of the color. For example, a percentage of 0.5% will produce a pastel shade, while 4% will produce a deeper tone.

Step 3. Measuring dye and chemicals

The pre-calculated dye amount is weighed with precision, very often using an analytical balance. Likewise, the salts, alkali, and dispersant auxiliaries are added based on standard solution concentrations.

Step 4. Prepare dye solution and Color Measurement: 

The dye is dissolved in water at the appropriate temperature, where sufficient stirring is done to ensure all the dye is dissolved. Extract the solution and place it in the colorimetric dish of the spectrophotometer for color measurement.

The 3nh TS4020 Liquid Spectrophotometer is designed specifically for measuring the color of liquid samples, including dyes, inks, and pigments. Equipped with advanced optical sensors and a high-resolution spectrophotometric system, the instrument captures detailed spectral data across the visible light range (400–700 nm). This allows for precise quantification of color attributes such as hue, saturation, and lightness, which are critical for evaluating dye quality and consistency.  The ts4020 instrument can be used to verify that the dye solution matches the desired color before it is applied to fabric, reducing the risk of rework and material waste.

Step 5. Mixing & Application. 

The solution is added to the dyeing machine or beaker where dyeing will occur. The material is constantly moved to guarantee even distribution of dye into the fabric.

Step 6. Fixation and Washing. 

After dyeing, the fabric goes through fixation (thermal or chemical), which is followed by washing and soaping to remove unfixed dye.

Every step of the process is accurately measured to avoid any color difference, which leads to the dreaded re-dyeing. Color is uploaded into the machine, which will systematically go through the steps in software, reducing human error.

Textile Colour Matching with a Spectrophotometer 

 In managing the colors in a textile, a spectrophotometer measures the dye's color against a color standard (lab dip or customer sample), generates a correction recipe, and compares the sample with the previously mentioned standards. The human eye is subjective while a spectrophotometer produces objective and consistent measures of reflected, absorbed, or transmitted light.

In dyeing textiles, the spectrophotometer measures a dyed fabric's specific color. For spectrophotometers, precision is virtually no limit. Instruments from 3nh or Konica Minolta identify the differences in hue, brightness, or chroma. With spectrophotometers integrated with dyeing textiles with color formulation software like PeColor, recipe predictions are possible.

hese predictions minimize the need for dyeing recipes that depend on trial and error. These spectrophotometer predictions save time, energy, and dyeing fabric resources. In contemporary textile dyeing and color management software, the spectrophotometer and color formulation program are the main attractions.

Challenges in Dyeing Recipe Management

Though technology increase has made dyeing recipe management a lot easier, it still has a few challenges.

1.  Same Recipe, Different Batches: Every now and then, using the same recipe for dyeing will cause variations. This is the case when there is a differing temperature, preparation of the fabric, or even the hardness of the water used. Different colors may result.

2.  Manual Errors: Although most dyehouses have recipe automation, there are still a lot of recorded recipes. The colors will vary for a given recipe if there is a mistake in reading or weighing, or if information is not written and/or recorded correctly.

3.       Not Fully Integrated Systems: Without a centralized database to utilize, recipe information ends up stored within different locations like spreadsheets or even handwritten notes. This makes replicating your successful batches a tedious task.

4.       Insufficient Documentation:  In the case of a color problem, the cause is uncovered, but it can be a challenge to retrieve systematic problem data if working on a report that has never been created.

 5.       Problems with Growing: In the case of a lab recipe, smaller-sized samples are manageable; however, it is unlikely that the recipe will be successful once it has been scaled up for bulk production.

Most of the above problems are resolved by the use of PeColor. This digital dyeing recipe software systematizes your processes, organizes your recipe database for easy access, and adjusts scales to ensure color consistency from lab to production.
