Breaking Through the Barriers in Deep Dyeing: Strategies and Solutions

 

In textile dyeing industry, dyeing effect of dark fabric directly impacts product value and market competitiveness. However, production often faces challenges:  

Customers demand for deep colors (e.g., jet black, navy) often fall short.  

Repeated dye additions spike costs and environmental pressure.  

High-temperature, high-pressure dyeing keeps energy consumption high.  

Aging equipment struggles with modern deep-dyeing technology requirements.  

 

Let's understand some theories and principles of the basic dark effect firstly:

1. Chromophores 

The core of dark color effect is regulation of absorption wavelength of the light wave by molecular structure of dye. Dark effect can be achieved by group substitution of absorption wavelength redshift (such as thiomethyl substitution of hydrogen atoms), because the dye molecular structure has both chromophores (wavelength range 380-780mm) and chromophores.

Example: Modifying triazole disperse dyes by replacing hydrogen with "thiomethyl (CH3S-)" group.  

Applicable fibers: Nylon/acetate.  

Results: 30%+ deeper shade, wash fastness 4–5, light fastness 6.  

 

2. Surface Optics

In K/S value evaluation system, adjusting fabric microstructure (e.g., diffuse reflection) enhances visual depth.  

 

3. Dyeing Kinetics 

Traditional methods focus on dye uptake rate, this method is very clear for dark-colored effect and reaction effect is obvious, so it is one of the primary considerations for dyeing work. The dyeing rate is directly related to adsorption/diffusion rate of dyes, swelling degree of fibers and the molecular structure of dyes affect the penetration depth.

• Higher temperatures (≤130°C for polyester) improve penetration but risk fiber damage.  
• Electrolytes boost dyeing but must be added gradually to prevent aggregation.  
• Low-temperature auxiliaries reduce energy use and protect heat-sensitive dyes.  

 

 

Speaking of this, choice of suitable dyeing machine model is also the hardware basis of dark dyeing. Choosing the right dyeing machine is one of the steps to enhance dark color effect. Different fiber and dye series need to be matched with specific equipment: 

1) High-Temperature Overflow Dyeing Machine  

TY-JL636 HTHP Overflow Dyeing Machine is suitable for dyeing synthetic fibers such as polyester and nylon with disperse dyes. The design working maximum temperature is 140°C, facilitating fiber swelling and dye penetration. Equipped with precise temperature control system, reduce hydrolysis rate of dyes (temperature deviation controlled within ±0.5–1°C). Combined with its newly designed structure, this model dyeing equipment achieves ultra-low bath ratio 1:6, reducing dye consumption by 30%.

 

2) Airflow Dyeing Machine 

The airflow dyeing machine is ideal for dark dyeing processes of sensitive fibers (such as microfiber polyester). Driven by high-speed airflow to circulate fabric, it effectively minimizes color variation caused by mechanical friction. Compared to traditional overflow dyeing machines, this technology significantly reduces energy consumption of water and steam.

 

3) Jet Dyeing Machine

Jet dyeing machine is equipped with high-pressure jet system, which enhances penetration ability of dye liquor. This makes it particularly suitable for achieving uniform dyeing on high-density fabric (such as curtain fabric) while  improving the K/S value significantly.

 

 

In addition to understanding principles and how to select suitable dyeing machines for achieving excellent deep color effect, there are other key approaches.

A. Enhanced pre-treatment measures 

Alkali Deweighting:

The alkali deweighting rate of polyester fabrics should be precisely controlled within 10%-20%. This process significantly reduces fiber surface roughness (Ra value decreases by 30-50%). Key parameters requiring strict control include:

• Alkali concentration gradient (recommended: 5-8% NaOH solution)
• Temperature uniformity (maintained at 98±1°C)
• Reaction time (adjusted to 30-60 min based on fabric weight)

Two industrial process routes currently exist: batch-type dyeing machines and continuous alkali deweighting equipment. Laboratory comparative tests demonstrate that continuous equipment reduces the deweighting CV value from 12.3% to 5.8%. Prioritizing continuous systems is advised to ensure uniformity and avoid localized over-hydrolysis-induced strength loss (warp breaking strength reduction should be controlled below 15%).

 

Plasma Treatment:

A plasma treatment system is recommended for functional high-end fabrics (atmospheric pressure plasma equipment is advised). This technology proves particularly effective for pre-treating cellulose-blended fabrics like linen and ramie. After 300-500W radio frequency power treatment:

• Fiber contact angle decreases from 120° to below 30°
• Dye uptake rate increases by 18-25% (K/S value improves by 0.5-1.2)
• Color fastness enhances by 0.5-1 grade

Equipment selection must balance processing efficiency (recommended line speed ≥20m/min) with ROI period (CAPEX payback should be ≤36 months). Modular designs are recommended to accommodate diverse production requirements.

 

B. Chemical Modification of Fibers

Cationic Modification: Applicable to cellulose fibers (regenerated textile materials made from natural plant cellulose). By directly adding quaternary ammonium reagent (e.g., CHPTAC) into fabric dyeing machine, positive charge groups are introduced to enhance binding with cationic dyes (This method enables simultaneous cellulose modification and dyeing in a one-bath process, effectively shortening production steps and reducing energy consumption). K/S value can increase by 100%-200% after modification. However, attention should be paid to the uniformity of modification and its impact on fiber strength.

 

Bioenzyme Treatment: Cellulase treatment is applied to natural fibers like cotton/linen. The enzyme decomposes amorphous regions of cellulose fibers, disrupting the crystalline structure on the fiber surface to create micro-pores and cracks. This process:

1. Increases effective contact surface area, enhances dye adsorption sites
2. Removes partial impurities from natural fiber surfaces, reduces dye penetration resistance
3. Improves fiber hydrophilicity, accelerates dye solution penetration

This modification mechanism optimizes both the physical structure and chemical properties of fibers for enhanced dyeability.

 

C. Rare Earth and Deepening Agents

Rare Earth Application: Dyeing machine with automatic dosing system to precisely control addition of rare earth chloride (LaCl₃), improving dye uptake rate by 1.52 grade. However, wastewater treatment requires use closed-loop recycling dyeing system.

 

Selection of Deepening Agents: Resins with good compatibility with dyes (e.g., modified silicones) can be prioritized to avoid color shifts caused by post-finishing. For example, deepening agent containing nanoparticles can be used for polyester deep black dyeing to enhance blackness through diffuse reflection.

 

 

The achievement of dark dyeing effects constitutes a systematic engineering endeavor that requires synergistic coordination among dyeing & finishing equipment, dyeing technology parameters and dye chemical systems. During process design phase, manufacturing enterprises must scientifically select compatible dyeing machine models and auxiliary systems based on the differential characteristics of textile fibers. Notably, with iterative upgrades in intelligent dyeing control technology, dyeing processes are progressively realizing technological breakthrough toward high-precision controllable process and low-energy consumption production mode. This evolution signifies that dyeing-finishing industry is poised to usher in new era of intelligent process innovation.

The processes of cotton knitting fabric(scouring, bleaching , dyeing and etc.) is generally carried out in the overflow machine. During the entire processing, the fabric remains in a rope-like state. The fibers constantly bend and deform in the dyeing machine, the original hydrogen bonds are constantly broken while new hydrogen bonds are constantly formed. Sometimes the newly formed hydrogen bonds cannot be fully restored, thus forming chicken claw marks and dead creases on the fabric surface.

In the single-sided fabric structure, tension of the two sides of yarn is asymmetric. After fabric is folded in one direction for a long time, it is difficult to recover. Therefore, among various structures,  especially on fabrics with less or larger weight (eg. plain weave and sweatshirt fabrics) are more prone to crease problems. The generation of creases is also closely related to yarn count and twist. The finer the yarn count and the higher the twist, the greater the possible reversal and untying of the yarn, and the more likely it is to cause crease problems.

 

 

The main process steps leading to creases: scouring and bleaching

1. The general dyeing and finishing process typically involves: fabric preparation → seam sealing → boiling and bleaching in the fabric dyeing machine → dyeing → soaping → color fixing → softening → fabric out from dyeing machine → dehydration → drying. It is commonly believed that creases mainly form in the dyeing machine. However, after rigorous experimental verification by our engineers, it has been found that most cotton knits actually develop creases during the boiling and bleaching stage, which are just not easily observable before dyeing.

 

2. Based on the years of experience of our engineers, the following types of fabric and equipments are prone to developing creases during the boiling and bleaching stage:

Fabric factors: Single-sided cotton fabrics with lighter or heavier weights (e.g., weights <150g or >300g), especially cotton spandex (with elastane) fabrics.

 

Machine factors: Compared to L-shaped overflow fabric dyeing machine, J-shaped overflow fabric dyeing machine are more prone to creating creases due to their stronger stretching force. Air-jet fabric dyeing machine, on the other hand, are less likely to cause creases because the fabric is fully blown open by high-pressure air at the nozzles, allowing the fibers to "rest" from tension, which aids in eliminating internal stress and reducing creasing issues.

 

Process factors: Fabrics that have not undergone prestretching are more prone to creasing. Fixing the fabric under high temperatures can improve fiber proximity and orientation, stabilize fiber morphology and reduce likelihood of changes occurring in dyeing machine, which is beneficial for reducing creases.

Solutions of scouring and belaching creases 

1. General Method: During boiling and bleaching, as well as dyeing, polyacrylamide-based lubricants are added. The primary role of this type of lubricating agent is to "reduce friction between fabrics and between fabrics and machinery," but it is difficult to resolve creases formed during boiling and bleaching.

 

2. Solution Proposed in This Article: To improve creases during boiling and bleaching, the following auxiliaries, processes, and operations are employed. Satisfactory results have been confirmed through applications by multiple clients.

 

Auxiliaries:

A. Preferentially select a high-concentration and highly soluble polyacrylamide-based anti-crease agent JET (non-ionic) for use in the bath. Its role is to reduce friction between fabrics and between fabrics and machinery.

B. Select new type of anti-crease softener RCE (non-ionic). Its role is to impart good softness and smoothness to the fabric itself, as well as to provide level dyeing properties. 

The combined use of these two auxiliaries is the core of this method.

 

Process:

Reduce the heating rate; the focus is on reducing the cooling rate, with an optimal range of 1.0 to 1.5°C/min.

 

Operations:

Before entering the dyeing machine, the gray fabric should be placed in an area with high humidity in workshop to allow for sufficient moisture regain. During moisture regain, the fibers undergo some swelling, and internal stresses are partially eliminated, which is conducive to reducing creases. After the gray fabric is loosened, it should be allowed to freely pass through a J-shaped trough, while simultaneously being pressed by a press roll or stretched by rollers, which is conducive to eliminating internal stresses and reducing creases.

 

3.Process example

Before boiling and bleaching, add refining permeant, etc., anti-wrinkle agent JET and anti-wrinkle softening agent RCE in the bath, do not heating firstly, cycle for 20 minutes after entering the cloth, so that the grey cloth is fully moistened and the auxiliary agent fully reacts with the fabric fiber. If bleaching is required, caustic soda and hydrogen peroxide can be added before heating. Reduce the rate of heating; Especially to reduce the cooling rate, generally 1.0 ~ 1.5℃/min is better; And it must be completely cooled to 50 ° C to discharge the liquid for dyeing.

 

Other items to prevent creases

1. In order to prevent the generation of creases, it is recommended to add polyacrylamide type lubricant - JET in the bath during dyeing, and reduce the cooling rate.

2. When dehydrating and dry cloth, open width rolling water dry cloth can be used, which not only improves the efficiency of dry cloth, but also helps to solve the problem of creasing. 

3. When stacking cloth, it is recommended that the weight should not be too large and the time should not be too long, especially when the wet cloth is stored.
