Important applications of textile dyeing chemicals

Chemicals in the textile dyeing industry not only help create beautiful colors but also directly affect fabric durability, product safety and production efficiency. Below are the main chemical groups and their applications:

Bleaching and fiber cleaning chemicals

The bleaching process removes impurities and natural oils from the fabric fibers, creating a clean surface for better dye absorption. Some common chemicals:

• Phosphoric Acid (H₃PO₄): Removes metal compounds in water, helping to clean fabric fibers.
• Acetic Acid (CH₃COOH 99.85%): Adjust pH and clean fiber surface before dyeing.
• Javen (Sodium Hypochlorite – NaClO): Whitens fabric fibers, sterilizes and removes residual organic matter.

Coloring and color fixing chemicals

To ensure the dye color is even, not patchy and durable, it is necessary to use suitable dyeing chemicals:

• Sodium Chloride (NaCl 99% – Industrial salt): Increases the dye's ability to adhere to fabric fibers.
• Sodium Tripolyphosphate (STPP 94%): Improves the solubility of dyes, allowing the color to penetrate more deeply and evenly.

Finishing and post-dyeing chemicals

After dyeing, the fabric needs to be finished to ensure color fastness, wrinkle resistance, stain resistance and improve product quality.

• Sodium Hydrosulfite (Na₂S₂O₄): Removes excess color, helping to stabilize fabric color.
• Caustic Soda (Sodium Hydroxide – NaOH 32% & 45%): Soften fabric fibers, increase mechanical strength.

Chemicals for treating textile wastewater

Textile wastewater contains many organic substances, heavy metals and colorants, which need to be treated before being discharged into the environment.

• Iron II Chloride (FeCl₂ 15 – 30%): Coagulation of pollutants in wastewater.
• Acetic Acid (CH₃COOH): Neutralizes alkalinity in wastewater, making treatment more effective.

📌 EXPANDED FAQ – DEEP ANSWERS ABOUT TEXTILE DYEING CHEMICALS

• How do textile chemicals affect health and the environment?
  • Textile chemicals can affect health if not used and handled properly. Some chemicals such as Sodium Hydroxide (NaOH) May cause irritation to skin, eyes and respiratory tract. In addition, azo dyes can decompose into aromatic amines – a group of substances that are potentially carcinogenic.
  • Environmentally, wastewater from the textile dyeing industry may contain heavy metals, persistent dyes and dyeing auxiliaries change the pH of water, affecting the ecosystem. Therefore, the use of modern wastewater treatment system as flocculation Iron II Chloride (FeCl₂) and neutralize the pH with Acetic Acid (CH₃COOH) is extremely important.
• Is there any way to reduce the amount of chemicals consumed in the fabric dyeing process?
  • To reduce the amount of chemicals used while still ensuring dyeing efficiency, businesses can apply the following measures:
    • ✅ Water-saving dyeing technology (Low Liquor Ratio – LLR): Reducing water usage means reducing the need for neutralizing, alkalizing and cleaning chemicals.
    • ✅ Use of high efficiency dyeing auxiliaries: Sodium Tripolyphosphate (STPP) Helps reduce the need for other inorganic salts, optimizing color absorption.
    • ✅ Applying waterless dyeing technology (Supercritical CO₂ dyeing): Some fibers can be dyed using this technology without the use of water or traditional detergents.
    • ✅ Reuse of treated wastewater: Wastewater treatment system by RO membrane or coagulation with FeCl₂ can help reuse 60-80% of water in the dyeing process.
• Why dyed fabrics can fade and how to fix it?
  • Hair color can fade for many reasons, including:
    • 🔹 Wrong choice of color fixing chemicals: If the correct ratio is not used Sodium Chloride (NaCl) or Sodium Tripolyphosphate (STPP) During the color fixing process, the dye may not adhere firmly to the fabric fibers.
    • 🔹 Improper heat treatment: If the temperature during the dyeing process is not at the optimum level (usually from 80-120°C depending on fiber type), the dye cannot bond firmly to the fabric structure.
    • 🔹 The pH of the detergent is unstable: After dyeing, if not Neutralize with Acetic Acid (CH₃COOH), the fabric fibers may continue to react with the remaining alkaline chemicals, causing fading when washed.
  • ✅ How to fix:
    • Check the color fixative formula again.
    • Adjust the temperature and steaming time according to each type of fabric.
    • Ensure proper pH neutralization before fabric leaves the production line.
• What standards must textile dyeing chemicals meet to ensure safety?
  • Textile chemicals must comply with many international safety standards to ensure that they are not harmful to humans and the environment. Some important standards include:
    • 📌 OEKO-TEX Standard 100: Ensure chemicals do not contain toxic substances exceeding the permitted level and are safe for skin contact.
    • 📌 REACH (EU Regulation No 1907/2006): Regulations on chemical control in the textile industry in Europe, limiting harmful substances such as heavy metals, aromatic amines from azo dyes.
    • 📌 ZDHC (Zero Discharge of Hazardous Chemicals): Committed to completely eliminating toxic chemicals in the production process.
    • 📌 GOTS (Global Organic Textile Standard): Strict requirements for the safe use of chemicals in organic textile production.
  • ✅ Businesses should choose suppliers with full certification to ensure products meet international safety standards..
• How to store textile chemicals to ensure optimal performance?
  • Textile dyeing chemicals need to be stored properly to avoid deterioration or loss of performance. Some important storage principles:
    • 📌 For liquid chemicals (NaOH, CH₃COOH, FeCl₂):
      • Store in closed box corrosion resistant
      • To place cool, avoid direct sunlight to change the chemical concentration.
    • 📌 For powder chemicals (NaCl, STPP, Na₂S₂O₄):
      • Store in a sealed bag/container to avoid absorbing moisture from the air.
      • Avoid contact with water or humid environment to avoid losing the effect of chemicals.
    • 📌 Chemical storage:
      • Must have good ventilation system, avoid dangerous accumulation of chemical vapors.
      • Arrange chemicals by safety group: Do not mix alkaline chemicals (NaOH) with acids (CH₃COOH) to avoid unwanted reactions.
  • Note: Periodically check the expiry date of chemicals to ensure stable quality before putting them into production.
