Jacquard Bleach Thickener for Creating Thickened Bleach Paste on Fabric

🧴 How to Use – Jacquard Bleach Thickener

Jacquard Bleach Thickener is a synthetic thickener designed to be mixed with bleach to create a thick, stable bleach paste.
It does not work on its own.

🧪 Preparing the Bleach Paste

Mix Bleach Thickener with bleach until a smooth, thick paste is formed.

🎨 Application on Fabric

Apply the thickened bleach using:

• brush
• stencil
• screen printing tools

Allow the bleach to react until the desired discharge effect is achieved.

⚖️ General Mixing Ratios

• For painting:
  1 tablespoon (15 ml) Bleach Thickener per 1–2 tablespoons (15–30 ml) bleach
• For printing:
  1.5 tablespoons (22 ml) Bleach Thickener per 1–2 tablespoons (15–30 ml) bleach

Adjust the amount of thickener to achieve the desired consistency.

⏱️ Important Usage Notes

• Dilute with water for lower viscosity or slower reaction
• Do not leave bleach mixture on fabric longer than 3 hours
• Thickened bleach remains stable for 24–36 hours
• Suitable for cellulosic and synthetic fibers
• Do not use on silk or wool — use Jacquard deColourant instead

🥇 How to Choose: Jacquard deColourant or Bleach Thickener

Both products are used for fabric discharge, but they work in very different ways and are suited to different working styles and materials. Choosing the right one depends on the level of control you want, the fiber you are working on, and how comfortable you are with the process.

Jacquard deColourant removes dye through heat activation. Until heat is applied, nothing happens, which means the process is fully controllable and reversible. You can rinse it out, adjust your design or start over before committing. Color removal begins only when heat is applied with an iron, steam or a heat gun. This makes deColourant ideal for precision work, layered designs and sensitive fibers, especially protein fibers such as silk and wool, where bleach cannot be used. The resulting color is not always white and depends on the original dye.

Jacquard Bleach Thickener, on the other hand, relies on the chemical action of bleach. The thickener turns liquid bleach into a stable paste so it can be painted, stenciled or printed without spreading. Once applied, the reaction starts immediately and cannot be reversed. The results are often stronger, more organic and high-contrast, making it well suited for cotton, linen and denim, but unsuitable for silk or wool.

🧠 Core Difference

Jacquard deColourant
→ Removes dye through heat activation
→ Chlorine-free
→ Nothing happens until heat is applied
→ Maximum control and reversibility before activation

Jacquard Bleach Thickener
→ Removes color through bleach chemistry
→ Acts immediately
→ Cannot be reversed once active
→ Requires experience and timing

🎯 Control & Visual Results

deColourant

• Clean negative effects
• Precise, design-oriented results
• Ideal for layered work and re-coloring
• Final color depends on the original dye (not always white)

Bleach Thickener

• Strong, organic, high-contrast effects
• Bold visual impact
• Ideal for stencil work and large areas

🛠️ Activation Method

deColourant
🔥 Heat (iron, steam or heat gun)
→ Can be washed out before activation

Bleach Thickener
🧪 Chemical reaction with bleach
→ Action begins immediately upon application

🧩 When to Choose Each

Choose deColourant if:

• you work on silk or wool
• you want control and safety
• you need the option to correct before activation
• you want negative and layered effects

Choose Bleach Thickener if:

• you work on cotton or denim
• you want strong color removal
• you use stencil or screen printing
• you are comfortable working with bleach
