Digital Printing Thickener Wet Process Manual

Product Overview:

Digital printing thickener LN-09 is a high-molecular-weight modified plant gum-based paste, suitable for high-speed digital printing machines. It offers stable sizing, high color yield, sharp pattern outlines, and excellent brightness. This product provides superior color and hand feeling compared to sodium alginate.

Technical Specifications:

Recommended Application Method:

Formula (by weight):

• LN-09 thickener: 3.5–5%

• ZH-08H: 4%

• Urea: 10–13%

• Synthetic thickener: 1%

• Baking soda: 3%

• Anti-staining salt: 0–1%

• Water: X% (to make 100%)

Procedure:

1. Add the required amount of water into the mixing tank and start stirring.

2. Add anti-staining salt, then slowly add the corresponding amount of digital printing thickener ZH-08H.

3. Stir for 40 minutes.

4. Add baking soda and urea, then continue stirring for another 10–20 minutes until fully dissolved.

5. Let the mixture sit for 2–4 hours to allow complete swelling before use.

Recommended Sizing Process:

• Sizing method: Rotary screen or other methods suitable for high-speed machines.

• Fixation temperature: 110–120°C.
  Note: Do not exceed the recommended temperature, as overheating may cause yellowing of the fabric.

Precautions:

• Clean the sizing equipment thoroughly before use to ensure no residual finishing chemicals remain.

• After drying, seal the fabric immediately with plastic film to prevent uneven moisture absorption, which may affect printing quality.

Storage Conditions:

Store the product in a clean, dry, and well-ventilated environment. Keep sealed to avoid exposure to moisture.
