Large-Format Xuan Paper Dyeing System

For controlled-temperature dyeing and draw-dyeing of large-format Xuan paper and related paper materials.

The system uses a controlled motion mechanism to move paper through a dye bath. Dye-bath temperature control, dyeing-bar lifting and speed adjustment provide more stable and repeatable dyeing conditions for large-format Xuan paper.

Situation: Conservation, mounting or related paper-treatment work requires large-format Xuan paper to be dyed, but the material size makes it difficult to control speed, temperature and paper orientation during manual movement and immersion.

Problem: Large-format Xuan paper dyeing requires simultaneous management of paper movement, dye-bath temperature, dyeing-bar lifting travel and operating speed.

Job: Pass large-format Xuan paper through a temperature-adjustable dye bath and complete draw-dyeing through mechanical motion, dyeing-bar lifting and speed adjustment.

Desired Outcome: Establish a temperature-controlled, speed-adjustable draw-dyeing workflow for large-format Xuan paper.

Suitable when:

• The principal materials are large-format Xuan paper and related paper materials;
• Continuous draw-dyeing or dyeing of paper is required;
• Dye-bath temperature must be controlled;
• Paper travel or draw-dyeing speed must be adjustable;
• A large paper-processing width and dyeing-bar lifting travel are required;
• The project requires customization according to paper width, dye-bath temperature, lifting travel and laboratory conditions.

If the main task is immersion, dyeing and post-treatment drying of smaller sheets during rare-book conservation, select the Book Conservation Paper Immersion & Dyeing System.

The machine is mainly used to dye large-format Xuan paper. During movement, the paper passes through a tank containing dye solution, whose temperature is controllable.

1. Motion mechanism: A DC motor provides power; a synchronous belt and linear guide serve as the linear-motion elements.
2. Temperature control: A silicone heating belt and temperature-detection sensor are used.

1. The hood base is integrally fabricated from high-quality 304 stainless-steel sheet for high strength and corrosion resistance.
2. The machine body is formed from Q235-A cold-rolled steel sheet.
3. The latest temperature-control technology is used for more stable and accurate temperature control.
4. A 24 V DC variable-speed motor is used. PWM speed-control technology provides precise stepless speed adjustment.
5. A retractable aluminium-alloy paper-drying rack is provided.

Suitable for:

• Dyeing large-format Xuan paper;
• Draw-dyeing large-format paper;
• Paper-treatment workflows requiring temperature-controlled dye solution;
• Dyeing large-format Xuan paper and related paper materials;
• Large-format paper-treatment projects in conservation laboratories and paper-conservation studios.

Project-specific configuration is available according to:

• Paper width;
• Dye-bath dimensions;
• Dye-bath temperature-control requirements;
• Dyeing-bar lifting travel;
• Draw-dyeing speed;
• Laboratory space conditions;
• Paper-drying rack configuration.
