Knitted Fabric Preheating and Setting Tunnel Furnace

The knitted fabric preheating and setting tunnel furnace is a continuous thermal processing equipment specially developed for knitted fabrics.The equipment uses precisely controlled high-temperature airflow to uniformly heat the fabric after width adjustment, eliminating residual stress inside the fibers.It can effectively prevent knitted fabrics from developing edge curling, deformation, and dimensional instability during subsequent processing. It is a key equipment for modern textile dyeing and finishing enterprises to improve product competitiveness.

Product Applications

Stress Elimination:

Smooths and stabilizes the internal fiber structure of knitted fabrics.

Dimensional Stability:

Controls fabric shrinkage rate to prevent deformation.

Edge Curling Prevention:

Solves the problem of edge curling in open-width knitted fabrics.

Baking and Color Fixing:

Used for functional finishing agent baking and fabric setting processes.

Product Parameters

Product Features

Precise Temperature Control:

The equipment adopts a segmented independent circulating air duct design, ensuring extremely small temperature differences inside the chamber.

Stable Operation:

The ultra-wide mesh belt conveyor combined with variable frequency speed regulation enables tension-free heating of fabrics.

Energy Saving and High Efficiency:

The high-density insulation layer reduces heat loss, and the special hot air circulation system saves up to 30% energy.

Intelligent Operation:

The PLC touch screen allows one-button setting of process parameters and supports recipe storage.

FAQ

Q1: What types of knitted fabrics are suitable for this equipment?

A1: It is suitable for various types of knitted fabrics, including cotton, polyester, nylon, spandex blended fabrics, and other lightweight or heavy knitted materials.

Q2: Which heating source provides the best cost performance for the tunnel furnace?

A2: For large-scale continuous production, natural gas or heat transfer oil heating is recommended. For small production volumes or facilities without gas supply conditions, electric heating is recommended.

Q3: How can the equipment ensure that fabrics are not stretched or damaged during the setting process?

A3: The equipment adopts a tension-free ultra-wide conveyor mesh belt system combined with front and rear speed synchronization control, ensuring that fabrics remain naturally relaxed and are heated evenly.

Q4: What is the maintenance interval for daily equipment maintenance?

A4: The transmission chain should be inspected and lubricated weekly. The filter screen should be cleaned every shift. The heating system is recommended to undergo a comprehensive inspection once every quarter.

Q5: Does the equipment support non-standard customization according to the actual factory space?

A5: Yes. The number of drying chamber sections, total equipment length, feeding and discharging heights, and effective working width can all be customized according to the factory layout.
