• Achieves a more refined and polished finish.
• Enhances garment durability by setting seams and shapes more effectively.

Precautions:

• Avoid over-steaming, which can shrink or distort some fabrics.
• Test on a small, hidden area first, especially for delicate or synthetic fabrics.
• Use caution with dark colors to prevent water stains or shine marks.

Dolly pressing / Steam air finish

In the garment industry, dolly pressing, also known as a steam air finisher or form press, is a technique used to remove wrinkles and refresh garments without applying direct pressure. This method is particularly beneficial for delicate fabrics or complex garment structures where traditional pressing might cause damage or alter the intended shape.

How It Works:

1. Garment Placement: The garment is placed onto a form or mannequin that matches its size and shape.
2. Steam Application: Steam is released through the form, permeating the garment to relax fibers and eliminate wrinkles.
3. Air Circulation: After steaming, hot air circulates to dry the garment, setting its shape and ensuring a crisp finish.

Applications of Dolly Pressing:

Dolly pressing is commonly used for:

• T-shirts and Blouses: To remove wrinkles without flattening decorative elements.
• Sportswear: To refresh garments without compromising fabric elasticity.
• Delicate Fabrics: Such as silk or lace, where traditional pressing could cause damage.

This method is advantageous in high-volume settings like garment manufacturing and laundry services, as it efficiently processes garments while maintaining their quality and appearance.

Steam Tunnel Pressing in Garments Industry

Steam tunnel pressing is an industrial finishing process used to remove wrinkles and improve the appearance of garments at a large scale. It is commonly used in garment manufacturing, distribution centers, and laundries for mass production.

How It Works:

1. Garment Loading: Garments are hung on hangers and placed on a conveyor system.
2. Steam Application: The conveyor moves the garments through a tunnel where high-pressure steam is released. This steam penetrates the fabric, relaxing the fibers and removing wrinkles.
3. Hot Air Drying: After steaming, hot air is blown to dry the garments and set their shape.
4. Cooling Section: Some tunnels have a cooling zone to stabilize the garment before packing.

Applications:

• T-shirts and Polos: To remove fold marks and improve appearance.
• Pants and Trousers: For wrinkle removal without pressing sharp creases.
• Jackets and Outerwear: To relax fabric and enhance drape without direct contact.

Advantages:
