Study Notes
Press Finish Garment
- Pressing is the application of heat, moisture, and pressure to fabrics, garments, or parts to give shape, mold, or creases into geometric forms.
- It creates smooth surfaces and perfect forms.
- Pressing is a critical finishing process in the apparel industry, often used during assembly or as a final step.
Categories/Types of Garment Pressing
- No pressing: Some garments, like underwear, briefs, and swimwear made of knitted fabric, don't require pressing.
- Minimum pressing: Some garments, such as night gowns, knitted T-shirts, and leisurewear, need minimal pressing using steaming or dry air.
- Under pressing: Minimum pressing is often done to specific garment parts before sewing to aid in the sewing process (e.g., jackets, trousers).
- Final pressing: Pressing garments after assembly using heat to finish shape and appearance (e.g., jackets, trousers, and skirts). Special machines are used for this final stage.
- Permanent pressing: A specialized pressing method used to maintain a garment's shape after washing (e.g., to retain darts and pleats). High temperatures and steam are used.
Purposes of Garment Pressing
- Removal of wrinkles and creases: Pressing removes unwanted wrinkles and creases formed through washing or production.
- Applying creases: Creasing can enhance a garment's aesthetic appeal.
- Shaping: Pressing helps in shaping garments using darts or seams to set the garment shape and fit before the final assembly (important on specific garments).
Methods and Equipment of Garment Pressing
- Pressing is essential in the garment industry to remove unwanted creases, wrinkles, improving appearance and creating desired shapes.
- Different garment types may use different pressing methods and equipment because of varied design and material.
- Different types of pressing equipment are used based on the type of garment (e.g., buck presses, iron pressing, block/die presses, form presses, steamers, steam tunnels).
Iron
- Ancient irons used heated coal/wood.
- Modern irons use electricity, with a regulator to control temperature.
- Steam irons use steam to aid in ironing.
- Specialized air suction beds in modern irons control excess crinkling.
- Iron weights range from 1-15kg.
Steam Press
- A static buck and head shape is used in steam presses.
- Fabric is placed on the buck while the head is positioned above, applying heat and pressure.
- An ironing bed spreads fabric layers.
- Air suction and steam flow systems are incorporated for controlled movement and shape.
- Table supports the fabric during pressing.
Steam Air Finisher
- Also called "puffer" or "dolly press," this type of machine utilizes a frame with a steam-and-compressed-air system.
- The form size varies according to garments shape.
- This pressing method is used for garments like T-shirts, jeans, and sportswear.
Steam Tunnel
- Garments hang on hangers, and are pressed in chambers through a running rain of steam to remove wrinkles.
- The steam relaxes the fabric and removes wrinkles.
- This pressing is used for T-shirts and knitted garments.
Flat Bed Pneumatic
- The head is suspended on rocker arms for alignment with the bed.
- Push buttons control raising and lowering.
- Specialized pads and centrifugal suction control moisture.
- Setting a preset time releases the head.
- The head's temperature is controlled digitally.
Vacuum
- Vacuum systems remove excess steam produced in pressing, cutting, and sewing processes.
- Potential causes of high utilization include improper resource allocation, inefficient use, and lack of maintenance.
Types of Pressing Equipment
- Buck Press
- Iron Pressing
- Block/Die Pressing
- Form Pressing
- Steamers
- Steam Tunnels
- Flat Bed Pneumatic
Buck Pressing
- Commonly used in manufacturing slacks, skirts, and jackets.
- Components include lower buck, a movable head with a linkage system, buck padding system, vacuum frame, manual/automatic control for steaming, vacuum, heat, and pressure, and silicon-covered foams.
- Used for in-process and finish pressing.
Iron Pressing
- Point presser: for collars, cuffs, curved seams, darts.
- Tailors ham: For darts and curved seams.
- Sleeve board: Small ironing boards for narrow garments elements like sleeves and trouser legs.
- MITT: for sleeve caps and ruffles.
Block Pressing
- A molding process to establish product conformance to a shape.
- Changes the surface characteristics and dimensions of a product.
- Fabric is placed on a form and then pressure, heat, and steam are applied.
- Useful for creasing patch pockets and other details.
Form Pressing
- Forms mimic the shape of finished garments.
- Steam is forced through the garment.
- Reduces positioning and repositioning time.
Steamers
- Use steam only to mold and smooth garments.
- Types of steam equipment include jets, guns, puffs, and tunnels.
- Used to form and stabilize garment shapes.
Steam Tunnels
- Primarily for final pressing.
- Wrinkles are removed in a chamber by average pressure of steam.
- Garments move through a steam jet nozzle.
- Reduces labor costs and speeds up the pressing process.
Iron
- Utilized to remove fabric wrinkles using a heated iron.
- Smooths fabric and removes wrinkles.
- The temperature controls are commonly around 180-220 degrees Celsius, though this could vary depending on type of fabric.
- The iron causes the fibers to straighten, causing the material to hold the new shape.
Types of Iron
- Dry iron: Light-weight, approximately 1.4 kg with a heat range between 70 °C and 240 °C. Control is commonly +/- 3 degrees Celsius.
- Electric steam iron: Commonly used for a wide variety of tasks, especially under-pressing. Uses a central/independent boiler to provide steam to the iron. Heat generated is controlled by a thermostat, and steam source can be a main supply or a small adjacent boiler. Steam function is activated by a button.
Types of Iron Tables
- Vacuum table: Vacuum is sucked through the table surface to lay the garment flat, while moisture and heat are drawn out.
- 'Up-steam' table: Steam rises to the top surface of the table to moisten the garments; good for use on garments such as knitted fabrics. Using stainless steel prevents corrosion and ensures long and trouble-free use.
- Blow-up table: A table that uses air pressure on the garment to eliminate ironing marks; The cushions of air assist in finishing garment without leaving marks. Introduced by VEIT in 1969.
