1. What are seamless, glued-together t-shirts from local brands?

Seamless (or bonded garment) T-shirts are made using heat bonding or welding technology instead of traditional sewing .

In this process, the fabric layers are bonded together using TPU heat-activated adhesive, seam tape, or specialized adhesive film , under the influence of precise temperature, pressure, and pressing time.

Features of seamless adhesive t-shirts

There are no raised seams on the surface.
The edges of the shirt are thin, flat, and aesthetically pleasing.
It’s stretchy and doesn’t feel tight when worn.
Suitable for local fashion brands, sportswear, underwear, and activewear.

3. Production process of seamless glued t-shirts for local brands.

A seamless t-shirt production line typically includes the following main steps:

1. Prepare the ingredients.

Commonly used ingredients:

Cotton jersey fabric
Polyester / Spandex
Nylon / Poly blend
TPU film adhesive or seam tape

The following types of fabrics need to be ensured:

Heat resistance
Good elasticity
Suitable surface for bonding.

2. Pattern design and sample development

The designers will:

Creating a T-shirt pattern
Determine the adhesive application location.
Design the collar, placket, shoulders, and hem.

This process optimizes the adhesive application to ensure the durability and aesthetics of the product.

3. Cutting fabric with a laser cutting machine.

In seamless manufacturing, laser cutting machines are commonly used for:

Precise fabric cutting
Neat fabric edges
Minimize unraveling.

Laser cutting technology ensures high precision in fabric details before gluing.

4. Apply adhesive and heat press.

This is the most important step in the production of seamless shirts.

This process includes:

Apply TPU film adhesive to the desired bonding location.
Insert the fabric pieces into the heat press.
Set temperature – pressure – time
Heat press to melt the glue and bond the fabric.

Once the glue cools, the two layers of fabric will be firmly bonded together.

5. Seam pressing and finishing the fabric edges.

After applying the adhesive, areas such as:

hem
collar
sleeve
garment placket

The seams will be pressed together to create a smooth and beautiful surface.

6. Print logo and finalize the product.

Local brands often use:

heat transfer printing
silk printing
decal printing

The shirt was then:

quality control
pack
Distribute to the market.

4. Equipment needed in the production of adhesive-backed T-shirts

A seamless t-shirt production line typically includes:

1. Fabric laser cutting machine

Precise fabric cutting
Clean cut edges
Increase production speed.

2. Heat press machine for gluing

Press TPU adhesive onto the fabric.
Create a strong connection.

3. Seam sealing machine
