Materials science: Patches & appliques

A patch usually consists of three main components:

1. Backing material (base fabric)

The backing material forms the base of the patch. Commonly used materials include:

• Cotton – robust, easy to sew

• Polyester – dimensionally stable, durable

• Canvas / Twill – particularly hard-wearing

This material ensures that the patch remains stable and can be easily sewn or ironed on.

2. Motif material (embroidery, print, or weave)

The motif varies depending on the type of patch:

Embroidered Patches

• Motif made from embroidery thread (polyester or cotton)

• Raised, textured surface

• Very durable & high quality

Woven Patches

• Motif directly woven into the fabric

• Fine details possible

• Flat, clean look

Printed Patches

• Motif via textile printing

• Ideal for complex graphics

• Smooth surface

3. Backing (attachment)

The backing determines how the patch is attached:

• Sew-on patches – no coating, traditionally sewn on

• Iron-on patches – with adhesive coating (usually thermoplastic)

• Velcro patches – with Velcro system (hook & loop)

Many patches can also be sewn on, even if they are iron-on – for extra hold.

Characteristics & Advantages of Patches

• Very durable

• Individual & interchangeable

• Resistant to wear and tear

• Ideal for clothing, bags & vests

• Classic scene accessory

Patches are a sustainable way to upgrade or repair clothing.

Areas of Application for Patches

• Jackets & Vests (e.g., Battle Jackets)

• Hoodies & Shirts

• Bags & Backpacks

• Caps & Accessories

Especially in the Gothic, Metal, and Punk scenes, patches are a personal statement.

Care & Durability

• Do not iron directly over them if possible

• Gentle wash recommended

• Sewn-on patches last longer than just ironed-on ones

• For heavy use: sew on additionally
