Embroidery thread materials – polyester, viscose and other fibres

The choice of embroidery thread material influences not only the appearance of a design but also how reliably the thread can be processed and how the finished embroidery performs during use.

Polyester and viscose (rayon) are widely used in machine embroidery, but their properties make them suitable for different requirements. Other materials, such as cotton, polyamide and specialised fibres, offer additional possibilities for decorative and functional embroidery.

Embroidery thread materials are the fibre materials used to manufacture machine embroidery threads. Their characteristics influence stitch appearance, processing reliability, abrasion resistance and care properties. The appropriate material depends on the embroidery design, the textile being embroidered and the intended end use.

During machine embroidery, the thread repeatedly passes through the needle eye and the material before becoming part of the finished stitch. This creates mechanical stress that different fibre materials withstand differently.

For embroidery applications, the following characteristics are particularly relevant:

• Lustre and appearance: The fibre material and filament structure influence how light is reflected by the embroidered surface.
• Processing reliability: Tensile strength, elongation and abrasion resistance affect how the thread behaves during embroidery.
• Stitch formation: Thread flexibility and surface characteristics influence the formation of consistent stitches.
• Durability: The finished embroidery must withstand the expected mechanical stress, washing and environmental conditions.

These properties help determine which material is best suited to a specific embroidery application.

Polyester and viscose are both established materials for conventional machine embroidery. However, they offer different advantages.

Polyester embroidery threads combine good strength and abrasion resistance with reliable processing characteristics.

Their mechanical properties make them particularly suitable for industrial embroidery applications involving high processing demands or frequent washing.

Polyester is often preferred for:

• Workwear and frequently washed garments
• Sportswear and everyday clothing
• Embroidery exposed to mechanical abrasion
• Industrial embroidery requiring consistent processing reliability

For example, when embroidering leather, the increased friction within the needle penetration can place considerable stress on the thread. Polyester is generally less susceptible to this mechanical stress than viscose.

Viscose embroidery threads are particularly valued for their characteristic lustre and soft, flexible structure.

They are frequently selected for decorative embroidery where the visual appearance of the thread is a primary consideration.

Typical applications include:

• Haute-couture embroidery
• Decorative logos and motifs
• Embroidery requiring a particularly lustrous appearance
• Applications where softness and flexibility are important

However, viscose has lower tensile strength and abrasion resistance than polyester. Depending on the embroidery design and machine settings, this may increase the risk of thread breakage or require adjustments to the processing speed.

Viscose is also generally less suitable for demanding washing and bleaching conditions.

The material should not be selected based on appearance alone. Processing requirements and the expected conditions of use must also be considered.

Besides polyester and viscose, other fibre materials are used when particular visual or functional characteristics are required.

Cotton creates a natural textile appearance and can be suitable for decorative embroidery where the characteristic surface of a staple-fibre thread is desired. Its processing behaviour differs from that of conventional continuous-filament embroidery threads.

Polyamide offers high tensile strength and abrasion resistance. However, its comparatively high elasticity can make stitch formation more demanding and increase the risk of unwanted loops.

Silk and wool are used for specialised decorative applications. Silk provides a characteristic lustre, while wool can create a fuller, more textured appearance. Mostly used for hand embroidery.

Regenerated cellulose fibres such as lyocell and modal can provide alternatives to conventional viscose. Their suitability depends on the actual yarn construction and the requirements of the embroidery application.

For technical applications, meta-aramid and other specialised fibres can provide additional properties such as flame resistance. These requirements are covered in more detail in the chapter on technical and functional embroidery threads.

The same embroidery design can produce different results depending on the selected thread material.

When evaluating an embroidery thread, the following questions should be considered:

• What appearance and surface effect should the embroidery achieve?
• How much mechanical stress will the thread experience during processing?
• Does the embroidery need to withstand frequent washing or abrasion?
• Is the material being embroidered particularly demanding, such as leather?
• Are specific technical properties required?

Changing the thread material may also require adjustments to needle selection, thread tension, machine speed or embroidery design parameters.

For demanding applications, sample embroidery should be carried out using the intended material, thread and machine settings before series production.
