Cotton or polyester. It sounds like a simple question. In practice, it's a decision that affects comfort, durability, decoration quality, care requirements, and how the uniform performs across a range of conditions. Here's how to think through it.

Cotton: the natural choice and its trade-offs

Cotton is the default fabric for most people's experience of comfortable clothing — and for good reason. It's soft, breathable, absorbs moisture, and feels natural against skin. In conditions where physical comfort matters most — long shifts, warm environments, extended wear — cotton is difficult to beat on feel alone.

For uniforms, 100% cotton or high-cotton-content blends (80/20 cotton/polyester) are appropriate for:

• Office and low-physical-activity environments where comfort and appearance are the primary requirements
• Customer-facing hospitality roles where the fabric feel contributes to perceived quality
• Environments where synthetic fabric feel would be uncomfortable over extended wear
• Any application where DTG printing is the specified decoration method (cotton is significantly better for DTG than polyester)

The trade-offs with cotton: it shrinks more than polyester (typically 3–5% on first wash if not pre-shrunk), wrinkles more easily, takes longer to dry, and in high-heat or high-activity environments, absorbs sweat and stays wet longer than performance alternatives. For ironing-required uniforms, cotton requires more garment maintenance from staff.

Polyester: the performance argument

Polyester is a synthetic fibre that outperforms cotton on several specific attributes relevant to workwear. It's dimensionally stable (minimal shrinkage), quick-drying, wrinkle-resistant, and — when treated with moisture-wicking technology — actively moves moisture away from the skin rather than absorbing it.

For uniforms, polyester or high-polyester-content blends are appropriate for:

• Physical roles — tradies, delivery drivers, active service staff, maintenance teams
• Outdoor workers in hot Australian conditions where moisture management is a practical need
• Sports and fitness environments where performance fabric is expected
• Roles requiring hi-vis compliance (most hi-vis fabric is polyester)
• Any application where sublimation printing is the decoration method of choice

The trade-offs with polyester: it can feel less comfortable against skin than cotton in some people's experience, it holds body odour more than cotton without proper antimicrobial treatment, and for some decoration methods (particularly DTG) it produces inferior results. On natural appearance, it often reads as slightly more synthetic than cotton to an attentive observer.

Cotton/polyester blends: the practical middle ground

For most uniform programmes, a cotton/polyester blend — typically 60/40 or 65/35 in favour of cotton — offers the best practical compromise. The cotton content provides comfort and natural feel. The polyester content reduces shrinkage, adds dimensional stability, and improves durability and wash performance.

Blends are the most widely used fabric type in quality workwear and corporate uniform products for this reason. AS Colour's core uniform products, Biz Collection's corporate range, and most mainstream quality uniform brands use blended fabrics as their standard.

Laundering and care implications

Cotton: wash cold or warm (max 40°C for most programmes), line dry or tumble dry low, iron if required. High-temperature washing degrades cotton faster and may cause more shrinkage.

Polyester and blends: machine wash warm (40°C), tumble dry low, minimal ironing required due to wrinkle resistance. Avoid high-temperature washing and drying — it can damage polyester fibres and affect moisture-wicking treatments.

For commercial laundering programmes (hospitals, large hospitality operations), confirm the fabric specification is compatible with your laundering process before ordering in volume. High-temperature commercial laundering requires specific fabric specifications that not all uniform garments meet.

The decoration compatibility summary

• Embroidery: Works on both cotton and polyester, with appropriate digitising and stabilisation for performance fabrics
• Screen printing: Works on both; water-based and discharge inks perform best on cotton
• DTG: Cotton and high-cotton blends only; performs poorly on high-polyester fabrics
• DTF: Works on both cotton and polyester
• Sublimation: Polyester only (90%+ polyester); does not work on cotton
