Choosing the right fabric is a game-changer when it comes to printing custom clothing, especially in Australia, where weather conditions, comfort, sustainability, and wearability all play a role in customer decisions. Whether you’re running a print-on-demand business, managing a custom uniform shop, or sourcing tees for your next event, understanding the core differences between cotton, polyester, and blended fabrics is essential.
This guide breaks down everything you need to know about these three popular fabric types, from their fibre compositions to print compatibility, care needs, and environmental impact. You’ll learn how each fabric performs, what its ideal uses are, and what to consider when choosing between them for your specific needs.
Quick Takeaways
- Fibre Composition Matters: Cotton and polyester are made from different fibre sources. Cotton is natural and breathable, while polyester is synthetic and durable. Blended fabrics combine the two.
- Cotton is soft, breathable, biodegradable, and supports most printing methods. But it takes longer to dry and can wear out faster.
- Polyester dries quickly, resists shrinking, and lasts longer. But it’s not biodegradable, may cling to the body, and doesn’t always suit all print techniques.
- Blends (like 65/35 poly-cotton) aim to offer the best of both worlds, durability with softness, but may cost more and still carry some of polyester’s drawbacks.
- When selecting fabrics for your garments, consider:
- The intended use (e.g. casual wear, sportswear, workwear)
- The fibre type and weave
- The weight and feel of the fabric
- The design and print method compatibility
- The environmental impact and sustainability of the fabric choice
In the sections ahead, we’ll go more into fibres and fabrics, how they’re made, how they behave, and which ones are better suited for custom t-shirts, polos, hoodies, uniforms, or activewear, especially if you’re catering to the Australian market. Let’s break it down.
What Fabric is Really Made Of: Fibres Explained
Before diving into cotton, polyester, and blends, it’s important to understand what fabric actually is and why the fibres behind each material matter so much.
Fabrics are made from fibres, long, thread-like structures that are twisted into yarns, then woven or knitted into cloth. These fibres are what give each fabric its distinct properties: softness, strength, stretch, breathability, and more.
There are two major categories of fibres used in clothing:
Natural Fibres
These come from plants, animals, or minerals and are prized for their breathability and comfort.
Examples include:
- Cotton – the most commonly used plant-based fibre in apparel.
- Flax (linen) and burlap – also plant-based.
- Wool and silk – derived from animals.
- Asbestos – once used in textiles, but is no longer common due to health concerns.
Cotton is the star of the natural fibre category when it comes to everyday wear like t-shirts and casual garments.
Synthetic Fibres
These are man-made fibres, typically derived from petroleum-based chemicals or regenerated cellulose sources (like wood pulp).
Examples include:
- Polyester – the most common synthetic fabric.
- Nylon, acrylic, and olefin – also derived from petrochemicals.
- Rayon, acetate, and triacetate – technically semi-synthetics, often made from wood pulp.
Synthetic fibres are engineered for durability, moisture-wicking, and resistance to wrinkles or shrinkage.
Blended Fabrics: The Middle Ground
Blended fabrics combine natural and synthetic fibres to merge the best qualities of each. The most popular blend in apparel is polyester-cotton (poly-cotton). These are created by combining yarns spun from both fibre types in varying ratios, such as 65/35 or 50/50.
Blends aim to balance comfort with performance, which is why they’re so widely used in everyday and active clothing.
Fabric Construction Methods
Understanding the fibre base and how it’s constructed helps you choose the right fabric for comfort, durability, and decoration, especially when printing or embroidering garments for your customers. Once fibres are spun into yarn, they’re turned into fabric using two main methods:
- Weaving: Weaving is interlacing two sets of yarn at right angles (warp and weft). Woven fabrics tend to be structured, strong, and slightly less stretchy.
- Knitting: Knitting is looping a single yarn to create interlocking rows. Knitted fabrics are generally softer, more elastic, and less prone to wrinkling, making them ideal for t-shirts, hoodies, and activewear.
Here is a detailed comparison of cotton, polyester, and blended fabrics in terms of softness, breathability, moisture wicking, print compatibility, shrink resistance, drying time, sustainability, durability, and cost:
| Feature | Cotton | Polyester | Blended Fabrics |
| Softness | Very soft | Less soft | Balanced (depends on blend ratio) |
| Breathability | Excellent | Lower | Moderate |
| Moisture-wicking | Absorbs moisture | Wicks sweat | Some blends wick better than cotton |
| Print compatibility | Screen, DTG | Sublimation or DTG only | Varies – test before printing |
| Shrink resistance | Shrinks unless pre-shrunk | Resists shrinkage | Shrinks less than cotton |
| Drying time | Slow | Fast | Faster than cotton |
| Sustainability | Biodegradable | Not biodegradable | Mostly non-biodegradable |
| Durability | Moderate | Excellent | Stronger than cotton alone |
| Cost | Affordable | Varies (may cost more) | Mid-range to premium |
All About Cotton: The Go-To Fabric for Breathability and Printability
Cotton is one of the most widely used natural fibres in the world and for good reason. It’s soft, breathable, easy to print on, and generally affordable. For many Australian businesses in the garment printing space, 100% cotton t-shirts and polos remain a popular choice for both retail and promotional apparel.
But not all cotton is the same. The quality, feel, print results, and longevity can vary depending on the type of cotton fibre and how it’s processed.
Popular Types of Cotton Used in Apparel
Here’s a breakdown of the most common cotton types used for garments like t-shirts, hoodies, and polos:
- Ringspun Cotton
A finer, smoother, and more durable version of regular cotton. It’s spun to straighten and thin each fibre, resulting in a softer finish, perfect for retail quality printed t-shirts. - Combed and Ringspun Cotton
Combines ringspun softness with a combing process that removes impurities. It offers a smooth surface for printing, reduced fraying, and an overall premium feel. - Slub Cotton
This cotton has a unique textured finish due to uneven yarns. It feels airy and lightweight, ideal for relaxed, casual wear, but may not suit detailed prints. - Pima Cotton
Known for its long fibres, this is one of the softest and most durable cotton types. It’s also more resistant to pilling and fading, but comes at a higher cost. Great for luxury merch or high-end retail lines. - Piqué Cotton
Recognisable by its raised weave or waffle like texture. It’s breathable and holds shape well, commonly used in polo shirts. Often blended with other cotton types like Pima. - Organic Cotton
Grown without synthetic fertilisers or pesticides, organic cotton is eco conscious and often feels softer. In Australia, demand for sustainable apparel has made this a growing choice for ethical brands.
Cotton’s Strengths
- Soft, breathable, and gentle on skin
- Naturally biodegradable, better for the environment
- Easy to print on with screen printing and DTG
- Absorbs moisture (feels cool in hot weather)
- Widely available and affordable in many forms
Where Cotton Falls Short
- Absorbs moisture, so it dries slowly
- Can shrink or wrinkle if not pre-shrunk
- Printed designs may fade faster than on polyester
- Slightly less durable under heavy wear or repeated washing
When to Choose Cotton
Cotton is ideal for:
- Every day tees for events, streetwear, or brands focused on comfort
- Merch where screen printing and DTG results matter
- Hot Australian climates, where breathability is a must
- Eco-conscious consumers, especially when using organic cotton
Polyester: The High-Performance Fabric Built to Last
Polyester is a synthetic fibre made from petroleum-based sources, and it’s known for being durable, fast-drying, and resistant to shrinking or wrinkling. While it doesn’t have the natural softness of cotton, it shines in areas where longevity, moisture resistance, and ease of care are critical.
In Australia, polyester is often the fabric of choice for sportswear, workwear, and outdoor uniforms, where heat, sweat, and heavy use are common.
Why Polyester Stands Out
- Moisture wicking performance: It pulls sweat away from the body to evaporate quickly, keeping wearers dry.
- Fast drying: Especially useful in humid or coastal climates.
- Fade and shrink resistant: Designs stay sharper longer, and garments retain shape after multiple washes.
- Stain and odour resistance: Useful for athletic and work settings.
- Lightweight and durable: Holds up under frequent use and outdoor conditions.
Limitations of Polyester
- Not biodegradable, Synthetic origin makes it less eco friendly than natural fibres.
- Less breathable, can trap heat, making it less comfortable in very hot conditions.
- Can feel clingy, especially with static buildup.
- Irritates sensitive skin; Some people may find it itchy or harsh.
- Limited print compatibility, Standard screen printing doesn’t always bond well with polyester. DTG and sublimation are better suited.
Ideal Use Cases for Polyester
Thanks to its technical performance, polyester has become a go to fabric for function first garments, and when blended well, it can enhance both style and wearability.
Polyester is well-suited for:
- Athletic wear, team uniforms, gym gear
- Workwear that needs to endure sweat, dirt, and repeated washing
- Outdoor clothing, especially in cooler or variable weather
- Sublimated garments, where full-colour prints are heat-pressed into the fabric
Blended Fabrics – Creating a Balance Between Comfiness and Reliability
Blended fabrics, especially poly-cotton blends, are designed to merge the strengths of both cotton and polyester, softness with resilience, printability with moisture wicking, affordability with durability. They’re a favourite in the Australian custom apparel market thanks to their versatility.
Whether you’re printing t-shirts, uniforms, or retail ready merch, blended fabrics offer a dependable middle ground when neither cotton nor polyester alone quite fits the bill.
Common Blend Ratios and What They Mean
Different blend ratios result in different fabric performances. Here are some of the most common combinations:
-
- 90% Cotton / 10% Polyester: Super soft and breathable, but retains more of cotton’s shrinkage and drying limitations. Often used in fashion forward or premium tees.
-
- 65% Polyester / 35% Cotton: One of the most popular blends. Durable, low shrink, fast drying, and cost effective. Common in sportswear, uniforms, and promotional tees.
-
- 60% Polyester / 40% Cotton: Slightly softer than 65/35 with slightly higher cotton content. Good for comfort focused performance apparel.
-
- 50% Cotton / 50% Polyester: Balanced feel and performance. Offers decent breathability with good durability. Popular for activewear and casual workwear.
-
- 52% Cotton / 48% Polyester: A near even blend that leans just enough towards softness while keeping polyester’s benefits intact. Ideal for retail style tees and lifestyle brands.
-
- Tri-Blends (e.g. 25% Cotton / 50% Polyester / 25% Rayon): These add rayon for a softer, silkier feel with a relaxed drape. Great for fashion tees, but more delicate and may not suit all printing styles.
Benefits of Blended Fabrics
-
- Combine cotton’s comfort with polyester’s strength
-
- Fast drying and more resistant to shrinking than pure cotton
-
- More durable than standard cotton shirts
-
- Maintain shape well through washes
-
- Available in various weights and finishes (heathered, smooth, textured)
Drawbacks to Consider
-
- Still not biodegradable, especially blends with higher polyester content
-
- May cling or cause irritation for sensitive skin
-
- It can be trickier to screen print, depending on the blend ratio
-
- Higher cotton content blends may still shrink slightly
-
- Cost may be higher than standard cotton, depending on the blend
Best Use Cases for Blends
Blends are particularly helpful for high-turnover environments, like gyms, events, hospitality uniforms, and schools, where you want gear that looks good but lasts even longer. Blended fabrics are ideal when:
-
- You want a balance between softness and performance
-
- You’re producing sportswear, trade uniforms, or event tees
-
- You need apparel that’s easy to wear, maintain, and print on (with the right method)
-
- You’re after a modern, retail style feel with subtle textures (e.g. heathered tri-blends)
How to Choose the Right Fabric for Custom Apparel
Selecting the ideal fabric isn’t just about price or printability; it’s about understanding your customer’s needs, how the garment will be used, and the long term performance of the fabric. Whether you’re printing t-shirts, polos, or uniforms, these five key factors will help you make the right fabric choice every time.
1. Purpose: What’s the Garment For?
Think about where and when the item will be worn; hot Aussie summers call for breathability, while cooler climates may require thicker, more insulating fabrics. Start by considering the end use:
-
- Everyday casual wear: Cotton or cotton rich blends offer comfort and breathability.
-
- Activewear or team gear: Polyester or poly heavy blends dry fast and hold up well under pressure.
-
- Uniforms or workwear: Blends are more durable and easier to maintain.
-
- Eco-conscious collections: Organic cotton or recycled polyester options are better aligned with sustainability goals.
2. Fibre Composition: Natural vs Synthetic vs Blend
For printing businesses, fibre composition also affects how ink behaves. For example, screen printing tends to look sharper on cotton, while sublimation works best on polyester. Each fibre type brings something different to the table:
-
- Cotton: Best for softness, breathability, and ease of printing.
-
- Polyester: Offers strength, quick drying, and better shape retention.
-
- Blends: Strike a balance between comfort and performance.
3. Fabric Weight: Light, Medium, or Heavy?
Choose the weight based on climate, usage, and garment type. Fabric weight affects how the garment feels, wears, and drapes:
-
- Lightweight fabrics (120–150 GSM): Ideal for summer tees, sportswear, or layering.
-
- Midweight fabrics (150–180 GSM): Good for general use t-shirts and casual wear.
-
- Heavyweight fabrics (200+ GSM): Best for premium shirts, winter wear, or durability-focused apparel.
4. Design and Print Compatibility
Always test or sample first if you’re unsure how a design will behave on a new fabric. Your chosen printing method will influence fabric selection:
-
- Screen printing: Performs best on cotton and some blends.
-
- DTG (Direct to Garment): Works on high cotton content and pre treated polyester blends.
-
- Sublimation: Requires 100% polyester or poly heavy blends for vibrant, long lasting results.
-
- Embroidery: Performs well on most fabrics, but textured weaves (like pique) or thick materials hold stitching better.
5. Environmental Sustainability
Choose sustainable options where possible and highlight these benefits in your marketing to attract eco aware buyers. With growing demand for eco friendly products in Australia, sustainability is more than a trend; it’s a competitive edge.
-
- Cotton is biodegradable, especially organic varieties.
-
- Polyester is not biodegradable, but recycled polyester options (rPET) offer a lower impact alternative.
-
- Blends can be harder to recycle, but they offer longer garment life, which reduces turnover and waste.
