Cotton vs Polyester: The Short Answer
Cotton is the better choice when softness, breathability and a natural handfeel matter most, which is why it dominates t-shirts, hoodies, denim and everyday casualwear. Polyester is the better choice when strength, quick drying, colour retention and low shrinkage matter most, which is why it dominates sportswear, outerwear linings and hard-wearing uniforms. Most real garments sit somewhere between the two, using a blend that borrows the strengths of each.
The rest of this guide explains why those differences exist, how they show up in a finished garment, and how to choose a composition for a specific product. If you are earlier in the process, our overview of types of fabric for clothing places both fibres in the wider picture.
How Cotton and Polyester Are Made
Cotton is a natural cellulose fibre that grows in the boll of the cotton plant. After picking and ginning, the short fibres are cleaned, combed or carded, and spun into yarn. The way the yarn is spun changes the finished feel considerably, which is why ring-spun and combed cotton feel softer than open-end yarn. We cover that difference in our guide to ring-spun vs combed cotton.
Polyester is a synthetic fibre made from polyethylene terephthalate (PET), a polymer produced from petrochemicals. The polymer is melted and extruded through fine nozzles to form continuous filaments. Those filaments can be used as they are, textured to add bulk and stretch, or cut into short lengths called staple fibre and spun like cotton. Staple polyester is what makes a poly-cotton blend possible, because it can be spun together with cotton in one yarn.
Because polyester is engineered, its properties can be adjusted at the extrusion stage. Filament thickness, cross-section and finishing treatments determine whether a polyester fabric feels slick and technical or soft and almost cotton-like. Cotton, by contrast, is shaped mainly by the growing conditions and the spinning process.
Cotton vs Polyester: Head-to-Head Comparison
The table below summarises how the two fibres typically behave in knitted and woven garments. Individual results vary with yarn quality, fabric construction and finishing, so treat it as a starting point for conversations with your factory rather than a specification.
Cotton vs polyester at a glance
| Factor | Cotton | Polyester |
|---|---|---|
| Handfeel | Soft, natural, slightly dry; softens with washing | Ranges from slick and technical to soft and brushed, depending on finishing |
| Breathability | High; fibres absorb moisture and let air through | Lower in most constructions; can feel warm unless the fabric is engineered for airflow |
| Moisture handling | Absorbs a lot of moisture and dries slowly | Absorbs very little; moves moisture along the surface and dries quickly |
| Strength and abrasion | Good, but weaker when wet and with age | Very high; resists abrasion, stretching and tearing |
| Shrinkage | Can shrink noticeably unless pre-shrunk and tested | Very low shrinkage under normal washing |
| Wrinkling | Wrinkles easily | Resists wrinkles and recovers shape well |
| Pilling | Low in good combed yarn, higher in cheap short-staple yarn | Prone to pilling in staple fabrics, because strong fibres hold the pills on the surface |
| Colour and dyeing | Takes many dye types well; colours can fade with washing | Needs disperse dyes at high temperature; colours are usually very durable |
| Static and odour | Low static; holds less odour | Can build static and hold odour unless treated |
| Care | Tolerates higher wash temperatures; may need tumble-dry care | Easy care; dislikes high ironing heat |
General characteristics of the two fibres. Fabric construction, yarn quality and finishing can shift any single row.
Moisture: The Difference That Explains Most of the Others
Moisture behaviour is the single most useful way to understand why cotton and polyester feel and perform differently. Textile scientists describe it using moisture regain, the amount of water a fibre holds at standard temperature and humidity, expressed as a percentage of its dry weight. Cotton holds roughly 8.5 per cent. Polyester holds roughly 0.4 per cent, so it barely absorbs water at all.

In practice this means cotton feels comfortable against the skin because it absorbs sweat and spreads it through the fabric, but it takes a long time to dry and feels heavy and cold when soaked. Polyester does not absorb sweat into the fibre, so moisture-wicking fabrics pull it along the surface and let it evaporate. That is why sportswear leans on polyester, and why a cotton running top feels clammy by the end of a session. For performance categories see our sportswear manufacturer guide.
Indicative Performance Ratings
The matrix below converts the same characteristics into a simple five-point scale across the properties buyers ask about most. A third column shows a typical poly-cotton blend, because blends rarely sit at either extreme.

Blends: Getting the Best of Both
Blending is how most commercial fabrics resolve the cotton vs polyester trade-off. Adding polyester to cotton improves strength, reduces shrinkage and wrinkling, and speeds up drying. Adding cotton to polyester improves softness, breathability and the way the fabric feels on skin. The ratio decides which character dominates.

Common blend ratios and where they are used
| Blend | Character | Typical use |
|---|---|---|
| 100% cotton | Softest and most breathable; shrinks and creases the most | Premium t-shirts, heavyweight tees, denim, summer casualwear |
| 80/20 cotton-polyester | Soft with better shape retention and less shrinkage | Fleece hoodies, sweatshirts, joggers |
| 60/40 cotton-polyester (CVC) | Cotton still leads; stronger and more stable | Tees, polos, mid-price basics |
| 50/50 poly-cotton | Balanced; easy care and lower cost | Promotional tees, workwear, uniforms |
| 65/35 polyester-cotton (TC) | Polyester leads; very durable and quick drying | Workwear, shirts, school and corporate uniforms |
CVC stands for chief value cotton, meaning cotton is the majority fibre. TC denotes a polyester-majority blend.
Blends do come with trade-offs. A blended garment is harder to recycle than a single-fibre one, and in screen printing the polyester content can bleed dye into the ink, a problem called dye migration that your printer needs to know about in advance. If you are deciding between decoration methods, screen printing, embroidery and DTG each handle blends differently.
Which Fibre Suits Which Garment
Choosing a composition is easier when you start from the garment and the way it will be worn rather than from the fibre. The table below shows the usual starting point for the main categories.
Typical fabric choices by garment
| Garment | Common choice | Why it works |
|---|---|---|
| T-shirts | 100% cotton, or cotton-rich blend | Softness and breathability; blends add shape retention |
| Hoodies and sweatshirts | 80/20 cotton-polyester fleece or French terry | Warmth and softness with less shrinkage; see our hoodie fabric guide |
| Sportswear and activewear | Polyester with elastane | Moisture wicking, fast drying, strength and stretch |
| Workwear and uniforms | 65/35 polyester-cotton | Durability, easy care and colour retention through repeated washing |
| Jeans and denim | Cotton, often with a little elastane | Traditional look, comfort and fading character |
| Shirts | Cotton or poly-cotton | Breathable cotton for comfort; blends for easy care and fewer creases |
| Outerwear and linings | Polyester or nylon | Strength, water resistance when coated, and low weight |
Printing, Dyeing and Decoration
The fibre in your fabric decides which decoration methods will work. Cotton accepts water-based and pigment inks and is the natural partner for direct-to-garment printing, which we explain in our DTG printing guide. Polyester does not absorb ink well, so full-colour designs on white polyester are usually produced by dye sublimation, where the dye turns into a gas and bonds with the fibre. The limits of that method, including its need for white or light fabric, are covered in our sublimation printing guide.
Dyeing follows the same logic. Cotton is dyed with reactive or direct dyes at moderate temperatures, while polyester needs disperse dyes at high temperature. In a blend, the two fibres take different dyes, which is why heathered and melange effects are possible but exact colour matching between batches requires care. Ask your factory how it controls shade between lots, especially for matching sets.
Sustainability: A Fair Comparison
A fair look at cotton vs polyester on sustainability starts with a simple point: neither fibre is simply good or bad. Conventional cotton is a thirsty crop that can involve heavy pesticide use, but it is renewable and biodegradable at end of life. Polyester is derived from fossil carbon and sheds microplastic fibres in washing, but it is durable, light to ship, and can be made from recycled bottles or textile waste. A long-lasting garment that is worn many times usually has a lower impact per wear than a cheap one that is discarded, regardless of fibre.
For brands that want to improve their footprint, the practical options are cotton from certified or lower-impact sources, recycled polyester with traceable documentation, and blends designed with end-of-life in mind. Our guides to sustainable fabrics and organic cotton t-shirt manufacturing go further into certification and claims, and why you should be cautious with broad environmental language.
Cost and Sourcing Considerations
On price, cotton vs polyester is not a simple ranking. Cotton is an agricultural commodity, so its price can move with harvests, weather and demand, and that volatility reaches fabric quotes. Polyester prices follow petrochemical markets and are generally steadier, which is one reason poly-cotton blends are common in budget lines and uniform programmes. Fabric weight, yarn quality and finishing usually influence price more than the fibre label alone, so compare like for like and specify weight in GSM. Our fabric GSM guide explains how to do that.
Before committing to bulk, test the fabric you intend to use. Shrinkage, colour fastness and pilling are the three issues that most often separate a good sample from a bad delivery, and they behave differently in cotton, polyester and blends. Our garment testing guide lists what to request.
How to Choose Between Cotton and Polyester
The cotton vs polyester decision becomes much easier when you work through it in a fixed order, starting from the product rather than the fibre.
A five-step decision path
- 1Define the useEveryday wear, sport, work or occasion wear? The use case narrows the options quickly.
- 2Rank your prioritiesDecide whether softness, durability, drying speed or price matters most.
- 3Pick a compositionChoose 100% cotton, a cotton-rich blend, a balanced blend or polyester based on the ranking.
- 4Set the weightSpecify GSM and construction so quotes can be compared fairly.
- 5Test before bulkSample the exact fabric and check shrinkage, colour fastness and pilling.
When two options look similar on paper, make both as samples and compare them side by side after a few wash cycles. A fabric that feels best on day one is not always the one that looks best after ten washes.
How Ruhrose Approaches Fabric Selection
Ruhrose develops hoodies, jersey, denim and woven casualwear for UK buyers, with production in Bangladesh. Fabric choice is part of the sampling conversation: we discuss composition, weight and finish against your target price and the way the garment will be worn, then sample before bulk. If your product falls outside our core categories we will say so early. What jersey buyers should check before bulk orders is a good companion read.
