What is polyester?
Polyester is a synthetic material made from polyethylene terephthalate (PET) fibers, the same plastic found in water bottles.
Known for its cost-effectiveness, durability, and versatility, polyester is prevalent in the fashion industry, from outerwear to activewear.
Its durability also makes it ideal for household and industrial products like ropes and air filters.
The pros and cons of polyester
Pros
Durability – Polyester is known for its long-lasting strength, making it ideal for clothing, home goods, and industrial products.
Wrinkle-resistant – One of the key advantages of polyester is its ability to maintain a smooth, wrinkle-free look without constant ironing.
Moisture-wicking – Unlike natural fabrics such as cotton, polyester quickly draws moisture away from the skin, keeping you dry during physical activities.
Shrink and stretch resistance – Polyester holds its shape well, even after frequent washing and wear.
Cost-effective – It’s a budget-friendly option for businesses looking to produce durable, high-quality garments.
Cons
Breathability – Polyester can feel less breathable than natural fibers, which may cause discomfort in hot climates.
Texture – Wondering what does polyester feel like? Some people find it less soft compared to cotton or rayon.
Odor retention – Polyester tends to trap odors, which can be an issue in activewear unless treated for odor resistance.
Environmental concerns – Polyester is made from petroleum-based materials, raising sustainability concerns despite advancements in recycling techniques.
Does polyester stretch?
100% polyester isn’t inherently stretchy. It has some flexibility but lacks the elastic properties of fibers like spandex or elastane. Blending polyester with these fibers creates fabrics with good stretch and recovery – ideal for activewear or fitted garments.
Factors that affect polyester stretchability
There are several factors that affect how stretchy polyester is, including the type of polyester, the weaving method, and the fabric thickness.
Material combinations like a poly-cotton blend offer greater elasticity and comfort, while a plain weave tends to hold its shape and negatively affect the stretchiness of polyester.
Should you size up with 100% polyester?
Since 100% polyester has minimal stretch, we recommend sizing up for a more comfortable fit, especially in form-fitting or tight clothing.
Is polyester more stretchy than cotton?
Pure polyester is less stretchy than cotton. Polyester resists water and maintains its structure, while cotton fibers naturally absorb water and offer slight stretch over time.
However, polyester can become much more flexible than cotton when blended with elastic fibers like spandex, making it ideal for activewear and fitted garments.
How is polyester made?
Manufacturers produce polyester using two main methods – from raw materials or by recycling plastic.
Both methods create a durable, wrinkle-resistant, and versatile material that is suitable for various products, from t-shirts to pet bandanas.
Let’s take a closer look at each production method.
Polyester made from raw materials
When making polyester from scratch, the main ingredient is ethylene glycol derived from petroleum. Manufacturers react ethylene glycol with dimethyl terephthalate (DMT) or terephthalic acid (TPA) to create a monomer, which undergoes polycondensation to form a polymer.
Next, the producer melts the polymer and extrudes it to form long strands, which are then cut into small PET pellets.
Operators melt and push these pellets through a machine like an oversized sieve to create large threads. Once they cool down, they’re twisted together to make polyester yarn.
Polyester made from recycled plastic
Recycled polyester production begins with collecting used plastic items like bottles. Manufacturers sort these items into clear and dyed plastic, then wash them to remove all contaminants.
After sorting, they clean and dry the plastic thoroughly to make sure it’s free from impurities.
The process continues with melting and extrusions, just like in the previous method.
This recycling technique not only reduces plastic waste but also produces a versatile and durable fabric suitable for various applications, from clothing to home goods.
Different types of polyester blend fabrics
Not all poly-blends are equal, as each has a specific purpose. Some polyester fabrics are meant to be durable and water-resistant. Others need to be stretchy so the wearer can move comfortably.
Combining polyester with both natural and synthetic materials enhances its properties.
Let’s take a closer look at the three most common types of polyester blend fabrics.
Polyester-cotton blends
A polyester-cotton blend is one of the most popular materials in apparel manufacturing. Since this type of knitted polyester fabric is only slightly stretchy, it’s mainly suitable for everyday, low-performance activities.
These polyester-cotton fabrics combine the advantages of polyester, like durability and wrinkle resistance, with cotton’s natural softness and breathability.
Perfect for everyday t-shirts and casual wear, poly-cotton blends are a versatile choice for people looking for comfort without compromising on quality.
If you want your polyester clothing to feature the best of synthetic and natural materials, we recommend poly-cotton blends.

Polyester and spandex or elastane blends
Most designers will agree that adding spandex or elastane to polyester greatly enhances its flexibility, making it ideal for garments that demand stretch.
If you’re curious about what does polyester feel like when blended with spandex – it’s smooth, lightweight, and perfect for sportswear, swimwear, and leggings.
While polyester offers moisture-wicking properties to keep the wearer dry, spandex and elastane make sure the fabric retains its shape even after repeated stretching.
Altogether, it’s the perfect combo for cozy days at home or hardcore sessions at the gym.
A little goes a long way with spandex and elastane – you only need a bit to make polyester stretchy. Even adding 10% of elastane can stretch the whole fabric to almost double its size.

Triblends
This blended fabric uses three materials – cotton, polyester, and rayon.
Rayon, or viscose, is a semi-synthetic fiber manufactured from both human-made and natural materials, like cellulose derived from wood and other plant fibers.
It's lightweight, breathable, and moisture-absorbent, but it’s the soft texture and the way it drapes that creates its unique feel.
Combined with the strength of polyester and the comfort of cotton, this fiber trio creates exceptionally comfortable garments.

Does polyester stretch out or shrink after washing?
Polyester fibers are incredibly durable – regular washing, even in warm water, doesn’t harm 100% polyester fabrics.
It’s essentially plastic, so as long as you keep it away from very high temperatures, it’ll survive heavy use.
However, polyester blends can lose shape over time without proper care, so make sure to follow the washing instructions of your polyester garment.
All of Printify’s indoor and outdoor clothing has detailed care instructions in product descriptions, so your customers can enjoy their garments for many years.
Printing on polyester or natural fabrics
Both the printing method and fabric you choose as the canvas for your designs significantly impact the color vibrancy and durability.
Synthetic and natural fibers absorb dyes in very distinct ways, affecting how well the artwork holds up over time.
Check out our list of the best t-shirts for printing to make sure your designs last after wash and wear.
Direct-to-garment printing
It's one of the top printing methods for custom t-shirts and other product types in Print On Demand to bring colorful and detailed designs to life.
These prints generally use water-based inks. Meanwhile, one of the properties of 100% polyester is being water-resistant.
This doesn’t mean that your artwork won’t stick to a polyester garment. The fabric just needs pretreatment to allow the ink to bond effectively.
It’s best to choose light-colored polyester garments for printing to make the design as vibrant as possible.
As an alternative, we have natural fibers that are water-absorbent by default. Cotton is the number one choice for printing with water-based inks as it fully absorbs them.
Sublimation printing
When printing on a polyester material, sublimation is the ideal technique. Unlike natural fibers, polyester absorbs sublimation ink seamlessly, creating vibrant and long-lasting designs. This highlights one of the key benefits of polyester – it bonds well with dye for bright, fade-resistant prints.
What other types of plastic fibers are there?
Synthetic fabrics have changed the game, making it easy to create durable, weatherproof, soft, and elastic garments.
Each fiber offers its own set of advantages, suitable for different types of clothing, home goods, and industrial products.
Let’s look at three of the most popular synthetic fibers and their characteristics.
Nylon
Nylon was the first synthetic fabric to reach mass production. It’s also one of the most versatile materials to make products ranging from apparel and upholstery to seat belts.
This durable fiber makes a very elastic fabric, is resistant to wrinkles, and shows remarkable resilience.
