In the Print-on-Demand (POD) industry, the quality of a t-shirt doesn’t solely depend on printing techniques or designs but is also directly influenced by the fabric used. Among fabric options, polyester and cotton are the two most popular choices. But which fabric polyester or cotton is most suitable for sellers? How can you make the best decision for your business objectives? Let’s explore in detail the advantages and disadvantages of each fabric with FlashShip, so you can make the right decision, optimize product quality, and maximize your business profitability.
Overview of Polyester
1. Origins and Characteristics of Polyester Fabric
Polyester is a synthetic fabric produced through a chemical reaction between acid and alcohol, primarily derived from petroleum. Its full chemical name is polyethylene terephthalate (PET) the same type of plastic commonly used to make water bottles. Through a complex chemical process called polymerization, small molecules (monomers) link together to form long chains (polymers), which are then melted, spun into fibers, and woven into fabric.
Introduced in the 1940s, polyester quickly sparked a revolution in the fashion industry thanks to its outstanding properties, which natural fibers do not possess. For the POD industry specifically, polyester opened new horizons for printing capabilities, particularly with sublimation printing technology
2. Outstanding Advantages of Polyester Fabric for POD Sellers
- Sublimation Printing Capability: This is the most valuable advantage of polyester. Under high heat, polyester fibers “open,” allowing sublimation ink (oil-based ink) to transform from a solid to a gaseous state and deeply penetrate the fabric fibers. Once cooled, the fibers “close,” permanently locking the ink molecules within.
- Result: Prints are vividly colored, sharp down to the smallest details, with no color limitations. Since the ink penetrates the fabric, it doesn’t create a thick or rough layer on the surface. You can crumple, stretch, or wash the fabric without worrying about the print cracking, peeling, or fading.
- High Durability: Polyester fabric is extremely durable. Its polymer fibers have tightly linked molecules, effectively resisting shrinkage, stretching, and abrasion. A polyester shirt maintains its original shape even after hundreds of washes, boosting customer satisfaction and minimizing product quality complaints.
- Wrinkle-Resistance: This is a major benefit in e-commerce operations. Polyester t-shirts are less prone to wrinkles during FlashShip’s packing and shipping processes, ensuring that products arrive to customers looking neat and professional without needing ironing.
- Water Resistance and Moisture-Wicking Capability: Unlike cotton, which absorbs sweat, polyester fibers tend to push moisture to the fabric’s surface, allowing rapid evaporation. This characteristic makes polyester the number one choice for sportswear and athleisure clothing—highly promising niches within the POD industry.
- Competitive Base Price: Generally, 100% polyester blank shirts tend to be cheaper than high-quality 100% cotton shirts (such as ringspun cotton). This enables POD sellers to optimize their profit margins effectively.
3. Disadvantages of Polyester Fabric
- Less Natural Feel: Compared to cotton, polyester feels less soft and has a more “plastic” touch. This can be a downside for customers prioritizing absolute comfort and softness.
- Poorer Breathability: Due to its water-resistant nature, polyester doesn’t “breathe” as well as cotton. In hot and humid climates like Vietnam, wearing a 100% polyester shirt can feel stuffy or uncomfortable if not used specifically for physical activities.
- Retains Body Odor: This is an inherent disadvantage. Odor-causing bacteria tend to thrive more easily on polyester fibers compared to cotton fibers. Thus, polyester shirts may retain sweat odors after physical activities.
- Printing Technique Limitations: While polyester is the “king” of sublimation printing, it’s the “enemy” of Direct to Garment (DTG) printing. Water-based DTG inks can’t adhere well to polyester’s hydrophobic fibers, resulting in pale colors and easy peeling.
Overview of Cotton
1. Origin
Cotton fabric is made from natural cotton fibers that grow around the seeds of cotton plants. After harvesting, cotton bolls are processed to remove seeds and impurities before spinning into yarn and weaving into fabric. Cotton is one of the most important crops worldwide, forming the backbone of the global textile industry.
For POD sellers, understanding different types of cotton is crucial:
- Standard Cotton: The most basic type, featuring shorter fibers and a somewhat rougher texture, typically used for low-cost products.
- Ringspun Cotton: A valuable upgrade from standard cotton. Fibers are continuously twisted and thinned, producing longer, softer, and stronger threads. Shirts made from ringspun cotton have a smoother surface, a premium feel, and yield sharper results with DTG printing.
- Combed Cotton: An even higher-grade processing method in which cotton fibers are combed to remove short fibers and impurities before spinning. The result is an exceptionally soft, smooth, and durable fabric. Combed and ringspun cotton is considered the gold standard for premium POD fashion brands.
2. Advantages
- Soft and Premium Feel: This is the primary reason customers love cotton. Its natural softness against the skin creates comfort and luxury. If you’re building a streetwear or premium product line, cotton is an irreplaceable choice.
- Direct-to-Garment (DTG) Printing: Cotton is an ideal surface for DTG printing. Cotton fibers absorb water-based inks exceptionally well, allowing deep penetration into the fabric, resulting in detailed, multi-colored prints that feel soft without adding bulk. Most major POD service providers use DTG as the main printing technology for cotton shirts.
- Excellent Breathability: Cotton fibers allow air to circulate freely, helping to keep the body cool. This makes it the perfect choice for daily wear, especially in hot climates.
- Hypoallergenic: As a natural fiber, cotton rarely irritates the skin, making it suitable even for customers with sensitive skin or children.
3. Disadvantages
- Wrinkling and Shrinking: Cotton fabrics tend to wrinkle and may shrink after the first wash if not pre-shrunk. This requires users to be more careful during laundering.
- Absorbs Sweat (but Dries Slowly): Cotton absorbs moisture well, but retains it for a prolonged period. When a cotton shirt becomes drenched in sweat, it can feel heavy, cling to the skin, and take a long time to dry, causing discomfort. Thus, cotton isn’t ideal for specialized sportswear.
- Color May Fade: Over time and after repeated washing, colors on both the fabric and printed designs may fade slightly, especially if exposed to intense sunlight.
- Higher Price (For Premium Types): High-quality blank shirts made from 100%
Detailed Comparison: Polyester And Cotton Fabrics
To help you make the most informed decision, FlashShip has compiled a detailed comparison chart highlighting the key criteria that matter most to POD sellers.
| Criteria | 100% Polyester Fabric | 100% Cotton Fabric | Insights for POD Sellers |
| Feel & Comfort | Slightly slippery, lightweight, occasionally “plastic” feel. | Soft, natural, gentle against the skin. | Insight: Cotton wins for premium comfort. Highlight “soft 100% ringspun cotton” in product descriptions if you’re selling cotton shirts. For polyester, emphasize features like “lightweight, stretchy, ideal for activewear.” |
| Durability & Shape Retention | Extremely durable, shrink-resistant, wrinkle-resistant, maintains shape well. | Less durable, prone to shrinking and wrinkling after washing. | Insight: Polyester ensures long-term customer satisfaction due to shape retention—use the selling point “maintains shape even after multiple washes.” For cotton, prioritize pre-shrunk products. |
| Breathability | Poor breathability; may feel stuffy. | Highly breathable and cool. | Insight: Cotton is suitable for everyday fashion, especially in hot climates. Polyester is ideal for sweat-intensive activities where moisture-wicking outweighs breathability. |
| Moisture-Wicking | Excellent; pushes sweat outward and dries quickly. | Poor; absorbs sweat and retains moisture longer. | Insight: This is critical for sportswear niches. If selling clothing for gym, running, yoga, etc., choose polyester and heavily promote the “moisture-wicking” feature. |
| Ideal Printing Techniques | Sublimation: Vibrant, permanently durable colors, ideal for All-Over Prints (AOP). | Direct-to-Garment (DTG): Beautiful colors, highly detailed, soft to the touch. | Insight: This is the most important criterion. Your design determines the fabric choice. For vibrant, full-print designs, select a POD provider offering sublimation printing on polyester. For detailed, multi-colored designs typically placed on the chest, DTG printing on cotton is optimal. |
| Care & Maintenance | Easy-care, wrinkle-resistant, fast-drying. | Requires more careful handling, wrinkles easily, ironing necessary. | Insight: Polyester’s easy-care characteristic is a strong selling point for convenience. |
| Cost of Blank Products | Typically less expensive. | More expensive for high-quality types. | Insight: Polyester can offer higher profit margins per product. However, premium cotton shirts can command higher prices to offset the cost. |
| Environmental Impact | Petroleum-based, non-biodegradable, recyclable. | Natural fiber, biodegradable, but cultivation requires large amounts of water and pesticides. | Insight: Both fabrics have environmental pros and cons. If your brand promotes sustainability, explore options like recycled polyester or organic cotton. This is a powerful marketing angle. |
Ultimately, each fabric has unique advantages and disadvantages. The right choice depends on your intended use and target market.
Should You Choose Blended Fabrics (Poly-Cotton)?
After analyzing two opposite extremes, a natural question arises: Is there a middle ground solution that combines the advantages of both fabrics? The answer is yes and that solution is poly-cotton blends.
