When you purchase bulk custom apparel, gloves, or hats, you must understand material properties regarding ink penetration, price points, and user comfort. We broke down the differences to help you sign that purchase order with confidence.
At a Glance: The Quick Decision Guide
Short on time? Here is the essential breakdown for merchandise managers deciding between these two sustainable heavyweights:
- For Premium Retail Feel: Organic cotton wins. The material provides a pleasant touch experience and dense weight, creating an upscale atmosphere that promotes relaxation.
- For Performance & Outdoors: Recycled polyester is the functional choice. It wicks moisture while keeping its original color vibrant, even after prolonged exposure to sunlight.
- For Printing Detail: Organic cotton is superior for intricate designs using water-based inks, which sink into the fiber for a “soft hand.”
- For Budget at Scale: Recycled polyester (rPET) often wins on unit cost for massive orders due to established recycling supply chains.
Printing Compatibility: Ink vs. Fiber
Your design is only as good as the canvas. The two fabrics need separate operational methods because they respond differently to decoration techniques.
Screen Printing on Organic Cotton
Organic cotton is a natural cellulose fiber. It demonstrates excellent absorption of water-based inks, producing a “soft hand” texture where the design feels like an integral part of the shirt rather than a plastic sticker. According to the Global Organic Textile Standard (GOTS), certified goods must use inputs that meet strict toxicity and biodegradability rules, which often align perfectly with high-quality water-based discharge printing. It maintains integrity through oven curing temperatures without scorching.
Decorating Recycled Polyester
Polyester is essentially a plastic substance. Standard inks stay on top of the fibers rather than absorbing into them. This allows for vibrant color schemes that match the visual identity of athletic teams. However, you must watch out for dye migration. This occurs when the dye from the fabric bleeds into the ink during heating (e.g., turning white ink pink on a red shirt). Special low-bleed blockers are required.
Achieving a vintage washed-out look is difficult on polyester. However, if you require all-over sublimation printing, recycled polyester is your only option. Sublimation requires synthetic polymers to bond with the ink; you cannot sublimate effectively on 100% cotton.
The Cost Equation: Margins and Perceived Value
Users need to check both weight measurements and product origins when performing the Organic Cotton vs. Recycled Polyester comparison.
Organic Cotton T Shirts
Expect a higher base unit cost. Organic farming forbids synthetic pesticides and fertilizers, which can result in lower yields per acre compared to conventional intensive farming. You are paying for the certification (like GOTS or OCS) and the fair labor standards often attached to these supply chains. The ROI comes from customer perception: clients and employees generally view organic cotton t shirts as a “premium” gift with higher perceived value.
Recycled Polyester
This material is made from melted-down plastic (often PET bottles). The supply chain for polyester recycling operates at a high level of efficiency. According to Textile Exchange, recycled polyester now owns a significant share of the synthetic market, driving down production expenses. For a 5,000-unit trade show order, rPET can significantly reduce costs while still allowing you to add “Made from Recycled Bottles” to your marketing claims.
Durability and End-Use
Who is wearing this gear? If you are outfitting a sales team that sits in air-conditioned offices, organic cotton is breathable, comfortable, and manages odor naturally.
However, organic cotton absorbs sweat, which can create heavy, wet conditions for warehouse staff or outdoor event personnel. The functional winner here is recycled polyester. It offers three main benefits: it stays flat, resists shrinking, and has high tear strength. For sourcing different material types, refer to our sourcing guide for apparel.
Common Procurement Pitfalls
Even experienced buyers can make errors when switching materials. Avoid these common mistakes:
- Unexpected Shrinkage: Organic cotton is typically not treated with formaldehyde-based anti-shrink resins used in conventional cotton. Expect it to shrink more (often 5-10%) if not pre-washed/compacted.
- The “Heat Press Box”: When ordering heat-transfer logos on polyester, ensure your supplier uses the correct temperature and pressure. Incorrect application can leave a permanent shiny square “press box” mark on the fabric.
- End-of-Life Reality: A shirt that is 50% organic cotton and 50% recycled polyester is great for comfort, but it is currently difficult to recycle. Separating blended fibers is cost-prohibitive compared to mono-material recycling.

Making the Final Call
Organic cotton fabric provides an upscale texture best suited for corporate retreats and high-end client gift presentations. For active workwear or massive trade show handouts, the durability and price point of recycled polyester make sense.

Frequently Asked Questions
Is organic cotton better for screen printing than recycled polyester?
Generally, yes. Organic cotton absorbs water-based inks effectively, resulting in a softer feel and a longer-lasting print that does not crack easily. Polyester often requires plastisol inks and special blockers to prevent dye migration.
Which fabric is cheaper: organic cotton or recycled polyester?
Recycled polyester is typically cheaper per unit for bulk orders due to efficient recycling supply chains. Organic cotton usually carries a premium price reflecting the lower crop yields and strict certification costs associated with organic farming.
Does recycled polyester shrink in the dryer?
Recycled polyester is very resistant to shrinkage and holds its shape well. In contrast, organic cotton can shrink significantly (5-10%) if it has not been pre-shrunk, as organic standards often restrict the use of chemical anti-shrink agents.
Can you sublimate on organic cotton?
No. Sublimation printing works by chemically bonding ink to synthetic polymers under heat. It requires a high polyester content (usually at least 65%) to hold the image; cotton fibers cannot bond with sublimation dye.
