The elements can take a considerable toll on outdoor fabrics. High temperatures, UV exposure, and moisture cause many materials to fade, discolour, or disintegrate — often within a single season. Solution-dyed acrylic was developed specifically to address this problem. It's a high-performance synthetic fabric known for exceptional durability and colourfastness, and it's the material we use in our Portsea pool bean bags.
What Is Solution-Dyed Acrylic?
Acrylic fabrics are durable synthetic fabrics made from acrylic fibres. They're mildew-resistant, moisture-managing, and strong — a solid baseline for outdoor use. What makes solution-dyed acrylic exceptional is how the colour is applied.
In standard dyeing processes, colour is applied to the surface of finished fibres. In solution dyeing, the dye is added to the liquid acrylic polymer before the fibres are spun — meaning colour permeates the entire fibre from the inside out. The result is a fabric where the colour is part of the material itself rather than a coating on top of it. For more on outdoor fabric options, see our complete bean bag fabrics guide.
Piece-Dyed vs Solution-Dyed — What's the Difference?
Acrylic fibres begin as a liquid polymer solution. The chemical fluid is forced through a device called a spinneret — a plate with many tiny holes — which extrudes long acrylic fibres. Without added dye, those fibres emerge white.
In piece-dyed (or "stock-dyed") fabrics, the extruded fibres are dipped into a vat of dye after they're made. The dye penetrates only the outer surface of each thread; the interior stays white. This method produces bright tones efficiently and allows manufacturers to produce small batches in many colours — it's how most synthetic textiles and carpets are dyed.
Solution-dyed fibres are coloured differently. The dye is added to the chemical solution before it enters the spinneret, so the extruded fibres have colour mixed throughout — not just on the surface but all the way through.
The easiest way to understand the difference is the carrot and radish comparison. Cut a radish open and the inside is white despite the bright red skin. Cut a carrot and it's orange to its core. Solution-dyed fabric is the carrot — colour all the way through, not just on the surface.
How Solution-Dyed Acrylic Performs
Because colour saturates each fibre entirely, it's extremely difficult to fade or bleach away. Solution-dyed acrylic fabrics are among the most colourfast in the textile industry. In practice this means:
- UV resistance — sustained sun exposure that would fade a piece-dyed fabric has minimal effect on solution-dyed acrylic
- Chlorine resistance — you can clean solution-dyed acrylic with diluted bleach without affecting the colour, making it suitable for pool and healthcare environments
- Mildew resistance — the fabric resists mould and mildew growth, which is critical for anything used near water
- Colour longevity — solution-dyed fabrics maintain their vibrancy season after season where surface-dyed alternatives would fade significantly
In the past, solution-dyed fabrics were considered less vibrant than yarn-dyed alternatives. That's no longer the case — modern solution-dyed acrylics are rich and vivid enough to rival the brightest surface-coloured options.

Care and Maintenance
Solution-dyed acrylic is low-maintenance by design. For everyday cleaning, brush off loose dirt and debris, then rinse with clean water. For stubborn stains, a mild soap solution and a soft brush or cloth are sufficient — rinse thoroughly and allow to air dry.
For tougher stains, diluted bleach can be used without risk of colour damage — a meaningful advantage over most other outdoor fabrics where bleach would strip colour immediately. In commercial settings with heavy use and frequent spills, routine cleaning prevents mildew buildup and extends the fabric's life. Periodically check for signs of wear and address them promptly.

Why We Use It in Our Pool Bean Bags
Pool bean bags face a specific set of demands: chlorinated water, saltwater, direct sun, repeated wetting and drying, and heavy use from multiple users. We chose solution-dyed acrylic for our Portsea pool bean bags because it handles all of these without compromise. The specific benefits in a pool setting:
- Durable and long-lasting even with frequent direct sun exposure
- Quick-drying after use, which reduces the chance of mildew or mould growth
- Strong enough to handle the weight of adults while remaining comfortable to lie on
- Colourfast — the vibrant colours stay vibrant, season after season
We also offer Piedra, a specific outdoor fabric featuring a grey and white stripe pattern. Piedra is highly durable, water-resistant, and provides UV protection — suitable for outdoor furnishings including blinds, awnings, and cushions.
