What is Polyester?
Polyester is a synthetic fabric created through chemical processes – essentially a plastic fibre. When used in home & garden products like parasols and outdoor clothing, it indicates the material is primarily made from polyester threads. This generally means good resistance to water and fading compared to natural fibres, making it suitable for outdoor use. However, polyester can be less breathable than cotton and may require specific cleaning methods. It’s often a more economical choice than some other fabrics, but its durability can vary depending on the weave and thickness of the material.
Polyester’s widespread use in outdoor home & garden products stems from its unique properties, largely derived from being a thermoplastic polymer. Unlike natural fibres like cotton or wool, polyester is created through a process involving reacting petroleum-based chemicals – this gives it exceptional durability and resistance to degradation. You can often gauge the quality of polyester by observing its ‘hand’; a higher grade will feel smoother and less prone to pilling, though this isn’t always a reliable indicator, especially with cheaper outdoor cushions or parasol covers. Many products utilize a blend of polyester with other fibres like cotton or acrylic to improve comfort or reduce cost; check the product description for exact percentages.
UK shoppers sometimes mistakenly assume all polyester is created equal – weaves significantly impact performance. A tightly woven polyester will offer greater UV resistance and water repellency, vital for parasols and outdoor furniture upholstery. Look for terms like ‘ripstop’ polyester, which is designed to prevent tears from spreading; this is particularly useful in tents or awning covers. It's also worth noting that polyester can be prone to static cling, especially in drier weather, so a fabric softener might help. Be mindful of washing instructions – hot water and harsh detergents can damage polyester fibres, leading to colour fading and fibre breakdown, so always follow the manufacturer’s recommendations.

FAQ
What does ‘polyester ripstop’ mean?
‘Ripstop’ polyester is woven with a reinforcing grid pattern that prevents tears from spreading. If a small tear occurs, it will typically stop at this grid line, minimising the damage and preventing further ripping; this is crucial for items like tent flysheets or awning covers where durability is paramount.
How does polyester compare to cotton in terms of weather resistance?
Polyester generally outperforms cotton in damp conditions due to its hydrophobic nature – it repels water rather than absorbing it, preventing the fibres from becoming heavy and losing their shape. Cotton will absorb moisture, leading to a longer drying time and potentially mildew growth, especially if exposed to prolonged rain.
What should I look for when checking the polyester weave?
A tighter weave provides better protection against UV rays, water penetration, and abrasion. Look for weaves described as ‘high density’ or ‘woven tightly,’ particularly in outdoor furniture cushions and parasol covers; a looser weave will be less durable.
Is polyester suitable for all outdoor uses?
While versatile, polyester isn't ideal for extremely high-heat environments. Prolonged exposure to direct sunlight at very high temperatures can cause the fibres to degrade over time, leading to reduced strength and colour fading; consider blends for demanding applications.
How does the thickness of polyester affect its performance?
Thicker polyester fabrics offer greater durability and resistance to wear and tear. When buying outdoor cushions or covers, look for a higher denier (a measurement of fibre thickness) – typically 200-400 denier is common for outdoor use.
What’s the difference between polyester and acrylic?
Both are synthetic fibres but differ in their feel and properties. Polyester tends to be more durable and resistant to UV light, whereas acrylic is softer and often used in cheaper outdoor furniture covers due to its lower cost; however, acrylic is less resistant to fading.
Can I wash polyester products at home?
Follow the manufacturer’s washing instructions carefully. Generally, cold or lukewarm water with a mild detergent is recommended; avoid using hot water or harsh chemicals which can damage the fibres and cause colour loss.
What does a ‘DWR’ coating on polyester mean?
‘DWR’ (durable water repellent) is a chemical finish applied to polyester fabrics to further enhance their water resistance. It creates a barrier that prevents water from penetrating the fibres, extending the product's lifespan and maintaining its performance.
Are there any specific brands known for high-quality polyester?
Several brands specialize in outdoor textiles utilising premium polyester blends. These often include names like Outwell and Coleman, who frequently incorporate higher denier polyesters with enhanced UV resistance – check product specifications carefully before purchasing.
What should I do if my polyester product starts to fade quickly?
Rapid fading can indicate insufficient UV protection or exposure to harsh sunlight. While some colour loss is normal over time, excessive fading suggests the material isn’t adequately shielded; consider using a parasol or awning cover to protect it from direct sun.
