Have you ever wondered why polyester sweat blankets often tend to build up static, while blankets made from natural materials like wool or cotton don't? The answer lies in the material's properties and its ability to wick moisture. Here's why polyester gets static and why natural fibers avoid this problem.
Polyester – Why static charge?
Polyester is light, durable and dries quickly, but these advantages also have disadvantages: Polyester has low moisture absorption and does not conduct electrical charge. When a polyester blanket is on the horse and friction is created by movement, static electricity is generated. Since polyester does not absorb moisture, the electrical charge cannot escape and accumulates in the blanket. This effect is particularly pronounced in dry, cool environments - the "crackling" and small electric shocks can be unpleasant for horse and rider.
Wool and Cotton – The Natural Alternative
Wool and cotton are natural materials with special properties: they are hygroscopic, which means they can absorb moisture from the environment or from the horse's coat. This moisture absorption is the key to why wool and cotton do not build up static charge.
Moisture absorption and dissipation of electrical charge
Natural fibers such as wool and cotton absorb moisture and can disperse and dissipate electrical charges. When the horse sweats or the air is humid, the fibers absorb this moisture, preventing static electricity from building up. The moisture absorption neutralizes electrical charges, preventing crackling and small electric shocks.
More comfort for the horse
Sweat blankets made of wool or cotton are often more comfortable for the horse. They wick moisture away from the coat, keep the horse dry and avoid the unpleasant "crackling" and small electric shocks that can occur with synthetic blankets made of polyester. This is a great advantage, especially for sensitive horses, because they remain relaxed and feel more comfortable.
Conclusion
The static charge of polyester blankets is caused by a lack of moisture absorption and poor conductivity. Wool and cotton, on the other hand, absorb moisture and conduct electrical charges, thus preventing static charge. If you are looking for a comfortable sweat blanket for your horse that does not crackle and is pleasant to wear, natural materials such as wool and cotton are the optimal choice.
