As with all industries, sustainability is a new trend. So when it comes to trend forecasting, designers are always looking for new ways to stay ahead of the curve. One way that is being explored to create garments with a more sustainable footprint is polyurethane.

Polyurethane can be applied to fabric in liquid form to create a layer that will give it water-repellent properties.

Waterborne polyurethane For Coating Leather Goods

Leather rarely goes out of fashion in the industry, and when it does, it is always because of practical considerations. For instance, if a leather product gets wet—from getting caught in a rainstorm or sweat—the product can begin to break down.

The leather becomes softer and more porous, decreasing its water resistance, making it vulnerable to water-based stains. Water-repellant polyurethane coatings improve the resistance of leather against these types of wear-related deteriorations. This makes it an excellent choice for various leather products, including bags, shoes, jackets, belts, and more. The polyurethane forms a thin protective layer on top of the leather that resists water while allowing for breathability. This allows the leather to retain its natural look while giving it enhanced waterproof and stain-resistant properties.

All polyurethanes are not alike! A major factor to consider when choosing between polyurethane products is whether the product you are using is waterborne or solvent-based.

Waterborne Polyurethane For Shoes As Resin

Most footwear on the market today has a combination of different materials. One example is the rubber sole beneath a leather or synthetic upper. This type of footwear is in danger of becoming more porous due to water and sweat, which can cause deterioration to both the upper and the outsole.

A liquid polyurethane coating applied to leather protects it from water, stains, and dirt while keeping it breathable. Additionally, it adds a shine to the product—making it more appealing to the consumer.

 A Vegan Alternative

As the demand for sustainable fashion increases, there is increasing pressure to use only naturally derived materials. Many people who choose to avoid leather footwear will turn to other materials like synthetic materials or fabrics.

Influencers advocate for polyurethane goods as a vegan alternative to leather because it’s manufactured, water-repellant, and can be used for various products. As a non-animal based product, it is an excellent alternative to traditional leather goods.
