Waterproofing in textiles: innovation and expertise at Finipur
Waterproofing textiles and other flexible materials is crucial for variety of applications and various sectors, from sportswear to construction and industrial applications. At Finipur, experts in textile finishing, we offer high-quality techniques for waterproofing materials. This can be done either through the application of coatings on our various machine lines or through the technique of laminating where we will adhere a membrane or film to the customer's substrate. Each of these methods has its own distinctive advantages and applications, depending on the specific requirements of the project. Read all about it in this article and contact us to discuss your project or questions.
Waterproof coatings: functionality and versatility
Coating involves applying a protective or opaque coating consistently over the surface of the material to be treated. This coating can not only make the textile waterproof, but if required for certain applications, we at Finipur can also add additional properties such as:
- Antibacterial: ideal for beds and medical applications.
- Flame retardant: suitable for upholstery fabrics and building materials.
- Wear and chemical resistance: Important in industrial applications.
- Moisture permeability: In the sports world, but also in building applications, the end product may need to be waterproof in one direction, but breathable and/or moisture-permeable in the other. Think of building cladding or sportswear.
- UV resistance: We can add additives in the coating to make the final product more resistant to the effects of UV light exposure
For coatings, acrylates and polyurethanes are often used, both known for their exceptional performance and durability. Which chemistry we will ultimately apply depends on factors such as the type of fabric (is it an open or closed structure) and the desired end-use properties.
Waterproofing through laminating: the highest standard in waterproofing
Laminating is done by attaching or adhering a membrane or film to the textile. This process results in superior waterproofing, tested using the rigorous water column test, which measures how well a material can withstand water pressure. So here we can glue one particular membrane against the substrate to be treated or even multi-layered structure.
The stringent requirements apply to applications such as:
- Sportswear: Protection from rain and wind without losing breathability.
- Building materials: Waterproof layers for roof structures and cladding.
- Upholstery fabrics : Ideal for outdoor furniture and other demanding environments.
Laminating is particularly suitable for applications requiring an exceptionally high degree of water resistance.
