Drop of water on 100% polyester textile. Waterproof/breathable fabrics resist liquid water passing through, but allow water vapour to pass through. Their ability to block out rain and snow while allowing vapour from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing, tents, and other applications.
Rain tyres have a specially designed structure making them better adapted for their application than any other tyres. However, not all rain tyres obey the same design principles. Certain factors need to be taken into account when designing a good rain tyre, such as the: Speed of the car; Weight of the car; Power of the car; Lifespan of the tyre
Durable water repellent is a type of fabric coating to protect them from water. In addition, superhydrophobic coatings have potential uses in vehicle windshields to prevent rain droplets from clinging to the glass, to improve driving visibility. Rain repellent sprays are commercially available for car windshields. [14] [15]
Cars, and buses have a large use of automotive textiles. A car can consume up to 25 kg of fabric, primarily used for roof coverings and upholstery.Automotive textiles also used in interior trimmings, seats, side panels, carpets, and car trunk coverings, linings, tires, filters, belts, hoses, airbags, etc. [4]
The system when used on cars provided quieter travel, and improved performance because of the body's light weight; but gave little protection in the event of a serious accident, and without care (the materials being prone to rot), a potentially short life. Fabric provided a matt surface and the framework sharp corners.
Two fabrics may have a B1 of 10,000gr, but one can be 10,000 A1 and the other 4,000 A1. It all depends on the type of coating or lamination and how it moves moisture. Typically hydrophobic coatings perform better than hydrophilic laminations on the Ret and A1 Test. And vice versa, the hydrophilic laminations will perform better on the B1 test.

A garment described as waterproof will have a water-repellent coating, with the seams also taped to prevent water ingress there. Better waterproof garments have a membrane lining designed to keep water out but allow trapped moisture to escape ("breathability")—a totally waterproof garment would retain body sweat and become clammy. Waterproof ...
