1. The principle of water repellent umbrella cloth

Waterproof umbrella fabric is mainly achieved through special surface treatment to achieve waterproof function. The fibers on the surface of the umbrella cloth are chemically treated to reduce the tension on the fiber surface. When raindrops come into contact with the umbrella cloth, due to the difference in surface tension, they will form water droplets instead of penetrating into the umbrella cloth. This principle is similar to the lotus leaf effect, where there is a layer of wax crystals on the surface of the lotus leaf, and water forms droplets rolling on the lotus leaf without wetting it.

Some waterproof umbrella fabrics also use coating methods, such as applying a layer of fluoride coating on the outer layer of the umbrella fabric. This coating can fill the tiny pores between fibers, further preventing the penetration of moisture, while also enhancing the water repellent performance of the umbrella fabric.

2. Material of water repellent umbrella cloth

Polyester fiber (PET)

Polyester fiber is a commonly used waterproof umbrella fabric material. It has high strength and wear resistance, and can withstand a certain degree of tension and friction without being easily damaged. Moreover, polyester fibers have good chemical stability and excellent waterproof performance after water repellent treatment. For example, many high-quality outdoor waterproof umbrellas use polyester fiber as the umbrella fabric material, which can effectively block rainwater in heavy rain environments and is durable.

Nylon

The characteristics of nylon material are high strength and good toughness. When used for waterproof umbrella cloth, it can be woven very finely, effectively preventing rainwater from penetrating. Nylon umbrella cloth also has good elasticity, which can maintain the shape of the umbrella cloth well during folding and unfolding. Some high-end folding waterproof umbrellas use nylon material and add a waterproof coating on the surface of the nylon umbrella cloth to make its waterproof performance even better.

Coated fabric

In addition to the fluoride coating mentioned above, some coating fabrics also use polyurethane (PU) coating. PU coating can not only improve the water repellent performance of umbrella fabric, but also enhance its tear resistance to a certain extent. This type of waterproof umbrella made of coated fabric is also quite common in the market, especially in some demanding outdoor scenarios such as hiking and mountaineering.

3. The advantages of waterproof umbrella cloth

Good waterproof performance

The utility model can effectively prevent rainwater infiltration, and can ensure that the users under the umbrella stay dry and cool even in the case of long-term rainfall or rainstorm. This is the main advantage of waterproof umbrella cloth, which can provide more reliable rain protection compared to ordinary umbrella cloth.

Easy to dry

Due to the formation of water droplets on the surface of the umbrella cloth by rainwater, the umbrella cloth can dry quickly after shaking the water droplets. This is very convenient for users who frequently use umbrellas, as there will be no problems such as mold growth caused by prolonged moisture on the umbrella cloth.

Enhanced durability

Water repellent umbrella cloth is usually made of fine materials or surface treatments, which gives the umbrella cloth good wear and tear resistance. In daily use or complex outdoor environments, umbrellas can better withstand various external forces and extend their service life.

4. Application scenarios of waterproof umbrella cloth

Daily commuting

In daily activities such as commuting or shopping in the city, the waterproof performance of waterproof umbrella cloth can effectively cope with sudden rainy weather. And its easy to dry feature makes it convenient for users to quickly put away umbrellas after entering the room, without wetting the ground or other items.

Outdoor travel and sports

During outdoor activities such as hiking, trekking, and camping, the weather is constantly changing and heavy rain may be encountered. Waterproof umbrellas made of waterproof fabric can provide reliable rainproof measures for travelers, ensuring the dryness of their bodies, backpacks, and other items. Meanwhile, its durability can also adapt to complex outdoor terrain and environments.
