we are industry
With the improvement of people's living standards and environmental awareness, the demand for sun protection is also increasing. In modern society, people are paying more and more attention to sunscreen products with anti-ultraviolet effect, and coated fabrics are a new kind of sunscreen materials. Coated fabrics are used as a primary material to develop sunscreen products, and it has several advantages, including its anti-UV effect. So how is the UV protection effect of the coated fabric? The following article will discuss the anti-ultraviolet effect of coated fabric from the definition of coated fabric, the preparation of coated fabric and the anti-ultraviolet effect of coated fabric.
First, the definition of coated fabrics
Coated fabric is a relatively emerging sunscreen material, which refers to the specific ingredients coated on a certain material to make it have a good anti-ultraviolet effect. The components of the coated fabric include polyurethane, silicone, charcoal fiber, etc., which can be used to make clothing, sports goods, sunscreen products, etc. These coating materials contain a certain amount of chemicals that can absorb and reflect ultraviolet light.
Second, the preparation of coated fabric
The preparation of coated fabric has certain technical difficulties, and it is necessary to conduct in-depth research on the type and use of coated materials. The preparation process of coated fabric mainly includes the following steps:
1, screening coating materials: screen out good durability, harmless to the skin, excellent anti-ultraviolet coating materials, select the appropriate coating components.
2, choose the appropriate coating technology: the common coating technology includes suspension coating, spray coating, hot press coating, etc., but according to the specific needs to choose which coating technology.
3, coating: After completing the necessary coating technology preparation, coating is carried out to complete the processing and preparation of the coating material.
Third, the anti-ultraviolet effect of the coated fabric
1. Absorptive protection of coated fabrics: After adding certain chemical components to coated fabrics, ultraviolet rays can be absorbed and converted into other forms of energy. When ultraviolet light passes through the coating material, the chemical composition of the coating material will absorb some of the ultraviolet light, so as to achieve a certain sunscreen effect.
2. Reflective protection of coated fabrics: Materials such as charcoal fibers in coated fabrics have strong reflective properties, and after special treatment, some ultraviolet rays can be reflected back, thus playing a role in sunscreen.
3, the shielding protection of the coated fabric: the coated fabric also has a certain shielding performance, which can block the direct exposure of sunlight to the skin surface. Especially in outdoor sports, the shielding performance of the coated fabric can bring people a good sunscreen effect.
In short, the anti-ultraviolet effect of the coated fabric is relatively stable, and it has three ways of protection, reflection and shielding, so it has a good sunscreen effect. As a new material, coated fabrics can be widely used in sunscreen products. However, it should be noted that the coated fabric also has certain preparation cost requirements, so the price of the product is relatively high.
