Generally speaking, the shoes are slightly larger after wearing it for a long time. Do not buy more than half or one code when buying sports shoes you usually wear casual.However, such as tennis, such as tennis, moving and turning movements, it is also possible to buy a 0.5-1 code for tennis shoes.Because the blood is swollen slightly, it will be more comfortable when wearing most of them.In addition, the soles of tennis shoes are thicker, and the shoe code will increase accordingly.If you choose the usual number of code, you may feel that the shoes are tight.

What kind of fabrication of UV clothing is better

sunlight includes different bands such as visible light, ultraviolet rays (UV), and infrared. Among them, the light of 100-400 nanometer wavelength is ultraviolet rays.UV spectrals are divided into three bands of UVA, UVB, and UVC. Among them, UVA and UVB have the greatest harm to the human body. In short, UVA takes you black and causes a large amount of melanin to settle in the epidermis layer.UVB can penetrate the epidermis, and long -term exposure will cause genetic factor DNA damage, leading to Skin cancer, which accounts for 6.1%of the sunlight.

Polyester fabric clothes have the best effects, which is related to the benzene ring in the structure of polyester fiber molecules. The role of clothes such as cotton, silk, nylon, and adhesive fabrics is poor.Polyester fabrics have a good absorption and reflection effect on ultraviolet rays. They have strong shielding. The passage of ultraviolet rays is less than 3 %, and the ultraviolet prevention rate is still more than 85 %.In addition, the deeper the color, the better the resistance of UV is better. Black, hidden blue, dark green is better than ultraviolet -resistant performance than light blue, light pink, light yellow.The darker the color of the fabric, the smaller the ultraviolet transmission rate.The closer the fabric of the clothes, the stronger the lighting ability, and the less UV rays.Outline prevention of weaving fabrics is better than knitted fabrics.

The working principle of sunscreen

The principle of sunscreen is to use ultraviolet absorbers in mixed fabrics to absorb high -energy ultraviolet rays to transform it to low energy and turn into low -energy thermal energy or electromagnetic waves with short wavelengths, thereby eliminating the harm of ultraviolet rays to human and fabrics.It also uses ultraviolet reflexes to increase the reflection and scattering effects of fabrics on ultraviolet rays to prevent the fabric through fabrics.It has the performance of heatstroke, heat insulation, and cool touch.

It should be noted that the national standards stipulate that UPF & LT; 30, UVA transmission rate & gt; 5%of fabrics cannot be called sunscreen products.Sun protection clothing fabrics include fabrics such as cotton, hemp, silk, hair, chemical fiber, etc. Some of the anti-ultraviolet fabrics compiled by better process have good absorption, conversion, reflection, and scattered ultraviolet rays in the 180-400Nm band.The fabric is non -toxic, no irritation to the Skin, and the human body does not have an allergic reaction, and does not affect the color of the fabric and the performance of hygroscopic vapor.Good anti-ultraviolet fabrics have a good absorption effect on ultraviolet rays of 100-400cm bands, especially UV-A and UV-B. After washing 50 times, the UV transposition is still lower than 1 %.The highest level.
