Sunscreen Shirt Is Cool And Sunscreen.

< p > > a href= "http://sjfzxm.com/news/index_f.asp" > sunscreen shirt < /a > is a popular term in the past two years. The main function of sunscreen is to control the direct ultraviolet radiation of the sun, which is the same as that of the sun umbrella, which makes the skin black from the sun. This is a compulsory course for many women.

The biggest feature of sunscreen is plucency, which is cool and sunscreen.

< p > reporter learned from Shi Shi fiber supervision and inspection department and quality supervision department that our country's latest "a target=" _blank "href=" http://www.91se91.com/ "> textile > /a > Product ultraviolet protection performance evaluation" stipulates that only when the UPF (i.e. the UV protection coefficient) is greater than 30, and the UVA (UVB) pmittance is less than 5%, it can be called "anti ultraviolet products". The anti ultraviolet products should be labeled on the label with the following three aspects: the number of this standard is gb/t18830, UPF value: 30+ or < < >.

The consumers are reminded that when choosing the anti ultraviolet textile and clothing products, we should first check whether the product manual has the function of UV protection. If there is anti ultraviolet function, we should also ask for the inspection report issued by the provincial and municipal quality supervision and inspection authority authorized by the State Administration of quality and technology supervision to confirm whether the product meets the national standard.

The main reference index of sunscreen products is the UPF index. We should try to select the products of UPF, that is, the ultraviolet protection coefficient (>30) and the T (UVA) (i.e., the ratio of the pmission flux to the incident flux) of <5% when the UV wavelength is between 315cm and 400cm.

In addition, the color of the clothes can also affect the sun protection performance. The yellow color has the lowest sunscreen performance, and the black and red protective clothing is relatively better.

< p > < strong > sun protection principle < /strong > < /p >

< p > sunscreen garments first became popular in the United States in 2007, and then entered China.

In China, the application of UV protection less than a target= "_blank" href= "http://www.91se91.com/" > cloth > /a "is mostly applied to outdoor products, and the application of ordinary clothing is still relatively small.

< /p >

< p > in fact, the production principle of sunscreen fabric is very simple. In fact, it is to add sunscreen AIDS into cloth, and to make cloth thicker after special needs.

The so-called thick finishing is to make cloth density more large.

< /p >

< p > January 1, 2011, China launched the latest assessment standard "textile UV protection performance evaluation".

It is stipulated that only when the UPF of the product is greater than 30 and the UVA pmittance is less than 5% can it be called "anti ultraviolet product"; the anti ultraviolet product should be labeled on the label with the following three aspects: 1. the number of the standard, that is, gb/t18830; 2.upf value: 30+ or 50+; 3., for long-term use and under tensile or humid condition, the protective performance of the product may be reduced.

< /p >

< p > in this evaluation standard: uva refers to the part of the band which is the most harmful to the human body in ultraviolet radiation, while UPF refers to the degree of pmission of ultraviolet light, the greater the value, the lower the degree of pmission.

< /p >

< p > because most of the sunscreen fabrics are based on the principle of adding auxiliaries, it may result in reduced sunscreen performance after repeated washing, but this does not violate the relevant regulations of the state.
