    Fabric, Are You Wearing Sunscreen Clothes Really Sunscreen?

    2018/6/26 12:03:00 491

    FabricSunscreenUV.

    Sunscreen clothing has been popular in recent years in China, especially women.

    Can sunscreen really block ultraviolet rays? Many people will have doubts.

      

    Sunscreen standard for sunscreen clothing

    In fact, all clothes have sunscreen ability, but not all clothes can be called sunscreen clothing. In our national standard (GB/T18830-2009), the evaluation of ultraviolet radiation resistance of textiles, it is clearly stipulated that UPF is greater than 40, and the pmittance of UVA is less than 5%. At the same time, these two conditions can be satisfied before they can become "anti ultraviolet products".

    The UPF value is similar to the SPF value of sunscreen, representing the ability of textiles to protect against ultraviolet radiation. UPF calculation method: the average effect of ultraviolet radiation calculated on the skin without protection is proportional to the average effect of ultraviolet radiation calculated on the skin when fabric is protected.

    For example, a UPF40 sun protection clothing, on behalf of the

    Textile

    Under the protection, the UV intensity that can be passed is the original 1/40.

    There is no uniform standard for UV protection textiles in the world. The US and Australian standards are the same as those of UPF>15 and Europe and China.

    However, the two methods can not be simply compared. The UPF method and conditions are different, and the final UPF value is quite different.

      

    Sun protection principle of sunscreen clothing

    There are mainly two ways to protect sunscreen from sunscreen: one is physical sunscreen, the other is adjuvant sunscreen, each of which has its own characteristics in two ways.

    Physical sunscreen

    adopt

    Fabric

    The thickness and the density of the yarn to achieve the function of blocking ultraviolet rays are simple and crude.

    Disadvantages are thick and airtight, poor comfort.

    But now the material of sunscreen clothing is also improving. The polyester fiber material commonly used can be lightweight and breathable.

    Assistant sunscreen

    In order to make up for the shortage of physical sunscreen, some sunscreen clothes will add sunscreen auxiliaries, such as nano titanium dioxide, Zinc Oxide, salicylate, etc., to achieve the effect of sunscreen. There are three main ways:

    1. Coating method

    Apply a sunscreen agent to the inside of the sunscreen to achieve sunscreen effect.

    This method is the simplest and cheapest. The drawback is that it has poor air permeability. After washing, the coating is easy to fall, resulting in reduced sunscreen ability. Cheap sunscreen clothes are mostly used in this way.

    2. Pasting and baking method

    Soaking textiles in auxiliaries and drying them under certain conditions, so that the auxiliaries and textiles can be firmly bonded together, with medium cost and long time. The additives will fall off and prevent ultraviolet radiation from falling.

    3. Melt spinning

    The yarn that is directly added to the spinning solution is a yarn with UV protection capability.

    High cost, limited choice of sunscreen AIDS, the best UV protection effect, usually used in some professional, high-end sunscreen clothing.

    Do you need sunscreen cream for sunscreen?

    Now the sun protection clothing on the market is not so reliable, and can not be completely protected against ultraviolet radiation. If you want to put sunscreen on sunscreen clothes, I'm afraid you will be disappointed.

    Especially when exposed to the sun for a long time, sunscreen and sunscreen are the best sunscreen.

    If your daily work life is mainly indoors, just for a short time exposure to the sun, sunscreen and sunscreen can be chosen one by two.

    Even some sunscreen that can reach the standard can not achieve 100% protection against ultraviolet radiation. There will always be a net leak. If exposed to sunlight for a long time, tanning is a big probability event.

    In summary, sunscreen clothing is a good sunscreen option for UV protection, but it can not rely entirely on sunscreen. It is best to combine sunscreen and sunscreen, especially when exposed to sunlight for a long time.
