Description

  The present invention relates to a hygroscopic sheet for protective clothing, and more particularly to a hygroscopic sheet for protective clothing for removing moisture and odor of protective clothing such as radiation protective clothing and bulletproof vest for protecting a human body from radiation such as X-rays.

  In recent years, the number of endovascular treatments under fluoroscopy has been increasing with the expansion of minimally invasive treatments. In those procedures, a radiation protective garment made of a radiation shielding material is indispensable for protection against exposure.

  Radiation protective clothing is made of heavy metals such as lead, barium and antimony, and is heavy and has no breathability, so if you wear it for a long time, you will sweat a lot inside the protective clothing. After the operation, the protective clothing with sweat adhered is often put on a hanger and stored, which causes odors and molds and is a cause for medical personnel.

  Normally, radiation protection clothing is a sewn product and cannot be washed with water because water and detergent from the seams may deteriorate the inner shielding material. Therefore, alcohol cleaning is recommended for cleaning, but in reality, it is often only sprinkled with a commercially available deodorant antibacterial spray or the like.

  Therefore, in order to eliminate the harmful effects that occur when wearing radiation protection clothing, wear it in combination with radiation protection clothing to prevent the sticky feeling and offensive odor caused by the adherence of sweat even when the radiation protection clothing is worn for a long time. An underwear for radiation protection clothing and a wear body for radiation protection that can alleviate the discomfort of the wearer have been proposed (Patent Document 1).

  However, since the underwear for radiation protective clothing described in Patent Document 1 is worn under the radiation protective clothing, it has problems that it is bulky and has poor workability during surgery.
