Abstract

PURPOSE:To improve wearing feel by laminating a sheet which has a low- frictional layer on one surface of a lead-contg. org. high-polymer layer and a hardly contaminatable layer on the other surface and a sheet which has the low-frictional layer on one surface of a lead-contg. org. high-polymer layer and a good-to-touch layer on the other surface. CONSTITUTION:The 1st sheet S1 is constituted by providing the low-frictional layer 2 on one surface of the lead-contg. org. high-polymer layer 1 and the hardly contaminatable layer 3 on the other surface and the 2nd sheet S2 is constituted by providing the low-frictional layer 5 on one surface of the lead- contg. org. high-polymer layer 4 and the good-to-touch layer 6 on the other surface, respectively. The sheets S1, S2 are so laminated that the two low- frictional layers 2, 5 come into contact with each other. The laminate is so formed that the good-to-touch layer 6 of the 2nd sheet S2 is positioned on the inner side, i.e., wearer's side and the hardly contaminatable layer 3 of the 1st sheet S1 is positioned on the outer side. The radiation protective clothing which is highly flexible, is comfortable to wear and is hardly resistant to contamination even if the lead-contg. org. high-polymer layers of a high weight are included taherein is obtd. in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to radiation protection clothing particularly suitable as medical protective clothing, aprons, and the like.

[Conventional technology and its problems]

Conventionally, radiation protection clothing such as medical XL protective clothing and aprons are usually made of a material made of a barge organic polymer sheet with cloth surface materials adhered to both sides. Due to the low flexibility of the organic polymer sheet, conventional radiation protection clothing is generally uncomfortable to wear, and doctors who wear it feel psychologically fatigued after wearing it for a short period of time. The inherent high weight of molecular sheets added to the problem. With the rapid and advanced development of various medical technologies in recent years, medical technologies that utilize radiation are no exception, and for this reason, radiation protection clothing is even more comfortable to wear and causes less fatigue even when worn for long periods of time. Comfort has come to be demanded.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention is to solve the above-mentioned difficulties of the conventional materials for chi-ray protective clothing of this type.
More specifically, the objective is to develop radiation protection clothing that is comfortable to wear and causes less fatigue even when worn for long periods of time.

c) Means for Solving Problem] This problem consists of a first sheet having a low friction layer on one side of the lead-containing organic polymer layer and a stain-resistant layer on the other side, and a lead-containing organic polymer layer. A second sheet having a low-friction layer on one side and a skin-friendly layer on the other side is laminated such that both low-friction layers are in contact with each other, and the skin-friendly layer of the second sheet is placed on the inside. This problem is solved by radiation protection clothing characterized by being made of a composite material with the first sheet, the stain-resistant layer, on the outside.

[Function and structure of the invention]

In the present invention, since two sheets having lead-containing organic polymer layers are used, the thickness of the lead-containing organic polymer layer in each sheet is smaller than that of the lead-containing organic polymer layer in the conventional IN structure. Only half of the molecular layer is required, which increases overall flexibility because each sheet itself has excellent flexibility and the low-friction layers of the two sheets are in contact with each other. Extremely flexible. Moreover, since the side that comes into contact with the human body is a layer that is comfortable to the touch, it feels good to the touch, and combined with the above-mentioned flexibility, it is comfortable to wear and there is little fatigue even when worn for a long time.

Radiation protection clothing is generally susceptible to contamination on the outside with various drugs, human blood, etc., and clothing whose outside is contaminated causes discomfort to the wearer and others; however, the radiation protection of the present invention Clothing consists of a stain-resistant layer that does not easily stain the outer layer, or can be easily cleaned by lff even if contaminated. Therefore, the appearance of cleanliness also has the advantage of reducing psychological fatigue. Furthermore, since it is easy to clean by washing, etc., there is also the advantage that the cost required for storage and management is low.
