に積層したもの等が用いられている。Conventionally, as a sheet material for surgery, a sheet-like material made of fiber provided with good water repellency, good antistatic properties and the like has been used. Also, when wearing gowns, etc., when water or blood is spilled during surgery, water and blood do not scatter around, but are absorbed on the gown surface and water or blood that has permeated the gown is exposed to the skin of the wearer. In some cases, water absorption and water resistance are required in order to prevent adhesion to water. Such things include, for example, the front of the gown and drapes,
Sheet materials made of fibers having good water absorbency, impermeable film materials, and sheets made of fibers having good antistatic properties are sequentially laminated.

となどが、問題となつていた。However, in the case of a sheet made of normal fibers (fiber diameter of 10 to 100 μm) imparted with good water repellency and antistatic properties, the fiber diameter is large and the gap between fibers is large, so that the water pressure resistance is small, If water or blood adheres to the sheet during long-term surgery, water or blood cannot be completely shut off and permeation occurs in the sheet. Therefore, when the above-mentioned sheet-like material is used for a gown or the like, there has been a problem that blood or the like adheres to the skin of the gown wearer and bacterial infection is likely to occur.

水性があり、通気性のあるものの開発が望まれていた。Further, among the conventional products, a sheet-like material made of fibers having good water absorption, a film-like material impermeable to water and the like, and a sheet-like material made of fibers having good antistatic properties are sequentially laminated to form an intermediate layer. Since non-breathable materials are usually used as the film-like material, when wearing a drape or the like using the same, there is a problem that unevenness occurs and the wearing comfort is extremely poor, and the gown comes off. Therefore, there is also a problem that only the front part can be used, and it takes time and effort to sew, and the development of a material having water absorbency, water resistance and air permeability has been desired.

に用いると、むれ等が発生し問題となる。The sheet-like material composed of the ultrafine hydrophobic fibers of the second layer according to the present invention has an average fiber diameter of 0.1 to 5.0 μm and a porosity of 50 to 50 μm.
80%. When the average fiber diameter exceeds 5.0 μm and the porosity is 50% or more, since the fibers are thick, if the porosity is the same as that of the thin fibers, the space between the fibers becomes large, so that the object of the present invention can be achieved. Does not have sufficient water pressure resistance. Therefore, the water resistance is required to be 200 mmH 2 O or more according to the JIS L 1092 5.1.1 A method. Also, the average fiber diameter exceeds 5.0 μm and the porosity is 50
%, The voids between the fibers are small, but the air permeability is insufficient. (To achieve the object of the present invention, JIS L 1096 6.27.
20 c.c./cm 2 / sec or more is required by the 1 A method. ) When used for gowns and the like, unevenness and the like occur, which is a problem.

Examples of the method for producing the nonwoven fabric include a melt blowing method and a flash spinning method. In particular, a sheet made of ultra-fine polypropylene fiber has a high water pressure resistance and is suitably used in the present invention. However, when the water pressure is insufficient, a water repellent is added to achieve the object of the present invention. Enough water pressure can be given. Examples of the water repellent include fluorine-based processing agents and the like, and the adhesion rate is suitably from 0.01 to 1.0% by weight.

することができる。Since the second layer uses ultra-fine fibers and has many fine fluffs, it is preferable to use the third layer as a surgical sheet often worn directly on bare skin. These materials and the method of forming a sheet are not particularly limited. Non-woven fabrics made of hydrophilic fibers such as cotton kipura and rayon, or hydrophobic fibers such as polyolefin fibers, polyamide fibers, and polyester fibers are used. The basis weight of the sheet-like material composed of these fibers is suitably 40 g / m 2 or less. If it exceeds 40 g / m 2 , the sheet is thick, hard, and has poor drape properties, and when used in a gown, it has a poor wearing feeling. By arranging a sheet made of ultrafine hydrophobic fibers on both sides of the sheet made of ultrafine hydrophobic fibers, the handleability of the superfine hydrophobic fiber sheet is improved, and various fibers are provided.

に、血液を介する細菌感染を防止する効果もある。The present invention is characterized in that, among the surgical sheet materials, the sheet-like material made of the fibers of the first layer has water absorbency, and the degree of water absorbency is 5 seconds according to JIS L 1096 6.26.1 A method. The following are appropriate: This measuring method measures the time for one drop of water to permeate. However, if it exceeds 5 seconds, the ability to quickly absorb water or blood, which is the object of the present invention, is insufficient, which is not preferable. As a method for imparting water absorption, hydrophilic fibers can be used as they are, and hydrophobic fibers can be used as appropriate surfactants such as fatty acid ether-based processing agents and phosphate ester-based processing. An agent or the like can be used after being attached at an adhesion rate of about 0.05 to 5.0%. For example, when the sheet material of the present invention is used for a gown, if the first layer is used as the outer side, even if water or blood is applied during the operation, the water or blood is prevented from scattering into the operating room or the like. Can be absorbed immediately by the outer layer of the gown. Also, since the second layer of the surgical sheet material of the present invention uses a sheet made of ultrafine hydrophobic fibers, water or blood absorbed by the outer layer does not penetrate further inside. , No wear on the skin of the wearer and a comfortable gown. Further, since the blood of the patient does not touch the skin of the wearer, there is also an effect of preventing bacterial infection via the blood.

ければ、耐水性の低下は起こらず、長時間にわたり良好
な性能を保持することが可能である。In the case where hydrophobic fibers are used for the first layer and water absorbency is imparted by a surfactant, it is preferable that the surfactant is not transferred to the second layer. To do so, change the material of the first and second layers and use a surfactant that is effective only for the first layer, or use an interface that does not flow down from the fiber together with water when water stagnates. It is necessary to use an activator. If the surfactant does not transfer to the second layer, the water resistance does not decrease and good performance can be maintained for a long time.

For example, a method using a hot melt adhesive, a method of partially fusing with a heated embossing roll, and the like are used. However, when joining the fibers by entanglement, the first
If the water-absorbing fibers of the layer are entangled with the second layer or the third layer, the water resistance of the second layer is reduced, which is not preferable.

When the fibers of the layer are hydrophobic fibers, it is desirable to impart good antistatic properties. 20 ° C 4
In an atmosphere of 0% RH, the voltage is preferably 1000 V or less according to the method shown in JIS L 1094 C method (a friction cloth is a cotton cloth). As a method for imparting antistatic properties, an appropriate antistatic imparting processing agent such as a fatty acid ester-based processing agent or a quaternary ammonium salt-based processing agent may be used. In the present invention, the second layer having a three-layer structure has water resistance as compared with the case where the sheet-like material made of one fiber is provided with water repellency and antistatic properties, which are contradictory performances, as in the related art. For this reason, the third layer only needs to provide the antistatic property alone, so that it is possible to provide a higher level of antistatic property than before.
