改善がはかられている。2. Description of the Related Art Surgical garments are mainly intended to prevent operators from being contaminated with bacteria. Traditionally, woven fabrics such as cotton and synthetic fibers have been used as materials for surgical gowns.
Since it is washed and reused, there is a problem that it may fray or break, the texture may be deformed or the water repellency may decrease as the number of times of washing increases, and blood such as bacteria may adhere. Dirty woven surgical clothes can be carried around in the hospital or carried out of the hospital to be washed and regenerated, and bacterial infection due to bacteria contained in blood etc. can occur inside and outside the hospital. There was also. Therefore, surgical gowns made from such woven fabrics are not desirable in terms of preventing bacterial infection. Therefore, non-woven fabrics have come to be used in terms of safety and hygiene and quality control. During surgery, a relatively large amount of blood or washing liquid often adheres to the surgical gown for a long time, so these liquids permeate to the back of the surgical gown with a non-woven fabric. Even if the amount is relatively small, there is a risk that it easily penetrates to the surface when pressed against an operating table or the like. Therefore, the non-woven surgical garment is treated with a water repellent treatment so that it does not penetrate into the inner layer even if blood containing bacteria adheres to it. ing.

Unlike ordinary non-woven fabrics, it does not adhere to the surface and slips well. Moreover, since the composite non-woven surgical garment of the present invention has good breathability even when sweating, it is possible to obtain an excellent effect that surgery can be performed comfortably.
