程において伸ばされすぎて不具合が発生するからである
。(Hereinafter, blank spaces) = 7 Table This wound dressing material (], OO) is designed to have an elongation rate of 20 to 100% in both the vertical and horizontal directions, and an elongation recovery rate of 60% or more in both the vertical and horizontal directions. , the reason is explained below. First, if the elongation rate is less than 20%, the elongation rate is too low and the wound dressing material (100) attached to the wound surface is difficult to expand in response to the movement of the wound surface and cannot move smoothly. Particularly when applied to an elbow, knee, etc., the movement is large and frequent, and the wound dressing (100) cannot follow the movement and peels off from the wound surface. In addition, if the elongation rate is 100% or more, the elongation rate is too high and it is difficult to adjust the draft in the manufacturing process of the wound dressing (100). This is because if it is stretched too much, problems will occur.
次に創傷被覆材（１００）の伸長回復率が６０％以下で

てそれが弛んでしわに成るためそのしわの部分が創傷面
と接触できす、従って創偏波覆材（１００）の機能が十
分発揮できなくなるからである。Next, when the elongation recovery rate of the wound dressing (100) is less than 60%, the recovery rate is too low, and even if it stretches to follow the movement of the wound surface, there are many parts that do not recover and remain elongated. , and since it loosens and becomes wrinkled, the wrinkled portion cannot come into contact with the wound surface, and therefore the function of the wound polarization dressing (100) cannot be fully exerted.
尚、本発明に係る創傷被覆材（１００）を製造する場合
について以下に詳述する。つまり第６図に示す如く、前
記抗菌剤を含有する前記熱可塑性樹脂の貯留槽（４０）
の中に編地の送出機（３０）より給送した編地を通過さ
せてこの編地に同樹脂を含浸する。In addition, the case of manufacturing the wound dressing material (100) according to the present invention will be described in detail below. That is, as shown in FIG. 6, there is a storage tank (40) for the thermoplastic resin containing the antibacterial agent.
The knitted fabric fed from the knitted fabric feeder (30) is passed through the knitted fabric to impregnate the knitted fabric with the resin.
次いで、これを図には表れない公知のマングルで絞って
同樹脂の付着量及び水分量を調整する。次いでこれを加
熱による第１乾燥機（５０）にて乾燥すると共に熱処理
をして同樹脂を編地に塗着させる。Next, this is squeezed with a known mangle (not shown in the figure) to adjust the amount of the resin attached and the amount of water. Next, this is dried in a first heating dryer (50) and heat treated to coat the resin on the knitted fabric.
そして、不織布の送出機（６０）より給送した同不織布

による第２乾燥機（９０）に給送して乾燥する。Then, an adhesive is applied to one side of the nonwoven fabric fed from the nonwoven fabric feeder (60) using an adhesive applicator (70),
This is fed to a bonding machine (80). Next, this is laminated with the knitted fabric that has passed through the first dryer (50), and then fed to the second dryer (90) which uses heating to dry it.
また前記熱可塑性樹脂に、編地と不織布とを仮接着でき

化できる。Further, if the thermoplastic resin is mixed with an adhesive sufficient to temporarily bond the knitted fabric and the nonwoven fabric, the adhesive applicator (70) and the first dryer (50) are unnecessary. As shown in FIG. 7, the process can be simplified compared to that shown in FIG.

As shown in FIG. 5, the product 0) moved smoothly even when applied to the elbow and moved frequently, and did not peel off from the wound surface. In addition, when this wound dressing material (100) was applied to the wound surface and removed after 1 day, 3 days, and 5 days, it was peeled off cleanly from the wound surface in each case, as shown in FIG. No adhesion to the same wound dressing material was confirmed. Furthermore, no symptoms such as suppuration were observed on the wound surface.
