摘要：
PROBLEM TO BE SOLVED: To provide a method for producing a menstrual blood-impermeable non-woven fabric, which is capable of achieving a hydrostatic pressure of 350 mmH2O or more and an air permeability of 5000 cm3/m2·d·atm or more. SOLUTION: The method for producing a menstrual blood-impermeable nonwoven fabric, which comprises steps (1) to (4). (1) Preparation of menstrual blood impermeable finishing agent: After heating deionized water to a set temperature, stop the heating pump and put it in deionized water containing the menstrual blood impermeable finishing agent and penetrant measured in advance. Add and stir； (2) Immerse the SMS non-woven fabric in a menstrual blood impermeable finishing agent and perform a double-nip double dip； (3) Pre-bond the SMS non-woven fabric in an environment of 120 to 140° C. The adhesive coating layer of the SMS non-woven fabric after adhesion is cured in an environment exceeding 100° C.； (4) The tension of the SMS non-woven fabric is controlled by an automatic tension controller so that the M layer of the SMS non-woven fabric is not broken. [Selection diagram] None【課題】静水圧を３５０ｍｍＨ２Ｏ以上に達させることができる以外に、通気度を５０００ｃｍ３／ｍ２・ｄ・ａｔｍ以上にさせることができる経血不透過性不織布製造方法の提供。【解決手段】（１）～（４）のステップからなる経血不透過性不織布の製造方法。（１）経血不透過性仕上げ剤の調合：脱イオン水を設定温度まで加熱した後、加熱ポンプを止め、事前に計量した経血不透過性仕上げ剤と浸透剤を含む脱イオン水内に添加して撹拌し；（２）ＳＭＳ不織布を経血不透過性仕上げ剤に浸漬してダブルニップダブルディップを実施し；（３）１２０～１４０℃の環境内でＳＭＳ不織布を予め接着し、予め接着した後のＳＭＳ不織布の接着剤塗布層を１００℃を超えた環境内で硬化させ；（４）ＳＭＳ不織布のＭ層が破壊されないように、自動張力コントローラでＳＭＳ不織布の張力を制御する。【選択図】なし
