摘要： PURPOSE:To obtain a melt blown nonwoven fabric having a homogeneous basis weight distribution in the width direction by increasing the width of arranged jetting gas ports installed adjacently to plural discharge holes for a molten polymer from that of the discharge hole row for the molten polymer by a specific value or above. CONSTITUTION:The width of jetting gas ports 10 and 10' is set at a value >=2cm, preferably >=10cm larger on one side than that of a row of discharge holes 11 for a molten polymer. thereby, gas streams jetted from the widely installed parts act as a barrier for accompanying air streams in melt blowing and the basis weight distribution of the nonwoven fabric at the ends in the sheet width direction is homogenized to reduce also the difference in size between the central part and the ends of the sheet.

摘要： PURPOSE: To obtain a sanitary sheet auxiliary material which is a nonwoven fabric prepared by interlacing specific hydrophilic ultrafine synthetic fibers, having dense layers in the front and the back surface parts and further a prescribed reentering index of water and excellent in water retaining power, water holding power and durability in washing. CONSTITUTION: This auxiliary material is a nonwoven fabric prepared by interlacing hydrophilic ultrafine synthetic fibers having g/cm reentering index of water. The hydrophilic ultrafine synthetic fibers are preferably composed by directly introducing hydrophilic functional groups (most preferably hydrohilized by plasma treatment) or a compound having the functional groups (most preferably an acidic group-containing polymer or a polymer having alkylene glycol units) into at least the surfaces of the fibers.
