PURPOSE: To provide a nonwoven fabric composed of a nonwoven fabric of a specific hydrophobic filament and a specific short fiber web containing a hydrophilic fiber, satisfying air-permeability, water-resistance and wearing comfortableness at the same time and suitable for medical use.
CONSTITUTION: A filament nonwoven fabric having a number of hot-pressed recesses each having an area of 0.3-0.6mm2 and a short fiber web containing 40-70wt.% of a hydrophilic fiber (preferably regenerated fiber, etc.) are interlocked and integrated to a surface of a cloth of a hydrophobic filament such as polyolefin or polyester. The laminate is subjected to a fluid-jet treatment from the side of the short fiber web under a water-pressure of ≥80kg/cm2 and then to the fluid-jet treatment from the side of the nonwoven filament fabric to obtain a nonwoven fabric having an areal density of the nonwoven layer of 60-80g/m2 and a thickness of 0.3-0.6mm. This nonwoven fabric gives a nonwoven fabric material for medical use having a water- content of ≥5%, an air-permeability of 100-180cm3/cm2/sec, a water-resistant pressure of ≥12cm, a surface abrasion strength of ≥14, a tensile strength of ≥9.0kg/5cm width in longitudinal direction, a tearing strength of ≥0.8kg in longitudinal direction and a tensile strength of ≥2.5kg/5cm width in lateral direction and exhibiting excellent abrasion resistance and sanitariness.
