(57) [Abstract] [Purpose] The coloring is a different color pattern, and the color fastness and fastness are high. Excellent tensile strength, moisture permeability, waterproofness, windproofness, etc., and A composite non-woven fabric having a filter property, a blood barrier property, an oil adsorption property, a chemical resistance, etc. is obtained. [Structure] Average fiber diameter 5 microns or less, basis weight 10-200 A melt-blown nonwoven fabric (A) composed of g / m 2 is laminated on at least one surface thereof with a spunbonded nonwoven fabric (B) composed of a colored fiber having an average fiber diameter of 10 microns or more and a basis weight of 10 to 80 g / m 2 , and Are partially integrated by heat bonding to form a composite non-woven fabric. |
