| description | A hydrophilic melt-extruded multicomponent polymeric strand including a first melt-extrudable polymeric component and a second melt-extrudable, hydrophilic polymeric component, the first and second components being arranged in substantially distinct zones across the cross-section of the multicomponent strand and extending continuously along the length of the multicomponent strand, the second component constituting at least a portion of the peripheral surface of the multicomponent strand continuously along the length of the multicomponent strand. The second component renders the strand hydrophilic and preferably has a critical surface tension at 20 DEG C greater than about 55 dyne/cc, and more preferably greater than about 65 dyne/cc. A suitable hydrophilic second component comprises a block copolymer of nylon 6 and polyethylene oxide diamine. Suitable polymers for the first component include linear polycondensates and crystalline polyolefins such as polypropylene. Nonwoven fabrics and absorbent articles made with the hydrophilic multicomponent polymeric strands are also disclosed. |
