A method of producing a nonwoven textile structure comprises the steps of: (a) stretching a plurality of substantially parallel continuous tow filaments 1 of absorbent material, such as cellulose acetate or solvent spun rayon, to provide a filament assembly, (b) consolidating the resulting filament assembly 4 by a compacting operation (at 5) to produce a three-dimensional rod or pack while maintaining substantially uninterrupted capillarity along the entire length of the filament assembly, and (c) wrapping the three-dimensional rod or pack 6 in a water porous material 7. A plurality of the resulting wrapped rods or packs 9 may then be incorporated into a composite structure, such as that used for a thin diaper. Such wrapped rods or packs exhibit excellent fluid transmission and wet strength characteristics and may be used in the fields of sanitary protection, infant care and adult incontinence protection. |
