摘要： A plurality of substantially parallel continuous filaments, e.g. of cellulose acetate or rayon, and preferably newly formed, are consolidated or partially stabilised, e.g. by application of solvent and pressure, by hydroentanglement, by embossing, or by crimping and stretching. The filament assembly or subassemblies thus produced are further stabilised by folding, bundling, twisting or intertwining, e.g. to form braids (10), and are then bonded to a carrier layer or sandwiched between outer layers (12, 14), e.g. by hydroentanglement, melt blowing, spinbonding etc. The stabilised filament assemblies may be arranged spaced transversely and may be cut just prior to bonding so as also to provide longitudinally spaced three dimensionally thicker regions, ready for conversion to finished products such as absorbant feminine hygiene products or medical swabs or the like.

摘要： 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 capillary 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.

摘要： In order to produce a nonwoven fabric having elastomeric properties spun filaments (1), consisting preferably (but not essentially) of cellulose material such as cellulose acetate or solvent spun rayon, not in yarn formats, are corrugated or crimped in an overfeed process, as in stuffer box (6), into stabilized three dimensional batts. A proportion of filaments (3) of a thermal memory material, such as modified polyester, in a stretched format are included. The resulting batt is then subjected to controlled hydroentangling and a controlled heat treatment to yield three dimensional nonwoven fabrics with elastomeric properties due to contraction of the stretched filaments. Elastomeric memory material activated to shrink by ultrasonic treatment may be used in place of thermal memory material. The elastomeric properties can be adjusted to suit end-use requirements and applications are envisaged in the medical and hygiene areas.

摘要： A method of producing a nonwoven textile structure comprises the steps of: (a) stretching a plurality of substantially parallel continuous tow filaments (1), such as cellulose acetate or solvent spun rayon, to provide a partially stabilized filament bundle (5) and (b) folding or corrugating the stretched bundle in a stuffer box process (at 6) which includes air or steam injection (at 7) so as to increase its bulk and loft. The resulting material is consolidated so as to maintain substantially uninterrupted capillarity along the entire length of the resulting filament bundle. This may be accomplished by a controlled light hydroentanglement process (at 8) employing either widely spaced water injection manifolds or low water pressure. Alternatively it may be accomplished by light tacking using thermal spot calendaring or ultrasonic means. Either technique provides sufficient strength and integrity to the tow assemblies to facilitate handling during further processing, such as bonding to a carrier layer to provide a bandage or incorporation between outer layers, whether pre-cut or not, to provide smaller dressings or elongate bandages.
