Patent

CA 2402204

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.

La présente invention concerne une pluralité de filaments continus sensiblement parallèles, d'acétocellulose ou de rayonne par exemple, de préférence nouvellement formés, qui sont consolidés ou partiellement stabilisés, par exemple par application d'un solvant et d'une pression, par liage par jet d'eau, par frappage ou par crêpage et étirage. On complète la stabilisation de l'ensemble ou des sous-ensembles de filaments ainsi obtenus par pliage, formation de faisceaux, câblage ou entrelacement afin de former des tresses (10), et ils sont ensuite liés à une couche de support ou intercalés entre des couches extérieures (12,14), par exemple par liage par jet d'eau, fusion-soufflage, filage-liage, entre autres. Les ensembles de filaments stabilisés peuvent être séparés et agencés transversalement les uns par rapport aux autres, et ils peuvent être coupés juste avant le liage de manière que l'on obtient trois régions aux dimensions plus épaisses séparées longitudinalement, prêtes à être transformées en produits finis tels que serviettes hygiéniques, tampons médicaux ou analogues.
