摘要:
A method for manufacturing a fibrous structure, the method comprising the steps of: combining a plurality of filaments and a plurality of solid additives in a collection device, wherein the collection device is a design or molded tape resulting in the structure fibrous that has a surface design; and calendering of the fibrous structure while the fibrous structure is still in the collection device, such that a fibrous structure is formed that contains less than 30% by weight of the fibrous structure of the filaments and that has a fraying result dry, as determined according to the Fray Test Method described herein, of less than 2.5; wherein the filaments are selected from the group consisting of natural polymers, such as starch, starch derivative, cellulose and cellulose derivatives, hemicellulose, hemicellulose derivatives, chitin, chitosone, polyisoprene (cis and trans), peptides, polyhydroxyalkanoates , and synthetic polymers that include thermoplastic polymer filaments comprising thermoplastic polymers, such as polyesters, nylon, polyolefins, polyvinyl alcohol and polyvinyl alcohol derivatives, sodium polyacrylate filaments, and copolymers of biodegradable or compostable thermoplastic polyolefins, such as filaments of polylactic acid, polyvinyl alcohol filaments and polycaprolactone filaments. and wherein the solid additives are selected in the group consisting of wood pulp fibers and synthetic staple fibers.Un método para fabricar una estructura fibrosa, comprendiendo el método las etapas de: combinar una pluralidad de filamentos y una pluralidad de aditivos sólidos en un dispositivo de recolección, en donde el dispositivo de recolección es una cinta de diseño o moldeada que resulta en la estructura fibrosa que presenta un diseño de superficie; y calandrado de la estructura fibrosa mientras que la estructura fibrosa está todavía en el dispositivo de recolección, de tal manera que se forma una estructura fibrosa que contiene menos del 30% en peso de la estructura
