Abstract
Se describe una capa de transferencia y un proceso para su fabricación, para ser usada en artículos absorbentes desechables, tales como pañales desechables para bebés, pañales desechables para adultos incontinentes, calzones entrenadores o toallas femeninas, que mejora notablemente las características de la matriz absorbente de dichos artículos, sobre todo después de la primera descarga. La capa de transferencia de la presente invención es una tela no tejida que está formada por una mezcla de al menos dos tipos de fibras sintéticas unidas por calor, mezcladas y procesadas de tal manera que se obtienen las características deseadas en cuanto a distribución, tiempo de penetración e hidrofilicidad después de varias descargas de líquidos. El proceso para fabricar la capa de transferencia consiste en pre-mezclar dos o más tipos de fibras sintéticas tales como poliéster y polipropileno, o cualquier otro tipo de fibra sintética adecuada para este fin, alimentarlas a un abridor donde se abren las fibras y se mezclan homogéneamente; esta mezcla es alimentada a la o a las cardas respectivas, antes de entrar a las mismas se forman la o las capas de las que se obtienen velos de fibras, por último pasan por una calandra que une las fibras mediante calor. Cuando esta película es usada como capa de transferencia en artículos absorbentes desechables, se obtienen mejoras de alrededor de 30 a 50% en cuanto a permeabilidad al líquido y retorno del líquido a la superficie después de varias descargas.<EMI FILE="00076961_1" ID="1" IMF=JPEG >A transfer layer and a process for its manufacture are described, for use in disposable absorbent articles, such as disposable diapers for babies, disposable diapers for incontinent adults, training briefs or female towels, which significantly improves the characteristics of the absorbent matrix of these articles, especially after the first download. The transfer layer of the present invention is a non-woven fabric that is formed by a mixture of at least two types of heat-bonded synthetic fibers, mixed and processed in such a way that the desired characteristics are obtained in terms of distribution, timing of penetration and hydrophilicity after several discharges of liquids. The process for manufacturing the transfer layer consists of pre-mixing two or more types of synthetic fibers such as polyester and polypropylene, or any other type of synthetic fiber suitable for this purpose, feeding them to an opener where the fibers are opened and mixed. homogeneously; This mixture is fed to the respective card (s), before entering them, the layer or layers from which fiber veils are obtained, finally pass through a calender that joins the fibers by heat. When this film is used as a transfer layer in disposable absorbent articles, improvements of about 30 to 50% are obtained in terms of liquid permeability and return of the liquid to the surface after several discharges. <EMI FILE = "00076961_1" ID = "1" MFI = JPEG>
