Abstract

The invention relates to a method for plasticizing one or both surfaces of a nonwoven with polyethylene or polypropylene melted at a temperature of 400° C and stuck by cooling at a temperature of -4° C by means of contact with the pressure cylinders (Fig. 1) at a low temperature (-4° C). The displacement speed of the fabric is 15 m/min and the force of impregnation is 210 kg. force/cm2. The resulting nonwoven, whose fiber composition consists of polyester-rayon mixtures (ideally 50 %- 50 %), is a light fabric which is resistant to traction and tearing forces and totally impervious to water, blood, vapor and air and has a surface that absorbs liquids and moderately viscous substances, thereby making it suitable for the manufacture of disposable garments. The garments, which can be previously sterilized, can be bibs for children or adults undergoing dental treatment, bed sheets that are used during childbirth or surgery and gowns, trousers, shirts, camisoles, skirts and garments for medical staff. Aprons for housewives can also be manufactured.

5 Bi cuanto al espesor de la tela no tejida, éste se maneja en valores recomendables desde 0.20mrrt hasta O.δOmm., dando con esto un peso por metro cuadrado, según αl\Bv1X-CC-A72-1999-INNTEXM de 54 grs. hasta 66 grs. 5 Bi as for the thickness of the non-woven fabric, it is handled in recommended values from 0.20mrrt to O.δOmm., Giving with this a weight per square meter, according to α l \ Bv1X-CC-A72-1999-INNTEX M of 54 grs. up to 66 grs.
Paso seguido, se irtda el proceso plastificado de la tela no tejida con pdietileno ó i o pdípropileno y adherido por enfriamiento como a continuadón se anota.Afterwards, the plasticized process of the nonwoven fabric with pdyethylene or i or pdipropylene is adhered and adhered by cooling as follows.
En la fig. 1 se tiene el rdlo de la tela no tejida (1) cdocada en el soporte ó "caballete1' (2), el rdlo tiene un giro provocado desde el plegador (8) con el fin de desplazar la tela sobre la mesa (3) y por debajo de la cuba eléctrica (5) queIn fig. 1 you have the nonwoven fabric rim (1) placed in the support or "easel 1 '(2), the rdlo has a rotation caused from the folder (8) in order to move the fabric on the table (3 ) and below the electric tank (5) that
15 contiene el pdietileno ó pdipropileno, derretido, debiendo mantenerlo a 400°C, y el cual derrama dicha substanda sobre la tela que va corriendo a una veloddad de 15 metros por minuto aproximadamente. En seguida, la tela es sometida a la presión de una pareja de rodillos con superfides recubiertas de goma (6) con el fin de de garantizar la impregnadón del pdietileno ó pdipropileno, derretido sobre la parte15 contains the melted pdietileno or pdipropileno, having to keep it at 400 ° C, and which spills said substance on the fabric that is running at a speed of approximately 15 meters per minute. Next, the fabric is subjected to the pressure of a pair of rollers with rubber-coated surfaces (6) in order to guarantee the impregnation of the pdyethylene or pdipropylene, melted on the part
20 superior de la tela; ésta presión normalmerte es de 210 kg.fza/cm2. Así mismo, se asegura con dicha presión de impregnadón, un exprimido de la tela que evita la acumuiadón innecesaria de pdietileno ó pdipropileno, según el caso.20 upper fabric; This normal pressure is 210 kg.fza / cm2. Likewise, with said impregnation pressure, a squeezing of the fabric is avoided, which avoids the unnecessary accumulation of pdyethylene or pdipropylene, as the case may be.
HOJA SUSTITUTORIA REGLA 26 De inmediato, la tela entra en contado con una pareja de dlindros metálicos huecos (7), en los que las superficies se encuentran a una temperatura helada, menor a los 4°C bajo cero, y cuyo cambio drástico de temperatira, desde los 400°C a -4°C, provoca la plastificadón y adherenda del pdietileno ó pdipropileno sobre la tela no tejida.SUBSTITUTE SHEET RULE 26 Immediately, the fabric comes in with a pair of hollow metal cylinders (7), in which the surfaces are at an icy temperature, less than 4 ° C below zero, and whose drastic change in temperature, from 400 ° C to -4 ° C, causes the plasticization and adhesion of the pdietileno or pdipropileno on the nonwoven fabric.
Posteriormente y para finalizar el tratamiento de la tela no tejida, ésta es enrdlada por un plegador (8), que va acumulando la tela yá plastificada.Subsequently and to finish the treatment of the non-woven fabric, this is enriched by a folder (8), which accumulates the fabric and plasticized.
Es necesario hacer ndar, que el contrd de la veloddad de desplazamiento de la tela, debe mantenerse con andado, yá que un exceso provocaría una tensión elevada con el consiguiente riesgo de rasgar la tela, al mismo tiempo que no se derramaría la cantidad de pdietileno ó pdipropileno necesaria y conveniente a lo ancho y largo de ésta misma. Caso contrario, habría un exceso de materia plastificaπte sobre su superfide.It is necessary to make a swim, that the contrd of the speed of displacement of the fabric, must be maintained with walking, since an excess would cause a high tension with the consequent risk of tearing the fabric, at the same time that the amount of pdietileno would not spill or pdipropylene necessary and convenient throughout its width and length. Otherwise, there would be an excess of plastic material on its surface.
En caso necesario, una vez plastificada una superfide de la tela, ésta es llevada a una estampadora a cuadros o de rocfillos, con el fin de imprimir en la dra superficie las figuras necesarias, como pueden ser figuras infantiles destinadas a la ccπfecdón de baberos para niños, con la alternativa de que dicha impresión sea artes del plastificado.If necessary, once a surface of the fabric has been laminated, it is taken to a plaid or roll printer, in order to print on the surface the necessary figures, such as children's figures intended for the bibfection of bibs for children, with the alternative that this impression is plastic arts.
