Descripción de la invenciónDescription of the invention

Los procesos de vulcanización del látex que incorpora una capa antiadherente como soporte del látex necesitan una cantidad de energía mayor que los procesos que utilizan un material textil como soporte, ya que en el proceso de vulcanización, la capa antiadherente impide en cierto grado la evaporación del agua por esa cara, y dificulta la transmisión de calor.The latex vulcanization processes that Incorporates a non-stick layer as latex support need an amount of energy greater than the processes that use a textile material as support, since in the process of vulcanization, the non-stick layer prevents the evaporation of water on that face, and hinders the transmission of hot.

En la presente invención se propone la fabricación de una lámina de látex espumado sobre un soporte textil, que posteriormente se retira. La baja adherencia entre el látex y el soporte textil facilita la retirada del mismo.In the present invention the manufacture of a foamed latex sheet on a support textile, which is subsequently removed. The low adhesion between Latex and textile support facilitates its removal.

En la etapa de vulcanización la lámina de látex que se soporta sobre una lámina textil tiene mejores características de permeabilidad y de transmisión de calor que las láminas de látex que se soportan sobre una lámina antiadherente.In the vulcanization stage the latex sheet which is supported on a textile sheet has better characteristics Permeability and heat transfer than latex sheets which are supported on a nonstick sheet.

De esta manera se consigue un látex espumado que elimina el agua de una forma óptima en el proceso de vulcanizado.In this way a foamed latex is achieved that eliminates water in an optimal way in the process of vulcanized

Al arrancar la lámina textil se deja a la vista una superficie irregular de celdillas abiertas que incrementa la transpiración de la lámina de látex.When you start the textile sheet it is visible an irregular surface of open cells that increases the perspiration of the latex sheet.

El soporte textil retirado puede reutilizarse una o más veces, reciclándolo, siendo este hecho beneficioso económicamente.The removed textile support can be reused one or more times, recycling it, this fact being beneficial economically.

Al eliminar la lámina textil, la lámina de látex final muestra las características originales del látex en cuanto a elasticidad y absorción de impactos, características que pueden variar si se mantiene la capa textil unida al látex.By removing the textile sheet, the latex sheet final shows the original characteristics of the latex in terms of elasticity and shock absorption, characteristics that can vary if the latex bonded textile layer is kept.

Un uso importante de las espumas de látex que no se muestran unidas a otros materiales, como es el caso del producto de la presente invención es el uso en colchones, tapicerías u otros sectores donde la amortiguación y el confort en general son importantes.An important use of latex foams that do not They are attached to other materials, such as the product of the present invention is the use in mattresses, upholsteries or other sectors where cushioning and comfort in general are important.
