Abstract
La presente invencion se refiere a un proceso para aplicar bajos niveles de un compuesto de polisiloxano funcional y un compuesto de polisiloxano no funcional o aceite mineral a una trama seca de papel higiénico, dicho proceso caracterizado porque comprende los pasos de: a) proporcionar una trama seca de papel higiénico; b) mezclar un compuesto de polisiloxano funcional con un compuesto de polisiloxano no funcional o aceite mineral adecuado, para formar una solucion que contiene un polisiloxano funcional; c) mezclas dicha solucion que contiene polisiloxano funcional con agua y un emulsificador de agente tensioactivo adecuado para formar una emulsion que contiene polisiloxano funcional; d) aplicar dicha emulsion que contiene polisiloxano funcional a una superficie caliente de transferencia; e) evaporar por lo menos una parte del agua de dicha superficie caliente de transferencia para formar una película que contiene dicho compuesto de polisiloxano funcional y dicho compuesto de polisiloxano no funcional o dicho aceite mineral; y f) transferir dicha película desde la superficie caliente de transferencia hacia cuando menos una superficie que mira hacia afuera de la trama de papel higiénico contactando dicha superficie de trama que mira hacia afuera con dicha superficie de transferencia caliente, con lo cual se transfiere una cantidad suficiente de dicho compuesto de polisiloxano funcional, tal que de aproximadamente 0.004% aproximadamente 0.75%, de preferencia de 0.01% a 0.3% de dicho compuesto de polisiloxano funcional basado en el peso en seco de la fibra de dicha trama de papel higiénico, se retiene por dicha trama de papel higiénico, y en donde la relacion en peso del compuesto de polisiloxano funcional al compuesto de polisiloxano no funcional o aceite mineral retenido por la trama de papel higiénico varía de 19:1 a 1:19, de preferencia de 1:9 a 3:1.
