patent abstract: "new method for staining and treating substrates". The present invention relates to a method for applying a treatment agent to a substrate, the method comprising treating the pre-wetted substrate in an aqueous system containing the particulate solid treatment agent in a closed container, the treatment being performed. with a liquor to substrate ratio not exceeding 2: 1. typically the method is applied to the dyeing of textile fibers with liquor ratios of = 1: 1 and is performed in the absence of conventionally included additives for the sole purpose of promoting dye absorption by controlling electrical interactions or otherwise enhancing interactions. between the substrate and the treatment agent. The invention also provides a method for removing excess treatment agents after applying said treatment agents to a substrate, said method comprising no more than three treatments of washing said substrate with water after said application. said washing process includes, more particularly, a two stage process comprising performing, in order, the steps of: a first washing of the water treated substrate in a closed container with a water to substrate ratio not exceeding 5: 1 ； and a second wash of the water treated substrate in a closed container with a water to substrate ratio not exceeding 10: 1.resumo patente de invenção: "novo método para coloração e tratamento de substratos". a presente invenção refere-se a um método para aplicação de um agente de tratamento a um substrato, o método compreendendo o tratamento do substrato pré-molhado em um sistema aquoso contendo o agente de tratamento sólido particulado em um recipiente fechado, o tratamento sendo realizado com uma relação do licor para substrato que não excede 2:1. tipicamente, o método é aplicado ao tingimento de fibras têxteis com relações de licor de =1:1 e é realizado na ausência de aditivos convencionalmente incluídos com o único propósito de promover absorção de corante pelo controle de interaçõ
