    Abstract: A brush roller and its manufacturing method and brush roller mold is provided, the brush roller is manufactured by foaming a gaseous pore filler, while solving the problem of using a solid pore filler foaming method to manufacture the brush roller. In addition, the brush roller of the present invention has a plurality of fluid channels communicating between any adjacent two, and the plurality of fluid channels respectively extend to the surface of the brush roller to form pores to improve the fluid permeability of the brush roller, and in the brush roller manufacturing method of the present invention, after the PVA emulsified solution is cured, the compressive stress under the condition of the predetermined compression ratio can be formed to meet the expected brush roller, and it can be used to brush the circuit substrate.

    Abstract: The present invention describes a method for the production of a spinning dope composition, said method comprising a homogenization involving vigorous mixing of a cellulosic pulp material in alkali solution, vigorous mixing implying supplying a power density to agitators used in the homogenization step of at least 150 kW/m3 (kW supplied to agitators per mixed unit of liquid volume), and thereafter a dissolution involving mixing of the cellulosic pulp material in the alkali solution to obtain a spinning dope composition, wherein the power density supplied to agitators used in the dissolution step is maximum 75 kW/m3 (kW supplied to agitators per mixed unit of liquid volume); and wherein the cellulosic pulp material in alkali solution is kept at a temperature of less than 0° C. during the homogenization and during at least part of the dissolution. The present invention is also directed to a system intended for the production of a spinning dope composition.
