Process for sticking chemical to fibrous article

A process for impregnating steel wool with soap and forming the steel wool into a scouring pad, which comprises the steps of:

• placing a quantity of steel wool into the cavity of a mold, said mold having a vapor-pervious bottom wall, a vapor-pervious top wall and side walls, said top wall and said bottom wall being spaced apart so that said cavity is enlarged;
• extending injecting nozzle means into the central internal zone of said quantity of steel wool in said mold cavity and injecting through said nozzle means, into said quantity of steel wool, a stream of liquid aqueous soap composition containing from 50 to 70% by weight of soap, said composition being at a temperature of from 110.degree. to 200.degree. C. and under a pressure of from 1.5 to 20 Kg/cm.sup.2 effective to prevent vaporization of the water contained in said composition until said composition enters said quantity of steel wool from said nozzle means so that when said liquid aqueous soap composition enters said quantity of steel wool, the water therein flash evaporates into steam and the steam flows to and through said vapor-pervious bottom and top walls and thereby the soap is carried by the steam and is deposited on the steel wool to form a substantially uniform distribution of said soap adhering to said quantity of steel wool;
• then removing said nozzle means from said quantity of steel wool;
• and then relatively moving said top wall and said bottom wall toward each other to compression mold said quantity of steel wool to form a scouring pad.
