Abstract
Methods for treating a fibrous substrate are provided via positioning a treatment sheet adjacent to the fibrous substrate and positioning a heat treatment device onto the treatment sheet. The treatment sheet comprises a base sheet saturated with a treatment composition. The heat treatment sheet comprises a board formed and a flexible pad attached to the board, with the flexible pad comprises a conformable surface. Then, the method includes: pressing the board of the heat treatment device with the hot press member such that the conformable surface of the flexible pad presses onto the treatment sheet to transfer the treatment composition from the treatment sheet to the fibrous substrate using a wetting solution to carry the salt from the treatment sheet into the fibrous substrate; removing the heat treatment device and the treatment sheet from the fibrous substrate; and drying the fibrous substrate with the hot press member.
