A method for shaping fibrous material comprising: - applying to fibrous material a crosslinking composition comprising a photocatalyst and an active agent capable of crosslinking fibrous material wherein the photocatalyst is a hydroxyl-substituted aromatic compound; wherein the active agent is selected from the group consisting of: arabinose, citric acid and ethylene carbonate, and mixtures thereof; and then - shaping the fibrous material with an appliance comprising: - a first arm pivotable with respect to a second arm, the first arm and the second arm thereby configured to form a clamp for receiving fibrous material positioned between the first and second arms (2, 3) when the appliance is in a closed position; - wherein the first arm comprises a first inner face which faces the second arm; - and wherein the second arm comprises a second inner face which faces the first inner face on the first arm; - and wherein a first plate extends upon a portion of the first inner face; - and wherein a second plate extends upon a portion of the second inner face; - wherein both the first plate and the second plate are substantially flat; - wherein a heating element is provided in at least one of the first arm and/or the second arm; - wherein at least one light source is provided in at least one of the first arm and/or the second arm; - and wherein the first inner face and/or the second inner face respectively comprise a heat-transmitting area and/or a light-transmitting area; - and wherein the heating element is located proximal to the heat-transmitting area and wherein the light source is located proximal to the light-transmitting area; - and wherein when the appliance is in the closed position, the portion of the fibrous material received between the first inner face and the second inner face receive light energy from the light source and heat energy from the heating element. - applying to fibrous material a crosslinking composition comprising a photocatalyst and an active agent capable of crosslinking fibrous material wherein the photocatalyst is a hydroxyl-substituted aromatic compound; wherein the active agent is selected from the group consisting of: arabinose, citric acid and ethylene carbonate, and mixtures thereof; and then - shaping the fibrous material with an appliance comprising: - a first arm pivotable with respect to a second arm, the first arm and the second arm thereby configured to form a clamp for receiving fibrous material positioned between the first and second arms (2, 3) when the appliance is in a closed position; - wherein the first arm comprises a first inner face which faces the second arm; - and wherein the second arm comprises a second inner face which faces the first inner face on the first arm; - and wherein a first plate extends upon a portion of the first inner face; - and wherein a second plate extends upon a portion of the second inner face; - wherein both the first plate and the second plate are substantially flat; - wherein a heating element is provided in at least one of the first arm and/or the second arm; - wherein at least one light source is provided in at least one of the first arm and/or the second arm; - and wherein the first inner face and/or the second inner face respectively comprise a heat-transmitting area and/or a light-transmitting area; - and wherein the heating element is located proximal to the heat-transmitting area and wherein the light source is located proximal to the light-transmitting area; - and wherein when the appliance is in the closed position, the portion of the fibrous material received between the first inner face and the second inner face receive light energy from the light source and heat energy from the heating element.
