METHOD FOR MANUFACTURING A DYE SCAVENGING SUBSTRATE |
摘要 |
A method for manufacturing a dye scavenging substrate which comprises the steps of: (a) providing an absorbent substrate; (b) passing the substrate through a bath containing an alkaline solution of a dye scavenging compound selected from: (i) a N-trisubstituted ammonium-2-hydroxy-3-halopropyl compound having the general formula (I), or (ii) a salt of epoxy propyl ammonium having the general formula (II), or a combination thereof; (c) subjecting the substrate to a pressure of from about 0.04 MPa to about 0.40 MPa; (d) wrapping the substrate in a water impermeable material and rotating the substrate for a period of from about 12 hours to about 60 hours; (e) removing the water impermeable material and passing the substrate through a bath containing an acid solution; (f) subjecting the substrate to a pressure of from about 0.15 MPa to about 0.40 MPa; and (g) drying the substrate. |
