The chemical structure of aminopropyl cellulose is represented as follows : cellulose-g-CH2CH2CH2-NHa. The degree of substitution may be varied with the immunization process to be employed in previous papers. The amino groups in it undergo various reactions which are characteristic of aliphatic primary amines, Therefore in this paper, dyeing properties of the aminopropyl cellulose for the anionic dye and the reactive dye were investigated. The adsorption capacity of metal ion by it was also measured and the application of it to the crease-resistant finish was discussed.
