| Popis: | 91 The purpose of this study is to use whitening agents dye on whiten cellulose. In the meantime We controlled chitosan solution between PH3 and PH5 to coat on the fabric.We tested the fabric their whiteness、anti-microbial and to know the effect of the process、PH value. The results indicated that to process in once bathe couldn’t achieve high whiteness，cause to adopt twice process. While the chitosan’s concentration increase the anti-microbial properties would be increase，the fabric’whiteness would be decreased. Dissolve chitosan in low PH value would increase the electropositive of amide and the anti-microbial properties would increase. To wash the fabric after the anti-microbial properties would be reduce but the anti-microbial properties still to remain. |
