PURPOSE:To provide the subject flexible web not damaged with chlorine, containing no formaldehyde and having a reduced shrinkage factor on repeated washing treatments by adhering a phosphoamide compound to the cellulosic web, subjecting the web to a thermal treatment and subsequently treating the web with an aqueous acid solution. CONSTITUTION:A cellulosic web is immersed in an aqueous solution containing a phosphoamide compound to adhere 2 to 7wt.% of the active ingredient to the web, drying the web, treating the web with heat and subsequently treating the web with an aqueous acid solution containing othophosphoric acid or pyrophosphoric acid to provide a cellulosic web slightly damaged with chlorine. The phosphoamide compound includes cyclic amidephosphazenes and linear amidephosphazenes. The web is useful for clothing directly contacting with skins because the web does not contain formalin and does not give any chlorine injury to skins. |
