Modal fabric was pretreated with sodium hydroxide, sodium persulfate, and their combined mixture by pad-steaming procedure. The tearing strength of the pretreated modal fabric was measured for subsequent microfibrillation. The solubility of modal fiber in sodium hydroxide solution was highest at 10 % concentration of sodium hydroxide. Extended steaming of the modal fabric padded with 6% sodium hydroxide solution did not reduce the tearing strength appreciably. 2% sodium persulfate pretreatment greatly reduced the tearing strength of modal fabric within 7 minutes of steaming time. The pretreatment with combined composition of sodium hydroxide and sodium persulfate brought about stable reduction in tearing strength within 1 minute of steaming time, which would be appricable to the continuous pretreatment of modal fabric for microfibrillation. Microfibrillation behavior of the pretreated modal fabric was tested also. |
