Abstract

Описан способ регенерации целлюлозных волокон, имеющих небольшое повреждение, из использованного впитывающего изделия, которое содержит целлюлозные волокна и супервпитывающий полимер. Использованное впитывающее изделие обрабатывают при температуре, большей или равной 80°C, раствором органической кислоты, имеющим pH не выше 2,5, и супервпитывающий полимер инактивируется. Предпочтительно, если целлюлозные волокна и инактивированный супервпитывающий полимер отделяются от использованного впитывающего изделия после обработки водным раствором органической кислоты и затем смесь, включающую отделенные целлюлозные волокна и инактивированный супервпитывающий полимер, обрабатывают окислительным реагентом, инактивированный супервпитывающий полимер разлагается, уменьшается его молекулярная масса, и он солюбилизируется.
