Abstract
A method for fiber modification provided in the present disclosure comprises the following steps: reacting fibers with a hypochlorous acid oxidant for development of antioxidant fibers, separating the antioxidant fibers from the hypochlorous acid oxidant and drying the antioxidant fibers to develop modified fibers which feature better oxidation resistance.
Claims8
A method of fiber modification for better storage stabilities of hypochlorous acids, comprising steps as follows:
- i. fibers react with a hypochlorous acid oxidant for development of antioxidant fibers, wherein temperature of reaction between the fibers and the hypochlorous acid oxidant ranges from 50 to 100° C., wherein duration of the reaction between the fibers and the hypochlorous acid oxidant ranges from 2 to 336 hours;
- ii. separating the antioxidant fibers from the hypochlorous acid oxidant;
- and
- iii. drying the antioxidant fibers for development of modified fibers.
