A method for preparing functional cotton fabric by using divalent nickel ions to complex phytic acid

Abstract

The invention provides a method for preparing functional cotton fabric by divalent nickel ion complex phytic acid. The method comprises the following steps: (1) dissolving a divalent nickel ion salt into 50mL of water, adding cotton cloth, stirring at 60 DEG C for 30 minutes and taking out and drying the cotton cloth; (2) putting the processed cotton cloth into a phytic acid water solution and stirring the cotton cloth at 80 DEG C for 45 minutes; (3) cooling the cotton cloth to 0-5 DEG C and adding phenylamine; (4) slowly dropwise adding an ammonium persulfate water solution, and then standing for 30 minutes; and (5) taking out, washing and drying the processed cotton fabric. With divalent nickel ions as a phytic acid adsorbent, phytic acid is gathered on the surface of a cotton fiber; and the phenylamine is in situ polymerized on the surface of the cotton fiber on this basis, so that the cotton fabric has conductivity and flame retardant property. A flocculation technology of the divalent nickel ions on the phytic acid is combined with a phenylamine in-situ chemical synthesis technology, so that the washability of the phytic acid is improved; and the conductivity, the flame retardant stability and the durability of the cotton fabric are improved.

Description

Technical field [0001] The invention relates to a method for preparing functional cotton fabrics, in particular to a method for preparing functional cotton fabrics by complexing phytic acid with divalent nickel ions. Background technique [0002] With the advancement of science and technology, more electrical products have entered people's lives, bringing electromagnetic pollution to people, which is called the fourth largest pollution after air pollution, water pollution and noise pollution. After the human body is irradiated by excessive electromagnetic waves, blood, lymph fluid and cell protoplasm will change, causing DNA damage in cells and genetic mutations and deformities, which in turn induce leukemia and tumors, and also cause placental chromosomal changes. Lead to deformity of the baby or spontaneous abortion of pregnant women. [0003] Conductive polymers are organic polymers with adjustable conductive properties, especially polyaniline has been widely used in the fields...
