Abstract
The invention provides a method for preparing a functional cotton fabric by layer-by-layer assembly of phytic acid via cationic polyacrylamide. The method comprises the following steps: (1) dissolving cationic polyacrylamide in 50 mL of water, adding cotton cloth, soaking for 30 min at the room temperature, taking out and drying; (2) placing the treated cotton cloth in a phytic acid water solution, soaking for 30 min at the room temperature, taking out and drying; (3) repeating the steps (1) and (2) for several times; (4) cooling to be 0-5 DEG C, and adding aniline; (5) slowly dripping an ammonium persulfate water solution, and after that, leaving to stand for 30 min; (6) taking out the treated cotton fabric, washing and drying. According to the method, cationic polyacrylamide serves as a phytic acid adsorbent, phytic acid is enriched on the surface of the cotton fiber via layer-by-layer assembly, and on the basis, aniline is polymerized on the surface of the cotton fiber in situ, so that the cotton fabric is endowed with electric conductivity and flame retardant property; the cationic polyacrylamide and phytic acid layer-by-layer assembly technology and the polyaniline in-situ chemosynthesis technology are combined together, so that the washability of phytic acid is improved, and the electric conduction and flame-retardant stability and durability of the cotton fabric are improved.
Description
Technical field
The present invention relates to a kind of function cotton fabric preparation method, especially a kind of method utilizing cationic polyacrylamide layer assembly phytic acid to prepare function cotton fabric.
Background technology
Along with the progress of science and technology, more electric equipment products enter into the life of people, have brought electromagnetic pollution, are called that the 4th after atmospheric pollution, water pollutions and sound pollution pollutes greatly. Human body is by after excessive electromagnetic wave radiation, blood, lymph liquid and cellular plasm can change, cause that the thymus nucleic acid in cell is impaired and gene are undergone mutation and lopsided, and then bring out leukemia and tumour, also can cause placenta chromosomal change, cause the deformity of baby or the spontaneous abortion of pregnant woman.
Conductive polymers is the organic polymer with controllable conductivity, and especially polyaniline has been widely used in conduction, electromagnetic shielding, antistatic, the field such as anti-corrosion of metal, opto-electronic device, gas-sensing probe, super capacitor. Utilize in situ chemical oxidation technology polyaniline can be coated on textile surface, especially cotton fibre surface, thus make nonconducting cotton fabric have electroconductibility. Polyaniline regulates and controls electroconductibility by doping usually, and conventional doping agent is proton acid. The current coated cotton fabric of published polyaniline mainly adopts some small molecular organic acids to adulterate, the easy dedoping of dopant acid in washing process and lose electroconductibility.
Phytic acid is a kind of polyphosphoric acid, as sequestrant, antioxidant, preservation agent, water-softening chemicals, fermentation accelerant, anticorrosive metal agent etc., it is widely used in the industry fields such as food, medicine, paint, coating, daily-use chemical industry, anti-corrosion of metal, textile industry, plastics industry and polymer industry. Phytate molecule is with 6 electronegative phosphate groups, it is possible to for the doping of polyaniline, and cotton fibre has good flame retardant effect; Phytate molecule has coplanarity, and avidity is relatively big, electronegative, it is possible to be adsorbed on fiber surface by the layer assembly effect with cationic polyacrylamide so that it is have good washing fastness.
Summary of the invention
Technical problem to be solved by this invention is, for the shortcoming that above prior art exists, a kind of method utilizing cationic polyacrylamide layer assembly phytic acid to prepare function cotton fabric is proposed, this preparation method is simple, prepare the cotton fabric and there is good electroconductibility and flame retardant properties, there is the advantages such as washing fastness simultaneously.
Following technical scheme is taked in order to realize above-mentioned purpose the present invention.
A kind of method utilizing cationic polyacrylamide layer assembly phytic acid to prepare function cotton fabric provided by the invention, this preparation method comprises the steps: that 0.2-1g cationic polyacrylamide is dissolved in 100mL water by (1), add cotton, under room temperature, soak 30min, take out and dry; (2) cotton of above-mentioned process being placed in the 100mL phytic acid aqueous solution, phytic acid concentration of aqueous solution is 5-10g/L, soaks 30min under room temperature, takes out and dries; (3) repeatedly step (1), (2) for several times; (4) it is cooled to 0-5oC, adds 2-5mL aniline; (5) slowly drip the 20mL aqueous solution added containing 5-7g ammonium persulphate, after having dripped, leave standstill 30min; (6) cotton fabric after above-mentioned process is taken out, washing, oven dry.
The useful effect of the present invention is, this technology of preparing is as phytic acid sorbent material using cationic polyacrylamide, phytic acid is enriched in cotton fibre surface by layer assembly, based on this by aniline in-situ polymerization on cotton fibre surface, makes cotton fabric have conduction and flame retardant properties; Cationic polyacrylamide is combined with polyaniline in-situ chemical synthetic technology with the laminated assembling technology of phytic acid, add the washing fastness of phytic acid, it is to increase cotton fabric conduction, fire-retardant stability and persistence.
