Problems solved by technology

However, the magnetic powder is bonded to the surface of cotton fiber by adhesive, which reduces the skin affinity of cotton fabric to the human body; the modified magnetic fluid adsorbs cotton fiber mainly through intermolecular van der Waals force and ionic bond force, and the washing fastness is relatively low. Low

Abstract

The invention provides a preparation method of magnetic cotton fabric. The method comprises the following steps: (1) preparation of a magnetic dissolving solution: cooling an aqueous solution containing sodium hydroxide and urea to minus 10 DEG C, adding magnetic particles, violently stirring at low temperature to prepare a magnetic dissolving solution; (2) carrying out dip padding on cotton fabric in the magnetic dissolving solution obtained in the Step (1) for many times; and (3) impregnating the cotton fabric which has undergone dip padding into an aqueous solution containing sulfuric acid and sodium sulfate to be solidified for 10 min, washing and drying. The preparation technology is simple and practicable, and preparation cost is low. The prepared cotton fabric has lasting magnetism, and surface properties of cotton fiber will not be changed. During the preparation process, no adhesive is used. The product is nontoxic and harmless.

Description

technical field [0001] The invention relates to a method for preparing functional fabrics, in particular to a method for preparing magnetic cotton fabrics. Background technique [0002] Modern medicine shows that a weak magnetic field can increase people's excitability and present an active response. The magnetic lines of force at the acupuncture points of the human body can penetrate these acupuncture points and play the same role as acupuncture in traditional Chinese medicine. Therefore wear such fabric to carry out all-round physiotherapy of human body at any time. Based on this principle, the textiles produced by using magnetic fibers can adjust the functions of the human body, improve the ability of the human body to resist diseases, and play a role in medical care. [0003] At present, there are many methods for preparing magnetic fibers, such as: direct forming of metal fibers, blended spinning method, fiber surface modification method, etc. For natural cotton fibe...
