Problems solved by technology

For natural silk fibers, the method of impregnation is currently used to combine inorganic functional nanoparticles with silk fabrics. The far-infrared radiation rate and saturation magnetic field strength of the cotton prepared by this method are also good, but the durability needs to be improved.

Abstract

The invention discloses a novel magnetically-grafted silk fiber and a preparation method thereof. The method comprises the following steps: cleaning and activating the surface of the silk fiber; putting in a magnetic grafting solution, heating, oscillating and reacting so as to obtain the magnetically-grafted silk fiber. According to the method, a magnetic nanometer material containing iron and silver is dissolved in an acidic salt buffering solution to activate the surface of a magnetic material; by an assistant effect of a triggering agent, the magnetic material is grafted to the surface of the silk fiber. The preparation method has the advantages of increasing the utilization rate of the magnetic material, saving energy, protecting environment and easily achieving industrial production. The prepared silk fiber is good in magnetic property, retains the gloss and soft hand feeling of silk and is good in water washing property.

Description

Technical field: [0001] The invention belongs to the technical field of silk products, in particular to a novel magnetically grafted silk fiber and a preparation method thereof. Background technique: [0002] Magnetic fiber is a new type of functional fiber material, and magnetic textile fiber is a material with both textile fiber properties and magnetic properties. The products made of magnetic textile fibers are uniformly arranged with permanent magnet particulate materials. The countless magnetic force lines formed by these particulate materials are interwoven into a three-dimensional magnetic force line network, which can play a very good role in health care, such as anti-inflammatory and swelling, and improve blood microcirculation. , Activate cell metabolism, high far-infrared emission rate, soft and comfortable to wear, easy to clean, it is the darling of daily medical care. [0003] Magnetic synthetic fibers are mostly made of functional magnetic materials and carri...
