Abstract

The invention discloses a highly water-absorbing antibacterial nonwoven fabric and a preparation method thereof, and relates to the technical field of nonwoven fabric preparation. In the present invention, ethyl tetrasilicate is used to react with nano-spherical ferric oxide, hexadecyltrimethylammonium bromide and silane coupling agent KH‑570, and then nano-spherical ferric oxide and hexadecyl Alkyltrimethylammonium bromide is used to prepare modified silica, and then the modified silica is coated with water-absorbing resin and nano-silver in sequence to prepare antibacterial microspheres, and then the acrylic resin is mixed with hydrophilic monomers, Add photoinitiator, ethyl acetate and antibacterial microspheres to obtain the treatment solution. Finally, add polypropylene non-woven fabric to the treatment solution. After mixing and impregnating, take out the polypropylene non-woven fabric, scrape off the excess treatment solution, and place it side by side. Cross-linking under ultraviolet light to obtain a highly water-absorbent antibacterial non-woven fabric. The non-woven fabric prepared by the invention has excellent water absorption and antibacterial properties.

Description

technical field [0001] The invention relates to the field of non-woven fabric preparation, in particular to a highly water-absorbing antibacterial non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. , Recyclable and so on. [0003] Non-woven fabric is a modern material industry with high technical content, wide market demand and wide range in the flexible material production system. It is developing at an astonishing speed and is known as the "sunrise industry" in the textile industry. Although non-woven fabrics produced by different processes have superior effects in improving the hygienic environment and facilitating use. However, human skin and clothes are places where bacteria breed. These bacteria use urea and other human excrement in sweat as a source of nutrition, continuously reprod...
