Abstract
The invention discloses a nano non-woven fabric based on a nano cellulose antibacterial material and a preparation method thereof, wherein the preparation method comprises the following steps: the nano-cellulose antibacterial fabric comprises a middle nano-nonwoven base fabric and a nano-cellulose antibacterial layer based on a nano-cellulose antibacterial material, wherein the nano-cellulose antibacterial layer is arranged on the upper surface and the lower surface of the nano-nonwoven base fabric, and a non-woven surface layer fabric for preventing adhesion is further arranged on the outer side of the nano-cellulose antibacterial layer. The nano non-woven fabric prepared from the nano cellulose antibacterial material has an obvious antibacterial effect, is soft and comfortable, and is suitable for the field of multipurpose weaving.
Description
Technical Field
The invention relates to the technical field of nano non-woven fabrics, in particular to a nano non-woven fabric based on a nano cellulose antibacterial material and a preparation method thereof.
Background
The antibacterial fabric has good safety, can efficiently and completely remove bacteria, fungi and mould on the fabric, keeps the fabric clean, and can prevent bacteria from regenerating and propagating; with the improvement of living standard, the suppression or elimination of harmful germs has become a focus of attention.
The mainstream treatment methods in the market at present have two types: one is a built-in silver ion antibacterial fabric, and an antibacterial agent is directly made into chemical fibers by adopting a spinning-grade antibacterial technology; the other is a post-treatment technology, namely the post-shaping technology of the fabric is added, the post-treatment technology is relatively simple, the cost is easy to control according to the specific requirements of customers, and the fabric is the most applied fabric in the market.
The nano-cellulose is used as a novel nano-material, has the characteristics of high strength, large specific surface area, degradability, high biocompatibility, reproducibility and the like, and can be used as a base material to be combined with nano-silver to obtain a nano-cellulose antibacterial material, so that if the nano-cellulose is used for developing an antibacterial fabric for cloth, or the further development of the antibacterial fabric can be promoted.
