A kind of antibacterial knitted fabric and its production process

technical field

The invention relates to the technical field of knitted fabrics, in particular to an antibacterial knitted fabric and a production process thereof.

Background technique

With the continuous progress and innovation of fabric weaving technology, functional knitted fabrics occupy an increasingly important position in the market. Functional knitted fabric refers to the ability to endow the fabric with one or more functions. The performance of the fabric made of the current fabric fiber mainly depends on the properties of the fiber itself. For example, most natural fiber materials have good hygroscopicity and softness. Fiber materials also have antibacterial and antibacterial effects, while chemical fibers mostly have effects such as crispness and shaping, which are the properties of fiber materials themselves. Consumers' health and antibacterial awareness is constantly increasing, and in the use of fabrics, antibacterial and antibacterial fabrics are more in line with the needs of use, in order to obtain a fabric with good antibacterial function. In view of this, we propose an antibacterial knitted fabric and its production process.
