Flexible composite fabric with knitted structure and protection function

The invention relates to a composite fabric with a knitted structure and a flexible protection function, and relates to the field of knitted fabrics. The composite fabric with the knitted structure and the flexible protection function is moderate and small in overall thickness, good in softness and comfort degree and good in breathability and protection effect; complicated steps such as sewing, pressing and hot flux bonding in a traditional subsequent process are abandoned, close combination of the double-layer structure is achieved only through natural connection between the coils and close knitting yarn, the overall stability of the fabric is enhanced through the design, the layering risk is greatly reduced, the fabric keeps the soft characteristic, and meanwhile the fabric has the good elasticity. Extremely high integrity is realized; according to the three-dimensional knitted fabric, the functionality of the inner layer and the functionality of the outer layer are ingeniously fused together through the we
