Technical Field

The utility model relates to the technical field of non-woven fabric production, in particular to an antibacterial composite non-woven fabric.

Background

Non-woven fabric, also called non-woven fabric, is a kind of cloth-like material produced by treating various fiber raw materials with a needle-punching machine or a carding machine and forming or bonding them under high pressure. The non-woven fabric has no warp and weft, is very convenient to cut and sew, is light and easy to shape, and is popular with hand fans. Because it is a fabric formed without spinning a woven cloth, it is formed by simply orienting or randomly arranging textile staple fibers or filaments to form a web structure and then reinforcing them by mechanical, thermal or chemical means. It is not formed by interweaving and knitting yarns one by one, but the fibers are directly bonded together by a physical method. The non-woven fabric breaks through the traditional spinning principle and has the characteristics of short process flow, high production speed, high yield, low cost, wide application, multiple raw material sources and the like.

The non-woven fabrics of production now only adopts the intensity of single fibre web reinforcing non-woven fabrics when using for the intensity of non-woven fabrics is lower, and tensile strength is relatively poor, can't satisfy complex environment's user demand, and current non-woven fabrics antibacterial effect is relatively poor, leads to it when in-service use, adheres to easily and breeds more bacterium, influences user's healthy.
