As shown in fig. 11, the present invention further provides a method for embedding yarns in a fiber web by using the manufacturing apparatus of the above embodiment 2, the method comprises drawing the parallel arranged warp yarns 12 through the fiber web 13 by the knitting needle 21, forming the loops 14 by the aid of the thread hooking device 315, introducing the weft yarns 15 in the direction perpendicular to the parallel arranged yarns, returning the thread hooking device 315 after the weft yarns are introduced into the loops 14, moving the knitting needle 21 downwards, straightening the warp yarns 12 and pressing the weft yarns 15 to form one-time embedding.

Finally, the yarn-embedded multilayer non-woven fabric can be obtained after multiple embedding.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
