In order to secure the guide wire in a flat and straight state and to be embedded in the two-layer fiber net, the lapping step of this embodiment can not but use the parallel wrapping method.

Referring to Figure 16, this embodiment provides a correspondingly different nonwoven gauze product. The nonwoven fabric gauze product is manufactured in accordance with the method provided in this embodiment. The distinguishing point from the first embodiment is that a guide wire 901 is embedded between two spunlaced nonwoven fabrics, The fibers are embedded between the fibers of the spun lace nonwoven fabric and covered with the entangled fibers. The number of lead wires embedded may be one or plural. In Fig. 16, reference numeral 902 denotes a nonwoven fabric layer.

Further, the metal yarn may be a continuous copper wire or a copper wire section in which a plurality of strands are connected to each other. In the case where the metal yarn has a plurality of strands in the front and rear of each other, the chip may be installed at the center of the copper line when only one chip is installed in each copper wire. The chip 904 can emit an electromagnetic wave signal, wherein each chip corresponds to one independent sequence number and detects it through a receiver that receives the electromagnetic wave signal in a wireless manner. The distance between the two chips can be set according to actual demand, for example, 29 cm. The chip is bonded to the metal yarn by a conductive adhesive, and the metal yarn can act as an antenna, thereby increasing the sensing distance of the chip.
