Spunlace non-woven fabric production line and production process thereof

The invention discloses a spunlace non-woven fabric production line and a production process thereof. The production line comprises a primary opening mechanism, a large bin, fine opening mechanisms, air pressure cotton boxes, a carding machine, a secondary carding machine, a cross lapping machine, a buffer mechanism, a drawing machine, a spunlace entanglement machine, a drying machine, a scanningdetector and a winding machine. The equipment communicates with a high-pressure pump through a conveying pipeline; the output end of the primary opening mechanism communicates with the large bin; andthe output end of the large bin communicates with two fine opening mechanisms, the two fine opening mechanisms are respectively connected with the air pressure cotton boxes, one air pressure cotton box sequentially communicates with the carding machine, the cross lapping machine, the buffer mechanism, the drawing machine, the secondary carding machine, the spunlace entanglement machine, the dryingmachine, the scanning dete
