A duckbill mask includes a mask upper side and a mask lower side. A manufacturing process includes: respectively performing edge folding and press sealing on an upper nose edge on the mask upper side and a jaw edge on the mask lower side, and using a double-way staggered cutting process to add a nose bridge while folding the upper nose edge; and overlapping the mask upper side and the mask lower side, then performing press sealing on convex edges of the mask upper side and the mask lower side by using a staggered opposite arrangement method, and using a double-way staggered cutting process to add an ear belt while performing press sealing on the convex edges. In the multi-line machining process, multi-line edge folding and press sealing of all layers of materials, overlapping and then finished product cutting are performed, whereby two duckbill masks are manufactured at a time.

Aspects herein are directed to a composite nonwoven textile that includes non-linear entangled seams and method and systems for producing the same. The composite nonwoven textile includes at least a first nonwoven layer, a second layer, and a fill material positioned between the first nonwoven layer and the second layer. When the composite nonwoven textile is formed into a garment, the regions between the non-linear entangled seams may help store and retain heat to provide insulation, and the non-linear entangled seams may help prevent shifting or drift of the fill material.
