  • Patent number: 9750651
    Abstract: An absorbent article (20) having an absorbent core comprising at least about 80% of superabsorbent polymers (SAP) by weight of its absorbent material. An acquisition-distribution system (ADS) (50) is at least partially disposed between the absorbent core and the topsheet. The ADS extends in the longitudinal direction of the absorbent article at least from a point A1 disposed at a distance D from the front edge to a point A2 disposed at a distance D from the back edge of the article, D being equal to 32% of the length L of the article. The ADS has a basis weight which may be at least 20% lower at the point A2 than at the point A1.

  • Patent number: 9573308
    Abstract: A meltblown method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse prepared bio-polyamide 6,10 into a melt, then extrude, and blow the melt out spinnerets to form natural bio-polyamide 6,10 filaments laid onto a conveyer to form a substrate fibrous web. Secondly, blend and dissolve prepared pulp by putting N-methylmorpholine N-oxide (NMMO) dissolving solvent, and dehydrate it to form dope, then extrude and blow the dope out spinnerets to form natural cellulose filaments laid up over existing fibrous web of bio-polyamide 6,10 on the conveyer so that a fibrous composite of the bio-polyamide 6,10 and natural cellulose in overlaid lamination is formed thereon. Finally, coagulate and regenerate the fibrous composite of the bio-polyamide 6,10 and natural cellulose by means of ejecting mist aerosol of water, and convert it into nonwoven fabric with hygroscopic metastatic feature by orderly applying post treatments of hydro-entangled needle punching, drying, winding-up processes.
