METHOD OF MAKING A SPUNBOND NONWOVEN LAMINATE
A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.
Absorbent Structure for Items of Clothing, Operating Method and Uses Thereof
A clothing item absorbing structure, in particular to a washable and reusable structure, for the absorption of body fluids in which at least a set of four overlapping layers are provided. A first layer has high density and porosity synthetic fibers suitable for the entry of body fluids. A second layer has a combination of hydrophilic and hydrophobic fibers with a plurality of protruding channels for dispersing body fluids. A third layer of cellulosic fibers neutralizes odors and absorb moisture. A fourth layer has a polymer, microporous and liquid impermeable membrane. And a strip connects along the periphery of said set of layers, wherein the strip together with the fourth layer seals said set of layers to prevent leakage of body fluids. In certain embodiments, the disclosure relates to underwear that incorporates the absorbing structure.
Nonwoven Fabrics Including Recycled Polypropylene
Nonwoven fabrics are provided that include a first meltblown layer, in which the first meltblown layer comprises a first polymeric material including (i) a first polymer component and (ii) optionally one or more first additives. The first polymer component comprises a first recycled-polypropylene (rPP).
Hot melt adhesive compositions containing propylene copolymers and methods for using the same
A hot melt adhesive composition, which may be used as a construction adhesive in hygiene articles, comprises a first polymer comprising a unimodal copolymer of propylene and ethylene and having a weight average molecular weight of between about 5,000 and 60,000 daltons; a second polymer comprising a copolymer of propylene and ethylene and having a weight average molecular weight of at least 100,000 daltons; a tackifying resin having a Ring & Ball softening point of at most 115° C.; and a plasticizer. The composition demonstrates good peel strength and good shear resistance and is sprayable, with a sufficiently low viscosity, at low application temperatures, such as at about 121° C.
Method of Making a Tube and Tube
A method of making a tube (60) includes forming at least one tube layer (101, 106, 108); and forming at least one film layer (102, 103, 104) on the at least one tube layer, wherein the at least a portion of the at least one film layer does not completely overlap the at least one tube layer.
PERFORATED LAMINATED PRODUCT AND METHOD FOR PRODUCING THIS PRODUCT
A laminated product includes an extruded film of microperforated plastic material with a vacuum perforation process having protuberances extending in a same direction from a same face of the film, with first holes having an average diameter between 100 microns and 300 microns, produced at the vertices of the protuberances, and—a layer of nonwoven fabric mechanically joined by lamination to the film on the opposite face to that on which the protuberances extend, the laminated product being perforated with second through holes having an average diameter between 300 microns and 700 microns.
PRINTED BREATHABLE AND MICROPOROUS THIN THERMOPLASTIC FILM
Printed, breathable thermoplastic films, laminates, and methods of making films having a basis weight less than or equal to 15 gsm and a water vapor transmission rate of at least about 500 grams H.sub.2O/24-hour/m.sup.2, wherein the film has a ratio of the MD load at break to the CD load at break of less than about 10, and at least one of a machine-direction notched Elmendorf tear strength of at least about 5 g or a machine-direction notched trapezoidal tear strength of at least about 15 g.
Method of producing a multi-layered printed absorbent article
A method for producing a multi-layered absorbent article is disclosed. At least two of the layers include a colored region.
UNITARY NONWOVEN MATERIAL
