SPUNBOND NONWOVEN LAMINATE AND METHOD OF MAKING SAME
A spunbond nonwoven laminate has a stack of at least two and at most four spunbond nonwoven layers each formed by or consisting of crimped continuous filaments. A degree of crimping of the filaments in each of the spunbond nonwoven layers is different from a degree of crimping in each of the other spunbond nonwoven layers and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments each having at least one first plastic component and at least one second plastic component with each of the plastic components being present in the respective filament in a proportion of at least 10 wt %.
Carded staple fiber nonwovens
A carded staple fiber nonwoven having a basis weight of between about 45 grams per square meter (gsm) and about 150 gsm, includes a blend of absorbing fibers, stiffening fibers and filler fibers. The carded staple fiber nonwoven is non-heat stiffened, has an air permeability of between about 100 m.sup.3/m.sup.2/min and about 500 m.sup.3/m.sup.2/min, and a pore radius mode of between about 60 m and about 120 m.
METHOD FOR MANUFACTURING SHORT FIBERS, METHOD FOR MANUFACTURING NONWOVEN FABRIC, SHORT FIBER MANUFACTURING DEVICE, AND NONWOVEN FABRIC MANUFACTURING DEVICE
A method for manufacturing short fibers includes relaxing entanglement of crimped cellulose acetate fibers in a tow band by applying a tension in a predetermined transfer direction to the tow band transferred in the transfer direction, the tow band containing the crimped cellulose acetate fibers and being impregnated with moisture, and forming short fibers by cutting the tow band in which the entanglement is relaxed.
Nonwoven fabric layered body, composite layered body, and cover sheet
A nonwoven fabric layered body includes a first nonwoven fabric layer including a crimped fiber (A), which is a fiber made of a thermoplastic polymer and which has an average crimp diameter of 800 ?m or less; and a hydrophilic agent.
NONWOVEN LAMINATE FABRIC COMPRISING MELTBLOWN AND SPUNDBOND LAYERS
The invention relates to a nonwoven laminate fabric comprising a meltblown nonwoven layer sandwiched between first and second spundbond nonwoven layers, wherein at least one of the spundbond layers is a high loft spunbond nonwoven layer comprising or consisting of crimped multicomponent fibers.
MELT-BLOWN FIBER WEB HAVING IMPROVED ELASTICITY AND COHESION, AND MANUFACTURING METHOD THEREFOR
The present invention relates to a melt-blown fiber web having improved elasticity and cohesion, and a manufacturing method therefor. The objective of the present invention is accomplished by a melt-blown fiber web comprising a thermoplastic resin which comprises 10 to 60 wt % of thermoplastic resin microfibers and 40 to 90 wt % of non-circular cross-sectional hollow conjugated staple fibers with respect to the total weight of the fiber web.
MULTI-LAYERED ABSORBENT MATERIAL

The absorbent material can include a saturation capacity greater than 125 grams, and a second intake time of less than 50 seconds and a wet thickness of less than 17 mm according to the Modified Fluid Intake Under Pressure Test as described herein. In some aspects, the intake layer and the absorbent layer can provide an integrated material including an interface between the intake layer and the absorbent layer. The interface can include at least some fibers of the intake layer mixed with at least some fibers of the absorbent layer.
ABSORBENT SUBSTRATES WITH HIGH PERCENTAGES OF SUPERABSORBENT MATERIAL AND METHODS OF FORMING THE SAME
Absorbent substrates including a high percentage of superabsorbent material and method of manufacturing such absorbent substrates are disclosed. An absorbent substrate can include an intake layer including a first plurality of fibers and an absorbent layer. The absorbent layer can include superabsorbent material providing greater than 80% of the absorbent layer by total weight of the absorbent layer. The intake layer and the absorbent layer can provide an integrated material including an interface between the intake and absorbent layers. The interface can include at least some of the first plurality of fibers of the intake layer mixed with at least some of the absorbent layer.
DURABLE PILLING RESISTANT NONWOVEN INSULATION
Provided is batting that includes a bonded nonwoven web made from a fiber mixture containing: (a) 20 to 55 wt % of siliconized fibers having a denier of 1.5 to 10.0 and a length of 51 mm to 84 mm; (b) 10 to 45 wt % of hollow conjugate fibers having a spiral crimp, and having a denier of 1.5 to 10.0 and a length of 51 to 84 mm; (c) 10 to 45 wt % of a first population of binder fibers which are elastomeric co-polyester binder fibers having a denier of 1.5 to 8.0, a length of 51 mm to 84 mm, and a bonding temperature of 110?
