摘要： Nonwoven fabrics and fabric laminates are formed from continuous filaments or staple fibers of a select blend of specific grades of polyethylene and polypropylene which give improved fabric performance not heretofore recognized or described, such as high abrasion resistance, good tensile properties, excellent softness and the like. Furthermore, these blends have excellent melt spinning and processing properties which permit efficiently producing nonwoven fabrics at high productivity levels. The polymers are present as a lower-melting dominant continuous phase and at least one higher-melting noncontinuous phase dispersed therein. The lower-melting continuous phase forms at least 70 percent by weight of the fiber and comprises a linear low density polyethylene polymer of a melt index of greater than 10 and a density of less than 0.945 g/cc. At least one higher-melting noncontinuous phase comprises a polypropylene polymer with melt flow rate of greater than 20 g/10 min.

摘要： The invention is directed to composite nonwoven fabrics and processes for producing the same. The fabric includes a layer of inelastic continuous or staple fibers formed from a blend of polyethylene and polypropylene laminated to an extensible web, such as a polyolefin film. Preferably, the composition of the fibers ranges between 5 to 50 percent by weight of polypropylene with the balance made up of polyethylene. The nonelastic fibers are capable of being highly elongated upon mechanical stretching without adversely impacting fiber tie down. Accordingly, a smooth, strong, coherent fabric is obtained, which is especially well suited for incorporation into disposable absorbent articles such as diapers, training pants, incontinence briefs and feminine hygiene products.

摘要： The invention is directed to a composite nonwoven fabric comprising first and second nonwoven webs of spunbonded substantially continuous thermoplastic filaments, and a nonwoven hydrophobic microporous web of thermoplastic meltblown microfibers sandwiched between the first and second nonwoven webs. The filaments of the nonwoven spunbond webs are formed of continuous multiconstituent filaments which include a lower melting gamma radiation stable polyethylene polymer component and one or more higher melting gamma radiation stable polymer constituents, wherein a substantial portion of the surfaces of the multiconstituent filaments consists of the lower melting gamma radiation stable polyethylene constituent. The nonwoven hydrophobic microporous web is formed from a gamma radiation stable polyethylene polymer. The webs are bonded together to form the composite nonwoven fabric by discrete point bonds in which the polyethylene constituent of said multiconstituent filaments and the polyethylene of said third nonwoven web are fused together.

摘要： Tufted carpets which are conformable and stretchable make use of a stretchable carpet backing formed from a composite fabric. The stretchable carpet backing fabric is formed of a stretchable elastic net and at least one nonwoven fibrous layer overlying the stretchable elastic net. The fibers of the fibrous layer extend through said elastic net to mechanically secure the fibrous layer to the elastic net and form a unitary coherent elastic fabric.

摘要： The present invention relates to compositions such as fibers, elastic yarns, wovens, nonwovens, knitted fabrics, fine nets, and articles produced at least in part from a styrenic block copolymer comprising at least two blocks produced from vinyl aromatic monomers and at least one block produced from alkyl-substituted, conjugated alkene monomers, where the block produced from the conjugated alkene may have sufficient substitution so as to prevent or significantly minimize thermal cross-linking of the residual unsaturation in the formed block during fiber formation. Additionally, the composition may be described as processable, without requiring any additives if, for example, the order-disorder-transition (ODT) temperature is less than about 280° C.

摘要： A nonwoven fabric having high performance aqueous fluid retention and wiping characteristics and a method of producing such fabric. The fabric comprises a reinforcing web of self-bonded continuous filament synthetic fibers having at least one surface with spaced clusters of synthetic staple fibers and short natural fibers generally surrounded by void areas having a concentration of synthetic staple fibers and short natural fibers which is lower than such concentration in the clusters. The desired pattern of clusters may be obtained by hydroentanglement using a coarse apertured forming surface.
