Abstract: A method is provided for producing fine denier multicomponent thermoplastic polymer filaments incorporating high melt-flow rate polymers. Multicomponent filaments are extruded such that the high melt-flow rate polymer component is substantially surrounded by one or more low melt-flow rate polymer components. The extruded multicomponent filament is then melt-attenuated with a significant drawing force to reduce the filament diameter and form continuous, fine denier filaments.

Abstract: Repeated use of an adhesive-film laminate for bonds which can be redetached without residue by pulling on the laminate in the direction of the bond plane, the laminate employed comprising a) an elastic support with a resilience of at least 50% b) coated on at least one side with a solvent or hot-melt pressure-sensitive acrylate adhesive or dispersion pressure-sensitive acrylate adhesive.

Abstract: Extruded fibers and nonwoven webs made from the fibers are disclosed having improved cloth-like properties and an improved aesthetic appearance. The fibers used to form the webs are made from a thermoplastic polymer containing titanium dioxide and at least one mineral filler such as kaolin or calcium carbonate. In particular, the fillers are added in the amount so that the fillers become encapsulated within the polymeric material.

Abstract: Melt processable, flushable polymer fibers and methods of making melt processable, flushable polymer fibers are disclosed. The fibers comprise poly(ethylene oxide). Preferably, the poly(ethylene oxide) is modified by grafting polar vinyl monomers, such as poly(ethylene glycol) methacrylate and 2-hydroxyethyl methacrylate, onto poly(ethylene oxide). The modified poly(ethylene oxide) has improved melt processability and can be used to melt process poly(ethylene oxide) fibers of thinner diameters.

Abstract: An elastic laminate fabric useful for applications including apparel, sanitary products, and the like has an elastic vinylidene isoprene polymer film sandwiched between two outer non-woven layers. The laminate elastic fabric has CD elongation of at least 120%, and has recovery of at least 85% after several cycles of 100% elongation. A method of making the non-woven elastic laminate fabric includes extrusion coating a non-woven web having CD elongation of at least 120% with a vinylidene isoprene polymer film, and then thermocalendaring a second non-woven layer having a CD elongation of at least 120% to the exposed film surface. The mode of thermocalendering includes the use of an engraved calender roll having a discontinuous roll pattern and a land area no greater than 15%.

Abstract: A nonwoven has low tensile and high elongation in the first direction (typically the CD) and high tensile and low elongation in the second direction (typically the MD). The nonwoven has a plurality of bonding points defining a total bonding area along the second direction greater than along the first direction. Accordingly, the nonwoven has unbonded fiber portions and bonded fiber portions, with a bonded portion/unbonded portion ratio greater along the second direction than along the first direction. The bonding points are preferably either circular or oval in plan.
