摘要： The present invention provides a method for forming preferably a unitary polymeric hook fastener (20) comprising a flexible backing (11), and a multiplicity of spaced hook members (24) projecting from the upper surface of the unitary backing (11) wherein each hook member (24) comprises a multiplicity of hook head elements (28, 29) projecting in substantially the same direction. The hook members each comprise a stem portion (25) attached at one end to the backing (11), and a head portion (28, 29) at the end of the stem portion (25) opposite the backing (11). The head portion (28, 29) can also extend from a side of a stem portion (25) or be omitted entirely to form alternative projections which can be other forms than a hook member. The head portion (28, 29) preferably projects past the stem portion (25) on at least one of two opposite sides. At least the hook head portions (28, 29) have two or more hook head elements (28, 29) on at least one of the two opposing sides of the stem (25). The hook head portions (28, 29) preferably have been heat treated so as to decrease the hook head thickness and thereby reducing or eliminating molecular orientation in at least the hook head in the machine direction.

摘要： There is provided a loop laminate for use in a hook and loop fastening system or a hook and loop fastening system. The loop laminate first comprises a backing layer, having a first face and a second face. The backing layer has a plurality of elevated projections extending from at least the first face of the backing layer wherein some of the projections extend by a distance of at least 50µm. A loop material is attached to at least some of the projections such that said loop material is raised off the backing layer over at least some portion of the distance between adjacent attached projections to allow for hook heads of hooks to easily penetrate the loop material. The hook fastening material has hooks that are arranged in a manner so as to not substantially engage the projections when the hook fastener is engaged with the loop laminate.

摘要： There is provided a coextruded film or film layer comprises at least two sets of regions, a first set of regions formed predominately of a first thermoplastic polymer and a second set of regions formed predominately of a second thermoplastic polymer arranged in an alternating side-by-side manner. These side-by-side polymer regions generally extend in a machine direction in a continuous manner. The film or film layer has a first face and a second face. On at least one face, one of the regions of the first thermoplastic polymer bridges over the adjacent lane of another (the second thermoplastic polymer region or a third thermoplastic polymer region) thermoplastic polymer region creating on the first face a continuous layer of the first thermoplastic polymer. The opposite face comprises at least in part the other thermoplastic polymer. This bridging layer of the first thermoplastic polymer maintains the integrity of the film or film layer in the cross direction to the machine direction without the need for compatibilizers or tie layers, and allows for the other thermoplastic polymer regions to be exposed on the second face.

摘要： A method for coextruding an initial melt stream through at least one profiled die inser (2), which is shaped to form a nonlinear melt stream from the incoming initial melt tream. The die insert inlet (12) has a nonlinear opening between an upper boundary and a lower boundary. The die insert (2) is positioned so as to redirect the flow of one or more of the melt streams or regions of the incoming melt stream. The initial melt stream at the die insert inlet (12) is generally redirected in the cross direction to the original flowpath of the material melt stream. The nonlinear melt stream formed at the die insert inlet (12) then converges within the die insert (2) into a substantially more linear or rectangular melt flow stream at the die insert outlet opening. At the die insert outlet opening at least one layer or portion of the initial melt stream has been partitioned, into different proportions in different zones in the width or cross direction of the extruded proportions in different zones in the width or cross direction of the extruded material. The invention is also directed at the extruded articles.
