    Abstract: There is provided an apparatus and methods for stretching one or more zones (26, 27) of a web and webs including one or There is provided an apparatus and methods for stretching one or more zones of a web and webs including one or more stretched zones. Each of the stretched zones in the web is stretched in the cross-web direction, i.e., the direction (c, d) transverse to the downweb direction (m, b). The stretching can be performed continuously on the web as the web is advancing through the apparatus in the down-web direction. The method for stretching an extensible web in the cross direction generally is practiced on a substantially continuous cross-directional extensible web. The web is traveling in a first downweb direction at a first speed. The extensible web has a width and substantially continuous length in the first downweb direction. The crossweb stretching occurs in an orientation zone (26, 27) established between at least two moving nip points (28, 29, 30). The nip points are in a plane of the web with a leading nip (28) downweb of a trailing nip (29, 30) with the at least two nips offset in the cross direction. The leading nip moves at a faster speed than the trailing nip, where the degree of crossweb orientation in the orientation zone is proportional at least to a ratio of the leading nip speed to the trailing nip speed.

    Abstract: 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.

    Abstract: Melt-processable polydiorganosiloxane polyurea segmented copolymer compositions are provided. The compositions comprise alternating soft polydiorganosiloxane units and hard diisocyanate residue units, the diisocyanate residue being the diisocyanate minus the -NCO groups, the units being connected together by urea linkages which also provide hard units. The compositions are prepared by continuously providing at least one diisocyanate and at least one polydiorganosiloxane diamine to a reactor, mixing the diisocyanate and the polydiorganosiloxane diamine in the reactor under substantially solvent-free conditions, allowing the diisocyanate and polydiorganosiloxane diamine to react to form a polydiorganosiloxane polyurea copolymer, and conveying the copolymer from the reactor.
