摘要:
A closure system and method of making a closure system for a disposable article. A substantially continuous closure system web is provided. One face of the web is provided with first fastening region at terminal end portion(s) of the web. A second fastening region, engagable with the first fastening region, is provided on a second face of the web in a region adjacent the terminal end portion(s). The closure system tab elements are cut from the web and attached to a second web, used in producing the disposable article, at longitudinally spaced locations. This second web is then cut at transverse cut lines separating the closure system tab element into two functional elements. A first functional element has a fastening tab portion and the second functional element has an attachment portion, The attachment portion of one closure system tab element interacts with a fastening tab portion of an adjacent closure system tab element to form a functional closure system on a disposable article made using the second web.

A storage/dispensing assembly, e.g., a roll or stack, of non-woven pressure sensitive adhesive tape comprising one or more multilayer sheets of pressure sensitive adhesive tape arranged such that the adhesive layer in the assembly of an overlying non-woven pressure sensitive adhesive tape is in direct contact with the underlying nonwoven backing layer of non-woven pressure sensitive adhesive tape. The non-woven backing layer is formed at least in part of fibers having a denier of greater than 15 so as to decrease the level of fibers disengagement when an overlying nonwoven pressure sensitive adhesive tape is removed from the assembly.

A fastening tab for a disposable diaper having a second half 3 with a maximum width y and a first half 2 with a minimum width x. Side edge portions are provided with no sharp corners. First half side edges (7 and 7') and the adjacent second half side edges (8 and 8', respectively) are inverted mirror images of each other taking the transverse line 10 which separates the two halves (2 and 3) as the plane of reflection. Using the bisecting longitudinal center line 12 as the plane of reflection a first side edge (7 and 8) is a mirror image of the opposing side edge (7' and 8'). The tape provides a maximum peel front at the distal end of the attached fastening tab providing a more secure closure and is capable of being cut from a stock roll in a repeating pattern without any waste.

A disposable tape tab for a diaper or a like article is provided with at least a fastening tape tab portion and a release tape tab portion, the fastening tape tab portion having a fastening surface which fastening surface is on a face opposite the adhesive surface face of the release tape tab portion. The fastening tape tab portion and said release tape tab portion are joined by at least one adhesive-to-substrate bond with no adhesive layer to adhesive layer contact. Preferably the fastening surface on the fastening tape tab is a pressure sensitive adhesive, with both the fastening tape tab and the release tape tab having a release layer on the face opposite the face having the adhesive layer.
摘要:
Pressure sensitive adhesives comprising an acrylate polymer and surface-modified nanoparticles are described. The surface-modified nanoparticles comprise a nanoparticle having a silica surface and surface modifying groups covalently attached to the silica surface. At least one surface-modifying group is a polymeric silane surface modifying group. At least one surface-modifying group is a non-polymeric silane surface modifying group. Methods of preparing such adhesives, including their exposure to UVA and UVC radiation are also described.

Methods of reducing tack of edge faces of a roll of an adhesive coated substrate. The method includes reducing tack of the edge faces by subjecting the edge faces to a radiation source with radiant output at a wavelength of less than 200 nanometers.
摘要:
Release compositions comprising a blend of ethylenically unsaturated fluoroorganopolysiloxane polymers and ethylenically unsaturated non-fluorinated organopolysiloxane polymers are described. The release compositions are dispersed in a solvent system and also contain a catalyst and at least one crosslinker. Both fluoroorganohydrogenpolysiloxane and organohydrogenpolysiloxane are described. Release liners and adhesive articles including cured release compositions are also disclosed.

There is provided a laminate of a thermoplastic backing to a fibrous web. This laminate, for example, could be used as a loop laminate for use in a hook and loop fastening system or an intermittently bonded elastic fibrous laminate. The laminate comprises a thermoplastic backing layer, having a first face and a second face. The backing layer has a plurality of projections extending from at least the first face of the backing. A fibrous web is attached to the backing at the location of at least some of the projections. The thermoplastic material of the backing, at the location of the projections, penetrates into the fibrous web encapsulating at least in part fibers of the fibrous web. The fibrous web preferably penetrates into at least some of the projections. The fibrous web is generally not attached, or very lightly attached, to the backing layer over at least some portion of the distance between adjacent projections. This allows for a low cost fibrous web laminate that can be directly extrusion formed with a backing without compromising the fibrous web's performance between the attached projections.

Methods of making hydrophobic aerogels are described. Disclosed methods include forming a surface-modified metal oxide aerogel precursor from a sol comprising a solvent, a metal oxide precursor, and a hydrophobic surface modifying agent. The resulting modified precursor can be dried to from hydrophobic aerogels. Methods of forming the surface-modified metal oxide aerogel precursor include hydrolyzing the metal oxide precursor and co-condensing the hydrolyzed metal oxide precursor and the hydrophobic surface modifying agent. Hydrophobic aerogels and hydrophobic aerogel articles are also disclosed.
