Composite webs having one or more polymeric structures located on a substrate, closure systems comprising composite webs, and methods of attaching articles are disclosed. The polymeric structures are formed using thermoplastic compositions and are attached to a surface of a substrate. The polymeric structures include an area that is attached to the substrate and a detached area that is not attached to a surface of a substrate.

A polyimide film F is brought into an intimate contact with a molding die 3 having a concave molding surface 3a so as to tightly close the open end thereof, and the polyimide film F is bent to deform only by the pressure difference of gas while being heated in a contactless manner. Molding is conducted by applying depressurization for a space 8 on the side of the molding die 3 relative to the polyimide film F while pressurizing the space 9 on the opposite side for the pressure difference at least in the final stage of the bending deformation so as to be in intimate contact with the concave molding surface 3a.
摘要:
A method is provided for forming a body for a hard disk carriage assembly from polyphenylene sulfide 40% glass fill. An injection mold is heated to approximately 130null C.; then a volume of polyphenylene sulfide 40% glass fill is injected into the mold to form the body of the carriage assembly. The polyphenylene sulfide 40% glass fill is then cooled within the mold for approximately 45 seconds before the body is ejected from the mold cavity. The body is then heated to approximately 130null C. for at least 2 hours in a post-bake operation.
摘要:
The present invention provides a fastener strip having magnetic powders which are not located across a whole volume of a strip but are incorporated in each discrete distinct area of the strip. The fastener strip has a base plate and many hook pieces which rise from a fastening surface of the base plate. Further, the fastener strip has a magnetic body in a row which rises from the surface of the base plate as well as is located below a substantially center line of the fastener strip. The magnetic powders are incorporated in the magnetic body and a part of the base plate located below the magnetic body, and the magnetic powders are not dispersed across the whole area of the base plate. A method of manufacturing such a strip is also described here.
摘要:
This invention relates to a tampon applicator, having a specific insertion tip structure with overlapping petals, connected to a tube. The petals are preferably curved such that one edge of a petal has an angle with the top edge of the tube of 40null to 60null. The petals are at least partially closed over the tampon and easily openable in use, which provides an improved, safer and more hygienic insertion of the tampon into the body.
摘要:
Device to produce polyurethane articles (37) covered by a film (19), including a mold (30) comprising a female part (13) and a male part (12) defining a molding cavity (18) inside which polyurethane material (24) is able to be injected. The device also comprises, in association with the perimeter edge of said female part (13), means able to exert a connection function in substantial cooperation with the zone of discontinuity between said female part (13) and said male part (12). The means comprise a movable annular ring-nut (22) including a first position (22a) to load a segment of said film (19) in order to insert said segment inside the mold, and a second position (22b) at least partly overlapping on the perimeter of said female part (13) in order to cooperate with said female part (13) during the molding of said polyurethane material (24).
摘要:
The invention is addressed to the problem of providing a method whereby a mixing of bulk material containing fibers (fiber material) and plastic granules for the plasticate extrusion of long fiber reinforced thermoplastics (LFT) will be possible during the melting process with high production outputs and with minimized material content in the extruder system and minimized fiber damage, and to the problem of creating an apparatus with an extruder for the practice of the method, which will have an extruder housing of modified geometry as to the feed opening and the corresponding screw elements, so that the disadvantages described above are avoided.
摘要:
Nonwoven substrates suitable for use as wet wipes are disclosed. The nonwoven substrates comprise at least one first region and at least one second region. The second region comprises reinforced protruding elements. In a preferred embodiment, the second region of the nonwoven substrate is reinforced by means of thermal bonding during the creation of the protruding elements of the second region. A liquid can be added to the nonwoven substrate prior to packaging or prior to use to make wet wipes. The reinforced second regions of the nonwoven substrates of the present invention make it possible to retain thickness of the wipe when wet without increasing the dry basis.
摘要:
A method for manufacturing an embossed surface comprising a polymer with a first glass transition temperature Tg1 comprises embossing the surface a temperature Temb; and raising the first glass transition temperature Tg1 of the embossed polymeric surface to a second glass transition temperature Tg2 such that Tg2>Temb. In another embodiment, a method for improving the release of a polymeric surface from an embossing tool comprises incorporating of one or more of fluorine atoms, silicon atoms, or siloxane segments into the backbone of polymer. The methods are particular suited for direct patterning of photoresists, fabrication of interdigitated electrodes, and fabrication of data storage media.
