Process for Making a Porous Filter Element, Porous Filter Elements Made Thereby, and Filter Devices Including Them
The present disclosure relates more to processes for making a filter element that includes a filter membrane having a strip of thermoplastic polymer material laminated thereto, for example, as a strip along an edge of the filter membrane. For example, one such process includes providing a sheet of filter membrane having a first surface and an opposed second surface; providing a strip of thermoplastic polymer material having a first surface and an opposed second surface; contacting the first surface of the strip of thermoplastic polymer material with the first surface of the filter membrane; and softening the strip of thermoplastic polymer material at at least its first surface by irradiation with laser radiation; such that the softened polymer material of the first surface of the strip of thermoplastic polymer material bonds to the first surface of the filter membrane upon hardening.
THERMOPLASTIC RESIN FILM LAMINATE AND MOLDED ARTICLE COMPRISING THERMOPLASTIC RESIN FILM LAMINATE
Provided is a thermoplastic resin film laminate, which is obtained by ultrasonic welding of a thermoplastic resin film and a thermoplastic resin molded article, and which has high welding strength and excellent appearance with less welding marks. The above-described problem is solved by a thermoplastic resin film laminate which is obtained by bonding, by ultrasonic welding, a thermoplastic resin film having a thickness of 0.4 mm or less and a welding margin of a thermoplastic resin molded article having the welding margin and having a thickness of 0.5 mm or more, and wherein the height of the welding margin is 75-125% of the thickness of the thermoplastic resin film.
YARNS, THREADS, AND TEXTILES INCORPORATING A THERMOPLASTIC POLYMER MATERIAL
A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.
Methods of joining textiles and other elements incorporating a thermoplastic polymer material
A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.
DUCT WITH SHAPE MEMORY MATERIAL, AND INSTALLATION METHOD
Ducting and/or duct couplings can be formed from shape memory polymer material, with the material for example being additively manufactured. The use of shape memory polymer material for one or more of the duct portions may allow for easier installation of the ducting, for example allowing the ducting to be warped and/or bent to fit into or through places that are hard to reach or hard to maneuver through, with the ducting then heated to cause it to return to a predetermined memory shape. The coupling of duct portions together may be accomplished by the duct portions including a shape memory polymer material, with for example ends of the duct portions fitted together, and then heated to use a shape memory property of the material to effect coupling. Heating of the shape memory polymer material also softens the material, allowing it to move to a previously set shape.
VEHICLE LAMP
In a vehicle lamp of the present disclosure, a lamp body is made of an acrylonitrile styrene acrylate (ASA) resin, which has a glass transition temperature lower than that of a poly(methyl methacrylate) PMMA resin constituting a light transmissive cover. That is, with respect to the glass transition temperature Tg1 of the PMMA resin constituting the light transmissive cover, the glass transition temperature of the ASA resin constituting the lamp body is set to Tg1>Tg2. Thus, it is possible to generate not a tensile residual stress but a compressive residual stress in a welding portion between the lamp body and the light transmissive cover, thereby enhancing the solvent resistance of the light transmissive cover. And, thus, an annealing process after the welding is unnecessary, or simply performed.

KNITTED AND WOVEN COMPONENTS AND ARTICLES OF FOOTWEAR CONTAINING THE SAME
A knitted or woven component including an upper of an article of footwear, the upper including a knitted textile that is knitted together via a plurality of yarn such that the plurality of knitted yarn at least partially forms the knitted component. The article of footwear includes a midsole coupled to the knitted textile of the upper such that the midsole is positioned adjacent to the plurality of knitted yarn that at least partially forms the knitted component of the article of footwear, and an outsole coupled to the midsole on an opposite side of the knitted textile of the upper such that the outsole is separated from the plurality of knitted yarn that at least partially forms the knitted component of the article of footwear by the midsole disposed therebetween.
KNIT TEXTILE COMPONENTS WITH FUSED AREAS ON SHOES AND ARTICLES OF FOOTWEAR CONTAINING THE SAME
A knit textile that includes a plurality of yarn that is knitted together to form the knit textile, and the knit textile defines an upper of an article of footwear. A pair of fused regions are formed along the upper, and the plurality of yarn knitted together to form the knit textile is fused to a predefined extent at the pair of fused regions. The article of footwear includes a midsole coupled to the knit textile of the upper such that the midsole is positioned adjacent to the pair of fused regions, and an outsole coupled to the midsole on an opposite side of the knit textile such that the outsole is separated from the pair of fused regions by the midsole.
