Methods for forming discrete deformations in web materials are disclosed. In some embodiments, the method involves feeding a web into an apparatus having nips that are formed between intermeshing rolls. The apparatus may be in the form of nested or other arrangements of multiple rolls, in which the web is maintained in substantial contact with at least one of the rolls throughout the process, and at least two of the rolls define two or more nips thereon with other rolls. In some embodiments, rolls can be used to expose a different side of the web for a subsequent deformation step. In these or other embodiments, the rolls can be used to transfer the web between rolls in such a manner that it may offset the rolls and/or web so that subsequent deformations are formed at a different cross-machine direction location than prior deformations.

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.

A gas-permeable porous fluororesin membrane (4) made of a fluororesin is welded to a resin component (2) made of a thermoplastic resin using a welding horn (62) having a working surface (62p) adapted to be brought into contact with a work object and provided with a projection (62t). The working surface (62p) of the welding horn (62) is provided with, for example, a plurality of projections (62t). The plurality of projections (62t) may be arranged in a grid pattern on the working surface (62p).

A multi-layer thermoplastic film include a first film of thermoplastic material, a second film of thermoplastic material bonded to the first film, and an odor control component disposed between the first film and the second film. A method of manufacturing a multi-layer thermoplastic film coextruding a plurality of layers to form a first film, coextruding a plurality of layers to form a second film, disposing at least one odor control component on at least one of the first film and the second film, and bonding the first and second films together such that the at least one substance is disposed between the first film and the second film.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

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.

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.

Provided are an elastic composite non-woven fabric and a manufacturing equipment and a manufacturing method thereof, wherein the elastic composite non-woven fabric manufacturing equipment includes an upper feed roller, an upper shrink roller, an upper bonding roller, upper fins, an middle feed roller, an winding roller, a lower feed roller, a lower shrink roller, a lower bonding roller, and lower fins. Wherein, two elastic non-woven fabrics shrink inward by the shrink roller and enter the gaps among the fins and grooves and teeth of the bonding roller to form regular wavy folds; the two pre-shrunk elastic non-woven fabrics are bonded to the upper and lower surfaces of the elastic material in a flat state by the aligned and adjacently disposed teeth of the bonding roller, thereby forming an elastic composite non-woven fabric.
