A transversely extensible continuous elastic laminates includes a continuous elastic tape sandwiched between two continuous webs, and at least one row of tabs extending transversely outside the two webs, wherein the tabs are made of a non-woven material and have respective micro-hook formations integrally formed in the non-woven material forming the tabs.

A preparation method of a composite non-woven fabric by pleating to enhance stretchability, includes unwinding an upper layer of non-woven fabric and a stretch film, and adjusting them in position; pleating the adjusted upper layer of non-woven fabric along a cross direction (CD) or machine direction (MD) through an upper pleating mechanism, and aligning the pleated upper layer of non-woven fabric with the stretch film; feeding the upper layer of non-woven fabric and the stretch film aligned with each other into a first laminating device, and laminating a contact surface between the bottom of the pleat and the stretch film to obtain a double-layer stretch non-woven fabric material; and rewinding the laminated stretch material after tension adjustment and alignment. The method produces not only a CD- or MD-stretch material but also a four-way stretch material; by adding a pleated design to the non-woven fabric.

Systems, methods, and devices relating to an additively manufactured multilayered structure. The additively manufactured multilayered structure may be provided by unspooling a material roll of laminate material using a roller system. A welding device may be used to apply welds between layers of the laminate material to distribute a loading between the layers during use.

A method and system for the production of a web the fibers of which form a mean angle with respect to the longitudinal direction. The method and system include the passage of the web through a looping system, the passing of the web over a conveyor provided with brushes, the deposition of a first pre-needle-punched layer of fibers over the accumulated undulations, the assembling of the accumulated undulations with the first pre-needle-punched layer by needling, the assembling of the structure with a second pre-needle-punched layer of fibers, so as to obtain a sandwich structure, and the separation of the sandwich structure so as to obtain two symmetrical velour coverings. The web is a card web with a mean angle between 5 and 10 and an area density between 80 and 120 g/m.sup.2. The method includes a longitudinal drawing of the web, with a stretch ratio between 1.5 and 2.

A multilayer film includes: an inner layer system having a first surface and a second surface; and a first skin layer and a second skin layer bound to the inner layer system at the first and second surfaces respectively. The inner layer system consists of a polymer formulation (A) containing: 60.0 and 90.0 wt % of a linear low-density polyethylene A; and 10.0 and 40.0 wt % of a high-density polyethylene having a density of 940 and 970 kg/m.sup.3; and at least one of the first or the second skin layer(s) is a sealing layer comprising a linear low-density polyethylene B comprising polymeric moieties derived from ethylene and 1-octene/1-hexene, having a density of 890 and 915 kg/m.sup.3. The multilayer film is a bi-directionally oriented film and can produce a sealed package having a high sealing strength and improved tensile properties.

A method of preparing a free-standing film of high aspect ratio molecular structures (HARM-structures) includes arranging a second frame from an opening of a first frame to a position where the second frame is in contact with a film of HARM-structures for stretching the film into a stretched position where the second region of the film is supported by the second frame as the free-standing film. An evaporating wetting agent forms a contact surface between the second frame and the second region of the film. The film is in the stretched position at a moment when the evaporating wetting agent evaporates so that the second region of the film adheres to the second frame. The second region of the film is separated from the first frame.

Disclosed are a three-dimensional botanical leather fabric and a manufacturing method thereof. The three-dimensional botanical leather fabric includes an elastic fabric, an adhesive pattern layer and a botanical leather, the adhesive pattern layer is formed by coating an adhesive glue on a surface of the stretched elastic fabric, and the adhesive pattern layer has multiple spacings; the botanical leather is attached on the adhesive pattern layer and the elastic fabric when elastically restores to original state to drive the spacings to be shrunk, so that the botanical leather is formed with a flat fitting part attached to the adhesive pattern layer and a three-dimensional embossed pattern protruding to the outside with the shrinking of the spacings.

A compound equipment of a latex-free tufted carpet is provided. The compound equipment includes an unwinding device, a compound roller, and a shaping device. The unwinding device is configured to unwind a rolled blank blanket, a hot-melt fiber mesh, and secondary cloth. The compound roller is configured to stack and compound the unwound blank carpet, the unwound hot-melt fiber mesh and the unwound secondary cloth in sequence to obtain a preformed tufted carpet. The shaping device is configured for the setting of the preformed tufted carpet at a preset temperature to obtain a finished tufted carpet. Combined with the hot-melt fiber mesh, the secondary cloth and the blank carpet are consolidated by means of thermally induced bonding, and latex is not needed for consolidation.
