Method of producing a fibrous product and a fibrous product
The present invention relates to multi-layer fiber products and a method of manufacturing these kinds of products. The present product comprises a first layer consists mainly of natural fibers and a second, heat-sealing layer located on top of the first layer. The heat-sealing layer consists mainly of synthetic thermoplastic fibers or particles. According to the present method, the heat-sealing layer is brought onto the first layer already during the web forming process, the first and the second layers being formed and joined together in a foam forming process. With the present invention, it is possible to decrease the amount of plastic materials in packaging materials having heat-sealing properties.
Composite pressure vessel with a monolayer liner
A composite pressure vessel that includes a monolayer liner and a reinforcing structure arranged on top of the liner. The liner is made by injection moulding and includes at least two shells weldable together. Each shell is made of a polymer composition including at least 45% by weight of an aromatic polyamide relative to the total weight of the polymer composition, and at least 10% by weight of an aliphatic polyamide relative to the total weight of the polymer composition.
Multilayer film including foam layer and ostomy products made therefrom
An ostomy appliance includes a multilayer composite film comprising at least one foam layer. An outer foam layer can function as a skin contact layer providing comfort and softness characteristics that are comparable to a nonwoven comfort layer. Preferably, at least one foam layer includes a vinyl-bond rich triblock copolymer and provides sound absorbing properties. The multilayer composite film can also include at least one layer comprising a filler to further enhance sound absorbing properties.
Two-component polyurethane adhesive for lamination
1) Two-component polyurethane-based adhesive composition comprising an —NCO component and an —OH component, such that: the —NCO component is obtained by polyaddition between MDI and a composition of polyols comprising a polyether diol and a polyether triol, in an —NCO/—OH molar equivalent ratio of between 2.5 and 6.5; the —OH component is obtained by polyaddition between MDI and a composition of polyols with a functionality of 2 comprising an aliphatic polyester diol, a partially aromatic polyester diol and an aliphatic polyether diol, in an —NCO/—OH molar equivalent ratio of between 0.05 0.50; the amounts of the —NCO and —OH components being such that the —NCO/—OH molar equivalent ratio is within a range extending from 1.5 to 1.7. 2) Multilayer film comprising 2 thin layers of material linked to one another by a continuous layer constituted by said crosslinked adhesive composition. 3) Process for preparing said film and use thereof in the manufacture of flexible packagings.
OUTER PACKAGE MATERIAL FOR ALL-SOLID-STATE BATTERIES, METHOD FOR PRODUCING SAME AND ALL-SOLID-STATE BATTERY
An outer package material for all-solid-state batteries, which is composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer and a thermally fusible resin layer in this order, and which is configured such that the multilayer body has a layer that has a buffering function on the outer side of the thermally fusible resin layer.
Barrier structure based on MPMDT/XT copolyamide with a high Tg
A barrier structure for the storage and/or transport of fluids, including at least one barrier layer (1) including an MPMDT/XT copolyamide in which: MPMDT is a unit with an amide motif having a molar ratio of between 5 and 50%, particularly between 5 and 45%, preferably between 15 and 45%, more preferably between 20 and 45%, where MPMD is 2-methyl pentamethylene diamine (MPMD) and T is terephthalic acid, XT being a unit with a majority amide motif having a molar ratio of between 50 and 95%, particularly between 55 and 95%, preferably between 55 and 85%, more preferably between 55 and 80%, where X is a C9 to C18, preferably C9, C10, C11 and C12, linear aliphatic diamine, and where T is terephthalic acid, the copolyamide having a melting point of 250° C.<T.sub.f≤300° C. as determined according to the ISO norm 1 1357-3 (2013).
Polyolefin based films with matte surface and improved sealing performance
Embodiments of the present disclosure are directed to multilayer films, which provide matte appearance and low heat seal initiation temperature after corona treatment. The multilayer films include at least one matte layer comprising ethylene-based polymer and propylene-ethylene copolymer.
Composite sidewall and cargo body having same
A composite molded cargo body panel including a core, an interior skin secured to a first side of the core having a thickness, and exterior skin secured to a second side of the core, and a plurality of recesses. The plurality of recesses are dispersed along a first direction at intervals in the interior skin, with the core thickness at each of the plurality of recesses being reduced compared to a maximum core thickness, and each of the plurality of recesses defines a support surface. A pocket is formed in each of the plurality of recesses, with the core thickness at the pocket being less than the core thickness at each of the plurality of recesses. A plurality of logistics inserts are attached to the respective support surfaces of the plurality of recesses so that, at each of the plurality of recesses, the logistics insert extends across the pocket.
Repulpable container insulation products and methods of making and using same
Container insulation including a batt comprised of large paper particles, at least 90% of which by weight are greater than 10 mm in diameter. Less than 5% by weight binder fibers are used, which have a length of at least 20 mm. Most preferably, no binder fibers are used. Where the batts are faced with paper, the paper is coated with a biodegradable coating. The resulting product is repulpable and recyclable in accordance with Fiber Box Association (FBA) testing protocols.
Thermoplastic composite in-situ melt processing method for composite overwrapped tools
An in-situ melt processing method for forming a fiber thermoplastic resin composite overwrapped workpiece, such as a composite overwrapped pressure vessel. Carbon fiber, or other types of fiber, are combined with a thermoplastic resin system. The selected fiber tow and the resin are prepared for impregnation of the tow by the resin. The resin is melted; and, carbon fiber is impregnated with the melted resin at the filament winding machine delivery head. The molten state of the composite is maintained and is applied, in the molten state, to the heated surface of a workpiece. The portion of the surface being wrapped is heated to the melting point of the thermoplastic resin so that the molten composite more efficiently adheres to the heated surface of the workpiece and so that the uppermost layer of fiber resin composite is molten when overwrapped resulting in better adherence of successive layers to one another.
