摘要:
Elastomeric films and laminates comprising one or more biodegradable and/or sustainable polymers are disclosed. The biodegradable and/or sustainable polymers can be added to the elastomeric film at concentrations up to about 40%, while the film still retains acceptable elastomeric properties. Methods of making elastomeric films or laminates comprising one or more biodegradable and/or sustainable polymers are also disclosed.

A film that is formed from a thermoplastic composition is provided. The thermoplastic composition contains a rigid renewable polyester and a polymeric toughening additive. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase tensile elongation. To even further increase the ability of the film to dissipate energy in this manner, the present inventors have discovered that an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus reduces the stiffness (tensile modulus) of the film.

The present invention relates to a composite article and to a process for manufacturing the composite article. The composite article comprises multiple layers including high tenacity fibers incorporated into a fabric and a core thermoplastic resin. The fabric may be coated with a surface treatment agent, a polymer matrix resin. Single or multiple layers of the composite articles may be formed into a composite part having high strength, rigidity, fast molding cycle time and extremely good conformability in a 3- dimensional mold. The composite parts formed by this process have high part strength in all directions.

A sole (1) for a pedestrian's shoe or a slipover device (18) for such a shoe has a base consisting of a non-woven microfibre material made of thermoplastic polyester or polyamide. The microfibre material is exposed in an arcuate section (5) in the f ront foot portion (2), in the mid-foot portion (3) and in a wheel-shaped section (6) in the heel portion (4) of the sole. An elastomer material is deposited as rounded knobs onto the microfibre material in a fore portion (7) of the front foot portion (2) and in a ring (8) and sectors (9) in the heel portion (4) of the sole (1). A PVC material is deposited, also in the form of rounded knobs, in a transverse band (10) in the front foot portion (2) and in a larger part (11) of the heel portion (4) so as to surround the ring (8). The use of the microfibre material as a means of enhancing friction on an icy surface is also disclosed.

This invention concerns an elastic multilayer composite, comprising an elastic film layer sandwiched between a first elastic nonwoven layer and an optional second elastic nonwoven layer, and a process for making the same. The laminate is stabilized via bonding according to either: adhesive bonding between the film and nonwoven layer(s), direct extrusion lamination of the film to one or more nonwoven layer(s), or attachment of the film to one or more of the nonwoven layers at a plurality of points via thermopoint bonding. This invention also concerns a process for manufacturing an elastic multilayer composite, comprising: bonding under neutral tension or substantially neutral tension at least one elastic film layer to at least one elastic nonwoven layer. This invention also concerns a process for manufacturing an elastic multilayer composite, comprising: bonding under differential tension or stretch at least one elastic film layer to at least one elastic nonwoven layer, where either the film or the nonwoven or both are stretched Further the invention relates to a process whereby the elastic nonwoven(s), the film, the composite or any combination is activated, especially stretch activated, to create or enhance elasticity or the touch of the nonwoven, to create pores in the elastic film, or to soften the composite .

The invention relates to multi-layer laminates consisting of at least two thermosetting binding-agent layers and two layers consisting of textiles, said laminates being suitable for reinforcing planar substrates. The inventive multi-layer system contains a binding-agent layer facing the substrate to be reinforced (11), followed by a fibrous-textile layer (13), covered by a second binding-agent layer (14), which is covered in turn by a second fibrous-textile layer (15). Once cured, the binding-agent layer facing the reinforcing substrate forms an adhesive bond with the substrate to be reinforced and has either an identical or lower elasticity modulus than the second binding-agent layer (14) facing away from the substrate. Multi-layer laminates of this type are suitable for reinforcing thin-walled substrates with no read through effect, in particular automobile construction parts with large surface areas, such as doors, roof parts, engine compartment covers, boot lids or similar.
摘要:
A polymeric fibrous base textile with a chemically compatible hot melt coating disposed across the base textile is provided. The coating is present in an amount and is of a composition such that upon application of heat and pressure the coating may be melt bonded to a second surface material thereby establishing a bond between the base textile and the second surface material. In addition, the concentration and composition of the coating are such that scrap portions of the base textile including the coating may be directly reprocessed by shredding and melting to yield a fiber grade material suitable for fiber formation and reprocessing back into a suitable base textile.
