摘要:
L'invention concerne un élément de garnissage (1) de véhicule comprenant : - un complexe (6) comprenant au moins une couche de matériau ligneux (10) ayant une face extérieure et une face intérieure, et une couche de renfort (8), s'étendant sur la face intérieure de la couche de matériau ligneux (10) ; et - un support (2) réalisé dans une première matière plastique. L'élément de garnissage (1) comprend en outre au moins un insert (4), réalisé dans une deuxième matière plastique, interposé entre la couche de renfort (8) du complexe (6) et le support (2) de manière à espacer le support (2) de la couche de renfort (8), le support (2) étant surmoulé par injection sur l'insert (4).
摘要:
The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology. The present invention more specifically discloses a hose which is comprised of (1) an elastomeric tubular inner core layer (12) defining a lumen, (2) a friction layer (14), and (3) an elastomeric cover (30), wherein the elastomeric tubular inner core layer (12) is comprised of (i) a chlorinated elastomer selected from the group consisting of epichlorohydrin, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, (ii) 1 phr to 50 phr of a chlorinated paraffin, and (iii) 30 phr to 120 phr of carbon black. It is typically preferred for the chlorinated elastomer to be chlorinated polyethylene or chlorosulfonated polyethylene.

An article of footwear (10) may have a sole structure (20) and an upper (30) that includes at least one layer (43, 44) and a plurality of strands (41, 42). The layer extends from a lace region of the upper to a lower region of the upper. The strands are located adjacent to the layer and in contact with the layer, and the strands extend from the lace region to the lower region. Additionally, the strands are unsecured to the layer for a distance of at least five centimeters in an area between the lace region and the lower region.
摘要:
The invention relates to a laminate and method for continuously producing a flexible, liquid-absorbent laminate having two outer material webs, of which at least one is formed from a textile material, between which are inserted at least two stretchable-elastic intermediate layers that are pre-stressed with respect to said layers and comprise threads or bands running in opposite directions to each other and at an angle to the production direction. The intermediate layers shorten and gather the web material substantially transversely to the production direction thereof when the intermediate layers are relieved of stress. Powdery or fiber-shaped inclusions, which have absorbent properties for liquids, such as urine, blood, water, or sweat, or resorbing properties, such as the release of medicinal substances, cosmetic ingredients, or the generation of heat/cold, are introduced into the free spaces of the elastic intermediate layer.

The invention relates to a method for the continuous production of a flexible liquid-absorbing web material having two outer layers, at least one of which is formed by a textile material, between which are inserted at least two stretchable-elastic intermediate layers that are pre-stressed with respect to said layers and comprise filaments or bands arranged running in opposite directions to each other and obliquely with respect to the production direction. The intermediate layers shorten and gather the web material substantially transversely to the production direction thereof when the intermediate layers are relieved of stress. Powder-form or fibre-form inserts, which have absorbent properties for liquids, such as urine, blood, water or sweat, or resorbing properties, such as release of medicinal substances, cosmetic ingredients or for generating heat/cold, are introduced into the free spaces of the elastic intermediate layer.

The present invention relates to the field of composite structures, overmolded composites structures and processes for their preparation, particularly it relates to the field of polyamide composite structures. The disclosed composite structures have a surface, which surface has at least a portion made of a surface polyamide resin composition, and comprise a fibrous material selected from non-woven structures, textiles, fibrous battings and combinations thereof, said fibrous material being impregnated with a matrix resin composition, wherein the surface polyamide resin composition is selected from polyamide compositions comprising a blend of a) one or more semi-aromatic polyamides (A) containing repeat units derived from aromatic dicarboxylic acids and aliphatic diamines, and b)one or more fully aliphatic polyamides (B) selected from the group consisting of polyamides containing repeat units derived from aliphatic dicarboxylic acids and aliphatic diamines, polyamides containing repeat units derived from aliphatic aminocarboxylic acids, and polyamides derived from lactams.
