Improvement in the multilayer material and process for the manufacture of multilayer material

摘要

"Improvement in material and process for manufacturing multilayer multilayer material. The present invention relates to an improvement in the material suitable for use as a multilayer structure of reinforcement in the manufacture of footwear.The material multiface sandwich type has an intermediate layer (b) consisting of a mixture of thermoplastic resins with loads of vegetable fibres and fibres; on which is laminated a stingy of nonwoven blanket 100% polyester fibres impregnated with an emulsion based D Water (synthetic latex) combined with natural and inorganic loads; and coated with an adhesive layer of the tipThe hot set and / or resins olefu00ednicas, on the cloth impregnated with (a). The improvement consists of a mechanical process of chanfrau00e7u00e3o, said chamfer (lower layer of the peripheral margins) and may be in its upper side and / or less. This training aims to provide more comfort, giving more flexibility to the heel of the user.
