摘要:
A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.

A laminate (10) comprising a microporous thermoplastic polymer layer (12) such as a microporous polypropylene layer and one or more fabric layers (16) is provided. The laminate (10) is both waterproof and breathable. The laminate (10) is also durable and can be made at low cost. The fabric (16) can be a woven fabric or a knit fabric. Alternatively, a non woven fabric can be used to make a disposable article. The laminate (10) can be used in garments for sports wear, protective clothing or medical uniforms.

L'invention concerne un complexe textile (1) destiné à être intégré dans la structure d'Une pièce moulée réalisée par infusion de résine. Ce complexe associe : • au moins une couche d'une structure textile de renfort (2) ; • au moins une couche drainante (3) formée d'une structure ajourée, apte à former une zone de passage préférentiel de la résine lors de l'infusion. Cette couche drainante demeure dans la pièce moulée après infusion. Ces couches de renfort (2) et de drainage (3) sont mécaniquement solidaires par l'intermédiaire d'un interface de collage (5), de sorte que le complexe reste déformable.
摘要:
A polymer film is laminated to a metal sheet or strip. In one and the same line and in sequence, an adhesive is applied as a dry electrostatic powder, the powder is heated so that it melts and the film is calendered to the metal. The metal sheet or strip has a conversion coating that contains an organic component. The conversion coating is applied as a water solution that is dried to leave a conversion coating that is preferably thinner than 1 mu m. The organic component in the conversion coating makes the adhesive adhere better to the metal.
