Method for producing an elastic protective material, especially intended for a medical safety glove. The material comprises at least two parts. A core layer (1) is produced by knitting yarn made of high-tenacity polymer fibres; this layer serves to prevent penetration of the glove by a sharp object. The core layer (1) is entirely surrounded by one or several polymer layers (2), which serve to prevent gas or liquid from penetrating the glove. The material is characterized in that, particularly to optimize the sensibility and safety, at least one knitted layer (1') belonging to the core layer (1) is produced to a knitted structure using a machine gauge of at least 10 needles per English inch.

Cette invention concerne un procédé de production d'une matière élastique protectrice, destinée particulièrement à un gant de protection pour chirurgien. Ladite matière est constituée d'au moins deux parties. On fabrique une couche de base (1) en tricotant du fil fait de fibres polymères haute-ténacité, ladite couche servant à éviter la pénétration du gant par un objet pointu. On entoure entièrement ladite couche de base (1) par une ou plusieurs couches polymères (2) qui permettent d'éviter la pénétration de liquide ou de gaz à l'intérieur du gant. Ladite matière se caractérise en ce que, afin d'optimiser particulièrement la sensibilité et la sécurité, on élabore au moins une couche tricotée (1') qui fait partie de la couche de base (1) jusqu'à l'obtention d'une structure à mailles au moyen d'une jauge de métier d'au moins 10 aiguilles par pouce anglais.
