Tubular protective sleeve

A method for the manufacture of tubular protective sleeves, comprising the steps of:

• providing a warp knitted tissue made of filaments of three components using a Raschel type loom;
• and
• shaping the tissue so that the longitudinal edges of the tissue converge towards one another and overlap, thus defining a tubular shape;
• wherein a first component of said three components comprises monofilaments and/or multifilaments of a first polymer;
• wherein a third component of said three components comprises an electrically conductive material;
• wherein said three components are distributed throughout a thickness of the tissue such that:
• the first component is present throughout the thickness;
• a second component of said three components has a symmetrical or asymmetrical distribution throughout the thickness in respect to a median plane of the tissue;
• the third component extends from one side of the tissue to the interior of the tissue without reaching the opposite side;
• and
• wherein the minimum weight percentages of each of the three components is as follows:
• 7% for the first component;
• 10% for the second component;
• 40% for the third component.
