Description
[0001] The present invention relates to a method of providing a
tubular protective sleeve and a sleeve.
BACKGROUND OF THE INVENTION
[0002] Known are in the art the tubular protective sleeves, made of
a warp knitted fabric with filaments of three different components
the first component comprising monofilaments and/or multifilaments
of a first polymer, the third component comprising an electrical
conductive material.
[0003] In the European Patent Application 11382361, form the same
applicant, a sleeve with these features is disclosed.
[0004] However, it is a conductive wire between surfaces and if it
is desired this cable to be isolating, it is necessary to add
another insulating sleeve, with the cost, volume, and additional
weight it involves.
DESCRIPTION OF THE INVENTION
[0005] To this end, the present invention proposes a method for the
manufacture of tubular protective sleeves, comprising the steps of:
[0006] providing a warp knitted fabric made of three filaments
components using a Raschel type loom; and [0007] shaping the tissue
so that the longitudinal edges of the tissue converge towards one
another and overlap with each other, thus defining a tubular shape;
[0008] the first component comprising monofilaments and/or
multifilaments of a first polymer; [0009] the third component
comprising an electrical conductive material; [0010] said
components being distributed throughout the thickness of the tissue
such that: [0011] the first polymer component is present throughout
the thickness; [0012] the second component has a symmetrical or
asymmetrical distribution throughout the thickness in respect to a
median plane of the tissue; [0013] the third component extends from
one side of the tissue to the interior of the tissue without
reaching the opposite side; [0014] the minimum weight percentages
being as follows: [0015] 7% for the first component; [0016] 10% for
the second component; [0017] 40% for the third component;
[0018] With these features, an insulating sleeve of reduced weight
and volume is obtained, which serves as shielding and which is
electrically conductive in the longitudinal direction. Notably, the
conductive portion may remain on one the sides or inside.
[0019] The first component groups and binds the other components,
the second has insulating functions, and the third conducts
electricity.
[0020] According to various optional features, in the process of
the invention: [0021] either the components are different, or
either the first and second components are made of the same
material. [0022] the second component are multifilaments of a
second polymer. [0023] the first polymer is selected among
polyphenylene sulfide, polyester, polyamide, PEEK, PTFE, ECTFE and
PFA. [0024] the second polymer is selected among polyester,
polyamide, pps, PEEK, Meta-aramid, Para-aramid, Viscose, PTFE,
ECTFE and PFA. [0025] the electrical conductive material is
selected among copper, tinned copper, nickel copper, aluminum and
stainless steel. [0026] the strips of the edges having a
longitudinal direction does not comprise third component.
[0027] The invention also relates to a tubular protective sleeve,
composed of a warp knitted fabric with filaments of three different
components, [0028] the first component comprising monofilaments
and/or multifilaments of a first polymer; [0029] the third
component comprising an electrical conductive material; which is
characterized in that the first, second and third components are
distributed throughout the thickness of the tissue such that:
[0030] the first polymer component is present throughout the
thickness; [0031] the second component has a symmetrical or
asymmetrical distribution throughout the thickness in respect to a
median plane of the tissue; [0032] the third component extends from
one side of the tissue to the interior of the tissue without
reaching the opposite side; [0033] the minimum weight percentages
being as follows: [0034] 7% for the first component; [0035] 10% for
the second component; [0036] 40% for the third component;
[0037] According to various optional features, in the inventive
sleeve: [0038] the components are different or wherein the first
and second components are made of the same material. [0039] the
second component are multifilaments of a second polymer. [0040] the
first polymer is selected among polyphenylene sulfide, polyester,
polyamide, PEEK, PTFE, ECTFE and PFA. [0041] the second polymer is
selected among polyester, polyamide, pps, PEEK, Meta-aramid,
Para-aramid, Viscose, PTFE, ECTFE and PFA. [0042] the electrical
conductive material is selected among copper, tinned copper, nickel
copper, aluminum and stainless steel. [0043] the strips of the
edges having a longitudinal direction does not comprise third
component.
