Abstract

A camouflage net is provided with a base material in the form of a formed-loop knit of polyester fiber, having fractions of metal and plastic in fiber or pigment form and with a camouflage color coating. The polyester formed-loop knit incorporates metal-sheathed polyamide fibers and optionally polyamide fibers comprising electroconductive pigments.

Description

C~sxgla~e ri6'~
This inwentzon relates to a camouflage net ha~ra.ng a base material in the form of a formedrloop knit of polyester fiber, having fxactians of metal end plastic in fiber or pigment form and having a camouflage color.
coating.
A camouflage net of ~,he kind descr_ i.bed is known~ for example from EP 0 468 1?3 B1. It consists of a, polyes~
ter fiber base material in the form of a J.oop-formingly knitted' material into which.meLal fibers are inlaid.-Above the poJ.yester fiber knit containing metal fibers is disposed a polyurethane polymer layer which contains carbon absorber pigments. The polymer layer is rendered flame retardant anal additionally coated with an infra-red camouflage color>
The previously known camouflage net is effect'l~re not only against.detection in radar and thermal imaging but also against detection in the ~lea.r i.nf..r.ared region.
It is an object of the present invention. to further im-prove a. camouflage net of the kind descxibPd,, espc-ci.ally with regard to its effectiveness ax7d its han-dling in use.
This object is achieved according to the invention when the polyester formed-loop. knit incorporates metal-sheathed polyamide fibers.
The use of metal-sheathed or metalizc>d polyamide in-stead of the previous metal fibers providES larger sux--face areas while reta~.ning a percentage basis we~.ght of the incorporated metal and hence also a larger reflec-t~_ve area. The metalized polyamide fibers incorporated in the polyester formed-loop knit provide a distinctly improved result in relation. to radar absorption and scattering, ie a superior directional independence.
The incorporation of metalized polyamzde, preferabJ.y disposed randomly or in 'various directions i.n the formed-loop knit, distinctly impro~res the radar at tenuation values. The metalized polyamide fibers, wh~.Ch are responsible ,far any reflection; provide a dis ti.nctly superior scattering effect than the previously known metal fibers, which were predominantly oxiented in. one direction.
In a very advantageous xefinemcnt o~ the invention, the formed-laop knit znay additionally incorporate polyami.de fibers comprising electroconductive pigments or fibexs to achieve the requishe absorption of .radar beams.
This measure saves one layer~ namely the polymer layer, compared with the known camouflage net:, The many-layered construction and the many-layered add-on plies in the case of the known camouflage net could lead to varying dependencies in relation to the empJ.oyment of the binder quantity required therefor and the flame re-.
tardant system; and this was in some instances a disad-'~~t~~~~~ i~~r ~h~ ~affec~i~~nesa of the camouflage net.
Moreover, dispensing with the polymer layer makes the camouflage net as a whole lighter and easier to handle as a result. This means at the same time that the cam-ouflage net of this invention already possesses basic attenuation for IR reflection and thus that the paint=

-7.ng colors for a camouflage layer and for f~:ame retd~~°
dancy require a reduced fraction of carbon and hence bp.nder quantities. In addition, the camouflage net of th3_s invention also becomes more flexible as a result.
In a further advantageous devel~apment of this inven-tion, the formed-loop knit composite additionally in-ccrporates a horizontal inlay comprising polyester fi-bers and polyamide fibers which are metal sheathed and/or provided with e.lectroconductive pic~m~nts or fi-bers.
This measure of this invention provides even supera.or effectiveness and utility to the camouflage net.
Advantageous refinements and further deve7.opm.ents will be apparent from the remaining subclaims and from. the exemplary embodiment illustrated in principle below with referenCC to the drawing, in which:
rig. 1 shows an enlarged outline representation of the camouflage net according to this invention;
Fig. .2 shows a dota,il of a polyester fa.,ber with poly-~5 amide fibers iri a am~ch eailarged representation;
Fig. 3 shows a.n enlarged detail as per TIT from F3g. 2; and Fig. 1 shows, a.n outline representation, a base matd--rial which is a farmed-loop kna.t of polyester fibers 1 which has been constructed in known manner :from pillar and inlay. The inl.ay~ as well as the polyester fibers 1., includes metal-sheathed polyamide fibers 2a and po-lyamide fibers 2b having elect.roconductive pigments 3 on the surface of the polyamide fibers. The: metaliza-tion of the polyamide .fi.bers 2a is aCCOmplished by pro-viding a coat or sheath of conductive metal 4 over the polyamzde fibers 2a, for iahich the metal may be applied by electroplating. An example of a useful metal is sil-ver with or without alumintam. As is evident fram Fig. 3, the polyamide fibers 2a and 2b may have a round cross section . 7~7.ternativcly, they rnay also have a tri--labal cross-sectional shape ora cross-sectional shape in the manner of a three-leaf clover.
The polyarnidc fibers 2a and 2b with them metal sheath-ing 4 or with their pigments 3 are ~.ncorporated into the formed-loop knit random:Ly or in z~.gzag shape. The pillax stitches of the formed-1~op knit arm gcnera~.ly iorrned f..rom polyester fibers 2 onlya The polyamide fibers 2a and 2b, which axe distinctly thinner in crass section than the polyester fibers 1, can be 6,6 monofilamcnts. The layer l:h.ickness of the polyamide fibers 2a and 2b can be between 0.5 anc~ 2.0 ~
end preferable ~.s 1.0 ~.
Tire conductiv~,ty of the electroconductive po7.yamide fi-hers 2b with their carbon pigments ~ can preferably be between 3XI0~ to 35x10 S2/cm.

.. -The linear density of the polyamid~ fibe,r,s 2a and 2b can preferably be from 0.13 denier to. 0. ~~i denier.
'fhe weight fraction of the polyamide fibexs 2a and 2b in the formed-loop knit compos~ae can be for example in the range from 3~ to 15a.
It w~,Il be appreciated that other values and fractions are also possible withJ.n the.scope of the in~rention.
In addition, the formed-ioop knit ~na.y incarporate an inserted weft 6 composed of polyester fibers. Here too the polyester fibers 1 can be twisted with polyaml.de fibers 2a, wh~.oh are sheathed with metal 4; and/or with Z5 polyamide fibers 2b, which are provided with carbon pigments 3.
The formed-loop kr~a,t composite of polyester fibers 1 'and polyamide fibexs 2a and 2b is bothsidedly provided 20 with a flame-retardant coating 7 in known manner in such a way that the polyester fibers 1 and the polyam-ide fibers 2a and 2b are encased by. the fl~m~ retardant on virtually all sides. Tn addition, a camouflage color print 8 can be applied to at least one side'o:C the for-25 med-loop kna.t. The manner of the camouf7.age color print 8' depends on the nature of. the terrain for which the camouflage net is i;o be used. In open terrain, the ca-moutlage colors used will usual~.y be mottled grccn/brown in surnmcr arid a white ground color in win-30 ter. If desired, .the camouflage net can also be printed with different camouflage coJ_ors on each side, for dif-ferent deployments.
