Definitions
- Electrically conductive, elastic compound thread in particular for RFID textile labels, and its use and the production of a woven, knitted or braided fabric therewith
- the invention relates to an electrically conductive, elastic compound thread, in particular an antenna thread for RFID textile labels.
- a compound thread is to be understood here as meaning a thread which is composed of different thread elements or fibers.
- the invention relates Polg its use and the production of a fabric, knitted or braided with it.
- a conductor thread which serves as an antenna for a transponder in a label.
- a conductor consists for example of copper and is incorporated by weaving during the manufacture of the textile material or subsequently applied by embroidery technique on a textile. If now the conductor thread itself should be designed to be elastic, then the known conductor threads are not suitable, since in particular the elasticity of the metal thread is not sufficient to maintain the elasticity of the entire thread.
- an electrically conductive yarn is disclosed, with an elastic core thread and - at least - a wound around the core thread, electrically conductive thread and - At least - one, wound around the core thread, electrically non-conductive Umwindefaden.
- the extensibility of the entire, electrically conductive yarn is to be limited by the Umwindefaden.
- Essential for the yarn of WO 2004/027 132 Al is that the elastic core thread gives the yarn an elasticity, while the binding thread ensures that the conductor thread can not tear, since the binding thread limits the extensibility of the yarn.
- composite yarn for use in high temperature range discloses a composite yarn and a composite yarn for processing brittle yarns made of ceramic or the like for knitting machines and sewing machines, in which a load-absorbing, flexible core yarn and the brittle yarn are arranged with a flexible twine so that the composite yarn has a higher tensile strength than the brittle yarn in a curved state with a small radius.
- the above-mentioned yarns are all afflicted with the disadvantage that they can not be incorporated into a textile fabric in a trouble-free manner and that the electrical function after incorporation into or on a textile material is also not guaranteed to be secure.
- the object of the invention is to provide an electrically conductive, elastic compound thread, which can be incorporated as trouble-free as possible into a textile material and whose function remains ensured even after incorporation into or on a textile material.
- the object is achieved according to the invention by an electrically conductive, textile-processable compound thread according to claim 1.
- the Buchentlastungsfaden is arranged opposite the conductor thread under higher tensile stress, so that when a strain of the compound initially the strain relief thread is claimed. Furthermore, the strain relief thread is more resilient than the conductor thread.
- the Buchentlastungsfaden should have an elasticity of 3 to 40% - preferably 5 to 12%.
- the composite thread is provided with textile binding threads or woven.
- the Ceientlastungsfaden be arranged in relation to the conductor so that the Ceientlastungsfaden can be stretched to its tear limit, before the conductor thread can tear.
- the conductor thread at the tear limit of Wernersfadens then its tear limit has not yet reached, but there begins to be charged first, or has reached its maximum proportionality limit.
- binding threads - according to claim 5 - set between 15 and 30 times per cm, preferably between 20 and 24 times per cm.
- the textile binding threads are - as set forth in claim 6 - preferably made of natural or synthetic fibers.
- the Ceientlastungsfaden should be understood here either a single thread, possibly consisting of several fibers or a compound of different individual threads.
- the Buchentlastungsfaden can - for advantageous production - consist of thermally shrinkable material.
- the strain relief thread may consist of natural fibers or of synthetic fibers, preferably of polyamide, polyester or aramid (claim 8).
- the conductor can advantageously have a metallic elasticity (claim 9) and of metal or metal alloys, but also of metallically coated, synthetic fibers, preferably made of polyamide, consist (claim 10).
- the conductor is a compound having at least one metallic and at least one metallic coated synthetic thread (claim 11). This is advantageous, in particular, if electrical bridging takes place, at least in sections, between the metallic and the metallic coated synthetic thread (claim 12).
- an electrically conductive, elastic, textile compound thread described above as an antenna for RFID textile labels or - more generally - as a conductor in fabrics, knitted fabrics and braids (claim 14).
- a woven, knitted or braided fabric is advantageously produced in a separate process and finally incorporated into a woven fabric, knitted fabric or braid.
- FIG. 1 shows a knitted, electrically conductive, elastic compound thread according to a first embodiment of the present invention
- FIG. 2 shows a woven, electrically conductive, elastic compound thread according to a second exemplary embodiment of the present invention
- 3 shows a compound thread with tear resistance diagram.
- FIG. 1 shows a compound yarn 2 according to a first embodiment of the present invention, in which a loose lying conductive thread 4 and a stretched compared to the latter arranged Wegendlastungsfa- 6 forfeited with a binder thread 8 with each other.
- the conductor thread 4 and the strain relief thread 6 are here laid so that the conductor thread 4 is only then subjected to tension at point a + b, when the strain relief thread 6 has already reached its tear limit 62 - at about 28% elongation.
- the tensile strength of the strain relief thread 6 is also greater than that of the conductor thread 4. This corresponds to the case II of the tensile strength diagram of Figure 3.
- This compound thread 2 is produced on a knitting or raschel machine.
- the compound thread has about 22 stitches per cm in this embodiment.
- the strain relief thread 6 is made of synthetic fibers - here made of polyamide - and has a tensile strength 62 of about 28% based on its Stretching on.
- the conductive thread 4 is made of metal, in this case of a silver / copper alloy, but may alternatively consist of metallically coated fibers, here of polyamide.
- a conductor thread 4 made of a metallic thread and a metallic coated thread made of polyamide fibers then takes place at least in places, an electrical bridge formation between the metal thread and the metallic coated thread of polyamide fibers by the geometric arrangement. As a result, a higher conductivity of the metal filament can be linked to a breaking strength, which combines the advantages of a metallic filament and a metallic coated filament.
- the compound thread 22 is produced on a weaving machine.
- the conductor thread 4 is interwoven as a weft thread with the binding thread 8 and the stretched Switzerlandendlastungsfaden 6 held stretched.
- all other features and alternatives of the above-described knitted compound thread 2 also apply to the woven compound thread 22.
- FIG. 3 shows in Case II the example of a tear resistance diagram of a compound thread 2 with two conductor threads 4. It can be seen that the tear strength 62 and the elasticity 60 of the strain relief thread 6, which in this case consists of Trevira 55 dtex, is substantially greater than the tensile strength 42 and the elasticity 40 of the conductor 4, which consists of an AgCU wire.
- the strain relief yarn 6 reaches its proportionality limit 60 at about 5% elongation and its tear limit 62 at about 28% elongation at a tensile strength of up to 10 Newton.
