To provide a fabric heater that can be stretchable in all direction and warms up quickly. The aforementioned problem is solved by means of a fabric heater (1) that comprises a piece of fabric (2) that is formed into one piece by twist-braiding the plurality of loop portions (5) with each other, the plurality of loops portions (5) being formed by conductive thread (4), and electrodes (30) that are comprised by electrode thread (31, 35) and by spacing from each other, and the conductive thread (4) has a core (10) formed by a fiber and a conductive layer (11) or a conductive foil (12) that covers the surface of the core (10) or; by means of fabric heater (1) which is formed by the conductive thread (4) comprises a bunch of lines(7) having at least one or more conductive lines(6a).
摘要:
A heater mat for a rotor blade includes a plurality of electrically conductive heater wires extending in a path along a span of the rotor blade and a plurality of yarn thread knitted to the plurality of heater wires, each of the yarn threads looping around at least one of the plurality of heater wires. A warp thread is positioned between adjacent heater wires and knitted to adjacent pairs of the yarn threads without looping around the plurality of heater wires, to maintain spacing between adjacent heater wires of the plurality of heater wires. An electrical current flowed through the plurality of heater wires inhibits ice accumulation on the rotor blade assembly.

Die vorliegende Erfindung betrifft ein Abstandsgewirk oder -gestrick (10) für Heizzwecke, ein Verfahren zu seiner Herstellung und die Verwendung desselben. Im Stand der Technik sind solche Gewirke in unterschiedlichen Ausführungsformen bekannt, so z.B. in der DE-U1-201 00 915 und EP 1 699 266 B1 . Der Erfindung liegt die Aufgabe zugrunde, ein kostengünstig herstellbares Abstandsgewirk oder -gestrick (10) zu schaffen, das möglichst gute Belastungseigenschaften aufweist und wenig anfällig ist. Diese Aufgabe wird bei dem Abstandsgestrick oder -gewirk dadurch gelöst, dass die Heizdrähte (12) als Schuss-/Einfegefäden ausschließlich in die Zwischenlage (15) beim Stricken- oder Wirken gestreckt eingelegt werden. Von erfindungsgemäßer Bedeutung sind ebenfalls ein Herstellungsverfahren und der Verwendungszweck als heizbarer Bezug für Kraftfahrzeug- oder Flugzeugsitze ( Fig. 1 ).
摘要:
L'invention concerne un dispositif et un procédé pour le soudage de deux pièces en polymères par fusion. La fusion est obtenue moyennant une nappe chauffante (1) tricotée à partir d'un fil résistif revêtu d'un vernis isolant, la nappe chauffante (1) étant conformée pour être alimentée électriquement par un automate réglable en tension ou en intensité de courant et résistant aux courts-circuits. La nappe chauffante (1) est obtenue à partir d'un fil résistif ayant un diamètre allant de 0,2 mm à 0,3 mm, et présente des mailles (M) approximativement parallélépipédiques dont les dimensions (a, b) vont de 1,5 x 3 mm 2 à 2,5 x 4,5 mm 2 .
摘要:
A fabric article that generates heat upon application of electrical power is formed, for example, by knitting or weaving, to form a fabric prebody. An electrical resistance heating element in the form of a conductive yam is incorporated into the fabric prebody, e.g., laid in, e.g., in the knit-welt or tuck-welt configuration, the electrical resistance heating elements extending between opposite edge regions of the fabric. Conductive elements are provided for connecting the electrical resistance heating elements to a source of electrical power.
摘要:
A fabric article that generates heat upon application of electrical power is formed, for example, by joining stitch and loop yarns to form a fabric prebody, with the loop yarn forming in loops that overlay the stitch yarn at the technical face and back (14) of the fabric prebody. An electrical resistance heating element (18) in the form of a conductive yarn is incorporated into the fabric prebody at symmetrical and/or asymmetrical spaced-apart intervals as the stitch yarn, the electrical resistance heating elements extending between opposite edge regions (20,21) of the fabric. The technical face and/or the technical back of the fabric body is finished, in a manner avoiding damage to electrical conductivity of the electrical resistance heating elements, to form a fleece surface region, and conductive elements (40) are provided for connecting the electrical resistance heating elements to a source of electrical power (52). Preferably, the conductive yarn has a core of insulating material, an electrical resistance-heating element about the core, and a sheath material surrounding the electrical resistance heating element and core.
