Definitions

  • the present invention relates to a method of producing electrothermal filament and the electrothermal filaments themselves, and more particularly a method of producing electrothermal filament containing carbon black by a grafting technique and the electrothermal filament containing carbon black.
  • cloth Since so many improvements have taken place in the textile field, cloth has to have more features to attract consumers. Multiple features such as waterproofing or heat retention are added to finished cloth. How to make cloth retain heat is a special and valuable feature to textile manufacturers.
  • the present invention has arisen to mitigate and/or obviate the disadvantages of the conventional electrically conductive fiber.
  • the main objective of the present invention is to provide a method of producing electrothermal filament containing carbon black that produces electrically conductive filaments having excellent resilience and durable electrical conductivity even after repeated laundering.
  • a method of producing an electrothermal filament containing carbon black in accordance with the present invention comprising the acts of obtaining the materials, grafting carbon black to monomers to form grafted copolymers, coating a filament with the grafted copolymers, laminating a membrane on the filament and attaching two electrodes to each electrothermal filament.
  • the material that must be obtained to perform the method of producing an electrothermal filament containing carbon black consists of micro-powder carbon black, a grafting monomer, an initiator, a terminating agent, nitrogen gas and rolls of a membrane.
  • Carbon black is micro-particles and is conductive material.
  • the grafting monomer is styrene, and the initiator contains 0.5 ⁇ 2% benzoyl peroxide.
  • the terminating agent is acetone.
  • the membrane is a soft, flexible material such as a polyethylene (PE) or thermoplastic urethane (TPU) elastomer.
  • the carbon black, grafting monomer (styrene) and the initiator (benzoyl peroxide) are mixed in a reaction tank to form a grafted copolymer. Then, nitrogen gas is guided into the reaction tank to maintain the temperature of mixture in the tank at 60°C. The grafting reaction takes 6 ⁇ 8 hours. At the end of the grafting reaction, the terminating agent (acetone) is added to the reaction tank to stop the grafting reaction thereby controlling the quantity of carbon black in the grafted copolymer. Consequently, the quality of the grafted copolymer is controlled and stable.
  • the grafting reaction is depicted in the following chemical reaction: Carbon black + C 6 H 5 -(C 2 H 2 ) 60°C for 6 ⁇ 8hr carbon black-(C 2 H 2 )-C 6 H 5
  • the carbon black is grafted with monomer by free radicals of the carbon black to coat a layer of monomer around outer periphery of the carbon black micro-particles.
  • each carbon black micro-particle repulse others to avoid coagulation between carbon black micro-particles.
  • filaments are passed through the grafted copolymer to coat the filaments with a layer containing carbon black.
  • the filament (10) wound on a spindle (101) is reeved around rollers (12) through grafted copolymer (20) in a first tank (11).
  • the grafted copolymer (20) permeates and coats the filament (10).
  • a pair of rollers (12) squeegees excess grafted copolymer (20) from the filament (10).
  • the filament (10) is passed through grafted copolymer (20) in a second tank (13) and a third tank (15) to increase the thickness of the grafted copolymer on the filament (10) to ensure that sufficient the carbon black is on the filament (10).
  • the filament (10) is delivered to a curing roller assembly (17) to completely cure the grafted copolymer on the filament (10).
  • two sheets of a membrane (25) are respectively delivered from two membrane spindles (18) respectively mounted on opposite sides of the filament (10).
  • the membranes (25) are laminated on the filament (10) by a pair of compressing wheels (181).
  • the membrane (25) on the filament (10) keeps the carbon black from easily coming off the filament (10) and provides an insulating layer to complete the electrothermal filament.
  • the electrothermal filaments are winded up on a final roller (19).
  • each electrothermal filament (30) is composed of a conductive core (21) of grafted copolymer and a membrane (25) surrounding around the core (21).
  • the conductive core (21) has two ends projecting out of the membrane (25), and two electrodes (35) are respectively attached to opposite ends of the conductive core (21).
  • the electrothermal filament (30) generates heat when current passes through the conductive core (21).
