Abstract

The invention discloses a novel composite conductive fiber with elasticity. The novel composite conductive fiber is of a three component composite structure, wherein a sheath-core composite structure is formed by a component 1 and a component 2; and the novel composite conductive fiber is obtained via combination of the sheath-core composite structure with a component 3. The component 1 is water soluble polyester; the component 2 is polyester PET containing conductive powder; and the component 3 is PTT or PBT. Weight ratio of the component 1 to the component 2 is 10:90-70:30; weight ratio of the component 3 to the component 2 is 30:70-70:30; and the amount of the conductive powder accounts for 20 to 50% of weight of the component 2. The novel composite conductive fiber is subjected to alkali treatment, so that water soluble polyester is removed, and PET / PTT or PET / PBT juxtaposed composite conductive fiber is obtained; conductivity of the PET / PTT or PET / PBT juxtaposed composite conductive fiber is excellent; the PET / PTT or PET / PBT juxtaposed composite conductive fiber possesses spiral-shaped permanent resilience, can be made into filament yarn and short fiber, can be widely used for various sport wear, coats, working clothes, and filling materials, and possesses excellent antistatic effect and elasticity.

Description

technical field [0001] The invention belongs to the field of novel functional fibers, and in particular relates to a composite fiber with excellent electrical conductivity and permanent elasticity. Background technique [0002] Synthetic fibers generally have superior electrical insulation properties. However, the higher the electrical insulation performance, the greater the resistance, and the easier it is to generate high static electricity. When the static electricity accumulates to a certain extent, it will be discharged, and there is a danger of explosion and fire in certain occasions. Therefore, antistatic fibers and conductive fibers are widely used and become indispensable varieties in differentiated fibers. With the promotion and expansion of their application fields, different application environments and novel fabric designs will affect the performance of conductive fibers. put forward higher requirements. [0003] Usually, conductive fibers are formed by carbon...
