Abstract (en)
The melt-spun thread useful in screen textiles and filter cloths for gas and fluid filters, comprises a thermoplastic polymer, a thermoplastic elastomer block copolymer, and soot particle in the form of aggregates aligned along the longitudinal axis of the thread. The aggregates form electrically conductive paths along the longitudinal axis of the thread. The thread is a core-skin or monofilament and has a modulus of elasticity of 0.1-5.5 GPa and an elastic elongation of greater than 1.5-4%. The aggregates are formed from primary particles connected with each other. The melt-spun thread useful in screen textiles and filter cloths for gas and fluid filters, comprises a thermoplastic polymer, a thermoplastic elastomer block copolymer, and soot particle in the form of aggregates aligned along the longitudinal axis of the thread. The aggregates form electrically conductive paths along the longitudinal axis of the thread. The thread is a core-skin or monofilament and has a modulus of elasticity of 0.1-5.5 GPa and an elastic elongation of greater than 1.5-4%. The aggregates are formed from primary particles connected with each other. The soot particle causes electrical conductivity of the thread of 1.0-10 ->5>Siemens/cm measured in the longitudinal direction of the thread. The core is formed from thermoplastic polymer. The weight ratio of core and skin is 70:30 to 50:50. An independent claim is included for textile surface structure such as fabric.
Abstract (de)
Beschrieben werden schmelzgesponnene Fäden mit einem Elastizitätsmodul von 8 bis 14 GPa und einer elastischen Dehnung von bis zu 1,5 % enthaltend a) einen thermoplastischen Polyester, b) ein thermoplastisches elastomeres Block-Copolymer, und c) Ruß- und/oder Graphitteilchen in der Form von entlang der Längsachse des Fadens ausgerichteten Aggregaten, welche entlang der Längsachse des Fadens elektrisch leitfähige Pfade bilden. Die Fäden weisen eine sehr hohe elektrische Leitfähigkeit auf, und lassen sich zur Herstellung von Sieben oder anderen technischen Geweben einsetzen.
