Title:
導電性マルチフィラメントおよびそれからなるブラシ
Document Type and Number:
Japanese Patent JP4475036
Kind Code:
B2
Abstract:
To provide brushes having various resistance values according to objectives such as an electrostatic charging brush, a cleaner brush, etc., without changing the specific resistance value of a polyamide multifilament containing electroconductive carbon, and enabling the printing of a high image quality in the case of mounting such the brushes on a copying machine.
This conductive polyamide multifilament yarn containing the conductive carbon and having 106-1012Ωcm specific resistance value and 30-60 % changing rate of logarithmic values of the specific resistance values before and after a hot water treatment is provided by having 0.1-1.0 (S1) standard deviation of logarithmic values of the specific resistance values before a dry heat treatment and also 0.5-0.8 (S2/S1) ratio of the S1 to the standard deviation (S2) of logarithmic values of specific resistance values after the dry heat treatment.
