Method of producing cleaning web, image-forming device and fixing device

摘要

A cleaning web for cleaning the surface of articles to be cleaned, produced by impregnating a web for cleaning the surface of articles to be cleaned with an oil, wherein the web is a nonwoven fabric containing a melt-liquid-crystal-forming wholly aromatic polyester having a melt viscosity of 20 Pa·s or less at 310° C. as the principal component that is produced by melt-blown method.

1. A method of producing a cleaning web characterized by impregnating a web for cleaning the surface of articles to be cleaned with an oil, wherein
the web is a nonwoven fabric containing a melt-liquid-crystal-forming wholly aromatic polyester having a melt viscosity of 20 Pa·s or less at 310° C. as the principal component that is produced by melt-blown method and has an average fiber diameter of from 3 to 15 μm, a thickness of from 20 to 80 μm, an average basis weight of from 9 to 30 g/m2, a density of from 0.25 to 1.4 g/cm3, a tensile stress in the vertical and crosswise directions of from 1.0 to 4.0(N/1.5 cm), and an elongation in the vertical and crosswise directions of approximately 3%, wherein the thermal deformation temperature of the web is 280° C. or higher and the nonwoven fabric is impregnated with the oil at an elastomer roll side when the nonwoven fabric is heated under pressure and conveyed through a space between a metal roll and the elastomer roll.
