<p><P>PROBLEM TO BE SOLVED: To produce a cleaning web which little causes orientation or fuzzing and exhibits a high maximum tolerable temperature, low water absorption, and strong affinity for oil and which attains prescribed cleaning characteristics without using a binder in the forming of the web. <P>SOLUTION: The web for cleaning the surface of a member to be cleaned which is produced by impregnating a non-woven fabric with an oil, wherein the non-woven fabric is a meltblown one which comprises as the main component a wholly aromatic polyester that can form a liquid crystal in melting and exhibits a melt viscosity of 20 Pa s or below at 310°C and which has a mean fiber diameter of 3 to 15μm, a thickness of 20 to 80μm, an average basis weight of 9 to 30 g/m<SP>2</SP>, a density of 0.25 to 1.4 g/cm<SP>3</SP>, a lengthwise tensile strength/widthwise tensile strength ratio of 1.0 to 4.0, and lengthwise and widthwise elongations of about 3%. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
