摘要： Provided is a cleaning web produced without use of a binder that is superior in smoothness, release efficiency and orientation, resistant to fluffing, having a high heat-resistance temperature, superior in low water-absorption and compatible with oils, and having particular cleaning characteristics.
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 and has an average fiber diameter of 3 µm or more and 15 µm or less, a thickness of 20 µm or more and 80 µm or less, an average basis weight of 9 g/m 2 or more and 30 g/m 2 or less, a density of 0.25 g/cm 3 or more and 1.4 g/cm 3 or less, a maximum tensile stress in the machine and crosswise directions of 1.0(N/1.5cm) or more and 4.0(N/1.5cm) or less, and an elongation in the machine and crosswise directions of approximately 3%.摘要翻译： 本发明提供一种清洁网而不使用粘合剂的产生确实是在平滑性，释放效率和取向优越，能起毛，具有高耐热温度，优异的低吸水性和与油相容，并且具有特定的清洁特性耐 ， 用于清洁的物品的表面的清洁卷筒纸被清洗，通过浸渍卷筒纸用于清洁的物品的表面上产生与在油将被清洁，worin幅材是含有熔融液晶形成性全芳香族聚酯的非织造织物 作为主要成分，通过熔喷法制造并且对的3微米以上，15微米或更小，厚度为20微米或平均纤维直径为20帕·秒或在310℃以下的熔融粘度 以上且80微米以下，在为9g / m 2以上且为30g / m 2或更小，为0.25g / cm 3以上和1.4g / cm 3以下，最大拉伸的密度平均单位面积重量 应力在纵向和1.0（N /1.5厘米）以上且4.0（N /1.5厘米）或更小的横向方向，并且在机器和横向的大约3％的方向伸长。

摘要： Use of an electrically charged nonwoven fabric that is made of a fiber predominantly composed of an amorphous polymer provides a novel filtration material having improved performances compared to those of conventional filtration materials and having excellent heat resistance and excellent flame retardancy as well as an electrically charged nonwoven fabric for use in the filtration material. It is preferable that the surface charge density is greater than or equal to 1 × 10 -10 coulomb/cm 2 . It is preferable that the collection efficiency for collecting a dust particle with a particle diameter of 1 µm flowing at a fabric-passing velocity of 8.6 cm/second is greater than or equal to 40%, the QF value is greater than or equal to 0.05, and the decrement of the dust-particle collection efficiency after being allowed to leave at 100°C for 24 hours is less than or equal to 10%. The present invention also provides a filtration material including the electrically charged nonwoven fabric and a method for producing the electrically charged nonwoven fabric.
