Wiping cloth, method of manufacturing wiping cloth, wiping belt, method of manufacturing wiping belt, and thermal cutting device for wiping belt.

Abstract

This invention relates to a wiping cloth, which is constructed from a fibrous structure using ultrafine polyamide fibers. The fineness of the single yarn of the ultrafine polyamide fibers is 0.7 dtex or less, the content of ultrafine polyamide fibers in the wiping cloth as a whole is 40% by mass or more, and the average number of airborne particles with a diameter of 0.1 μm or more is 10 particles / cm² or less. This invention also relates to a wiping strip, which, when immersed in pure water for 12 hours in a Class 100 environment, has a particle count of 0.2 μm or more in the liquid of 5 particles / ml / cm² or less. Furthermore, this invention relates to a method for manufacturing a wiping strip, characterized by: thermally cutting the fabric for the wiping strip in a cleanroom, and immediately after thermal cutting, using a suction nozzle to remove the fumes generated during thermal cutting. none
