Abstract

A wiping cloth removes microbes and is capable of picking up dirt from the wiped surface of an object and trapping the dirt into the cloth to ensure the retention of the trapped dirt. The wiping cloth is made of a fabric including 50 to 80% by weight of synthetic microfibers with a single fiber fineness of below 1.0 dtex and having a bulk of 2.0 cm 3 /gr or more.

Claims

exact text as granted — not AI-modified
1 .- 9 . (canceled) 
     
     
         10 . A wiping cloth for removing microbes, the wiping cloth made of a fabric comprising 50 to 80% by weight of synthetic microfibers with a single fiber fineness of below 1.0 dtex and having a bulk of 2.0 cm 3 /g or more. 
     
     
         11 . The wiping cloth according to  claim 10 , wherein the single fiber fineness of the synthetic microfibers is 0.1 dtex or less. 
     
     
         12 . The wiping cloth according to  claim 10 , wherein the fabric comprises high shrinkage fibers. 
     
     
         13 . The wiping cloth according to  claim 10 , wherein at least some of the fibers in the fabric are false-twisted. 
     
     
         14 . The wiping cloth according to  claim 10 , wherein the fabric is treated by water jet punching. 
     
     
         15 . The wiping cloth according to  claim 10 , made of a fabric made from a composite yarn consisting of 50 to 80% by weight of synthetic microfibers with a single fiber fineness of below 1.0 dtex and 50 to 20% by weight of synthetic high denier fibers with a single fiber fineness of 1 dtex or more. 
     
     
         16 . The wiping cloth according to  claim 15 , wherein the single fiber fineness of the synthetic microfibers is 0.1 dtex or less. 
     
     
         17 . The wiping cloth according to  claim 10 , which has an ATP level of 100 RLU or less, the ATP level serving as an indicator of an amount of dirt in accordance with the abundance of organisms. 
     
     
         18 . A method of removing microbes comprising wiping with the wiping cloth according to  claim 10  that is wetted with water. 
     
     
         19 . The wiping cloth according to  claim 11 , wherein the fabric comprises high shrinkage fibers. 
     
     
         20 . The wiping cloth according to  claim 11 , wherein at least some of the fibers in the fabric are false-twisted. 
     
     
         21 . The wiping cloth according to  claim 11 , wherein the fabric is treated by water jet punching. 
     
     
         22 . The wiping cloth according to  claim 11 , which has an ATP level of 100 RLU or less, the ATP level serving as an indicator of an amount of dirt in accordance with the abundance of organisms. 
     
     
         23 . A method of removing microbes comprising wiping with the wiping cloth according to  claim 11  that is wetted with water.
