Manufacturing method for manufacturing a cotton-containing product

Abstract

In order to manufacture a cotton-containing product of a cotton material, when the cotton material is refined and bleached in the state of a sliver, heating is performed, with steam, on the cotton material with a chemical agent applied to the cotton material, and, when the heating is performed, the steam is applied to the cotton material in the state of a sliver sheet formed by arranging the sliver in a sheet shape.

1 . A manufacturing method for manufacturing a cotton-containing product of a cotton material, comprising refining and bleaching the cotton material in a state of a sliver, wherein, when the refining and the bleaching are each performed, heating is performed, with steam, on the cotton material with a chemical agent applied to the cotton material, and wherein, when the heating is performed, the steam is applied to the cotton material in a state of a sliver sheet formed by arranging the sliver in a sheet shape.

         3 . (canceled) 
     
     
         4 . The manufacturing method according to  claim 1 , further comprising, after the sliver sheet is heated by applying the steam to the sliver sheet, washing the sliver sheet while the sliver sheet is being conveyed by at least one perforated conveying medium. 
     
     
         5 . The manufacturing method according to  claim 4 , wherein the at least one perforated conveying medium comprises two perforated conveying media comprising inner and outer mesh conveyors,
 wherein a perforated drum is immersed in a washing liquid,   wherein the inner conveyor is disposed inside of the sliver sheet, and the outer conveyor is disposed outside of the sliver sheet, and   wherein the washing of the sliver sheet comprises sucking a washing liquid in the perforated drum while conveying the sliver sheet along an outer periphery of the perforated drum, with the sliver sheet sandwiched between the inner mesh conveyor and the outer mesh conveyor, and passing the sucked washing liquid from outside of the outer conveyor through the outer mesh conveyor, then through the sliver sheet, then through the inner conveyor, and then through the perforated drum.   
     
     
         6 . The manufacturing method according to  claim 1 , wherein, after the bleaching is finished, a function is applied to the cotton material in the state of the sliver. 
     
     
         7 . The manufacturing method according to  claim 1 , wherein after the bleaching, the sliver is spun into thread.

         9 . (canceled) 
     
     
         10 . A washing machine of a suction type comprising:
 a perforated drum immersed in a washing liquid;   a suction device configured to suck the washing liquid from inside of the perforated drum;   a pair of inner and outer mesh conveyors between which a sliver sheet is to be sandwiched; and   a conveyor guiding device for conveying the sliver sheet along an outer periphery of the perforated drum, while sandwiching the sliver sheet between the inner mesh conveyor and the outer mesh conveyor, with the inner mesh conveyor disposed inside of the sliver sheet and the outer mesh conveyor disposed outside of the sliver sheet,   wherein the suction device is configured to suck a washing liquid in the perforated drum, and pass the sucked washing liquid from outside of the outer mesh conveyor through the outer mesh conveyor, then through the sliver sheet, then through the inner conveyor, and then through the perforated drum, thereby washing the sliver sheet.   
     
     
         11 . A production line for a cotton-containing product of a cotton material, wherein a refining step and a bleaching step are continuously performed on the cotton material, and
 wherein, in at least one of the refining step and the bleaching step, the production line includes:   a steamer configured to heat a sliver sheet of the cotton material by applying steam to the sliver sheet after immersing the sliver sheet in a liquid; and   the washing machine of the suction type according to  claim 10 , which is configured to wash the sliver sheet after the heating.   
     
     
         12 . The manufacturing method according to  claim 4 , wherein, after the bleaching is finished, a function is applied to the cotton material in the state of the sliver. 
     
     
         13 . The manufacturing method according to  claim 5 , wherein, after the bleaching is finished, a function is applied to the cotton material in the state of the sliver. 
     
     
         14 . The manufacturing method according to  claim 4 , wherein after the bleaching, the sliver is spun into thread. 
     
     
         15 . The manufacturing method according to  claim 5 , wherein after the bleaching, the sliver is spun into thread. 
     
     
         16 . The manufacturing method according to  claim 12 , wherein after the bleaching, the sliver is spun into thread. 
     
     
         17 . The manufacturing method according to  claim 13 , wherein after the bleaching, the sliver is spun into thread. 
     
     
         18 . A production line for a cotton-containing product of a cotton material, wherein a refining step and a bleaching step are continuously performed on the cotton material, and
 wherein, in at least one of the refining step and the bleaching step, the production line includes a steamer configured to heat a sliver sheet of the cotton material by applying steam to the sliver sheet after immersing the sliver sheet in a liquid.
