Abstract

Mass production of carpet tiles can be enabled by a method for manufacturing a carpet tile by applying an adhesive layer to a carpet tile base material containing pile, the method including: a first process of mixing 15 to 25 wt. % of urethane resin glue to an acrylic foamed resin to produce 100 wt. % of a mixture, thereby obtaining an adhesive; a second process of subjecting the adhesive to viscosity adjustment to adjust viscosity thereof to 3000 to 6000 cps; and a third process of applying the adhesive to the carpet tile base material by using a screen mesh having a mesh thickness of 20 μm or more and less than 100 μm and an opening area ratio of 40% to 60%.

1 .- 6 . (canceled) 
     
     
         7 . A carpet tile comprising
 a base material integrated with a base fabric and a pile, the pile being driven into the base fabric;   an adhesive applied to a surface of the base material facing away from a surface of the base fabric into which the pile is driven,   wherein the adhesive has a viscosity of 3000 cps or more to 6000 cps or less and produced by mixing 15 to 25 wt. % of urethane resin glue with an acrylic foamed resin to produce 100 wt. % of a mixture and adding 10 to 20 wt. % of a viscosity reducer to 100 wt. % of the mixture.
