Abstract

An object of the present invention is to provide a carpet exhibiting excellent antifouling property against both dry soil and wet soil. The carpet is a carpet including a pile yarn having a coated pile single yarn, in which the coated pile single yarn is a pile single yarn to which a layer A containing organopolysiloxane and a fluorine-based compound is attached, a fineness of the coated pile single yarn is 8 to 40 dtex, a crimp elongation of the pile yarn is 10% to 30%, a carpet staining degree (ΔE) in an antifouling dry test is 30 or less, and a carpet staining degree (ΔE) in an antifouling wet test is 30 or less.

First claim

The invention claimed is:

1. A carpet comprising a pile yarn having a coated pile single yarn, wherein
the coated pile single yarn is a pile single polyamide yarn on which is coated a layer A containing an organopolysiloxane that contains
a cation-modified organosilicate,
a fluorine-based compound that contains a perfluoroalkyl group having 1 to 6 carbon atoms, is nonionic and has a siloxane bond, and
a cured melamine resin, wherein the fluorine-based compound and curded resin are each 1 to 100 parts by mass with respect to 10 parts by mass of the orgaopolysiloxane,

wherein the coated pile single yarn has
a fineness of 8 to 40 dtex,

wherein the pile yarn has
a crimp elongation of 10% to 30%, and

wherein the carpet has
a carpet staining degree (ΔE) in an antifouling dry test of 21 or less, and
a carpet staining degree (ΔE) in an antifouling wet test of 30 or less.

2. The carpet according to claim 1 , wherein a degree of deformation of the coated pile single yarn is 1.1 to 5.0.

3. The carpet according to claim 1 , the carpet staining degree (ΔE) in an antifouling dry test is 10 or less.

4. The carpet according to claim 1 , the carpet staining degree (ΔE) in an antifouling wet test is 15 or less.

5. A method for manufacturing the carpet according to claim 1 , the method comprising:
a first step of obtaining a carpet layer including a pile yarn having a pile single polyamide yarn and a primary base fabric;
a second step of impregnating the carpet layer with a precursor solution containing a cation-modified organosilicate, a non-ionic fluorine-based compound that has a perfluoroalkyl group having 1 to 6 carbon atoms and has a siloxane bond, and an uncured resin that is a precursor of a cured melamine resin; and
a final step of curing the precursor solution to form a layer A on the carpet layer.
