The residual concentration of formaldehyde gas was determined 48 hours after the injection. From this measured value, the total amount of the test piece adsorbed and removed formaldehyde was calculated, and the removal rate (%) of formaldehyde was calculated from this value.

(Ammonia removal performance)
The ammonia gas removal rate (%) was calculated in the same manner as the formaldehyde removal performance, except that ammonia gas was used instead of formaldehyde gas and the ammonia gas was injected so that the concentration in the acrylic box was 200 ppm.

(Acetic acid removal performance)
The acetic acid gas removal rate (%) was calculated in the same manner as the formaldehyde removal performance except that acetic acid gas was used instead of formaldehyde gas and the acetic acid gas was injected so that the concentration in the acrylic box was 200 ppm.

<Example>
A pile yarn made of polyester fiber is planted on a base fabric with a tufting machine on a spunbond nonwoven fabric base fabric made of polyester fiber (weighing 110 / m ² ), and a tufted carpet skin layer having a pile length of 7 mm and a pile basis weight of 700 / m ² is applied. Prepared. Next, as a backing resin, 250 parts by mass of calcium carbonate was mixed in 100 parts by mass of SBR (styrene-butadiene copolymer) latex to prepare a backing resin. The backing resin is applied to the underside of the tufted carpet's skin layer by roll coating at 400 g / m ² , and a needle punched nonwoven fabric (3.4 decitex, thickness 3 mm, basis weight 100 g / m ² ) made of polyester fiber is second. The carpet 2 was laminated on the backing resin layer as a base fabric and dried at 150 ° C. for 15 minutes.
The carpet 2 was provided with six through holes for attaching the design cloth 3 by attaching aluminum eyelets having an inner diameter of 8 mm and an outer diameter of 12 mm using a dedicated tool.
As the designable fabric 3, a reversible felt of 100% wool fiber or 80% wool fiber was prepared. As a resin containing functional fine particles to be supported on the design fabric 3, 5 parts by mass of a composition in which sebacic acid dihydrazide and zeolite are mixed in a one-to-one ratio with 100 parts by mass of water, and 10 parts by mass of an acrylic binder resin It melt | dissolved and the deodorizing composition was obtained. The design fabric 3 which carries 5 g / m < ² > of deodorizers by apply | coating 115 g / m < ² > of said deodorant composition to the surface and back surface of the said reversible felt, respectively, and heat-drying at 120 degreeC for 10 minutes. Got reversible felt.
Next, a bird design and a leaf design are prepared, and a depth part 3-1 and a depth part 3-2 are provided for each, and the size of the design fabric 3 of the bird is 18 cm × 6 cm in outer dimensions. The design fabric 3 was a pattern having an outer size of 23 cm × 6 cm. Next, after drawing a line for cutting on the reversible felt of the designable cloth 3 according to the pattern, the sheet is cut with scissors along the line for cutting, and three pieces of the designable cloth 3 for the bird are designed. Three fabrics 3 were obtained.
Subsequently, two of the three design fabrics 3 of the bird bird are moved to the position of the depth region 3-1, one is moved to the position of the depth region 3-2, and three sheets of the design fabric 3 of the leaf One of them was attached to the through hole of the carpet 2 up to the position of the depth part 3-1, and two pieces were attached to the position of the depth part 3-2 to obtain a carpet 1 having a designable fabric.
The carpet 1 having the designable fabric thus obtained hangs on the surface of the carpet 2 while the designable fabric 3 hangs while drawing a curve with the weight of the designable fabric 3 itself, with the penetrating part attached to the carpet 2 as a fulcrum. A carpet with a high design that allows you to interact with each other and become a three-dimensional design expression, enjoy a three-dimensional coordination, and express yourself and share the fun with the people who gather there. did it. In addition, since the design cloth 3 can be exchanged, the range of design expression is widened, and a carpet having high design characteristics can be obtained. As a deodorization removal performance test, the results of measurement using a test piece (10 × 10 cm square) cut out from the carpet including the part where the design fabric 3 of leaves is mounted are as follows. The formaldehyde removal rate is 96% and the ammonia removal rate is 95%. Acetic acid removal rate was 91%, and high deodorizing performance was demonstrated.

<Comparative example>
As a backing resin, 5 parts by weight of a composition in which SBR (styrene-butadiene copolymer, SBR content 50 mass%) latex is mixed with 100 parts by mass of a deodorizing composition in a sebacic acid dihydrazide-zeolite ratio in a one-to-one ratio. Further, a backing resin was prepared by mixing 250 parts by mass of calcium carbonate as a filler.
A tufted carpet skin layer was prepared in the same manner as in the examples, and 115 g / m ² of the same deodorant composition as in the examples was sprayed on the tufted carpet skin layer, and the backing resin was tufted. A carpet was obtained by applying 400 g / m ² by roll coating on the underside of the carpet skin layer. The carpet skin layer and the backing resin layer were coated with 11 g / m ^{2 of} deodorant.
Although the carpet thus obtained can enjoy two-dimensional design coordination, it has not been able to enjoy three-dimensional design expression coordination. As a deodorization removal performance test, the results of measurement using a test piece cut out from a carpet (10 × 10 cm square) were a formaldehyde removal rate of 89%, an ammonia removal rate of 87%, and an acetic acid removal rate of 84%. The result was inferior to the Example.

  Even if the amount of deodorant attached to the design fabric is equal to or less than the amount of deodorant attached to the carpet, the fabric with the deodorant function is more likely to come into contact with the air. Thus, it was confirmed that the deodorizing function was improved.

  The present invention is used as various carpets including rug carpets, tile carpets, and electric carpets.
