Description

  The present invention relates to carpet detergents. More specifically, the present invention relates to a carpet detergent that has excellent detergency and a sufficient softening effect.

  In recent years, floor carpeting has been progressing in newly built offices and mass retailers. As daily maintenance for the carpets laid, dust removal is mainly performed by vacuuming. By this vacuum operation, dust and non-adherent residues such as dust on the carpet can be easily removed. However, in this vacuum operation, it is difficult to remove adhesive residues such as oil stains. Further, dirt adheres to such adhesive residue, and accumulation of dirt occurs. Further, in a portion where pressure is concentrated by walking or the like, the pile is crushed and the aesthetics are lowered. Furthermore, dirt in the pile that has been crushed is difficult to remove by the vacuum operation. As a result, dirt is likely to accumulate in a portion where pressure is concentrated by walking or the like.

  About once a year, cleaning is performed to remove accumulated dirt. As this cleaning method, shampoo cleaning (a two-step method using a polisher and an extractor) having a strong cleaning power is the mainstream. As a detergent used for this cleaning, for example, a carpet detergent having an anionic and nonionic surfactant as a detergent component that has cleaning properties, has no stickiness after drying, and has little fear of recontamination is used. (For example, see Patent Document 1).

JP-A-2-255900

  However, the cleaning properties of conventional carpet detergents such as Patent Document 1 are still insufficient, and further improvements in cleaning properties are required. Further, the conventional carpet detergent has a problem that it does not have an effect of imparting flexibility to the object to be cleaned (flexibility effect), and the pile of the crushed carpet cannot be restored. Therefore, a carpet detergent that can solve this problem is also desired.

  An object of the present invention is to provide a carpet detergent that is excellent in cleanability and can provide a sufficient softening effect.

[2] Performance evaluation of carpet detergent The following performance evaluation was performed using each carpet detergent of Examples 1-10 and Comparative Examples 1-9. The results are also shown in Tables 1 and 2.

(1) Detergency New tile carpet [manufactured by Tajima Co., Ltd., trade name “Tapis Select 450-882”, dimension: 50 cm × 50 cm], artificial dirt (JISL1023 8.1, “Standard for carpet dirt test”) Contaminants ”) 16 g / m ² was uniformly applied and then cut into 5 cm × 25 cm to obtain test pieces. Moreover, each carpet detergent of an Example and a comparative example was diluted 20 times with tap water, and it was set as the test detergent liquid. Subsequently, the test piece was set in a washing tester (washer tester, 19 of JISK39920) equipped with a pork brush. Thereafter, 10 ml of the test detergent solution was sprayed on the test piece and then washed 50 times. After washing, the extractor was washed with water for 5 seconds (once) and then naturally dried. And the brightness (L value) before and after cleaning of the test piece was measured, and the cleaning rate was calculated by the following formula.
Cleaning rate (%) = (L3−L2) / (L1−L2) × 100
L1: Lightness before applying dirt L2: Lightness after applying dirt (before washing) L3: Lightness after washing

(2) Flexibility Tile carpet [made by Tajima Co., Ltd., trade name “Tapis Select 450-882”, dimension: 50 cm × 50 cm] used for one year in an office passage and crushed in a pile is cut into 5 cm × 25 cm. A test piece was obtained. Moreover, each carpet detergent of an Example and a comparative example was diluted 20 times with tap water, and it was set as the test detergent liquid. Next, the test piece was immersed in the test detergent solution for 1 minute, then washed with water for 5 seconds (once) by an extractor, and then naturally dried. And the thickness of the carpet before and behind a process was measured, and the thickness recovery rate of the carpet was computed by the following formula.
Carpet thickness recovery rate (%) = (H3−H2) × 100 / (H1−H2)
H1; New carpet thickness (6.5mm)
H2: the thickness of the crushed carpet (5.2 mm)
H3: Heat of carpet after processing (mm)

[3] Effects of Examples From Table 2, in Comparative Example 9 containing only water, the cleaning rate was 5%, the carpet thickness recovery rate was 0%, and the cleaning properties and the softening effect were poor. In Comparative Examples 4 to 6 containing no detergent component and Comparative Example 8 containing a small amount of detergent component, the carpet thickness recovery rate was 70%, but the washing rate was as low as 5 to 20%. On the other hand, in Comparative Examples 2 and 3 in which the softener component was not contained, and in Comparative Example 7 in which the softener component content was small, the cleaning rate was 80 to 90%, but the carpet thickness recovery rate was 5%. It was as low as -10%. In Comparative Example 1 containing an anionic activator as a detergent component, the washing rate was as low as 10%, and the carpet thickness recovery rate was also as low as 5%.

  On the other hand, from Table 1, in the carpet detergents of Examples 1 to 10 included in the scope of the present invention, the cleaning rate is excellent as 70 to 95%, and the carpet thickness recovery rate is 50 to 90%. And was excellent. In particular, in Examples 1 to 5 and 8 to 10 containing specific amounts of the detergent component and the softener component, the washing rate is very excellent at 90 to 95%, and the carpet thickness recovery rate is also 80 to 90. % And was very good.

  From the above, it can be seen that the carpet detergent of this example can sufficiently remove stains on the carpet and has excellent cleaning properties. Moreover, the carpet detergent of a present Example can fully restore | restore the pile which was crushed, and it turns out that sufficient softening effect is acquired.
