Fabric Deodorant  evaluation

In this experiment, the deodorizing properties of the cotton fabric prepared in Example 1 and Comparative Examples 1 to 3 were evaluated.

In order to evaluate the deodorization property, 1 liter of the total amount of ammonia (500 ppm) as the initial concentration of the odor component was sealed in a Tedlar bag together with a sample of 1 g of the sample (fabric of 10 cm x 10 cm) The residual concentration was measured by using a detection tube under the conditions of a temperature of 21 캜 and a humidity of 37% as a test environment. As a blank test, the same measurement was carried out without adding a sample, and the deodorization rate was calculated by the following equation.

Deodorization rate (%) = [(Blank gas concentration-Sample gas concentration) / Blank gas concentration] × 100

As a result, as shown in FIG. 2 and the following Table 1, in the case of the cotton fabric coated with the mixture of the Asian ticoside and chitosan of the present invention, the deodorization rate was excellent at the early stage of odor generation and the deodorization rate was 54% , Which showed a remarkably superior deodorization rate to the cotton fabrics prepared in Comparative Examples 1 to 3.

Generally, in the case of the needle material, the function of removing the odor in a short period of time is essential, so that the fabric of the present invention having a fast deodorization rate at the initial stage of the smell can be effectively used for the needle material.

For reference, the increase in the deodorization rate over time in Comparative Examples 1 to 3 is due to the natural adsorption of the odor depending on the adsorption function of the material over time.

Therefore, in order to evaluate the pure deodorization rate of the fabric, it is the most important requirement to effectively remove the odor at the early stage of the odor generation. In this respect, the fabric manufactured in Example 1 of the present invention is compared with Comparative Examples 1 to 3 It can be said that it shows a remarkable excellent deodorization rate.
