- both the deodorant performance and antibacterial performance were not sufficient. Disclosure of the invention
- the present invention has been made in view of the above circumstances, and provides a deodorant and antibacterial powder which has a high-performance deodorant and antibacterial effect against various odors and various bacteria and can be used in a wide range of fields. It is intended for that purpose.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, obtained as a hydrate of calcium oxide obtained by calcining a shell, having a specific average particle size. Calcium hydrate powder was found to be effective in deodorizing and antibacterial. The present invention has been completed based on such findings.

- Examples of the shell used in the deodorant / antibacterial powder preparation of the present invention include shells such as scallop, clam, clam, oyster, turtle, abalone and mussel. Of these, scallop and oyster shells, which are industrially processed at a high rate, are preferred because they are easily available, and furthermore, they have a low impurity content and can effectively use a large amount of waste. Therefore, scallop shells are preferred. Calcium oxide obtained by sintering shells contains trace metals such as zinc, iron, and magnesium, and thus is suitable for imparting antibacterial properties.
- the shell is baked at 800 to 130 ° C for 3 to 6 hours after washing the shell with water. After firing, remove fine sand etc. from the fired product and add water to hydrate calcium oxide.

- Comparative Example 8 Calcium oxide hydrate powder (deodorant / antibacterial powder formulation) having an average particle size of 10 ⁇ was blended with Acryl Emulsion (Crosslen, manufactured by Ganz Kasei Co., Ltd.) to prepare a fiber treatment agent.
- Deodorant ⁇ The compounding amount of the antibacterial powder preparation was 50% by mass based on the dry mass of the fiber treatment agent.
- the fiber treatment agent was laminated on a polyester base fabric using a roll coater 1, dried at 100 ° C for 30 minutes, and the fiber treatment agent was applied in a dry mass of 0.5 g Zm 2 .
- Deodorization An antibacterial polyester base fabric was manufactured. A sample of 5 cm ⁇ 5 cm was cut out from this base cloth, and the formaldehyde concentration was measured in the same manner as in Example 1. As a result, it was 2 ppm by mass.
- Calcium oxide hydrate powder (deodorant / antibacterial powder formulation) having an average particle size of 10 ⁇ was blended with Acryl Emulsion (Croslen, Ganz Kasei Co., Ltd.) to prepare a fiber treatment agent.
- Deodorant ⁇ The compounding amount of the antibacterial powder preparation was 50% by mass based on the dry mass of the fiber treatment agent.
- the above-mentioned fiber treating agent was laminated on a polyester base fabric with a roll coater and dried at 100 ° C. for 30 minutes, and the fiber treating agent was applied at a dry mass of 58 g / m 2. An odor- and antibacterial-imparting polyester-based fabric was manufactured.
- the deodorant / antibacterial powder of the present invention has a high-performance deodorant and antibacterial effect against various odors and various bacteria, and can be used in a wide range of fields.
