Hereinafter, preferred embodiments of the present invention will be described in detail in order to facilitate the present invention by those skilled in the art.

The present invention provides a method for manufacturing a sterile wet tissue including a step of immersing a wet tissue for a wet tissue in a stock solution and sterilizing the wet tissue at 100 to 140 DEG C for 1.5 to 3.0 atm for 10 to 60 minutes.

In addition, the present invention may further include packaging the sterilized wet tissue material.

Hereinafter, the production method of the present invention will be described in detail.

First, a material for wet tissue and a stock solution are prepared.

In the present invention, the material for the wet tissue can be generally selected from materials used for wet tissues, non-woven fabric, cotton fabric, and paper.

Preferably, a nonwoven fabric may be used, and more preferably, the nonwoven fabric may be a 100% organic cotton face. Conventionally, rayon / polyester synthetic fibers have been used as a nonwoven fabric for wet tissues or general cotton has been used. However, the present invention introduces a material that has not been treated with chemicals compared to synthetic fibers or general cotton using organic certified cotton.

In the present invention, the undiluted solution may be ultrapure pure water obtained by a reverse osmosis (R / O) method. The ultrapure pure water preferably has a resistance of 18.2 M OMEGA or higher, and the presence of foreign matter, microorganisms, and ions can be suppressed in ultrapure water having a resistance of 18.2 M OMEGA or higher.

Ground and cut the prepared wet tissue material and immerse it in the stock solution. This can be sealed and packaged.

Then, the material for wet tissue immersed in the stock solution is sterilized. The sterilization is carried out at 100 to 140 캜, 1.5 to 3.0 atm for 10 to 60 minutes. At this time, no chemical preservative or chemical is added, and no radiation is applied. That is, by non-chemical and physical sterilization.

The sterilization temperature may be 100-140 캜, more preferably 110-130 캜, and most preferably 121 캜. If the temperature is lower than 100 ° C., the product may not be completely sterilized. If the temperature is higher than 140 ° C., the nonwoven fabric or the packaging material may be deformed.

The sterilizing air pressure may be 1.5 to 3.0 atm (atmospheric pressure) (0.15 to 0.3 MPa), more preferably 1.5 to 2.3 atm. If the air pressure is less than 1.5 atm, the temperature may not sufficiently rise and sterilization may not be performed. If the air pressure is more than 3.0 atm, there is a problem that deformation may occur in the packaging material.

The sterilization time may be 10 to 60 minutes, more preferably 30 to 60 minutes. If the time is less than 10 minutes, the sterilization may not be completed, and if it exceeds 60 minutes, the nonwoven fabric or the packaging material may be deformed.

According to the high-temperature high-pressure sterilization satisfying the above-mentioned temperature, pressure and time conditions, the microorganism sterilization effect is excellent and there is no mold or bacterial infection even after a few days after the production of the product. Such an excellent sterilization effect occurs when the conditions of 100 to 140 DEG C and atmospheric pressure of 1.5 to 3.0 atm are all satisfied.

The sterilization step of the present invention is harmless and safe to the human body since it is physically sterilized at high temperature and high pressure and does not contain any other chemical sterilization or irradiation.

Thereafter, the material for the wet tissue as described above is packed.

That is, it can be sterilized and packed in the manufacturing process of the wetted wipes before packaging. According to the prior art, the wipes are packaged after the wipes are manufactured, and then the radiation (gamma ray) sterilization is carried out. However, the present invention can have a manufacturing advantage by proceeding the packaging after sterilization.

The present invention also provides a sterile wet tissue produced according to the above-described method.

The sterilized wet tissue of the present invention was confirmed to be free of mold and bacterial infection in the microorganism test conducted 15 days or more after the preparation (see Experimental Example 1).

The sterilized wet tissue according to the present invention is excellent in sterilization effect and is harmless and safe to human body, so that it is not particularly limited, but it can be used as an oral wet tissue, a newborn baby wet tissue or a baby wet tissue, which are sensitive to bacteria.

The present invention will be described in more detail through the following examples. However, the examples are for illustrating the present invention, and the scope of the present invention is not limited thereto.
