Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nonwoven fabric having excellent antibacterial and deodorant properties and a method for producing the same.

The present invention relates to a nonwoven fabric excellent in antibacterial and deodorant properties and a method for producing the same, and relates to a nonwoven fabric having excellent antimicrobial and anti-odor properties imparting antimicrobial and deodorant properties in the production of a nonwoven fabric using a water- .

The nonwoven fabric is made of felt in the form of a felt, which is arranged in parallel or in an indefinite direction without being subjected to a woven process, and is formed by a physical method such as a synthetic resin adhesive, heat fusion, needle punching or high pressure water. And recently, it has been widely used for tissues, cloths, towels and the like which are used for disposable use.

In addition, efforts have been made to impart antibacterial properties to textile products in order to improve the environmental pollution, and efforts to impart antibacterial properties to nonwoven fabrics have been continued.

In the early days of antimicrobial processing, antimicrobial agents were largely divided into aromatic halogen compounds, organic silicon quaternary ammonium salts and other compounds. However, since the field of antimicrobial processing has been expanded, various antibacterial deodorants have been recently developed. Of these, the most commonly used are inorganic particles containing metal or metal, quaternary ammonium salts and organic quaternary ammonium salts. This is because the cell wall is destroyed and removed, microorganisms die, and proliferation is suppressed.

In Korean Utility Model No. 0262773, silver is pulverized into ultrafine powder, which is mixed with a transparent ink and a binder in a certain ratio to the human body. The silver powder is attached to the surface of the silver powder by the silk screen printing, The nonwoven fabric sheet substrate is bonded to the upper surface of the nonwoven fabric sheet with an adhesive and is thermally fused to impart antibacterial properties to the nonwoven fabric through antimicrobial activity of silver.

Korean Patent No. 0624069 discloses an antimicrobial product obtained by treating a nano-sized silver colloid solution, which is an inorganic metal material having excellent antibacterial function

However, since some aromatic halogen compounds have a problem in safety, they are not used at present. Antimicrobial processing methods using metal ions or metals in the past proceed to post-processing after fabric preparation, and the economical efficiency of the antibacterial agent, In particular, in the case of a nonwoven fabric used as a sanitizer, inorganic substances such as silver are easily removed and are difficult to apply, and nano-sized inorganic substances are being used for safety reasons.
