Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antibacterial fiber, a filler comprising the same, and bedding using the filler. More specifically, a microorganism that inhibits the growth of harmful microorganisms is used for a long time on the fiber surface. The present invention relates to an antibacterial fiber capable of effectively inhibiting the growth of harmful microorganisms that retain and grow in the environment and generate a foul odor, etc., and a filler made of the fiber, and bedding using the filler.

[0002]

2. Description of the Related Art In bedding, harmful microorganisms propagate due to sweat and waste products emitted from the human body during sleep, and the microorganisms decompose organic substances contained in sweat and waste products to generate unpleasant odors and mite. May cause dermatitis and other harmful insects to reproduce. Pseudomonas spp, Serratia spp, Alcaligenes spp, Arterinaria spp, Aspergius spp, Penicillium spp, etc. are known as harmful microorganisms causing such problems.

As a solution to such a problem, Japanese Patent Laid-Open No.
Japanese Patent No. 234208 discloses a method in which an aqueous suspension of aerobic microorganisms that inhibits the growth of harmful microorganisms is applied to a filler such as feathers, a foam such as polyurethane foam, a side cloth, a blanket, sheets, etc., and then dried, , A method of incorporating a sheet-like material obtained by impregnating and drying a non-woven fabric, paper or the like into bedding.

[0004]

However, as fillers for bedding and the like, synthetic fibers such as polyester and polypropylene and acrylic occupy a considerably large weight, and these synthetic fibers are treated by the above method. Even if the aerobic microorganisms are applied to the fiber surface and dried, they drop off from the fiber surface in a short period of time or die due to lack of nutrient sources,
It is impossible to prevent the growth of harmful microorganisms for a long period of time and prevent the generation of offensive odors. In the case of feathers, the surface is uneven, and the proteins and lipids that make up the feathers serve as nutritional sources. Although the above problems are alleviated, they are not always sufficient.

The present invention solves the above problems and prevents useful microorganisms from sufficiently staying and growing on the surface of the fiber and preventing them from dropping or dying for a long period of time, preventing the growth of harmful microorganisms, and generating an offensive odor. The present invention provides an antibacterial fiber capable of blocking, a filler made of the same, and bedding using the filler.
