Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid absorbent wick for heating and evaporation of fragrance and a method for producing the same, and more specifically, it imparts a stable fragrance, perfume strength and porosity capable of maintaining transpiration amount for a long period of time. The present invention also relates to a liquid absorbent wick for heating and vaporizing an aromatic and a method for producing the same.

2. Description of the Related Art Conventionally, as a liquid absorbent core for volatilizing chemicals including an aromatic agent at room temperature, as disclosed in Japanese Patent Application Laid-Open No. 2-200137, a single yarn thickness is 5 to 20 denier. A sliver made of acrylic resin fibers was bonded and molded with a melamine resin, and a non-heated volatilization liquid absorbent core having a porosity of 40% to 60% was used.

The above-mentioned conventional fragrance absorbent core for non-heated fragrance is used to suck up the drug solution to its upper end by capillarity from its lower end immersed in the fragrance drug solution and to volatilize it around. However, since the chemical solution requires a high-molecular activator in order to mix water with the fragrance, it causes clogging when the porosity is low. Further, if the porosity of the fragrance absorbent wick for the non-heated fragrance is 40% or less, the wicking amount of the fragrance liquid inevitably decreases under the non-heated state, and the fragrance effect itself deteriorates. Was also considered. Therefore, the porosity of the aromatic liquid has been required to be 40% to 60% in order to suck up the aromatic liquid chemical well and to volatilize it sufficiently under non-heating conditions.

On the other hand, an absorbent wick for heating and vaporizing an insecticide as a heating type absorbent wick has been proposed in, for example, Japanese Patent Application Laid-Open No. 4-308501. This pesticide absorbent vaporization wick is made of synthetic resin fiber such as acrylic, nylon, ester, etc. with a single yarn thickness of about 3 denier, and a top or sliver made of thermosetting resin such as melamine, phenol, urea, etc. It was adhered and molded in and the porosity was set to 12% to 18%.

The above-mentioned insecticide drug solution using the absorbent wick for heating and vaporizing the insecticide comprises, for example, a commercially available insecticide stock solution diluted with kerosene having a content of about 97% to 99% together with some fragrance. Therefore, the chemical liquid sucked up from the lower end portion of the insecticide heating evaporation liquid absorbent core immersed in the insecticide chemical liquid to its upper end portion by capillary action is arranged so as to surround the vicinity of the upper end portion. When heated to about 140 ° C. or lower by the heating means, the insecticidal effect was exhibited by radiating to the surrounding area with an appropriate transpiration amount and duration.

[0006]

In order to continuously supply the fragrance to the surroundings, it is preferable to use the method of heating and evaporating. For that reason, the fragrance is of good quality especially in terms of fragrance and fragrance strength. Has been requested. However, in the liquid core for insecticide heating evaporation, which does not use polymers (excluding thermosetting resin adhesives) that can be used in conventionally well-known solutions,
We couldn't get anything to meet this requirement.

In particular, in the development of a liquid absorbent core for heat evaporation of an aromatic, no matter how the same porosity was used, the perfume could always have the same stable fragrance, fragrance strength and transpiration amount even if the boiling point of the fragrance varied. It was an important issue to be solved whether to obtain an absorbent core that can be maintained for a long time. In addition to that, there has been a demand for the development of a technique for stably manufacturing a large amount of liquid absorbent cores that maintain a desired liquid absorbing property.

The present invention solves the above-mentioned problems of the conventional non-heated volatile liquid absorbent wick and volatile liquid absorbent wick,
It is an object of the present invention to provide a liquid absorbent wick for heat vaporization of an aromatic agent, which can maintain stable fragrance quality, fragrance strength and transpiration amount for a long period of time.
