Abstract

PROBLEM TO BE SOLVED: To make it possible to maintain aromatic quality, perfume intensity and transpiration rate stably over a long period of time by bonding the top or sliver of synthetic resin fibers with a thermoplastic resin in such a manner that specific porosity is attained and forming a liquid absorbent core material. SOLUTION: The liquid absorbent core material 20 for thermal transpiration of the aromatic is formed by bonding the top or sliver of the synthetic resin fibers of acrylic, etc., having about 1 to about 15 denier single fiber fineness with the thermoplastic resin, such as melamine. At this time, the porosity is set at 25 to 35% and the top or sliver is normally formed to a bar shape of about 3 to about 7mm in size and about 3 to 30mm in length. The upper end 22 of the liquid absorbent core material 20 for thermal transpiration of the aromatic is mounted in the opening formed in the central part of a heating means 11 by approximately aligning this end to the rear surface of the aperture and the lower end 21 thereof is immersed into an aromatic chemical AR.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a liquid absorbent core material for heating and fragrance heating, and more particularly, to a liquid absorbent core material for air freshener heating and evaporation capable of maintaining a stable fragrance and evaporation amount for a long period of time. It is about.

2. Description of the Related Art Conventionally, as a suction core material for volatilizing a drug including an aromatic agent at room temperature, as disclosed in JP-A-2-200135, a single yarn thickness of 5 to 20 denier is used. A sliver made of acrylic resin fiber is bonded and molded with melamine resin, and its porosity is 40% to 60%.
A non-heating type wicking core material for volatilization was used.

The above-mentioned conventional non-heated fragrance wicking core material for volatilization absorbs the chemical solution from its lower end, which is immersed in the fragrance chemical solution, to its upper end by capillary action and volatilizes it to the periphery. 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. On the other hand, the porosity is required to be 40% to 60% in order to suck up the fragrance liquid well under the non-heating condition and to sufficiently volatilize it. When the porosity of the wicking core material for non-heated fragrance for fragrance is 40% or less, the wicking amount of the fragrance liquid inevitably decreases in the non-heated state, and the fragrance effect itself deteriorates. there were.

On the other hand, a liquid absorbent core material for heating and vaporizing an insecticide as a heating type suction core material has been proposed in, for example, Japanese Patent Laid-Open No. 4-308501. This absorbent core material for heat vaporization of insecticide is
The top or sliver made of synthetic resin fiber such as acrylic, nylon, ester, etc. with a single yarn thickness of about 3 denier is bonded and molded with a thermosetting resin such as melamine, phenol, urea, etc., and its porosity is 12 % To 18%.

An insecticide drug solution using the above-mentioned absorbent core material for heating and evaporation of insecticide is, 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 of the pesticide heating evaporation liquid absorbent core material immersed in the pesticide chemical liquid to its upper end by capillary action, surrounds the vicinity of the upper end. About 140 due to the heating means provided
When heated to a temperature of ℃ or less, it was released to the periphery with an appropriate amount and duration of transpiration to exert an insecticidal effect.

[0006]

In order to continuously supply the fragrance to the surroundings, it is preferable to use a method of heating and evaporating. For that purpose, the fragrance is of good quality especially in terms of fragrance and fragrance strength. It has been requested. However, a conventional core material having a porosity of 12 to 18% has not been able to satisfy the requirement.

The present invention solves the above-mentioned problems of the conventional non-heated wicking wicking core for fragrance and liquid wicking core for heat evaporation, and maintains stable fragrance, perfume strength and transpiration amount for a long period of time. It is an object of the present invention to provide a liquid absorbent core material for heating and evaporating an aromatic agent.

[0008]

The object of the present invention is to:
A synthetic resin fiber top or sliver bonded and molded with a thermoplastic resin has a porosity of 25% to 35
%, Which is achieved by a liquid absorbent core material for fragrance heat evaporation.
