DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber product obtained by attaching a bamboo vinegar solution having functions such as insect repellent, antibacterial and deodorizing to the surface of a fiber, and adding these functions and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, when imparting functions such as deodorization and antibacterial properties to various fiber products, there is a method of attaching various chemicals to the fibers in order to impart the functions to the fibers. The attachment method is
Mix the solid drug particles and the like with a binder such as an acrylic resin, apply the drug-mixed binder to the fiber,
It was to be cured. According to this method, the drug is firmly attached to the fiber and hardly drops even when subjected to a physical action such as washing.

[0003]

In the above prior art, solid drug particles can be adhered to fibers by a binder, but liquid medicine cannot be effectively adhered to fibers as they are. However, even if it soaked into the fiber, it easily fell off by washing. Further, if a liquid drug is directly mixed into the binder, there are problems such as a decrease in the adhesive strength of the binder and an insufficient effect of the drug.

In recent years, bamboo vinegar extracted from a smoke distillate (smoke liquor) when bamboo is made into charcoal has a high insect repellent effect, a bactericidal effect against putrefactive bacteria, a deodorant effect, and the like. It has been suggested that bamboo vinegar is used as an antibacterial agent and a deodorant.

[0005] The present invention has been made in view of the above-mentioned problems of the prior art, in which a bamboo vinegar solution is firmly adhered to fibers.
An object of the present invention is to provide a fiber product in which the effect of bamboo vinegar is sufficiently exerted for a long period of time and a method for producing the same.

[0006]

SUMMARY OF THE INVENTION The present invention is a fiber product in which a fine particle sustained-release carrier impregnated with a bamboo vinegar solution obtained from bamboo is attached to the fiber surface via a binder. This sustained-release carrier is formed of fine particles of a porous inorganic material such as silica and other ceramics, fine particles of a porous material made of a synthetic resin such as urethane resin, fine particles of a porous carbon such as bamboo charcoal and other activated carbon, and has a large surface area. , Pore volume.

Further, a bamboo vinegar solution obtained from bamboo is impregnated in a fine-particle sustained-release carrier, the sustained-release carrier is mixed with a binder, and a mixture of the sustained-release carrier and the binder is applied to fibers. This is a method for producing a fiber product in which a binder is cured.

In the textile product of the present invention, the bamboo vinegar is impregnated into a sustained-release carrier of fine particles and attached to the fiber with a binder. The effect of the vinegar is fully exhibited over a long period of time.

[0009]

Embodiments of the present invention will be described below. The textile product of this embodiment is made of a woven fabric, a knitted fabric such as a synthetic fiber fiber, a semi-synthetic fiber, a natural fiber, and the like, and a sustained-release carrier (microcapsule) 10 impregnated with a bamboo vinegar solution. It is attached to the surface of the fiber 14. The sustained-release carrier 10 is formed of fine particles of a porous inorganic material such as silica or other ceramics, fine particles of a porous material made of a synthetic resin such as a urethane resin, fine particles of a porous charcoal such as bamboo charcoal, or other activated carbon. Fine particles having a large surface area (300-900 m ² / g) and a fine pore volume (1.0-2.0 ml / g). Then, the liquid impregnated from the holes gradually evaporates and dissipates. As the binder 12, a polyurethane resin, an acrylic resin, a silicone resin, a polyester resin, or the like is used.

In the method for producing a fiber product of this embodiment, first, when bamboo is made into charcoal, the sustained-release carrier 10 is impregnated with a bamboo vinegar solution obtained from a smoke liquid which is a distillate of the smoke. Thereafter, the sustained release carrier 10 is mixed with the binder 12 and sufficiently stirred. Then, the binder 12 mixed with the sustained-release carrier 10 is attached to the surface of the fiber 14 as a product. The method of adhering the mixed solution of the sustained release carrier 10 and the binder 12 to the fiber 14 is, for a product, a padding method of dipping the mixed solution of the binder 12 and the sustained release carrier 10 as it is, or a spraying method for spraying the mixed solution. Done by law. In the case of fabric processing, it is performed by a coating method other than the padding method and the spray method. Then, after adhering the mixed solution of the sustained release carrier 10, the binder 12 is cured by drying at a predetermined temperature.

According to the fiber product of this embodiment, since the bamboo vinegar is impregnated in the sustained-release carrier 10, the bamboo vinegar is gradually released to the outside over time, so that the bamboo vinegar has an insect repellent effect and a bactericidal effect against putrefactive bacteria. The deodorizing effect is sufficiently exhibited for a long period of time. Since the sustained-release carrier 10 is firmly adhered to the surface of the fiber 14 by the binder 12, it does not easily fall off even when stimulated by washing or friction, and has excellent durability.
According to the bamboo vinegar solution, functional fiber processing having high insect repellent effect and the like and high safety is possible.

When functional particles having a deodorizing property such as bamboo charcoal are used as the sustained-release carrier 10, the deodorizing property and the like can be maintained even after the bamboo vinegar solution is diffused. it can.

In the fiber product of the present invention, after the binder 12 is cured, the fiber 14 is coated with an optical surface to remove the binder 12 outside the fiber product from the binder 12 covering the surface of the sustained release carrier 10. It may be set in a processing apparatus and the surface on which the binder 12 is attached may be irradiated with ultraviolet rays. An ultraviolet light source for this optical surface treatment apparatus uses a constant-pressure mercury lamp or the like, and has a wavelength of 184.9 nm and 253.7.
The irradiation time is 45 to 180 seconds at two wavelengths of nm.
In this case, the surface of the binder 12 is deteriorated by ultraviolet irradiation, the intermolecular force is weakened, and the binder 12 covering the sustained-release carrier 10 is in a state of being easily peeled. For this reason,
The surface of the sustained-release carrier 10 is easily exposed, and the bamboo vinegar is easily released, so that the effect of the bamboo vinegar acts more quickly and effectively.

The present invention is not limited to the bamboo vinegar solution, but can be used for function addition processing using other functional chemicals.

[0015]

According to the fiber product of the present invention, the sustained-release carrier having the bamboo vinegar solution is durably adhered to the fiber by the binder, and the effect of the bamboo vinegar solution is sufficiently exhibited for a long period of time. Things. As a result, it has high insect repellent effect, antibacterial effect against putrefactive bacteria, and deodorant effect, and is safe.
