Abstract

PURPOSE:To facilitate the easy and sure mounting of the cleaning tag to clothing and to perfectly prevent the removal during cleaning by forming a two-pack crosslinking type acrylate tacky adhesive layer on a sealing coat having solvent resistance. CONSTITUTION:The sealing coat having the solvent resistance is applied on at least one surface of a band-shaped base material consisting of washing resistant paper and the two-pack crosslinking type acrylate tacky adhesive layer is formed on this sealing coat. Namely, the tacky adhesive layer provided on this sealing coat consists of the two-pack crosslinking type acrylate tacky adhesive. Various kinds of hardeners of an isocyanate system, melamine system, epoxy system, etc., are usable according to the functional groups introduced into the polymer of the chief material of the acrylate system. The mounting of the tag to the clothing is extremely facilitated by the pressure-sensitive adhesion of the ends to each other. The removal of the tag from the clothing during cleaning is completely prevented regardless of the kinds of cleaning systems.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cleaning tag that is attached to clothing to be cleaned in the cleaning industry and used to identify the person who has taken care of the clothing.

(Conventional technology) In general, in the cleaning industry, a large number of clothes are entrusted to us by a large number of customers, so in order to avoid confusion or obscurity of the owner, the reception of each garment is carried out from the time it is received until the item is handed over after cleaning. It is necessary to be able to consistently identify the depositor.

Therefore, conventional cleaning tags are made of wash-resistant paper strips on which an identification number can be printed or a name can be written, and these are passed through clothing buttonholes, collar hangers, belt loops, etc., and both ends are stapled. Fastening methods are widely used. It has also been proposed to apply hot melt adhesive to a part of a similar strip and fasten both ends using a heat press (Utility Model Application No. 56-150980, No. 5).
7-22781 etc.).

(Problems to be Solved by the Invention) However, with the conventional cleaning tags that are fastened with staples, the fabric is easily damaged by contact with the staples during cleaning, and depending on the fastening position and the condition of the staples, cleaning There were many cases where it would come loose from clothing.

On the other hand, cleaning tags using hot melt adhesive mentioned above use adhesive that can withstand the heat during drying, so
In addition to the high cost of materials and processing due to adhesive coating, the department needed to prepare special heat press equipment to receive laundry, so it was less practical than economical. .

In view of the above-mentioned circumstances, an object of the present invention is to provide a cleaning tag that can be easily and reliably attached to clothing, can completely prevent it from coming off during cleaning, and can be manufactured at low cost.

(Means for Solving the Problems) As a means for achieving the above object, the cleaning tag of the present invention includes a strip-shaped base material made of wash-resistant paper, at least one side of which is coated with a solvent-resistant sealing coat. It employs a structure in which a two-component cross-linked acrylic acid lister adhesive layer is formed on the coat.

(Detailed Structure and Effects of the Invention) The cleaning tag of the present invention utilizes the adhesive force of the adhesive to attach the ends to each other instead of the conventional general-purpose stapler or the conventionally proposed hot melt adhesive. As in the past, it is attached in a ring shape to buttonholes, collar hangers, belt loops, etc. of clothing, and is used for cleaning together with clothing.

By the way, adhesive fastening means are widely used for various labels, tapes, sheets, etc., but in the case of cleaning tags, they are violently agitated together with the clothes in the cleaning liquid and are subjected to strong shocks and friction, and are also difficult to clean. The liquid itself has completely different properties depending on the cleaning method, such as chlorinated hydrocarbon solvents and fluorinated solvents such as trichloroethane, perchloroethane, trichlorethylene, and perchlorethylene in dry methods, and alkaline aqueous solutions in laundry methods. Therefore, there are severe restrictions on the application of this method. In fact, in a tag structure in which an adhesive layer is simply provided on a strip-shaped base material, a practical adhesive that can withstand the harsh usage conditions described above has not been found, and in most cases, plasticization with a cleaning liquid is required. The cohesive force and adhesive force of the adhesive layer decreases due to the action, dissolution, and heat, resulting in a high rate of detachment of the cleaning tag from the clothing due to detachment of the attached portion.

However, in the cleaning tag of the present invention, a sealing coat is applied to the strip-shaped base material made of wash-resistant paper, and an adhesive layer is formed on the sealing coat, so that the adhesive is not applied from the base material side in the fixed state. The cleaning liquid is prevented from penetrating into the adhesive layer, and the adhesive layer contacts the cleaning liquid only at its periphery, so the plasticizing and dissolving effects do not extend to the inside, and separation of the adhesive layer is avoided. Ru.

However, even if a sealing coat is applied as described above, it is necessary to use a two-component curing acrylic ester adhesive for the adhesive layer formed on it. If other adhesives such as liquid-based acrylic ester adhesives are used, separation of the attached portion cannot be reliably prevented.

Note that for the purpose of preventing the cleaning liquid from permeating from the base material side, it is possible to use a synthetic resin film such as a polyester film as the base material. However, with such synthetic resin films, printed numbering, symbols, written names, etc. tend to disappear or become unclear during cleaning, so it is especially important to protect printed barcodes when performing customer management using barcodes. This necessitates an overcoat, which increases costs, and also has the drawback that the overcoat can cause misalignment of the barcode, which can easily lead to reading errors and defects.

The wash-resistant paper used as the strip-shaped base material is generally impregnated with resin such as melamine resin at the papermaking stage to impart solvent resistance and water resistance, and any commercially available wash-resistant paper can be used. be.

The coating agent used for the sealing coat may be one that has excellent solvent resistance and is not attacked by cleaning liquids, and both emulsion and solution types can be used. (line) Those containing a resin component whose solvent resistance is increased by self-crosslinking by irradiation or crosslinking by a crosslinking agent are preferable. Further, as the coating method, in addition to a method of coating the surface of wash-resistant paper using a coating device on a boat, a dipping method of immersing the wash-resistant paper in a coating liquid can also be adopted.

The adhesive layer provided on the sealing coat is made of a two-component cross-linked acrylic ester adhesive as described above, and isocyanate is added depending on the functional group introduced into the polymer of the acrylic ester base material. Various hardening agents can be used, such as hardeners, melamine-based, epoxy-based, etc. Such an adhesive is applied to a thickness of about 20 to 200 μm (dry equivalent) on the sealing coat of wash-resistant paper using a coating device such as a barcoke. Since the cleaning tag is attached to clothing in the form of a ring with both ends fixed, this adhesive layer may be provided at one end or both ends of the strip-shaped base material. Further, a release paper is attached to the surface of the formed adhesive layer in a pre-use state.

Cleaning tags are usually manufactured by applying a sealing coat and adhesive to a large area or wide wash-resistant paper base paper, pasting this onto release paper, and then slitting the base material into a strip that will serve as a cleaning tag. . Preferably, an identification symbol such as an identification number or a bar code is printed and displayed on the back side of the base material on which the adhesive layer is not provided, before or after the sealing coat.

(Example) After applying a filler coat to one side of wash-resistant paper (manufactured by Shikoku Paper Co., Ltd.), a barcode was printed and displayed on the reflective side, and then a two-component cross-linked acrylic was applied on the filler coat. A resin adhesive layer was formed. Then, after pasting polylamigracine paper as a release paper on the surface of this adhesive layer, wash-resistant paper was
