Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning identification tag indicating the owner's name and identification number in a laundry shop or laundry factory for identifying the owner of clothes such as underwear, shirts, and clothes.

[0002]

2. Description of the Related Art A conventional identification tag is formed by cutting colored wash-resistant paper into an elongated strip. To attach the tag to clothing, the tag is passed through a button hole of the clothing and folded in two. They were stapled together.

[0003]

However, a stapler is liable to cause an accident to damage clothes, and the work of attaching identification tags to many clothes by using a stapler is very troublesome and requires a great deal of labor. In addition, there is a risk of causing occupational diseases such as tenosynovitis. Also, when removing the identification tag from the cleaned clothing, it is difficult to tear it off by hand due to the strength of the paper wash,
Usually, the stapler needle was removed or the identification tag was cut with scissors, but this was also troublesome.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide an identification tag which can be securely fixed to clothing without damaging the clothing and which does not require a stapling work and therefore does not cause occupational diseases. To provide.

[0005]

SUMMARY OF THE INVENTION A cleaning identification tag according to the present invention comprises nylon 6, nylon 8, nylon 11 and / or nylon 1 on at least one side of a paper wash.
2 homopolymer or copolymer and paraoxybenzoic acid-2
-A heat seal layer comprising an adhesive composition containing -ethylhexyl.

The content of 2-ethylhexyl paraoxybenzoate is preferably 5 to 35 parts by weight per 100 parts by weight of the adhesive composition.

[0007] Before forming the heat seal layer, it is also preferred that at least one side of the paper washes is coated with a reactive urethane resin to undercoat.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The identification tag is easily adhered by heat sealing, and is detached from the clothing as it is until the last step of the cleaning operation without being affected by cleaning chemicals, laundry soap water, rinsing water, etc. Need to be nothing. That is, an adhesive layer made of a resin having heat sealability without being dissolved in water or hot water and a hydrocarbon-based or chlorine-based solvent used for general dry cleaning must be formed on at least one surface of the paper-washing paper. No.

As resins having such properties, there are nylon 6, nylon 8, nylon 11, nylon 12, and the like. In order to form such a resin heat-sealable layer on paper, it is easy to dissolve in a solvent, or it has the property of melting to a liquid or viscous liquid by heating to the melting point, and After coating, a resin that can be applied to paper-washing resistance is preferred.

In addition, since these resins are usually provided in very fine powder, for example, when two different nylon resins are used, a low molecular weight nylon resin is heated and dissolved in a solvent to form a solution. Alternatively, a nylon resin or a high molecular weight nylon resin which is hardly dissolved in methyl alcohol may be dispersed in this solution as powder. Examples of the nylon resin that is difficult to dissolve in methyl alcohol include a homopolymer of nylon 12 and a copolymer of nylon 11 and nylon 12, and a specific example thereof is nylon 12 manufactured by Rilsan.

Among the above resins, nylon 6, a homopolymer of nylon 8, nylon 11, and nylon 12 obtained by modifying nylon 6 with methyl alcohol and formaldehyde;
Alternatively, their copolymers and copolymers with carboxylic acids such as maleic acid have the property of dissolving in lower alcohols, and exhibit remarkable solubility especially in lower alcohols mixed with a small amount of calcium chloride.

As the lower alcohol, methyl alcohol, ethyl alcohol and isopropyl alcohol can be used. Among them, methyl alcohol is preferred because it has a high solubility and is compatible with water.

[0013] However, the above nylon resin is poor in flexibility if it is applied to at least one side of the paper-washing paper as it is,
In addition, the temperature required for heat sealing also becomes high, and the heat at the time of heat sealing may damage clothing.

Therefore, in the present invention, by mixing 2-ethylhexyl paraoxybenzoate (hereinafter referred to as POBO) as a plasticizer with a nylon resin, the flexibility of the resin is increased, and the temperature at the time of heat sealing is reduced to 110. ~ 1
Lowers to 30 ° C. In the present invention, the addition of POBO is indispensable, and when not added, the heat sealing temperature becomes 180 ° C. or higher.

The amount of POBO added is 5 to 35 parts by weight, preferably 10 to 25 parts by weight, more preferably 10 to 2 parts by weight, per 100 parts by weight of the adhesive composition.
0 parts by weight. If this addition amount is less than 5 parts by weight,
If the softening effect of the resin is poor, and if it is more than 35 parts by weight, the melting point of the resin is too low, and the identification tag may be peeled off from the adhesive portion at a high temperature in summer.

By mixing POBO with nylon resin, there is no change in flexibility throughout the year, and as described above, the commercial value and workability can be significantly improved by lowering the heat sealing temperature.

A liquid obtained by dissolving a composition containing a nylon resin and a plasticizer in alcohol is a transparent viscous liquid when heated, but becomes gel-like as it cools and becomes cloudy at normal temperature. This liquid solidifies in the winter, so when using it, heat it until it becomes a transparent liquid. As a method of applying a composition containing a nylon resin and a plasticizer to at least one surface of the paper wash, a roll coater, gravure,
A general coating machine such as a doctor coater can be used. It is preferable that the roll and the liquid tank can be heated. The thickness of the heat sealing layer is preferably 2
10 to 10 g / m ² , more preferably 3 to 8 g / m ² .

As the undercoat agent, a urethane resin-based resin, that is, a urethane resin or a resin based thereon is preferable. Since the reactive urethane resin-based undercoat agent has particularly high reactivity, when an organic amine is used as a curing agent, it hardens and becomes insoluble in water and a solvent, and does not dissolve at all in a solvent or other liquid used for cleaning. In addition, by applying an undercoat to a highly permeable paper wash, the heat seal layer can be made thinner and the adhesive effect can be significantly improved. As the undercoat agent, a casein-based resin, that is, casein or a resin based thereon is also preferable. The layer thickness of the undercoat is preferably 2
10 to 10 g / m ² , more preferably 3 to 8 g / m ² .

The paper-resistant paper on which the heat-sealing layer is to be formed may be one conventionally used.

[0020]

The present invention will be described below in more detail with reference to examples.

Example 1 CM4000 (Nylon 11 copolymer type) 20 parts by weight manufactured by Toray Co., Ltd. POBO 3 parts by weight manufactured by Yoshitomi Fine Chemical Co., Ltd. 77 parts by weight of methanol When these mixtures are heated with stirring, solids gradually dissolve and become transparent. A viscous liquid was obtained. Using a No. 12 bar coater, this was coated on one side of a paper-wash-resistant paper having a length of 170 mm, a width of 100 mm, and a thickness of 0.2 mm, and dried to form a heat seal layer having a dry solid content of about 5 g / m ^2. Formed. This wash-resistant paper was cut into a width of 10 mm and a length of 85 mm to produce a strip-shaped identification tag.

The discrimination tag was folded in two so that the coated surfaces were aligned, and the folded body was pressed from the non-adhered surface with an iron at 130 ° C. to be heat-sealed and completely adhered. This was immersed in 70 ° C. warm water, room temperature water, perchlorethylene, and ligroin, respectively, and allowed to stand for one day.
The bonding strength was so strong that the bonded portion did not peel off at all.

If this is applied directly to the wash-resistant paper, it will seep into the paper. Therefore, an alcohol aqueous solution of casein is applied in advance to one side of the same wash-resistant paper as in Example 1 and dried, and the dry solid content is about 6 g / m ² . An undercoat having a layer thickness was formed. In this case, ammonia was used as a casein dissolving agent. Since ammonia evaporates during drying, casein does not dissolve in water after drying. On the undercoat thus formed, the above nylon resin solution was applied with a No. 12 bar coater and dried to form a heat seal layer having a dry solid content of about 5 g / m ² . A band-shaped identification tag was produced from the washed paper in the same manner as in Example 1.

When the adhesion of the obtained identification tag was examined in the same manner as in Example 1, the adhesion was extremely good.

Example 3 Toresin MF-30 (Nylon 8) Teikoku Chemical Sangyo Co., Ltd. 20 parts by weight Juurezin (Nylon 11 type) Lead City Co., Ltd. 10 parts by weight POBO Yoshitomi Fine Chemical Co., Ltd. 5 parts by weight Methanol 62 parts by weight Water 3 parts by weight Part When these mixtures were heated in the same manner as in Example 1, a slightly viscous transparent solution was obtained. To 100 parts by weight of this liquid, 20 parts by weight of a powder of nylon 12 ("Rilsan" manufactured by Elf-Atochem) was added, and the liquid was slowly stirred to obtain a white liquid in which the powder was uniformly dispersed. Example 1

A layer was obtained. A band-shaped identification tag was produced from the washed paper in the same manner as in Example 1.

When the identification tag was folded in two so that the application surfaces were aligned, and the folded body was pressed with an iron at 150 ° C. from the non-adhesive state, it was heat-sealed and completely adhered. When this was subjected to an adhesive test under the same conditions as in Example 1, the adhesive strength was high and the bonded portion did not peel off at all.

Example 4 A 20% isopropyl alcohol solution of an alcohol-soluble reactive urethane resin ("Takeda Urethane 369" manufactured by Takeda Pharmaceutical Co., Ltd.) was prepared, and a small amount of trimethylamine was added as a curing agent to the undercoating agent. I got This was coated on one side of the same paper-washing paper as that of Example 1 with a roll coater and dried to form an undercoat having a dry solid content of about 6 g / m ² .

Next, a mixture of the same nylon resin composition as used in Example 1, that is, CM4000 (nylon 11 copolymer type), 20 parts by weight, manufactured by Toray Industries, Inc. POBO, 3 parts by weight, manufactured by Yoshitomi Fine Chemical Co., Ltd., 77 parts by weight of methanol was used. When heated with stirring, the solid content was gradually dissolved to obtain a transparent viscous liquid. The temperature of this solution is about 40 ° C.
Was applied on the above-mentioned anchor coat with a roll coater and dried to form a heat seal layer having a dry solid content of about 5 g / m ² . A band-shaped identification tag was produced from the washed paper in the same manner as in Example 1.

When the adhesiveness of the obtained identification tag was examined in the same manner as in Example 1, extremely good adhesiveness was shown because the heat sealant did not penetrate into the paper.
