Among the products, underwear, nightwear, gloves, socks (excluding those for infants within 24 months of birth), underwear, gloves, wigs, false eyelashes, false beards,
Regarding adhesives used for shoe clasps, the elution limit of formaldehyde (formalin) is regulated by Ministry of Health and Welfare Ordinance No. 34 based on the Hazardous Substances Control Law. The method for measuring the degree of formaldehyde elution stipulated in this ministerial ordinance is a destructive test, in which the sample is made by cutting the fiber part of the textile material to be tested into small pieces, immersing it in purified water, extracting it, and making a test solution. Acetylacetone test solution is added to this to develop a color, and the absorbance is measured using a spectrophotometer to determine whether the product passes or fails to meet standards.This not only damages the product and makes it unusable, but also reduces the amount of time required for the test. However, it is extremely disadvantageous in terms of cost.

The product has no commercial value (in addition, testing takes a long time, and the same operations must be performed on standard-compliant products, so when testing a large number of products, it is not only economical but also rational. There was a problem in that it was not desirable at all from the point of view of labor saving.

である。以下その詳細を述べる。Means for Solving Problem C] In order to solve the above problem, the present invention brings a moistened paper disk into close contact with the area to be inspected of clothing, sandwiching both sides with non-water permeable plates and placing it at room temperature. After holding the paper disk for a certain period of time, remove the paper disk into a container with a lid, inject a certain amount of an alkaline test solution, a coloring test solution, and an oxidation test solution into it in order to develop a color on the paper disc.The degree of color development is evaluated and selected. The method adopted is to conduct tests based on official Ministry of Health and Welfare ordinances only for those that meet a certain standard. The details will be described below.
まず、この発明のペーパディスクは濾紙を２〜４枚程度
重ねた径５〜１０ｍ、取扱上好ましくは８＋ｅａの円板
状のもので市販品を流用しても構わない。First, the paper disc of the present invention is a disc-shaped disc made of about 2 to 4 filter papers stacked on top of each other and has a diameter of 5 to 10 m, preferably 8+ea for handling reasons, and a commercially available product may be used.

ーパディスクに移行させるのである。Next, moisten the above-mentioned paper disc with distilled water and apply it tightly to any part of the garment that you want to inspect, such as the outer fabric, lining, appliqué parts, etc., to prevent evaporation of moisture or shift of the paper disc. The clothing and paper disc are sandwiched between non-water-permeable plates (for example, synthetic resin plates that do not contain formalin and are preferably transparent) for a certain period of time (for example, 60 minutes) at room temperature (0 to 40°C).
Hold down. During this time, the garment remains in its original shape without any cutting or the like, allowing free formaldehyde in the garment to be transferred to the wet paper disk.

て酸化試液を加えて発色させる。After removing the wet paper disk that has been kept in close contact for a certain period of time and placing it in a container with a lid, inject 20 μm of a 5N-NaOH aqueous solution as an alkaline reagent, and then immediately inject the same amount (20 μm) of a coloring reagent. The tube is left to stand at room temperature for 15 minutes, for example, with the lid closed. Thereafter, the same amount of light, for example, a 0.75% 0.2N NaOH aqueous solution of potassium periodate (KIO3) is injected as an oxidation reagent. Here, the alkaline test solution is 4-amino-3
-Hydrazino-5-mercapto-1,2,4) lyazole (abbreviated as AHNT) is added to condense formaldehyde, and the amount of addition is determined by stirring the entire paper disk to capture and condense formaldehyde. Approximately 20 μl is recommended for complete progression.
In addition, AHMT, chromotropic acid, acetylacetone, chloroglucine, etc. can be listed as coloring agents, but AHMT is highly sensitive and can achieve the purpose with a small amount of use, and its reagent solution is widely used in environmental test methods. AHM used 70.5% 0.2N-HC1
Aqueous solutions are convenient. After waiting for the completion of condensate formation, an oxidation test solution is added to develop color.
その添加量は空気酸化で発色する部分もあるので適宜で

い。The amount to be added may be determined as appropriate since some parts may develop color due to air oxidation, but from the point of view of uniformly dispersing it throughout the paper disk, it is sufficient to use the same amount of 20 .mu.l as each of the above-mentioned test solutions as a standard.

省令に基づく正規の試験を行えば良い。A paper disk that has been subjected to such a color development treatment has a stronger color development and exhibits a deep reddish-purple color as the amount of formaldehyde eluted is large, so the degree of color development is judged by visual inspection based on a certain standard. As the judgment standard, we use the Japanese Industrial Standards (JIs) LO805r Gray Steel for Contamination, which is established as a judgment standard for visually judging the degree of staining on white cloth based on the dye fastness test results. , 5.4-5.4.3-4. from 5 with the least contamination (coloring) to 1 with the most contamination.
3.2-3.2.1-2.1 color chart (number) divided into 9 levels 2 or less (i.e. 2.1-2 and 1, the smaller the number on the color chart, the greater the color difference. It is only necessary to select those that correspond to the size (increasing in size) and conduct formal tests based on the Ordinance of the Ministry of Health and Welfare only on the selected ones.

施例の選別には誤りのないことがわかった。Example 1: First, a paper disc is moistened with distilled water, placed on the concave part of the acrylic plate for holding the paper disc, and brought into close contact with the surface of a diaper, diaper cover, rhombus, socks, hat, sweater, blouse, etc., and the opposing back side An acrylic flat plate was applied to the plate, the drawing board was held between clips, and the plate was kept at room temperature of 20°C for 60 minutes. The paper disk thus brought into close contact with the test site was transferred to the hole of the reaction plate as shown in the figure, and the lid was covered. The paper disks containing the 30 samples subjected to this procedure were placed into the 30 holes of the reaction plate, and the first solution was sequentially injected at 20 μl using a microsyringe and a dedicated tip, and then immediately after that, using another dedicated tip, Second
The solution was added in 20 pl portions, covered with a lid, and kept at room temperature for 15 minutes. After that, remove the lid and add 20 μl of the third liquid using another dedicated tip to complete the color reaction for 30 samples. The results were classified into those other than those (negative). When these operations were repeated and a total of 463 samples were examined, 12 were positive. Therefore, a formal formaldehyde elution test prescribed by Ministry of Health and Welfare Ordinance No. 34 was conducted on these 12 pieces. As a result, the absorbance exceeded the standard of 0.057
The absorbance of the solid body is 0.10SO, 09, 0, 07, 0゜05.0, 07.0.07 and 0.34, and the other 5 samples are 0.04.0.03.0.02 They were .0,04 and 0.03. As a precaution, we conducted a formal test to confirm the 451 samples that were negative.
No absorbance was detected at or below 0.01, indicating that the selection in this example was correct.

Since the conventional official testing method is destructive testing, not all products have been inspected, and we cannot guarantee that all the products we sell are safe and reliable. However, when there are 20,000 to 30,000 products to be tested at any given time, and there are daily and seasonal updates, it is difficult to use the regular test method of cutting up the specimen and using it as a sample. This means that you will be subject to restrictions.

言える。In response to this current situation, the detection method of the present invention does not require destroying the specimen (i.e., it is possible to perform 100% testing), and it is possible to make an effective determination of positive or negative in advance with a simple operation.
It is thought that safety will be greatly improved. If you carry a set of instruments, test solutions, standard color charts, etc. necessary for this detection method in a portable bag, you can easily test it even in a place like a product warehouse if the temperature is between 0 and 40 degrees Celsius. become able to do. Therefore, even if the subject of inspection is expanded not only to conventional products but also to new products or products of newly entered manufacturers, the method of this invention can sufficiently handle the problem, and therefore the significance of this invention is can be said to be extremely large.
