About inspection


About fabric inspection


Fabric is the most important part when making apparel products.

Without quality, color, and fabric width, you won't be able to make the clothes you want.

In addition, if the fabric has many scratches or stains, the production quantity will decrease.

Factory inspections are commonplace in Japan, but unfortunately many factories in Southeast Asia do not do so properly.

We are investigating the differences in the colors of each fabric.(Photo below)


Even if the color is the same, if the color difference is severe, the color difference will be clearly visible between the sleeves and the body after sewing.

Fabrics sold in Southeast Asian markets are often not inspected.

When using fabrics from the Southeast Asian market, it is unavoidable because the production volume is small and the time required to complete the product is short.


There are many types, patterns, and colors of fabrics on the market, but there are many problems with inspection.


However, because trends change quickly, it is necessary to produce products in a short period of time, and the price is low, young Japanese casual manufacturers other than Shein are adopting it.











Our company inspects fabrics for the Southeast Asian market upon request.

However, there is a fee.

















About fabric quality inspection


This photo is a fabric quality inspection chart.

It is inspected and issued by a Japanese inspection company.

This is effective for fabrics that are dyed to order from scratch, but it is meaningless for fabrics that are already commercially available.



This table shows fabric values when dry and when washed, dry cleaned, sweated, and wet.

The highest number is 5. The average value is approximately 3.

Test for color transfer to other clothing or your body.

In Japan, a score of 3 or higher is considered passing.

Lightfastness is a value that measures the change in color due to sunlight.






This is a value obtained by examining the shrinkage rate and tearing of the fabric.


There is a fee for this test.
















Inspection of garment accessories

Garment accessories sold in Southeast Asian markets are rarely inspected.

The most important thing for clothing accessories such as zippers, metal buttons, and hooks is whether they are compatible with needle detection machines.


This is because if clothing accessories that are not compatible with needle inspection are attached to clothing, post-production inspection will not be possible.

We instruct overseas manufacturers to inspect clothing accessories using roller needle detectors or hand needle detectors.




The photo above shows clothing accessories being inspected using a roller needle inspection machine.

Similarly, completed clothing is also inspected by meter reading.


It's not a big deal, but

The needle detector uses permanent magnets that have a low reaction rate for non-ferrous metals such as fasteners.



Metal detectors use electromagnetic coils that are sensitive to all metals.









In addition to inspection at the factory, if requested, the finished product will be inspected at a local Japanese inspection factory before being shipped.

Japanese engineers are permanently stationed.




We are inspecting garment accessories.

The inspection standards are determined by the customer, but there are differences depending on the inspector.





This is the report of the first inspection.

If a product is inspected and is found to be defective, it is either returned to the garment factory for repair, or workers from the garment factory are called to the inspection factory's facilities to repair it.


This is a report on the results of repairing and inspecting defective products. Generally, about 15% of the production quantity is B products.



Approximately half of the products that are rated B at the inspection center are often determined to be non-defective after discussions with customers.

Depending on the customer's request, the luggage will be shipped by ship or plane.


In the case of sea freight, the voyage is approximately 30 days on the west coast of the United States and 40 days on the east coast.
