FAQ

Frequently asked questions about this product:
What are the standard sizes for inside belt interfacing used in men's garments?
33 mm, 38 mm.
What kind of problem is kiratsuki?
It is the phenomenon of resin sparkling through the gaps in the weave of the face fabric.
Materials with a loose weave and dark-colored lightweight fabrics are especially noticeable, so using colored resin will resolve it.
What kind of problem is bleed-through?
A state where adhesive resin seeps through to the outer fabric, impairing the fabric’s hand.
As a solution, choose one with a smaller adhesive resin particle size.
What does the D (denier) in 20D or 30D mean?
Denier is a unit used for filament yarn (continuous filament)* and refers to the weight per 9,000 m. If 9,000 m weighs 1 g, that is 1 denier; if it weighs 50 g, that is 50 denier.
The higher the denier count, the thicker the yarn and the heavier the fabric.
What kind of problem is bubbling?
A condition where fine air bubbles appear to be trapped between the outer fabric and interlining. It occurs because the compatibility between the fabric and interlining is poor. It may be resolved by choosing an interlining with vertical and horizontal stretch.
What kind of problem is fading?
It is when the uneven texture of the resin pellets becomes clearly visible on the surface of the outer fabric. The solution is to choose interfacing with smaller resin dots.
What is the difference between single-dot and double-dot fusible interlining?
It is a difference in the adhesive coating method.
Single dot is made by solidifying fine powdered adhesive and transferring it in a dotted pattern onto the base fabric.
Because the adhesive is fine, it is less likely to bleed through thin materials and less likely to cause fading.
Double dot has a two-layer structure, with a gel-like adhesive forming the base and powdered adhesive layered on top of it.
It provides strong adhesion for a wide range of materials.
What is the difference between the whites such as KW, OW, W, and Y in fusible interlining colors?
The color notation varies by product number, but KW and W are fluorescent white, and Y and OW are off-white.
Fluorescent white is a whiter, purer white.
How should I choose interfacing?
The appropriate interlining varies depending on the face fabric material, thickness, and area of use, so we cannot give a single answer.
Please contact us via inquiries with the face fabric material, area of use (neckline, body, etc.), and desired hand feel.

If you can provide the face fabric, we can perform an adhesion test. Please request this from Interlining Adhesion Test.
By performing an adhesion test, you can find out in advance things like adhesive strength and changes in appearance.
Can interfacing be shipped rolled on a tube?
Basically, orders of 5 m or more will be shipped wound on a tube.
