General test

For general tests, we perform necessary tests according to the characteristics and use of the materials from a wide range of test items.

General test

Fabric test is to inspect and test the basic performance of the fabric. The type of testing is very diverse, but it is not necessary to carry out all the testing. The tests carried out are according to the characteristics and the use of the material.

Please refer to "Lists of test sample size (PDF)" for the sample sizes of the main fabric test.

Color Fastness

Color Fastness test carries out tests depending on the purpose inorder to check whether the fabric color does not change (discoloration) or does not stain other clothing (contamination).

Examples of test items

Light
Water
Perspiration
Washing
Rubbing
Dry cleaning
Light and perspiration
Chlorinated water
Nitrogen oxide (NOx gas)
Sublimation
Bleeding
Water spotting

Physical Performance

Abrasion strength (JIS L 1096 Martindale abrasion tester) — Abrasion strength
(JIS L 1096 Martindale abrasion tester)

Physical Performance test carries out tests for the strength of the fabric or, how easy pilling occurs, etc. Physical Performance test also has many testing’s according to the characteristics and the use of the material. For woven tests, there are tensile strength, tearing strength, slippage resistance, and for knit, there are bursting strength, etc. Also, depending on the materials, rubbing strength, pile retention, stretch and recovery, pilling, etc. are carried out.

Examples of test items

Tensile strength (Strip method, Grab method)
Tearing strength (Pendulum method, Single tongue method)
Bursting strength (Mullen method)
Slippage resistance (Seam slippage method, Yarn pull out method, Pin hooking method)
Pilling (ICI type method, Random tumble method, etc.)
Snag (Mace method, ICI type pilling method, Card clothing roller method)
Abrasion resistance (Universal type method (flat/ bending/ fold method), Scott type method, Taber type method, Martindale method, etc.)
Pile retention (A method, etc.)
Elongation recovery rate (Constant load method, Constant rate Elongation rate, etc.)
Seam strength (Grab method, Mullen method)

Dimensional change rate

Dry cleaning method (JIS L 1096, wash cylinder type washing device) — Dry cleaning method
(JIS L 1096, wash cylinder type washing device)

As the name suggests, dimensional change test measures the stretching and shrinking of the fabric from washing. The test is carried out by using an actual equipment of a dry cleaning, washing machine and press etc. test machine.

Examples of test items

Immersion method (A~D method)
Washer method (F-1~F-3 method)
Press method (H-1~H-4 method)
Commercial dry cleaning
Launderometer method (E method)
Electric washing machine method (G method, JIS L 0217)
Dry cleaning method (J-1, J-2 method)

Fiber mixture rate

Fiber identification (JIS L 1030, microscope testing)

This test is to identify the fiber for unknown material and confirm the claimed fiber mixture is carried out. We can also carry out resin identification for coating, lamination, etc.
