Colour Fastness Tests to Name Before a Mill Indent
Name colour-fastness expectations before a mill indent and before the sample 7–14 day clock starts. Colour fastness is a material’s colour resistance to fading or running. The main standardized families include washing fastness and light fastness (with rub fastness also commonly standardized); grades are often assessed with grey scales (Colour fastness, Wikipedia). The page’s references include the ISO 105 colour-fastness test series (for example ISO 105-C12 on industrial laundering).
Ask mills which named methods and grades apply to your cloth. Shi Yuan is a make factory: we confirm fabric before sample; we do not invent mill test certificates.
What should an indent / cloth brief ask for?
| Ask | Why it matters |
|---|---|
| Washing fastness method + grade | Protects against bleed/fade in care cycles |
| Light fastness method + grade | Protects against fade in display and wear |
| ISO 105 part codes if required | Names the test family (e.g. ISO 105 series) instead of “good fastness” |
| Grey-scale assessment | Aligns how grades are read between mill and buyer |
| Report before cut | Attach or summarize before sample confirmation |

Factory process link
Bulk from 50 follows the sealed sample and the written cloth brief. Construction (fused / half / full canvas) is separate from dye fastness. Production 14–21 days after sample approval.
"Confirm fabric—and any named fastness reports you require from the mill—before we start the 7–14 day sample. Bulk from 50 follows the sealed sample, not a vague “good colour” note." — Shi Yuan Suit Factory (statement built from published factory policy)
FAQ
What is colour fastness in textiles?
Colour fastness characterizes a material’s colour resistance to fading or running. Main standardized forms include washing fastness and light fastness; grey scales are used to assess grades.
What should buyers name before a mill indent for Shi Yuan programs?
Named washing and light fastness methods/grades (and ISO 105 part codes if you require them), plus cloth ID. Confirm fabric before the 7–14 day sample clock.
Does Shi Yuan issue ISO 105 certificates?
We are the make factory. Ask the mill for named colour-fastness reports; we confirm the fabric you approve before sample and match bulk from 50 to the sealed sample.
