Declared process route
Tightened beyond the standard
A profile may tighten a parameter, never loosen it. Imperium declares stricter limits than Grade TX-A requires.
| Parameter | Standard | Imperium |
|---|---|---|
| Residual shive (% m/m) | ≤ 3.0 | ≤ 0.6 |
| Fineness (dtex) | 6.1 – 12.0 | 6.1 – 8.0 |
| Colour (Hunter L*, min) | ≥ 55 | ≥ 66 |
Handle / softness
Declarant enzymatic softening index, method on file
Compatible yarn counts
10s – 30s (see the separate Imperium Yarn profile)
Typical blend range
20 – 40% hemp with cotton or lyocell
HFGA-assessed
Verified under Clause 7 of the standard.
No PFAS
Total organic fluorine < 20 mg/kg.
No pesticides beyond EPA tolerance
QuEChERS panel; products lacking an EPA hemp label are not permitted.
Declarant claims
Imperium's own positions — outside the standard's scope, not assessed by HFGA.
95% less water than cotton
Declarant lifecycle assessment — water use is outside the standard's scope.
No microplastic shedding
Inherent to a cellulosic fiber — a finished-fabric property, not assessed at fiber stage.
No endocrine-disrupting chemicals
Declarant process declaration — Clause 7 tests PFAS, pesticides, formaldehyde, and heavy metals, not an endocrine panel.
Verification status
HFGA-TX-US-01 is at Draft status, so this profile is registered as a labelled pilot only and carries no conformity claim yet. There is no Lot Verification Record on file — a lot-level claim follows once the standard reaches Published status and a lot is verified.
Building to a standard you can check
The full profile and its evidence live on the public HFGA registry.
