Tightened beyond the standard

A profile may tighten a parameter, never loosen it. Imperium declares stricter limits than Grade TX-A requires.

ParameterStandardImperium
Residual shive (% m/m)≤ 3.0≤ 0.6
Fineness (dtex)6.1 – 12.06.1 – 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.
