How many clothing sizes does a stretch fabric save?

research/garment-sizestretch

How many sizes does a stretch fabric save? On a stylised synthetic bust/hip population, 10% usable stretch cuts the sizes needed for 80% fit from 6 to more than 8 down to 2 or 3; an idealised upper bound (preliminary).

What it found

Stylised and preliminary: follow-up to the size-set project on a synthetic bust and hip population (assumed means 95 and 100 cm, sd 8 cm, no survey data). A body fits a garment if it is at most 8 cm smaller and no more than stretch larger than the nominal size, in both measurements; the best k sizes are found exactly (integer program). Sizes needed to fit 80% fall from 6 to more than 8 with no stretch to 2–3 at 10% and 1 at 20%, and the loss on fresh people shrinks too. The stretch model is idealised: usable stretch is far below rated stretch, so these are upper bounds.

How much comfort can an infrared-transparent or gating textile buy, and which fabric properties matter?Fanger/ISO PMV and a two-node model extended with fabric infrared transmittance, emissivity and solar absorptance: indoors, transmittance 0→0.8 is worth ~2.4 °C of comfort at 28 °C; in sun, absorptance dominates. Stylised; assumed fabric properties, no reference for the optical extension.
How far is the repository's two-node thermal model from an open-source implementation of the Gagge model?Cross-checks garment-thermal's two-node model against pythermalcomfort over 108 conditions: core temperature within 0.25 °C, skin temperature mean 0.6 °C (up to 2.1 °C) apart; a comparison of implementations, not of people.
Which design choices explain the gap between the repository's two-node model and an open-source Gagge implementation?Switches nine design choices one at a time between garment-thermal's two-node model and pythermalcomfort's: variable skin mass fraction, convection coefficient and vasodilation gain explain most of the 0.58 °C skin-temperature gap; a comparison of implementations, not of people.
Do the fabric-optics conclusions of the thermal-comfort model survive a different two-node implementation?Adds garment-thermal's fabric optics (infrared transmittance, emissivity, solar absorptance) to the switchable two-node model and re-runs the comparisons under pythermalcomfort's choices: property rankings agree in all four scenarios, sizes within 3% at 28 °C but up to ~2× apart in cool air and in sun; a comparison of implementations, not of people.
Do the fabric-optics effects on thermal comfort change once the two-node model reaches steady state?The fabric-optics comparison of garment-twonodeoptics run to steady state instead of one hour: the cool-room disagreement between design choices mostly vanishes (stylised).
Do the closed and open bounds of an infrared-gating textile survive other two-node design choices and steady state?The closed-to-open bounds of an infrared-gating textile from garment-thermal hold under both two-node choice sets and at steady state: opening the gate cools skin by 0.20–0.25 C at 31 C and keeps it 1.4–1.5 C cooler at 16 C; stylised, preliminary.
