What each input means

Garment age (years)
Approximate age of the garment in years.
Fiber content
0=Cotton/linen, 1=Silk, 2=Wool, 3=Early synthetic (rayon/acetate), 4=Mixed/unknown.
Current condition (1-5)
1=Poor (tears, heavy staining, brittleness), 3=Fair (some wear, minor issues), 5=Excellent (like new).
Has embellishments
0=No, 1=Yes (beading, metallic thread, sequins, applique, etc.).
Storage humidity (%RH)
Relative humidity in the storage environment. Ideal is 45-55% RH.

What each result means

Fragility score (0-10)
Overall textile fragility: 0-2=Robust, 3-5=Moderate care needed, 6-8=Fragile, 9-10=Extremely fragile.
Cleaning method (0-4)
0=Standard wash, 1=Gentle hand wash, 2=Spot clean only, 3=Professional conservator, 4=Do not clean.
Max water temp (°C)
Maximum safe water temperature for any cleaning. 0 means no water contact.
Storage quality (0-100)
How suitable your current storage humidity is for preservation.
Remaining display life (years)
Estimated years before further significant degradation in current conditions.
Conservation cost ($)
Estimated cost for professional textile conservation treatment.
Acid-free tissue sheets
Number of acid-free tissue paper sheets for proper archival storage.
Insurance priority (0-100)
How strongly we recommend getting the garment appraised and insured.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Garment age (years) = 40, Fiber content = 0, Current condition (1-5) = 3, Has embellishments = 0 = 5 input(s) provided
  2. Calculate Fragility score
    Fragility score
    3 = 3
  3. Calculate Cleaning method
    Cleaning method
    1 = 1
  4. Calculate Max water temp
    Max water temp
    20 = 20
