Document Summary
Determine what it is you are looking at. Most clothing falls into a moderate life expectancy. Long life expectancy want to perform in a good condition for a long time. To increase life expectancy, don"t use the textile frequently. Wear: broad term including physical forces in use and care. Aging: slow degradation from naturally occurring processes in the material over time. Takes place even when textiles are not in use, and is continuous. Degradation: encompasses aging but can also happen very quickly if the textile is exposed to harmful conditions. Change of hand; sti ness or loss of body. Loss of performance; ie. loss of water repellency. Colour change; fading or discolouration (general or localized) Identi cation - fabric structure, yarn structure, bre, nishes. Questions to ask to help understand causes of degradation. Describe - visual and tactile details are recorded. Documentation is an important part of textile analysis. Detection limit: varying degrees of noise inhibit identi cation.
