A strand of spider silk is about 25 micrometers (0.00001 inches) in diameter. It is strong and dimensionally stable. Hummingbirds and other animals use spider silk for nest-building. Spider silk is currently used for crosshairs in optical instruments. Attempts have been made to produce fabric from spider silk, but it took an enormous number of spider webs and work to produce a fabric that was so sheer that it was of little use.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31418175"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31411593"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31344366"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9847879"> <skos:prefLabel xml:lang="ca">spider silk (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14085490"> <skos:prefLabel xml:lang="es">spider silk (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:40:59</dct:created>  </skos:Concept></rdf:RDF>
