Vlna a jej\u00ed struktura<\/h3>\n

Vl\u00e1kna vlny jsou tvo\u0159ena proteinov\u00fdm komplexem keratinu. Tento keratin je citliv\u00fd na teplotu a mechanick\u00e9 nam\u00e1h\u00e1n\u00ed. P\u0159i pran\u00ed, i v chladn\u00e9 vod\u011b, se vl\u00e1kna vlny nap\u00ednaj\u00ed a potom se mohou srazit, pokud jsou vystavena teplu nebo mechanick\u00e9mu tlaku (nap\u0159. \u017ed\u00edm\u00e1n\u00ed v pra\u010dce). Struktura vlny je slo\u017eit\u00e1 a obsahuje \u0161upinky, kter\u00e9 se vz\u00e1jemn\u011b propl\u00e9taj\u00ed. Pran\u00ed v chladn\u00e9 vod\u011b tyto \u0161upinky sice m\u00e9n\u011b naru\u0161uje ne\u017e tepl\u00e1 voda, ale st\u00e1le existuje riziko jejich po\u0161kozen\u00ed a n\u00e1sledn\u00e9ho smr\u0161t\u011bn\u00ed.<\/p>\n

Vliv teploty vody<\/h3>\n

A\u010dkoliv chladn\u00e1 voda je pro vlnu \u0161etrn\u011bj\u0161\u00ed ne\u017e tepl\u00e1, neznamen\u00e1 to, \u017ee je zcela bez rizika. I chladn\u00e1 voda m\u016f\u017ee zp\u016fsobit zm\u011bny ve struktu\u0159e vlny, zejm\u00e9na pokud je kombinov\u00e1na s jin\u00fdmi faktory, jako je mechanick\u00e9 nam\u00e1h\u00e1n\u00ed. Optim\u00e1ln\u00ed teplota pro pran\u00ed vlny se pohybuje kolem 30\u00b0C. Libovoln\u00e1 vy\u0161\u0161\u00ed teplota zvy\u0161uje riziko sr\u00e1\u017een\u00ed.<\/p>\n

Agresivn\u00ed prac\u00ed prost\u0159edky mohou po\u0161kodit vl\u00e1kna vlny a zp\u016fsobit jejich smr\u0161t\u011bn\u00ed.
