Abstract:Osnovni namen raziskave je bil določiti veličine, ki so vzrok za porumenitev optično beljenjih pletenin. V raziskavi so bili analizirani že obstoječi madeži na pletenini, ki je bila tovarniško beljena in konfekcionirana (IR in UV/VIS spektrometrija). Nadaljnji namen raziskave je bil zasledovanje nastanka rumenih madežev pod vplivom različnih veličin: svetlobe, klimatskih pogojev, mazalnega olja, perkloetilena in spremne embalaže. Sprememba stopnje beline je bila zasledovana spektrofotometrično. Ugotovljeno je bilo, da je verjetni vzrok nastanka rumenih madežev tovarniško beljenih materialov mazalno olje ali njegovi razgradni produkti. Laboratorijska simulacija nastankov madežev, ki je bila izvajana sedem mesecev pod vplivom različnih veličin, ni povzročila nastanka karakterističnih rumenih madežev, prišlo pa je do padca stopnje beline. Od vseh analiziranih parametrov ima na spremembe stopnje beline največji vpliv mazalno olje pod vplivom svetlobe.

Title:Causes of optically bleached cotton knitwear yellowing
Abstract:The main purpose of the research was to determine the parameters responsible for the yellowing of optically bleached cotton knitwear. The stains on knitwear that had been previously factory-bleached and made were investigated by IR and UV/VIS spectroscopy. Another purpose was to monitor the formation of yellow stains under the influence of various parameters: light, weather conditions, lubricating oil, perchlorethylene and packing materials. The change of the degree of whiteness was monitored spectrophotometrically. It was found that the formation of yellow stains on factory bleached materials might be attributed to lubricating oil or its degradation products. During laboratory simulation of the stain formation performed for seven months (under different parameters) no characteristic yellow stains appeared, however, the degree of whiteness lowered. Lubricating oil under the effect of light had the greatest influence on the change of the degree of whiteness among all analyzed parameters.
