“…However, they did find that yellowing was produced by heating in vacuo an oxidized ester that was initially colorless and that yellowing was inhibited by the addition of short-chain aldehydes possessing -CH 2 -CHO groups. Franks and Roberts (97) confirmed the conclusions reached, namely, that colorless precursors are formed by an oxidative mechanism and that yellowing is produced by subsequent polymerization and condensation reactions of the precursors with other active species present in the mixture. The latter reactions could be modified by the presence of short-chain aldehydes that, on condensing with the precursors, gave rise to colorless compounds.…”

“…These reactions will result in bond formation between the colored oxidation products of oily soil and fiber substrates, causing difficulty in soil and color removal. In a study on oxidative discoloration of ethyl linoleate on a cotton substrate, Franks and Roberts (97) showed that a polar substrate may affect not only the rate of the various reactions involved but also the secondary decomposition products formed. They proposed that the cellulosic hydroxyl groups of cotton fiber can react with some colored oxidation products, thus insolubilizing the latter.…”

Literature covering the problems of oily soil aging on textile materials is reviewed. Difficulty of soil removal and discoloration of oily soiled fabrics were the main problems of aged oily soil reported by researchers. Yellowing of fabrics is attributed mainly to residual oily soils although there are other causes. Oxidation of unsaturated oils was suggested as the cause of problems related to aging of oily soils; thus, the autoxidation mechanisms of unsaturated lipids are an important part of this review. The effects of aging on oily soil removal are attributed to this oxidation of unsaturated oils, wicking of oils into small capillaries within the yarn structure, and possible chemical linkages of aged oils with fibers. Thus, included in this review are studies on the interactions between lipid oxidation products and proteins that suggest interaction between aged oily soils and fiber substrates. JSD 1, 407-418 (1998).

“…This yellowing, which was observed approximately 500 hr after the initial soiling, may be due to a condensation reaction of autoxidized products with the cotton. Franks and Roberts [4] observed the greatest ,changes in yellowness after 200 hr at 22°C. However, their samples were not washed dur-ing this time, but were kept in tubes submerged in a constant temperature bath.…”

“…The mechanism for the autoxidation of unsaturated fats begins with the formation of hydrol5eroxides which decay rapidly [11]. Franks and Roberts [4] J used reflectance spectrophotometry to study the oxidative discoloration of ethyl linoleate on a cotton substrate and in the bulk phase. Significantly greater yellowing took place on cotton than occurred in the bulk phase and at a faster rate, indicating that the hydroxyl groups of cellulose were involved in reactions leading to discoloration.…”

A double-label radioactive tracer analysis was developed to determine the comparative retention of representative sebum components on cotton fabric after repeated soiling and laundering and to determine whether the presence or absence of clay significantly affected the retention of the fats. Retention was related to chain length, polarity, unsaturation, and presence of clay.The yellowness of cotton soiled with pairs of fats was measured in the presence and absence of clay. Clay contributed significantly to the yellow color. When fat alone was present, there was no significant increase in yellowing until after the fifth wash for oleic acid and triolein. An interaction between the fats and clay caused additional yellowing which was possibly due to greater uptake of clay by entrapment in a fatty matrix and/or to catalysis of oxidation reactions of unsaturated fats by metal ions present in kaolinite clay. ' I ABSTRACT Tumble-drying techniques similar to those which might be encountered in home laundering are investigated. The effects of fabric dimensions and aesthetic softness and limpness are studied, and a tentative explanation of the aesthetic changes in terms of observed physical differences is offered.
