20.500.12556/RUL-110235 Uporaba tržnih detaširnih sredstev pri gospodinjskem pranju The use of commercial spotting agents in household washing V diplomskem delu je bil preučevan vpliv tržnih detaširnih sredstev na odstranjevanje različnih umazanij z bombažne, poliestrske in volnene tkanine pri gospodinjskem pranju. V raziskavi so bile uporabljene štiri različne umazanije, ki so v gospodinjstvih pogosto prisotne, in sicer borovnica, kečap, trava in rdeče vino. Uporabljeni sta bili dve tržni znamki detaširnih sredstev, in sicer Texil Detachant (D) in Dr. Beckmann (B). Pranje je bilo izvedeno na več načinov v skladu s standardom SIST EN ISO 105:C06 v napravi GyroWash pri 40 °C. Učinek pranja je bil spektrofotometrično ovrednoten z izračunom barvne razlike med vzorci pred izvedenim pranjem in po njem. Barvna razlika je bila izračunana z uporabo barvnega prostora CIELAB. Rezultati raziskave so pokazali, da je učinkovitost pranja pogojena z načinom pranja, vrsto in sestavo umazanije in surovinsko sestavo tekstilije. Detaširna sredstva B, v kombinaciji s pralnim sredstvom ali brez njega, so izboljšala odstranjevanje preučevanih umazanij s tkanin različnih surovinskih sestav v primerjavi z detaširnimi sredstvi D, kar smo pripisali sestavi detaširnih sredstev. In diploma thesis the influence of commercial spotting agents on removal of different soils from cotton, polyester and wool fabric in household washing was studied. Four different soils were used in the research, namely blueberry, ketchup, grass and red wine, which are very common household soils. Two commercial brands of spotting agents were used: Texil Detachant (D) and Dr. Beckmann (B). The washing of soiled fabrics was performed in accordance to SIST EN ISO 105:C06 standard in GyroWash apparatus at 40 °C. The washing efficiency was evaluated spectrophotometrically by determining of the colour difference between unwashed and washed soiled fabric using CIELAB colour space. The results showed that the washing efficiency was strongly dependent on the washing mode, type and composition of the soil, and the fabric composition. The spotting agents B alone or in combination with washing agent were more efficient in removing the studied soils from fabrics of different composition in comparison with the spotting agents D, which was attributed to the spotting agents’ composition bombaž poliester volna umazanija barvna razlika detaširna sredstva. cotton polyester wool soil colour difference spotting agent. true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-09-13 07:45:17 2019-09-13 07:45:19 2022-08-22 03:42:31 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 69840 4404.pdf 4404.pdf 1 76C56838B284209C767FDA17C9641848 ab055a642e7940be5eda3a12a4df18a6047c6658e438b8a4616f07cb34f54610 11f624b1-a1b7-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=121883 Naravoslovnotehniška fakulteta 0 0 0
