Uporaba tržnih detaširnih sredstev pri gospodinjskem pranju

Koščak, Špela (author), Kert, Mateja (mentor)

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.

• Title: The use of commercial spotting agents in household washing

Abstract

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
