Part 6: Formulation Effects of the Third Constituent of Anionic Surfactants or Protease Blended with the Nonionic Surfactants or Sequestering Agents on Detergency of Fabrics Artificially SoiledMasako Sato, Takako Matsuo, Motoi Minagawa1986 Volume 27 Issue 4 Pages 170-175

JOURNAL FREE ACCESSTo improve the quality of phosphate-free detergents, formulation effects of the third constituent (DBS, AOS or protease) blended with the nonionic surfactant (APE) and sequestering agent (SPA) were studied by using the artificially soiled fabrics (mixed with protein, mud, carbon black and synthetic sebum) .
1) In the DBS or AOS system, it was found that the three-component formulation has a little effect not only on protein soils also on particle soils.
2) In other protease systems, the soil removal efficiency of the protein and particles was significantly improved by the soil release behavior of the complex composed of protein and particles as well as by the interaction of three components.
3) To improve the quality of the detergent, it was expected that the combination of the various compounds having different detergency was required.View full abstractDownload PDF (716K) -
Part 2: On the Liberation of WaterShigeko Nakanishi, Mieko Yamakado1986 Volume 27 Issue 4 Pages 176-182

JOURNAL FREE ACCESSIn the previous report, mutual reactions of resin monomers and reactions between resin and cellulose molecules observed through formaldehyde liberation were studied during the thermal treatment under various conditions. The results were discussed in comparison with those obtained from the torsional rigidity determined by the dynamic viscoelasticity.
It has been found so far that the thermosetting progress and the chemical reaction proceeded keeping parallel pace, but activation energies obtained chemically from the liberation of formaldehyde were higher than those obtained physically from the dynamic viscoelasticity. This was probably due to neglect of the reaction in which water liberated.
In this study, therefore, water liberated with proceeding of the above reaction was taken into consideration. After that an attempt was made to consider the contribution of activation energies from both formaldehyde and water in proportion to the molar ratio of the two products.
The apparent activation energy for each resin finished fabric thus obtained remarkably coincides with that obtained from the torsional rigidity. From these facts, it was made clear that the result observed from the physical aspect agreed well with that obtained from the chemical reaction when all the possible products were taken into consideration.View full abstractDownload PDF (927K)
