摘要

The reflectance at 480 nm of tussah silk fabrics treated with chitosan after one-bath degumming and bleaching was 68.2%, which was the same as 71.2% for one-bath degumming and bleaching. The whiteness increased a little by oxidation or reduction bleaching. After treatment with fluorescent brightness agent of basic dye-type coumarin derivatives after one-bath degumming and bleaching, the reflectance of tussah silk fabrics in 5% o.w.f. of dye at 450 nm flight source: D65) was 81.2% of the same fabrics treated with chitosan and 86.9% of untreated tussah silk fabrics. These values were much more higher than when the fabrics were not treated with fluorescent brightening. The thickness and hardness of tussah silk fabrics treated with chitosan after one-bath degumming and bleaching increased more when bleached after degumming and chitosan treatment. The tussah silk fabrics treated with chitosan after one-bath degumming and bleaching were dyed by Orange II, Benzopurpurine 4B, Irgalan Red 2B, Kayalon Violet BB. Methylene Blue, Neolan Orange G. Alizarine Red S and Procion Orange H-GR. The dyeing affinities were increased by chitosan treatment, especially, increased for Benzopurpurine 4B and Orange II. The dyeing properties of tussah silk fabrics, which were treated with chitosan after one-bath degumming and bleaching, and dyed with orange II, was larger than when bleached after degumming and chitosan treatment. Benzopurpurine 4B and orange II,showed a large color difference in the case of silk treated with chitosan after one-bath degumming and bleaching. Benzopurpurine 4B had a great effect on hue, brightness and brilliance, and color saturation, and orange II on color saturation. These effects were caused by the large degree of the depth of shade.
