    • A method and an apparatus for determining diffusion parameters, concentration, size or flow behavior of particles in a sample, exciting light of a light source being directed into the sample, Raman scattered light being collected from an observed volume of the sample and being passed on to a spectrograph where it is resolved into spectral lines, the intensity of at least one spectral line being measured at least 10 times per second by means of one photodetector each, and the measured intensity values for the respective spectral line being used, via a fluctuation analysis, preferably an autocorrelation or a frequency analysis, to calculate diffusion parameters, concentration, size or flow behavior of the particle to which the spectral line in question can be assigned. With this method, it is also possible for signals of different spectral lines or bands, or signals of Raman scattered light, quasi-elastically scattered light and fluorescence light to be correlated with one another.

    • The invention seeks to provide a free-flowing formulation of one or more disperse dyes, with which packages can be dyed homogeneously by the HT process without filtering out of the dye, and which is suitable for the thermosol dyeing process. According to the invention such a formulation comprises one or more disperse dyes (a) enclosed in a matrix of one or more polymers (b) which are soluble, or colloidally soluble, both in water and in an organic solvent, in the form of a solid solution in a state of molecular dispersion or of extremely fine subdivision so that in an X-ray spectrum the dye appears amorphous.The formulations may contain additional assistants conventionally present when dyeing hydrophobic fibers. The formulations contain the disperse dye in an extremely fine state of subdivision. Because of the latter, the formulations give level package dyeings, without filtration of the dye, and very level dyeings when used by the thermofixing process.
    • 本发明寻求提供一种或多种分散染料的自由流动配方,通过该方法可以通过HT方法将包装均匀地染色,而不过滤出染料,并且适用于热溶胶染色方法。 根据本发明,这种制剂包含一种或多种分散染料(a),其包封在一种或多种聚合物(b)的基质中,所述聚合物(b)在水和有机溶剂中都是可溶于或胶体可溶的,形式为 在分子分散状态或极细细分的状态下的固溶体,使得在X射线光谱中,染料看起来是无定形的。 当染色疏水性纤维时,制剂可以含有通常存在的其它助剂。 制剂含有极细细分的分散染料。 由于后者,制剂在不过滤染料的情况下给予水平的包装染色,而当用热固定方法使用时,会产生非常高的染色。
