    摘要： The invention provides a process for preparing dyed, polypropylene-based fibers. Polypropylene having a Melt Flow Index of 45 or less is combined with an additive blend to provide the polypropylene-based polymer composition for forming into fibers. The additive blend is a terpolymer of ethylene, acrylic or methacrylic ester and maleic anhydride or glycidyl methacrylate combined with an amine-terminated polyamide, in weight ratio 3:1 to 1:1. Fatty acid monoglyceride may also be used in the polymer composition to further improve dyeability. The polypropylene-based fibers are readily dyeable by contacting the fibers with an aqueous dispersion of a disperse dye, to provide fibers with high color intensity (deep hues) and high dye substantivity and color fastness, without the need to employ temperatures in excess of the atmospheric pressure boiling point of the dye dispersion.

    摘要： Quaternary ammonium salts were incorporated into anthraquinone dyes via a stable linkage. The structure of the antimicrobial colorants were characterized by Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR) and UV-vis spectrometry. The dyes demonstrated excellent antimicrobial ability against both gram-negative and gram-positive bacteria in aqueous solution, as indicated by very low minimum inhibitory concentration (MIC). The colorants showed excellent stability in water under light, continuous heating as well as acidic and alkaline conditions.

    摘要： A method is provided for dyeing a non-cellulosic organic material with a dye, preferably a vat dye, comprising (a) treating the material with a dye in the presence of a reducing agent and an alkali and (b) oxidising the treated material produced in step (a) characterised in that the concentration of reducing agent used in step (a) is increased above that used for conventional vat dyeing such that the resultant dyed material has a lightfastness of 5 or more by BS 1006 B01 and B02 (1978) and/or has a washfastness or 5 or more by British Standard Test BS 1006 C06.C2 (1981). Preferably the step (a) is carried out in the presence of an alkali in concentration of at least 0.5 molar, more preferably 1 molar or more and most preferably 1 to 4 molar. The method provides vat dyed non-cellulosic organic materials having a reflectance of infrared light of wavelength 400 nm to 680 nm of less than 15%.

    摘要： A method of dyeing polypropylene fiber to create areas of different color on the fiber. A first dye solution containing a disperse dye and a dye-promoting agent is applied to substantially the entire surface of the fiber to cover the fiber with a first color. Thereafter, and while the fiber surface is still wet with the first dye solution, a second dye solution containing a disperse dye of a second color is applied only to selected discontinuous areas of the fiber. The second dye solution displaces the first dye solution in those areas of the fiber surface to which the second dye solution is applied. Then, the fiber is subjected to an elevated temperature high enough, and for a period of time sufficient, to fix the dyes in the fiber. Preferably, the second dye solution is more viscous than the first dye solution. After the dye fixation step, the fiber is scoured to remove excess dye. If desired, the second dye solution also contains a dye-promoting agent.
