発明の名称 (英語) DYED POLYPROPYLENE FIBER STRUCTURE, GARMENT USING SAME, AND ANTHRAQUINONE COMPOUND NEW コモンズ 新技術説明会
発明の概要(英語) A dyed polypropylene fiber structure according to one embodiment of the present invention is dyed with a blue dye that is represented by general formula (1) (wherein R1 represents a linear or branched alkyl group having 4-14 carbon atoms).
従来技術、競合技術の概要(英語) BACKGROUND ART
A polypropylene resin is an addition polymerization of propylene, a crystalline thermoplastic resin. Refinery waste gas at the time of this polypropylene resin as a raw material for a propylene and inexpensive and, as the float on water and reduce the weight of low density (0.90-0.92g/cm3), water absorption, there is little hygroscopic quick-drying (official moisture regain 0.0%) in order. Further, the polypropylene resin chemical resistance, abrasion resistance, bending resistance, antistatic property, a large number of excellent characteristics, having a nonlinear characteristic (non-patent document 1, reference 2).
A branched hydrocarbon polymer such as polypropylene and a simple, but that it is a methyl group and pendant groups, the chemical reaction of the dye does not have a functional group that is effective. In addition, a relatively dense crystalline polypropylene, very high hydrophobicity, the water swollen most not. For these reasons, conventional staining techniques and coloring of the polypropylene has been extremely difficult.
In this way is difficult to be stained as polypropylene fiber and the staining method, staining called supercritical (fluid), the supercritical carbon dioxide (scCO2) is used as a dyeing medium staining methods are known. For example, to Patent Document 1, using the scCO2, a polyester fiber material, such as polypropylene fiber material hydrophobic fibrous material, a variety of dyes staining is disclosed.
In addition, non-patent document 3, is 4, polypropylene fabric in scCO2 can be stained with a particular blue and yellow dyes are disclosed, these can be stained with a dye, stain staining with excellent fastness to be provided to the polypropylene fibers have been disclosed.
