Title DYED POLYPROPYLENE FIBER STRUCTURE AND GARMENT USING SAME
Abstract This dyed polypropylene fiber structure is characterized by being dyed with a red dye that is represented by general formula (1). (In the formula, each R1 independently represents a group selected from the group consisting of branched alkyl groups having 4-8 carbon atoms and aryl alkyl groups having 9-19 carbon atoms; and n represents a number of 1-3. The branched alkyl groups contain a quaternary carbon atom; and alkyl moieties of the aryl alkyl groups contain a quaternary carbon atom.)
Outline of related art and contending technology BACKGROUND ART
A polypropylene resin is an addition polymerization of propylene, a crystalline thermoplastic resin. The polypropylene resin for purification of petroleum as a raw material in the waste gas and propylene for inexpensive, low density enough to float on water (0.90-0.92g/cm3) and reduce the weight, 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, the polypropylene crystals in the relatively dense, very high hydrophobicity, the water swollen most not. For these reasons, conventional staining techniques and coloring of the polypropylene has been extremely difficult.
Currently on the market structure is the colored polypropylene fibers, polymer chip at the manufacturing stage of the color pigment was added to the stock solution (dyeing method) in the original thread is a method in most cases. In the manufacture of the textile dyeing method of the initial stage, that is, melt spinning of the color must be determined and the inconvenience, the color can be selected in a timely manner. In addition, the original thread is because the foreign matters such as pigment, colored yarn is not poor as compared with the regular thread, the single yarn fineness of the thin thread 1dtex cannot be stably produced. Further, in the case of changing the color of the thread produced, in the melt spinning apparatus of a next color in the color of the destination of the resin extruded resin must be substituted therefore, a large amount of time is required and a large amount of resin dropped. In consideration of profitability and the market price, the original thread 1 is one color must be produced a predetermined amount or more, naturally the number of colors will be limited.
Polypropylene as a synthetic resin include polyethylene, polyvinyl chloride, polystyrene and arranged as one of the four general-purpose synthetic resin and a large, inexpensive material cost and the superior characteristics in a very wide range of fields as the background (non-patent document 3) is used. In contrast, use of polypropylene as a synthetic fiber which is very limited (non-patent document 4). This is, not regular polypropylene yarn can be stained due to the small number of colors, then, only valid coloring method is the single yarn fineness of the original deposition method must be increased are mainly considered as the reason why not.
Polypropylene fibers freely to a method of coloring in the case where the practical use, there is no limitation on the number of colors, the single yarn fineness of the small (narrow) an inexpensive regular yarn can be colored. Therefore, a request for design is high, this has not been applied to the polypropylene fibers in the art, for example, the vehicle interior material in the art and in fields such as clothing, new applications utilizing the characteristics of the expected expansion.
1960 Generation of the dye by changing the molecular structure of the polypropylene fibers and aqueous staining is attempted, JP-1-5, non-patent document 5 to the dye for dyeing a layer of polypropylene with a few. Further, the non-patent document 6-11 according to the study of aqueous staining of polypropylene fibers, a very high hydrophobicity such as polypropylene for the dyes of the fiber, polyester fiber is commonly used for the dye having an extremely high hydrophobic than necessary. However, light resistance, washing, friction, various kinds of sublimation or the like all good fastness polypropylene fibers in an aqueous stain is stained with a dye which allows this result to the not yet been found.
To replace the aqueous staining of the staining as polypropylene fibers, referred to as supercritical (fluid) staining, supercritical carbon dioxide (scCO2) used as a staining medium staining methods are known. For example, to Patent Document 6, scCO2 is used, a polyester fiber material, such as polypropylene fiber material hydrophobic fibrous material, a variety of dyes staining is disclosed. Is the non-patent document 12-17, and currently on the market for the polyester or polypropylene fibers stained with a dye and super-critical has been described.
In addition, non-patent document 18, is 19, scCO2 polypropylene fabric can be stained in 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.
