Description

  The present invention relates to a dye composition for cellulose fibers and a method for producing a dyed product containing cellulose fibers.

  Reactive dyes are generally excellent in terms of light resistance and wet fastness, and are also used for dyeing natural or regenerated fibers such as cellulose fibers (for example, Patent Document 1).

  Conventional standard dyes are generally optimized for each type of fiber, and dedicated dyes are used depending on the type of fiber. For example, as a dye for cellulose fibers, C.I. I. Reactive Yellow 145, C.I. I. Reactive Yellow 176, C.I. I. Reactive Blue 2, C.I. I. Reactive Blue 144 and C.I. I. Reactive Blue 261 is known.

Japanese Patent No. 3754712

  However, according to the conventional dye for cellulose fibers, further improvement has been desired in terms of fastness to combined deterioration factors due to sweat and light, that is, fastness to sweat light resistance. In particular, in applications such as sportswear worn outdoors, for example, the lack of sweat light fastness of red dyes constituting the three primary colors has been regarded as a problem.

  Then, an object of this invention is to obtain the dyeing | staining containing a cellulose fiber which has sufficiently high sweat light fastness.

  As a result of intensive studies, the present inventor has sufficient light fastness to sweat by diverting a polyamide fiber dye originally developed mainly for dyeing polyamide fibers such as nylon fibers as a dye for cellulose fibers. The present inventors have found that a dyed product can be obtained and completed the present invention based on this finding.

  That is, this invention relates to the dye composition for cellulose fibers containing the reactive dye for polyamide fibers. Moreover, in another aspect, the present invention provides a dyed article containing cellulose fibers, comprising a step of dyeing the cellulose fibers of a base material containing cellulose fibers with a dye composition for cellulose fibers containing a reactive dye for polyamide fibers. It relates to a method of manufacturing.

  Cellulose fibers subjected to dyeing using the dye composition according to the present embodiment are, for example, cotton, hemp, rayon, cupra, tencel, or a blended fiber thereof. In particular, cotton is often used in applications requiring a high level of light fastness to sweat, and the technical significance of applying the dye composition of this embodiment is great.

  Next, a method for producing a dyed product will be described.

  The manufacturing method which concerns on this embodiment is equipped with the process of dye | staining this cellulose fiber of the base material containing a cellulose fiber with the dye composition which concerns on the above-mentioned embodiment.

  The base material used for dyeing contains at least cellulose fibers and may contain other natural and / or synthetic fibers blended with cellulose fibers. Cellulose fibers are selected from, for example, cotton, hemp, rayon, cupra, tencel, and combinations thereof.

  Examples of other natural fibers include silk, wool and cashmere. Examples of other synthetic fibers include polyethylene terephthalate (2GT), polypropylene terephthalate (3GT), polybutylene terephthalate (4GT), acetate, nylon, cationic diable polyester (CDP), polylactic acid, and vinylon fibers. The ratio of other natural and / or synthetic fibers in the substrate is not particularly limited, and can be appropriately determined by those skilled in the art.

  As used herein, the term “substrate” is intended to encompass any fiber product composed of fibers. The textile product as a base material includes the entire apparel product including filaments and yarns and a fabric formed therefrom. Examples of filaments and yarns include monofilaments, multifilaments, staple fibers, tows, high bulk staples, high bulk tows, spun yarns, blended yarns, processed yarns, false twisted yarns, irregular cross-section yarns, hollow yarns, conjugate yarns, partially oriented yarns (POY) ), Drawn yarn (DTY), POY-DTY, and sliver. Examples of fabrics include woven fabrics, knitted fabrics, non-woven fabrics, braids including strings and / or ropes, cottony high bulk fabrics, slivers, and porous sponges.

  The size, thickness, dimensions, etc. of the substrate are not particularly limited. The base material may be provided with or contain various additives generally used in the field according to the purpose. Additives include plasticizers, antioxidants, heat stabilizers, UV stabilizers, UV absorbers, light stabilizers, lubricants, fillers, anti-adhesive agents, antistatic agents, surface wetting improvers, incineration aids, Examples thereof include an anti-slip agent and a pigment.

  For dyeing the substrate with the dye composition, a dyeing technique usually used in this technical field can be employed. For example, methods usually used in the technical field such as dip dyeing (exhaust dyeing method), continuous dyeing (padding dyeing method), and printing method can be appropriately applied. Examples of the dip dyeing include a method using wine, jigger, or cheese dyeing. Examples of continuous dyeing include a cold pad batch method and a pad steam method. As the textile printing method, there are a screen printing method, a roller printing method, an ink jet method, and an electrophotographic method.

  The amount of the dye composition applied to the substrate is not necessarily limited. In the case of dip dyeing, the dye composition is preferably used at a ratio of 0.001% owf to 10% owf, more preferably 0.1% owf to 6% owf with respect to the substrate. In the case of continuous dyeing, a dye composition having a padding solution concentration of preferably 0.01 g / liter to 100 g / liter, more preferably 1 g / liter to 60 g / liter is used. In the case of printing, a dye composition having a printing paste concentration of preferably 0.01 g / kg to 100 g / kg, more preferably 1 g / kg to 60 g / kg is used.

  In dyeing, for example, mirabilite (sodium sulfate) and soda ash (sodium carbonate) are preferably added to the dye composition as dyeing aids. The concentration of sodium carbonate in the dye composition is preferably 5 g / liter to 100 g / liter, more preferably 10 g / liter to 80 g / liter. The concentration of sodium carbonate in the dye composition is preferably 1 g / liter to 30 g / liter, more preferably 5 g / liter to 25 g / liter.

  Although the dyeing | staining temperature is not specifically limited, It can set to temperature lower than the case of dyeing | staining of a normal polyamide fiber. The dyeing temperature (temperature of the dye composition) is preferably 40 to 90 ° C, more preferably 60 to 80 ° C. By dyeing the base material at a temperature lower than the temperature for dyeing the polyamide fiber, it is possible to avoid the cellulose fibers in the base material from being deteriorated at a high temperature.

  After dyeing the substrate, if necessary, the substrate can be subjected to treatments such as heat setting, washing, soaping and drying using means well known to those skilled in the art to obtain a dyed product.

  The dyed product obtained by the manufacturing method according to the present embodiment is rich in sharpness and fastness, and has excellent sweat light fastness. This dyed material is useful as a material for high-grade sport wear such as golf wear exposed to the outdoor environment.
