Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to sportswear fabric dyed in different colors, more specifically, it relates to sportswear fabrics dyed in different colors, more specifically,
The present invention relates to a sportswear fabric containing elastic yarn and having elasticity.

(Prior Art) Conventionally, interlaced knitted fabrics of polyurethane elastic yarns and polyamide fiber yarns have been mainly used as stretchable fabrics for swimwear due to their color development and fit properties.

(Problems to be Solved by the Invention) However, such knitted fabrics are difficult to dye in different colors, and have the disadvantage of poor design. Although there have been attempts to dye different colors using , it is difficult to obtain a clear different color effect even though the difference in shading can be achieved. Furthermore, polyamide fibers also have the disadvantage that dyed products tend to fade or lose strength when exposed to disinfectant chlorine.

An object of the present invention is to provide a sportswear fabric dyed in a bright different color by piece dyeing.

′! ! Another object of the present invention is to provide a sportswear fabric dyed in different colors that has excellent elasticity and fit and is free from the disadvantages of lowering the elongation recovery properties and strength of elastic yarns due to piece dyeing.

A further object is to provide fabrics in which the wetness, lightfastness and chlorine resistance of dyeings are of the highest order.

(Means for solving all the problems) The present invention consists of an elastic yarn (A), a polyester fiber dyeable with atmospheric cation dye (a3), a polyamide fiber (0 and optionally a polyester fiber other than component (3)), A characteristic feature is that the polyester fiber (CB) dyeable with normal pressure cation dye is dyed with a cation dye, and the polyamide fiber (C) is dyed with an acid dye in a different color.

Examples of the elastic threads used in the present invention include polyester elastomer elastic threads, polyamide elastomer elastic threads, polyurethane elastomer elastic threads, fluorine-containing diystomer elastic threads, polycarbonate elastomer elastic threads, etc. In particular, polyurethane elastomer elastic threads Yarn, polyester elastomer elastic yarn is preferred. Examples of polyurethane elastomers include polyurethane distoners obtained by reacting polymer diols such as polyester diols, polyether diols, and polycaponate diols with polyisocyanates, low molecular chain extenders, and optionally terminal cappers. In particular, an n7'5 elastic yarn formed from a polyether type polyurethane elastomer is preferred because it quickly improves f'L7''c stability.The appropriate denier of the elastic yarn is usually 20 to 100 deniers, and it is preferred. is 30 to 70 deniers.Also, either coverlink yarn or bare yarn may be used.

′! Next, the polyester fiber dyeable with normal pressure cation dye used in the present invention is formed from alkylene polyester. Preferably, the total acid component contains 1 to 6 mol of the anti-reanionic group-containing ester-forming component, and the total of this component and the acid component other than component (A) and/or the glycol component. Alkylene 1" containing 3 to 20 mol % of phthalate-based copolymerized polyester with a small bottom shape m and a.

The anionic group-containing ester-forming component (4) is as follows:
5-sodium sulfoisophthalic acid, sulfosuccinic acid,
4-sulfonaphthalene-2,7-dicarboxylic acid, 5(4
In addition to -sulfophenoxyfisophthalic acid, sulfonic acid group-containing glycols may be mentioned, and 5-sodium sulfoisophthalic acid is particularly preferred.

Further, additional copolymerizable components Q3) other than component (2) include acid components such as isophthalic acid, adipic acid, sebacic acid, and glutaric acid, diethylene glycol, diethylene glycol, neopentyl glycol, and
Glycol components such as 0 or less polyether glycols may be mentioned, but polyether glycols are preferred, and polyether glycols represented by the general formula CI] are especially preferred.

15.12. j is an integer from 2 to 4. ) In addition, as specific examples of R in the above formula (1), for example, linear aliphatic hydrocarbon groups such as ecH, +-, side groups such as -CH, -C-CH, Fatty products with seven chains.

Examples include raw hydrocarbon groups, hydrogen groups on all aliphatic rings such as -■-, and the like.

The additional copolymer component (the odor may be one produced by the condensation of alkylene glycol in the polymerization of polyester).

In order to obtain low-temperature setting properties, vivid dyeability, atmospheric dyeability, and improved color fastness, it is necessary not only to make the product cationic dyeable, but also to fully copolymerize the additional copolymer components. be. When used for ropes, the fibers have excellent hydrolysis resistance, alkali hydrolysis resistance, low temperature setting properties,
The disadvantage is that color fastness and the like are reduced, and on the other hand, when only a large amount of the additional copolymerization component is used, not only the physical properties of the fiber are poor, but also the low temperature setting property and dimensional stability are insufficient.

The polyester fiber dyeable with normal pressure cation dyes may be filament, spun, or a composite thereof, but filament is particularly preferred.

The cross-sectional shape of the fibers may be circular, triangular, octagonal, uneven, or even, and may be either dull or prite, but 0-filament yarn is particularly preferable for irregular cross-sections and bright yarns due to sharpness, texture, etc. The denier does not need to be specially considered, but it is usually 20 to 100 denier, preferably 30 to 70 denier, and the single fiber denier is usually 0.5 to 5 denier, preferably 1 to 3 denier. . The fiber dyeable with atmospheric cation dyes may be used alone or, if desired, in combination with other fibers within the scope of the invention. The polyamide fibers used in the present invention include nylon 6, nylon 6.6, nylon 6,9, and nylon 6. 10. Examples include fibers such as nylon 6.12, and the denier, form, etc. of these fibers are selected from those similar to those of polyester fibers dyeable with atmospheric pressure cation dyes. I prefer the single fiber denier to be somewhat larger.
2 to 5 denier is good.

In the present invention, it is further possible to leave a white color after dyeing by using C in combination with polyester fibers other than normal pressure cation dyeable polyester fibers, thereby providing fabrics rich in design. In the present invention, fibers other than those mentioned above may be mixed as appropriate without departing from the gist of the present invention.

In the present invention, the above-mentioned elastic yarn (A), a yarn consisting entirely of atmospheric pressure cation dye dyeable fiber a3), polyamide fiber (
C) A yarn mainly composed of ' and optionally a component (B
) Polyester fibers other than ■) Using threads that are entirely based 5! , knitted fabrics are manufactured by a certain company, but interlaced knitting is particularly preferred in consideration of stretchability and fit.

The knitted fabric may be either a horizontal knitted fabric or a warp knitted fabric, but a warp i' knitted fabric is preferred from the viewpoint of functionality for sportswear. (Ls t') It may be knitted using a Kosto knitting machine or a Raschel knitting machine. However, it is necessary to knit three or more knitted sheets with different elongation of the fibers.

The thus obtained 'rL fabric is usually scoured, relaxed and dried, then heat set at a temperature of 150 to 190°C, preferably 180°C to 160°C, and dyed in different colors using cationic dyes and acid dyes. The cationic dye used is preferably a dispersion type, and the dyeing conditions are immersion dyeing at 90-110°C for 20-120 minutes, preferably 40-60 minutes, or steaming after applying the dye solution. Dye solid phase. Different color dyeing may be applied to the print,
Also, a combination of dyeing and printing may be used.The fixation after printing is carried out by superheated steam treatment at 120°C or lower, preferably 110°C or lower, and 1 liter of pressurized steam at 130-170°C for 3-30 minutes. 0 In particular, fixation by atmospheric dyeing or atmospheric steaming is preferred. 0 The acidic dye used is acidic dye,
These include acidic metal-containing dyes and sulfonic acid group-containing fluorescent dyes.

In this way, it is possible to obtain f'Lfc sportswear fabric that is vividly dyed in a different color without impairing the elongation recovery properties and physical properties of the postal yarn. However, if desired, at any stage, mold-proofing, antibacterial, antistatic, stain-proofing, water-repellent, oil-repellent, breathable and waterproof, polyurethane elastomer,
Thermoforming processing etc. can be performed. In particular, organopolysiloxane and /''! friend can be improved in elasticity and texture by treatment with an antifouling agent having a polyoxyalkylene chain.As the organopolysiloxane, polyether-modified organopolysiloxane is particularly preferred. shi'／
'O'! 7t, as a post-treatment agent, a cationic group-containing compound is excellent for the atmospheric pressure cation dyeable polyester fiber, and an anionic group-containing compound is excellent for polyamide fiber from the viewpoint of durability.
