Colored fiber fabric and method for producing colored fiber fabric
The present invention provides a colored fiber fabric and the like that can be colored in various colors including bright colors and have excellent color fastness to light. The colored fiber fabric includes: a fiber fabric; a white pigment adhering to at least one surface of the fiber fabric via a binder resin; and a resin layer that contains a color pigment and is provided on the white pigment.
1. A colored fiber fabric comprising:
a fiber fabric;
a white pigment adhering to at least one surface of the fiber fabric via a binder resin, the white pigment and the binder resin forming a white resin layer on the at least one surface of the fiber fabric; and
a resin layer that contains a color pigment, the resin layer being provided above the white resin layer such that the white resin layer is an undercoating layer,
wherein the color pigment contains a fluorescent pigment,
wherein the resin layer that contains the color pigment has a thickness greater than a thickness of the white resin layer,
wherein the colored fiber fabric has a light fastness rating of Grade 4 or higher and/or satisfies requirements specified in 5.2 Colour after Xenon Test according to ISO 20471: 2013, the light fastness rating being measured by exposure method 3 specified in Test methods for colour fastness to enclosed carbon arc lamp light (JIS L0842: 2004 7.2 c), and wherein the colored fiber fabric is colored in colors that satisfy the luminance factors and the range of the color chromaticity coordinates of fluorescent yellow, fluorescent orange red, and fluorescent red specified in 5.1 Colour Performance Requirements of New Material according to ISO 20471: 2013.
2. The colored fiber fabric according to claim 1 ,
wherein the white pigment contains at least one selected from zinc oxide, titanium oxide, zinc sulfide, barium sulfate, barium carbonate, calcium carbonate, calcium sulfate, white lead, basic lead sulfate, lead sulfate, asbetine, clay, silica, white carbon, diatomaceous earth, talc, magnesium carbonate, alumina white, gloss white, satin white, and antimony oxide.
3. The colored fiber fabric according to claim 1 ,
wherein the fiber fabric contains an aromatic polyamide fiber.
4. Clothing comprising, at least in part, the colored fiber fabric according to claim 1 .
5. The colored fiber fabric according to claim 1 , wherein the white resin layer is porous.
6. The colored fiber fabric according to claim 1 , wherein the white resin layer has a thickness of 50 μm or less.
7. The colored fiber fabric according to claim 1 , wherein a total amount of the white pigment and the binder resin adhering to the fiber fabric ranges from 1 g/m 2 to 100 g/m 2 , inclusive.
8. The colored fiber fabric according to claim 1 , wherein the resin layer that contains the color pigment contains a color pigment that exhibits fluorescence and a color pigment that does not exhibit fluorescence.
9. The colored fiber fabric according to claim 1 , wherein the resin layer that contains the color pigment contains a white fluorescent pigment.
10. The colored fiber fabric according to claim 1 , wherein the resin layer that contains the color pigment contains an ultraviolet absorbing agent.
11. The colored fiber fabric according to claim 1 , wherein the resin layer that contains the color pigment has a thickness ranging from 0.1 μm to 50 μm, inclusive.
12. The colored fiber fabric according to claim 1 , wherein a total amount of a resin adhering to the fiber fabric ranges from 1 g/m 2 to 100 g/m 2 , inclusive, the resin being included in the resin layer that contains the color pigment.
13. The colored fiber fabric according to claim 10 , wherein the ultraviolet absorbing agent is a benzotriazole-based compound.
14. The colored fiber fabric according to claim 10 , wherein the ultraviolet absorbing agent contains a benzotriazole-based copolymer.
