Description
The invention belongs to the field of textiles and materials, and particularly relates to a high-visibility nylon fiber textile and application thereof.
With the rapid development of road transportation industry and marine transportation industry, the occurrence frequency of accidents is increased. Related practitioners are in dangerous working environments, are highly concentrated in attention, often cannot find dangerous conditions in time, and actively and effectively avoid risks, so that the clothes with the high warning effect become necessary measures for solving the safety protection problems of the related practitioners. At present, warning clothes become professional clothes in various industries such as environmental sanitation, police, first aid, postal express delivery, buildings and the like, but warning effects of warning clothes worn by a plurality of workers are poor, safety of the workers is not guaranteed, and traffic smoothness is influenced greatly.
The high-visibility textile adopted by the warning clothes generally indicates the existence of operators by coating a reflective resin layer on the textile or dyeing the textile by adopting fluorescent dye, thereby playing a warning role. After the clothes are worn for a long time, the warning effect is reduced. This is because the personnel of dress mostly are in outdoor work, and the clothing receives sunshine for a long time and shines, leads to the resin layer to peel off or fluorescent dye takes place to decompose the sublimation, and surface color desalts, and optical properties reduces, and the safety protection effect reduces. If the garment is discarded and replaced in time, a large amount of waste of the garment can be caused, and the economic burden of the practitioner is increased.
And for high quality requirements for high visibility textiles, the new proposed ISO 20471: 2013 standard and JIS T8127: the 2015 standard is introduced in detail, the ISO standard mainly aims at the standardized quality requirements of European and American market high-visibility products, and the JIS standard mainly aims at the standardized quality requirements of Japanese market high-visibility products.
The ISO standard is different from the JIS standard mainly in that the ISO standard uses a xenon lamp light source for irradiation evaluation, and the JIS standard uses not only a xenon lamp light source but also high intensity irradiation of a carbon arc, and thus it is more difficult to satisfy the JIS standard. The technology solves the problem of light resistance of the ISO standard and solves the problem of carbon arc irradiation of the JIS standard.
Although there are many studies on high-visibility textiles, there are few high-visibility products meeting ISO standards and JIS standards, for example, patent document CN102926185A discloses a dyeing and finishing method of a polyester-cotton blended woven fluorescent fabric, which includes the steps of pretreatment, dyeing, post-treatment and post-finishing of the fabric, and the polyester-cotton fluorescent yellow fabric is mainly used for processing fire protection clothing. The protective clothing has a flame-retardant function, most of fire scenes are dense and dense, and effective connection in fire extinguishing of fire fighters on the scene is greatly influenced. After the fire fighter wears the firefighter uniform made of the polyester-cotton fluorescent yellow fabric, the reflection effect of the body of the firefighter is obviously improved, and the contact among the firefighters in the fire scene is effectively promoted, so that the fire extinguishing efficiency is improved, and the possibility of the firefighter being injured is reduced.
But because the crystallinity of nylon is higher, the color fastness after dyeing can have bad phenomenon, in addition, high visibility is used in the open air, the illumination is strong, and ordinary high-visibility nylon fabric can not have high visibility effect after long-term use, and can not meet the ISO standard.
Disclosure of Invention
The invention aims to provide a high-visibility yellow fluorescent nylon fiber textile with high productivity and extremely excellent light resistance, and warning clothing made of the high-visibility nylon fiber textile.
The technical solution of the invention is as follows:
the high-visibility nylon fiber textile is a fluorescent yellow woven or knitted fabric formed by 100% of nylon fibers, and the nylon fibers contain coumarin acid fluorescent yellow dye and rhodamine acid red dye; according to ISO 20471: 2013, irradiating the textile with a xenon lamp, or according to JIS T8127: 2015, when the textile is irradiated with carbon arc light or xenon lamp, the textile has CIE chromaticity coordinates (x, y) within the ranges of (0.387, 0.610), (0.356, 0.494), (0.398, 0.452) and (0.460, 0.540), and the minimum luminance value β is 0.70 or more.
In the invention, the nylon fiber textile processed by using the specific type of acid fluorescent yellow dye and the specific type of acid fluorescent red dye is different from the conventional products processed by coating and padding, and the light-resistant and color-changing performance is greatly improved even if 30g/m2The following light and thin products are also extremely excellent in visibility.
The high-visibility nylon fiber textile is a fluorescent yellow woven or knitted fabric formed by 100% of nylon fibers, and the nylon fibers contain coumarin acid fluorescent yellow dye and rhodamine acid fluorescent red dye.
The nylon fiber used in the present invention is preferably nylon 6 or nylon 66, but not limited thereto. The cross section shape can be round, and also can be a special shape such as triangle, quadrangle, etc.
The coumarin acidic fluorescent yellow dye used in the invention has a benzopyran structure, so that the fluorescent yellow dye has high fluorescence quantum yield, adjustable photochemistry and good fluorescent color development effect; in addition, the coumarin acidic fluorescent yellow dye also has a lactone structure, can inhibit the rotation of double bonds, greatly improves the light stability and has good color fastness.
The coumarin acid fluorescent yellow dye is a compound with a structure shown in the following formula 3 and a derivative thereof:
the acid fluorescent red dye used in the invention is rhodamine derivative dye. Compared with other azo and pyrrole derivatives and other fluorescent red dyes, the rhodamine acid fluorescent red dye has the advantages of higher light stability, wider wavelength range, higher fluorescence quantum yield, insensitivity to pH value and the like, and in addition, after the acid fluorescent red dye used by the invention and the coumarin acid fluorescent yellow dye are compounded and dyed, the CIE chromaticity coordinates (x, y) of the obtained textile tend to be more according to ISO 20471: 2013 standard or JIS T8127: the ranges ((0.387, 0.610), (0.356, 0.494), (0.398, 0.452) and (0.460, 0.540)) specified by the 2015 standard are central and, after irradiation by xenon or carbon arc lamps, the CIE chromaticity coordinates (x, y) of the textile do not exceed those according to ISO 20471: 2013 standard or JIS T8127: 2015 standard ((0.387, 0.610), (0.356, 0.494), (0.398, 0.452), and (0.460, 0.540)).
According to ISO 20471: 2013, irradiating the textile with a xenon lamp, or according to JIS T8127: 2015, when the textile is irradiated with carbon arc light or xenon lamp, the textile has CIE chromaticity coordinates (x, y) within the ranges of (0.387, 0.610), (0.356, 0.494), (0.398, 0.452) and (0.460, 0.540), and the minimum luminance value β is 0.70 or more. The rhodamine acid fluorescent red dye is a compound with a parent structure as shown in the following formula 4:
in the invention, 1-4 wt% of coumarin acidic fluorescent yellow dye is preferred. The preferable weight percentage of the rhodamine acid red dye is 0.005-0.02%. When the amount of the acid fluorescent yellow dye is less than 1% by weight, the color tends to be light and the high visibility effect tends to be poor, and there is a possibility that the CIE chromaticity coordinates (x, y) may not satisfy ISO 20471: 2013 standard or JIS T8127: the colorimetric requirements specified in the 2015 standard; when the amount of the acid fluorescent yellow dye is more than 4 wt%, the product may not meet the requirements of ISO 20471: 2013 standard or JIS T8127: the chromaticity requirements specified in 2015 standard, in addition, increase dyeing costs. If the amount of the acid fluorescent red dye is less than 0.005 wt%, the effect of adjusting the CIE chromaticity coordinate of the textile may not be achieved; when the amount of the composition exceeds 0.02 wt%, the CIE chromaticity coordinate of the textile exceeds ISO 20471: 2013 standard or JIS T8127: trend of chromaticity range specified in 2015 standard. According to ISO 20471: 2013 standard or JIS T8127: the initial CIE chromaticity coordinates (x, y) of the nylon textile of the present invention were measured in the range defined by (0.387, 0.610), (0.356, 0.494), (0.398, 0.452), and (0.460, 0.540) and the minimum luminance value β was 0.70 or more in the 2015 standard.
It is known that excessive exposure to ultraviolet rays may affect health, for example, sunburn, wrinkles, sunburn, etc., and generally requires clothes to have a function of absorbing or shielding ultraviolet rays, and inorganic ultraviolet absorbers such as titanium dioxide, etc., have a low affinity for fibers, and may have problems of poor fastness, poor ultraviolet durability, etc. Therefore, the present invention preferably further contains an organic ultraviolet absorber (organic UV absorber). The amount of the organic UV absorber can be adjusted as required, and is preferably 1-4 wt%. If the amount exceeds 4 wt%, the UV absorber absorbs a large amount of UV light, and the fluorescent dye may not obtain sufficient UV light to convert into fluorescence, so that the fluorescent color development effect of the dye is affected.

The organic ultraviolet absorber can absorb ultraviolet rays in a range of 300 to 400nm, and is advantageous for improving light resistance, and the non-reactive type UV absorber does not have a reactive matrix and is generally adsorbed on the surface of the fiber in a monomolecular state.
The high-visibility nylon fiber textile can meet the illumination requirements of ISO standard and JIS standard, and can also meet the fastness requirement of the standard. Washing fastness is changed to fade 4-5 grade, and pollution is 4 grade; the color fastness to light is more than 3-4 grade; the fastness to perspiration is more than grade 4; and the heat and pressure resistant fastness is more than 4-5 grade.

The resin component of the resin layer is not particularly limited, and an aqueous Polyurethane (PU) resin or a Polytetrafluoroethylene (PTFE) resin is preferable.
The high-visibility textile product of the present invention is obtainable by a method comprising the steps of:
putting 100% nylon fiber woven or knitted grey cloth into a dyeing machine, and uniformly mixing the grey cloth with processing liquid formed by coumarin fluorescent xanthic acid dye and rhodamine fluorescent red acid dye, wherein the bath ratio is 1: 5-50, and preserving the heat for 25-60 minutes at 80-110 ℃; and then fixing color, washing with water, drying and shaping by adopting a conventional condition method to obtain the product.
