Description
CROSS-REFERENCE TO RELATED PATENT APPLICATION
[0001] This application claims the benefit of priority to Taiwan
Patent Application No. 107147004, filed on Dec. 25, 2018. The
entire content of the above identified application is incorporated
herein by reference.
[0002] Some references, which may include patents, patent
applications and various publications, may be cited and discussed
in the description of this disclosure. The citation and/or
discussion of such references is provided merely to clarify the
description of the present disclosure and is not an admission that
any such reference is "prior art" to the disclosure described
herein. All references cited and discussed in this specification
are incorporated herein by reference in their entireties and to the
same extent as if each reference was individually incorporated by
reference.
FIELD OF THE DISCLOSURE
[0003] The present disclosure relates to a textile and a textile
fiber, and in particular, to a heat-insulating dark cool-feeling
textile and a dark cool-feeling fiber thereof.
BACKGROUND OF THE DISCLOSURE
[0004] The cool-feeling effect of a conventional textile fiber and
textile is produced by adding mineral powders or jade powders with
low specific heat or by silking in a profiled section to increase
the heat conduction performance thereof. For example, cool-feeling
textile fiber Acotex Gpowertech Co., Ltd. emphasizes that when a
person wearing clothes with the cool-feeling textile fiber
technology ACOTEX.RTM. enters an air-conditioned room from the
outside, the clothes made of material with low specific heat can
achieve an instant cool feeling effect. However, when being outside
in the sun, the person wearing the clothes with the cool-feeling
textile fiber technology ACOTEX.RTM. would feel hotter due to the
low specific heat of the material of the clothes.
[0005] In addition, some conventional fibers use textile materials
with good water absorption such as cotton, viscose rayon,
cuprammonium rayon, or hydrophilized synthetic fibers to obtain an
instant cool feeling. In such a case, no heating effect is caused
even under high temperature environments. However, the disadvantage
of such conventional fibers is that after a large amount of water
is absorbed, such fibers do not dry easily due to the excellent
moisturizing effect thereof. If a person wearing such clothes
enters an air-conditioned room after exercise, since the clothes
have absorbed a large amount of sweat, the wet clothes can
instantly become cold and cause the person to catch a cold.
SUMMARY OF THE DISCLOSURE
[0006] To solve the foregoing problems of the prior art, the main
objective of the present disclosure is to provide a heat-insulating
dark cool-feeling textile and a dark cool-feeling fiber thereof,
which allow the fiber to have good near-infrared light reflectivity
and heat-insulating effect in a dark state, achieve low costs, and
be easily manufactured.
[0007] To achieve the foregoing objective, one of the main
objectives of the present disclosure is to provide a dark
cool-feeling fiber, wherein the textile fiber includes one or more
of artificial fibers and synthetic fibers. In addition, 0.05-5 wt %
(weight percentage) of nano microparticles is added based on the
total weight of the textile fiber to improve the near-infrared
light reflectivity and dark color effect of the textile fiber. The
nano microparticles are a mixture of any two or more selected from
iron (Fe), copper (Cu), nickel (Ni), cobalt (Co), and chromium (Cr)
with the particle size of 300-1,800 nm. Preferably, 0.1-3 wt % of
nano microparticles with the particle size of 500-1,500 nm is added
based on the total weight of the textile fiber. More preferably,
0.3-1.5 wt % of nano microparticles with the particle size of
700-1,300 nm is added based on the total weight of the textile
fiber. Specific examples of the nano microparticles include at
least one of the following combinations: [0008] 1) 5-300 parts by
weight of Fe and 5-200 parts by weight of Cr; [0009] 2) 5-300 parts
by weight of Fe and 5-200 parts by weight of Ni; [0010] 3) 5-300
parts by weight of Cu and 5-300 parts by weight of Ni; [0011] 4)
10-150 parts by weight of Fe and 10-100 parts by weight of Cr;
[0012] 5) 10-150 parts by weight of Fe and 10-100 parts by weight
of Ni; or [0013] 6) 10-150 parts by weight of Cu and 10-150 parts
by weight of Ni.
[0014] Another objective of the present disclosure is to provide a
heat-insulating dark cool-feeling textile, obtained by knitting or
weaving the dark cool-feeling fiber of the present invention. The
heat-insulating dark cool-feeling textile has a heat-insulating
effect of about 12.degree. C. and the near-infrared light
reflectivity of 50%-80% compared with a generic black fabric.
[0015] The beneficial effects of the dark cool-feeling fiber and
the textile prepared therefrom of the present invention include: a
certain ratio of nano microparticles with the particle size of
500-1,500 nm is added to the textile fiber, so that compared with a
textile of the same gram weight, color and weaving method, the dark
cool-feeling fiber of the present disclosure has greatly improved
near-infrared light reflectivity and heat insulation property of
the textile. In particular, compared with the existing dark
heat-insulating fibers, the present disclosure is low in
manufacturing cost, simple in manufacturing process, and easy to
industrialize.
[0016] For a further understanding of the features and the
technical content of the present disclosure, reference is made to
the detailed description and accompanying drawings of the present
disclosure. However, the accompanying drawings are merely provided
for reference and description, and are not intended to limit the
present disclosure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] The dark cool-feeling fiber of the present disclosure is a
textile fiber having both heat insulation and cool feeling
functions. 0.05-5 wt % of nano microparticles is added in the
textile fiber based on the total weight of the textile fiber, and
the nano microparticles are a mixture of any two or more selected
from Fe, Cu, Ni, Co, and Cr with the particle size of 300-1,800 nm.
Preferably, 0.1-3 wt % of nano microparticles with the particle
size of 700-1,300 nm is added, to improve the near-infrared light
reflectivity and dark color effect of the textile fiber.
[0021] The textile fiber includes one or more of artificial fibers
and synthetic fibers.
[0022] In the dark cool-feeling fiber of the present disclosure,
the nano microparticles may be added by using a conventional melt
spinning technique. A preparation method of the dark cool-feeling
fiber of the present disclosure includes the following steps.
[0023] A. A predetermined ratio of the nano microparticles is
prepared into a heat-insulating cool-feeling master batch with a
natural polymer material or a synthetic polymer material. For
example, Fe and Cr having a weight ratio of 24:1 are prepared into
a heat-insulating cool-feeling master batch with the natural
polymer material or the synthetic polymer material.
[0024] B. The prepared heat-insulating cool-feeling master batch is
uniformly mixed with another polymer material master batch or
synthetic polymer material master batch.
[0025] C. The mixture is subjected to screw mixing and then
extruded through a spinning mechanism, to obtain a dark
cool-feeling fiber.
[0026] Hereinafter, the dark cool-feeling fiber of the present
disclosure is processed into a fiber-fabric product and a fabric as
an illustrative example, and the heat insulation property is
evaluated according to the following method.
[0027] 1. Lamp Box Test (Heat-Insulating Effect Test):
[0028] Referring to FIG. 1, according to the nano-label TN-037
specification, one of two fabric samples is a standard sample, and
the other is a test sample, where the temperature of the standard
sample is controlled at 46.degree. C..+-.2.degree. C. The standard
sample and the test sample are respectively placed on a left
semicircular tube and a right semicircular tube in the lamp box,
and are simultaneously irradiated with a 175 W infrared lamp for 10
min to observe the temperature difference.
[0029] Required level: the temperature difference is +2.degree. C.
or more, which indicates that there is a heat-insulating
effect.
[0030] 2. Color Test:
[0031] The color of the fabric is tested with a spectrophotometer
(model: X-rite Color-Eye 70000A).
[0032] 3. Near-Infrared Light Reflectivity Detection:
[0033] The near-infrared light reflectivity of the fiber products
and fabrics is tested with a UV/Vis/NIR spectrometer (model: Lambda
750 manufactured by Perkin Elmer). The fabric sample is folded into
16 layers for testing, in order to avoid the influence of fiber
density of the products and fabrics on the accuracy of
near-infrared light reflectivity measurement.
[0034] Experimental method: the fabric sample is folded into a
16-layer structure, and the reflectivity of the sample in the
wavelength range of 200 nm to 2,500 nm is measured by a UV-Vis
spectrometer to observe the reflecting capacity of the fabric
sample in near-infrared light (780-2,500 nm).
EXAMPLE 1
[0035] In the dark cool-feeling fiber prepared in this example, 0.3
wt % of nano microparticles is added to the textile fiber based on
the total weight of the textile fiber by using a melt spinning
technique, and the nano microparticles have the particle size of
about 700 nm and include 32 parts by weight of Fe and 32 parts by
weight of Cr, as well as other trace elements that need to be
added.
[0036] Control samples of this example:
[0037] 1. Sample A: a generic black yarn prepared by adding 4.5 wt
% of a black master batch is used as a control sample, where the
black master batch is prepared by adding 30 wt % of carbon black to
a PET resin.
[0038] 2. Sample B: a generic black yarn prepared by adding 7.0 wt
% of a black master batch is used as a control sample, where the
black master batch is prepared by adding 30 wt % of carbon black to
a PET resin.
[0039] The heat-insulating effect and color of the obtained fiber
and the control samples are tested, and the results are shown in
Tables 1 and 2. The results of near-infrared light reflectivity
detection are shown in FIG. 2.

[0040] It can be observed from the test results of Table 1 that
under the same gram weight, color and weaving method, compared with
the generic black fabric, the heat insulation property of the
textile prepared in this example can isolate a heat source and
reduce the temperature of the fabric by about 12.degree. C.
[0041] According to the test results of Table 2, the textile
prepared in this example has only a small difference in the L*, a*,
and b* values from the generic black fabric, and the color display
under the naked eye is substantially black.
[0042] According to the near-infrared light reflectivity detection
of FIG. 2, the near-infrared light (780-1,300 nm) reflectivity and
heat-insulating capability of the textile prepared in this example
are about 50-85%, and the near-infrared light (780-1,300nm)
reflectivity and heat-insulating capability of samples A and B of
the generic black fabric are only about 4-6%. Apparently, the fiber
textile prepared by the present disclosure has higher near-infrared
light reflectivity than the generic black fabric.
EXAMPLE 2
[0043] The dark cool-feeling fiber is prepared in the same method
as Example 1, but the nano microparticles with the particle size of
about 1,300 nm are used in the textile fiber and include 32 parts
by weight of Fe and 32 parts by weight of Cr, as well as other
trace elements that need to be added.
[0044] Similarly, samples A and B of Example 1 are used as control
samples of this example. The heat-insulating effect and color of
the prepared fiber and control samples are tested, and the results
are shown in Tables 3 and 4. The results of near-infrared light
reflectivity detection are shown in FIG. 3.

[0045] It can be seen from the test results of Table 3 that under
the same gram weight, color and weaving method, compared with the
generic black fabric, the heat insulation property of the textile
prepared by the textile fibers of the present disclosure can
isolate a heat source and reduce the temperature of the fabric by
about 12.degree. C.
[0046] According to the test results of Table 4, the textile
prepared by the fiber of the present disclosure has only a small
difference in the L*, a*, and b* values from the generic black
fabric, and the color display under the naked eye is substantially
black.
[0047] According to the near-infrared light reflectivity detection
of FIG. 3, the near-infrared light (780-1,600 nm) reflectivity and
heat-insulating capability of the textile prepared in this example
are about 55-85%, and the near-infrared light (780-1,600nm)
reflectivity and heat-insulating capability of samples A and B of
the generic black fabric are only about 4-6%. Apparently, the fiber
textile prepared by the present disclosure has higher near-infrared
light reflectivity than the generic black fabric.
EXAMPLE 3
[0048] The dark cool-feeling fiber is prepared in the same method
as Example 1, but the nano microparticles used in the textile fiber
include 32 parts by weight of Fe and 32 parts by weight of Ni, as
well as other trace elements that need to be added.
[0049] Similarly, samples A and B of Example 1 are control samples
of this example. Compared with the generic black fabric, the
heat-insulating effect is still about 12.degree. C., and the
near-infrared light reflectivity is 50-80%.
[0050] The contents above are only preferred feasible embodiments
of the present disclosure, and are not intended to limit the
protection scope of the claims of the present disclosure.
Therefore, any equivalent technical changes made according to the
description and the accompanying drawings of the present disclosure
fall within the protection scope of the claims of the present
disclosure.
