Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application No. 62/784,937, filed on Dec. 26, 2018, the entirety of
which is incorporated by reference herein. The application is based
on, and claims priority from, Taiwan Application Serial Number
108120085, filed on Jun. 11, 2019, the disclosure of which is
hereby incorporated by reference herein in its entirety.
TECHNICAL FIELD
[0002] The technical field relates to a textile, and in particular
it relates to a fiber composition thereof.
BACKGROUND
[0003] It is well known that the specific range of the visible
light wavelength (400 nm to 780 nm) in sunlight is beneficial for
human skin, exhibiting such effects as anti-aging, whitening,
wrinkle reduction, collagen hyperplasia, and the like. For example,
the visible light wavelength of 480 nm to 530 nm may accelerate
blood circulation and activate cell, and the visible light
wavelength of 600 nm to 750 nm may stimulate cytochrome activation
of fibroblasts to help generate collagen. However, the other
wavelength range in sunlight such as 180 nm to 400 nm (i.e. UV),
which can be classified into UV-A (with wavelength of 320 nm to 400
nm), UV-B (with wavelength of 260 nm to 320 nm), and UV-C (with
wavelength of 180 nm to 290 nm). UV-A may penetrate the dermis to
age and relax the dermis, thereby forming wrinkles. UV-B results in
erythema in skin and severe edema, blisters, and peeling. UV-C has
shorter wavelength and potential carcinogenicity. Developing a
composite fiber to simultaneously block UV, shield near-IR, and
enhance the transmittance of visible light with a specific light
wavelength is the future direction of the textile industry.

polymer fiber; and a fluorescent dye combined with the polymer
fiber, wherein the light emission wavelength of the doped zinc
oxide particles and the light absorption wavelength of the
fluorescent dye overlap.
[0005] One embodiment of the disclosure provides a textile,

[0007] A detailed description is given in the following embodiments
with reference to the accompanying drawings.

DETAILED DESCRIPTION
[0018] In the following detailed description, for purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding of the disclosed embodiments. It
will be apparent, however, that one or more embodiments may be
practiced without these specific details. In other instances,
well-known structures and devices are schematically shown in order
to simplify the drawing.
[0019] Because humans wear clothing in most conditions, it is
beneficial to human health to wear clothing that may block harmful
light wavelength range and strengthen the wholesome light
wavelength range. One embodiment of the disclosure provides a
textile, in which the ratio of the visible light with specific
light wavelength range transmitting the textile is enhanced.
[0020] For example, one embodiment of the disclosure provides a
composite fiber including a polymer fiber, doped zinc oxide
particles, and fluorescent dye. The doped zinc oxide particles is
dispersed in the polymer fiber or combined with the polymer fiber.
For example, the doped zinc oxide particles can be dispersed in the
polymer, and then melt spun and false twisted to form a yarn. The
yarn is then woven to form a textile such as cloth. As such, the
doped zinc oxide particles are dispersed in the polymer fiber. The
polymer fiber with the doped zinc oxide particles dispersed therein
can be spun to form a yarn, and the yarn can be woven to form a
textile. Then, the yarn or the textile can be soaked in an aqueous
solution of the fluorescent dye, such that the fluorescent dye is
combined with the polymer fiber. On the other hand, the fluorescent
dye and the doped zinc oxide particles are dispersed in a solution,
and the yarn or the textile (spun or woven from a polymer fiber)
are soaked in the dispersion, such that the doped zinc oxide
particles and the fluorescent dye are combined with the polymer
fiber. No matter what the method is selected to form the composite
fiber, the light emission wavelength of the doped zinc oxide
particles and the light absorption wavelength of the fluorescent
dye overlap. For example, the light emission wavelength of the
doped zinc oxide particles and the light absorption wavelength of
the fluorescent dye are partially overlapped. For example, the
doped zinc oxide particles have a light emission wavelength of 400
nm to 780 nm, and the fluorescent dye has a light absorption
wavelength of 180 nm to 600 nm. If the light emission wavelength of
the doped zinc oxide particles and the light absorption wavelength
of the fluorescent dye do not overlap, the emission light intensity
of a combination of the fluorescent dye and the doped zinc oxide
particles will be similar to the emission light intensity of the
fluorescent dye alone. The doped zinc oxide may block most of UV
and IR and emit light of specific wavelength. The fluorescent dye
may absorb the light emitted by the doped zinc oxide particles, and
then enhance the emission of visible light of a specific
wavelength.
[0021] In one embodiment, the polymer fiber includes polyester
fiber, polyacrylonitrile fiber, polyacrylate fiber, cellulose
fiber, polyethylene fiber, polypropylene fiber, polyamide fiber,
polyurethane fiber, cellulose acetate fiber, animal fiber, or a
combination thereof. The composite fiber formed from the polymer
fiber can be spun to a yarn with other polymer fiber (without the
doped zinc oxide particles and the fluorescent dye), and the yarn
is woven to form a textile such as cloth.
[0022] In one embodiment, the doped zinc oxide particles can be
doped aluminum, gallium, tin, or a combination thereof, and (a)
weight of aluminum, gallium, tin, or a combination thereof and (b)
total weight of zinc and aluminum, gallium, tin, or a combination
thereof have a ratio of 0.1:100 to 20:100. If (a) weight of
aluminum, gallium, tin, or a combination thereof has an overly high
or overly low ratio, the appearance of the composite fiber, the
yarn containing the composite fiber, and the textile containing the
composite fiber has an overly high haze degree due to overly low
transmittance. The doped zinc oxide particles can be prepared by
the following steps. The nitrate or sulfate of zinc and chloride or
sulfate of doping element (containing aluminum, gallium, or tin)
are formulated to a mixture solution with a concentration of 0.5
mL/L to 5.0 mL/L. The weight of the doping element and the total
weight of zinc and the doping element may have a ratio of 0.1% to
20%, such as 0.1% to 10%. The mixture solution and the ammonium
bicarbonate are dropwise added into water to obtain evenly doped
and white alkaline zinc carbonate precipitation. During the
dropwise addition, the temperature is kept at 40.degree. C., the pH
value is controlled at 7.0 to 7.5, and the solution is vigorously
stirred. The precipitation is washed, separated, and baking dried
to obtain powders. The powders are sintered under a mixture gas of
hydrogen and argon at a temperature of 400.degree. C. to
700.degree. C. for a period of 30 minutes to 60 minutes to obtain
doped zinc oxide particles that are doped with aluminum, gallium,
tin, or a combination thereof. The doped zinc oxide particles may
have a diameter of 50 nm to 1000 nm, which can be tuned by the
sintering temperature and sintering period. Overly large doped zinc
oxide particles are difficult to spin to form the polymer fiber
with the doped zinc oxide particles dispersed therein. On the other
hand, the overly large zinc oxide particles may negatively
influence the transmittance of the composite fiber and even the
breathability of the textile. Overly small doped zinc oxide are
easily aggregated, which are difficult to be evenly dispersed in
the polymer fiber or evenly combined with the polymer fiber.
[0023] In one embodiment, the doped zinc oxide particles and the
composite fiber have a weight ratio of 0.1:99.9 to 20:80.
Alternatively, the composite fiber further includes a plurality of
titanium oxide particles dispersed in the polymer fiber or combined
with the polymer fiber, and the total weight of the titanium oxide
particles and the doped zinc oxide particles and the weight of the
composite fiber have a weight ratio of 0.1:99.9 to 20:80. The
amount of the doped zinc oxide (or the doped zinc oxide particles
and the titanium oxide particles) that is too low cannot
efficiently prevent UV and IR from transmitting through the
textile. The amount of the doped zinc oxide ratio (or the doped
zinc oxide particles and the titanium oxide particles) that is too
high may increase the textile weight and reduce the breathability
of the textile.
[0024] In general, the fluorescent dye has a light absorption
wavelength of 180 nm to 600 nm and a light emission wavelength of
400 nm to 780 nm. For example, the fluorescent dye can be
1,8-naphthalimide (for cotton fiber, cellulose fiber, or wool
fiber), coumarin (for polyester fiber), or hemicyanine (for
polyacrylonitrile fiber, silk, wool, or nylon fiber). As described
above, the light emission wavelength can be controlled by
fluorescent dye to achieve the effects on human skin, such as
anti-aging, whitening, wrinkle reduction, collagen hyperplasia, and
the like. In one embodiment, the fluorescent dye and the composite
fiber have a weight ratio of 0.01:100 to 20:100. The amount of the
fluorescent dye that is too low cannot efficiently enhance the
emission intensity of the specific visible light. The amount of the
fluorescent dye that is too high cannot further increase the
emission intensity of the specific visible light but increase the
cost.
[0025] The composite fiber can be used to form a textile. For
example, the composite fiber can be used to fabricate a yarn, and
the yarn is then woven to form a textile such as cloth. In one
embodiment, the composite fiber can be used to fabricate a yarn
with other polymer fiber (without the doped zinc oxide particles
and/or the fluorescent dye), and the yarn is then woven to form a
textile such as cloth. On the other hand, the other polymer fiber
can be directly used to prepare the other yarn at first, and then
the yarn (containing the composite fiber) and the other yarn are
woven to form a textile such as cloth. The composition of the other
polymer fiber can be similar to or different from the composition
of the polymer fiber of the composite fiber. For example, the melt
liquid of polyester and the doped zinc oxide can be extruded from
spinning nozzle to form a yarn. The yarn is then stretched and
cooled, and wound as caked to fabricate synthetic fiber. On the
other hand, several pieces of processing equipment or nozzle
devices can be utilized to develop texture yarn such as wool-like,
silk-like, cotton-like, flax-like, slub-like, variegated wool-like,
cloud yarn-like, thick and thin yarn-like, or the like.
[0026] In one embodiment, the polymer fiber with the doped zinc
oxide particles dispersed therein can be dyed to form a composite
fiber. The composite fiber can be used to form a yarn, and the yarn
is woven to form a textile such as cloth. Alternatively, the
polymer fiber with the doped zinc oxide particles dispersed therein
can be used to form a yarn. The yarn is dyed and then woven to form
a textile such as cloth. Alternatively, the polymer fiber with the
doped zinc oxide particles dispersed therein can be used to form a
yarn, and the yarn is woven to form a textile such as cloth. The
textile is then dyed. The above mentioned fiber, yarn, or textile
can be dyed by sublimation method, water bath method, or coating
method. For example, the sublimation method may include put the
fluorescent dye in a crucible, put the fiber, the yarn, or the
textile above the crucible, and heat the crucible to sublimate the
fluorescent dye, such that the fluorescent dye vapor is combined
with the polymer fiber to form the composite fiber. For example,
the water bath method may include dissolve the fluorescent dye in
water, and soaking the fiber, the yarn, or the textile into the
aqueous solution, such that the fluorescent dye is combined with
the polymer fiber to form the composite fiber. Alternatively, the
fluorescent dye is dissolved in a solution, and the solution is
coated to the fiber, the yarn, or the textile, such that the
fluorescent dye is combined with the polymer fiber to form the
composite fiber. In one embodiment, the doped zinc oxide particles
and the fluorescent dye can be directly dispersed in a solution,
and the dispersion is coated to the polymer fiber (free of the
doped zinc oxide particles and the fluorescent dye before coating),
the yarn containing the polymer fiber, or the textile containing
the polymer fiber, such that the doped zinc oxide particles and the
fluorescent dye are combined with the polymer fiber. No matter what
method is selected for dyeing, the fluorescent dye can be combined
with the polymer fiber, and the doped zinc oxide particles can be
dispersed in the polymer fiber or combined with the polymer fiber.
The light emission wavelength of the doped zinc oxide particles in
the composite fiber, the yarn, and the textile and the light
absorption wavelength of the fluorescent dye overlap to further
enhance the emission intensity of the specific visible light
wavelength.
[0027] In one embodiment, the doped zinc oxide particles can be
dispersed in the first polymer fiber or combined with the first
polymer fiber. On the other hand, the fluorescent dye can be
combined with the second polymer fiber. The first polymer fiber
(containing the doped zinc oxide particles) and the second polymer
fiber (containing the fluorescent dye) can be spun together to form
the same yarn, or respectively spun to form the different yarns.
The yarns can be further woven to form a textile such as cloth. In
one embodiment, each of the first polymer fiber and the second
polymer fiber is independently polyester fiber, polyacrylonitrile
fiber, polyacrylate fiber, cellulose fiber, polyethylene fiber,
polypropylene fiber, polyamide fiber, polyurethane fiber, cellulose
acetate fiber, animal fiber, or a combination thereof. The first
polymer fiber can be similar to or different from the second
polymer fiber. Whatever, the light emission wavelength of the doped
zinc oxide particles and the light absorption wavelength of the
fluorescent dye overlap to further enhance the emission intensity
of specific visible light wavelength.
[0028] Below, exemplary embodiments will be described in detail
with reference to accompanying drawings so as to be easily realized
by a person having ordinary knowledge in the art. The inventive
concept may be embodied in various forms without being limited to
the exemplary embodiments set forth herein. Descriptions of
well-known parts are omitted for clarity, and like reference
numerals refer to like elements throughout.

Preparation Example 1
Preparation of Aluminum Doped Zinc Oxide Particles
[0029] Zinc nitrate and aluminum chloride were formulated to form a
mixture solution with a concentration of 1 mL/L, wherein the
addition weight of aluminum and the total weight of zinc and
aluminum have a ratio of 1:100. Both the mixture solution and
ammonium bicarbonate were dropwise added into water to obtain
evenly doped and white alkaline zinc carbonate precipitation.
During the dropwise addition, the temperature was kept at
40.degree. C., the pH value was controlled at 7.0 to 7.5, and the
solution was vigorously stirred. The precipitation was washed,
separated, and baking dried to obtain powders. The powders were
sintered under a mixture gas of hydrogen and argon at a temperature
of 400.degree. C. to 700.degree. C. for a period of 30 minutes to
60 minutes to obtain aluminum doped zinc oxide particles. The
aluminum doped zinc oxide particles had a diameter of 50 nm to 100
nm, which could be tuned by modifying the sintering temperature and
period. For example, the particles with a diameter of 50 nm to 150
nm could be obtained by sintering at a temperature of 400.degree.
C. for a period of 60 minutes. The particles with a diameter of
larger than 500 nm could be obtained by sintering at a temperature
of 700.degree. C. for a period of 30 minutes.

chloride being replaced with gallium chloride.
Example 1
[0031] 1 part by weight of gallium doped zinc oxide particles (with
a diameter of 50 nm to 150 nm) were dispersed in 99 parts by weight
of polyethylene terephthalate (PET). Polyester particles of the
above composition were melt spun and false twisted to form a yarn
with the standard T75/72DTY. The yarn was further woven to form a
textile.
[0032] 0.7 parts by weight of yellow fluorescent coumarin dye

aqueous solution of the fluorescent dye at room temperature. The
aqueous solution of the fluorescent dye was then heated to
130.degree. C. by a heating rate of 2.degree. C./min, and kept at
130.degree. C. for 40 minutes. The dyed textile was then cooled,
washed with water, washed with soap, and baking dried to obtain a
yellow textile. The yellow textile had a UV proof of 50+, which was
measured by the standard FTTS-FA-008. The yellow textile was
irradiated by an excitation light source (325 nm) to measure its
fluorescent spectroscopic spectrum, as shown in FIG. 1. The yellow
textile was irradiated by UV-VIS light (380 nm-780 nm) to measure
its transmittance spectrum, as shown in FIG. 2.

diameter of 50 nm to 150 nm) were dispersed in 97.6 parts by weight
of PET. Polyester particles of the above composition were melt spun
and false twisted to form a yarn with the standard T75/72DTY. The
yarn was further woven to form a textile. 0.7 parts by weight of
yellow fluorescent coumarin dye (10GN, commercially available from
Gemmy Dye and Chemical, Co., Ltd, based on 100 parts by weight of
the textile) was dissolved in 2000 parts by weight of water. The
textile was soaked in the aqueous solution of the fluorescent dye
at room temperature. The aqueous solution of the fluorescent dye
was then heated to 130.degree. C. by a heating rate of 2.degree.
C./min, and kept at 130.degree. C. for 40 minutes. The dyed textile
was then cooled, washed with water, washed with soap, and baking
dried to obtain a yellow textile. The yellow textile had a UV proof
of 50+, which was measured by the standard FTTS-FA-008. The yellow
textile was irradiated by an excitation light source (325 nm) to
measure its fluorescent spectroscopic spectrum, as shown in FIG. 1.
Compared to Comparative Example 1, the yellow textile in Example 1
had higher emission intensity, and its light emission wavelength
was red-shift, as shown in FIG. 1. Furthermore, the yellow textile
was irradiated by UV-VIS light (380 nm-780 nm) to measure its
transmittance spectrum, as shown in FIG. 2. Compared to Comparative
Example 1, the yellow textile in Example 1 has a higher
transmittance for visible light with specific wavelength, and the
transmitting visible light wavelength was red-shift, as shown in
FIG. 2.

dispersed in 98.7 parts by weight of PET. Polyester particles of
the above composition were melt spun and false twisted to form a
yarn with the standard T75/72DTY. The yarn was further woven to
form a textile.
[0035] 0.7 parts by weight of yellow fluorescent coumarin dye

Ltd, based on 100 parts by weight of the textile) was dissolved in
2000 parts by weight of water. The textile was soaked in the
aqueous solution of the fluorescent dye at room temperature. The
aqueous solution of the fluorescent dye was then heated to
130.degree. C. by a heating rate of 2.degree. C./min, and kept at

spectrum, as shown in FIG. 8. The non-dyed textile did not have the
emission for specific visible light wavelength. The dyed composite
fiber with the doped zinc oxide particles had stronger emission
intensity for specific visible light wavelength than the dyed PET
fiber.
Example 22
[0079] 0.48 parts by weight of aluminum doped zinc oxide particles
(with a diameter of 50 nm to 150 nm) were dispersed in 99.52 parts
by weight of PET. Polyester particles of the above composition were
melt spun and false twisted to form a yarn with the standard
T75/72DTY. The yarn was further woven to form a textile.
[0080] 0.34 parts by weight of yellow fluorescent coumarin dye
(10GN, commercially available from Gemmy Dye and Chemical, Co.,
Ltd, based on 100 parts by weight of the textile) was dissolved in
2000 parts by weight of water. The textile was soaked in the
aqueous solution of the fluorescent dye at room temperature. The
aqueous solution of the fluorescent dye was then heated to
130.degree. C. by a heating rate of 2.degree. C./min, and kept at
130.degree. C. for 40 minutes. The dyed textile was then cooled,
washed with water, washed with soap, and baking dried to obtain a
yellow textile. The yellow textile was irradiated by an excitation
light source (325 nm) to measure its fluorescent spectroscopic
spectrum, as shown in FIG. 9. Afterward, the yellow textile was
washed with water 20 times, and then irradiated by an excitation
light source (325 nm) to measure its fluorescent spectroscopic
spectrum, as shown in FIG. 9. Because the yellow textile after
being washed with water 20 times still had a certain degree of the
fluorescent emission, the dye and the textile had excellent
adhesion, as shown in FIG. 9.
