Description

Composite fiber and fabric

This disclosure is about fabrics, and more specifically about its fiber composition.

It is currently known that specific wavelengths in the range of visible light wavelengths (400nm to 780nm) in sunlight have beneficial effects on human skin such as anti-aging, whitening, texture improvement, and collagen proliferation. For example, 480nm to 530nm can speed up blood circulation and activate cells. 600nm to 750nm can stimulate the cytochrome activation of fibroblasts to facilitate the production of collagen. However, other wavelength ranges in sunlight, such as 180nm to 400nm, are ultraviolet light, which can be classified as UV-A (light wave wavelength is 320~400nm), which can penetrate into the dermis of the skin, causing it to age and relax, and wrinkles appear. UV-B (light wave) The wavelength is 260~320nm), which can cause erythema on the skin. In severe cases, it may also be accompanied by edema, blisters, peeling, and UV-C (wavelength of light wave is 180~290nm). The wavelength is shorter and may cause cancer. The development of composite fibers that can simultaneously isolate ultraviolet light, shield near-infrared rays, and enhance the penetration of visible light of the aforementioned specific wavelengths is the future development direction of the textile industry technology.

The composite fiber provided by an embodiment of the present disclosure includes: a polymer fiber; doped zinc oxide particles dispersed in the polymer fiber or bonded to the polymer fiber; and fluorescent dye bonded to the polymer fiber, in which the oxide is doped The light emission wavelength of the zinc particles overlaps with the light absorption wavelength of the fluorescent dye.

The fabric provided by an embodiment of the present disclosure includes: composite fibers, including: first polymer fibers; doped with zinc oxide particles, dispersed in the first polymer fibers or bonded to the first polymer fibers; and fluorescent dyes, combined To the first polymer fiber, the light emission wavelength of the doped zinc oxide particles overlaps the light absorption wavelength of the fluorescent dye.

The fabric provided by an embodiment of the present disclosure includes: a first polymer fiber and a second polymer fiber; doped with zinc oxide particles, dispersed in the first polymer fiber or bonded to the first polymer fiber; and fluorescent dye, Bonded to the second polymer fiber, in which the light emission wavelength of the doped zinc oxide particles overlaps with the light absorption wavelength of the fluorescent dye.

Since the human body wears clothes most of the time, if the clothes can block the light in the wavelength range harmful to the human body and enhance the light in the wavelength range beneficial to the human body, it is beneficial to the health of the human body wearing the clothes. In order to achieve the above goals, the fabric provided by the embodiments of the present disclosure can increase the proportion of visible light penetrating the fabric in a specific wavelength range.

For example, the composite fiber provided by an embodiment of the present disclosure includes polymer fibers, doped zinc oxide particles, and fluorescent dyes. The above-mentioned doped zinc oxide particles are dispersed in the polymer fiber or bonded to the polymer fiber. For example, the doped zinc oxide particles can be dispersed in the polymer, and then melt-spinned and false-twisted into yarns and woven into fabrics. In this way, the doped zinc oxide particles are dispersed in the polymer fiber. Then, the yarn or fabric spun from the polymer fiber with doped zinc oxide particles dispersed therein can be immersed in an aqueous solution of fluorescent dye to bind the fluorescent dye to the polymer fiber. On the other hand, the fluorescent dye can be dispersed in the solution together with the doped zinc oxide particles, and the yarn or fabric spun from the fiber can be immersed in the dispersion liquid to combine the doped zinc oxide particles and the fluorescent dye into the yarn. The polymer fiber of thread or fabric. Regardless of the method used, the light emission wavelength of the doped zinc oxide particles overlaps with the light absorption wavelength of the fluorescent dye. For example, the light emission wavelength of the doped zinc oxide particles partially overlaps the light absorption wavelength of the fluorescent dye. For example, the wavelength of light emitted by the doped zinc oxide particles is between 400 nm and 780 nm, and the light absorption wavelength of the fluorescent dye is between 180 nm and 600 nm. If the light emission wavelength of the doped zinc oxide particles does not overlap with the light absorption wavelength of the fluorescent dye, the emission intensity of the fluorescent dye doped with zinc oxide particles will be similar to that of the fluorescent dye alone. Doped zinc oxide particles can block most of the ultraviolet and infrared rays, and emit light of specific wavelengths. After the fluorescent dye absorbs the light emitted by the doped zinc oxide particles, it will intensify the emission of visible light of a specific wavelength.

In an 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 of the above. The composite fibers formed by the above polymer fibers can be spun with other polymer fibers that do not contain doped zinc oxide particles or fluorescent dyes into yarns, and then the yarns are woven into fabrics such as cloth.

In one embodiment, the doped zinc oxide particles may be doped with aluminum, gallium, tin, or a combination of the foregoing, and the weight of (a) aluminum, gallium, tin, or a combination of the foregoing is the same as (b) zinc and aluminum, gallium The ratio between the total weight of, tin, or a combination of the above is between 0.1:100 and 20:100. If (a) the ratio of aluminum, gallium, tin, or the above combination is too low or too high, the light transmittance of the composite fiber, the yarn containing the composite fiber, and the fabric containing the composite fiber will be too low, causing the appearance of fog Too high. The method for forming the above-mentioned doped zinc oxide particles can be: preparing a mixed solution of zinc nitrate or sulfate and the chloride or sulfate of doping elements (including gallium, aluminum, and tin) (with a concentration of 0.5 ml/L) ~5.0ml/L), the addition amount of doping elements can be 0.1%-20% of the total weight of zinc and doping elements, such as 0.1%-10%. The above mixed solution and the ammonium bicarbonate solution are added dropwise to the water, and the pH value is controlled at 7.0-7.5 while maintaining at about 40° C., while vigorously stirring to obtain a uniformly doped white basic zinc carbonate precipitate. The above-mentioned precipitate is washed and separated and dried, and the obtained powder is sintered under a mixture of hydrogen and argon at a sintering temperature of 400° C. to 700° C., and a time of 30 minutes to 60 minutes. After sintering, zinc oxide particles doped with aluminum, gallium, tin, or a combination of the above are obtained. The particle size of the doped zinc oxide particles can be adjusted by the sintering temperature and the sintering time to form particles with a particle size between 50 nm and 1000 nm. If the zinc oxide doped particles are too large, it may be difficult to spin to form a polymer fiber with the zinc oxide doped particles dispersed therein. On the other hand, too large particles doped with zinc oxide may affect the light transmittance of the composite fiber and even reduce the air permeability of the fabric. If the particles doped with zinc oxide are too small, agglomeration problems are likely to occur, and on the contrary, it is difficult to be uniformly dispersed in the polymer fiber or uniformly bonded to the polymer fiber.

In an embodiment, the weight ratio of the doped zinc oxide particles to the composite fiber is between 0.1:99.9 and 20:80. In another embodiment, the composite fiber further includes a plurality of titanium dioxide particles dispersed in the polymer fiber or bonded to the polymer fiber, and the ratio between the total weight of the titanium dioxide particles and the doped zinc oxide particles and the weight of the composite fiber Between 0.1:99.9 and 20:80. If the ratio of doped zinc oxide particles (or doped zinc oxide particles and titanium dioxide particles) is too low, it will not be able to effectively block ultraviolet and infrared rays from penetrating the fabric. If the ratio of doped zinc oxide particles (or doped zinc oxide particles to titanium dioxide particles) is too high, it may increase the weight of the fabric and reduce the air permeability of the fabric.

Generally speaking, the light absorption wavelength of the fluorescent dye can be between 180 nm and 600 nm, and the light emission wavelength can be between 400 nm and 780 nm. For example, the fluorescent dyes can be 1,8-naphthalimides (suitable for cotton, cellulose, or wool fibers), coumarins (suitable for polyester fibers), or hemicyanines (Suitable for polyacrylonitrile fiber, silk, wool, or nylon fiber). As mentioned above, the wavelength range of the emitted light is controlled by fluorescent dyes, so that it has anti-aging, whitening, texture improvement and collagen enhancement effects on human skin. In one embodiment, the weight ratio of the fluorescent dye to the composite fiber is between 0.01:100 and 20:100. If the ratio of the fluorescent dye is too low, the radiation intensity of specific visible light cannot be effectively increased. If the proportion of the fluorescent dye is too high, the radiation intensity of the specific visible light cannot be further increased and the cost will increase.

The aforementioned composite fibers can be used to form fabrics. For example, the above-mentioned composite fibers can be made into yarns, and the yarns can be woven into fabrics such as cloth. In one embodiment, the composite fiber can be combined with other polymer fibers (without doped zinc oxide particles and/or fluorescent dyes) to form a yarn, and then the yarn is woven into a fabric such as cloth. On the other hand, other polymer fibers can be directly made into other yarns and then woven with yarns containing composite fibers to form fabrics such as cloth. The composition of other polymer fibers may be the same as or different from the composition of the polymer fibers in the composite fiber. For example, the melt of polyester and doped zinc oxide particles can be extruded and spun into a spinning nozzle, and then stretched and cooled, and then the silk cake is wound to make synthetic fibers. Various processing equipment or nozzle devices can also be used to develop various processed yarns such as wool-like, silk-like, cotton-like, hemp-like, slub-like, wool-like variegated, cloud-like yarn, or fat-thin yarn.

In one embodiment, the polymer fibers with doped zinc oxide particles dispersed therein can be dyed to form composite fibers and then made into yarns, which are then woven into fabrics such as cloth. In another embodiment, the polymer fibers with doped zinc oxide particles dispersed therein can be made into yarns and then dyed, and then woven into fabrics such as cloth. In other embodiments, polymer fibers with doped zinc oxide particles dispersed therein can be made into yarns, which are then woven into fabrics such as cloth and then dyed. The dyeing method of the above-mentioned fiber, yarn, or fabric may be a sublimation method, a water bath method, or a coating method. For example, the sublimation method can place fluorescent dyes in a crucible and place fibers, yarns, or fabrics on the crucible; then heat the crucible to sublime the fluorescent dyes so that the vapors of the fluorescent dyes are bound to the polymerization Fabric fibers to form composite fibers. For example, the water bath method can dissolve fluorescent dyes in water, and immerse fibers, yarns, or fabrics in an aqueous solution to bind the fluorescent dyes to polymer fibers to form composite fibers. On the other hand, the fluorescent dye can be dissolved in a solution, and the solution can be applied to the fiber, yarn, or fabric to bind the fluorescent dye to the polymer fiber to form a composite fiber. In one embodiment, the doped zinc oxide particles and fluorescent dye can also be directly dispersed in the solution, and the dispersion liquid can be applied to the polymer fiber (without doped zinc oxide particles and fluorescent dye), containing the above The yarn of the polymer fiber, or the fabric containing the above-mentioned polymer fiber, binds the doped zinc oxide particles and the fluorescent dye to the polymer fiber. No matter what method is used for dyeing, fluorescent dyes can be bound to polymer fibers, and doped zinc oxide particles can be dispersed in or bound to polymer fibers. The light emission wavelength of the doped zinc oxide particles in the composite fiber, yarn, and fabric overlaps with the light absorption wavelength of the fluorescent dye to further increase the emission intensity of a specific visible light wavelength.

In an embodiment, the doped zinc oxide particles may be dispersed in the first polymer fiber or bonded to the first polymer fiber. On the other hand, fluorescent dyes can be bound to the second polymer fiber. The first polymer fiber (containing doped zinc oxide particles) and the second polymer fiber (containing fluorescent dye) can be spun into the same yarn, or each spun into different threads, and then the yarn is woven into a fabric such as Cloth. In an embodiment, the first polymer fiber and the second polymer fiber are each polyester fiber, polyacrylonitrile fiber, polyacrylate fiber, cellulose fiber, polyethylene fiber, polypropylene fiber, polyamide fiber , Polyurethane fiber, cellulose acetate fiber, animal fiber, or a combination of the above. The first polymer fiber and the second polymer fiber may be the same or different. In any case, the light emission wavelength of the doped zinc oxide particles in the fabric overlaps with the light absorption wavelength of the fluorescent dye to further increase the emission intensity of the specific visible light wavelength.
