Description
Technical Field
The invention relates to an artificial fiber material with health care and regulation effects on human skin and organs, in particular to functional artificial cotton containing a nano powder material.
Background
With the continuous development of scientific technology, from the viewpoint of ecology of textile consumer products, people are more concerned about the influence of textiles on the bodies of consumers, thereby initiating research on various functional artificial fiber materials. At present, functional rayon or its woven fabric developed mainly comprises viscose fiber containing industrial ceramic powder materials such as alumina, titanium dioxide, silica, zinc oxide, etc., such as functional woven fabric and its manufacturing method provided in chinese patent specification No. CN1030536C, medical nonwoven fabric containing inorganic oxide composite powder provided in chinese patent specification No. CN1049941C, etc. Such functional artificial viscose fibers generally have only an anti-ultraviolet function, an antibacterial deodorizing function and a far infrared ray radiating function, and lack a function of releasing negative ions. Their far infrared ray radiation performance is not high due to the limitation of the material property, and the normal emissivity is generally not more than 0.87, more under 0.85. Chinese patent application publication No. CN1227205A provides an inorganic oxide composite powder capable of inducing negative air ions and a fabric containing the same, but the inorganic oxide composite powder used in the fabric is a composite powder containing rare earth oxides, such as cerium oxide, thorium oxide, neodymium oxide, dysprosium oxide, lanthanum oxide, yttrium oxide, uranium oxide, and the like, and theserare earth oxides are expensive, and some of them are radioactive and may have adverse effects on human bodies. In addition, most of the inorganic oxide composite powders contained in the conventional functional fibers and woven fabrics thereof have relatively large particle sizes, generally about 500 nm, and some of them are even less than 50 μm, so that a large amount of fine powders are inevitably contained therein. The inorganic oxide composite powder of the functional fiber and the textile fabric thereof is contained in the artificial viscose fiber which is the main component, the diameter of the artificial viscose fiber is generally dozens of microns, and if the particle size of the added inorganic oxide composite powder is more than 500 nanometers, the strength of the fiber is greatly reduced. Meanwhile, the particle size of the inorganic oxide composite powder is too large, so that the specific surface area of the inorganic oxide composite powder is reduced, namely the area contacting with the outside is reduced, and the release function of negative ions is influenced.
Disclosure of Invention
The present invention has been made to overcome the above-mentioned disadvantages of the prior art, and an object of the present invention is to provide a functional artificial cotton containing a nano-powder material, which contains a plurality of nano-powders having permanent electrodes and no radioactive contamination, can greatly increase the amount of anions generated by ionizing moisture in the air, and has an excellent far infrared radiation function and an excellent ultraviolet radiation resistance function.
In order to achieve the purpose, the functional artificial cotton containing the nano powder material is the functional artificial viscose fiber which is formed by uniformly mixing the nano powder material with relevant functionality screened by repeated research and optimized combination in an artificial viscose solution carrier and carrying out spinning and other treatments and has the function of regulating the skin of a human body. The functional artificial cotton comprises the following components in parts by weight: 96-98% of pure artificial viscose fiber, 1.5-2.5% of natural tourmaline powder with the particle size of less than 100 nanometers and 0.5-1.5% of zinc oxide powder with the particle size of less than 100 nanometers.
Further, the preferred weight ratio of each component in the functional artificial cotton is as follows: 97-97.7% of pure artificial viscose fiber, 1.8-2.2% of natural tourmaline powder with the particle size of less than 100 nanometers and 0.5-0.8% of zinc oxide powder with the particle size of less than 100 nanometers.
The natural tourmaline powder is a functional powder prepared by processing natural tourmaline to nanometer particle size. The natural tourmaline is a silicate crystal of a trigonal system, and has a chemical general formula as follows:
NaR5Al6(Si6O18)(BO3)3(OH，F)4
wherein R represents a metal cation, which may be Mg2+、Fe2+、Fe3+、Li2+、Mn2+、Sr2+、Cr2+Etc. and Na+Can also be substituted by K+、Ca2+Plasma is substituted. Modern scientific research has proved that natural tourmaline has strong permanent electrode characteristic and can ionize air to generate a large amount of negative ions. Meanwhile, the natural tourmaline powder has an excellent function of radiating far infrared electromagnetic waves, and tests show that the normal emissivity of the natural tourmaline powder in the wavelength range of 4-15 microns is 0.88-0.90.
When the particle size of the zinc oxide powder is reduced to a nanometer size, the zinc oxide powder has a particularly strong shielding effect on ultraviolet rays, particularly ultraviolet rays with a wavelength of 350-400 nanometers (namely, a UV-A wave band). Meanwhile, the nano-zinc oxide powder can enhance the capability of photoproduction electron and hole, and when the nano-zinc oxide powder is irradiated by visible light or ultraviolet (Hv), the nano-zinc oxide powder can automatically decompose free moving electrons (e) in a system in which air and water exist-) While leaving positively charged holes (h)+) The stepwise reaction thereof is as follows:
the free moving electrons and positive holes generated in the zinc oxide powder can further improve the polarization degree of the natural tourmaline powder, and correspondingly greatly improve the capability of the natural tourmaline powder for ionizing water in the air to generate negative ions.
The invention has the advantages that: the developed functional artificial cotton utilizes the respective excellent physical characteristics of natural tourmaline ore and zinc oxide nano powder in artificial viscose fiber, and combines the natural tourmaline ore and the zinc oxide nano powder together for use, thereby generating good complementary action and obvious synergistic effect: firstly, the catalytic action of the permanent electric polarity of the natural tourmaline powder in the photoelectric decomposition of the zinc oxide powder is greatly enhanced, the specific surface area of thenatural tourmaline powder is greatly increased due to the particle size distribution below 100 nanometers, and the capability of automatically releasing negative ions is further enhanced, so that a large amount of negative ions can be generated by ionizing water in the air; secondly, the combination of natural tourmaline and zinc oxide powder keeps stronger and more stable far infrared electromagnetic wave emission characteristic than common ceramic powder materials, the normal emissivity of the far infrared ray is above 0.88, and simultaneously, the natural tourmaline and zinc oxide powder has good ultraviolet radiation shielding function; thirdly, the particle size of the selected natural tourmaline and zinc oxide powder is nano-scale, which is negligible compared with the diameter of the artificial viscose fiber carrier, thereby being beneficial to the uniform distribution of the natural tourmaline and the zinc oxide powder in the viscose fiber to play the inherent functions of the artificial viscose fiber and not influencing various strength and quality indexes of the viscose fiber; fourthly, the selected natural tourmaline and zinc oxide powder has no radioactive pollution, can exert the specific function of the natural tourmaline and zinc oxide powder for a long time without consuming energy, and is particularly suitable for preparing environment-friendly textiles with health care and regulation effects on human skins and organs.
Detailed Description
The functional artificial cotton containing nano-powder material according to the present invention will be further described in detail with reference to the following specific examples:
firstly, crushing, winnowing and crushing screened natural tourmaline ore into 200-325 meshes of powder, and processing zinc oxide into the same fineness. And secondly, mixing natural tourmaline powder particles and zinc oxide powder particles according to a set weight ratio, putting the mixture into a stirring ball mill, and processing the mixture into mixed powder with the particle size of less than 100 nanometers. Then adding the mixed powder into the artificial viscose solution with the set weight ratio, and fully and uniformly mixing. And spraying and solidifying the artificial viscose solution into viscose fiber filaments containing the nano powder material at a certain temperature and pressure. Finally, the functional artificial cotton can be prepared by post-treatment procedures such as stretching, refining, washing, oiling and the like. The above process is basically the same as the common viscose fiber manufacturing method, except for the difference in the weight ratio of the added components, and is not described herein again.
The experimental performance data of the rayon manufactured according to the above method in different weight ratios are listed below:
example 1: 97.6 percent of viscose fiber, 1.5 percent of tourmaline powder and 0.9 percent of zinc oxide powder; far infrared normal emissivity: 0.87, negative ion release amount: 1800 pieces/cm3。
Example 2: 97.4 percent of viscose fiber, 1.8 percent of tourmaline powder and 0.8 percent of zinc oxide powder; far infrared normal emissivity: 0.88, negative ion release amount: 3500 pieces/cm3。
Example 3: 97.3 percent of viscose fiber, 2.0 percent of tourmaline powder and 0.7 percent of zinc oxide powder; far infrared normal emissivity: 0.885, negative ion release amount: 3600 pieces/cm3。
Example 4: 97.2 percent of viscose fiber, 2.2 percent of tourmaline powder and 0.6 percent of zinc oxide powder; far infrared normal emissivity: 0.88, negative ion release amount: 3700 pieces/cm3。
Example 5: 97.0 percent of viscose fiber, 2.5 percent of tourmaline powder and 0.5 percent of zinc oxide powder; far infrared normal emissivity: 0.875, negative ion release amount: 2400/cm pieces/cm3。
The functional artificial cotton can be directly processed into functional non-woven fabrics, or can be blended with natural cotton according to a certain weight percentage to form functional blended cotton, and can be correspondingly woven into various functional fabrics.
The functional fabrics can emit far infrared electromagnetic waves with the wavelength of 4-15 microns required by a human body, and the normal emissivity of the functional fabrics is above 0.87. Under the radiation of far infrared rays in the wave band, the Chinese medicinal composition can expand blood vessels of human skin, increase body surface blood flow, improve tissue activity, obviously improve blood microcirculation, and has certain auxiliary treatment effect on cardiovascular diseases such as arteriosclerosis, hypertension and the like.
The huge number of weak electrodes contained in these functional fabrics can ionize the moisture in the air and generate a large amount of negative ions.
