Technical Field

The invention relates to a nano-pretreatment long-acting functional composite material and a fabric thereof, in particular to a composite material which is prepared by uniformly mixing a metal functional material and a plastic material according to a preset weight percentage, can be applied to a spinning process, is spun into a plurality of textile fiber materials through the spinning process, and is formed into the fabric after processing procedures (such as weaving processing, needle rolling machinery, carding mechanical processing and other … processing procedures) are carried out on the textile fiber materials.

Background

In recent years, with the progress of materials and techniques of the manufacturing machines, the precision degree and the weaving capability of the textile machinery are increasingly exquisite, which not only improves the yield and quality of the finished products of the fabrics (including woven fabrics made by the weaving machinery or non-woven fabrics made by the needle rolling machinery or carding machinery, also called non-woven fabrics), but also breaks through the limitation and restriction of the fabric design, so that the fabric structure is not only easy to perfect, and through the design of various fabric structures, the finished products of the fabrics with various characteristics can be produced, so that the finished products of the fabrics are not limited to be used in the purposes of clothes or decoration, and the application range of the finished products of the fabrics can be expanded to other various fields, such as packaging fabrics, general industrial fabrics, fabrics for building construction, or even shells of automobiles and steamships, even to be expanded to the special fields of medicine and the like, therefore, the fabric is not only an article which is visible everywhere in daily life, but also plays an important role in other occasions, and the brand-open corner becomes an indispensable key technology in various special fields.

For general people, the general purpose of the fabric is mostly used for clothes, and as the living standard is improved, the requirements of people for clothes are becoming stricter and more, and are not limited to the basic cold shielding body, therefore, in order to obtain the favor of consumers, various functional clothes (or functional clothes) are developed by many manufacturers, such as: waterproof, perspire, antibiotic, deodorization, fire-retardant, heat accumulation heat preservation (far infrared ray), ultraviolet resistance, anti-electromagnetic wave … etc. can be expected to establish market advantage through creating the high added value and wearing article. At present, the production mode of functional clothes generally adopts post-treatment processing technology, namely, manufacturers can utilize soaking, coating … and other treatments to attach different functional agents to fiber materials (such as cotton fabrics); then, through the procedures of low-temperature plasma irradiation, drying heat treatment …, etc., the functional agents are firmly immersed into the fiber material or adhered to the surface of the fiber material, so that the product made of the fiber material can exert the expected effect.

For example, some manufacturers immerse clean fibers in a silver nanoparticle suspension (i.e., a functional agent), pressurize the silver nanoparticle suspension to be uniformly absorbed into the fibers, remove excessive liquid, and finally perform a drying process to fix the silver nanoparticles onto the fibers, so as to manufacture antibacterial products (such as underwear, medical bedsheets and covers, hemostatic gauze, etc.); or, some manufacturers will mix the far infrared particles into the adhesive (such as modified acrylic white emulsion), grind into the coating with fineness (fineness) less than 0.5 micron (mum), print and apply it on the fabric, and process at high temperature, can form the product with far infrared function; or, some manufacturers mix Xylitol (Xylitol) in the adhesive, and then the mixture is dipped, pressed and baked in sequence to be attached to the fabric, so that the Xylitol absorbs water and then generates an endothermic reaction to form a product with a cooling cool feeling; or, some manufacturers will first prepare coffee polyol to synthesize polyurethane dispersion, and then coat the polyurethane dispersion on the surface of the fabric, and then after drying, the product with waterproof and breathable effects can be formed; alternatively, the manufacturer would grind zeolite (zeolite) into nanoparticles (200nm) and then coat the nanoparticles on the surface of cotton cloth and polyester cloth to scatter the uv light into the space through the porous structure of zeolite to form a product capable of blocking uv light; alternatively, the industry mixes zinc oxide (ZnO) particles of 20nm to 100nm with Polystyrene (Polystyrene) to form an emulsion, and then fixes the zinc oxide particles on cotton fabric by an impregnation coating method to form a product with high sun protection factor (UPF).

However, the inventor found that the functional agents of the aforementioned products are additionally processed on the fiber material, so that after washing and rubbing, the functional agents are easily and gradually separated from the surface of the fiber material, and the products lose the functions required by manufacturers (such as far infrared ray, waterproof and breathable properties, ultraviolet ray blocking …, etc.), which not only results in the problem of poor durability of the functional clothing effect, but also makes consumers feel poor experience of using the functional clothing, and therefore, how to effectively solve the aforementioned problems to provide a fabric product with more stable and durable functionality becomes an important subject of the present invention.

Disclosure of Invention

Generally speaking, the effect of the fabric is mainly from the characteristics of the textile fiber material, but the fabric made by the aforementioned conventional post-treatment processing technology is very likely to cause the problem of unstable and non-durable functionality, therefore, the inventor has made long-term research and experiments to develop and design the long-lasting composite material of nano pre-treatment and the fabric thereof of the present invention, and it is expected that the disclosure of the present invention can form a composite material by pre-treatment of the metal functional material containing noble metal particles and the plastic material, and then make the required functional textile fiber material, so as to provide a textile product with more stable and durable functionality for users, thereby effectively solving the conventional problems.

Another object of the present invention is to provide a long-lasting functional fabric with nanometer pretreatment, which is prepared from a textile fiber material through a processing procedure, wherein the textile fiber material is prepared from a composite material through a spinning procedure, wherein the composite material is prepared from at least a metal functional material and a plastic material, the metal functional material accounts for 18 to 22 weight percent of the composite material, the plastic material accounts for 78 to 82 weight percent of the composite material, and the metal functional material at least comprises nano platinum particles, nano silver particles, nano zinc oxide particles and far infrared particles, so that the fabric is prepared from the composite material through the spinning procedure without adding a functional agent, and the metal functional material contained in the fabric cannot be easily separated after long-term use, it is ensured that the fabric always has the predetermined function imparted by the metallic functional material.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.

The invention relates to a nanometer pretreatment long-acting functional composite material and a fabric thereof. In addition, in the spinning process, if the proportion of the metal functional material is too much, the spinning mouth is easy to be blocked, so after a lot of repeated experiments, the weight percentage of the metal functional material in the composite material is 18-22%, and the weight percentage of the plastic material in the composite material is 78-82%.

In this embodiment, the metal functional material at least comprises far infrared particles, nano platinum particles, nano silver particles and nano zinc oxide particles, and the efficacy and weight percentage of each component are described, first, the far infrared particles are substances having far infrared radiation characteristics, and account for 18 to 22 weight percentage of the metal functional material, and have a size of 0.1 to 1 micron (in this embodiment, the average particle size of the far infrared particles is 0.16 micron), and further, the far infrared has a very strong permeability, and can penetrate into subcutaneous tissues to cause the vibration of water molecules in blood, so as to further refine inert water (i.e. four hydrogen molecules and one oxygen molecule are combined, and cannot pass through cell membranes) into independent water molecules (i.e. two hydrogen molecules and one oxygen molecule are combined), so as to improve the oxygen content of the body, revitalizes cells, enables people to be more spiritual, improves the disease resistance and delays aging.

In conclusion, the far infrared particles can be classified into oxides (e.g., aluminum oxide (Al) according to their chemical structures₂O₃) Zirconium oxide (ZrO)₂) Magnesium oxide (MgO), titanium oxide (TiO)₂) Silicon oxide (SiO)₂) …, etc.), carbides (e.g.: zirconium carbide (ZrC), silicon carbide (SiC), boron carbide (B)₄C) Tantalum carbide (TaC) …, etc.), borides (e.g.: titanium boride (TiB)₂) Zirconium boride (ZrB)₂) Chromium boride (CrB)₂) …, etc.), silicide (e.g.: titanium silicide (TiSi)₂) Molybdenum silicide (MoSi)₂) Tungsten silicide (WSi)₂) …, etc.) and nitrides (e.g.: silicon nitride (Si)₃N₄) Titanium nitride (TiN) …, etc.), therefore, the far infrared ray particles mentioned in the following description of the present invention generally refer to any one of the particles of the far infrared radiation substances mentioned above, or a mixture of the particles of the plurality of far infrared radiation substances mentioned above, and it is well known in advance.

The nano platinum particles account for 30ppm to 120ppm by weight of the metal functional material, and have a size of 10 nm to 50 nm (in this embodiment, the average particle size of the nano platinum particles is 23.8 nm), wherein platinum (Pt) is a chemically very stable inert noble metal, which is silver in normal state, but if it is made into nano-scale particles, the color will be changed from silver to black, so it is also called platinum black, at this time, due to the size effect and large proportion of surface area effect, the platinum metal will be changed from inert substance to catalyst with excellent activity, which can generate atomic-like characteristic, and has electric potential, and can reach the antioxidation effect by transmitting the electric potential to active oxygen. In addition, since the reflectivity of the nano platinum particles to light energy and heat energy is very low, usually less than 1%, that is, the nano platinum particles with a diameter of about several micrometers can completely extinguish the light energy and heat energy, and thus the nano platinum particles can be attached to the far infrared particles, so that the far infrared particles can utilize the nano platinum particles as a high-efficiency energy conversion material to absorb the surrounding light energy and heat energy and convert the same into far infrared rays. Thus, when the fabric is attached to the surface of a human body or is very close to the human body, far infrared rays can be fed back into the human body, and the function and the effect of promoting blood circulation and metabolism are achieved.

Furthermore, the nano silver (Ag) particles account for 1 to 3 wt% of the metal functional material, and have a size of 5 to 20nm (in this embodiment, the average particle size of the nano silver particles is 6.8 nm), wherein the nano silver particles have a fine particle size, so that the overall surface area is greatly increased, the activity is increased, and active silver ions are easily released to attract and rapidly combine with sulfhydryl groups on enzyme proteins in the bacteria, so that the sulfhydryl group-containing enzymes are inactivated, and the bacteria die, and the positively charged silver ions are adsorbed to each other after contacting with negatively charged microbial cells, and penetrate the outer cell walls of the microorganisms to denature the inside of the microorganisms, reduce the growth capacity, and prevent the cells from metabolizing and propagating until the cells die, and in addition, when the bacteria are killed by the silver ions, the silver ions are released from the dead bacteria, the repeated action is continuously carried out on other live bacteria until all the bacteria are killed, so that the silver nanoparticles have excellent antibacterial and sterilizing effects without illumination activation, can inhibit the growth of mould and effectively achieve the function of corrosion prevention.

The zinc oxide nanoparticles (ZnO) account for the rest of the metal functional material and have a size of 5 nm to 20nm (in this embodiment, the ZnO nanoparticles have an average particle size of 5.3 nm), and when other kinds of ZnO particles are added to the metal functional material, the ZnO particles can be reduced in weight percentage, wherein the ZnO decomposes free-moving negatively-charged electrons (e-) under sunlight, particularly ultraviolet irradiation, while leaving positively-charged holes (H +), which are associated with water and water molecules (H) in the air₂O) when meeting, the nanometer zinc oxide particle can be used as a strong oxidant to degrade organic matters such as mould, bacteria, virus and the like so as to kill the mould, bacteria and virus; in addition, the nano zinc oxide particles also have the effects of no toxicity, no odor, no irritation to skin, no deterioration, good thermal stability, static resistance, infrared absorption and the like.

Based on the characteristics of the nano metal particles (especially, noble metal) and the far infrared particles, in this embodiment, referring to fig. 1, a worker can add the ground far infrared particles and a dispersant (e.g., water-soluble acryl powder) into a stirring tank to form a uniform slurry, wherein the slurry has a solid content of 30% to 35%, and then sequentially add an alkaline reducing agent (e.g., potassium hydroxide (KOH), sodium hydroxide (NaOH) …, etc.) and a zinc chloride dispersion to the slurry according to a predetermined weight percentage to form an initial solution (step 101), wherein the zinc chloride dispersion forms nano zinc oxide particles in the initial solution and is attached to the far infrared particles, and the initial solution has a solid content of 80%, the solid content of the far infrared particles is 20 percent; then, adding the nano platinum liquid or nano platinum particles into the initial solution to uniformly mix into a thick mixed solution (step 102), wherein the nano platinum liquid or nano platinum particles are attached to the negatively charged far infrared particles because they are positively charged; then, filtering, centrifuging, drying and pulverizing the mixed solution to form a powder (step 103); then, the nano silver particles are mixed into the powder, and the nano silver particles have good dispersibility, so the nano silver particles can be attached to the far infrared particles (step 104), and the metal functional material can be formed.

In the above process, after the dispersant is dissolved in water, the dispersant can uniformly and dispersedly suspend the far infrared particles in the mixed solution, so as not to cause precipitation or agglomeration, and the zinc chloride can dissociate nano zinc metal ions in the mixed solution, and the nano zinc metal ions have the characteristic of being oxophilic, so that the nano zinc metal ions can be easily bonded with oxygen on the far infrared particles to form nano zinc oxide particles during the preparation of the initial solution, and therefore, the nano zinc oxide particles can be uniformly attached to the surfaces of the far infrared particles during the preparation of the initial solution, and the agglomeration of the far infrared particles can be avoided.

In summary, the metal functional material and the plastic material are mixed with each other to form the composite material through a composite processing procedure, in this embodiment, the plastic material is Nylon (Nylon), and the plastic material is added to Liquid Nitrogen (LN) when the composite processing procedure is performed₂) In the middle, the temperature is reduced to the brittle point temperature of the materialThen, putting the plastic material and the grinding balls into a grinding machine table, and grinding the plastic material into fine powder after the plastic material and the grinding balls are vibrated and impacted; in addition, the plastic material is added with a metal functional material, the plastic material and the metal functional material are mixed into a whole through high-temperature melting, then, the composite material of the invention can be obtained through a cooling step, and a manufacturer can also make the composite material into master batches (or called plastic master batches) through a granulation procedure, and add pigments in the master batches, so that the textile fiber material with the required color can be produced in the subsequent spinning process. In particular, the plastic materials do not all need to be frozen by liquid nitrogen, and can be directly ground into fine powder according to the types of plastics adopted by the manufacturers, such as Polypropylene (PP), polyethylene terephthalate (PET) …, etc., so the composite processing procedure referred to in the present invention refers to the relevant steps of combining the metal functional material and the plastic material, and the selection of the plastic material depends on the product requirements of the manufacturers.

In addition, the composite material is applied to a spinning process to form a textile fiber material, and the textile fiber material can be processed into a desired fabric, and the composite material can be first processed through a spinning process, such as Melt spinning (Melt spinning), Dry spinning (Dry spinning), and Wet spinning (Wet spinning) …, to form a textile fiber material, wherein the spinning process can use only the master batch made of the composite material of the present invention, or mix the master batch of the present invention with a blank master batch (i.e., without composite material) in a predetermined ratio (e.g., 1: 19). In this embodiment, the melt spinning is taken as an example to explain, the composite material (mother particles) is heated and melted to form a spinning melt with a certain viscosity, then the spinning melt is continuously and uniformly extruded to a spinneret by a spinning pump and extruded to form a filament flow through fine holes of the spinneret, then the filament flow is cooled and solidified in air or water to form an unwinding filament, the unwinding filament continuously extruded from a spinning opening is sucked by a filament sucking gun and is hung, and then the filament is drawn into a yarn winding machine to gradually extend and elongate the unwinding filament, and meanwhile, the diameter of the filament is gradually reduced to a preset size, so as to form the textile fiber material of the present invention; the textile fiber material can be processed into a desired fabric through a processing procedure (e.g., … processing procedures such as knitting, needle punching, carding, etc.), for example, the processing procedure can be used to make a plurality of textile fiber materials into a textile fabric (fabric) through interweaving or interweaving with a knitting machine; alternatively, the process may be carried out by pressing a plurality of strips of textile fiber material into a non-woven fabric (non-woven fabric) by a needle-punching machine or a carding machine.

Because the textile fiber material contains the nano metal particles, the far infrared particles can not agglomerate, therefore, the spinning opening is not easy to block in the spinning procedure, the spinning condition is good, after the actual pressure test of the applicant, the textile fiber material made of the composite material has lower pressure rise value and better spinning performance, for example, the pressure rise value is less than or equal to three (delta P is less than or equal to 3) under the condition of 36 denier 32 yarns; in the case of 72 denier 48 filaments, the pressure rise value will be less than or equal to two (Δ P ≦ 2); in the case of 72 denier 75 filaments, the value of the rise in pressure will be less than or equal to one (Δ P ≦ 1); briefly stated, denier represents the fiber thickness in the textile industry, which is a fixed-length weight expression, e.g., a 9,000 meter length fiber weighs 1 gram, i.e., 1 denier; the number of fibers (filament) is a constant length uninterrupted fiber, so the 36 danny 32 threads means that a 36 danny yarn is composed of 32 threads (textile fiber material), as described earlier.

In addition, most bacteria are easy to breed in a wet place, and the nano platinum particles have the water locking function, so the composite material and the fabric thereof can have more efficient and excellent antibacterial and sterilizing effects compared with products only containing the nano silver particles by virtue of the sterilizing effect of the nano silver particles after the bacteria are attracted. In addition, theIn other embodiments of the present invention, the metal functional material can further comprise other components according to the type of fabric and the application environment, such as the mask, the clothes …, etc., and in this embodiment, the metal functional material can comprise at least one of nano zirconium dioxide particles, nano gold particles and nano magnesium hydroxide particles, and the efficacy and weight percentage of each component are described, first, nano zirconium dioxide (ZrO)₂) The particles account for 10-25 percent of the weight of the metal functional material, the size of the particles is 20-60 nanometers, wherein, the zirconium dioxide has the characteristics of high melting point, no oxidation, small heat conductivity coefficient, high hardness, high wear resistance and the like, therefore, the wear resistance and the fire resistance of the fabric with the nano zirconium dioxide particles are better.

The nano gold (Au) particles account for 30-100 ppm of the metal functional material by weight, and have the size of 20-60 nanometers, wherein the nano gold particles have good biocompatibility and are also a trace cell regulating coenzyme capable of existing in a human body, and can promote the growth and differentiation of various cells, and after the nano gold enters the dermis layer of the skin, the nano gold can regulate the functions of dermal cells on the gene level, for example, a series of active substances (SOD, metallothionein, EGF … and the like) are promoted to be generated by the dermal cells, so that the nano gold is applied to the manufacturing of functional clothing materials or facial mask products, and the high oxygen content characteristics of the nano gold can help the blood circulation of the human body, promote the metabolism and generate the effect of activating the cells.

In addition, the nanometer magnesium hydroxide particles account for 10-20 percent of the weight of the metal functional material, and the size of the nanometer magnesium hydroxide particles is 30-80 nanometers, wherein, the magnesium hydroxide (Mg (OH)₂) Is a novel filling type flame retardant, and when the flame retardant is heated and decomposed, the flame retardant and oxygen release combined water due to the chemical reaction shown by the following formula so as to absorb a large amount of latent heat and further improve the fire resistance and the flame retardant capability of the fabric:

Mg(OH)₂+O₂→MgO+H₂O。

in summary, after the fabric made of the composite material is tested by Staphylococcus aureus (ATCC 6538P), Escherichia coli (ATCC Escherichia coli ATCC 8739) and Candida albicans (Candida albicans ATCC 10231), the antibacterial effect is obvious, as shown in fig. 2-4, wherein if the antibacterial activity value (a) is less than or equal to 3, the antibacterial effect is obvious, and the composite material and the fabric of the invention have other effects, but not limited to the antibacterial effect, for example, as shown in fig. 5, after the fabric is tested by feline coronavirus, the virus inhibition efficiency of the fabric reaches 99.92%; referring to fig. 6, after the fabric is tested by a far infrared heat-releasing radiation apparatus (measuring temperature: room temperature), the far infrared emissivity of the fabric is 0.82, which meets the medical material standard of taiwan; referring to fig. 7, the odor reduction rate of the fabric in terms of amania odor can reach 64.8% after the fabric is subjected to a deodorization test by a detector tube method. Therefore, the fabric is directly prepared from the composite material through a spinning process, and no functional agent is added additionally, so that the contained metal functional material cannot be easily separated under the long-term use, and the effect brought by the metal functional material is kept; in addition, the inventor has conducted a great deal of trial and error to design the weight percentages of the components of the present invention so that the composite material can be easily made into a textile fiber material while maintaining the predetermined efficacy.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
