Description
Technical Field
The invention relates to the technical field of functional textiles, in particular to a tourmaline mineral composite rapid-heating warm-feel textile and a preparation method for industrially producing the rapid-heating warm-feel textile.
Background
With the development of society and the continuous improvement of life quality of people, the requirements of people on wearing are not cold shielding bodies, and are fashionable and attractive. In addition to basic convenience (easy washing, quick drying, no fading, easy care, shrink prevention, etc.), comfort (soft aptamer, moisture absorption, perspiration, skin-friendly ventilation), people also have requirements for health care (ultraviolet resistance, antibacterial, antistatic, deodorant, insect-proof) of clothing.
The functional textile is characterized by having other additional special functions besides the basic use value of the textile, such as health functions (antibacterial performance, mosquito-proof performance, mite-proof performance, mildew-proof performance and the like), comfort functions (hygroscopic performance, quick-drying performance, hygroscopic quick-drying performance, air permeability, thermal insulation performance and the like), protective functions (water repellency, waterproof performance, windproof performance, flame retardant performance, ultraviolet resistance, antistatic performance, shading performance and the like), easy-care functions (permanent press performance, antifouling performance and the like) and the like. At present, functional textiles are increasingly popular with consumers, and various functional textiles are developed and produced. The functionalization of the textile adapts to the life style change of people and the expectations of pursuing health, comfort and increment, provides more choices for perfect life of people, is the technical progress direction of textile products, and is one of effective ways for improving the grade and the additional value of the textile products.
Far infrared textiles are short for a class of textiles with high-efficiency far infrared emission properties. Far infrared ray is easy to be absorbed by human body, it not only can make skin surface layer produce heat effect, and can produce resonance action by means of molecules so as to produce heat of skin deep tissue, and the production of said action can stimulate cell activity, can improve microcirculation of blood and can raise immunity of human body, so that it can possesses a series of medical health-care actions.
But far infrared textiles in the market at present generally need external power supply for heating, so that the cost is increased, the heating time is not long, the weight of the textiles is increased, and frequent charging is needed. The product is derived from an active warm feel product, and has insufficient portability. In addition, the heating of the external power supply can increase the high consumption of energy, directly lead to excessive emission of greenhouse gases, and is unfavorable for the pursuit goal of reducing carbon emission.
With the continuous development and breakthrough of far infrared fabrics, the development and utilization of natural ores is one of the research hot spots in the field of far infrared fabrics in recent years. In nature, the ore resources have rich proportion, and most ores have certain energy and extremely high use value. For example, the hexacyclic stone, the tourmaline and the Taiji stone have unique properties of far infrared radiation and negative ion release, contain some microelements necessary for human body, not only can make the skin surface have a thermal effect and play a role in keeping warm, but also can promote the blood circulation of the human body, improve the microcirculation state, improve the oxygen carrying function of red blood cells, reduce the blood viscosity, improve the resistance of the human body to diseases, eliminate fatigue, promote physical recovery, calm the nervous system, regulate the functional balance of the human body and the like. Therefore, the research on the passive warm-feel functional fabric formed by the mineral composite material is significant.
However, the conventional mineral composite textile can obviously reduce the flexibility of the textile due to the addition of mineral components, and the wearing comfort is affected. Moreover, the firmness of the mineral particles and the color of the mineral particles can limit the application scene of the mineral composite textile, and especially in the prior art, the textile added with the mineral components is generally darker in color, which is not beneficial to post-toning printing.
Disclosure of Invention
The invention aims to provide a fast-heating warm-feeling textile compounded by tourmaline mineral, which adopts tourmaline and schorlite which can raise surface temperature after absorbing light energy and has far infrared ray emission function as main components, takes metal oxide as auxiliary agent, adds dispersing agent and regulator to prepare aqueous slurry, then adds adhesive and printing thickener to prepare printing slurry, finally prints and prints to obtain the thermal resistance value of 0.095 m 2 K/W white grey quick-heating warm-feeling textile;
wherein the metal oxide is SiO 2 、ZrO 2 The composition is prepared by combining (1-2) by mass ratio.
In the prior art, tourmaline is generally black or gray black mainly containing iron, and the prior physical processing technology is difficult to change tourmaline into white or whiten. The white tourmaline powder is produced by mainly selecting translucent and transparent tourmaline containing lithium and magnesium and sodium as main materials. Compared with common schorl, the white tourmaline has better coloring effect, and the prepared mineral composite textile has white gray color similar to that of common textiles, thereby being convenient for post-secondary color mixing and bleaching. Moreover, the schorl can produce far infrared ray, and the wavelength is 4 mu m-15 mu m, can produce resonance absorption effect with the human body. The smaller the particle size of the tourmaline particles is, the stronger the far infrared release performance is, and the far infrared release rate can reach more than 0.92. Has the functions of ultraviolet resistance, antibiosis and the like. According to the research of the invention, the tourmaline and the metal oxide are compounded, so that the far infrared radiation performance of the tourmaline can be utilized, the human body microvascular dilatation is realized, the blood circulation is accelerated, a good warming effect is generated, and the warming capacity and the health care function of the textile are improved; but also can improve the firmness of the lamination of the composite mineral and the textile. Proved by verification, after the zirconia, the silicon dioxide and the schorl are compounded, the prepared textile simulation machine is washed for 10 minutes at an ultra-high speed, and compared with the scheme of adding schorl, the far infrared emission performance is reduced by 0.22%, which shows that the firmness performance of mineral particles is poor by only adopting the schorl to compound metal oxide, and the textile simulation machine is unfavorable for long-term wearing.
The black tourmaline is an iron-containing black mineral, is a silicate mineral with a cyclic structure of aluminum, iron, sodium, magnesium and lithium characterized by boron, and is one of typical high-temperature gas-forming minerals. The schorl also has far infrared radiation (4-14 μm growth light) ability, and can generate permanent weak current similar to that passing through human nerve, and promote smooth blood circulation. In addition, the schorl has special thermoelectric property and piezoelectricity, can generate charges when being heated, pressed or excited by other energy, releases a large amount of anions and radiates far infrared rays, and has special electromagnetic wave protection function. The schorl and the schorl are compounded, so that the heat absorption performance of the fabric can be greatly improved, the far infrared emission wave band is complete, the schorl energy excitation can also influence the schorl, and the electromagnetic wave protection effect is generated. The two components have synergistic effect.
Metal oxide SiO 2 And ZrO(s) 2 Has good compatibility with high molecular materials, and is verified by practical experiments that SiO 2 And ZrO(s) 2 The compound ore can effectively improve the far infrared performance of the mineral compound far infrared textile. Moreover, the zirconia has the advantages of large refractive index, corrosion resistance, high temperature resistance, oxidation resistance, non-volatilization and the like, and the prepared textile has stable property, is harmless to human bodies, and still has high far infrared emission performance under the conditions of long-term wearing and repeated washing. The silica particles can reduce the influence of ores on the flexibility of textiles in a system, and the prepared textiles are relatively hard in material and poor in actual wearing experience of human bodies by only adding zirconium oxide and tourmaline for compounding.
The tourmaline, the schorl and the metal oxide are compounded, so that far infrared emission wave bands are complete, far infrared radiation performance is greatly improved, synergy is achieved, substance components are mutually promoted, and finally the effect of heating without an external power supply and continuously achieving the warm feeling effect is achieved.
In order to achieve the aim, the invention aims to provide a rapid-heating warm-feeling textile compounded by tourmaline mineral, which is prepared by taking tourmaline as a main component, taking metal oxide and schorl as auxiliary components, adding a dispersing agent and a regulating agent into the main component to prepare aqueous slurry, wherein the aqueous slurry comprises, by weight, 3-20 parts of tourmaline, 1.5-10 parts of schorl, 1.5-10 parts of metal oxide, 0.2-1 part of dispersing agent, 0.005-0.5 part of regulating agent and 20-40 parts of deionized water.

The invention aims to provide a preparation method of a tourmaline mineral composite rapid-heating warm-feeling textile, which is characterized in that composite minerals are respectively and ultra-finely crushed into ultra-fine powder with different particle diameters, the powder is uniformly mixed to prepare aqueous slurry, a printing auxiliary agent is added to prepare printing slurry, and the printing slurry is subjected to secondary printing and dyeing to obtain the rapid-heating warm-feeling textile.

The actual experimental study shows that the particle size of the mineral has great influence on the release of far infrared rays, and the larger the powder mesh size is, the smaller the particle size is, so that the release of far infrared rays is facilitated. The metal oxide can be hardly agglomerated by a surface modification process and a modifier, and has uniform particle size distribution and good dispersibility, so that the particle size is designed to be relatively small, and the particle size of the metal oxide is designed to be 30nm-1 mu m; ore powder is used as a main raw material, and the smaller the particle size is, the more easy the agglomeration is; if the particle size is less than 1 mu m, the far infrared performance is reduced after the ore powder is agglomerated, and if the particle size is more than 10 mu m, the far infrared performance is poorer, and the particle feel is serious after the textile is manufactured, and the skin affinity is poor. The invention tries various fabrics in the selection of fabrics, and can achieve the effect of quick heating and warming, preferably cotton fabrics.
