Technical Field

The invention relates to the technical field of functional textiles, in particular to a white tourmaline mineral composite quick-heating warm-feeling textile and a preparation method for industrially producing the quick-heating warm-feeling textile.

Background

With the social development and the continuous improvement of the life quality of people, the requirements of people on wearing are not only cold shielding bodies but also fashionable and beautiful. Besides basic convenience (easy washing, quick drying, no fading, no ironing, shrink prevention and the like), comfort (soft aptamer, moisture absorption and perspiration, skin-friendly and breathable), people also have requirements on health care of clothing (ultraviolet resistance, antibiosis, antistatic property, deodorization and insect prevention).

The functional textile has other additional special functions besides the basic use value of the textile, such as health functions (antibacterial property, mosquito-proof property, mite-proof property, mildew-proof property and the like), comfort functions (moisture absorption property, quick drying property, moisture absorption quick drying property, air permeability, heat preservation property and the like), protection functions (water repellency, waterproof property, windproof property, flame retardant property, ultraviolet-proof property, antistatic property, shading property and the like), easy-care functions (non-ironing property, antifouling property and the like) and the like. At present, functional textiles are more and more popular with consumers, and various functional textiles are developed and produced. The functionalization of the textile is suitable for the change of life style of people and the expectation of pursuing health, comfort and value increase, provides more choices for perfect life of people, is the direction of the technical progress of textile products, and is one of effective ways for improving the grade and the added value of the textile products.

Far infrared textiles are short for textiles with efficient far infrared emission performance. The far infrared ray is easy to be absorbed by human body, it not only makes the skin surface layer produce heat effect to play the warm-keeping effect, but also produces resonance effect through molecules to cause the skin deep tissue to generate heat, the generation of this effect can stimulate cell activity, improve the microcirculation of blood, improve the immunity of organism, play a series of medical care effects.

However, far infrared textiles in the current market generally need to be heated by an external power supply, so that the cost is increased, the heating time is short, the weight of the textiles is increased, and frequent charging is needed. The products are derived from active warming products and are not portable. Moreover, the external power supply also increases the high energy consumption, directly causes excessive emission of greenhouse gases, and is not beneficial to the pursuit of reducing carbon emission.

With the continuous new development and breakthrough of far infrared fabrics, the development and utilization of natural ores are one of the research hotspots in the field of far infrared fabrics in recent years. In nature, the ore resources are rich, and most of ores have certain energy and extremely high use value. For example, the six-ring stone, the tourmaline, and the taiji stone have unique properties of far infrared radiation and negative ion release, contain some trace elements necessary for human body, not only can make the skin surface have thermal effect and play a role in keeping warm, but also can promote blood circulation of human body, improve microcirculation state, improve oxygen carrying function of red blood cells, reduce blood viscosity, improve resistance of human body to diseases, eliminate fatigue, promote physical recovery, calm nervous system, regulate body function balance, and the like. Therefore, the research on the passive warm-feeling functional fabric made of the mineral composite material is significant.

However, the conventional mineral composite material textile is added with mineral components, so that the flexibility of the textile is obviously reduced, and the wearing comfort is affected. Moreover, the firmness and 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 mineral components has a dark color generally, which is not beneficial to the later-stage color-mixing printing.

Disclosure of Invention

The invention aims to provide a white tourmaline mineral composite fast-heating warm feeling textile which adopts white tourmaline and black tourmaline which can increase the surface temperature and have the far infrared ray emission function after absorbing light energy as main components, takes metal oxide as an auxiliary agent, adds a dispersing agent and a regulator to prepare aqueous slurry, adds an adhesive and a printing thickening agent to prepare printing slurry, and finally prints and dyes to obtain the textile with the thermal resistance value of 0.095m²K/W white gray quick-heating warm feeling textile;

wherein the metal oxide is SiO₂、ZrO₂The components are combined according to the mass ratio of 1 (1-2).

In the prior art, the tourmaline is generally black or gray black mainly containing iron, and the existing physical processing technology is difficult to whiten or whiten the tourmaline. The white tourmaline powder is produced by mainly using translucent and transparent tourmaline which mainly contains lithium, magnesium and sodium. Compared with common black tourmaline, the white tourmaline has better coloring effect, and the prepared mineral composite textile has white gray color, is similar to the color of a common textile, and is convenient for secondary color mixing bleaching and dyeing in later period. Furthermore, the tourmaline can generate far infrared ray with wavelength of 4-15 μm, and can generate resonance absorption effect with human body. The smaller the particle size of the tourmaline particles is, the stronger the far infrared releasing performance of the tourmaline particles is, and the far infrared releasing rate can reach more than 0.92. Has the functions of resisting ultraviolet rays, resisting bacteria and the like. The research of the invention finds that the compounding of the leucolite and the metal oxide can utilize the far infrared radiation performance of the leucolite to expand human body microvasculature, accelerate blood circulation, generate good warming effect, and improve the warming ability and the health care function of textiles; but also can improve the bonding firmness of the composite mineral and the textile. According to verification, after the prepared textile is washed for 10 minutes at ultrahigh speed by a simulation machine only by compounding the zirconium oxide, the silicon dioxide and the black tourmaline, the far infrared emission performance is reduced by 0.22 percent compared with the scheme of adding the white tourmaline, which shows that the firmness performance of mineral particles is poor and the textile is not beneficial to long-term wearing and use only by compounding the black tourmaline and the metal oxide.

The schorl is a ferrous black mineral, is a silicate mineral with a ring structure of aluminum, iron, sodium, magnesium and lithium which is characterized by containing boron, and is one of typical high-temperature gas-forming minerals. The black tourmaline also has the ability of emitting far infrared radiation (4-14 μm of growing light), can generate permanent weak current, and is similar to current passing through human nerve, and can promote blood circulation to be smooth. Moreover, the schorl has special pyroelectricity and piezoelectricity, generates electric charges when being heated, pressed or excited by other energy, releases a large amount of negative ions and radiates far infrared rays, and has a special electromagnetic wave protection function. The black tourmaline and the white tourmaline are compounded, so that the heat absorption performance of the fabric can be greatly improved, the far infrared emission wave band is complete, the black tourmaline can be influenced by the excitation of the energy of the white tourmaline, and the electromagnetic wave protection effect is generated. The two are compounded to have a synergistic effect.

Metal oxide SiO₂And ZrO₂Has good compatibility with high polymer materials, and is verified by practical experiments to be SiO₂And ZrO₂The far infrared performance of the mineral composite far infrared textile can be effectively improved by compounding the minerals. Moreover, the zirconium oxide has the advantages of large refractive index, corrosion resistance, high temperature resistance, oxidation resistance, non-volatility and the like, and the prepared textile has stable property and no harm to human bodies, and still has high far infrared emission performance under the conditions of long-term wearing and repeated washing. The silicon dioxide particles can reduce the ore content in the systemThe influence of stone on the flexibility of the textile is verified, and only the zirconia, the white tourmaline and the black tourmaline are added for compounding, so that the prepared textile is relatively hard, and the actual wearing experience of a human body is poor.

Compounding the white tourmaline, the black tourmaline and the metal oxide, the far infrared emission band can be complete, the far infrared radiation performance can be greatly improved, the synergistic effect can be realized, the material components are mutually promoted, and finally the effect of breaking away from an external power supply to heat and continuously achieving the warm feeling effect can be achieved.

In order to achieve the purpose, the invention aims to provide a white tourmaline mineral composite fast-heating warm-feeling textile, which is prepared by taking white tourmaline as a main component, taking metal oxide and black tourmaline as auxiliary components, and adding a dispersant and a regulator into an aqueous slurry, wherein the aqueous slurry comprises, by weight, 3-20 parts of white tourmaline, 1.5-10 parts of black tourmaline, 1.5-10 parts of metal oxide, 0.2-1 part of dispersant, 0.005-0.5 part of regulator and 20-40 parts of deionized water.

In a preferred embodiment, the dispersant is a polyacrylic ammonium salt dispersant, and the regulator is AMP-95, wherein the AMP-95 is 2-amino-2-methyl-1-propanol, and is used for stabilizing the pH value of the system under the condition and has the functions of wetting and dispersing; when the dispersant is used with a polyacrylic acid ammonium salt dispersant, the dosage of the dispersant can be reduced, and the dispersing effect is improved; the printing thickener is compounded with the printing thickener, so that the performance of the thickener can be improved, ammonia water is not needed, and pollution and smell are reduced.

The invention aims to provide a preparation method of a white tourmaline mineral composite quick-heating warm-feeling textile.

The actual experimental research shows that the mineral particle size has great influence on the release of far infrared rays, and the larger the powder mesh is, the smaller the particle size is, the more favorable the release of the far infrared rays is. The metal oxide can be difficult to agglomerate through a surface modification process and a modifier, the particle size distribution is uniform, the dispersity is good, so 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; the ore powder is used as a main raw material, and the smaller the particle size, the more easy the ore powder is to agglomerate; if the particle size of the ore powder is less than 1 μm, the far infrared performance is reduced, and if the particle size is more than 10 μm, the far infrared performance is poor, and the prepared textile has serious granular feeling and poor skin-friendly performance. The invention discloses selection of fabrics in textiles, various fabrics are tried, the effect of quick heating and warming can be achieved, and cotton fabrics are preferred.

In a preferred embodiment, in step S3, the mass ratio of the binder, the thickener and the aqueous slurry is (10-30): (30-50): (20-60).
