Moreover, unlike animal and plant fibers, taiji stone fibers inherit the natural antibacterial effect of mineral fibers well. As disclosed in patent CN108330553a, a preparation method of taiji stone cellulose fiber is disclosed, a taiji stone suspension with far infrared, anti-ultraviolet and antibacterial functions is uniformly mixed with cellulose sulfonate solution through injection before spinning, and a finished product is obtained through wet spinning and post-treatment.

The Taiji stone cellulose fiber not only has excellent far infrared function, ultraviolet resistance and bacteriostasis, but also has the functions of relieving depression and improving sleep, has higher breaking strength and elongation at break, and has lasting and stable performance, mature process, simple flow, easy control and contribution to industrial production. From the health point of view, the Taiji stone fiber fabric is a healthy, safe and comfortable choice. However, the fabric made of the single-component Taiji stone fiber has poor functionality and skin-friendly property, and the user experience is poor. There is a need for an ideal solution.
Disclosure of Invention
In order to overcome the problems of poor functionality and poor skin-friendly performance of the Taiji stone fiber, the fabric containing the Taiji stone fiber is provided, and the fabric has the softness, moisture absorption and sweat release properties, stiffness and far infrared functions of the Modal fiber and improves wearing comfort through the specification of the fabric and the selection and matching of materials.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
the fabric comprises warp yarns and weft yarns, wherein the warp yarns are formed by blending Modal fibers and Taiji stone fibers taking viscose fibers as carriers; the weft yarns are two, wherein the weft yarn I is formed by blending Modal fibers and Taiji stone fibers taking viscose fibers as carriers, and then the yarn is coated with elastic yarns, and the weft yarn II is formed by twisting spandex yarns and Taiji stone fiber filaments taking nylon as carriers.
Preferably, the mass ratio of the modal fiber to the Taiji stone fiber in the warp yarn is (60-70): (30-40), and the mass ratio of the modal fiber, the Taiji stone fiber and the stretch yarn in the weft yarn I is (40-50): (20-30): (30-35). The elastic yarn is preferably a fabric formed by mixing polyester fibers and spandex.
Preferably, the fabric adopts warp double structures, the first weft yarn and the warp yarn are woven into an inner layer of the fabric, the second weft yarn and the warp yarn are woven into an outer layer of the fabric, and the first weft yarn and the second weft yarn are woven into the fabric according to the proportion of 1:1. The fabric contains the raw materials of the Taiji stone fiber components, the effect of the Taiji stone fibers is exerted, and the Taiji stone fiber machine-wrapped filaments are adopted on the surface of the fabric, so that the function of the Taiji stone fibers can be considered, and the gloss, the hand feeling, the wear resistance and the effective crease resistance and the drapability can be maintained.
The Taiji stone has excellent far infrared function, can generate resonance effect with water molecules in human cells, strengthen the kinetic energy of blood cells, refine the water molecules, promote the microcirculation of human blood, and has certain health care effect on relieving joint ache and the like, but the Taiji stone fiber has high cost and poor skin affinity. The modal fiber has good softness, moisture absorption and perspiration but poor fabric stiffness, and the fabric has the softness of the modal fiber and the stiffness of the Taiji stone fiber at the same time by selecting and matching the specification of the fabric tissue and the materials. The weft yarns are woven through a certain proportion of structural arrangement, so that the Taiji stone fibers cut the skin better, and the effects of promoting microcirculation, resisting bacteria and resisting fatigue are achieved by being effectively combined with a human body. The Modal fiber has good moisture absorption and sweat release functions, so that sweat generated by a human body due to the heating of Taiji stone is timely discharged, and the wearing comfort level is improved.
Preferably, the preparation method of the Taiji stone fiber comprises the following steps: fully mixing the Taiji stone particles and viscose fiber master batches or nylon master batches according to the mass ratio of (1-5): 100, and carrying out melt extrusion, cooling, winding and forming to obtain the Taiji stone fiber. From microstructure, the prepared Taiji stone fiber is in a core-spun structure, a groove is formed in the middle of the fiber, small black points are formed on the fiber, taiji stone is in an embedded state in the fiber in a blending mode, the Taiji stone fiber is not easy to run off, and the structure is stable. The dosage proportion of the Taiji stone and the master batch needs to be reasonably controlled, the Taiji stone is less in dosage and easy to be buried, the far infrared function is affected, the Taiji stone is more in dosage and difficult to disperse uniformly, and the cost can be increased.
As a further preference, the melting temperature is 300-350℃and the extrusion pressure is 10-20MPa.
Preferably, the particles of the Taiji stone fiber have a particle diameter of 0.8-1 μm, a surface roughness of 0.015-0.02 μm and a porosity of 10-13%. Wherein the surface roughness is measured by scattering, the porosity measurement method is referred to (Ling Zhenbao et al, "rock ore porosity measurement method" university journal: earth science edition 41.3 (2011): 4). The water molecules of human cells have a fixed frequency (8-15 μm). According to the principle that two identical sound waves or two identical light waves meet to generate resonance in physics, far infrared rays generate resonance absorption phenomenon with water molecules in human tissue cells through skin and subcutaneous tissues, so that the immunity can be improved, and the human health is promoted. The normal body temperature of human body is about 37 ℃, and the wavelength peak value of the generated electromagnetic wave is about 9.5 μm. The far infrared action wavelength of the Taiji stone is 3.9-16 mu m, and the wavelength is regulated to 8-15 mu m, so that the Taiji stone can generate resonance with human cells at maximum efficiency, and promote metabolism. The wavelength is affected by the propagation medium, so the particle size, surface roughness and dispersion state of the taiji stone in the master batch all have an influence on the wavelength. Experiments show that the Taiji stone particles have wavelengths within the characteristic range which meet the requirements of human bodies.
Preferably, the preparation method of the Taiji stone particles in the Taiji stone fiber comprises the following steps: crushing raw ore, grinding into powder, adding mixed solution of HF and concentrated nitric acid with volume ratio of 1 (80-100), reacting for 5-10min under microwave condition of 30-40MPa and 100-120 deg.C, wherein the dosage ratio of raw ore and mixed solution is 1g (15-17) mL. The Taiji stone has hard particle structure, the internal structure is difficult to change by conventional acid treatment and calcination treatment, and the inventor discovers that HF and concentrated nitric acid can destroy silicon oxide tetrahedron [ SiO ] of silicon dioxide in the Taiji stone under the microwave condition 4 ]The structure improves the porosity of the Taiji stone, and the high porosity can form a cavity effect, so that the emissivity of far infrared energy is improved, and the heating effect of the Taiji stone is improved. Of course, the mixed acid can generate nicks or cracks on the surface of the Taiji stone, so that the surface roughness is improved, and the improvement of the roughness is also beneficial to the improvement of emissivity.
Therefore, the invention has the beneficial effects that: (1) Through the selection and collocation of the fabric tissue specification and the materials, the fabric has the softness, the moisture absorption and sweat release properties of the Modal fibers, the stiffness and the far infrared functions of the Taiji stone fibers, and the wearing comfort level is improved; (2) Limiting the particle size and the surface roughness of the Taiji stone and the addition amount of the Taiji stone in the master batch, regulating and controlling the far infrared wavelength and emissivity of the Taiji stone, and improving the body-building efficacy of the Taiji stone.
