Description

The invention belongs to functional textiles. It is suitable for knitting various fabrics such as underwear, panties, knee pads, socks and waist pads for human body.

In the prior art, in response to people's awareness of health care and the need to treat some common chronic diseases, some instruments or human bodies have been developed that have biological functions such as enhancing human blood circulation, improving microcirculation blood flow, and can enhance physical fitness and eliminate diseases. attachments, etc.

Japanese patent JP03137213 provides a kind of function, and it is to contain fine ceramic powder in a kind of special fiber. This material reflects far-infrared rays and has functions such as far-infrared radiation, anti-corrosion, heat conduction protection, and deodorization. The particle size of the ceramic powder is less than 100 microns. However, far-infrared rays can only play a role under the condition of a heat source, and the use is limited; in addition, the ceramic powder has a large particle size, and its fiber strength is low, and the finished product is also limited.

The EP-331160 patent also provides a functional material, which is composed of carbides, oxides, nitrides, and oxygen-hydrides of elements such as Ti, Zr, V, Nb, Ta, Cr, Ce, Co, and Mn. one or more components. In the form of fibers or particles, the material has piezoelectricity, electron emission, biological properties and magnetic properties. It can be used in capacitors, piezoelectric bodies, catalysts, multilayer circuit boards, artificial bones, etc. However, this material is difficult to make into textiles, and its use is limited.

The purpose of the present invention is to provide a functional textile that can promote, regulate and improve the superficial blood microcirculation of human skin and improve the relative blood flow of the skin and its manufacturing method.

In order to achieve the above object, the main technical solution adopted by the present invention is to contain a complex oxide ceramic material in the composition of the textile. After the ceramic is pulverized, each particle has permanent electricity, piezoelectricity and pyroelectricity. Mix this kind of ceramic powder with special properties with viscose (Rayon) to make viscose cotton, and further make functional viscose fiber; the functional viscose fiber is mixed with cotton yarn, polyester yarn, nylon yarn and polyurethane yarn Any one or two or more are woven into textiles. This kind of textile is used to make underwear, underwear, etc. of the human body for people to use.

That is to say, the functional textile of the present invention is composed of functional viscose fiber and any one or more of cotton yarn, polyester yarn, nylon yarn and spun yarn, and its specific composition (weight %) is as follows:

The functional viscose fiber is 40-60%; the sum of any one or two or more of cotton yarn, polyester yarn, nylon yarn, and polyurethane yarn is 60-40%.

In functional viscose fiber, its composition (weight %) is:

Functional ceramic powder 1-10%, viscose 90-99%;

The particle size of the functional ceramic powder is <0.5 μm.

The composition (weight %) of this functional ceramic powder is:

SiO ₂ 35～37%, Al ₂ O ₃ 29～34%, B ₂ O ₃ 9～11%, FeO 5～15, MgO 5～8%, Na ₂ O 1.5～3%, TiO ₂ 0.5～1.5% , CaO 0.5-1.5%, K ₂ O 0.001-0.05%, MnO 0.001-0.05%.

As can be seen from the above, the functional ceramic powder in the textile raw material of the present invention is a complex oxide, which has permanent electricity, pyroelectricity and piezoelectricity. Therefore, the textile also has the same performance. It can electrolyze water and make sulfuric acid The copper solution changes color; the sanitary inspection shows that the textile is non-toxic, odorless and non-polluting.

The functional textile of the invention can promote, improve and regulate human blood circulation, increase the relative blood flow of microvessels, and achieve health care and treatment effects. Its working principle is as follows:

Because the functional textile of the present invention has permanent electricity, piezoelectricity and pyroelectricity, when fabrics such as underwear and panties woven from it are wrapped on the surface of human skin, the microelectrodes of the textile act on the surface of the skin to form a weak electric field. , produce a weak current, stimulate the human skin and certain acupoints, stimulate the capillaries, reticular nerves or sensory cells of the skin under the human epidermis, so that they are charged. This effect can enhance the blood circulation of the skin, and transmit this effect to the central nervous system to generate reflections, further dilate the microvessels, and increase the blood flow of the microcirculation. Acupoints, and one end of the acupoints is connected to the central nervous system through nerves and leads to the brain. That is, the micro-electric field felt by the acupuncture points is converted into an "electrical signal", which changes the inner and outer potentials of the nerve cell membrane, that is, the formation of nerve excitement or stimulation, and transmits it to the brain, so that the autonomic nerves intervene to achieve the function of regulating human body functions.

On the other hand, when the micro-current formed on the skin surface flows through the skin surface, Joule heat is generated due to the resistance on the skin surface, which increases the temperature of the skin surface and the human body feels warm. When the temperature of the skin surface rises to a certain level, due to the sufficient improvement of the micro-blood circulation, the evaporation speed of the human body surface is accelerated, so that it has a cool feeling.

The manufacture method of functional textile of the present invention is as follows:

The specific steps of the manufacturing method are as follows: (1) preparation of functional ceramic powder; (2) production of viscose cotton and functional viscose fiber from functional ceramic powder and viscose; (3) production of functional textiles from functional viscose fiber and cotton yarn. Now it is described as follows:
