Description

Heating health-care composite textile and preparation method thereof
Technical Field
The invention relates to the technical field of functional textiles, in particular to a heating health-care composite textile and a preparation method thereof.
Background
With the progress of science and technology, people have higher and higher requirements on clothes, and particularly, thermal textiles for keeping the temperature of a human body are greatly developed. Some field soldiers working outdoors for a long time, geological prospecting personnel, traffic managers, security guards and the like all need cold-proof and warm-keeping textiles to keep warm. In addition, the elderly, such as the elderly with poor health, need to keep warm and keep healthy. Therefore, it is important to research lightweight and thin thermal textiles.
The traditional warm keeping and cold protection mainly adopts thicker cotton clothes, down coats and the like to achieve the effect of resisting cold, but the passive cold protection is not enough to resist low temperature in extreme cold days as long as the heat of a human body of a house is dissipated. And too bulky cold protective clothing makes work very inconvenient. In recent years, with the development of high-performance thermal materials such as carbon fiber and graphene, active heating is rapidly applied and developed to textiles. The flexibility and collapsibility of carbon fibers and graphene allow for use in textiles, but are extremely inconvenient to use due to the need for heating.
The far infrared refers to electromagnetic waves with the wavelength range of 4-1000 mu m, the material with the far infrared performance can absorb the electromagnetic waves emitted by the environment or human body and radiate far infrared rays with the wavelength range of 2.5-30 mu m, and the far infrared rays are overlapped with the absorption wavelength of 6-14 mu m of human body moisture, so that a resonance effect is generated, and molecular vibration generates heat energy to enable people to feel warm. The research on materials for far infrared properties is now becoming mature. Has great potential for the textile field. The far infrared fiber textile is a textile with the functions of absorbing and emitting far infrared rays at normal temperature, is prepared by adding far infrared ceramic powder in the fiber processing process, is a positive and efficient heat insulation material, and simultaneously, the radiated far infrared rays also have the effects of activating cell tissues, promoting blood circulation, inhibiting bacteria and deodorizing. The textile prepared by utilizing the far infrared fibers is a functional textile for health care and cold resistance at present.
The textile prepared by using the ceramic powder with the far infrared radiation function for the fiber can be widely used for weaving bed sheets, quilt covers, pillow cases, clothes and the like, and has wide application market. In addition, the textile made of the far infrared fibers also has the functions of resisting ultraviolet rays, sterilizing, eliminating peculiar smell, improving human microcirculation and the like, meets the general requirements of people on health and comfort at present, and has better commercial value and development prospect.
However, in order to fully exert the heating function of the far infrared material, the far infrared material needs to be uniformly dispersed in the textile and the interface needs to be fully exposed, however, the prior art compounds the far infrared material in the fiber, which affects the exposure of the interface; the coating is coated after being dispersed in the finishing agent, and because the far infrared material is in a micro-nano level, the coating is difficult to be uniformly dispersed and is not firmly attached.
Disclosure of Invention
The invention provides a heating health-care composite textile and a preparation method thereof, aiming at the problems that the far infrared heating effect is influenced because the existing far infrared nano ceramic powder is used as a heating material in a textile finishing agent and the far infrared heating effect is influenced because the far infrared nano ceramic powder is difficult to be firmly attached to the textile.
The invention relates to a preparation method of a heating health-care composite textile, which aims to ensure that far infrared nano ceramic powder is used as a heating material for a better exposed interface of a textile and can be well attached to the textile, the invention firstly dispersedly compounds the far infrared nano ceramic powder with graphene which is used as a material with high specific surface area, and the far infrared nano ceramic powder interface is fully exposed by isolation; the composite nylon is subjected to melt extrusion and biaxial stretching with the maximum magnification, so that the biaxial stretching magnification is increased as much as possible, and the far infrared nano ceramic powder is fully dispersed and exposed on an interface, thereby improving the heating performance of the composite nylon. After the microporous membrane is attached to a textile object, a plurality of groups of rollers are rolled to firmly attach the stretched microporous membrane to the textile; further sanding is carried out to ensure that the far infrared nano ceramic powder is fully dispersed and an interface is exposed. The method specifically comprises the following steps:
(1) dispersing infrared nano ceramic powder and graphene uniformly, then adding nylon for uniform dispersion, adding the mixture into a screw extruder for melt extrusion, and extruding the mixture into a film through a T-shaped die;
(2) carrying out hot biaxial stretching on the film obtained in the step (1) to obtain a microporous film, preheating the textile, and attaching the microporous film to the textile;
(3) and (3) pressing the bonding material obtained in the step (2) by a plurality of groups of continuous hot rollers, sanding and coiling to obtain the heating health-care composite textile.
Further, the far infrared nano ceramic powder in the step (1) is nano tourmaline powder. The tourmaline powder has piezoelectricity and pyroelectricity. The far infrared ray (the wavelength is 4-14 um) beneficial to human bodies is emitted, the metabolism is promoted, the heart pressure is reduced, and the health care pillow can also be used for conditioning and improving hypertension, cardiovascular and cerebrovascular diseases, tumors, arthritis, numbness of limbs, cold limbs, scapulohumeral periarthritis, pain of limb parts, lumbar disease strain, herniated disc deformation, cervical spondylosis and the like. It also has excellent prevention and adjuvant treatment effects on gastroenteropathy, kidney deficiency, and menoxenia.
Further, the particle size of the far infrared nano ceramic powder is 10-20 nm. The far infrared nano ceramic powder is white powder and is formed by mixing a plurality of substances. The far infrared ceramic powder has a main characteristic function of being capable of radiating far infrared rays (higher infrared radiance) more than that of a normal object. The absorption wavelengths of the far infrared nano ceramic powder and human body moisture are overlapped, so that a resonance effect is generated, molecular vibration generates heat energy, a person feels warm, and the far infrared nano ceramic powder is used for enabling polyester fibers to have a heating health-care effect.
The far infrared ray is used for human body health care: the activity of the biomacromolecule is activated, so that the molecule of the organism can be excited to be in a higher vibration state. Thus, the activated activity of large biological water molecules such as nucleic acid protein and the like is realized, so that the function of regulating activities such as organism metabolism, immunity and the like by large biological molecules is exerted, the recovery and the balance of functions are facilitated, the purposes of preventing and treating diseases are achieved, and the blood circulation is promoted and improved. After far infrared ray acts on skin, most energy is absorbed by skin, the absorbed energy is converted into heat energy to cause skin temperature to rise, a heat sensor in skin is stimulated, blood vessels are expanded through thalamus reflection, and blood circulation is accelerated. On the other hand, due to the heat effect, the release of vasoactive substances is caused, the blood vessel tension is low, the superficial arteriole, the superficial capillary and the superficial vein are expanded, the blood circulation is improved (detected by a blood disease research institute of Chinese medical academy of sciences) for 20 minutes, and the microcirculation blood flow volume can be improved by 114 percent. The metabolism is enhanced, if the metabolism of the human body is disordered to cause the abnormal exchange of substances in the body, various diseases such as water and electrolyte metabolism disorder can be caused, and the danger is brought to life; the development of diabetes caused by sugar metabolism disorder; hyperlipidemia and obesity caused by lipid metabolism disorder; disorders of protein metabolism cause gout and the like. By means of far infrared heat effect, cell activity can be increased, nerve fluid organism can be regulated, metabolism can be enhanced, and material exchange inside and outside the body can be in a stable state. Has anti-inflammatory and repercussive effects. The far infrared heat action activates immune cell function through the response reaction of nerve fluid, strengthens the phagocytic function of leucocyte and reticuloendothelial cell, and achieves the aim of diminishing inflammation and inhibiting bacteria. Has effects in enhancing tissue nutrition, activating tissue metabolism, increasing oxygen supply to cells, enhancing cell regeneration ability, improving blood oxygen supply state of affected area, controlling and limiting inflammation, and accelerating focus repair. The far infrared heat effect improves microcirculation, establishes collateral circulation, adjusts ion depth, promotes metabolism of toxic substances and waste excretion, accelerates absorption of exudative substances, and makes inflammatory edema disappear. Based on the above principle, far infrared energy has transferability from high to low, that is, energy can be transferred from a strong side to a weak side, so-called day's path loss has complementary deficiency, which is very important for adjusting energy balance of each organ of a human body, so that the far infrared energy is widely used in the fields of medical treatment and rehabilitation.
Further, in the step (1), the mass ratio of the far infrared nano ceramic powder to the graphene to the nylon is 20-30: 5-15: 100-120.
Further, the nylon in the step (1) is nylon 66; the melt extrusion temperature of the screw extruder is 220-230 ℃.
Further, the longitudinal stretching multiplying power of the bidirectional stretching in the step (2) is 15-20; the transverse stretching ratio is 10-15. The stretching ratio is increased as much as possible while the integrity of the film is not damaged (no holes and no fracture appear), so that the film is microporous. The stretching is beneficial to the dispersion of the far infrared nano ceramic powder on one hand, and the far infrared nano ceramic powder fully reveals the interface on the other hand.
Further, the textile in the step (2) is any one of a polyester fabric, a spandex fabric and a chinlon fabric; the preheating temperature is 100-120 ℃, so that the microporous membrane can be attached to the preheating furnace conveniently.
Further, the hot roller pressing in the step (3) is carried out by using 3-5 groups of hot rollers for pressing, the temperature of the hot rollers is 80-120 ℃, and the working linear speed is 6-12 m/min.
Further, in the step (3), the grinding is performed by a grinding machine, the grinding machine is a roller, the surface of the grinding machine is 200-mesh sand, and the microporous membrane is subjected to grinding treatment, so that the far infrared nano ceramic powder is fully dispersed and an interface is exposed.
The invention also provides the heating health-care composite textile prepared by the method. Aiming at the problems that the far infrared heating effect is influenced by poor dispersion uniformity of the existing far infrared nano ceramic powder used as a heating material in a textile finishing agent and the defect that the far infrared nano ceramic powder is difficult to firmly adhere to textiles, the invention obtains the product by firstly dispersing and compounding the far infrared nano ceramic powder with graphene and then compounding with nylon, then performing melt extrusion and biaxial stretching with the maximum multiplying power, attaching the obtained product to a textile object, and then performing multi-group rolling and sanding.
