Description

Porous yarn with temperature adjusting function and preparation method thereof
Technical Field
The invention belongs to the technical field of heat management materials, and relates to porous yarn with a temperature adjusting function and a preparation method thereof.
Background
In the twenty-first century, human society has entered a rapid economic development period. In many countries, natural resources are being over-utilized for rapid development of economy, and excessive consumption of energy directly causes large emission of greenhouse gases, seriously affects climate balance and causes greenhouse effect. Human being is a kind of constant temperature animal, and when the core body temperature of the human being can not maintain normal, the human health will be destroyed, even threatened to life. In the times of day with ever changing climate, the thermal comfort of human body plays a crucial role in the development of social economy, so a great deal of energy is consumed every year all over the world to meet the thermal comfort degree required by human body. Therefore, research and development of some advanced energy saving technologies to meet the requirement of thermal comfort of human body has been the focus of attention. In recent years, the concept of personal thermal management to improve the local microclimate around the human body has been considered as a promising approach to energy conservation. Currently, there are advanced techniques to improve the thermal comfort of the human body by controlling the heat transfer of textiles between the human body and the environment.
The traditional heat management material can adjust the microclimate between the human body and the environment to a certain degree, and meets the requirement of thermal comfort of the human body. However, the existing temperature-regulating and heat-managing materials mainly comprise phase-change materials, have the defects of single temperature-regulating means, poor mechanical strength, poor environment-adaptive capacity, poor comfort, poor safety and the like, and limit the application range of the materials. The yarn is made into a high-strength textile material, has the characteristics of controllable process, wide application range, high strength, low cost and the like, and is widely applied to the textile field. Therefore, the temperature-adjusting and heat-managing yarn with good temperature-adjusting effect, wide applicable environment, convenient use, simple process and high safety is prepared by the method for adjusting and controlling the structure and the radiation transfer direction, and has important practical significance for improving the actual service performance of yarn materials and expanding the application range of the yarn materials in the field of improving the thermal comfort of human bodies.
Currently, there have been some studies in the art by those skilled in the relevant art. Patent CN202110768208.8 discloses a heat-preservation and heat-dissipation bifunctional heat management fabric and a preparation method thereof, the technology is characterized in that metal nanoparticle layers and porous polymer coatings are respectively deposited on two sides of a fiber fabric, the inhibition of heat radiation and the efficient absorption of sunlight are realized by utilizing local surface plasmon resonance, the efficient scattering of the sunlight is realized by utilizing internal air holes, the switching of a heat preservation cooling mode is realized in a forward and reverse turning mode, the temperature regulation is realized, the fabric obtained by the technology only depends on the change of the heat radiation, the heat convection is difficult to regulate and control, and the fabric is difficult to adapt to the temperature change in a higher range. Patent CN201110058428.8 discloses a phase-change temperature-regulating woven fabric and a preparation method thereof, and a preparation method of polyurethane aerogel fibers, the method takes a common woven fabric as a matrix, combines a phase-change material with the fabric in a phase-change microcapsule impregnation liquid manner to obtain the woven fabric with certain temperature regulating capability, the material prepared by the method has a temperature regulating effect only when the phase-change material absorbs or releases heat, the temperature regulating effect is lasting for a short time, and the defect that the phase-change microcapsules are easy to drop exists, so that the practical application of the material is limited. Patent CN202010461490.0 discloses a temperature-self-regulating moisture-permeable waterproof textile and a preparation method thereof, in the method, a composite solution of polyvinyl alcohol and polytetrafluoroethylene emulsion is adhered on the surface of an adhesive fiber adsorbing polyethylene glycol and is cured to obtain an adhesive fiber carrying a phase-change material, then the adhesive fiber carrying the phase-change material and spandex are twisted and woven, and finally after finishing processing, a textile having both a waterproof moisture-permeable function and a certain temperature-regulating capability is obtained.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and the like and provide the porous yarn with the temperature adjusting function and the preparation method thereof.
The purpose of the invention can be realized by the following technical scheme:
a porous yarn with a temperature adjusting function and a preparation method thereof are disclosed, the preparation method comprises the following steps:
the first step is as follows: lightly twisting the untwisted slivers through a two-for-one twister to obtain low-twist slivers with loose fiber arrangement and stable structures;
the second step is that: putting the low-twist sliver into a foaming solution for high-pressure impregnation, so that the foaming solution is completely immersed into the low-twist sliver and uniformly dispersed among fibers, taking out the low-twist sliver and putting the low-twist sliver into a mold with a proper size for foaming treatment, so that the foaming solution in the low-twist sliver generates bubbles and generates a squeezing action on the fibers around the bubbles, and then drying the low-twist sliver so that a solute forms a porous structure in the low-twist sliver to obtain a porous foaming sliver;
the third step: putting the porous foaming sliver into a two-for-one twister, and moderately twisting to fully fix the inter-fiber pores inside the porous foaming sliver to obtain porous foaming yarn;
the fourth step: putting the porous foaming yarns into a foaming dissolving solvent for soaking and dissolving, wherein the foaming dissolving solvent has solubility on the foaming material, and taking out the porous foaming yarns after drying to obtain the porous yarns;
the fifth step: putting the porous yarns into a Shape Memory Polymer (SMP) solution and carrying out ultrasonic dipping treatment to ensure that the SMP solution is fully filled in the internal pores of the porous yarns to replace the original position of a foaming material, thus obtaining the SMP filled porous yarns;
and a sixth step: and (2) soaking the SMP filled porous yarns in a phase separation solution to ensure that the phase separation solution is uniformly coated on the surface of the SMP filled porous yarns and in the pores among the fibers, and then performing rapid phase separation treatment, drying process and crosslinking stabilization treatment to form a dense porous membrane on the surface of the SMP filled porous yarns and in the pores among the fibers, so as to stabilize the SMP filled porous yarns and the porous structure thereof, and finally obtaining the high SMP filled porous yarns with the temperature regulation function.
