Description
Technical Field
The invention belongs to the technical field of intelligent thermal fibers, and particularly relates to a preparation method of a friction heating thermal fabric.
Background
At present, functional fibers for personal warm keeping are mainly classified into two types: one type is the traditional passive warm-keeping fiber materials such as cotton and hemp, and the clothes made of the materials are too bulky to meet the warm-keeping requirement of the extremely low temperature environment; the other type is active heat-preservation fiber, and the heat-preservation effect is achieved by means of self-heating of the fiber, so that a human body is in a heat balance state.
Active type warm-keeping fabrics in the prior research are mainly divided into five types according to different mechanisms, wherein when moisture is absorbed by the moisture-absorbing and heating fibers, hydrophilic groups in fiber molecules are combined with water molecules, and kinetic energy of the water molecules is reduced and converted into heat energy to be released, so that the warm-keeping effect of the moisture-absorbing and heating fibers depends on the number of the hydrophilic groups in the molecular structure; the chemical heating fiber generates heat through chemical reaction, and the chemical heating fiber is invalid once and cannot be reused; the phase-change fiber is influenced by the phase-change temperature, and the heat supply time to the human body is limited; the light energy heating and the electric energy heating require additional energy input and are limited by external use conditions.
The essence of frictional heating is the process of collision of molecules on the surfaces of objects that rub against each other. In the process of mutual friction of objects, collision among molecules is random and frequent, so that the internal energy of the surface of the object is increased, and macroscopically, the temperature is increased. However, the relative friction among the fibers of the existing clothes is small, the conversion rate from mechanical energy to internal energy is low, the temperature change can be almost ignored, and the effect of keeping warm through friction is poor.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a preparation method of a friction heating warm-keeping fabric, which comprises the following steps:
s1, performing surface roughening treatment on at least one of the plurality of molded fibers with different Young' S moduli to increase the friction coefficient between the molded fiber subjected to the surface roughening treatment and other molded fibers;
and S2, compounding the molded fibers and then weaving to obtain the friction heating thermal fabric.
In some embodiments, at least two of the plurality of shaped fibers have a difference in young's modulus of at least one order of magnitude. Within the elastic limits of an object, the stress is proportional to the strain, the ratio is called the young's modulus of the material, and it is a physical quantity that characterizes the properties of the material, and is related only to the chemical composition of the material itself, to its structural changes, and to the heat treatment state. The magnitude of the Young's modulus indicates the rigidity of the material, and the larger the Young's modulus, the less likely it will deform. For example, the Young modulus of the polyester fiber selected by the invention can reach 4000MPa, the polyester fiber has excellent wear resistance, the modulus of the polyurethane PU fiber is only about 40MPa, and the deformation of PU is far higher than that of the polyester fiber under the action of the same external force, so that the integral relative motion is realized.
In some embodiments, the shaped fibers may be polyester fibers (commonly known as "dacron"), polyurethane fibers (PU), polyamide fibers (commonly known as "nylon"), polypropylene fibers (commonly known as "polypropylene"), polyethylene fibers, and the like, but are not limited to these listed types.
In some embodiments, the shaped fiber may be a composite material, preferably a composite fiber formed by compounding at least two materials of polyester, polyurethane, polyamide, polypropylene and polyethylene.
In some embodiments, the processing of the shaped fiber comprises hot drawing, electrospinning, or extrusion.
Specifically, in the hot drawing, under the action of external tension, the fiber is forced to pass through a die hole to generate plastic deformation so as to obtain the formed fiber with the same shape and size as the die hole, and the drawing heating temperature can be adjusted according to different fiber materials and wire diameters. The extrusion forming process is similar to hot drawing in principle, and fiber material is set inside mold cavity and extruded out of the mold cavity under powerful pressure and certain speed to obtain fiber in required shape, size and certain mechanical performance. Electrospinning is a fiber manufacturing process in which a polymer solution is sprayed in a strong electric field, and under the action of the electric field, liquid drops at the needle of an injector change from a spherical shape to a conical shape (i.e., a "taylor cone") and extend from the tip of the cone to obtain fiber filaments, thereby producing polymer filament fibers with nanometer-scale diameters.
In some embodiments, the electrospinning is coaxial electrospinning, and the formed fiber processed by the coaxial electrospinning process has a structure with a porous surface and a hollow interior.
The traditional spinning equipment used for electrostatic spinning is a single capillary nozzle and is usually used for preparing solid nano fibers with smooth surfaces and single components, but the method can only obtain the nano fibers with single materials, cannot obtain composite materials with multifunctional structures, and has the problems of lack of surface specificity, poor mechanical properties and the like. Coaxial electrospinning is a new method developed on the basis of the traditional electrospinning technology, and continuous core-shell and hollow structure nanofibers can be prepared in one step. During coaxial electrostatic spinning, adorn nuclear layer spinning solution and shell layer spinning solution respectively in different syringes, the system of spouting is become by two coaxial but not the capillary of different internal diameters, and under the high-voltage electric field effect, shell layer spinning solution flows out the back and joins with nuclear layer spinning solution, because two kinds of solutions join the time shorter in capillary mouth department, and the diffusion coefficient of two kinds of solutions is lower, therefore two kinds of spinning solutions can not mix before the solidification. The shell layer spinning solution is stretched in high frequency, strong shearing stress is generated at the interface of the inner layer solution and the outer layer solution when the shell layer spinning solution is sprayed at high speed, the core layer spinning solution moves coaxially along the shell layer under the action of the shearing stress, bends, swings, deforms and solidifies to form the superfine coaxial composite nanofiber. If the core layer material in the composite nanofiber is removed by heating or dissolving, and the shell layer material is left, the hollow nanofiber with porous surface is obtained. Compared with the conventional smooth-surface fiber, the nanofiber with the structure has larger specific surface area and roughness, and the friction force between the fibers is increased.
In some embodiments, the method of surface roughening treatment includes surface etching, coating, dip coating, or heat treatment.
In particular, zinc oxide or silicon dioxide may be etched on the surface of the shaped fiber. For example, when polyethylene fibers are prepared by extrusion molding, polyethylene and zinc oxide or silicon dioxide powder are primarily mixed, and are further uniformly mixed in the process of melting, plasticizing and extruding plastic particles, so that composite polyethylene fibers doped with zinc oxide or silicon dioxide particles can be obtained, and composite fibers with different diameters can be obtained by adjusting the size of a die. In order to obtain polyethylene fibers with rough surfaces, composite fibers obtained by extrusion are ultrasonically soaked by dilute hydrochloric acid solution or sodium hydroxide solution, then doped zinc oxide or silicon dioxide particles are removed by etching, and then the polyethylene fibers with porous surfaces are obtained by repeatedly cleaning the composite fibers with deionized water and drying the composite fibers. In this process, the surface morphology of the fiber is not only related to the process parameters in the extrusion molding process, such as temperature, plasticizing time, extrusion speed, etc., but also more important to control the morphology of the final fiber surface by controlling the particle size and content of the doped filler.
In addition, the surface of the formed fiber may be coated with a material having good friction properties, such as but not limited to polytetrafluoroethylene, polydimethylsiloxane, zinc oxide nanowire array, and the like. Preferably, the formed fiber is pre-stretched to a certain extent during coating, and the pre-strain is released after the coating is cured, so that a wrinkle microstructure is formed on the surface of the fiber, and the roughness of the surface of the fiber is increased. Similarly, the shaped fiber can also be dipped in a material solution, the modified material is uniformly adsorbed to the surface by the capillary action of the fiber surface, and then taken out and dried. The modified material can be carbon nano tube, polyvinylidene fluoride, polyaniline and the like which are subjected to functional modification. Alternatively, the shaped fiber may be a composite material in which one or some of the components are volatilized by heat treatment to obtain a shaped fiber having a porous structure.
In some embodiments, the surface morphology and structure of the shaped fiber after the surface roughening treatment can be a porous structure, a sawtooth structure, a strip structure, and other various surface structures.
Specifically, the porous structure is a common surface roughness structure, and can be formed by the above process method, which is not repeated herein. The sawtooth structure can be formed by an improved spin coating process, and the specific process comprises the following steps of forming a glass mould with inclined array multiple holes by laser, pouring a small amount of prepared polymer solution, and forming a thin film with a polymer thin layer on the upper surface and an inclined strip-shaped sawtooth structure on the lower surface by using a spin coating machine; removing the mold after the polymer solution is solidified and molded to obtain a serrated film; and finally, correspondingly matching the obtained serrated film, and enabling the serrated structures to move mutually to generate friction when the film is stretched. It should be noted that in the process, the density and the inclination angle of the porous array in the mold are adjusted to optimize the effect of the relative movement, and further optimize the friction effect. The elongated structures can be formed by extrusion of microfiber composites, which is an interesting class of polymer composites, where different polymer materials undergo different morphological changes during melt blending of the polymers, such as breaking and coalescence of polymer droplets, and are stretched during melting, plasticization, extrusion to cause fibrillation, which is a complex process influenced by conditions such as extrusion temperature, screw rotation speed, cooling time, stretching ratio, and mixing ratio of the polymers.
In some embodiments, the structure of each formed fiber after being combined includes, but is not limited to, a coaxial structure, a sandwich structure, a spiral twisted structure, or a corrugated structure.
