The warm-keeping effect is strong, the health of students is protected, meanwhile, the intelligent degree is high, and the comfort of school uniforms is improved. However, the school uniform has a too complicated structure, high production cost and inconvenient cleaning after use.
Disclosure of Invention
Therefore, aiming at the above contents, the invention provides a thermal comfortable school uniform, which solves the problem of poor thermal insulation of the school uniform in the prior art.
In order to achieve the purpose, the invention is realized by the following technical scheme:
the thermal and comfortable school uniform comprises a school uniform body, wherein the school uniform body fabric comprises an inner layer, a middle layer and an outer layer, the middle layer is arranged between the outer layer and the inner layer, the inner layer is formed by interweaving warp and weft yarns, the warp yarns are formed by blending modified polyester fibers, viscose fibers and conductive fibers, the weft yarns are formed by blending modified polyester fibers, bamboo fibers and conductive fibers, the middle layer is a moisture absorption and heating fiber fabric layer, the outer layer is a PTFE waterproof moisture permeable fabric layer, and the surface of the outer layer is provided with an ultraviolet resistant coating.
The further improvement is that: the preparation method of the modified polyester fiber comprises the following steps: crushing far infrared ceramic powder to a particle size of 10-50 microns, adding a silane coupling agent, polyvinylpyrrolidone and ethylene bis-stearamide, uniformly stirring and mixing, blending with polyester chips, and performing melt extrusion to obtain modified polyester master batches; mixing the modified polyester master batch and the polyester chips according to the mass ratio of 1: and 20-40, performing melt spinning to prepare the modified polyester fiber.
The further improvement is that: the modified polyester master batch comprises, by weight, 3-6 parts of far infrared ceramics, 0.3-0.8 part of a silane coupling agent, 0.8-2 parts of polyvinylpyrrolidone, 0.4-1.6 parts of ethylene bis stearamide and 80-90 parts of polyester chips.
The further improvement is that: the modified polyester fiber accounts for 45-55% of the warp, the viscose fiber accounts for 35-45% of the warp, and the conductive fiber accounts for 5-15%.
The further improvement is that: the weft yarns comprise 36-48% of modified polyester fibers, 44-56% of bamboo fibers and 2-13% of conductive fibers.
The further improvement is that: the warp density of the inner layer is 500-550 pieces/10 cm, and the weft density is 420-480 pieces/10 cm.
By adopting the technical scheme, the invention has the beneficial effects that:
the polyester fiber fabric has the advantages of high modulus, high strength, high elasticity, good shape retention and heat resistance, but the polyester fiber fabric has hard hand feeling, poor dyeing property, poor air permeability and poor moisture absorption. The viscose fiber is soft and has good skin-friendly property, but the shape retention of the viscose fiber fabric is poor. The bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance, good dyeing property and the like, and in addition, the bamboo fiber also has the functions of natural antibiosis, bacteriostasis, mite removal, deodorization and ultraviolet resistance, but the bamboo fiber fabric has low strength and cannot bear high-strength pulling. The invention respectively blends the polyester fiber with the viscose fiber and the bamboo fiber, so that the performances of different fibers are complementary, and the fabric formed by blending the warp yarn and the weft yarn has the advantages of the polyester fiber and the viscose fiber and the bamboo fiber. The polyester fiber has poor moisture absorption capacity, and static electricity is easy to generate and accumulate in autumn and winter of air drying, so that the antistatic polyester fiber fabric has an antistatic effect by adding the conductive fiber into the warp and weft.
On the basis of the advantages of common polyester fibers, the modified polyester fibers are prepared by using polyester chips and far infrared ceramic powder as main raw materials, the modified polyester fibers are woven into the inner layer by using the modified polyester fibers as the raw materials, the far infrared ceramic powder can absorb visible light and reflect the far infrared light in the using process, after the visible light is absorbed, the far infrared light is transmitted to water molecules in a human body to perform resonance reaction under the action of the far infrared light, protein and other macromolecules in the human body are accelerated to be activated due to the resonance of the water molecules, the heat energy of the human body is transferred to the surface layer of the human body, and the human body feels warm from inside to outside. In addition, blood cells in the human body can be irradiated by far infrared light to generate resonance, so that the blood circulation speed is increased, the human body feels warm, and the heat loss of the human body is prevented.
The middle layer of the invention takes the moisture absorption heating fiber as the raw material, after absorbing the water vapor emitted by human body, the fiber molecules and the water molecules are mutually attracted and combined, the kinetic energy of the water molecules is reduced and converted into heat to be released, and the temperature is increased to achieve the effect of keeping warm.
The special hollow structure of the bamboo fiber can contain a large amount of static air in the cavity, so that heat is prevented from being transmitted and dissipated outwards, and the heat retention of the clothes is improved. Most of traditional warm-keeping clothes adopt a passive warm-keeping mode for preventing or reducing outward loss of human body heat, such as hollow fiber fabric, fluffy down feather, duck down feather and the like, and the clothes are thick, heavy and bulky. The bamboo fiber heat-insulation fabric not only prevents heat loss by utilizing the hollow structure of the bamboo fiber, but also actively keeps warm by the following two aspects: the polyester fiber is modified, so that the garment has a far infrared function, and the far infrared light enables the interior of a human body to generate a chain reaction, stimulates the rise of the temperature of the surface layer of the skin and achieves the effect of positive heat preservation; and (II) absorbing and storing external heat and transmitting the external heat to a human body by utilizing the characteristics of the moisture-absorbing heating fibers.
The warp and weft yarns are optimized in proportion of various fibers, the modified polyester fibers account for 45-55%, the viscose fibers account for 35-45%, the conductive fibers account for 5-15%, the modified polyester fibers account for 36-48%, the bamboo fibers account for 44-56% and the conductive fibers account for 2-13% in the warp yarns, and therefore the fabric is balanced in warmth retention, breathability, comfort and wrinkle resistance. The heat preservation performance and the air permeability performance of the fabric are directly influenced by the warp and weft density, when the warp and weft density is too large, the heat preservation performance of the fabric can be effectively improved, but the air permeability is poor; when the thread count is too small, the opposite is true. Through a large number of research experiments, the warmth retention and air permeability of the inner layer fabric can reach excellent levels when the warp density is 500-550 pieces/10 cm and the weft density is 420-480 pieces/10 cm.
