Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
As shown in fig. 1-4, a waterproof moisture-permeable intelligent fabric comprises a base fabric 1, wherein the base fabric 1 is formed by interweaving warp yarns and weft yarns; the warp yarn and the weft yarn are composite yarn 11 formed by spirally twisting regenerated cellulose fiber single yarn and water-soluble fiber, and spiral grooves 12 are formed in the composite yarn 11; the base fabric 1 is characterized in that breathable fabric layers 2 are arranged on two sides of the base fabric 1, the breathable fabric layers 2 are formed by mutually weaving warps 21 and wefts 22, and the wefts 22 are formed by circularly and alternately arranging two moisture-absorbing and sweat-releasing fibers 5 and one ramie fiber 6; a waterproof layer 4 is bonded on the breathable fabric layer 2 through a polyurethane adhesive 3; the polyurethane adhesive 3 is attached with a layer of phase-change temperature-regulating microcapsule powder 7.
Specifically, the regenerated cellulose fiber single yarn and the water-soluble fiber single yarn or filament are compounded, and the single yarn, the single yarn and the filament are mutually wrapped through the siro spinning and the sirofil spinning process to form the double-strand composite yarn 11. The water-soluble fiber is arranged in the siro spinning or sirofil yarn, and after the fiber removing treatment, the new yarn can present a special-shaped structure, the surface presents a spiral clear and uniformly distributed groove 12, which is beneficial to the exchange and circulation of air on the groove 12 and improves the moisture-conducting speed and the air-permeable effect of the fabric.
Further, a layer of phase change temperature regulating microcapsule powder 7 attached to the polyurethane adhesive 3 is liquid-solid phase change type temperature regulating microcapsule powder prepared by a coating technology, and after microcapsule coating, the phase change core material can be prevented from being exposed in an external environment and being free from the influence of the external environment, and the high efficiency of energy storage and release of the phase change material is maintained. The material in the phase change interval of 23-33 deg.c is selected to maintain constant skin temperature. The single phase-change point temperature regulating material or the mixed phase-change point temperature regulating material is used, and the purpose is to flexibly control the phase-change temperature control range. Polyurethane is used as a carrier, phase-change temperature-regulating microcapsule powder is coated on the fabric, and when the temperature of the external environment where the fabric is located rises, the phase-change material is changed from a solid state to a liquid state to absorb heat, so that the body surface temperature is reduced. On the contrary, when the temperature of the external environment is reduced, the phase-change material is changed from a liquid state to a solid state to release heat, thereby reducing the heat released by the human body to the surroundings, keeping the normal body temperature of the human body, providing a comfortable microclimate environment in the clothes for the human body, and enabling the human body to be always in a comfortable state. And the polyurethane has good elasticity and fine hand feeling. Not only can provide fine surface hand feeling, but also can effectively relieve mechanical stress generated by shrinkage or expansion when the phase of the phase-change temperature-adjusting microcapsule powder is changed through excellent elasticity, and plays a role in assisting in protecting the phase-change temperature-adjusting microcapsule powder. Preferably, the thickness of the polyurethane adhesive 3 is 0.1 to 0.15 mm.
Further, the thickness of the breathable fabric layer 2 is 0.3-0.5 mm. Still further, the warp 21 of the breathable fabric layer 2 is formed by stranding and twisting tencel fibers and viscose fibers, and the combination of the tencel fibers and the viscose fibers enables the breathable fabric layer to have good breathability.
Furthermore, the waterproof layer 4 is a PU microporous film. The PU microporous film has the advantages of good uniformity, high filtration efficiency, stable air permeability, low temperature resistance, small friction coefficient, high filtration speed, long service life and the like, and the PU microporous film has smooth film surface, low surface tension, good non-adhesiveness and hydrophobicity and obvious ash removal effect. The PU microporous film can be combined with the breathable fabric layer 2, and when the body temperature rises due to the violent movement of a user, the PU microporous film can discharge water vapor and body heat through the breathable fabric layer 2 and the waterproof layer 4 by virtue of Brownian motion. The PU microporous film has high air permeability and heat preservation degree and soft hand feeling, so that the PU microporous film can be widely applied to outdoor sports clothes.
Example two
Unlike the above-described embodiments, theThe waterproof layer 4 of (2) is an intelligent waterproof moisture permeable TPU film. Furthermore, the intelligent waterproof moisture permeable TPU film has the moisture permeability of more than 5000g/m224hrs, hydrostatic pressure resistance value greater than 10000mmH2O, so that the waterproof and moisture-permeable performance is good. The moisture permeability of the waterproof moisture-permeable intelligent fabric designed in the way can be changed along with the change of environmental factors, can spontaneously adapt to the perspiration amount of a human body in different environments, has intelligent self-adaptability, is green and environment-friendly, has good waterproof moisture permeability, is windproof, cold-resistant and can be washed normally, and is suitable for outdoor sports wearing environments and activity modes.
The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
