example 1

The light and thin warm-keeping fabric with the air cushion film-like structure has the following weaving process parameters and raw material settings as shown in the following table 1.

Table 1 weave architecture design and weaving process parameter set for example 1

The fabric provided in said example 1, wherein the first structural region of the fabric is a double layer weave, both the face and back weaves being plain weaves; the warp-wise connection area and the weft-wise connection area of the second structure area are both single-layer tissues and are composed of square and flat tissues. The fabric associates the double-layer structure of the first structure area from the warp direction and the weft direction through the warp-direction linking area and the weft-direction linking area respectively, so that the second structure area forms a flat and stable single-layer linking channel in the warp direction and the weft direction. In the double-layer structure of the first structure area, the filling weft is lined between the two layers of fabrics; after air washing and filling, due to the fiber removal of the water-soluble vinylon filaments, the PI staple fibers in the filling yarns are filled with loose fibers in the double-layer structure and are distributed in a fluffy manner, so that double-layer tissue areas are foamed, and a local convex three-dimensional rectangular array arrangement structure of the air cushion-like film is presented. In addition, the water-soluble vinylon filaments have a certain shrinkage effect in water, so that the first structure area and the second structure area of the fabric shrink to a certain degree while removing dimension, the thickness feeling of the fabric is increased, the convexity of the air cushion-like film structure is further promoted, and the warm-keeping and heat-insulating effects of the fabric are effectively improved.

Wherein the polyimide material (PI) has a thermal conductivity of 0.031W/(m.k), and the wool has a thermal conductivity of 0.029W/(m.k); that is, PI has excellent heat insulating effect similar to wool. In the embodiment 1, PI and cotton are used as main raw materials, and through the configuration of yarns, the main raw material of a fabric layer formed on the surface contacting with the outside is cotton, so that the fabric has good hand feeling; the fabric layer facing the human body contact is PI, so that the heat transfer between the human body and the environment can be effectively reduced, and a good warm-keeping and heat-insulating effect is provided. Experiments show that the light and thin warm-keeping fabric which can be washed by water and has good handfeel and thermal resistance of 0.158m can be prepared by the preparation method of the example 1²·℃·W^-1。

It should be noted that, in this embodiment, the weave structures of the warp-wise coupling region and the weft-wise coupling region are the same, but those skilled in the art should understand that the weave structures of the warp-wise coupling region and the weft-wise coupling region may also be different according to the requirements of the design and application of the product. It should be noted that, it should be understood that fig. 1 is only for convenience of distinguishing the warp-wise coupling regions from the weft-wise coupling regions, and thus different filling patterns are used and do not indicate that the warp-wise coupling regions and the weft-wise coupling regions are different in structure.

Comparative example 1

Comparative example 1 differs from example 1 in that: the water-soluble vinylon filaments in the weft insertion yarns are replaced by the water-insoluble vinylon filaments. Because the water-insoluble vinylon filaments are wrapped outside the pad weft yarns, the pad weft yarns are continuously padded into the two layers of the first structural area in the mode that the water-insoluble vinylon filaments are wrapped with the PI staple fiber roving in the air washing and filling processAnd the fabrics are interwoven in a second structural area in a mode that the PI short fiber roving is wrapped by the water-insoluble vinylon filaments. As can be seen from the test, the comparative sample prepared has a thermal resistance of 0.078m²·℃·W^-1Significantly lower than that of example 1 (0.158 m)²·℃·W^-1)。

It can be seen that, in example 1, the staple fiber roving is wrapped by the water-soluble vinylon filament, and when the fabric is subjected to air washing, the staple fiber roving is disintegrated and is fluffy and distributed between two layers of fabrics in a fiber form based on the water solubility of the water-soluble vinylon filament and the dissolution of the vinylon filament, and the heat retention property of the fabric can be effectively improved by matching with the local convex three-dimensional rectangular array arrangement structure of the air cushion-like film of the fabric, so that the light, thin, comfortable and warm-keeping fabric can be prepared. And the fabric has a flat structure and is convenient to weave.

In the embodiment, the mudar horn fiber has a unique morphological structure, has high hollowness, good heat retention, good hygroscopicity and excellent antibacterial efficiency, but has the defects of low strength, no turning, easy brittle fracture, poor cohesion and the like which are not beneficial to spinning, and limits the application range of the mudar horn fiber. The water-soluble vinylon fiber is a functional differential fiber, has better spinnability and ideal water solubility, is nontoxic, tasteless and transparent after being dissolved in water, and can be naturally biodegraded. Consequently the utility model discloses a pre-oxidized fiber, calotropis gigantean fibre and package twine the second package of twining the yarn and constitute at calotropis gigantean fibre and the water-soluble vinylon of pre-oxidized fiber periphery and for filling up the woof, overcome the defect that calotropis gigantean fibre spinnability is low for fill up the woof when possessing excellent antibiotic, sweat-absorbing performance, still possess excellent mechanical properties and spinnable performance.

Wherein, the water-soluble vinylon fiber is used as companion textile, and the finished woven fabric is subjected to fiber removal and post-finishing. In the process of removing the fiber, the water-soluble vinylon fiber in the yarn is dissolved and removed, only the pre-oxidized fiber and the mudar fiber are left, the filling yarn is changed into a loose fiber from a yarn shape, and then the yarn is dried and finished, so that the yarn structure is fluffy, the fabric presents fluffy, soft and comfortable feeling, the fluffy degree of an air cushion film-like structure of the fabric is improved, the protruding structure of the fabric is further promoted to be remarkable, the softness of the fabric is high, and the function of washing and filling is realized.

And the continuous conduction of the weft direction of the fabric is realized through the conductive metal wires in the weft padding yarns. As shown in fig. 7, the light emitting diode can illuminate and emit light (as shown in fig. 7 a, 7B, and 7C) when the fabric is connected with the light emitting diode in an experimental test, which proves that the fabric has continuous conductive channels in the weft direction and excellent antistatic performance; and the conductive metal wire pad in the fabric is arranged between the double-layer fabrics, does not participate in interweaving and is not in direct contact friction with the outside, so that the conductive metal wire pad is protected, and the service life of the conductive metal wire is prolonged.

Table 6 weave architecture design and weaving process parameter set for example 6

Example 6 is analyzed with reference to FIGS. 11-16 and Table 6:

fig. 11 is a top view of a fabric according to embodiment 6 of the present invention. In the present embodiment, basalt fiber and Fe are introduced as shown in fig. 12 to 13₃O₄Functional cushion weft yarns formed by functional staple fiber roving and water-soluble vinylon filaments mixed by kapok yarns are subjected to air washing and fiber removal treatment, and the prepared fabric can fully exert the infrared stealth function of the material and simultaneously has water-washing resistance. And further dyeing the designed fabric by introducing a reducing dye to absorb near-infrared light waves, so that the fabric has good wear and infrared stealth performance. Therefore, the infrared invisible mask can be widely applied to military occasions and can realize the function of thermal infrared invisible under different conditions.

The reducing dye is insoluble in water, can be reduced and dissolved into leuco sodium salt in alkaline strong reducing liquid during dyeing to dye the fiber, and can be recovered into insoluble dye lake after oxidation to be fixed on the fiber, so that the fastness to washing and sun is high. The purpose of introducing the reducing dye is to meet the requirement of compatible visible light stealth. The basalt continuous fiber has excellent wave-absorbing performance and wave-transmitting performance besides excellent performances of high strength, electrical insulation, corrosion resistance, high temperature resistance and the like.

The kapok fiber has a unique structure with large and hollow cell walls, namely, the wall is thin, the longitudinal surface is provided with micro convex marks, the cross section is of a hollow structure with a circular or oval shape, and the kapok fiber has the characteristics of large heat capacity and low conductivity, so that the kapok fiber has a good heat insulation effect. After the kapok fiber fabric is used for coating the object, the infrared radiation emitted by the object outwards can be reduced, the heat conduction outwards is reduced, the infrared radiation intensity of the object is reduced, the infrared characteristics of the target and the background are similar, and the infrared low detectable rate is realized. The utility model uses Fe₃O₄Kapok blended yarns, incorporating functional Fe₃O₄The excellent adsorption performance of the particles and the heat insulation and infrared radiation reduction performance of the kapok fibers improve the infrared stealth function of the functional cushion weft to a great extent.

As shown in fig. 12, the fabric produced in example 6 had the first structure region constituted by the surface texture and the inner texture, and the second structure region constituted by the surface texture and the inner texture through binding by binding, and exhibited a locally convex three-dimensional rectangular array arrangement structure of the air-cushion-like film by binding of the two structure regions. On one hand, the infrared stealth functional pad weft yarns positioned on the double-layer fabric part of the first structural area are untwisted through subsequent air washing, and are evenly and fluffily distributed in the surface layer fabric and the inner layer fabric, so that the service life of the stealth functional fiber material is effectively prolonged. On the other hand, the unique hollow structure of the kapok fiber effectively contains functional material particles Fe₃O₄And form protection. Based on the two points, the wearing comfort of the invisible fabric is guaranteed, and meanwhile the water washing resistance and the wear resistance of the infrared invisible fabric are achieved. When the double-layer structure is taken, the double-layer bulge part formed by the first structure area is in point contact with the human body, and the double-layer binding structure of the second structure area can form an airflow conduction channel so as to be beneficial to the guiding out of moisture.

Fig. 13 is a graph showing the simulated effect of the fabric provided in example 6 applied to military equipment and military clothing. As shown in fig. 14, the water temperature of the beaker in fig. 14B was 71.5 ℃ at room temperature (as shown in the infrared camera photograph a in fig. 14). Fig. 15 shows that when the beaker is covered with the fabric having the stealth function woven in this example (shown as B in fig. 15), infrared photography is performed, it is found that infrared light emitted from hot water is greatly reduced, and the temperature of the calibration center is only 28.1 ℃ (shown as a in fig. 15). As can be seen from fig. 16, when the fabric with the stealth function woven in this embodiment is subjected to an infrared spectrum test, the infrared spectrum is substantially absorbed, which further proves the excellent infrared stealth function of the fabric.
