A method for producing a fabric of an air cushion film-like structure provided by the present invention is described below with reference to examples 1 to 7 and comparative examples 1 to 3:

example 1

A preparation method of a light and thin warm-keeping fabric with an air cushion film-like structure comprises the following steps:

s1, determining that the surface weave and the inner weave of the first structure area both adopt plain weave, and the second structure area is squareness weave; determining the ratio of the number of warp yarns in the first structure area to the number of warp yarns in the weft-wise binding area in the second structure area to be 4: 1; determining the materials of the warp yarns, the weft yarns and the cushion weft yarns of the first structural area and the second structural area (shown in the table 1);

And S3, after weaving, performing air washing on the fabric, untwisting and uniformly dispersing the filling yarns in the first structure area, and filling the filling yarns in the first structure area to make the first structure area convex, so as to obtain the fabric with the air cushion film-like structure.

The weaving process parameters and raw material settings during weaving are shown in table 1 below.

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

The fabric prepared in example 1, wherein the first structural region of the fabric was a double layer weave, both the surface and the inner weave were 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, and other steps are basically the same as those in the embodiment 1 and are not described again. Since the water-insoluble vinylon filaments are wrapped around the pad weft, the pad weft is continuously padded between the two fabrics in the first structural area in the form of the water-insoluble vinylon filaments wrapped around the PI staple rovings and is interwoven in the second structural area in the form of the water-insoluble vinylon filaments wrapped around the PI staple rovings in the air wash-and-fill process of step S3. 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.

Example 2

The present embodiment provides a method for preparing a washable automobile interior fabric with an air cushion film-like structure, which is different from that in embodiment 1 in terms of fabric textures, raw materials and weaving process parameters in a first structure region and a second structure region, and as shown in table 2 in detail, other steps are substantially the same, and are not repeated herein.

Table 2 weave architecture design and weaving process parameter set for example 2

Example 2 is analyzed with reference to fig. 3-5 and table 2:

fig. 3 is a top view of a fabric according to example 2 of the present invention. As shown in fig. 4, in the fabric prepared in example 2, the first structure region is composed of the surface structure and the inner structure of the twill weave structure, and the second structure region is a single-layer structure of the twill weave structure.

The main yarn raw material of the embodiment 2 adopts flame-retardant polyester, and functional cushion weft yarns composed of mudar roving, pre-oxidized silk and water-soluble vinylon filaments wrapped on the surface of the mudar roving are introduced into the double-layer fabric. Through subsequent air washing, the pre-oxidized fibers with the adsorption and flame-retardant functions and the calotropis gigantea fibers with the antibacterial and sweat-absorbing performances are uniformly distributed and fluffy between the surface layer and the inner layer of the first structure area of the fabric, and a local convex three-dimensional rectangular array arrangement structure of the air cushion-like film is presented.

In the embodiment, the flame-retardant polyester with the hollow structure is used as the carrier, so that the flame-retardant polyester not only has excellent flame-retardant performance, but also has low density due to the cavity in the flame-retardant polyester, can contain a large amount of still air and has excellent heat-insulating performance; and because a large number of cavities exist in the fiber, the fabric has good moisture and sweat permeability.

The flame-retardant polyester can also adopt a Y-shaped structure, so that the flame-retardant polyester has excellent flame-retardant performance, and has the advantages that the surface area is large, three obvious grooves are formed in the surface of the fiber, and a large number of micro pores are formed in the surface of the fiber, so that the fiber has an excellent wicking function, can quickly absorb sweat, and can be guided out through the three groove structures, and the flame-retardant polyester has a good moisture absorption and sweat guiding function.

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. Therefore, the secondary wrapping yarn consisting of the pre-oxidized fibers, the mudar fibers and the water-soluble vinylon wrapped on the peripheries of the mudar fibers and the pre-oxidized fibers is used as the filling yarn, so that the defect of low spinnability of the mudar fibers is overcome, and the filling yarn has excellent mechanical property and spinnability while having excellent antibacterial and sweat-absorbing properties.

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.

This embodiment is based on the protruding three-dimensional rectangular array arrangement structure in part of the class air cushion membrane of fabric, utilizes the excellent fire-retardant function of absorption of pre-oxidized silk, and fluffy calotropis gigantea fibre has increased adsorbable space in addition, and both carry out the synergistic promotion of function, further promote the adsorption efficiency of fabric, and its effective effect area that exerts adsorption efficiency is far greater than the adsorption effect area of carbon package commonly used among the prior art. The limit oxygen index LOI of the washable automobile purification interior fabric is not less than 32, the saturated adsorption capacity to benzene is 63.81mg/g, and the saturated adsorption capacity to toluene is 68.81 mg/g.

As shown in fig. 4 and 5, the water-soluble vinylon fibers have a certain shrinkage performance in water, so that the first structural area and the second structural area of the fabric shrink to a certain extent while removing the fiber, and the protrusion degree of the air cushion-like film structure is further promoted, so that the fabric prepared in the embodiment can generate a significant protrusion effect on the surface of the fabric, the double-layer part of the first structural area is in local contact with a human body, which is different from the traditional cushion fabric plane, and meanwhile, the air flow conduction channel can be formed due to the local protrusion state, so that the air permeability is good, and the fabric is firm and wear-resistant. Therefore, the fabric prepared by the embodiment guarantees the comfort of the fabric for the automotive interior, and meanwhile, the fabric is endowed with excellent adsorption flame-retardant function, moisture absorption and sweat conduction function and water washability.

And the surface formed by the flame-retardant polyester faces outdoors, so that the characteristics of good chemical stability, long service life and sunlight resistance of the polyester can be fully expressed. By introducing the functional filling weft yarn, the kapok fiber has the unique structure of large and hollow cell walls and the advantage of low conductivity, so that the fabric has good sound insulation and sound absorption functions, and the fabric with the functions of antibiosis and sound absorption is obtained. And after the subsequent air washing mode is adopted and the fiber is subjected to the fiber removal treatment, the kapok fibers are untwisted uniformly and are distributed in the surface layer fabric and the inner layer fabric in a fluffy manner, and the formed local convex three-dimensional rectangular array arrangement structure synergistically promotes the sound insulation and absorption functions of the fabric.

Please refer to fig. 1, fig. 6-8 and table 4 for the analysis of the results of example 4:

as shown in fig. 6, (a) in fig. 6 is a front view of the fabric, (b) in fig. 6 is a back view of the fabric, and the fabric prepared in example 4 is white, wherein the first structure region of the fabric is composed of a surface weave and a back weave of a twill weave structure, the second structure region is composed of a surface weave and a back weave of a twill weave structure through binding and binding, a local raised three-dimensional rectangular array arrangement structure of the air cushion-like film is presented through the binding of the two structure regions, and the fabric structure is flat and convenient to weave.

In example 4, the antistatic fabric for high-end wear, which can be washed, softened and comfortable, is prepared by using hemp roving, conductive metal wires and water-soluble vinylon filaments wrapped on the surfaces of the hemp roving and the conductive metal wires to form the weft yarn for the pad, obtaining the weft yarn for the pad with three functions of moisture absorption, moisture storage and conductivity based on the high moisture absorption and moisture conduction characteristics of hemp and the good conductivity and weavability of the conductive metal wires, and dissolving the water-soluble vinylon filaments in a washing and charging manner so that the hemp fibers and the conductive metal wires are uniformly filled and fluffy in the closed double-layer structure of the first structural area of the fabric, and adding the comfort of the cotton yarn and the moisture absorption of the polyester.

The principle of eliminating static electricity of the antistatic fabric is as follows: based on both charge leakage and neutralization mechanisms. When grounded, static electricity on the fabric can be discharged to the ground through the conductive fibers in addition to being neutralized by corona discharge of the conductive fibers; when not grounded, the electricity is eliminated by means of weak corona discharge of the conductive fibers. The conductive metal wires are added into the fabric, so that the fabric has excellent conductivity, static electricity on a human body is discharged through the conductive metal wires, and local accumulation of the static electricity is effectively prevented.

It is found that, when the second structure region is a single-layer structure, the local raised three-dimensional rectangular array arrangement structure of the air cushion-like film is formed by the connection of the two structure regions, which is more stable and more three-dimensional than the double-layer structure in embodiment 4.

Example 6

The embodiment provides a method for preparing a flexible fabric with an infrared stealth function of an air cushion film-like structure, which is different from the method in embodiment 1 in that: the fabric structure design and the weaving process parameters are different, as shown in table 6, and other steps are substantially the same, and are not described herein again.

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 the fabric of example 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 walls are thin, the longitudinal surface is provided with micro convex marks, and the cross section is circular orThe oval hollow structure has the characteristics of large heat capacity and low conductivity, so that the heat insulation plate 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. In the present invention, Fe is used₃O₄Kapok 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 prepared 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.

Compared with the example 6, the fabric prepared in the comparative example 3 has a certain thermal infrared stealth effect, but in practical application, the coating layer increases the weight of the material, and the coating layer is easy to fall off, poor in wearability, not resistant to water washing and difficult to meet military requirements.
