Description

Technical Field

[0001] The invention relates to the field of textiles, and in particular to a fabric with an air cushion membrane structure and a preparation method thereof. Background Art

[0002] With the development of society, people have higher and higher requirements for the appearance and functionality of textiles. Functional textiles have shown an increasingly broad development space, and their applications have gradually penetrated into practical fields such as clothing, decoration, military, and construction. At present, the research on functional textiles is no longer limited to a specific function, but tends to develop in the direction of multi-function, high function and composite function. At the same time, with the continuous emergence of functional yarns such as antistatic, flame retardant, one-way sweat guide, UV resistance, moisture absorption and quick drying, phase change temperature regulation, infrared stealth, antibacterial, and electromagnetic shielding, it provides a basis for the design and development of multifunctional fabrics with different structures. The development of protective equipment, medical fabrics, safe and durable transportation and construction fiber materials, and high-performance composite fiber materials has shown people a huge development space for functional textiles.

[0003] In today's scientific research and industrial production, multifunctional fabrics have been successfully designed and developed and applied to life. However, most of these multifunctional fabrics are first interwoven with functional yarns, and then post-processed with functional finishing agents to obtain a variety of functional properties. This technical method is simple and low in cost. The attached functional components are in direct contact with the skin and are directly impacted by external forces during washing, which will accelerate the trend of weakening their functions. In addition, the feel and comfort of the products prepared from this fiber are not good. Therefore, the use of a variety of functional yarns combined with weaving technology is the trend of developing functional textiles. It is also an effective way to improve the defects of functional textiles such as single function, poor comfort, and poor durability.

[0004] The double-layer fabric with double-layer structure prepared by weaving technology has two sets of independent warp yarn systems (surface warp and inner warp) and two sets of independent weft yarn systems (surface weft and inner weft) interwoven to form overlapping upper and lower layers. The double-layer structure can be used to increase the thickness and strength of the fabric, and the fabric is soft and fluffy, has excellent moisture absorption, and has strong shape variability.

[0005] The invention patent with application number CN201610528454.5 discloses a method for producing a thermal-storage and heat-generating expanded double-layer structure yarn thermal woven fabric. In the production process, the yarns are selected from thermal-storage and heat-generating fibers, regenerated cellulose fibers, high-shrinkage acrylic fibers, water-soluble vinyl staple fibers and four-in-one blended core-spun double-layer structure yarns. The fabric structure is woven using a double weft structure. The prepared fabric has triple thermal insulation functions such as thermal-storage and heat-generating fibers, internal hollowness of the double-layer structure yarn, and double-sided fabric, which greatly improves the thermal insulation effect of the woven fabric.

[0006] The invention patent with application number CN201710078665.8 discloses a preparation process of a unidirectional moisture-conducting, lightweight, warm woven double-layer fabric, in which a double-layer structure woven fabric is prepared, in which the warp yarn is interwoven with the surface weft by the "inner warp binding" method, and the surface layer adopts one of polyester special-section water-absorbing fibers or cool silk cotton fibers, and the inner layer adopts polypropylene hollow fiber colored yarn. One side of the fabric is hydrophobic and moisture-conducting, and the other side absorbs water and discharges moisture, thereby enabling the fabric to obtain the function of unidirectional moisture conduction.

[0007] The invention patent with application number CN201910240009.2 discloses a design method and production process of a double-layer quick-drying three-proof fabric. It selects hollow polyester / modal blended yarn and modal / coolmax fiber blended yarn, and uses a double-layer structure to make the fabric relatively thick, thereby improving the warmth retention effect of the fabric. The air between the two layers of fabric is not easy to flow, which can further improve the warmth retention performance of the fabric.

[0008] The invention patent with application number CN201811353581.1 discloses a design method and production process of a double-layer moisture-permeable and thermal insulation fabric. The prepared fabric is a double-layer fabric, which uses the process technology of changing the inner and outer layers of the fabric to achieve the connection between the upper and lower layers. The yarn is made of a blend of polyester and Tencel with a special structure. The prepared fabric has excellent moisture permeability and thermal insulation functions.

[0009] Although the fabrics prepared by the above methods all adopt a double-layer structure and select yarns with specific functions and specific structures to prepare functional textiles, due to the structural limitations of the double-layer fabrics and the functional limitations of the selected yarns, the functions of the prepared textiles are not greatly improved, and the service life is not long. The functional yarns are prone to wear and failure and are not resistant to washing. Summary of the invention

[0027] Beneficial Effects

[0028] 1. The fabric of the air cushion membrane structure provided by the present invention is based on the traditional double-layer weft inlay structure, changes the structure of the weft inlay yarn, and combines the technical means of mechanical washing to achieve the washable and rechargeable performance of the fabric. In the fabric of the air cushion membrane structure provided by the present invention, the sizes of the first structural area and the second structural area can be adjusted, and the adjustment range is wide. The second structural area is connected to the first structural area with a double-layer structure by a single-layer structure structure or a double-layer binding structure. Compared with the traditional quilting method, the fabric is more stable, and the distribution of the introduced functional weft inlay yarn in the fabric is more uniform and controllable.

[0029] 2. The fabric of the air cushion membrane structure provided by the present invention has a double-layer structure in the first structural area as the main structure of the fabric, and the structure is sealed and can well protect the weft inlay yarns arranged in the double-layer structure; the structure of the second structural area plays a role in stabilizing the overall fabric structure; and the weft inlay yarns are not interwoven with the inner and outer layers in the double-layer area of ​​the first structural area, which effectively reduces the requirements for the spinnability and weavability of the weft inlay yarns, and has a wide range of applications. The fabric of the air cushion membrane structure provided by the present invention arranges the weft inlay yarns between the double-layer structure. Compared with the traditional functional yarns exposed on the fabric surface in the form of tissue points, this arrangement avoids the defects of the weft inlay yarns affecting the appearance, feel and wearing comfort of the fabric, and effectively reduces the wear of the functional yarns, which greatly improves the service life of the fabric based on the functional yarns. In addition, the fabric has excellent water resistance, which is more conducive to achieving a permanent water-resistant grade.

[0030] 3. In the fabric of the air cushion membrane structure provided by the present invention, the weft yarn is composed of short-fiber roving and water-soluble vinylon filaments wrapped around the periphery of the short-fiber roving; utilizing the water-soluble characteristics of the vinylon filaments, after the fabric is mechanically washed and filled, the short-fiber roving is untwisted and evenly dispersed in the double-layer structure of the first structural area, so that the first structural area is fluffy and raised, so that the fabric presents a locally raised three-dimensional rectangular array arrangement structure, which can better promote the specific functional characteristics of the fabric.

[0031] 4. The fabric of the air cushion membrane structure provided by the present invention is composed of a first structural area and a second structural area with different tissue structures connected to form a locally raised three-dimensional rectangular array arrangement structure. This structure will produce a convex effect on the fabric surface, that is, the first structural area is in a convex state, so that the fabric can be in point contact rather than full plane contact; the single-layer structure of the second structural area can better contrast the convex effect, or the double-layer connection structure of the second structural area can form a functional continuous conduction channel, and the two structural areas work synergistically to better promote the functional characteristics of the fabric.

[0032] 5. The fabric with an air cushion membrane structure provided by the present invention is based on a locally raised three-dimensional rectangular array arrangement structure.

[0052] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0053] The present invention provides a method for preparing a fabric having an air cushion membrane structure, comprising the following steps:

[0054] S1, fabric structure setting: determine the surface weave and lining weave of the first structural area and the weave structure of the second structural area, the weave structure adopts one of the original weave and the changed weave; select the warp yarn, weft yarn and functional weft yarn of the predetermined raw materials;

[0055] S2, weaving after drawing in the warp and reed according to the machine drawing;

[0059] Those skilled in the art should understand that in step S21, in the first structural area, the ratio of the surface warp yarn to the inner warp yarn can be one of 1:1, 2:1, 2:2, 3:1, or other ratios, which can be set according to product design needs and is not specifically limited; the ratio of the surface weft yarn to the inner weft yarn can be one of 1:1, 2:1, 3:1, 4:2, or other ratios, which can be set according to product design needs and is not specifically limited.

[0060] Similarly, in step S22, when the second structural area adopts a double-layer structure, the ratio of the surface warp yarn to the inner warp yarn and the ratio of the surface weft yarn to the inner weft yarn can be set according to product design requirements, and there is no specific limitation.

[0061] Preferably, the mechanical washing is air washing.

[0062] See also Figure 1As shown, the air cushion membrane structure-like fabric 100 is composed of a first structural area 10 and a second structural area 20 connected to form an array structure; the first structural area 10 is a double-layer structure consisting of a surface structure and a lining structure; the second structural area 20 is a double-layer structure formed by connecting the surface structure and the lining structure, or the second structural area 20 is a single-layer structure;

[0063] An inlay weft yarn is arranged between the surface tissue and the inner tissue of the first structural area 10, and the inlay weft yarn is a first wrapped yarn composed of a spun fiber roving and a water-soluble vinylon filament wrapped around the periphery of the spun fiber roving; or the inlay weft yarn is a second wrapped yarn composed of a spun fiber roving, a functional filament, and a water-soluble vinylon filament wrapped around the spun fiber roving and the functional filament;

[0064] After the fabric 100 with the air cushion membrane structure is mechanically washed and filled, the short fiber roving in the inlay weft yarn is untwisted and evenly dispersed in the double-layer structure of the first structural area 10, so that the first structural area 10 is fluffy and raised, so that the fabric 100 with the air cushion membrane structure presents a locally raised three-dimensional array structure.

[0065] Preferably, the second structural zone 20 includes a warp connection zone 21 connecting the adjacent first structural zones 10 in the warp direction and a weft connection zone 22 connecting the adjacent first structural zones 10 in the weft direction; wherein the organizational structures of the warp connection zone 21 and the weft connection zone 22 may be the same or different.

[0066] The preparation method of the fabric with the air cushion membrane structure provided by the present invention is described below in combination with Examples 1-7 and Comparative Examples 1-3:

[0067] Example 1

[0068] A method for preparing a thin and light warm-keeping fabric with an air cushion membrane structure, comprising the following steps:

[0069] S1, determine that the surface weave and the lining weave of the first structural area are both plain weave, and the second structural area is a square weave; determine that the ratio of the number of warp yarns in the first structural area and the number of warp yarns in the weft connection area of ​​the second structural area is 4:1; determine the materials of the warp yarns, weft yarns and weft inlay yarns in the first structural area and the second structural area (as shown in Table 1);

[0070] S2, according to the machine diagram (such as Figure 2 Weaving is carried out after drawing in the warp and reed (as shown);

[0071] In the first structural area, the yarn arrangement ratio of the surface warp yarn to the inner warp yarn is 1:1;

[0072] Wherein, in the first structural area, the in-lay weft yarn does not participate in interweaving, but is only padded between two layers of tissue of the double-layer tissue structure; in the second structural area, the in-lay weft yarn participates in interweaving.

[0073] S3, after weaving is completed, the fabric is air-washed to untwist the infill weft yarns in the first structural area, and then evenly dispersed and filled in the first structural area, so that the first structural area is convex, and a fabric with an air cushion membrane structure is obtained.

[0074] During the weaving process, the weaving process parameters and raw material settings are shown in Table 1 below.

[0075] Table 1 Organization structure design and weaving process parameter settings of Example 1

[0076]

[0077] The fabric prepared in the embodiment 1, wherein the first structural area of ​​the fabric is a double-layer structure, and both the surface structure and the inner structure are plain weaves; the warp connection area and the weft connection area of ​​the second structural area are both single-layer structures, which are composed of square plain weaves. The fabric connects the double-layer structure of the first structural area in the warp and weft directions through the warp connection area and the weft connection area, respectively, so that the second structural area forms a flat and stable single-layer connection channel in the warp and weft directions. In the double-layer structure of the first structural area, the weft yarn is lined between the surface and inner layers of the fabric; after air washing and filling, due to the de-fiberization of the water-soluble vinylon filaments, the PI staple fibers in the weft yarn are filled in the double-layer structure as loose fibers and are fluffy and distributed, so that the double-layer structure area is bubbled, presenting a locally raised three-dimensional rectangular array arrangement structure similar to an air cushion membrane. In addition, the water-soluble vinylon filaments have a certain shrinkage effect in water, which causes the first structural area and the second structural area of ​​the fabric to shrink to a certain extent while degenerating, thereby increasing the thickness of the fabric, further promoting the convexity of the air cushion membrane structure, and effectively improving the warmth and heat insulation effect of the fabric.

[0078] Among them, the thermal conductivity of polyimide material (PI) is 0.031W / (m·k), while the thermal conductivity of wool is 0.029W / (m·k); that is, PI is similar to wool and has excellent thermal insulation effects. In Example 1, PI and cotton are used as the main raw materials. After the configuration of the yarn, the main raw material of the fabric layer formed on the contact surface with the outside world is cotton, giving the fabric a good hand feel; the fabric layer facing the human body is PI, which can effectively reduce the heat transfer between the human body and the environment, and provide a good warm insulation effect. Experiments show that through the preparation method of Example 1, a washable, light and warm fabric with a good hand feel can be prepared, and its thermal resistance value is 0.158m 2 ℃ ·W -1 .

[0079] It should be noted that in this embodiment, the warp connection area and the weft connection area have the same organizational structure, but those skilled in the art should understand that the organizational structure of the warp connection area and the weft connection area may also be different according to the design and application requirements of the product. Figure 1 It is only for the convenience of distinguishing the warp connection area from the weft connection area, so the different filling patterns used do not mean that the structures of the warp connection area and the weft connection area are different.

[0080] Comparative Example 1

[0081] The difference between Comparative Example 1 and Example 1 is that the water-soluble vinylon filaments in the weft inlay yarn are replaced with water-insoluble vinylon filaments, and the other steps are basically the same as those in Example 1, which will not be repeated here. Since the weft inlay yarn is wrapped with water-insoluble vinylon filaments, during the air washing and filling process of step S3, the weft inlay yarn continues to be inserted between the two layers of fabric in the first structural area in the form of water-insoluble vinylon filaments wrapped with PI staple rovings, and participates in the interweaving in the second structural area in the form of water-insoluble vinylon filaments wrapped with PI staple rovings. It can be seen from the test that the thermal resistance value of the prepared comparative sample is 0.078m 2 ℃ ·W -1 , which is significantly lower than the thermal resistance value of Example 1 (0.158m 2 ℃ ·W -1 ).

[0082] It can be seen that in Example 1, by wrapping the short fiber roving with water-soluble vinylon filaments, when the fabric is air-washed, the vinylon filaments are dissolved due to the water solubility of the water-soluble vinylon filaments, so that the short fiber roving is disintegrated and fluffy and distributed between the two layers of fabric in the form of fibers, and the three-dimensional rectangular array arrangement structure of the local protrusions of the air cushion membrane of the fabric can effectively improve the warmth retention of the fabric, and can be used to prepare a light, comfortable and warm fabric. In addition, the fabric has a flat structure and is easy to weave.

[0083] Example 2

[0084] This embodiment provides a method for preparing a washable automobile purification interior fabric with an air cushion membrane structure. Compared with Example 1, the difference lies in the difference in fabric structure, raw materials and weaving process parameters between the first structural area and the second structural area, as shown in Table 2. The other steps are basically the same and will not be repeated here.

[0085] Table 2 Organization structure design and weaving process parameter settings of Example 2

[0086]

[0087]

[0088] See also Figure 3-5 And Table 2 analyzes Example 2:

[0089] Figure 3 This is a picture of the fabric on the machine of Example 2 of the present invention. Figure 4 As shown, in the fabric prepared in Example 2, the first structural area is composed of a surface weave and a back weave of a twill weave structure, and the second structural area is a single-layer weave structure of a twill weave structure.

[0090] The main yarn material of Example 2 is flame-retardant polyester, and functional weft yarn composed of ox-horn melon roving and pre-oxidized yarn and water-soluble vinylon filament wrapped on the surface is introduced into the double-layer fabric. Through subsequent air washing, the pre-oxidized yarn with adsorption flame retardant function and the ox-horn melon fiber with antibacterial and sweat absorption properties are evenly dispersed between the surface layer and the inner layer of the first structural area of ​​the fabric, presenting a local convex three-dimensional rectangular array arrangement structure similar to an air cushion membrane.

[0091] In this embodiment, flame-retardant polyester with a hollow structure is used as a carrier, which not only has excellent flame-retardant properties, but also has excellent thermal insulation properties due to the presence of cavities inside, low density, and the ability to contain a large amount of still air; and because there are a large number of cavities inside the fibers, it has good moisture permeability and sweat conduction functions.

[0092] It should be noted that the flame-retardant polyester can also adopt a Y-shaped flame-retardant polyester, which not only has excellent flame-retardant properties, but also has a large surface area, three obvious grooves on the fiber surface, and a large number of micro-pores on the fiber surface. This structure enables the fiber to have excellent wicking function, can quickly absorb sweat, and conduct sweat through the three groove structures, and has good moisture absorption and sweat conduction function.

[0093] In the present embodiment, since the caltrop fiber has a unique morphological structure, has a high hollowness, good warmth retention, good hygroscopicity, and excellent antibacterial efficacy, the caltrop fiber itself has disadvantages such as low strength, no bending, easy brittle breakage, and poor cohesion, which are not conducive to spinning, limiting its scope of use. Water-soluble vinyl fiber is a functional differentiated fiber with good spinnability and ideal water solubility, and is non-toxic, tasteless, transparent, and naturally biodegradable after being dissolved in water. Therefore, the present invention uses a second wrapped yarn composed of pre-oxidized silk, caltrop fiber, and water-soluble vinyl wrapped around the caltrop fiber and the pre-oxidized silk as the weft inlay yarn, which overcomes the defect of low spinnability of caltrop fiber, so that the weft inlay yarn has excellent antibacterial and sweat absorption properties, as well as excellent mechanical properties and spinnability.

[0094] Among them, water-soluble vinylon fiber is used as a co-spinning, and the woven fabric is subjected to post-retrieval finishing. During the retrieval process, the water-soluble vinylon fiber in the yarn is dissolved and removed, leaving only the pre-oxidized silk and ox-horn melon fiber, and the weft yarn changes from yarn to loose fiber, and then is dried and finished, making the yarn structure fluffy, the fabric presents a fluffy, soft and comfortable feeling, and improving the fluffiness of the air cushion membrane structure of the fabric, thereby making the convex structure of the fabric significant, and its high softness, realizing the function of washability and rechargeability.

[0095] This embodiment is based on the air cushion film-like local raised three-dimensional rectangular array arrangement structure of the fabric, and utilizes the excellent adsorption and flame retardant function of the pre-oxidized silk, and the fluffy ox-horn melon fiber increases the adsorption space. The two promote the synergy of function and further improve the adsorption performance of the fabric. The effective area of ​​the adsorption function is much larger than the adsorption area of ​​the commonly used carbon bag in the prior art. The limiting oxygen index LOI of the washable car purification interior fabric is ≥32, the saturated adsorption capacity of benzene is 63.81 mg / g, and the saturated adsorption capacity of toluene is 68.81 mg / g.

[0096] like Figure 4 and Figure 5 As shown, since the water-soluble vinyl fiber has a certain shrinkage property in water, the first structural area and the second structural area of ​​the fabric shrink to a certain extent while degenerating, further promoting the convexity of the air cushion membrane structure. Therefore, the fabric prepared in this embodiment will produce a significant convex effect on the fabric surface. The double-layer part of the first structural area is in partial contact with the human body, which is different from the full contact of the traditional cushion fabric plane. At the same time, the local convex state can form an air flow channel, which has good air permeability, and the fabric is firm and wear-resistant. It can be seen that the fabric prepared in this embodiment ensures the comfort of the fabric for automobile interior while giving the fabric excellent adsorption and flame retardancy, moisture absorption and sweat conduction function and washability.

[0097] Example 3

[0098] This embodiment provides a method for preparing a household textile fabric with an air cushion membrane structure having sound insulation and sound absorption functions. Compared with Example 1, the difference lies in: the fabric structure design and weaving process parameters are different, as shown in Table 3. The other steps are basically the same and will not be repeated here.

[0099] Table 3 Organization structure design and weaving process parameter settings of Example 3

[0100]

[0101] The air cushion structure fabric with flax / flame-retardant polyester as the main fiber of this embodiment is a high-end household textile fabric that can make flax fiber and flame-retardant polyester fiber respectively exert and reflect their excellent physical and chemical properties. When used as a curtain, the side composed of flax faces indoors, so that the advantages of flax fiber such as hygroscopicity and air permeability are prominent, reflecting the natural style of natural flax fiber that is not easy to get dirty and has a soft luster; flax fiber has a broad-spectrum antibacterial property, and can emit a fragrance that has a strong inhibitory effect on the growth of bacteria, and also has a strong killing power against mites. The side composed of flame-retardant polyester faces outdoors, which can fully demonstrate the characteristics of polyester with good chemical stability, long service life, and resistance to sunlight. By introducing functional weft yarn, since kapok fiber has a unique structure with a large hollow cell wall and the advantage of low conductivity, the fabric has good sound insulation and sound absorption functions, thereby obtaining a fabric with both antibacterial and sound absorption functions. And through the subsequent air washing method, after the fiber removal treatment, the kapok fibers are evenly untwisted and fluffy distributed in the surface and inner layers of the fabric. The formed local raised three-dimensional rectangular array arrangement structure synergistically promotes the sound insulation and sound absorption function of the fabric.

[0102] Experiments show that the air cushion membrane structure of the home textile fabric with sound insulation and sound absorption function prepared in this embodiment has an afterburning time of 3.80s, a smoldering time of 0.31s, and a damaged length of 93mm. According to the GB / T17591-2006 standard for decorative fabrics, the damaged length of B1 grade is ≤150mm and the afterburning time is ≤5s, so it can be seen that the home textile fabric meets the B1 grade standard.

[0103] The antibacterial performance test of the home textile fabric prepared in this embodiment is as follows: the antibacterial rate of the home textile fabric against Escherichia coli is 81%, the antibacterial rate against Staphylococcus aureus is 83%, and the antibacterial rate against Candida albicans is 71%. Moreover, flax fiber is a natural antibacterial material, and there is no problem of silver ion precipitation. According to the antibacterial evaluation of GB / T20944.3-2008: the antibacterial rate against Staphylococcus aureus and Escherichia coli is greater than or equal to 70%, which can be evaluated as having antibacterial effects on Staphylococcus aureus and Escherichia coli; the antibacterial rate against Candida albicans is greater than or equal to 60%, which can be evaluated as having antibacterial effects on the bacteria; it can be seen that the home textile fabric prepared in this embodiment has excellent antibacterial performance.

[0104] Example 4

[0105] This embodiment provides a method for preparing an antistatic workwear fabric with an air cushion membrane structure, comprising the following steps:

[0106] S1, determine that the surface weave and the inner weave of the first structural area are both twill weave, and the second structural area is a double-layer weave of knotted warp; determine the materials of the warp yarn, weft yarn and weft inlay yarn of the first structural area and the second structural area (as shown in Table 4), and the weft inlay yarn is a second wrapped yarn composed of hemp roving, conductive metal wire and water-soluble vinylon filaments wrapped around the hemp roving and the conductive metal wire;

[0107] S2, according to the machine diagram (such as Figure 8 Weaving is carried out after drawing in the warp and reed (as shown);

[0108] S21, in the first structural area, the yarn arrangement ratio is: the ratio of the surface warp yarn to the inner warp yarn is 1:1;

[0109] S22, in the double-layer structure of the second structural area, the yarn arrangement ratio of the surface warp yarn to the inner warp yarn is 1:1;

[0110] Wherein, in the first structural area, the in-lay weft yarn does not participate in interweaving, but is only padded between the two layers of the double-layer tissue structure; in the second structural area, the in-lay weft yarn is only padded between the connected double-layer tissues, and does not participate in interweaving.

[0111] S3, after weaving is completed, the fabric is air-washed and filled, so that the infill weft yarns in the first structural area are untwisted, evenly dispersed and filled in the first structural area, so that the first structural area is convex, and a fabric with an air cushion membrane structure is obtained.

[0112] During the weaving process, the weaving process parameters and raw material settings are shown in Table 4.

[0113] Table 4 Organization structure design and weaving process parameter settings of Example 4

[0114]

[0115] See also Figure 1 , Figure 6-8 And Table 4 analyzes the results of Example 4:

[0116] like Figure 6 As shown, Figure 6 (a) is the front view of the fabric. Figure 6 (b) is the back view of the fabric. The fabric prepared in Example 4 is white, wherein the first structural area of ​​the fabric is composed of the surface tissue and the inner tissue of the twill structure, and the second structural area is composed of the surface tissue and the inner tissue of the twill structure through the warp stitching. Through the connection of the two structural areas, a local raised three-dimensional rectangular array arrangement structure similar to an air cushion membrane is presented, and the fabric structure is flat and easy to weave.

[0117] In Example 4, hemp roving, conductive metal wire and water-soluble vinylon filaments wrapped on the surface thereof are used to form the weft padding yarn. Based on the high moisture absorption and moisture conductivity of hemp, the good conductivity and weavability of the conductive metal wire, the weft padding yarn with the three functions of moisture absorption, moisture storage and conductivity is obtained. The water-soluble vinylon filaments are dissolved in a washable and rechargeable manner, so that the hemp fibers and the conductive metal wires are evenly filled and fluffy and dispersed in the closed double-layer tissue of the first structural area of ​​the fabric. Combined with the comfort of cotton yarn and the hygroscopicity of polyester, a washable, soft and comfortable high-end antistatic fabric for clothing is prepared.

[0118] The principle of antistatic fabric to eliminate static electricity is based on two mechanisms: leakage and neutralization of charge. When grounded, the static electricity on the fabric is not only neutralized by the corona discharge of the conductive fiber, but also discharged to the ground through the conductive fiber; when not grounded, the static electricity is eliminated with the help of the weak corona discharge of the conductive fiber. Adding conductive metal wire to the fabric makes the fabric have excellent conductivity. The conductive metal wire discharges the static electricity on the human body through the conductive wire, effectively preventing the local accumulation of static electricity.

[0119] In Example 4, ultra-fine polyester filaments are used, which have excellent sweat-conducting properties. With this arrangement, the outer tissue and the inner tissue cooperate with each other, that is, the inner tissue absorbs sweat, and the outer tissue guides the sweat away, and the sweat is introduced into the functional weft yarn in the first structural area. Due to the conductivity of sweat, the conductive metal wire is connected to synergistically enhance the conductive properties of the fabric. The conductive metal wire in the weft yarn achieves continuous conductivity in the weft direction of the fabric. Figure 7 As shown, when the fabric is connected to the light emitting diode, the light emitting diode can light up (such as Figure 7 Middle A, Figure 7 Middle B, Figure 7 As shown in C), it is confirmed that the fabric has a continuous conductive channel in the weft direction and has excellent antistatic properties; and the conductive metal wire in the fabric is padded between the double layers of fabric, does not participate in interweaving, and does not directly contact and rub with the outside world, so it is protected, thereby extending the service life of the conductive metal wire.

[0120] Comparative Example 2

[0121] According to the prior art, hemp, conductive metal wire, cotton yarn and polyester filament are directly blended and woven to prepare a fabric with antistatic function.

[0122] Comparing comparative example 2 with example 4, the fabric prepared in comparative example 2 has the defect of partial conductivity, and the fabric strength and comfort are low. Moreover, the direct blending of hemp, conductive metal wire, cotton yarn and polyester filament will reduce the physical properties and heat resistance of the fiber. Compared with comparative example 2, the fabric prepared in example 4 has excellent overall conductivity (such as Figure 7As shown), and based on the locally raised three-dimensional structure, the fabric has high comfort and wear resistance; and the weft yarn in the fabric is between the double-layer structure, is not easily damaged by wear and tear, is washable, and extends the service life of the fabric.

[0123] Example 5

[0124] This embodiment provides a method for preparing an antistatic workwear fabric with an air cushion membrane structure. The difference from Embodiment 4 is that the fabric structure design and weaving process parameters are different, as shown in Table 5. The other steps are basically the same and will not be repeated here.

[0125] Table 5 Organization structure design and weaving process parameter settings of Example 5

[0126]

[0127] See also Figure 9-10 And Table 4-5 analyzes Example 4-5:

[0128] Fig. 9 The fabric structure diagram of Example 5. Experiments show that when the second structural area is a single-layer structure, the connection of the two structural areas presents a three-dimensional rectangular array structure of local protrusions similar to an air cushion membrane. Compared with the double-layer joint structure in Example 4, its structure is more stable and the local protrusion structure is more three-dimensional and intuitive.

[0129] like Fig.10 As shown, from the warp section diagram of the fabric structure, the first structural area of ​​the fabric ( Fig.10 As shown in A), the second structural region ( Fig.10 The alternating structure (shown in B) constitutes an electrostatic anti-aggregation structure similar to a "pearl chain". The double-layer fabric structure in the first structural area is like a "pearl", which is filled with antistatic functional weft yarns with strong hygroscopicity to absorb sweat from the surface of the skin, while the connecting part in the second structural area is like a "chain", which plays a role in conducting away the charge in time.

[0130] Example 6

[0131] This embodiment provides a method for preparing a flexible fabric with an air cushion membrane structure and infrared stealth function. Compared with Example 1, the difference lies in: the fabric structure design and weaving process parameters are different, as shown in Table 6. The other steps are basically the same and will not be repeated here.

[0132] Table 6 Organization structure design and weaving process parameter settings of Example 6

[0133]

[0134] See also Figure 11-16And Table 6 analyzes Example 6:

[0135] Fig.11 This is a fabric machine drawing of Example 6 of the present invention. Figure 12-13 As shown, in this embodiment, by introducing functional short fiber rovings mixed with basalt fiber and Fe3O4-kapok yarn and functional weft yarns composed of water-soluble vinylon filaments, after air washing and fiber removal treatment, the prepared fabric can give full play to the infrared stealth function of the material while taking into account the water washability. Further, the designed fabric is dyed by introducing reducing dyes to absorb nearby infrared light waves, giving the fabric good wearability and infrared stealth performance. Therefore, it can be widely used in military occasions to achieve thermal infrared stealth functions under different conditions.

[0136] Among them, reducing dyes are insoluble in water. When dyeing, they must be reduced and dissolved in alkaline strong reducing solution to become leuco sodium salts before they can be dyed on the fiber. After oxidation, they are restored to insoluble dye lakes and fixed on the fiber, with high washing and light fastness. The purpose of introducing reducing dyes is to meet the requirements of compatibility with visible light invisibility. In addition to high strength, electrical insulation, corrosion resistance, high temperature resistance and other excellent properties, basalt continuous fibers also have excellent wave absorption and wave transmission properties.

[0137] Kapok fiber has a unique structure of a large hollow cell wall, that is, the cell wall is relatively thin, there are tiny convex marks on the longitudinal surface, and the cross section is a circular or elliptical hollow structure. It has the characteristics of large heat capacity and low conductivity, which makes it have a good heat insulation effect. After wrapping an object with kapok fiber fabric, it can reduce the infrared radiation emitted by the object, reduce the heat conduction to the outside, reduce the infrared radiation intensity of the object, make the infrared characteristics of the target and the background similar, and achieve low infrared detectability. The present invention uses Fe3O4-kapok blended yarn, which combines the excellent adsorption performance of functional Fe3O4 particles and the heat insulation and infrared radiation reduction performance of kapok fiber, and greatly improves the infrared stealth function of the functional weft yarn.

[0138] like Fig.12As shown, the fabric prepared in Example 6, the first structural area is composed of the surface tissue and the inner tissue, and the second structural area is composed of the surface tissue and the inner tissue through the warp connection structure. Through the connection of the two structural areas, a three-dimensional rectangular array arrangement structure of local protrusions similar to an air cushion membrane is presented. On the one hand, the infrared stealth function pad weft yarn located in the double-layer fabric part of the first structural area is untwisted and evenly distributed in the surface and inner layers of the fabric through subsequent air washing, which effectively improves the service life of the stealth function fiber material. On the other hand, the unique hollow structure of kapok fiber effectively accommodates the functional material particles Fe3O4 and forms protection. Based on the above two points, while ensuring the comfort of the stealth fabric, the water washability and wear resistance of the infrared stealth fabric are achieved. And when wearing, the double-layer protrusion formed in the first structural area is in point contact with the human body, and the double-layer knotted warp structure in the second structural area can form an air flow conduction channel, which is conducive to the derivation of moisture.

[0139] Fig.13 This is a simulated effect diagram of the fabric prepared in Example 6 being applied to military equipment and military clothing. Fig.14 As shown, at room temperature, Fig.14 The water temperature in beaker B is 71.5℃ ( Fig.14 (shown in the infrared camera photo in center A). Fig.15 It is shown that the beaker is covered with the fabric with stealth function woven by this embodiment ( Fig.15 When infrared photography was performed, it was found that the infrared light emitted by the hot water was greatly reduced, and the temperature at the calibration center was only 28.1°C ( Fig.15 (as shown in A). Fig.16 It can be seen that when the fabric with stealth function woven in this embodiment is subjected to infrared spectrum test, the infrared spectrum has been basically absorbed, which further proves the excellent infrared stealth function of the fabric.

[0140] Comparative Example 3

[0141] The fabric is prepared by coating infrared stealth material in a traditional way to achieve stealth function. The infrared stealth material is composed of basalt powder, granular Fe3O4 and auxiliary materials. Compared with Example 6, the fabric prepared in Comparative Example 3 has a certain thermal infrared stealth effect, but in actual application, the coating makes the material heavier, and the coating is easy to fall off, the wearing performance is poor, and it is not washable, which is difficult to meet military needs.

[0142] Example 7

[0143] This embodiment provides a method for preparing a wall cloth with an air cushion membrane structure. Compared with Example 3, the difference lies in that the functional pad weft yarn selected is different. This embodiment uses a functional pad weft yarn with excellent adsorption properties composed of bamboo charcoal regenerated fiber roving and water-soluble vinylon filaments. The other steps are the same and will not be repeated here.

[0144] In the air cushion membrane-like fabric structure designed and woven in this embodiment, the double-layer structure in the first structural area serves as the main structure of the fabric, and the single-layer structure in the second structural area plays a role in stabilizing the fabric structure; and the functional pad weft yarn is not interwoven with the inner and outer layers in the double-layer area of ​​the first structural area, which effectively reduces the requirements for the weavability of the functional yarn while ensuring the service life of the functional yarn and does not affect the decorative appearance of the wall cloth fabric.

[0145] When the fabric woven in this embodiment is used as a wall cloth, the side made of linen faces the room, and the side made of flame-retardant polyester is in contact with the wall. The natural color of the linen fabric and the unique weave of the woven fabric form a good decorative effect. At the same time, the good moisture absorption and antibacterial properties of the linen fiber can improve the indoor microclimate. The good affinity of polyester with the adhesive makes the adhesion fastness good, which overcomes the weakness of natural fiber wall cloth that has good performance but insufficient fastness and is not easy to paste. At the same time, it overcomes the limitation of bamboo charcoal regenerated fiber being woven and used alone. By introducing bamboo charcoal regenerated fiber yarn, the fabric has excellent antibacterial, adsorption and deodorization, heat generation, negative ion and antistatic properties. The fabric releases more than 650 negative ions / cm 3 The adsorption effect of ammonia is greater than 70%, and it works synergistically with flax fiber to effectively improve the indoor microclimate environment and enhance the quality of the living environment.

[0146] It should be noted that those skilled in the art should understand that in the fabric of the air cushion membrane structure, the surface tissue and the inner tissue may also be other original tissues or modified tissues.

[0147] The inlay yarn may also be a short-staple roving blended yarn having other specific functions.

[0148] In one weaving cycle of the fabric of the air cushion membrane structure, the sizes of the first structural area and the second structural area can be adjusted in a wide range according to functional and structural requirements.

[0149] In summary, the present invention provides a fabric of a quasi-air cushion membrane structure and a preparation method thereof. The fabric of the quasi-air cushion membrane structure is composed of a first structural area and a second structural area alternately connected in parallel to form a rectangular array arrangement structure; the first structural area is a double-layer tissue structure; the second structural area is a double-layer tissue structure formed by bonding, or the second structural area is a single-layer tissue structure; a weft pad is arranged between the double-layer tissues of the first structural area; the fabric of the quasi-air cushion membrane structure presents a locally raised three-dimensional rectangular array arrangement structure after mechanical washing and filling, and the weft pad is not interwoven with the inner and outer layers in the double-layer area of ​​the first structural area, which effectively reduces the requirements for the spinnability and weavability of the weft pad. At the same time, the weft pad is arranged between the double-layer tissues. Compared with the traditional functional yarn exposed on the fabric surface in the form of tissue points, this arrangement avoids the defects of the weft pad affecting the appearance, feel and wearing comfort of the fabric, and effectively reduces the wear of the functional yarn, which greatly improves the service life of the fabric based on the functional yarn; in addition, the fabric has excellent water resistance, which is more conducive to achieving a permanent water-resistant grade. The air cushion membrane structure fabric provided by the present invention can realize different functional requirements of the fabric by selecting weft yarns with different functional characteristics, and has great application potential and development space. The preparation method provided by the present invention has strong controllability and can realize large-scale industrial production.

[0150] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
