Description

Technical Field

[0001] The invention relates to the field of textile technology, and in particular to a flexible interwoven structure luminous fabric capable of changing a light path and a preparation method thereof. Background Art

[0002] According to the different luminous materials, luminous fabrics can be divided into three categories: luminous luminous fabrics woven from luminous materials; luminous fabrics made by integrating light-emitting diodes and textiles; fiber-optic luminous fabrics woven with optical fibers. Fiber-optic luminous fabrics are soft and comfortable, electrically insulating, and do not generate heat. They are widely used in clothing, decoration, medical treatment, safety warnings, and flexible displays. In recent years, fiber-optic luminous fabrics have gradually attracted the attention of domestic and foreign researchers, and more and more research has been conducted on the preparation methods and application fields of fiber-optic luminous fabrics.

[0003] Textile fabrics that use optical fiber as a material to achieve the purpose of luminescence mainly include end-face luminescence, full-body luminescence, and side-lighting. At present, the methods commonly used to achieve the side-lighting effect of end-face luminous optical fiber include mechanical destruction, chemical solvent corrosion, and laser treatment. The side-lighting is achieved by destroying the surface of the optical fiber or using bending to change the total reflection path of the light so that the transmitted light leaks out from the side. The defect is that the luminescence effect may be reduced due to scratches, cracks, gaps, and stains on the surface of the optical fiber. Full-body luminous optical fiber requires a certain proportion of uniformly distributed second-phase additives to be injected into the core material so that its size is distributed within a certain range. A part of the light beam injected from the end face of the optical fiber and irradiated to its surface can be reflected outside the skin material to produce a full-body luminous effect. However, single-core full-body luminous optical fiber will become hard and brittle when the ambient temperature is too low. The use length is usually not more than 30m, which is not conducive to weaving. The preparation methods of side-emitting optical fiber mainly include cone-surface incidence method, damage core-skin structure method, optical fiber braiding method, adding special additives to optical fiber core or skin material, optical fiber multi-cladding method, changing core-skin refractive index structure method, changing core diameter method and skin crystallization method, which can realize optical fiber side-emitting, but the minimum diameter of existing side-emitting optical fiber is 0.75mm, and it is hard and brittle, and the optical fiber is easy to slip off the fabric, which is not suitable for weaving. In addition, the weaving methods of existing optical fiber weaving fabrics are mostly satin and plain, and the satin fabric has good light-guiding performance, but because the light-guiding principle of optical fiber is that light is totally reflected inside the fiber, the large area of ​​the fiber outside cannot realize light emission. If light emission is realized, the fiber must be bent before and after weaving to realize the transmission of faint light at the bending point, but the main light is still conducted inside the same optical fiber, and the light-guiding performance on the surface of the fiber fabric is not ideal, and the light is weak. At the same time, some interwoven structures such as satin fabrics have poor anti-friction ability and the fibers are easy to break. In order to solve the problems of end-luminous fiber light guiding only the two ends of the fiber are strong, the rest of the light is weak, the luminous fiber fabric has poor friction resistance, and the satin weaving method has low light guiding efficiency, etc., an adhesive layer is provided at the intersection of the fabric interweaving structure, which can not only strengthen the interweaving structure, but also realize the change of light path, transfer the light to different optical fibers, and increase the fabric surface transmission of the light path. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a flexible interwoven structure luminous fabric that changes the light path and a preparation method thereof. The core technology of the luminous fabric described in the present invention is to form a luminous contact strip, and connect the side luminous warp and the luminous contact strip with an adhesive point, and transmit the light of the side luminous optical fiber to the luminous contact strip at the adhesive point, thereby changing the light emitting direction of the end-face luminous optical fiber, so that its light outlet covers the surface of the fabric, rather than the two ends, thereby improving its luminous effect, making the surface of the luminous fabric more uniform, higher in brightness, and better in luminous effect and aesthetics. The luminous fabric provided by the present invention can realize the application of optical fibers in smart wearables, lighting, special textile fabrics, light energy transmission, decorative items, stage performances, safety warnings and other aspects.

[0005] The technical solution of the present invention is as follows:

[0006] A luminous fabric with a flexible interwoven structure for changing the light path, comprising warps, wefts, contact points and adhesive points; the warps comprise side-luminous warps and base warps; the wefts comprise luminous contact strips and base wefts; the contact points are points where the warps and wefts are interwoven; the side-luminous warps and base warps are arranged in sequence or in different component proportions; the luminous contact strips and base wefts are arranged in sequence or in different component proportions; the base wefts are interwoven with the warps; the luminous contact strips are prepared from end-luminous optical fibers, specifically by cutting the end-luminous optical fibers; during preparation, the end-luminous optical fibers are used as end-luminous wefts and interwoven with the warps in the form of a fabric structure with more floating threads (e.g., satin), the contact points where the wefts are on top and the warps are on the bottom are called floating points, the contact points where the warps are on top and the wefts are on the bottom are called sinking points, the end-luminous optical fibers are cut from the middle of the continuously arranged floating points to obtain the luminous contact strips; the adhesive points are obtained by bonding the warps and the luminous contact strips at the sinking points. Among them, the adhesive point where the side-emitting warp line is bonded to the emitting contact strip has the function of changing the light path.

[0007] Furthermore, the adhesive point is obtained by bonding the side-emitting warp line to the contact point of the luminous contact strip, and the contact point is a sinking point.

[0008] Furthermore, the continuous floating points are regarded as a floating line, and the number of floating points contained in each floating line is ≥1. The more floating points, the less light intensity dissipation and the higher the luminous brightness. However, the more floating points, the more unstable the fabric structure and the easier the fabric is to be damaged. Therefore, the preferred floating point number is 4, 6, 8, or 10.

[0009] Furthermore, the sinking point is the contact point between the side-emitting warp line and the end-emitting optical fiber.

[0010] Furthermore, the weft threads are distributed in the form of at least one row of base weft threads and at least one row of luminous touch strips; the material of the base weft threads includes but is not limited to nylon fibers, preferably nylon fibers, and other materials similar to nylon can also be used as the base weft threads of the present invention.

[0011] Furthermore, the warps are distributed in the form of at least one column of side-emitting warps and at least one column of base warps.

[0012] Furthermore, the interweaving methods of the base weft and warp include plain weave, satin weave and twill weave. The interweaving methods can be the above three methods, but are not limited to the above three methods. Other weaving forms that can achieve the same effect are also within the protection scope of the present invention.

[0013] Furthermore, the end-emitting weft and warp are preferably satin-woven, but not limited to the above method, and other weaving forms that can achieve the same effect are also within the protection scope of the present invention.

[0014] Furthermore, the material of the base warp includes but is not limited to nylon fiber, preferably nylon fiber, and other materials similar to nylon can also be used as the base warp of the present invention; the side-emitting warp includes a core material and a skin material; the material of the core material includes but is not limited to methyl methacrylate; the material of the skin material includes but is not limited to fluororesin, the core material and the skin material can also be replaced by other materials that can be used to prepare side-emitting optical fibers, and the present invention is not limited to this. The material of the core material is preferably methyl methacrylate, and the material of the skin material is preferably fluororesin.

[0015] Furthermore, the end-emitting optical fiber includes a core material and a skin material; the material of the core material includes but is not limited to polymethyl methacrylate, and the material of the skin material includes but is not limited to fluororesin. The core material and the skin material can also be replaced by other materials that can be used to prepare end-emitting optical fibers, and the present invention is not limited to this. The material of the core material is preferably polymethyl methacrylate, and the material of the skin material is preferably fluororesin.

[0016] Furthermore, the preparation method of the luminous touch strip is:

[0017] S1: Design the arrangement ratio of warp and weft, and the end-luminous weft is preferably woven in satin. The contact point where the weft is on top and the warp is on the bottom is called a floating point. At this time, the weft between the first and last floating points is a floating line. Set the number of floating points on each floating line so that the sinking point includes the contact point between the side-luminous warp and the end-luminous weft.

[0018] S2: Based on the designed warp and weft arrangement diagram, the warp and weft are set on the loom, and weaving begins. The heald frame is lifted, the side-luminous warp is opened, and the end-luminous weft is embedded in the opening formed by the side-luminous warp by beating-up. Weaving is started according to the fabric structure form containing floating threads. After weaving, the end-luminous weft is cut from the middle position of each floating thread to obtain several luminous touch strips.

[0019] In one embodiment of the present invention, all sink points are contact points between the side-emitting warp threads and the end-emitting weft threads.

[0020] Furthermore, the bonding is performed by welding using fluororesin solvent vapor.

[0021] Furthermore, the luminous fabric also includes a light-emitting component; the light-emitting component is arranged at the end of the side-emitting optical fiber and is further connected to an alternating current or a battery module to provide it with the required power supply.

[0022] Furthermore, the light-emitting components include light-emitting diodes and the like.

[0023] Furthermore, the fabric weave containing floats includes satin, twill or plain weave and their variation, combination or related complex weaves.

[0024] Another object of the present invention is to protect a method for preparing the luminous fabric, comprising the following steps:

[0025] S1: Design the floating point number, the arrangement ratio of the side-emitting warp and the base warp, and the arrangement ratio of the base weft and the end-emitting weft, so that the sinking point includes or is the contact point of the end-emitting weft and the side-emitting warp; arrange the side-emitting warp and the base warp on the loom according to the design;

[0026] S2: The heald frame is lifted, and the side luminous warp and the base warp form an opening according to the designed rule. By beating up, the end luminous warp and the base warp are sequentially embedded in the opening formed by the side luminous warp and the base warp;

[0027] S3: Repeat step S2 to complete weaving and obtain a preliminary luminous fabric;

[0028] S4: Cut the end luminous weft thread on the initial luminous fabric from the middle position of the floating point of each floating thread to form a luminous touch strip;

[0029] S5: Use fluororesin solvent vapor to steam weld the warp and the luminous contact strip at the sinking point (when the side-luminous warp and the luminous contact strip form a sinking point, the effect is better), form an adhesive point, set the light-emitting components at the end of the side-luminous warp to obtain a luminous fabric.

[0030] Further, in step S1, the base weft threads, base warp threads, and side luminous warp threads are all woven in the form of plain weave, flat weave, or twill weave;

[0031] Furthermore, in step S1, the base weft threads, base warp threads and side luminous warp threads are preferably woven in a plain weave form. At this time, the effect of preventing the warp and weft threads from slipping is optimal.

[0032] Furthermore, in step S1, the end-light-emitting weft yarn is preferably woven in a satin or other form.

[0033] Further, in step S1, the warp arrangement ratio, arrangement mode and weaving floating point number are determined before weaving, so that the contact points adjacent to the first and last floating points of each section or at least one section of floating lines are the interlacing points of the side-emitting warp lines and the weft lines.

[0034] Furthermore, in step S5, the light-emitting components include light-emitting diodes and the like.

[0035] Furthermore, the diameter of the light-emitting optical fiber selected by the present invention is about 0.75 mm, and the thickness of the leather material should not be too thick, which will increase the loss of light; nor should it be too thin, which will result in poor adhesive effect. Therefore, the thickness of the leather material should be as thin as possible while satisfying the adhesive effect.

[0036] Furthermore, the steam welding is to place the unglued fabric in a reaction vessel containing fluororesin solvent vapor. At this time, the side-emitting warp threads and the outer fiber layer forming the luminous touch strips will begin to swell because they are both fluororesin materials. Since the positions where the bonding points are formed will contact each other when no bonding occurs, coupled with the swelling or even dissolution of the leather material itself and the action of steam, welding is achieved.

[0037] The beneficial technical effects of the present invention are:

[0038] The present invention weaves end and side optical fibers with good light-conducting properties in a woven form, and then uses fluororesin solvent vapor to weld two adjacent fibers at the contact point, and adheres the warp yarn and the luminous contact strip to form a nearly unbounded contact structure, i.e., a bonding point, so that light can propagate in the combined fabric structure, thereby improving the brightness and luminous effect of the luminous fabric light.

[0039] The present invention forms a plain, satin or twill weave through the base weft and the base warp and the side luminous warp, increases the number of interlacing points, improves the compactness of the fabric, compensates for the looseness of the fabric after cutting the floating threads, and enhances the mechanical properties of the fabric such as wear resistance and stretchability. At the same time, the base weft is made of durable fibers such as nylon, which further improves the durability and mechanical properties of the luminous fabric.

[0040] The present invention constructs a luminous contact strip and connects the side-luminous optical fiber to the luminous contact strip with an adhesive point, and transmits the light of the side-luminous optical fiber to the luminous contact strip at the adhesive point, thereby changing the light emission direction of the end-face luminous optical fiber so that its light covers the surface of the fabric rather than the two ends, thereby improving its luminous effect, making the luminous fabric glow more evenly, with higher brightness, better luminous effect and aesthetics, and can realize the application of optical fibers in smart wearables, lighting, special textile fabrics, light energy transmission, decorative items, stage performances, safety warnings and other aspects.

[0041] The present invention breaks the traditional thinking of textile fabrics in fabric structure design, changes the luminous angle of the end-luminous fiber, and enhances the luminous effect by cutting the warp or weft yarn as a whole or partially, and covering the cut luminous end surface on the fabric surface. The area of ​​the end points and inflection points is increased, thereby improving the problems of difficult luminescence and dim luminescence of the fabric.

[0042] The preparation method of the present invention enhances the luminous effect, and the luminous fiber is implanted in the fabric body, so that the luminous characteristics of the fabric will not disappear with washing, and due to the addition of other yarns, the toughness, elasticity, certain mechanical strength and durability of the fabric are further enhanced. The process method of the present invention is novel, and the formation of the luminous fiber adhesive point makes it have higher tensile and compressive strength.

[0043] The luminous fabric prepared by the present invention is novel and has good luminous effect. It can be made into various types of clothing and props, which enhances the comfort and atmosphere of use. It can also be combined with smart electronic products and can also be used in furniture, industry, medical and other fields, bringing huge benefits to the relevant industrial chain.

[0055] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0056] The present invention provides a luminous fabric with a flexible interwoven structure that changes the direction of light propagation to improve the luminous effect, which has uniform luminescence, can improve luminous effect, can provide a new luminous fabric style, can improve the durability of the optical fiber luminous fabric, and is more convenient for customizing patterns.

[0057] The structure of the flexible interwoven structure luminous fabric for changing the light path of the present invention comprises: side luminous warp threads, luminous contact strips, adhesive points, and contact points; the intersection of the side luminous warp threads and the luminous contact strips is the adhesive point, which is welded by resin vapor.

[0058] The specific process of the resin steam welding is as follows: placing the fluororesin in a high-pressure reactor, setting the temperature to 220°C to 250°C, the pressure to 4.0MPa to 4.1MPa, reacting for 5min to 10min to produce steam. Then placing the fabric in the reactor filled with fluororesin steam for 20min to 40min, and welding is performed at the adhesive point where the luminous warp and the luminous contact strip intersect.

[0059] In one embodiment of the present invention, the material of the luminous contact strip is end-luminous optical fiber, which is used as end-luminous weft in weaving.

[0060] As an embodiment of the present invention, the end-light-emitting weft includes a core material and a skin material; the core material includes PMMA, and the skin material is fluororesin.

[0061] In one embodiment of the present invention, the preparation method of the luminous touch strip is as follows: the heald frame is lifted, the side luminous warp is opened, and the end luminous weft is embedded in the opening formed by the side luminous warp by beating the weft, the floating point number is set to be ≥6, and after the weaving is completed, the end luminous weft is cut from the middle position of the floating point to obtain the luminous touch strip.

[0062] In one embodiment of the present invention, the structure of the light-emitting fabric with a flexible interwoven structure that changes the light path further includes base warp threads and base weft threads.

[0063] In one embodiment of the present invention, the warp threads include base warp threads and side-lighting warp threads; and the weft threads include base weft threads and light-emitting contact strips.

[0064] As an embodiment, the arrangement ratio of the side-emitting warp threads to the base warp threads is 2:5.

[0065] As an embodiment, the arrangement ratio of the luminous touch strips to the base weft threads is 1:1.

[0066] As an embodiment, the raw material of the luminous touch strip is end-luminous weft, and during weaving, the arrangement ratio of the end-luminous weft to the base weft is 1:1; satin weaving is preferred in the weaving of the end-luminous weft, the floating point number is ≥6, the arrangement ratio of the side-luminous warp to the base warp is 2:5, and when the end-luminous weft is a non-floating point, it is in contact with the side-luminous warp to form an adhesive point.

[0067] Compared with common optical fiber woven fabrics, the structure of the present invention has two kinds of yarns on both the warp and the weft, the warp is the side luminous warp and the base warp, and the weft is the luminous contact strip and the base weft, which can reduce the tensile force of the luminous fabric during the weaving process and the stress during use, making the fabric more durable. The presence of the luminous contact strip makes the luminescence more uniform, the luminous effect better, and the appearance more beautiful.

[0068] In one embodiment of the present invention, the luminous contact strip is composed of an end-emitting optical fiber with a core material of PMMA and a skin material of fluororesin. The optical fiber has an external light source transmitted through the side-emitting warp. When passing through the adhesive point, the optical fiber transmits the light to the end-emitting contact strip, so that the end-emitting fiber can also achieve the luminous effect of the side-emitting fiber.

[0069] In one embodiment of the present invention, the side-emitting warp includes but is not limited to a side-emitting optical fiber with a core material of PMMA and a skin material of fluororesin, and the end-emitting weft (i.e., the luminous contact strip before treatment) includes but is not limited to an end-emitting optical fiber with a core material of PMMA and a skin material of fluororesin. Polymer optical fiber has good flexibility, is slender, soft, light, has a large diameter, is easy to couple, is non-conductive, and can conduct light sources.

[0070] In one embodiment of the present invention, the optical fiber at the sinking point is welded by a fluororesin solvent to form an adhesive point. The specific method of fluororesin solvent welding is as follows: the fabric is placed in a high-pressure reactor containing a fluororesin solvent, and the skin material of the side-emitting warp and the end-emitting warp is swollen or dissolved. The core material will not change much due to its high melting point. After the skin material swells or dissolves, it contacts each other at the sinking point, and the presence of steam fills (fills) the tiny pores at the contact point, so that the skin material at the sinking point is glued together to form an adhesive point.

[0071] In one embodiment of the present invention, the base weft and base warp are selected to include but are not limited to nylon, which has the properties of being strong and wear-resistant, having low density, light fabric, good elasticity, and resistant to fatigue damage. It can not only make up for the disadvantage of optical fiber being not wear-resistant, but also play the role of consolidating the fabric.

[0072] In one embodiment of the present invention, the fabric is presented in the form of a woven fabric, and the warp and weft yarns are composed of two systems. The warp yarn includes a side-emitting warp and a base warp, and the arrangement ratio of the side-emitting warp to the base warp includes but is not limited to 2:5 (the present invention does not limit the arrangement ratio of the side-emitting warp to the base warp, but it must meet certain conditions: assuming that the arrangement ratio of the side-emitting warp to the base warp is a:b, then the floating point number is a+b-1). The end-emitting weft is cut from the middle of the floating line, and the sinking point of the end-emitting weft is the contact point with the side-emitting warp. The weft yarn uses the end-emitting weft and the base weft. The base weft is interwoven with the warp in a plain weave. After weaving two, the end-emitting weft is interwoven with the warp in a satin weave. The number of floating line tissue points is 6 (it can also be determined according to the situation. When the fabric is dense, the number of floating points can be appropriately increased. It is only necessary to ensure that the contact points after each last floating point of the end-emitting weft are all adhesive points, that is, the warp is a side-emitting warp). After weaving is completed, the floating thread is cut from the middle by machine or manual, and the base weft thread plays a consolidation role. Finally, a kind of glue is used to bond the contact point of the luminous contact strip and the side luminous warp thread to form a glue point.

[0073] The luminous fabric of the flexible interwoven structure prepared by the present invention emits light through the principle of optical fiber light transmission. The polymer optical fiber and ordinary yarn are woven into the fabric to form a luminous fabric. The light transmission principle of the present invention is as follows Figure 6 As shown. In the figure, 1 is the side-emitting warp, 2 is the emitting contact strip, 3 is the adhesive point, and 4 black arrows are partial conduction paths of light in the optical fiber. The incident direction of light is as shown in the figure. The light is transmitted to the adhesive point 3 through the side-emitting warp 1. The skin-core interface of the side-emitting warp used in the present invention has a certain degree of roughness, so the side-emitting effect can be achieved. Therefore, when the light is transmitted to the adhesive point 3, due to the certain roughness of the skin-core interface, the light is refracted here, and then enters the cortex, and then passes through the cortex material at the adhesive point, and is transmitted from the side-emitting warp to the inside of the emitting contact strip, refracted at the skin-core interface of the emitting contact strip, and enters the core layer of the emitting contact strip, and then total reflection occurs, and is transmitted to the end face of the emitting contact strip, realizing end face luminescence.

[0074] Since the polymer optical fiber itself does not emit light but can only conduct light, in actual use, it is necessary to connect light-emitting components such as light-emitting diodes (LEDs) as light sources to the polymer optical fiber, so as to transmit light to the side-emitting warp threads to make them emit light. At the same time, the adhesive points can be used to transmit the light of the side-emitting optical fiber to the end face of the luminous contact strip, so that the surface of the fabric can emit light better. Combined with the circuit design, the fabric can be illuminated with specific aesthetics. The circuit design is a series circuit formed by a battery, an LED and a switch, which bundles all the side-emitting warp threads and aligns the LED with the bundled warp threads to make them emit light.

[0089] The side-emitting warp and the end-emitting weft are welded at the contact point using fluororesin solvent vapor. Specifically, the fluororesin is placed in a high-pressure reactor, the temperature is set to 220°C, the pressure is set to 4.02MPa, and the reaction is carried out for 10 minutes to produce vapor. The fabric is then placed in a reactor filled with fluororesin vapor for 30 minutes to achieve welding.

[0090] During welding, a nearly unbounded contact structure, i.e., a bonding point, can be formed by bonding the weft-extending fibers to the contact point.

[0091] The fabric prepared in Example 1 was further shaped: first, it was cut into pieces according to the size of 120 mm × 120 mm, and the right-angle edges were chamfered with a chamfer radius of 10 mm. Then, the fabric was hemmed: the cut flexible interwoven structure luminous fabric was hemmed in the warp direction with a polyester-cotton blended plain weave fabric, and the hemming width was 10 mm.

[0092] When in use, the prepared fabric is irradiated with diode light along the warp direction. Test results show that both the side-luminous warp threads and the luminous contact strips can emit light, and the fabric emits light evenly with good luminous effect. Figure 7 This is a rendering of the flexible interwoven structure luminous fabric of the present invention applied to a shoe upper.

[0093] Example 2

[0094] The preparation process and method are the same as those described in Example 1, except that the arrangement ratio of the side-emitting warp threads to the base warp threads is 3:5, and the arrangement ratio of the base weft threads to the luminous contact strips is 3:3; and the floating point number is 7.

[0095] Example 3

[0096] The preparation process and method are the same as those described in Example 1, except that the arrangement ratio of the side-emitting warp threads to the base warp threads is 1:1, and the arrangement ratio of the base weft threads to the luminous contact strips is 1:1; and the floating point number is 1.

[0097] Example 4

[0098] The preparation process and method are the same as those described in Example 1, except that the arrangement ratio of the side-emitting warp threads to the base warp threads is 4:7, and the arrangement ratio of the base weft threads to the luminous contact strips is 4:4; and the floating point number is 10.

[0099] Example 5

[0100] The preparation process and method are the same as those described in Example 1, except that the arrangement ratio of the side-emitting warp threads to the base warp threads is 2:4, and the arrangement ratio of the base weft threads to the luminous contact strips is 2:2; and the floating point number is 5.

[0101] The present invention can obtain a luminous fabric with excellent mechanical properties and luminous effects by adjusting the arrangement ratio and floating point number of the warp and weft threads. The addition of luminous touch strips improves the luminous effect of the fabric, and the base warp and base weft threads ensure the mechanical properties of the fabric.

[0102] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
