Definitions
- the instant disclosure relates to a luminous fabric; more particularly, to a luminous fabric having both passive and active luminating capabilities.
- Luminous fabric for lighting, decorations, and warning system applications can generally be divided into two categories.
- the first category involves passive illumination, such as light-reflecting devices that require no electrical power. By being able to reflect incoming light, these light-reflecting devices increase night time visibility.
- passive luminating devices are plastic reflective strips, reflectors, etc. However, they are usually made of hard and rigid materials. Moreover, these passive devices cannot illuminate without an external light source, because there is no light to reflect.
- the second category involves active illumination, such as devices that incorporate fluorescent compounds or light bulbs, etc. These active luminous devices usually appear shiny and depend less on ambient conditions. However, they are usually more complex, bulky, and expensive. These negative attributes inevitably limit their practical applications in draperies for decoration.
- optical fibers are specially processed to enable side emission of light along their length as light source is provided at one end thereof. The light would travel throughout the lengths of the fibers and be emitted through the lateral surface. This type of optical fibers is known as “side emitting fibers”.

Abstract
A luminous fabric includes a plurality of first light-reflecting fiber units, a plurality of light-guiding fiber units, and a plurality of light-accumulating fiber units. The first light-reflecting fiber units are directed toward a first direction and spaced apart in intervals. The light-guiding fiber units are directed toward a second direction and spaced apart in intervals. Each light-guiding fiber unit has a lateral light-guiding portion. Some light-accumulating fiber units are drawn through the first light-reflecting fiber units, and some other light-accumulating fiber units are drawn through the light-guiding fiber units. Thereby, the luminous fabric can provide passive illumination when a light source is provided, and provide active illumination in dark settings. The light reflected by the luminous fabric is concentrated and uniformly distributed on one side thereof.
Description
- This Application is being filed as a Continuation-in-Part of patent application Ser. #12/289,411, filed 28 Oct. 2008, currently pending.
- 1. Field of the Invention
- The instant disclosure relates to a luminous fabric; more particularly, to a luminous fabric having both passive and active luminating capabilities.
- 2. Description of Related Art
- Luminous fabric for lighting, decorations, and warning system applications can generally be divided into two categories.
- The first category involves passive illumination, such as light-reflecting devices that require no electrical power. By being able to reflect incoming light, these light-reflecting devices increase night time visibility. Some examples of passive luminating devices are plastic reflective strips, reflectors, etc. However, they are usually made of hard and rigid materials. Moreover, these passive devices cannot illuminate without an external light source, because there is no light to reflect.
- The second category involves active illumination, such as devices that incorporate fluorescent compounds or light bulbs, etc. These active luminous devices usually appear shiny and depend less on ambient conditions. However, they are usually more complex, bulky, and expensive. These negative attributes inevitably limit their practical applications in draperies for decoration.
- Most conventional light emitting fabric only uses optical fibers. These optical fibers are specially processed to enable side emission of light along their length as light source is provided at one end thereof. The light would travel throughout the lengths of the fibers and be emitted through the lateral surface. This type of optical fibers is known as “side emitting fibers”.
- However, the existing light emitting fabric can only provide passive illumination. The inability of the fiber optics fabric to provide active illumination means that there is still room for improvement. In addition, the existing optical fibers in conventional luminous fabric lack adequate mechanical flexibility (softness) and the illumination effect is often not uniform, and therefore cannot provide satisfactory illuminating effect for luminous clothing and decorations.
- To address the above issues, the inventor strives via industrial experience and academic research to present the instant disclosure, which can effectively improve the limitations described above.
- To resolve the above limitations, the instant disclosure provides a light-accumulating luminous fabric that processes both passive and active illumination characteristics, can concentrate the emitted light on the same side thereof and provide uniform illumination, and is flexible, lightweight, and portable.
- The luminous fabric in accordance with the instant disclosure comprises a plurality of first light-reflecting fiber units, a plurality of light-guiding fiber units, and a plurality of light-accumulating fiber units. The first light-reflecting fiber units are arranged substantially parallel to each other along a first direction with intervals there-between. Likewise, the light-guiding fiber units are arranged substantially parallel to each other along a second direction. Each light-guiding fiber unit has at least one side emitting portion. A portion of the light-accumulating fiber units are interwoven with the first light-reflecting fiber units, while at least a portion of the light-accumulating fiber units are interwoven with the light-guiding fiber units.
- The luminous fabric in accordance with the instant disclosure has the following advantages. The light-accumulating fiber units can provide active illumination in dark settings. Meanwhile, passive illumination is achieved by the light reflecting characteristic of the first light-reflecting fiber units in cooperation with the light-guiding fiber units. In particular, the reflected light is concentrated on one side of the fabric in providing uniform illumination. Moreover, the first light-reflecting fiber units allow the fabric to be soft, lightweight, and portable. The above attributes make the fabric a favorable choice for luminous clothing and decorations.
- In order to further appreciate the characteristics and technical contents of the instant disclosure, references are hereunder made to the detailed descriptions and appended drawings in connection with the instant disclosure. However, the appended drawings are merely shown for exemplary purposes, rather than being used to restrict the scope of the instant disclosure.

FIG. 1 . The instant disclosure provides aluminous fabric 1, which comprises a plurality of first light-reflectingfiber units 11, a plurality of light-guidingfiber units 12, and a plurality of light-accumulatingfiber units 13. The first light-reflectingfiber units 11 are spaced in intervals along a first direction. The light-guidingfiber units 12 are spaced in intervals along a second direction. Some light-accumulatingfiber units 13 are drawn through the first light-reflectingfiber units 11, while other light-accumulatingfiber units 13 are drawn through the light-guidingfiber units 12. Each of the light-guidingfiber units 12 has at least one lateral light-guiding portion (not shown). Through the use of the first light-reflectingfiber units 11, the light-guidingfiber units 12, and the light-accumulatingfiber units 13, theluminous fabric 1 of the instant disclosure possesses passive/active illumination and light reflecting characteristic. For example, the light-accumulatingfiber units 13 can provide active illumination in dark settings. Meanwhile, passive illumination can be achieved by the light reflecting characteristic of the first light-reflectingfiber units 11 in cooperation with the light-guidingfiber units 12. In particular, the reflected light can be concentrated on one side of theluminous fabric 1 in providing uniform illumination. Moreover, the first light-reflectingfiber units 11 allow theluminous fabric 1 to be soft, lightweight, and portable. The above attributes make the luminous fabric 1 a favorable choice for luminous clothing and decorations. - Please refer to
FIGS. 1 and 2 , which show a plan view of theluminous fabric 1 for a first embodiment of the instant disclosure and a cross-sectional view thereof taken along a cutting-plane A-A, respectively. As shown inFIG. 1 , the first light-reflectingfiber units 11 directed along the first direction, or the lengthwise direction, are warp threads. The light-guidingfiber units 12 directed along the second direction, or the crosswise direction, are weft threads. Please note, the running directions of the light-reflectingfiber units 11 and the light-guidingfiber units 12 in the figure are for illustration and explaining purposes only. Some light-accumulatingfiber units 13 are drawn through the first light-reflectingfiber units 11, while other light-accumulatingfiber units 13 are drawn through the light-guidingfiber units 12. The light-guidingfiber units 12 are interwoven with some first light-reflectingfiber units 11. - The first light-reflecting
fiber units 11 may be single or double-sided light-reflecting threads made of polyester or polyvinyl chloride (PVC). Cone-shaped micro structures can further be formed continuously on each light-reflecting thread. When light is projected onto those micro structures, the light reflection intensity of each thread is enhanced. The cross-sections of the first light-reflectingfiber units 11 can be polygonal. Based on the CNS-7773 standard administered by the Chinese National Standards (CNS), the glossiness of the first light-reflectingfiber units 11 is evaluated. For example, the level of glossiness is classified into a scale of grade one to ten by CNS-7773. If the gloss value falls between grade one and three, the object is considered to be not light reflective. If the gloss value is somewhere between grade three and ten, the object is deemed to possess light-reflecting ability. The first light-reflectingfiber units 11 can have any gloss value between grade three and grade ten. Along with different shapes of cross-section, different types of light-reflectingfiber units 11 can be used for theluminous fabric 1. For this embodiment, the gloss value of the first light-reflectingfiber units 11 is preferably to be at grade six. - Each light-guiding
fiber unit 12 may comprise 1˜7 light-guiding fiber(s) arranged in a bundle, with 3˜5 being the preferable number. Each light-guidingfiber unit 12 can have at least one lateral light-guiding portion (not shown). A fluorocarbon layer is coated on the lateral light-guiding portion. Small scratches are then formed on the side emitting portion. When one end of each light-guidingfiber unit 12 receives light from an external light source (not shown), the light would travel throughout the lengths of the light-guidingfiber unit 12 and emit through the small scratches. Thus, the light-guidingfiber units 12 are illuminated. - The light-accumulating
fiber units 13 can be made of composite light-accumulating fibers. For example, light-accumulating materials can be mixed with polypropylene (PP), polyethylene (PE), polyolefin resin, or polyester resin. By mixing, melting, extruding, quenching, elongating, and spinning, light-accumulating threads can be produced. Some examples of the light-accumulating threads are aluminate yarns, metal sulfides yarns, phosphorescent yarns, luminous yarns, etc. In particular, the yarns fabricated of metal sulfides can be achieved by mixing zinc sulfide with polypropylene. Meanwhile, the luminous yarn can be produced by mixing a homogeneous or heterogeneous metal oxide (e.g. strontium oxide and/or aluminum oxide) with europium (Eu) and/or dysprosium (Dy) rare earth element. Then, the mixture is added to the polyolefin or polyester resin to obtain the final product. Notably, the light-accumulatingfiber units 13 can first absorb light, whether from an artificial light source or natural light (ultraviolet light), and emit light afterwards. The emitted light is often referred to as the afterglow. Even after the light source is removed, the light-accumulatingfiber units 13 can maintain its illumination for a period of time, known as the “emitting time”. Moreover, the thickness of each light-accumulatingfiber unit 13 is usually less than 40 μm, giving a soft feel. The soft feeling renders the light-accumulatingfiber units 13 a favorable choice for embroidery and other clothing applications. The cross-section of each light-accumulatingfiber unit 13 can be circular, triangular, hollowed, etc. The denier of these light-accumulatingfiber units 13 is not restricted either. Along with excellent flexibility of the light-accumulatingfiber units 13, theluminous fabric 1 is an ideal choice for luminous clothing and decorations to be used in dark conditions or areas that are not well-lit. - The
luminous fabric 1 of the instant disclosure has between 50 to 210 threads per square inch. - Please refer to
FIG. 2 , which shows a cross-sectional view of theluminous fabric 1 inFIG. 1 taken along a cutting plane A-A. The circles shown in the figure represent the cross-sections 12 a of the light-guidingfiber units 12 or the cross-sections 13 a of the light-accumulatingfiber units 13. In other words, the light-guidingfiber units 12 or the light-accumulatingfiber units 13 are circular threads. The interweaving line that is adjacent to the circles is one of the first light-reflectingfiber units 11. For explaining purpose, the portion where light-guidingfiber units 12 are not interwoven with the first light-reflectingfiber unit 11 is denoted as a first region R1, while the interwoven region is defined as a second region R2. The artificial light emitted by the lateral light-guiding portion (not shown) of each light-guidingfiber unit 12 is denoted as a first light L1. The incoming light (e.g. sunlight) that is not emitted by the light-guidingfiber units 12 is denoted as a second light L2. As illustrated inFIG. 2 , the first light L1 and the second light L2 are reflected by the first light-reflectingfiber unit 11 over the first region R1 and the second region R2. In other words, the first light-reflectingfiber units 11 can reflect both artificial and natural light. Through the light reflecting characteristic of the first light-reflectingfiber units 11, the first light L1 and the second light L2 are reflected from the same side of theluminous fabric 1. Thus, the reflected light is concentrated on one side of theluminous fabric 1 and uniform illumination is accomplished. The first light-reflectingfiber units 11 provide passive illumination for theluminous fabric 1 of the instant disclosure. - As already set forth in
FIG. 1 , the light-accumulatingfiber units 13 interweave with the light-guidingfiber units 12 or the first light-reflectingfiber units 11. The light-accumulatingfiber units 13 can first accumulate light from the ambient light source, the first light L1, or the second light L2. Then, the light-accumulatingfiber units 13 can stay luminous for a period of time. Therefore, the light-accumulatingfiber units 13 provide active illumination for theluminous fabric 1 of the instant disclosure. - In summary, the
luminous fabric 1 of the instant disclosure possesses passive/active illumination and light reflecting characteristic. Therefore, theluminous fabric 1 can be used in many applications. For example, during daylight, the first light-reflectingfiber units 11 can directly reflect the natural light from the ambient or reflect the artificial light emitted by the light-guidingfiber units 12. Concurrently, the light-accumulatingfiber units 13 can absorb the natural or artificial light to produce afterglow. In this scenario, the first light-reflectingfiber units 11 play the primary role for illumination, while the light-accumulatingfiber units 13 play a more minor role. At night time, the first light-reflectingfiber units 11 can reflect the artificial light off the light-guidingfiber units 12, while the light-accumulatingfiber units 13 provide afterglow. For this second scenario, both the first light-reflectingfiber units 11 and the light-accumulatingfiber units 13 play major roles for illumination. Please note, the above discussed scenarios are only presented for explaining purposes and are not intended to restrict the scope of the instant disclosure. Theluminous fabric 1 of the instant disclosure can be used with any light source to produce different illuminating conditions. - Please refer to
FIGS. 3 and 4 .FIG. 3 is a plan view of theluminous fabric 1 for a second embodiment of the instant disclosure.FIG. 4 is a cross-sectional view thereof taken along a cutting-plane B-B. In the second embodiment, theluminous fabric 1 further includes a plurality of second light-reflectingfiber units 14. The second light-reflectingfiber units 14 are directed toward the second direction as weft threads. Each of the second light-reflectingfiber units 14 is arranged in among with the light-guidingfiber units 12. The second light-reflectingfiber units 14 are interwoven with the first light-reflectingfiber units 11. Notably, the gloss values of the first light-reflectingfiber units 11 and the second light-reflectingfiber units 14 are between three and ten. The use of first light-reflectingfiber units 11 and the second light-reflectingfiber units 14 having different gloss values and cross-sectional shapes can produce various illuminating conditions for theluminous fabric 1. Like the first embodiment, theluminous fabric 1 of this embodiment also has 50 to 210 threads per square inch. - Please refer to
FIG. 4 . The circles shown in the figure represent the cross-sections 12 a of the light-guidingfiber units 12 or the cross-sections 13 a of the light-accumulatingfiber units 13. In other words, the light-guidingfiber units 12 or the light-accumulatingfiber units 13 are circular threads. The triangles represent the cross-sections 14 a of the second light-reflectingfiber units 14. In other words, the second light-reflectingfiber units 14 are substantially triangular threads. The interweaving line that is adjacent to the circles and triangles is the first light-reflectingfiber unit 11. Notably, the cross-sections of the first light-reflectingfiber units 11 and the second light-reflectingfiber units 14 are substantially polygonal. The region where the light-guidingfiber units 12, the light-accumulatingfiber units 13, and the second light-reflectingfiber units 14 do not interweave with the first light-reflectingfiber unit 11 is defined as region 3, or R3. Meanwhile, the region where the second light-reflectingfiber units 14 interweave with the first light-reflectingfiber units 11 is defined as region 4, or R4. The structural descriptions of the light-guidingfiber units 12 and its connection to the light source are the same as previous embodiment, therefore are not repeated herein. The first light L1 and the second light L2 are reflected by the first light-reflectingfiber units 11 and the second light-reflectingfiber units 14 of regions 3 and 4. The first light L1 and the second light L2 are reflected from the same side of theluminous fabric 1. Thus, the reflected light is concentrated on one side of theluminous fabric 1 and uniform illumination is accomplished. The numbers of the light-guidingfiber units 12 versus the second light-reflectingfiber units 14 are between the ratios of 20:0 to 1:7. Please note, the ratio of 20:0 means all weft threads are light-guidingfiber units 12. Preferably, the numbers of the light-guidingfiber units 12 versus the second light-reflectingfiber units 14 are between the ratios of 20:0 to 1:5. - For the instant embodiment, the numbers of the light-guiding
fiber units 12, the light-accumulatingfiber units 13, and the second light-reflectingfiber units 14 are defined by the ratio of 1:1:2. In other words, two second light-reflectingfiber units 14 are inserted between one light-guidingfiber unit 12 and one light-accumulatingfiber unit 13. By varying the numbers of the light-guidingfiber units 12, the light-accumulatingfiber units 13, and the second light-accumulatingfiber units 14, different types ofluminous fabric 1 can be foamed for the instant disclosure. - The following descriptions relate to a third embodiment of the instant disclosure. In comparing to the second embodiment, the third embodiment further comprises at least one
polymer film 15. Please refer toFIG. 5 , which shows a cross-sectional view of theluminous fabric 1 for the third embodiment of the instant disclosure. One side or opposite sides of theluminous fabric 1 is laminated with thepolymer film 15. Thepolymer film 15 has a plurality of pores (not shown) formed thereon. The pores or any other type of water diffusing structure formed on thepolymer film 15 allow theluminous fabric 1 to possess water permeability. Thepolymer film 15 can be made of polyamino ethyl formate, polyester, polyether, polyamide, polyacrylate, copolyether, or copolyetheramide. For example, thepolymer film 15 having a plurality of micro pores formed thereon can be fabricated of polytetrafluoroethylene (PTFE), or better known as Teflon. In particular, an expanded polytetrafluoroethylene, or ePTFE, can be used. ePTFE is more commonly known by the brand name Gore-Tex, which is a registered trademark of W. L. Gore & Associates in Elkton, Md. in USA. - The descriptions below relate to a fourth embodiment of the instant disclosure. In comparing to the second embodiment, the
luminous fabric 1 of the fourth embodiment further comprises a plurality ofelectrical conducting units 16. Please refer toFIGS. 6 and 7 .FIG. 6 is a plan-view of thefabric 1 for the fourth embodiment of the instant disclosure.FIG. 7 is a cross-sectional view of theluminous fabric 1 inFIG. 6 taken along a cutting-plane C-C. As shown inFIG. 6 , someelectrical conducting units 16 are drawn through the first light-reflectingfiber units 11. Meanwhile, some otherelectrical conducting units 16 are interwoven/mixed with the light-guidingfiber units 12. Eachelectrical conducting unit 16 is formed by interweaving aninsulated thread 161 with an electricalresistance heating wire 162. Like previous embodiments, theluminous fabric 1 has 50 to 210 threads per square inch. Theelectrical conducting units 16 are lightweight, mechanically flexible, have excellent tensile strength, and are waterproof. The above characteristics allow theluminous fabric 1 to have a broad range of applications. Theluminous fabric 1 may be used for hiking apparels, protective gears, women's apparels (for menstrual cycle), thermally insulated baby bottles, hiking boots, medicines (heating pads), soft heaters, and can even be used on rooftops for melting ice/snow. - Furthermore, the heating capacity of the
electrical conducting units 16 depends on several contributing factors, which can be adjusted during the fabrication process of theluminous fabric 1. The contributing factors include: the total number ofelectrical conducting units 16 for theluminous fabric 1; the twisting angles of the electricalresistance heating wires 162; the number of electricalresistance heating wires 162 for eachelectrical conducting unit 16; the wire gauge and material of the electricalresistance heating wires 162; and the interweaving pattern of theelectrical conducting units 16 for theluminous fabric 1. - The
luminous fabric 1 of the instant disclosure has several advantages. Namely, the light-accumulatingfiber units 13 can provide active illumination in areas that are not well-lit. The light reflecting characteristics of the first and second light-reflectingfiber units fiber units 12 and incoming natural light. The reflected light is concentrated and uniformly distributed on one side of theluminous fabric 1. Based on numerous trials and experiments, the light reflecting ability and active illumination of theluminous fabric 1 are most effective when the numbers of the light-guidingfiber units 12 and second light-reflectingfiber units 14 fall between the ratios of 20:0 to 1:5. Meanwhile, the addition of the first and second light-reflectingfiber units luminous fabric 1. Thereby, theluminous fabric 1 can be easily processed and is lightweight. Theluminous fabric 1 has enhanced portability and is very suitable in using for luminous apparel and decorations. The presence of thepolymer film 15 allows theluminous fabric 1 to be waterproof and being water permeable. Moreover, theelectrical conducting units 16 enable theluminous fabric 1 to have thermal management ability. - The descriptions illustrated supra set forth simply the preferred embodiments of the instant disclosure; however, the characteristics of the instant disclosure are by no means restricted thereto.
