DOUBLE-FACED WOVEN FABRIC
A double-faced woven fabric includes a first and a second weave unit interlocked to each other at a plurality of stitching points. The first weave unit includes a plurality of interlaced first warp and weft threads to define a first face, and the second weave unit includes a plurality of interlaced second warp and weft threads to define a second face, which is not coplanar with the first face. The stitching points are formed by crossing the first warp threads over predetermined second weft threads, so that the stitching points are always covered by float second warp threads adjacent to the stitching points. The double-faced woven fabric with the interlocked first and second weave units has largely increased fabric strength and can present different textures, colors or patterns on the first and the second face to thereby provide good applicability.
The present invention relates to a woven fabric that presents different textures, colors or patterns on two opposite faces thereof, and more particularly to a double-faced woven fabric that include a first weave unit and a second weave unit interlocked at a plurality of stitching points without showing defective color spots at the stitching points.
BACKGROUND OF THE INVENTIONWith the progress and development in different scientific and industrial fields, new and good weaving techniques are constantly introduced into the market. The textile industry has close relation with people's daily life and plays a very important role in supplying products in connection with clothing, housing and traffic means needed by most people. In brief, the textile industry is one of the most important sectors in the livelihood-related industries. Following the upgraded living quality in the modern society and people's strong demand for constantly improved textile products, various fabrics of different functions have been developed.
By “fabrics”, it means sheets of cloth that are formed by, for example, interlacing, weaving or knitting fibers or yarn and threads in predetermined manners. The currently available fabrics can be divided according to texture and processing principle into woven fabrics, knitted fabrics, non-woven fabrics, and fabrics with other structures. All these types of fabrics can serve as clothing fabric, furnishing fabric and industrial fabric according to their applications. The forming of these fabrics is generally referred to as the manufacture of fabric.
The conventional double-faced fabric requires additional processing procedures, which inevitably increases the manufacturing cost of the fabric. Further, the two pieces of cloth being bonded together to form the conventional double-faced fabric are subject to separation from each other after the double-faced fabric has been used and washed many times. Even with the conventional double-faced fabric formed by sewing two pieces of cloth together, the sewing thread 22 is subject to loosening or breaking to cause complete or partial separation of the two pieces of cloth from each other. In brief, the conventional double-faced fabric is formed by bonding or sewing together two pieces of cloth of different colors and textures, and has the disadvantages of high manufacturing cost and not durable for use.
SUMMARY OF THE INVENTIONA primary object of the present invention is to provide a double-faced woven fabric having upgraded fabric strength, attractive appearance and good applicability by interlacing warp threads and weft threads of different colors using general weaving materials and weaving machines to form two weave units interlocked via a plurality of stitching points formed between them, so that different colors and textures can be presented on two opposite faces of the woven fabric.
Another object of the present invention is to provide a double-faced woven fabric characterized by that all stitching points thereof are covered by float warp threads adjacent to the stitching points, so that both faces of the woven fabric present color integrity without any defects of different color spots at the stitching points.
To achieve the above and other objects, the double-faced woven fabric according to the present invention includes a first weave unit, a second weave unit, and a plurality of stitching points. The first weave unit includes a plurality of longitudinally spaced first warp threads and a plurality of transversely spaced first weft threads, which are interlaced to define a first face. The second weave unit includes a plurality of longitudinally spaced second warp threads and a plurality of transversely spaced second weft threads, which are interlaced to define a second face. The second face and the first face are not coplanar. The stitching points are formed by crossing the first warp threads of the first weave unit over predetermined second weft threads of the second weave unit, so that the first weave unit and the second weave unit are interlocked at the stitching points.
According to the present invention, at least one of two second warp threads that are adjacent to two lateral sides of each stitching point is a float warp, so that the first warp threads at the stitching points are covered by the float second warp threads adjacent thereto after water shrinkage of the produced double-faced woven fabric. In the present invention, all the float second warp threads for covering the first warp threads at the stitching points are located at the same lateral side of the stitching points, and the stitching points are spaced from one another by a predetermined number of warp threads or weft threads.
In a preferred embodiment of the present invention, the first face and the second face defined by the first weave unit and the second weave unit, respectively, are selected from the group consisting of a plain-weave face, a twill-weave face, a checkered face, a striped face, and a face showing any geometrical patterns.
The present invention is characterized by interlacing warp threads and weft threads of different colors using general weaving materials and weaving machines to form two weave units, which are not coplanar and are interlocked at a plurality of stitching points between them to thereby form a double-faced woven fabric. The double-faced woven fabric so formed has largely increased structural strength, and can present different colors, textures and patterns on the first and second faces, giving the woven fabric attractive appearance and good applicability.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein
The present invention will now be described with some preferred embodiments thereof and with reference to the accompanying drawings. For the purpose of easy to understand, elements that are the same in the preferred embodiments are denoted by the same reference numerals.
The present invention provides a double-faced woven fabric that presents different textures and colors at two opposite faces thereof. The double-faced woven fabric of the present invention is obtained mainly by weaving warp threads and weft threads of different colors, such that two weave units located in two different planes are mutually connected via a plurality of stitching points. The double-faced woven fabric of the present invention can be woven using general weaving materials and weaving machines without any particular restriction thereto.
Please refer to
The stitching points 50 are formed by crossing the first warp threads 31 of the first weave unit 30 over predetermined second weft threads 42 of the second weave unit 40, so that the first weave unit 30 and the second weave unit 40 are interlocked at the stitching points 50.
In the illustrated first preferred embodiment, 300 denier (d/f) warp and weft threads are used (denier is defined as “the mass of thread W per 9000 meters of thread length L”), and the warp and weft threads are woven at a density of 120×70 per inch. Both the warp threads and the weft threads include alternately spaced red and orange threads. As an assembled weave structure diagram shown at the top of
As shown, A1, A5, C3, C7, E1, ES, G3 and G7 are weave points with red warp floats, while B2, B6, D4, D8, F2, F6, H4 and H8 are weave points with orange warp floats. Regarding the orange warp threads at weave points B1, B3, B5, B7, D1, D3, D5, D7, F1, F3, F5, F7, H1, H3, H5 and H7, since B, D, F and H are threads in an upper second plane, warp threads B, D, F and H all are located over a lower first plane defined by the weft threads 1, 3, 5 and 7 to form raised weave points.
As can be seen from the exploded diagrams A1 to A3, the odd warp threads in red and the odd weft threads in red are located in the lower first plane and are interlaced to form a piece of red plain-weave cloth defining a lower face of the double-faced woven fabric. Similarly, as can be seen from the exploded diagrams B1 to B3, the even warp threads in orange and the even weft threads in orange are located in the upper second plane and are interlaced to form a piece of orange plain-weave cloth defining an upper face of the double-faced woven fabric.
In the present invention, the stitching points 50 are so designed that they can be covered by the weave at one lateral side thereof, so as to avoid forming defective color spots on the woven fabric at the stitching points 50. In the case of failing to cover the stitching points 50, orange stitching points would appear on the red plain-weave cloth and red stitching points would appear on the orange plain-weave cloth.

According to a preferred embodiment of the present invention, the stitching points 50 are spaced from one another by a predetermined number of warp threads or weft threads. As shown in
As can be seen from
From the above description, it can be found that, in the preferred embodiment as shown in
For example, in the case the first warp thread C interlaces with the second weft thread 2, the first warp thread G can be interlaced with the second weft threads 2 and 6 to form two stitching points; or alternatively, in the case the first warp thread C interlaces with the second weft thread 4, the first warp thread G can be interlaced with the second weft threads 4 and 8 to form two stitching points. Thus, it is ensured the first warp thread G at the two stitching points (G, 2; G, 6) or (G, 4; G, 8) can always be covered by the shrunk float second warp threads adjacent to the same lateral side of the stitching points, allowing the stitching points to invisibly locate between the lower face (i.e. the first weave unit) and the upper face (i.e. the second weave unit) of the double-faced woven fabric.
In the illustrated second preferred embodiment, 300 denier (d/f) warp and weft threads are used (denier is defined as “the mass of thread W per 9000 meters of thread length L”), and the warp and weft threads are woven at a density of 120×70 per inch. The warp threads include red threads and light khaki threads, and the weft threads include only red threads. As an assembled weave structure diagram shown at the top of
As can be seen from the diagrams C1 to C3, the even warp threads in red and the odd weft threads in red are interlaced to form a piece of red plain-weave cloth. Similarly, as can be seen from the diagrams D1 to D3, the even warp threads in light khaki and red and the even weft threads in red are interlaced to form a piece of twill-weave cloth showing red and light khaki colors.
As shown in
According to the above two embodiments of the present invention, the first face defined by the first weave unit 30 and the second face defined by the second weave unit 40 can be differently designed according to the required appearances, textures and colors. For example, the first face and the second face can respectively be a plain-weave face, a twill weave face, a checkered face or a striped face for forming two opposite faces of the double-faced woven fabric of the present invention. It is understood the textures and colors mentioned in the above-described embodiments are only illustrative to enable easy explanation of the present invention and not intended to limit the appearances and shapes of the first and second faces in any way. In other words, the first face and the second face may also show any other geometrical patterns and colors.
In brief, according to the present invention, warp threads and weft threads of different colors are interlaced to produce a double-faced woven fabric showing different colors and textures on two opposite faces thereof. The double-faced woven fabric of the present invention can be woven with general weaving materials and weaving machines without any particular restriction thereto, and includes two weave units that define two different faces of the woven fabric and are connected together via a plurality of stitching points between them. The double-faced woven fabric so formed has largely upgraded structural strength, attractive appearance and good applicability. Further, the double-faced woven fabric of the present invention is characterized by that all the stitching points are covered by the float second warp threads adjacent to the stitching points, so that both faces of the woven fabric present color integrity without showing any defects of different color spots at the stitching points.
The present invention has been described with some preferred embodiments thereof and it is understood that many changes and modifications in the described embodiments can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
