Title of Invention: A carpet with the ability to change color and design and its weaving method

Technical Field

[0001 ] The invention relates to carpet viewing and specifically discloses a multidesign carpet weaving method for any type of carpet.

Background Art

[0002] In the knotting step of carpet weaving, the weaver starts by knotting the yarn around pairs of warp threads to create the desired pattern. To create a knot, the weaver takes a strand of yarn and passes it over one warp thread, then under the next warp thread. The yarn is then brought back to the surface between the two warp threads and pulled tightly to form a loop. The ends of the yarn are then cut, leaving a tufted pile on the surface of the carpet.

[0003] The weaver repeats this knotting process row by row, following the design pattern. Depending on the complexity of the design, this can be a meticulous and time-consuming process. The weaver needs to pay close attention to detail to ensure that each knot is placed correctly and that the pattern remains consistent throughout the carpet.

[0004] Once the knots are tied, the weaving process begins. The weaver takes the weft threads, which are horizontal threads, and passes them through the warp threads, which are vertical threads. This interlacing of weft and warp creates the structure and strength of the carpet.

[0005] Throughout the weaving process, the weaver may also make adjustments to the pile height to create different textures or patterns. This can be done by using different knotting techniques or varying the tension of the yarn.

[0006] Overall, both the knotting and weaving steps require precision, patience, and skill. The weaver must have a deep understanding of the design and technique to bring out the intricate details and achieve a high-quality finished product.

[0007] Some patents address the new method of carpet weaving, for example:

[0008] CN. Pat. NO. entitled "Concave-convex carpet weaving method" discloses a method for weaving concave-convex carpets, specifically hand-knotted carpets. i This method involves using fine and coarse weft threads that pass through each warp thread in a specific sequence. Different weaving techniques are employed for the flower shape and floor parts of the carpet. When weaving the flower shape and floor parts, a knot is made using wool yarn between the previous thin weft and the following coarse weft.

Summary of Invention

[0009] The method involves changing the distance of the warps, changing the knot and its position on the warp, and changing the dyeing of the fiber. The carpet is tufted with a space between the tufts, and a knot is created on each strand. Two different knot models, the vertical knot and the tear knot, are used to enhance texture.

[0010] The vertical knot is executed by positioning the fiber substance in a U-shaped and horizontal manner behind the wrap. The hook is inserted from the back into the loop of the thread, and the two ends of the thread are passed through the loop from the front of the wrap, forming a knot. The fiber is then rotated 180 degrees within that specific section to reinforce the knot.

[0011] The tear knot is formed by elongating the thread into a teardrop shape, with a ring part at the top and a long tail at the end. The end of the tail is securely attached using an adhesive material as a glue. The tear loop is positioned horizontally, with the ring part located on the right side and positioned behind the loop. The end of the tail is passed over the loop and inserted into the loop section, and then gently pulled to secure it at the head of the knot.

[0012] By weaving these knots alternately from the back and the front, the number of final designs on each surface of the carpet is doubled. This means there will be two designs on each surface of the carpet and four different designs in each carpet board. The position of the threads is taken into consideration to create texture in this method.

[0013] To weave the knots on the carpets, the yarn is placed behind the carpet with the ring part on the right side and the tail on the left. The tail is brought over the carpet and passed through the loop head, and then slightly pulled to tighten the knot. The weaver can start weaving from the carpet first and weave the face knots on the face warps, then move to the back of the carpet and weave the knots of the warp below. After weaving a row on all the warps, the thick weft is passed, and then the thin weft between the warps.

[0014] With this method, the knots are in front of the carpet and maintain their rotating state on the back of the carpet. Each design is placed on the same side of the knot, allowing for intricate and complex patterns to be woven into the carpet. This technique can be used in both machine-woven and handwoven carpets to create unique and creative designs.

Technical Problem

[0015] In the ordinary and usual carpets, there is only one design with a unique or fixed color scheme, and if the design and color become boring over time, or the design and color of the carpet are not compatible with the new decoration, the consumer has to is to buy a new carpet with a new design and color, and this imposes a lot of cost on the person. Most importantly, raw materials, financial costs, and a lot of time are spent to weave a carpet, and if the weaver wants to weave two or three carpets, these costs will increase by two or three times, while with the methods disclosed in the present document, the weaver can tuft or make two or three designs at the same time on each surface of the carpet, and in this way, time and costs will be reduced, and there is no need to buy a new carpet. Also, the new color and dotting method presented in this invention increases the weaving speed.

Advantageous Effects of Invention

[0016] With this method presented in this invention, the weaving speed increases more than twice and the cost of raw materials is reduced to one-half to one-third (depending on the number of designs to be woven on one surface). Because the weaver only weaves one carpet, but with each knot tied on the chela, two or more designs are woven at the same time due to the color property of the creams and the different types of texture. And since the horizontal and vertical color and dot method can accommodate more than one design at the same time on a grid paper, it doubles the speed of reading colors and textures. It saves time and money.

Description of Embodiments

[0032] The solution can be done in two ways:

[0033] The first method: by changing the distance of the warps, changing the knot and its position on the warp, and changing the dyeing of the fiber (wool thread): In this method, the carpet can be tufted like the previous methods (fixed or rotating), but with the difference that there must be a space between the tufts (this space varies depending on the thickness of the tufts). In this method, a fiber substance is grasped by the user's hands and securely fastened onto the initial single strand. This procedure is subsequently replicated for the remaining strands, thereby creating a knot on each strand. The invention further encompasses the use of two distinct knot models for enhancing texture, namely: 1 ) Vertical knot and 2)Tear shape knot.

[0034] To execute the vertical knot, the fiber substance is positioned in a U-shaped and horizontal manner behind the wrap. Next, a hook(3) is inserted from the back into the loop of the thread. From the front of the wrap, the two ends of the thread are passed through the loop with the aid of the hook(3), ultimately forming a knot around the wrap (As shown in Fig. 1 ). To reinforce the knot, the fiber is then brought to the loop and rotated 180 degrees within that specific section.

Subsequently, the two ends of the thread are guided beneath the loop and drawn out from the center of the loop, resulting in a stronger knot (As shown in Fig. 2).

[0035] Tear knot: The tear knot is formed by elongating the thread into a teardrop shape, with a ring part(5) at the top and a long tail at the end, which appears as a pile on the surface of the carpet. The end of the tail is securely attached using an adhesive material as a glue. To initiate the weaving process for this knot, the tear loop is positioned horizontally, with the ring part located on the right side and positioned behind the loop. Using either a hand or a hook(3), the end of the tail is passed over the loop and inserted into the loop section. The tail is then gently pulled to ensure it is firmly secured at the head of the knot as shown in Fig. 3.

[0036] After tying the knots on the threads, one row of thick(7) and one row of thin weft(8) is woven. This method of weaving allows the knot to move freely on the skein, in both left and right directions.

[0037] Now, if these knots are woven as one in between (one from the back and the other from the front), the number of final designs on each surface of the carpet will be doubled, so that there will be two designs on each surface of the carpet and four different designs in each carpet board. For the texture in this way, the position of the threads is taken into consideration. Since the carpet threads are one in between, the first knot is tied (woven) from the back of the carpet on the lower carpet, and the second knot is woven from the surface of the carpet on the upper carpet. As shown in Fig. 6, to weave the knot on the carpets, first, the yarn is placed behind the carpet so that the ring part is on the right side and the tail of knot is on the left. Then, the tail is brought over the carpet passed through the loop head, and pulled slightly to tighten the knot. For ease of weaving, the weaver can start weaving from the carpet first and weave the face knots on the face warps (that is, leave the knots that should be woven on the lower warp unwoven), then move to the back to the carpet and weave the knots of the warp below until finally a row of weaving is done on all the warps. Now, the thick weft(7) is passed and then the thin weft(8) between the warps(1 ) (Fig. 7). With this method, the knots are also in front of the carpet and on the back of the carpet, it maintains its rotating state (Fig. 8) and each design is placed on the same side of the knot or nap direction (Fig. 9).

[0038] It should be noted that, for the desired texture, the use of a fiber (yarn) with two colors, one on the top and one on the bottom of each yarn, is necessary. This requirement means that each knot woven on each warp will contain two colors. In traditional carpets, the fiber used for pile texture is typically a single color, with occasional integration of two colors. However, by evenly applying the colors on both sides of the fiber, both colors can be utilized to create a design on the surface of the carpet. To dye the fibers, a coloring tool(13) for example a roller dipped in paint can be employed. The yarn is then passed between two colored rollers, each immersed in a different color. This process ensures that both sides of the yarn are dyed, resulting in each side having a distinct color, as depicted in Fig. 10

[0039] The second method involves changing the colors of the fibers to achieve layered designs on the knot's surface. In traditional carpets, each knot could only create a specific design, limiting the options for design and color. To overcome this limitation, the fiber is dyed with multiple colors, with each color occupying a different space on the fiber's surface based on the desired design. For example, if a five-centimeter pile thread is considered, the first three threads may be one color, followed by three threads of another color, and then three threads of a different color. The next one and a half centimeters may have a different color. This pattern is repeated in a mirrored image until the end of the fiber. The number of colors used on the fiber depends on the desired designs to be woven. For instance, if three designs are to be woven simultaneously on a carpet's surface, fewer colors will be used compared to weaving four designs at the same time. To determine the placement of these designs within each knot, the first design should be placed on the edge of the knot. The colors for the rotating design would occupy one-seventh of the edge of the knot, followed by the colors for the geometric design in the second seventh (the middle part of the knot), and finally the colors for the modern design in three-sevenths of the end of the knot. In other words, each part of the knot is specific to a different design (Fig. 11 ).

[0040] This method of layering designs and colors on the surface of the carpet allows for more intricate and complex patterns to be created. By dividing the knot into different sections and assigning specific colors to each section, a variety of designs can be woven simultaneously on the carpet's surface.

[0041] For example, if the knot is divided into twelve parts, there can be two to five designs and colors on the surface of the carpet. Each design and color is placed on a specific layer within the knot. The first design occupies the first twelfth of the knot, the second design occupies the second twelfth, and so on. The fifth design is placed in the center of the knot, occupying four-twelfths of the space.

[0042] This layered method can be applied to both machine-woven and handwoven carpets. It allows for more creativity and flexibility in designing carpets, as multiple designs and colors can be incorporated into a single piece. The number of designs and colors used in the entire carpet will depend on the desired complexity and intricacy of the final design.

[0043] Color and dot map: The color and dot maps used previously in carpet weaving each contained a single design. However, in order to accommodate multiple designs within a checkerboard pattern, a new approach is required. Specifically, since all three designs are woven simultaneously on the same surface of the carpet and each knot contains three different colors, it is necessary to divide each square of the checkerboard horizontally into three equal parts. Each color is then placed in the desired design's sequence. The colors of the first design are positioned at the beginning of each section, the colors of the second design are placed in the middle section, and the colors of the third design are placed at the end section of each square(29) (As shown in Fig. 13). To achieve a texture with five designs simultaneously in each knot, grid paper with horizontal divisions and a specific number of rows per square is required. In this method, the colors of each design are arranged from bottom to top within each square (as shown in Fig.14).

[0044] Alternatively, a vertical approach can be used for painting and dotting. This method is suitable for two-way colored fibers. In this case, each checkered square is divided vertically into two parts, and the colors of the first design are placed on the right side while the colors of the second design are placed on the left side of the square (as shown in Fig. 15). This technique allows the weaver to have complete control over both designs simultaneously.
