Definitions

  • the invention relates to carpet viewing and specifically discloses a multidesign carpet weaving method for any type of carpet.
  • the weaver starts by knotting the yarn around pairs of warp threads to create the desired pattern.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • FIGS. 1 , 2, and 3 show the steps of weaving the knot around the wraps.
  • FIG. 4 shows the view of the placement of knots and wefts from the front of the carpet.
  • FIG. 5 shows the top view of the knot and the angle and direction of rotation of the knot.
  • FIG. 6 shows the knot placement of the knot on the wraps.
  • FIG. 7 shows the position of knots and thick and thin weft on the wraps.
  • FIG. 8 shows the top view of the position of the knots on the wraps.
  • FIG. 9 shows the position of each design on the yarn.
  • FIG. 10 shows one embodiment method for coloring two-color yarn.
  • FIGS. 11 &12 show the placement of design and color on each yarn in a layered method.
  • FIG. 13 shows the color and horizontal dot method, where three different design models are placed together horizontally.
  • FIG. 14 shows a square of checkered paper in which the colors are placed horizontally.
  • FIG. 15 shows color and dots in a vertical way, as well as a square of checkered paper, in which the colors are placed in a vertical way.
  • FIG.16 shows a double-sided carpet with four different designs, two designs are placed on the upper surface and two designs are placed on the lower surface of the carpet, and the designs change by touching the carpet.
  • FIG. 17 shows a carpet whose design is changing on the face of the carpet.
  • FIG. 18 shows a carpet with ten different designs, five of which are on the upper surface and five on the lower surface of the carpet, which are placed and woven into one carpet at the same time. Also, the location of the designs on the surface of the pile of the carpet is displayed
  • 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):
  • 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).
  • 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.
  • the fiber substance is positioned in a U-shaped and horizontal manner behind the wrap.
  • a hook(3) is inserted from the back into the loop of the thread.
  • 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 ).
  • the fiber is then brought to the loop and rotated 180 degrees within that specific section.
  • 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.
  • 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.
  • the tail is brought over the carpet passed through the loop head, and pulled slightly to tighten the knot.
  • 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.
  • the thick weft(7) is passed and then the thin weft(8) between the warps(1 ) (Fig. 7).
  • 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).
  • the second method involves changing the colors of the fibers to achieve layered designs on the knot's surface.
  • each knot could only create a specific design, limiting the options for design and color.
  • 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.
  • each part of the knot is specific to a different design (Fig. 11 ).
  • 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.
  • 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.
  • 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.
  • 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).
  • a vertical approach can be used for painting and dotting.
  • This method is suitable for two-way colored fibers.
  • 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.
  • This method can be implemented on all kinds of carpets and rugs in different sizes and with different threads of silk, linen fluff and other common materials in the carpet industry.

Abstract

La présente invention concerne un tapis qui a la capacité de changer de couleur et de conception par manipulation de la direction de la couche pelucheuse. Le tapis est constitué de chaînes, la distance entre elles étant ajustée pour correspondre à l'épaisseur d'une à deux couches pelucheuses. Un noeud est incorporé sur une chaîne, permettant un état de rotation bidirectionnel à l'intérieur du noeud et créant une direction de la couche pelucheuse gauche et droite sur la surface de tapis. Ceci permet aux clients de modifier la conception du tapis en changeant la direction de la couche pelucheuse. Le procédé de tissage de ce tapis consiste à espacer les chaînes, à régler leur distance sur la base de l'épaisseur de la touffe, à teindre les fibres de touffe, à former des noeuds sur chaque chaîne à l'aide d'une substance fibreuse, à tisser les noeuds ensemble entre les chaînes, et à faire passer des trames épaisses et minces entre les chaînes après chaque rangée de tissage.
