Description

I242620 A7 B7 V. Ministry of Consumers, India, India, India, and India (1) The invention relates to papermaking and related technologies. More specifically, the invention is an industrial fabric that can be sewn on a machine: a press fabric that can be sewn on a machine. In a manufacturing process called deposition, fiber materials are used to form -fibers, fiber bundles, that is, one of the forming parts of a paper machine is moved to i fabric to eliminate these fibers. In water. A large amount of water is removed by the slurry passing through the forming fabric, leaving the fibers on the surface of the forming fabric. The bamboo rafter is placed ... The freshly formed fibrous material rafter will advance from the forming part to a pressing ceremony 'which is a pressing and rolling part containing U. The fibrous material may pass through the crimped parts supported by a crimped fabric, or, as usual, between two crimped fabrics. In such press-rolled products, the fibrous material 疋 will be subjected to a compressive force ', which will squeeze out water and cause the fibrous materials in the material to stick to each other, so that the fibrous material 疋 becomes a paper. This moisture will be received by the fabric, etc., and ideally, it will not flow back into the paper. The paper eventually advances to a drying section, which contains at least one set of rotatable drying drums or cylinders, which is heated internally by steam. Freshly made paper is dried by a fabric in order to bypass the relocation path of the series of drums, which will hold the paper against the surface of the drums. These heated drums reduce the moisture of the paper to a desired level through evaporation. Please understand that these formed, crimped and dried fabrics are used on paper machines in endless form and have the function of conveyor belts. It should be understood that the paper manufacturing is a continuous process, and the paper is fed at a relatively fast speed. The paper size applies the Chinese National Standard (CNS) A4 specification (2W χ Norwegian public hair γ 4-1242620 A7 5 2. Description of the invention (2) The Ministry of Economic Affairs and Intellectual Property Bureau of the Ministry of Economic Affairs and the Ministry of Economic Affairs and the Ministry of Economic Affairs and the Ministry of Economic Affairs and the Ministry of Economic Affairs and the Ministry of Economic Affairs have formulated this situation. After the part is dried, it will be continuously rolled up on the roller. Please note that the special pressed fabric is only supplied for a period of time by endless lifting. This is because of the newly formed fibers The material is very sensitive and vulnerable to any inconsistency in the pressed fabric in the rolled product.-Endless and seamless fabrics, such as those made by endless weaving, will be in their longitudinal direction (along the machine direction). ) Has a consistent structure with the transverse direction (cross machine direction).-Seam 'For example, when the pressed fabric is installed on a paper machine, it can be closed into an endless form of seam, which represents the pressure. Interruption of the consistent structure of the fabric. The use of _ seams will greatly increase the possibility of the fibrous material being embossed in the press roll. For this reason, any seam area that can be used to press the fabric on the machine can be sewn on the table. Must be able to operate under heavy pressure, gp, can not be different from the rest of the pressed fabric under the compression of the rolled product, and must also have the same water and air as the rest of the pressed part The permeability of the paper product can prevent the paper products from periodically showing the marks caused by the seam area. Although these requirements have shown considerable technical obstacles, there is still a high need to develop a The crimped fabric stitched on the machine, because these can be easily and safely installed on the crimped part. Finally, the obstacle is overcome by the newly developed crimped fabric, which has The seams are formed by arranging sewing loops at the lateral edges of the fabric at both ends. The constant sewing loop itself is made of the fabric's machine direction (MD) yarns. The sewing rings overlap each other, and a weaving system This paper scale applicable Chinese National Standard (CNS) A4 size (210 X 297 mm)

Description of the invention ('Pivot line' through the channels formed by the overlapping sewing rings to make the two ends of the fabric j: a ϋ jIL · ring and join together ' The two ends are joined to make the 4 seams _. Needless to say, this is easier and less time-consuming than knitting the endless pressed fabric, and it takes less time to install one that can be installed on the machine σ Stitched crimped fabric. This kind of crimped fabric that has these seams and can be joined on a paper machine is a plain weave. In this case, the warp yarn is λ c Yarn of the fabric in the machine direction (md). To make such sewing loops, the warp yarn at the end of the fabric will be turned back and woven back into the fabric body at a certain distance in a direction parallel to the warp yarn Another better technology is the correction method of endless weaving. The endless weaving method is normally used to make an endless fabric loop. In the modified endless weaving method, the weft yarn or filling yarn is Continuously weaving across the loom and back and forth, at the edges of both ends of the fabric— On the other hand, by bypassing the loop-forming needle, a loop is formed on each pass. Because such weft yarns, or stuffing yarns, will eventually become the MD yarns in the pressing, they are continuous, so The% stitching made in this way will be stronger than anything that can be made by weaving the ends of the warp yarn back to the ends of a plain woven fabric. First, separate single-fiber strands were used in the machine. The upper stitching presses the fabric in the machine and cross machine directions. The relative stiffness of the single fiber will indeed give it the excellent properties required to form a sewing loop. However, experience has shown that individual single fiber strands are difficult to weave And for many kinds of current processes, there is insufficient elasticity in the machine direction. Therefore, tensile failures and seam fractures often occur. ------------------- Order --------- (Please read the notes on the back before filling this page)

Description of the invention (4) Another difficulty is woven by separate single fibers The resulting bottom fabric is very open, rigid and incompressible. This incompressibility is not a problem in some papermaking applications, and may even be ideal. However, it has poor auxiliary fabric dehydration capabilities. Where, or when making paper grades that are sensitive to marks, a softer, more compressible backing fabric is required. A more compressible backing fabric can be woven from multi-fiber yarns or plied single-fiber yarns, and Replaces those made with separate single-fiber strands. However, these yarns do not have the ability to properly form a loop or to maintain the integrity of the seam area when the seam is closed so that the jade overlaps The rigidity required by the yarns. Because these yarns are twisted, the loops formed by them tend to rotate around the axis on the plane formed by the loops. When This was When a rotation called a second helix occurs, it will cause the loops to rotate away from the ideal orientation required for the overlap. The deflections will make it difficult, if not impossible, to place the two End loops, properly overlapping each other when closed, and guiding the pivot line through the channels formed by these overlapping loops. Various attempts have been made in the conventional technology to borrow non-mono fibers The loop MD yarns are made like single-fiber yarns to overcome these difficulties. In US Pat. No. 5,056,610, MD yarns on a paper machine fabric that can be sewn on a machine have a composite structure and include braiding. The knitting yarn will form a sewing loop, because it is balanced for twisting, so it can prevent the moxa shape and make these sewing loops not sensitive to the second spiral action.

In the technical fabric of the present invention, the purpose can be achieved, which is a composite yarn as the auxiliary yarn, @ contains most of the individual yarn strands, and at least one fusible strand of raw materials ... The thermoplastic material of the at least one fusible strand has a melting point that is lower than the melting point of each of the yarn strands in the composite yarn. Therefore, once heat treatment is applied to a composite yarn of any predetermined length, at a temperature higher than the melting point of the fusible strand, but lower than the melting point of the individual yarn strands, the 4 thermoplastic material will melt and flow to each yarn. The gap between the strands, and when the heat treatment is completed, the composite yarn can be consolidated and hardened, and the individual yarn strands are joined together along the predetermined length. This will ensure that the sewing loops made from these composite yarns will remain properly positioned and required integrity for sewing. In addition, the inclusion of one or more fusible strands in the composite yarn allows the hardness of the yarn to be controlled in accordance with the number and / or size of the fusible strands included. Moreover, this will allow the fabric to be more compressible and more elastic than a fabric made from yarns without fusible strands, which will allow greater privacy control. These composite yarns may be plied single-fiber yarns, plied multi-fiber yarns, multi-fibers,: /, or combined / checked yarn 'or a combination thereof. A single-ply / inspection yarn refers to any kind of yarn used in the manufacture of paper machine fabrics, which has most of the filaments grabbed to a required degree, and in many cases, the combination with its paper size applies to the Chinese country Standard (CNS) A4 specification (210 X 297 mm) -------- tr --------- (Please read the precautions on the back before filling this page) 9 1242620 A7 Ministry of Economy Wisdom Printed by the Consumer Cooperative of the Property Bureau V. Invention Description (7 It is the same or different kind of filament combination or ply. When the ply operation is performed, these yarn strands will be twisted and combined in the opposite direction of the individual strands. Together. Such plied / twisted yarns can therefore be considered as composite yarns. Or the composite yarns can also be knitted or woven yarns. However, in any case, the composite yarns will contain at least one fusible yarn The individual yarn strands included in the composite yarn are typically circular in cross-section. It should be understood that they can also have any other cross-sectional shape, such as rectangular, that is, shaped or polygonal.
