Abstract

A papermaking felt employing an endless structure is provided which is reduced in equipment and production costs. The base of the felt has high strength of bonding between yarns arranged in parallel. The felt is excellent in processability and in suitability for water removal and the property of smoothing the surface of a wet web. Warps each having a heat-fusible yarn wound thereon at a constant pitch are arranged in parallel to form parallel yarns, and the parallel yarns are heated to fix the warps to each other and form an endless structure constituted only of the warps. A butted layer is superposed on the endless structure and united thereto by entangling by needle punching to thereby produce the felt for papermaking.

The laminated wet paper side batt layer (1〇5) and the roll side batt layer Π06) The base material layer (101) is integrally formed by interlacing the base material layer and the (101) and the batt layer by needle punching. Further, in the tenth figure, as a preferred example, the batt layer is disposed on the base material layer ( The two sides of 101) can be disposed at least on the side of the wet paper side. The eleventh figure is the eighth type of the felt for papermaking of the present invention, and the cross-sectional view of the CMD direction. As shown in the eleventh figure, the felt for papermaking (n) having: a base material layer (11) having a woven fabric (113) disposed adjacent to the flaky nonwoven fabric (114); wherein the flaky nonwoven fabric ("4)f and the non-terminal structure ( N2) combination; the non-terminal structure (Π2) is formed by arranging the yarns of the entangled yarn (丨3) in parallel with 10 200938694. The laminated wet paper side batt layer (u layer (10)) is The substrate layer (111) is integrally formed by stitching (11:) with the batt layer. In addition, the fabric (]] / :: uses a simple fabric that is not time-consuming to weave, for example, CMD ancient: life It can also be a woven fabric with the same width as the first use of the bristles for papermaking, or it can be used wider than the above. The width of the narrower width is woven, and the width of the CMD direction of the papermaking felt is the same width. In addition, in the eleventh figure, the batt layer is disposed on the substrate layer as a preferred example. ((1)) It can be placed on the side of the wet paper side. 彳-Main 乂: used as the yarn of the substrate of the present invention and the fiber used for the batt layer: material, can be used for paper machine roll embossing f from nylon , polyester vinegar, polypropylene, natural materials, etc. The core yarn of the entangled yarn can be used with high melting point nylon 6, nylon 66 nylon (four), nylon 612 'or polyester (ρΕτ), ρρ qing, fang (four) polyamine, etc. . As the type of the core yarn, a single fiber yarn, a single fiber yarn, or a composite fiber can be used. As: :: In the core yarn of the wrapped yarn of the present invention, a mixed yarn (single fiber, crepe) is used. That is, the entangled yarns are aligned, and the piles of the short fiber yarns are mutually misaligned in parallel, and the bonding force of the yarn rows of the yarns can be wrapped. ^ 200938694 As the hot melt yarn, a yarn having a lower melting point than the above-mentioned core yarn, such as polyethylene, polypropylene, copolyester, copolymerized nylon or the like can be used. Binary copolymerized nylon such as nylon 6/12, nylon 6/610, nylon 66/6, nylon 66/12, nylon 66/610, nylon 6/66/12, nylon/66/61 〇 special binary nylon The fiber of the yarn or the staple fiber yarn is preferred. Further, it is known that these copolymerized nylons have different melting points depending on the composition (% by weight of the copolymerization component), and can be used in the copolymerized nylon of the present invention, wherein the melting point is 18 (TC or less, preferably 130 ° C or less). As the non-woven fabric, a sheet-like fiber assembly which can be produced by a method such as spunbonding, melt-blown or non-woven fabric, and a material for the sheet-like nonwoven fabric is preferably the same as the above-mentioned hot-thin fusion yarn. The first diagram shows the wrapped yarn (Fig. 3) constituting the endless structure of the present invention. The second wrapped yarn (degree ratio 4 is compared with the hot melt wrapped yarn (hot melted yarn hot melted yarn core) In the figure, 13) of the coreless yarn (n) constituting the endless structure of the present invention and the fiber of the hot melt yarn (12) are in the range of 5:1 to 8:1. Preferably, the yarn is wound at equal intervals in the range of 100 turns/m~20_/m, preferably in the range of 500 turns/m~_turn~] 3). In addition, in the first figure, relative to the core yarn (n), Π 2) Rolling in the Z direction, but with respect to the core yarn (]]), Π 2) can also be wound in the S direction. Then, in the present invention 200938694, as shown in the second figure, the plurality of wrapped yarns (13) are drawn into a yarn array (22) by a cyanine sheet (21), and one end of the yarn row is fixed; The endless belt for guiding the column (24) wherein the heat exchangers (24) are arranged at a distance from one of the pair of mutually parallel rollers (23). /, - Person, As shown in the second figure, because if you put the 艮1, 丨1 print "; π not on the upper return roller along

❹ Then the direction of the head (A) is rotated, and the yarn row (22) whose one end is fixed to the endless belt (μ) will be sucked in. Therefore, the yarn is arranged sideways (gradually toward the width direction (ie, the arrow direction (B)) The moving side is supplied to the yarn row (22), and the yarn row (22) is spiraled to present a spiral shape. After the yarn row (22) becomes a predetermined width of the felt, the yarn is stopped (supply the yarn string (22)' and then hot air or It is a heat source such as infrared rays, which is processed first, and the hot melt yarn is melted to fix the yarn array, and a non-terminal structure in which the yarns are arranged in a bundle of yarns is obtained, and a sheet-like non-woven fabric is disposed adjacent to the yarn array. With hurricane: outside: heat treatment such as heat source 'fixed yarn column and flaky shape; : ' can also be obtained in parallel configuration of wrapped yarns without terminal structure. /~< Another example is the brother S map #, if丨 纱 列 列 列 : : : : : : : : : : : : : : : : : : : 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱 纱Sound eight ^ keep - set the tilt angle and () () 'but considering the money for papermaking The walking 200938694 0 is ίο.

In addition, the total production time of all the substrates at the time of preparation of the base material of the substrate is as follows: = system: in "felt on the table". The relative ratio is as follows: the ratio of the clothes of the soil indicates the relative ratio = D / d X 1 〇〇D • The total production time of the base layer of each of the bristles ❹ · ^ · The base layer of Comparative Example 1 Total between the [Table 1]

As shown in Table 1, the examples -8 to 8 are arranged in the base material layer by the non-terminal structure formed by the heat f melting of the f, so that the beginning of the hair is changed to the south and the warp and weft are not In the case of the cross-section, the rolling portion was repeatedly distributed by the average of the parts, so that the wet paper was more water-soluble than Comparative Example 1 in which the substrate was made of a woven fabric. Also, similarly, the printability is also improved. In addition, regarding the processability of the non-terminal structure, there is no fracture at the time of production and hanging on the needling machine, and it is possible to

For no end, no terminal shape, no terminal shape, 200938694 Short-time production of a non-terminal structure, greatly reducing working hours. INDUSTRIAL APPLICABILITY According to the present invention, it is possible to obtain a strong yarn binding force of a non-terminal structure obtained by winding a hot-melt yarn, and processing:::, wet paper surface, squeeze Papermaking felt with excellent water-based properties and a woven base material.
