X, ○, Δ and ▲ marks indicate knuckles. These notations are also used in FIG. 3 and subsequent figures.

The industrial fabric 10 according to the first embodiment shown in FIG. Lower surface composed of warp yarns (1L to 8LB) and lower surface side weft yarns (1′L, 3′L, 5′L, 7′L, 9′L, 11′L, 13′L, 15′L) The side woven fabric is connected.

The upper surface side warps (1U to 8U) and the lower surface side warps (1L to 8LB) are 8 each in the complete weave, and the upper surface side wefts (1'U to 16'U) are 16 in the complete weave, There are 8 bottom side wefts (1'L, 3'L, 5'L, 7'L, 9'L, 11'L, 13'L, 15'L) in the complete weave. Two of the eight lower side warps (1L to 8LB) in the complete weave function as lower side binding yarns (4LB, 8LB) that bind the upper side fabric and the lower side fabric.

Next, how to weave each warp and each weft in the industrial fabric 10 will be described with reference to FIGS. 2(a) and 2(b). The arrangement of the upper surface side wefts and the lower surface side wefts shown in FIGS. 2(a) and 2(b) is the same.

FIG. 2(a) shows a configuration in which a set of upper surface side warp yarns 3U and lower surface side warp yarns 3L are woven into upper surface side weft yarns and lower surface side weft yarns. As shown in FIG. 2(a), the upper surface side warp 3U passes over one upper surface side weft (4'U, 8'U, 12'U, 16'U), and three continuous upper surface side A weaving pattern passing under the weft threads (1'U to 3'U, 5'U to 7'U, 9'U to 11'U, 13'U to 15'U) is repeatedly formed, so-called 1/3 Forms an interwoven pattern of tissue. Four knuckles are formed on the surface of the upper side fabric by the upper side warp 3U passing over one upper side weft (4'U, 8'U, 12'U, 16'U).

The upper surface side warps (1U, 2U, 5U to 7U) include upper surface side warps (1'U to 16'U) to form a 1/3 weave weave pattern. In this way, the upper surface side warps (1U to 3U, 5U to 7U) form a weaving pattern of the same 1/3 structure, and the upper surface side wefts (1′U to 16′U) are knuckles at regular intervals. and is woven without destroying the surface texture. Upper surface side warps (1U to 8U) are not woven into lower surface side wefts.

The bottom side warp 3L passes under one bottom side weft 5′L, passes over two continuous bottom side wefts (7′L, 9′L), and passes one bottom side weft 11. A weaving pattern of 1/2-1/4 weave passing under the 'L and passing over the four continuous bottom side wefts (1'L, 3'L, 13'L, 15'L) Form. The lower surface side warps (1L, 2L, 5L to 7L) have the same weaving pattern as the lower surface side warp 3L, although the weaving position is shifted in the warp direction from the lower surface side warp 3L. Form a 1/4 weave weave pattern.

FIG. 2(b) shows a configuration in which a pair of upper surface side warp yarns 4U and lower surface side binding yarns 4LB are woven into upper surface side weft yarns and lower surface side weft yarns. The upper surface side warp yarns 4U and the lower surface side binding yarns 4LB form a set facing each other vertically and cross each other for binding.

The upper surface side warps 4U pass over the upper surface side wefts (2'U, 10'U, 14'U) to form knuckles, respectively, and the upper surface side wefts (1'U, 3'U to 9'U, 11'U). 'U to 13'U, 15'U, 16'U). That is, the upper surface side warp 4U sequentially passes over one upper surface side weft 10′U, passes under the three continuous upper surface side wefts (11′U to 13′U), and passes under one upper surface side weft. It passes above the side weft 14'U, passes below three continuous top side wefts (1'U, 15'U, 16'U), and passes above one top side weft 2'U. , to form a weaving pattern passing under the seven continuous upper surface side wefts (3′U to 9′U). The upper surface side warp yarns 8U form a weaving pattern similar to that of the upper surface side warp yarns 4U, although their weaving positions are shifted in the warp direction from the upper surface side warp yarns 4U.

The lower side binding yarn 4LB passes under one lower side weft 11'L, passes under two continuous lower side wefts (13'L, 15'L), and passes under one lower side weft. A 1/2-1/4 structure that passes under the side weft 1'L and passes over the four continuous lower side wefts (3'L, 5'L, 7'L, 9'L) Form a weave pattern. That is, the lower surface side binding yarn 4LB is woven without destroying the weaving pattern of the lower surface side fabric. The lower side binding yarn 4LB forms a knuckle N1 passing above the upper side weft 6'U for binding, and the upper side weft (1'U to 5'U, 7'U to 16'U) pass below. The bottom side binding yarn 8LB forms the same weaving pattern as the bottom side warp yarn 4LB, although the weaving position is shifted in the warp direction from the bottom side binding yarn 4LB.

The upper surface side warp 4U, which is paired vertically with the lower surface side binding yarn 4LB, passes under the upper surface side weft 6′U at the position where the lower surface side binding yarn 4LB passes above the upper surface side weft 6′U. It does not form a knuckle and functions as a breaking thread. In addition, the upper surface side warp 8U, which is paired vertically with the lower surface side binding yarn 8LB, passes under the upper surface side weft 14′U at the position where the lower surface side binding yarn 8LB passes above the upper surface side weft 14′U. It functions as a breaking thread to pass through.

A set of lower side binding yarns (4LB, 8LB) and breaking yarns (4U, 8U) passes above one upper side weft on the surface of the upper side fabric and is below three continuous upper side wefts. forming a weave pattern through the That is, the sets of the lower side binding yarns (4LB, 8LB) and the breaking yarns (4U, 8U) cooperate to form a weaving pattern of ⅓ weave on the surface of the upper side fabric. This allows the entire surface of the top fabric to be formed with a 1/3 weave pattern. By forming a 1/3 weave pattern on the surface of the upper surface side fabric, the portion where the upper surface side warp threads protrude to the surface side can be reduced, and the influence of abrasion can be suppressed. In addition, since the 1/3 weave has less bending of the warp than the plain weave (1/1 weave), a large number of top side wefts can be woven, and by increasing the number of top side wefts, paper fibers can be supported. It is possible to improve the yield of the paper and obtain good formation.

The upper surface side warps 4U and the lower surface side binding yarns 4LB mutually complement the surface texture of the upper surface side fabric, so that they are similar to the upper surface side warps (1U to 3U, 5U to 7U) other than the upper surface side warps 4U (breaking threads). , and the same number of knuckles as the upper surface side warp yarns (1U to 3U, 5U to 7U) other than the breaking yarn 4U are formed on the upper surface side surface texture. In this way, the set of the breaking thread 4U and the lower side binding thread 4LB complement each other to form a weaving pattern for one upper side warp and one lower side warp, respectively. In addition, by knotting with a combination of the breaking yarn 4U and the bottom side binding yarn 4LB, deterioration of the surface properties can be suppressed compared to the case where the upper and lower binding warp pairs are provided. Also, the set of upper surface side warp yarns 8U and lower surface side binding yarns 8LB has the same effect as the set of upper surface side warp yarns 4U and lower surface side binding yarns 4LB.

Knuckles formed on the surface of the upper fabric by passing the upper warps (1U to 8U) and the lower binding yarns (4LB, 8LB) above the upper wefts (Fig. 1 ) are not evenly arranged in the oblique direction. Further, the knuckles formed on the surface of the upper surface side fabric include those having a displacement of one upper surface side weft and a displacement of two upper surface side wefts in the warp direction between adjacent upper surface side warps. The knuckles formed by four upper surface side warps arranged in the weft direction are formed in different upper surface side wefts for each upper surface side warp. For example, the knuckle Na formed by the upper surface side warp 1U and the upper surface side weft 1′U, the knuckle Nb formed by the upper surface side warp 2U and the upper surface side weft 3′U, the upper surface side warp 3U and the upper surface side weft 4′. The knuckle Nc formed by U and the knuckle Nd formed by the upper surface side warp 4U and the upper surface side weft 2′U are both formed on different upper surface side wefts. The knuckle Na of the upper surface side warp 1U and the knuckle Nb of the upper surface side warp 2U have a displacement of two upper surface side wefts in the warp direction. A knuckle Nc of the upper surface side warp 3U and a knuckle Nd of the upper surface side warp 4U have a displacement of two upper surface side wefts in the warp direction. The four upper surface side warps (1U to 4U) arranged in the weft direction form knuckles on different upper surface side wefts. Since the knuckles formed on the surface of the upper side fabric are not diagonally aligned, it is possible to suppress the occurrence of oblique marks on articles manufactured with the industrial fabric 10 . By forming a weaving pattern on the surface of the upper side fabric with a broken 1/3 structure, the upper side warp and the lower side warp are a multiple of 4 shafts, and a multiple of 8 shafts. It can be combined with a 1/4 weave weave pattern. As a result, the number of wefts on the upper surface side is increased to improve the fiber supportability and yield, and to form a woven fabric having excellent abrasion resistance.

The sets of lower binding yarns (4LB, 8LB) and breaking yarns (4U, 8U) are 1/2- Form a 1/4 weave weave pattern. As a result, a weaving pattern of 1/2-1/4 weave can be formed on the surface of the lower fabric. As a result, the portion of the lower surface side warp exposed on the surface of the lower surface side fabric can be reduced, and the influence of abrasion can be suppressed. The 1/4 weave can suppress bending of the woven warp yarns.

The bottom side binding yarn 4LB passes over four continuous bottom side wefts (3'L, 5'L, 7'L, 9'L) in the weaving pattern of the 1/2-1/4 weave. In between, a knuckle N1 for knotting is formed through the upper side of the upper surface side weft 6'U. In particular, the bottom side binding yarn 4LB forms the knuckle N1 at the central position of the area of four continuous bottom side wefts (3'L, 5'L, 7'L, 9'L). As a result, it is possible to prevent the lower side binding yarn 4LB from strongly pulling in the upper side weft 6'U. The bottom side binding thread 8LB also has the same effect as the bottom side binding thread 4LB.

The bottom side warp yarns (1L-8LB) pass under the same bottom side weft yarn with the adjacent bottom side warp yarns on the left or right side. That is, two circle marks shown in FIG. 1 are arranged side by side in the weft direction. In addition, the bottom side warps (1L to 8LB) form a knuckle passing under the same bottom side weft together with the bottom side warp adjacent to the left side, and the bottom side of the same bottom side weft together with the bottom side warp adjacent to the right side. and knuckles forming through the . For example, the bottom side warp 3L weaves the same bottom side weft 5'L together with the bottom side warp 2L located on the left side, and then the same bottom side weft 11'L together with the bottom side warp 4LB located on the right side. In this way, the lower surface side warp yarns are paired on the left and right sides, and the same lower surface side weft yarns are woven. As a result, the interval at which the lower side warp weaves the lower side weft becomes longer, and while the lower side warp is pulled in, the lower side weft largely protrudes from the surface of the lower side fabric, resulting in a large abrasion volume and abrasion resistance. improve sexuality.

A plurality of lower surface side binding yarns (4LB, 8LB) are arranged at equal intervals across three lower surface side warp yarns (1L to 3L, 5L to 7L) that are not binding yarns. As a result, the lower surface side binding yarns (4LB, 8LB) can be evenly spaced apart from each other, and biased binding positions in the weft direction can be suppressed.

The position where each of the two lower surface side binding yarns (4LB, 8LB) in the complete weave passes over the upper surface side wefts (6′U, 14′U) is the position where the eight upper surface side wefts are displaced in the warp direction. be. That is, the knuckle N1 formed by the lower side binding yarn 4LB on the upper side weft 6'U and the knuckle N1 formed by the lower side binding yarn 8LB on the upper side weft 14'U are eight upper surfaces in the warp direction. There is a deviation of the side wefts. As a result, in the industrial fabric 10 having 16 upper surface side wefts, the knotting positions can be evenly spaced apart in the warp direction, and biased knotting positions in the warp direction can be suppressed. Also, the number of knuckles can be reduced while the knuckles for joining are spaced evenly. By dispersing the bonding positions in this way, it is possible to suppress the deterioration of the surface properties and suppress the disturbance of the texture of the paper produced.

For example, the bottom side weft 3'L passes under six continuous top side warps (1L to 6L). As a result, a large amount of the lower surface side wefts are exposed on the surface side of the lower surface side fabric, and abrasion resistance can be improved.

The wire diameter of the lower side weft may be set in the range of 1.5 to 2.5 times the wire diameter of the upper side weft. As a result, the wire diameter of the lower surface side weft can be increased to improve wear resistance.

The lower surface side weft may be composed of a mixed weave of a wire made of polyethylene terephthalate resin and a wire made of polyamide resin. Thereby, the wear resistance can be improved while increasing the strength of the lower side fabric.

The number of meshes [number/inch] of the upper surface side wefts may be greater than the number of meshes [number/inch] of the upper surface side warps. This improves the support of the paper fibers.

[Second embodiment]
FIG. 3 is a design diagram showing the complete design of the industrial fabric 20 according to the second embodiment. FIG. 4 is a cross-sectional view in the warp direction along the warp in the design drawing shown in FIG.

Two of the eight lower side warps (1L to 8LB) in the complete weave function as lower side binding yarns (4LB, 8LB) that bind the upper side fabric and the lower side fabric.

Next, how to weave each warp and each weft in the industrial fabric 20 will be described with reference to FIGS. 4(a) and 4(b). The arrangement of the upper surface side wefts and the lower surface side wefts shown in FIGS. 4(a) and 4(b) is the same.

FIG. 4(a) shows a configuration in which a pair of upper surface side warp yarns 3U and lower surface side warp yarns 3L are woven into upper surface side weft yarns and lower surface side weft yarns. As shown in FIG. 4(a), the upper surface side warp 3U passes over one upper surface side weft (1'U, 5'U, 9'U), and three continuous upper surface side wefts (2' U-4'U, 6'U-8'U, 10'U-12'U) are repeatedly formed to form a so-called 1/3 weave pattern. Three knuckles are formed on the surface of the upper side fabric by the upper side warp 3U passing over one upper side weft (1'U, 5'U, 9'U) respectively.

The upper surface side warps (1U, 2U, 5U to 7U) include upper surface side warps (1'U to 12'U) to form a 1/3 weave weave pattern. In this way, the upper surface side warps (1U to 3U, 5U to 7U) form a weaving pattern of the same 1/3 structure, and the upper surface side wefts (1′U to 12′U) are knuckles at regular intervals. and is woven without destroying the surface texture.

The upper surface side warp yarns 4U and the lower surface side binding yarns 4LB form a set facing each other vertically and cross each other for binding.

The upper surface side warps 4U pass above the upper surface side wefts (2'U, 6'U) to form knuckles, respectively, and the upper surface side wefts (1'U, 3'U to 5'U, 7'U to 12 'U). That is, the upper surface side warp 4U sequentially passes over one upper surface side weft 2′U, passes under the three continuous upper surface side wefts (3′U to 5′U), and passes under one upper surface side weft. A weaving pattern is formed that passes over the side weft 6′U and under seven continuous top side wefts (1′U, 7′U to 12′U).

The lower side binding yarn 4LB passes under one lower side weft 1'L, passes under two continuous lower side wefts (2'L, 4'L), and passes under one lower side weft. Passing under the side weft 5'L and passing over the four continuous lower side wefts (7'L, 8'L, 10'L, 11'L), 1/2-1/4 weft Form a weave pattern. That is, the lower surface side binding yarn 4LB is woven without destroying the weaving pattern of the lower surface side fabric. The lower side binding yarn 4LB forms a knuckle N1 passing above the upper side weft 10'U for binding, and the upper side weft (1'U to 9'U, 11'U to 12'U). pass below. The bottom side binding yarn 8LB forms the same weaving pattern as the bottom side warp yarn 4LB, although the weaving position is shifted in the warp direction from the bottom side binding yarn 4LB.

The upper surface side warp 4U, which is paired vertically with the lower surface side binding yarn 4LB, passes under the upper surface side weft 10′U at the position where the lower surface side binding yarn 4LB passes above the upper surface side weft 10′U. It does not form a knuckle and functions as a breaking thread. On the other hand, the lower side binding yarns 8LB are paired with the upper side warp yarns 1U. The upper surface side warp yarns 1U paired with the lower surface side binding yarns 8LB will be described with reference to new drawings.

FIG. 5 is a design drawing of the industrial fabric 20 of the second embodiment, which is developed in the weft direction. In FIG. 5, the upper surface side warp and the lower surface side warp are arranged alternately.

By the way, the lower surface side binding yarns (4LB, 8LB) intersect the upper surface side warp yarns for binding and pass between the adjacent upper surface side warp yarns. That is, the knuckles (N1, N2) formed by the lower binding yarns (4LB, 8LB) have upper surface warps located on the left and upper surface warps located on the right.

The bottom side binding yarn 4LB is paired with the top side warp yarn 4U located on the left side, while the bottom side binding yarn 8LB is paired with the top side warp yarn 1U located on the right side. Although the weaving position of the upper surface side warp yarns 1U is shifted in the warp direction from that of the upper surface side warp yarns 4U, the upper surface side warp yarns 1U form the same weaving pattern as the upper surface side warp yarns 4U, and the lower surface side binding yarns 8LB are above the upper surface side weft yarns 4'U. It functions as a breaking thread passing under the upper surface side weft 4'U at the position passing through the upper surface side weft 4'U.

The other lower surface side binding yarn 8LB is positioned to the left of the other breaking yarn 1U. Thereby, the breaking thread can be arranged on the left and right sides of the lower surface side binding thread.

Return to FIG. A set of lower side binding yarns (4LB, 8LB) and breaking yarns (4U, 1U) passes above one upper side weft on the surface of the upper side fabric and is below three continuous upper side wefts. forming a weave pattern through the That is, the sets of the lower side binding yarns (4LB, 8LB) and the breaking yarns (1U, 4U) cooperate to form a weaving pattern of ⅓ weave on the surface of the upper side fabric. This allows the entire surface of the top fabric to be formed with a 1/3 weave pattern.

The upper surface side warps 4U and the lower surface side binding yarns 4LB mutually complement the surface texture of the upper surface side fabric, so that they are similar to the upper surface side warps (2U to 3U, 5U to 8U) other than the upper surface side warps 4U (breaking threads). , and the same number of knuckles as the upper surface side warp yarns (1U to 3U, 5U to 7U) other than the breaking yarn 4U are formed on the upper surface side surface texture. In this way, the set of the breaking thread 4U and the lower side binding thread 4LB complement each other to form a weaving pattern for one upper side warp and one lower side warp, respectively.

The knuckles formed on the surface of the upper side fabric by the upper side warps (1U to 8U) and the lower side binding yarns (4LB, 8LB) passing above the upper side wefts are oblique. not aligned in the same direction. Further, the knuckles formed on the surface of the upper surface side fabric include those having a displacement of one upper surface side weft and a displacement of two upper surface side wefts in the warp direction between adjacent upper surface side warps. The knuckles formed by the four aligned upper surface side warps are formed in different upper surface side wefts for each upper surface side warp.

The bottom side binding yarn 4LB passes over four continuous bottom side wefts (7'L, 8'L, 10'L, 11'L) in the weaving pattern of the 1/2-1/4 weave. In between, a knuckle N1 for knotting is formed through the upper side of the upper surface side weft 10'U. In addition, the lower surface side binding yarn 8LB similarly passes through the upper side of the continuous four lower surface side wefts (1'L, 2'L, 4'L, 5'L), and the upper surface side weft 4'U to form a knuckle N2 for connection.

The bottom side warps (1L to 8LB) pass under the same bottom side weft together with the bottom side warp adjacent to the left side to form a knuckle, and pass under the same bottom side weft together with the bottom side warp adjacent to the right side. and knuckles to be formed alternately.

A plurality of lower surface side binding yarns (4LB, 8LB) are arranged at equal intervals across three lower surface side warp yarns (1L to 3L, 5L to 7L) that are not binding yarns. The position where each of the two lower surface side binding yarns (4LB, 8LB) in the complete weave passes above the upper surface side wefts is the position where the six upper surface side wefts (4'U, 10'U) are displaced in the warp direction. be. In this way, the connection positions can be distributed and arranged. The bottom side wefts pass under the six continuous bottom side warps, exposing many of the bottom side wefts on the surface side of the bottom side fabric.

The wire diameter of the lower surface side weft may be set in the range of 1.5 to 2.5 times the wire diameter of the upper surface side weft. The lower surface side weft may be composed of a mixed weave of a wire made of polyethylene terephthalate resin and a wire made of polyamide resin.

Four of the eight upper surface side warps (1UB to 8U) function as upper surface side binding yarns (1UB, 3UB, 5UB, 7UB) that bind the upper surface side fabric and the lower surface side fabric. Four of the eight lower side warps (1LB to 8L) function as lower side binding yarns (1LB, 3LB, 5LB, 7LB) for binding the upper side fabric and the lower side fabric. The upper surface side binding yarn forms more knuckles on the upper surface side than the lower surface side binding yarn, and the lower surface side binding yarn forms more knuckles on the lower surface side than the upper surface side binding yarn.
