Description

  The woven fabric of the present invention is suitable as a bulky and marked nonwoven fabric or a woven fabric for paper production, and is excellent in fiber support, sheet peelability and the like, and has an uneven surface that can be used for high-speed machines. It relates to textiles.

Conventionally, fabrics woven with warps and wefts have been widely used as industrial fabrics that form uneven surfaces, such as wires for making nonwoven fabrics, papermaking wires, conveyor belts, and many other fields. Yes. It is used to impart marks and textures to paper, nonwoven fabric, etc. using unevenness, or to prevent slipping of conveyed items.
In particular, as a woven fabric for marking non-woven fabrics and paper, there are strict requirements such as fiber supportability, sheet peelability, and high-speed machine compatibility in addition to the height of the unevenness. In recent years, the demand has become more severe with the increase in the speed of nonwoven fabric manufacturing machines and papermaking machines.
There are various methods for marking fabrics. As disclosed in Japanese Patent Laid-Open No. 2005-9013, there is a method in which warp and weft floats (long crimps) are formed on the surface of a woven fabric so as to have a height difference in each region. In addition, as disclosed in Japanese Patent Application Laid-Open No. 2004-27407, a method of providing a mark due to a difference in the height of the knuckle top of the fine wire diameter warp and the thick wire diameter warp by arranging the thick wire diameter warp at some interval. There is. However, these are effective for imparting a geometric pattern or a spot-like pattern different from others, such as letters and streaks, but are not suitable for imparting bulk to a nonwoven fabric or the like due to the configuration of the entire fabric.
In addition, as a problem that is currently present, in the woven fabric for marking, there is a scattering of sheet raw materials due to an increase in machine speed. In wet papermaking, etc., fiber can be supplied together with a large amount of water, so a certain speed increase can be realized.However, in the case of dry papermaking, a very light fiber material is supplied on the fabric. May be scattered. This is especially true for fabrics with relatively flat surfaces. In order to solve this problem, scattering can be solved by using a woven fabric with a structure with severe unevenness, for example, but the fiber may sink under the component yarn and the sheet peelability may deteriorate. It was. As described above, the scattering of the fibers, the sheet peelability, and the unevenness imparting properties are contradictory problems.

About.

  The industrial fabric of the present invention has a structure in which 2 to 4 types of warp knuckles having different shapes based on a plain weave are arranged on the weft yarn at random on the surface on the upper surface side. It is excellent in high-speed machine compatibility and suitable for manufacturing bulky nonwoven fabrics.

  The woven fabric of the present invention can be suitably used especially in the field of production of nonwoven fabrics such as spunbond, meltblown, airlaid, spunlace, wet papermaking, dry papermaking, etc. By applying a concavo-convex pattern of a woven fabric in a drying process such as by the above, a bulky nonwoven fabric or paper having a concavo-convex pattern can be produced.

In the present invention, the lowermost weft in the design drawing is referred to as a first weft and the weft adjacent to the lower weft is referred to as a second weft in order to specify the position of the adjacent weft.
The fabric of the present invention is an industrial single-layer fabric composed of warps, wefts, and auxiliary wefts having a thinner wire diameter than the wefts. Basically, the weft is preferably a thick and rigid yarn, and a plurality of types of warp knuckles having different shapes are randomly formed on the relatively straight weft. Thus, in the woven fabric of the present invention, the top part of the warp knuckle is convex, the intersecting part of the warp yarns formed between adjacent wefts, and the auxiliary weft part on the intersecting part becomes the concave part, and the unevenness is caused by the height difference between them. It is formed. Moreover, since it is comprised by several warp knuckles from which a shape differs also in a convex part, it becomes a more complicated uneven | corrugated shape. The present invention forms a plurality of types of convex portions by the difference in height and the shape of the warp knuckle as described above, and does not form a pattern by adjusting the length of the warp and weft float. Basically, it is based on a plain weave. When the auxiliary weft is omitted, each warp and weft has a plain weave structure.
The plain weave structure of the warp and weft is a structure in which the structure passing through one weft and then passing under one weft is repeated, excluding the auxiliary weft. A structure in which one warp passes and then passes under one warp is repeated.

In the present invention, the warp knuckle refers to a convex portion formed along the shape of the weft thread through the top or the bottom of one weft thread, and one or a plurality of adjacent one weft threads. The convex part formed along the shape of the auxiliary weft of the book through or under is shown. Therefore, it is preferable that the warp yarn is of a wire diameter and a material that can easily bend and form a knuckle. For the height of the unevenness, the wire diameter and wire of each thread are very much involved.For example, if weft material is easy to bend, the weft will bend at the intersection of the warp and weft, and the height of the warp knuckle Becomes lower. Even if a rigid yarn is used as the weft, if the warp and weft have a thin wire diameter, the whole will be relatively flat. In addition, if the warp is made of a material that is difficult to bend, the fabric will have poor stability because the fabric does not intertwine in the vertical and horizontal directions.
The auxiliary weft is a configuration necessary for forming a plurality of types of warp knuckles having different shapes.
If the woven fabric has a plain weave structure in which no auxiliary weft is present, knuckles having the same shape are arranged and arranged, which is not suitable for manufacturing a paper or a nonwoven fabric having a ramdam mark. In the case of the woven fabric of the present invention, for example, the knuckle formed by passing the upper side in the order of the weft and the auxiliary weft and the knuckle formed by passing the upper side in the order of the auxiliary weft and the warp, for example, the shape and arrangement are It will be different. If the difference in the wire diameter between the auxiliary weft and the weft is small, the difference in the formed knuckle shape becomes small, so that a single type of convex portion is formed. This may be preferable, and it is necessary to examine the wire diameter balance and material of each yarn.
The arrangement ratio of the weft and the auxiliary weft may be 1: 1 in which one auxiliary weft is arranged with respect to one weft, the other 1: 2, or one after the two wefts. An arrangement of 2: 1 or the like with auxiliary wefts arranged may be used. In addition, one auxiliary weft after the one weft, then one weft, then two auxiliary wefts, or one weft. Next, one auxiliary weft, then two wefts, and then one auxiliary weft may be arranged.
As described above, the arrangement ratio and arrangement configuration of the weft and the auxiliary weft are not particularly limited, but a structure in which three or more wefts are continuously arranged is not preferable because it is difficult to form different knuckles. For this reason, it is preferable that at most two wefts are arranged continuously. Similarly, if three or more auxiliary wefts are arranged continuously, the knuckle shape variation is increased, but the warp and weft yarns are not entangled strongly and the knuckle stability is poor, which is not preferable. Therefore, it is preferable to have a structure in which at most two auxiliary wefts are arranged continuously.

And the warp knuckle forming the upper surface side surface is constituted by any one of the following first, second, third, fourth, fifth, and sixth types of knuckles, and the upper surface side surface is It shall consist of knuckles formed over the different numbers of wefts and auxiliary wefts.
The first knuckle is formed by passing through a total of two wefts, one weft and one auxiliary weft arranged adjacent to each other on the fabric structure. The second knuckle is arranged adjacent on the fabric structure. The third knuckle is formed by passing one auxiliary weft and two auxiliary wefts adjacent to each other on the fabric structure. The four knuckles were formed in order through a total of three auxiliary wefts and one weft arranged adjacent to each other on the fabric structure. The fifth knuckle is formed by passing through a total of three auxiliary wefts, one weft and one auxiliary weft arranged adjacent to each other on the fabric structure. The knuckle is formed through the upper side of one weft.
Here, the knuckle formed on the wefts and the auxiliary wefts having different total numbers means that the first and second knuckles are formed on the total two of one weft and one auxiliary weft. The third, fourth, and fifth knuckles are knuckles formed over a total of three, one weft and two auxiliary wefts, and the sixth knuckle is one total of one weft. Since the knuckle is formed over the top surface, a combination of a knuckle formed over a total of two top surface surfaces and a knuckle formed over a total of three top surfaces, or a top surface A combination of a knuckle formed on a side surface over a total of one and a knuckle formed over a total of three or a top surface formed over a total of one. Knuckles and knuckles formed over 2 total, 3 total A combination of knuckles formed over the top, a knuckle formed over the top surface and a total of three knuckles formed over a total of two knuckles There are combinations of three types of knuckles formed through the top. And since the 1st knuckle and the 2nd knuckle are knuckles formed over two in total, the combination of only these knuckles formed over the same number shall not be included in the present invention. Similarly, since the third knuckle, the fourth knuckle and the fifth knuckle are knuckles formed over a total of three, the combination of only these knuckles formed over the same number is included in the present invention. Suppose there is nothing. However, a combination of four types of knuckles, the first and second knuckles formed over a total of two and the third and fourth knuckles formed over a total of three, etc., at least It does not matter as long as two or more types of knuckles having different lengths exist on the upper surface side surface.

As a specific upper side structure of the present invention, the upper side surface has a total of two warp knuckles in which the warp passes over one adjacent weft and one auxiliary weft, and a weft with one warp. In the case of being constituted by two types of warp knuckles passing over, there are those constituted by two types of knuckles, either a first knuckle or a second knuckle and a sixth knuckle.
Then, the upper side surface has a total of two warp knuckles that pass over one weft and one auxiliary weft adjacent to the warp, and one weft and two auxiliary wefts adjacent to the warp. When the upper surface side surface is constituted by either the first knuckle or the second knuckle and either the third knuckle, the fourth knuckle or the fifth knuckle. Some are composed of two types of knuckles.
The upper surface has a warp knuckle where the warp passes over one weft, a total of two warp knuckles where the warp passes over one adjacent weft and one auxiliary weft, and the warp In the case of three types of warp knuckles for a total of three passing over one adjacent weft and two auxiliary wefts, the upper surface side surface is either the first knuckle or the second knuckle, There is one constituted by three types of knuckles, either a three knuckle, a fourth knuckle or a fifth knuckle, and a sixth knuckle. In addition, one or two types of the first knuckle or the second knuckle, and any two or one type of the third knuckle, the fourth knuckle or the fifth knuckle are constituted by a total of three types of knuckles. There is also.

In addition, if the upper surface is composed of knuckles formed over the wefts and auxiliary wefts having different total numbers, the upper surface is the first knuckle, the second knuckle, or the third knuckle. Alternatively, any one of the four knuckles or the fifth knuckle and a total of three knuckles of the sixth knuckle may be used. Alternatively, it may be constituted by any four types of knuckles of the second knuckle, the third knuckle, the fourth knuckle, the fifth knuckle or the sixth knuckle. There are various combinations of these, but it is sufficient that at least the warp structure and the warp structure excluding the auxiliary weft form a plain weave structure, and the structure may be appropriately determined according to the purpose and method of use.
In the present invention, the first knuckle and the second knuckle, and the third knuckle, the fourth knuckle and the fifth knuckle are different only in the arrangement position of the auxiliary weft arranged adjacent to the weft, but each knuckle shape is also different. Is. In this manner, two to four types of warp knuckles having different shapes are formed on a straight weft, and a plurality of types of protrusions having different shapes in the width direction are formed. In addition, the knuckle is arranged in the front including the weft, the rear including the weft, or the middle, so that the knuckles are not arranged in a straight line, and the surface is randomly uneven in shape and arrangement.
Further, there is no limitation as to which warp forms which knuckle. For example, a structure in which one warp forms only the first knuckle and the other one warp forms only the third knuckle. Alternatively, a structure in which one warp forms the fifth and sixth knuckles and the other warp forms only the second knuckle may be used. What is necessary is just to be comprised from the knuckle formed on the upper surface side surface through the weft and auxiliary weft from which the total number differs.

There is no particular limitation on the structure of the auxiliary weft, but it is not preferable to use a structure that passes over many continuous warps. Although there is an effect of improving the fiber supportability by arranging the auxiliary wefts between the wefts, the present invention forms warp knuckles having different shapes on the surface on the upper surface side, so that if the auxiliary wefts float too long When the structure is limited and used as a woven fabric for manufacturing a nonwoven fabric, it is necessary to consider them because fibers as a nonwoven fabric material may sink under a long auxiliary weft and reduce sheet peelability. Preferably, the structure passes above and below one warp, or the structure passes above two continuous warps and below two warps. Although the structure of the auxiliary weft may be one type or more, it is preferable that the entire woven fabric has one or two types of structures. It is not preferable to arrange too many types of structures because of problems of weaving properties and tension balance of the fabric.
The weft structure is a structure in which an upper side and a lower side of one warp are alternately passed to form a plain weave structure on the upper surface side and the lower surface side. In the warp structure, the structure from which the auxiliary weft is removed is a structure that forms a plain weave structure. The woven fabric of the present invention forms a complex uneven surface due to the top part of the warp knuckle and the intersecting part of the warps formed between the adjacent wefts, the height difference of the recesses due to the auxiliary wefts, and the difference in the shape of the warp knuckle. The pattern is not formed by the length of the float of warp and weft, and is basically based on plain weave.
In the case of the plain weave structure referred to in the weft of the present invention, since the weft is woven by a rigid and difficult to bend and a warp which is easy to form a knuckle, the weft does not protrude on the upper surface side and the lower surface side. Since the weft yarns pass through one warp and the lower one in sequence, it can be said that the structure is a plain weave.

  Although the lower surface is not particularly limited, since the warp is a structure that forms a plain weave when the auxiliary weft is removed, a warp knuckle that passes under one weft on the lower surface or one continuous thread And a warp knuckle passing under one to four auxiliary wefts. The configuration of the lower surface side knuckle formed by the warp on the lower surface side is always one weft, but the number of auxiliary wefts combined therewith is 0, 1, 2, 3 or 4 at maximum. Good. For example, a lower side knuckle that passes through one weft, an adjacent one weft, a lower side knuckle that passes through a total of two lower sides of one auxiliary weft, an adjacent auxiliary weft, one Lower side knuckles that sequentially pass through a total of three lower sides of one weft, a lower side knuckle that sequentially passes a total of three lower sides of two adjacent auxiliary wefts and one weft, It may be a lower side knuckle that sequentially passes through a total of five lower sides of two adjacent auxiliary wefts, one weft, and two auxiliary wefts. The lower surface is not limited which warp forms which knuckle. For example, a lower surface knuckle in which one warp passes under one auxiliary yarn and two auxiliary wefts on the lower surface, It may be a structure that forms two knuckles of the lower surface side knuckle passing under one weft, and the warps constituting the woven fabric may be the same structure or different structures. The lower surface may be any surface as long as the warp is composed of one weft, or one lower weft and adjacent lower wefts and one to four auxiliary wefts. What is necessary is just to select suitably from the relationship of a side surface structure | tissue.

The yarn used in the present invention may be selected depending on the application. For example, in addition to monofilament, multifilament, spun yarn, crimped processing, bulky processing, etc., generally textured yarn, bulky yarn, stretch yarn, etc. Processed yarns that are called, or yarns that are combined by twisting them can be used. The material of the yarn can also be freely selected, and polyester, polyamide, polyphenylene sulfide, polyvinylidene fluoride, polypro, aramid, polyetheretherketone, polyethylene naphthalate, polytetrafluoroethylene, cotton, wool, metal, etc. are used. it can. Of course, you may use the thread | yarn which blended and contained various substances according to the objective to these copolymers or these materials. Further, in particular, as a woven fabric for manufacturing a nonwoven fabric, a conductive yarn may be used as a part of the woven yarn in order to prevent generation of static electricity. I do not care.
Polyphenylene sulfide and the like are preferable in a high temperature atmosphere, and polyester and polyamide are generally used as industrial fabrics. In particular, the weft constituting the woven fabric of the present invention is preferably a rigid and difficult-to-bend yarn. Therefore, monofilaments, converging yarns in which monofilaments are bundled, twisted yarns and the like are suitable, and those having a relatively large wire diameter are preferred. In the warp, those having a diameter and material that are easy to bend along the shape of the weft and the auxiliary weft to form a knuckle are preferable, and monofilaments, converging yarns in which monofilaments are bundled, twisted yarns, and the like are suitable. Those having a smaller wire diameter are preferable. As auxiliary wefts, monofilaments, multifilaments, twisted yarns, decorative yarns, hollow yarns, etc. are suitable, and they are also used for tension adjustment of warps with large bends in the weaving stage of fabrics. Rather, a flexible yarn is preferred.
In addition, flat yarns are sometimes used for non-woven fabric production purposes for purposes such as resistance to dirt, ease of cleaning, and making smooth joints when joining endlessly. In both the weft and the auxiliary weft, not only a circular cross section but also a short thread such as a quadrangle and a star, and a flat, elliptical and hollow thread can be used. Of course, they may be used in combination. For example, the warp yarn may be a flat cross-sectional yarn, the weft yarn and the auxiliary weft yarn may be a circular cross-sectional yarn, and some of the flat warp yarns may be circular warps. For example, in a high-speed machine for manufacturing nonwoven fabrics, if the surface of the fabric is too smooth, the fiber sheet formed on the fabric may be scattered. Therefore, for the purpose of providing a structure in which fibers are pierced into the woven fabric to some extent, we may weave as a circular warp in which a part of two flat warps are aligned. Such a woven fabric has an effect that the fibers are appropriately inserted and scattering of the sheet is suppressed. However, if too many circular warp yarns are arranged, the fibers may be stuck too much and the sheet peelability may be deteriorated.
Also, within this specification the upper side surface so as to facilitate explanation, has been described as the lower surface side surface, the raw material contact surface either for a single layer fabrics, may be used as the machine contact surface.

The invention will be described on the basis of embodiments with reference to the drawings.
1-32 is an Example of this invention, Comprising: It is either a design drawing, sectional drawing along warp, or sectional drawing along weft. The design drawing is the smallest repeating unit of the fabric structure, and this complete structure is connected vertically and horizontally to form the entire fabric structure. In the design drawing, warps and wefts are indicated by Arabic numerals, for example, 1, 2, and 3, and auxiliary wefts are indicated by Arabic numerals with dashes, for example, 1 ′, 2 ′, and 3 ′.
In addition, the x mark indicates that the warp is located above the weft, and the portion where the warp knuckle is formed by passing the warp over the weft and the auxiliary weft is shaded.
In the design drawing and the cross-sectional view, the weft and the auxiliary weft are arranged at equal intervals, but they may be arranged so as to be shifted due to the structure.

Example 1
FIG. 1 is a design diagram of a fabric of Example 1 of the present invention. FIG. 2 is a sectional view taken along warps 1, 2, 3, and 4 of the design diagram of FIG. FIG. 3 is a sectional view taken along the weft 1 and the auxiliary weft 2 'of the design diagram of FIG. FIG. 4 is a cross-sectional view of the warp where the adjacent warps 1 and 2, 2 and 3, 3 and 4, 4 and 1 intersect. One weft and one auxiliary weft are alternately arranged at a ratio of 1: 1. The symbols A to D on the design drawing represent the positions of the recesses A to D.
The weft yarn is a rigid yarn that has a relatively large wire diameter and is difficult to bend. On the other hand, the warp yarn and the auxiliary weft yarn are bent to easily form a knuckle. Therefore, as can be seen from the cross-sectional view along the weft 1 in FIG. 3, a relatively straight knuckle is formed on both the upper surface side and the lower surface side of the weft.
As shown in FIGS. 1 and 2, the upper surface side surface is formed by two warp knuckles having different lengths. For example, there is a structure that forms a second knuckle passing through the adjacent auxiliary weft and the upper side of the weft in order, and a sixth knuckle passing through the upper side of one weft. In all four warps 1 to 4, the structure forms the second knuckle and the sixth knuckle.
As can be seen from the weft 1 in FIG. 3, the weft is a plain weave structure that passes alternately above and below the warps 1, 2, 3, 4, and similarly, the warp also excludes the auxiliary weft from the warp cross section. This is a plain weave structure that alternately passes above and below the wefts 1, 3, 5, and 7. The structures of the auxiliary wefts are all the same structure and pass under one warp and under one warp above three warps.
The lower surface is composed of one auxiliary weft with a continuous warp and a lower knuckle passing under one weft, one auxiliary weft, one weft, one auxiliary weft under It is formed by the lower surface side knuckle which passes through.

Moreover, the unevenness | corrugation of this textile fabric is demonstrated with reference to FIG. 4 which showed sectional drawing of the adjacent warp. As shown in the design drawing, the warps are arranged at almost equal intervals in the order of warps 1, 2, 3, and 4. In the warps 1 and 2, the warp 1 passes over the auxiliary weft 2 'and the weft 3 to form a second knuckle on the upper surface, and then passes under the auxiliary weft 4', the weft 5, and the auxiliary weft 6 '. Next, a sixth knuckle is formed on the weft 7, and then the structure passes under the auxiliary weft 8 ′ and the weft 1. The warp 2 passes over the auxiliary weft 8 'and the weft 1 to form a second knuckle on the upper surface, then passes under the auxiliary weft 2', the weft 3 and the auxiliary weft 4 ', and then on the weft 5. A sixth knuckle is formed on the surface on the upper surface side, and then the structure passes under the auxiliary weft yarn 6 ′ and the weft yarn 7. As a result, in the warp 1 and the warp 2, the second, second, sixth, second, in order, on the auxiliary weft 8 'and the weft 1, on the auxiliary weft 2' and the weft 3, on the weft 5, and on the weft 7. Six knuckles are formed, and these knuckles become convex portions. Then, the warp 1 and the warp 2 intersect to form recesses A, B, C, and D between the wefts.
Concave portion A is where warp 1 falls from above auxiliary weft yarn 2 'to below weft yarn 1 and where warp yarn 2 falls from above weft yarn 1 to below auxiliary weft yarn 2'. Is the place where the warp 1 falls from the top of the weft 3 below the auxiliary weft 4 'and the place where the warp 2 falls from the top of the weft 5 to below the auxiliary weft 4'. The place where the warp 1 falls from the top of the weft 7 to below the auxiliary weft 6 'and the place where the warp 2 falls from the top of the weft 5 to below the auxiliary weft 6' is the most depressed. Is the place where the warp 2 falls from the top of the weft 7 to the bottom of the auxiliary weft 8 'and the place where the warp 2 falls from the top of the auxiliary weft 8' to the bottom of the weft 7. There is a difference in height from the top of the knuckle It will be closed.
Between the warp yarns 2 and 3, the warp yarn 2 passes over the auxiliary weft yarn 8 'and the weft yarn 1 to form a second knuckle on the upper surface, and then the auxiliary weft yarn 2', the weft yarn 3, and the auxiliary weft yarn 4 ' A sixth knuckle is formed below the weft 5 and then passes through the auxiliary weft 6 ′ and the weft 7. The warp 3 passes under the auxiliary weft 8 ', the weft 1, and the auxiliary weft 2', then passes over the weft 3 to form a sixth knuckle on the upper surface, and then the auxiliary weft 4 'and the weft 5 The structure passes through the bottom, then passes over the auxiliary weft 6 'and the weft 7, and forms a second knuckle on the upper surface. As a result, in the warp 2 and the warp 3, the second, sixth, sixth, and second in order on the auxiliary weft 8 'and the weft 1, on the weft 3, on the weft 5, and on the auxiliary weft 6' and the weft 7, respectively. Two knuckles are formed, and these knuckles become convex portions. Then, the warp 2 and the warp 3 intersect to form recesses A, B, C, and D between the wefts.

Between the warps 3 and 4, the warp 3 passes under the auxiliary weft 8 ', the weft 1, and the auxiliary weft 2', and then passes over the weft 3 to form a sixth knuckle on the upper surface. Next, it passes under the auxiliary weft 4 ′ and the weft 5, and then passes over the auxiliary weft 6 ′ and the weft 7 to form a second knuckle on the upper surface. After the warp 4 passes over the weft 1 and forms a sixth knuckle on the upper surface, it passes under the auxiliary weft 2 'and the weft 3, and then the second knuckle is placed on the auxiliary weft 4' and the weft 5. Then, the structure passes through the auxiliary weft 6 ', the weft 7, and the auxiliary weft 8'.
