201223492 6. DISCLOSURE OF THE INVENTION: TECHNICAL FIELD The present invention relates to a nonwoven fabric, a method of manufacturing the same, and a wiping material. [Prior Art] In order to impart various functions to the nonwoven fabric, a nonwoven fabric for imparting woven or the like to the application has been proposed. The patent document 丨 discloses a non-woven fabric which is used, for example, in a bandage or the like and has a plurality of openings formed on almost the entire surface. In this case, a plurality of openings are formed in the openings, and openings having various sizes and/or shapes are mixed so that body fluids and the like are not easily passed. Patent Document 2 describes a wiping material in which a straight line and a straight line or a curved line are combined. Patent Document 3 discloses, for example, a non-woven fabric which is improved in function as a wiping material. In this non-woven fabric, there are alternately arranged open-cell rows and non-opened rows in which the through holes are continuously connected. Patent Document 4 describes a wiping material in which a portion having a low interlacing density and a higher portion are formed by hydroentanglement and a low interlacing portion is surrounded by a high interlacing portion. Patent Document 1: Japanese Unexamined Patent Publication No. Hei No. Hei. No. Hei. No. Hei. Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. 2, No. 1 873. [Patent Document] However, in Patent Document 1, V χ , , , 屺 , , , , , , 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 2012 Because there will be streaks caused by pollution, there is a need for improvement. Since the non-woven fabrics described in Patent Document 2 are formed by forming a slanted straight line or a curved portion by heat compression, the fibers are bonded to each other, so that the wiping property is required to be improved. The non-woven fabric described in Patent Document 3, when used as a wiping material, exhibits good rubbing properties when wiped in a direction orthogonal to the longitudinal direction of the row of holes, but does not exceed the length direction of the row of the openings or the oblique direction thereof. When wiping in the direction of 45 degrees, there are stains caused by dirt, so there is a need for improvement. In the wiping material described in Patent Document 4, in order to form a portion having a high interlacing density, it is necessary to move a nozzle tip having a high weight, resulting in an increase in the cost of the apparatus. Therefore, there is a demand for improvement. Further, although the portion having a high interlacing density (high interlaced portion) is formed by hydroentanglement, the high interlaced portion is only a nozzle streaks formed by a water flow, and is required to be improved in terms of functionality and shape. ^ j To solve the above problems, the present invention provides a wiping month & a non-woven fabric, a manufacturing method thereof, and a rubbing material. The nonwoven fabric of the present invention is a nonwoven fabric comprising a fiber assembly, the nonwoven fabric (4) 1 interlaced portion and a second interlaced portion; the second interlaced portion has a regular weave formed by hydroentangling the constituent fibers of the specific portion of the nonwoven fabric The first interlaced portion and the second interlaced portion are separated from each other and have a plurality of columns; at least one of the first interlaced portion and the second interlaced portion maintains a width of 2 mm or more along the direction of the non-woven fabric. Hey. The rubbing material of the present invention contains the aforementioned non-woven fabric. In the method for producing a non-woven fabric of the present invention, the portion of the constituent fibers of the fiber assembly is hydroentangled on a specific support having a regular weave, whereby a part of the constituent fibers is rearranged to obtain a丄F is formed so that the second interlaced portion having the regular woven in the plural column and the first interlaced portion in which the second interlaced portion is separated from each other are formed, and the first interlaced portion is formed. a. When the hydrofoil of the parent 2 is entangled, the pressurized water flow is ejected through the aperture member to the x-ray fabric, and the aperture member is vibrated, whereby the first interlace portion and the second interlace are woven. At least one of the ministries is formed. The non-woven fabric has a high wiping performance because the first interlaced portion and the second interlaced portion having the regular weave are separated from each other and have a plurality of rows. Further, at least one of the 交织i interlaced portion and the second interlaced portion has a high shape as a non-woven fabric by maintaining a width of two or more and spaced along the woven fabric. ° Further, the wiping of the present invention provides a wiping material with high wiping performance even in any wiping property in the longitudinal, transverse and oblique directions. The manufacturing method of the woven fabric is such that the opening member vibrates and the following: The 丨 interlace and/or the second cross are close to the woven woven line. In the present invention, the fiber assembly can be re-arranged only, and the mesh, the bonded mesh, the knitted fabric, or the net shape re-arranged by the hydroentanglement is not particularly limited. Fiber can be wrapped by water. For example, a fiber web or an interlaced laminated body β fiber web may be used, and it is not particularly limited. For example, 5 201223492 lists a card web, an ajr web, and a wet paper net. , long fiber webs (such as spunb〇nd web), and meltblown web. Interlaced mesh refers to the interlacing of fiber webs, especially the state of the fiber web, and the interlacing of the fiber web, for example, from the viewpoint of productivity, by needle punching, hydroentanglement, water vapor flow It is carried out by any method such as the steam jet interlacing method. However, since the formation of the second interlaced portion is performed by hydroentanglement, it is preferably carried out by a hydroentangling method. The bonding network refers to a combination of a fiber assembly, particularly a constituent fiber of a fiber web, with respect to one another. For the bonding method, for example, an embossing process, an air thr〇ugh method, and a chemical bonding can be cited. Chemical bond, etc. The nonwoven fabric of the present invention contains a fiber assembly as a main component. The main component of this dollar is a component having a content of ~(10)% by mass relative to the overall mass of the non-woven fabric. In the fiber assembly, any of the fibers may be used as long as it is used as a general net (an assembly in which a plurality of fibers are arranged). For example, you can use recycled fiber represented by cotton, hemp, wool, and wood (4) P) as the representative of the natural fiber = 嫘萦 (four) on), with acetic acid from the purpose (Caf = representative of semi-synthetic fiber, to poly The purpose, polyolefin (4). 丨 ah, financial theory, and acrylic (acrylic) are representative of the fiber length of the fiber compared to Μ 5 麟 ° ° °, and in the fiber assembly ~ 7. Follow. If the fiber length is not up to Λ. More preferably, the length of the fiber is 25-dimensionally longer than one or two, and the strength of the non-woven fabric is weakened. For the shape of the non-woven fabric of the present invention, the constituent fibers of the fiber assembly are limited, and for example, a single fiber or sheath can be cited. Core type 201223492 Composite fiber, split type composite fiber, or fiber having a modified cross section. Examples of the modified cross section include a polygonal type of a Y type, a type, a triangle, a star shape, and a cross type. The flat profile, the multi-leaf type, etc. Further, the profile of the modified profile may have a roundness. If the fiber of the modified profile is included, the wiping property of the nonwoven fabric is improved. The constituent fiber system contains scorpion species or two or more species In the case of at least one of the two or more kinds of materials, if a material having a relatively low melting point compared with other materials is contained, the woven fabric can be satisfactorily maintained while the constituent fibers are fused to each other. In the case where the constituent fibers are composed of two or more kinds of materials, the fiber assembly is composed of one type of constituent fibers, and the constituent fibers themselves are composed of two or more materials, and the fiber aggregates are different in material. In the case of the above-mentioned constituent fibers, the same is true. The fineness of the constituent fibers is based on good hydroentangleability and does not adversely affect the fibers, and can be formed into a distinct (four) reason, preferably 〇ι~ 6.6dtex' is more preferably 0.25 to 3 3 (1). The use of the non-woven fabric of the present invention as a wiping material is appropriately set, and the type or fineness of the fiber to be used and the amount of the non-woven fabric are appropriately set. For example, ^ 〇 ^ For example, the non-woven fabric of the present invention is used as a dry mop such as a mop or a precision rag for the purpose of wiping fine dust, garbage, and the like. In the case of a material, or a wet tissue (wet b "ssue", a sweat-proof towel, or a detachable wiping material, the non-woven fabric is preferably made of a non-coherent 2 忐 furnace and contains at least 纤维 in the fiber cross section. The octagonal knives are cut into two bismuths, and the split type conjugate fiber is 5% by mass or more. The better is 3 〇% by mass on 201223492.乙妇-二 can be cited as a combination of nylon and polyester, polyester 〇埽-vinyl alcohol copolymer and ethylene, etc. The 纤, olefin, and the fineness of the polyester and the polyfiber are very private. Less reasons _ : 艮 good wiping, residual liquid U seeking reasons, and based on good water weaving trend and other reasons, compared to ', 丨, there are easy to appear into the 丨 soil sentence j_3dtex below. In addition to the knife-cut type composite fiber, a fiber containing 6.6 dtex or less of the fibers contained in the woven fabric may be cited, and the t is preferably a fiber or a fiber of the fiber. . Among the constituent fibers of the non-woven fabric, the heat-fusible fiber to be welded is preferably a heat-resistant nonwoven fabric. Also, it can be lifted = stretched to reduce the growth caused by the use of the skin. This kind of looseness is therefore suitable for rags (non-woven, because it is not easy to be 1 per). Therefore, if the non-woven fabric of the present invention constituting the fiber-bonded ancient phase fusion fiber is used, the hood is wiped out and the helmet is easy to wipe. A rag that can be gently wiped by applying force. Such a non-woven fabric can be heat-treated by the heat treatment of the fiber web after the step of causing the second interlaced portion of the woven fabric having a specific rule to impart at least a portion of the constituent fibers. In the constituent fibers of the nonwoven fabric, the hydrophilic fibers may be contained in an amount of more than 30% by mass. More preferably, it is 30% by mass or more. If it contains a water-based fiber, The affinity with water is high and the wiping efficiency can be improved. Further, if the right side contains hydrophilic fibers in the above range, the interlacing property of the fibers at the time of hydroentanglement is better, and the formation of regular woven fabrics becomes better. The non-woven fabric of the invention may be provided in a laminated structure of two or more layers. 201223492 For example, in the case where the layer mainly contains a hydrophilic fiber, if it is provided with a (four) liquid or the like, it is excellent. A wiping squeegee, such as a wet wiper, a wet wipe, or a disposable wet wipe, etc. In particular, the non-woven fabric is provided with a laminated structure of A 3 or more layers. Further, when a layer mainly containing a hydrophilic fiber such as hibiscus is used as the intermediate layer, since the layer mainly containing the hydrophilic fiber serves as the liquid retaining layer, the liquid can be gradually sent out to the surface, which is preferable. In the case where a layer mainly containing a hydrophilic fiber such as a wooden beam is used as the intermediate layer, it is preferable that the regular weaving obtained by the hydroentangling treatment can be made apparent. Here, "mainly" means mainly containing hydrophilicity. The layer of the fibrous fiber contains 5% by mass or more of the hydrophilic fiber as a main component. The nonwoven fabric of the present invention has a 帛1 interlaced portion and a second interlaced portion, and the i-th woven portion and the second interlaced portion are separated from each other and have a plurality of rows. In the present invention, the first interlaced portion and the second interlaced portion are separated from each other and the plural interlaced portion is present, and the first interlaced portion and the second interlaced portion are independently formed, and a plurality of (four) U-woven portions and a second interlaced portion are formed, that is, There are a plurality of interlaced portions in which a plurality of independent existences are formed. As will be described later, the second interlaced portion is formed by hydroentangling the constituent fibers of the specific portion of the fiber assembly. On the other hand, the 1 i intersection portion may be in the state of the fiber web, the state of the bonded mesh, and the state of the interlaced mesh. The state of any of the above-mentioned fiber aggregates is not particularly limited, but the mesh is compared with the mesh. The interlacing property is preferred, so that the shape of the interlaced portion of the crucible 2 is better, or the interlacing property of the fiber is stronger than that of the fiber web, so that the fluff of the fiber can be suppressed. The elbows form the fibers and are woven by each other to form the father. In addition, although the fiber interlacing can be performed by the pinning method or the hydraulic entanglement method, 201223492 'But the second interlacing is preferably a method of forming the part by a method such as hydroentangling water vapor Ll·interlacing method. It is carried out by hydraulic entanglement, so the law proceeds. In the interlaced portion of the younger brother, the constituent fibers are interlaced by the water jet (hereinafter also referred to as WJ) on the entire surface of the fiber web containing the front fibers. The WJ process is carried out by placing a fiber web on a conveyor support and spraying a stream of water on one or both sides of the screen. At this time, the constituent fibers are interlaced with each other, and the net is integrated to obtain a non-woven fabric. The water treatment conditions can be appropriately set depending on the amount of coating of the fiber web and the speed of the conveyance support. For example, 'the nozzles are provided with holes #. 〇〇5~ :5_ at the interval of 0·2~, and the nozzles are sprayed four times from the front and back sides of the fiber web. The water flow of pa can be. More preferably, it is a water pressure. If the water pressure is less than 1 Mpa, the fibers are not interwoven with each other, and the obtained non-woven fabric is liable to cause fluff falling off. If the water pressure exceeds 2_/, the fibers are interlaced with each other too much, and the degree of freedom of the fibers is lowered to cause _hardening or the texture of the nonwoven fabric is deteriorated. Thereby, the portion where the constituent fibers are interlaced (the portion which becomes the second interlaced portion later = minute) is referred to as the i-th interlaced portion. Further, the ith interlaced portion may be subjected to an operation of thermally fusing the constituent fibers by heat treatment, as long as it is effective. * The progress is to make the constituent fibers of the specific portion of the non-woven fabric hydraulically entangled as the second interlaced portion. Preferably, the second interlaced portion has a regular weave by the WJ. The rule woven means that the constituent unit of the constituting 10 201223492 is, for example, a woven fabric composed of at least one selected from the group consisting of irregularities and openings, or a woven fabric made of pUin. Specifically, a point (circle, ellipse, triangle, polygon, etc.) woven, Yamagata twill weave, checkerboard woven, woven woven, staggered woven, and sawtooth woven, etc. The weave is preferably different from the weaving of the second interlaced portion. In the case where the second interlaced portion and the second interlaced portion are the same woven, a difference in thickness is imparted, that is, a difference in unevenness is imparted. For example, when the second interlaced portion is a concave portion, the 帛1 interlaced portion is provided. When the second interlaced portion is a convex portion, the first interlaced portion is a concave portion, and two kinds of interlaced portions that can be clearly distinguished can be formed, whereby the wiping property is improved even if the wiping property is good. It is larger dust and easy to pick. When the unevenness of the thickness is applied to the first interlaced portion and the second interlaced portion, the thickness difference (concavity difference) is preferably 〇1〇 to 3 〇〇mm^, more preferably 0.20 to 2.00 mm, further preferably 〇30—〇〇_. Further, the thickness ratio (concave-convex ratio) is preferably 1.03 to 2.00, more preferably 1.05 to 1.70, still more preferably Μ, and the difference between the density of the second interlaced portion and the entangled portion can be made clear. There are two types of interlaced parts in the area, so that the wiping property becomes good, and even large dust is easy to pick. When the density difference is given between the second interlaced portion and the second interlaced portion, the density difference is preferably G.GG5 to G.15g/em3, more preferably G.GG8 to G.12g/em3, and further step-by-step. Good is 0.010~〇1〇g/cm3. Also, the density is preferably ι〇5~3·〇〇 ‘more preferably ι.10~2 〇〇, further preferably 丨15~丨5〇. In the same manner as the second interlaced portion, it is preferable that the first interlaced portion has a woven shuttle which is different from the woven fabric of the second interlaced portion. When the first interlace is a regular weave different from the weaving of the second interlaced portion, it is preferable to obtain various functions and effects of various kinds of regular woven fabrics of 201223492. Each rule woven system has various functions or effects. For example, a point woven or the like in which an opening is formed at a specific interval contributes to the improvement of the scraping property, and when it comes into contact with the skin, the contact area becomes small, so that it is difficult to attach the skin. In the mountain-shaped twill weaving, the water absorption of the nonwoven fabric is improved by repeating the relatively high density of the fiber and the lower portion in a small cycle, thereby facilitating the formation of a capillary phenomenon or the like. χ, the shape of the mountain-shaped oblique bite woven fabric due to the relatively high density of the fiber and the lower part of the original is: good. In the case of plain weave, for example, when used as a wiping material, it is preferable because it can cleanly wipe (4) the stain caused by the stain remaining when it is dirty. Therefore, if a plurality of woven fabrics are provided, a non-woven fabric having a plurality of functions can be provided. As far as the method of forming such a rule weaving is concerned, it is only necessary to use a support having such a rule weaving. The form of the support is not particularly limited to a pattern net formed by using a monofilament or a braided metal wire arbitrarily, or a roll having a projection (r〇u) is widely used. user. Specific examples thereof include a plain weave, a mountain-shaped twill weave, a twill weave, a spiral weave such as a pattern net or an open plate plate, and an aperture roll. In the case where the regular woven is an open woven, the area of one opening (hereinafter, only referred to as the opening area) is preferably 〇.丨~6.〇mm2, more preferably 〇3~5 _ 5 Mm2. Further, the distance between the centers of the apertures closest to each other (hereinafter, also referred to as the aperture distance only) is preferably 1.0 to 3. 〇mm, more preferably 15 to 12 201223492

It can be measured using a stereo microscope. The distance between the middle and the middle, as in the preferred composition of the non-woven fabric of the present invention, the arranging of the interlacing portion is a plain weave, and the other is a door opening: 4 Ρ and the second, for example, if the sixth city side It is the composition of the opening woven. The parent weave is plain weave, and the second cross is made by the opening weaving, ^ # scraping off the dirt with the first weaving, and then wiping it with the weave, and avoiding the scraping of the weave Except for the second: the first is not good, the piano is a non-woven fabric of plain weave, and the non-woven fabric with the woven surface is woven, but it is excellent in autumn, but it cannot be cleanly caught, and it is excellent. Smudges. The woven fabric of the woven fabric is woven by the woven fabric, and the woven fabric is woven by the woven fabric, and the woven fabric is arranged in a straight line, but the strips and the length of the strip are crossed. In the direction of the length of the stripe or in the direction of 45 degrees obliquely, ▲ will leave a wiping streak due to dirt. The ith interlaced portion and the second woven portion are preferably in a direction that is not in the direction of the non-woven fabric, and is preferably in any direction because the rubbing marks formed by the stain do not remain in any direction. Interwoven. The 交织 and the second interlaced portions are separated from each other and there are a plurality of woven fabrics having at least two different functions or effects, and the woven fabric having a woven fabric having a woven fabric is more The non-woven fabric of the nature is also more excellent in wiping properties when used as a wiping material. In the non-woven fabric of the present invention, the first interlaced portion and/or the second interlaced portion are spaced along one of the non-woven fabrics at intervals of a width of 2 mm or more. Further, 13 201223492 The non-woven fabric of the present invention is spaced apart and the weight of the second parent fabric is 2 mm or more. The second interlaced portion: wide cloth: ~ 蜒, more preferably woven portion and direction 婉蜒. Further, the second non-woven fabric refers to the length in the direction orthogonal to the width of the non-woven fabric and the width, the second portion, and/or the second six-fourth portion of the second interlaced portion. Further, the first interlacing and the parent weaving portion may be discontinuous and on the way +, the third interlaced portion is also the same, and the third intersection =: 'broken. This is described later. In Chiang ^ < ”. Also discontinued and interrupted on the way to use the non-woven fabric as the preferred range of width 3~2〇〇m, brother 1 1 interlaced part of your $20〇mm, better range Into the two range is 3~5. _, the special range is: ~3〇_2 3^, 〇〇1 ^ ^ ® #'3 — .,i Λ 〜3〇m 'better range 3~ The optimum range of 5〇mm' is 5, even if it is wiped in any direction of vertical, horizontal or oblique direction, it can be seen with excellent wiping performance, and it can provide high j, „ <non-woven and rubbed coffin. Further, in this way, the second interlaced portion and the second parent weaving portion are along the direction of the non-woven fabric, and the second interlaced portion is not along the direction of the first interlaced portion and/or the second interlaced portion. A non-woven fabric which is stronger in strength than a non-woven fabric which exists in a straight line shape. In particular, the non-woven fabric of the present invention is higher along the 婉蜒 [10% extension stress in the ** direction]. In the case where the i-th interlaced portion is plain: 夂: the width of the i-th interlaced portion is preferably 2 to 10 mm. If the width of the plain weave is too large, the scraping property of the stain will be ambiguous, and the wiping performance of the right is worse: the situation. Further, the ratio of the width of the first interlaced portion in the non-woven fabric s in the first interlaced portion is the ratio of the width of the flute 1 and the ang 2 interlaced portion (the first interlaced portion/the second interlaced portion) , better ^ two 0.1 ~ 4 'better 201223492 =. 3 ~ 3, further better for q5 ~ 2_. In the first case, and -!1, there will be residual residue of the rubbing marks. If more than 4, the scraping property of the stain will be deteriorated, resulting in wiping and not being = the first interlaced part or the second part. One of the interwoven portions of the interlaced portion or the like: the direction exists in a straight line, but refers to a case where the direction of the cloth is in a wave shape. The wavy shape refers to, for example, a shape of a sine wave, an - angular wave, a rectangular wave, a mineral tooth wave, or the like. Among them, it is a singularity, and it is preferably a curve like a sine wave at the turning point of 蜿. One direction in the nonwoven fabric of the present invention means that the longitudinal direction of the first interlaced portion and the second interlaced portion is as long as the effect of the invention can be ensured, and in the machine direction (MD direction) and the width direction (CD direction). Either one of them may be parallel, but it is preferable that the direction of the tang MD is parallel. Usually, since the tension in the assisting direction is applied to the fiber assembly during the manufacturing process of the non-woven fabric, the first step is formed along the assisting direction! The interlaced portion and the second interlaced portion are stably formed when the width of the desired interlaced portion is to be obtained, or when the second interlaced portion is formed by hydroentanglement to obtain regular weaving. The first interlaced portion and the second interleaved portion are preferred. The non-woven fabric of the present invention may include an interlaced portion in addition to the first interlaced portion and the second interlaced portion. The third interlaced portion may be formed simultaneously with the formation of the second interlaced portion after the formation of the first interlace = or after the formation of the second interlaced portion. The third interlaced portion may be formed to intersect the portion of the second interlaced portion or formed between the adjacent second interlaced portions (ie, 15 201223492 in the first interlaced portion, Mb 4, the third interlaced portion) It may be formed along the inside of the second interlaced portion, not in the direction of the direction in which the weaving direction is different, or in the direction in which it does not exist in a straight line, or in the direction of the non-woven fabric. It exists in a straight line, but the direction in which the direction of the weaving is different is shown in Fig. 15 as the direction of the non-woven fabric. The third interlaced part is :::: shape: non-woven, but As shown in the figure, one of the second interlaced portions is formed inside the first interlaced portion, and the first interlaced portion is formed in the second: parent mode. The width of the third interlaced portion is included in the third interlaced portion: : Width ': As long as it is assumed that the width is not more than 2 mm, more preferably the width of the three interlaced portions, and further than 5 〇 mm, the gas is further evaluated. * The width of the first interlaced portion is different from 5 to 3 mm. Moreover, the widths of the plurality of 帛丨 and 乂 woven portions need not be the same, and the second intersection of the first woven portions The width and width of the weaving department are not necessarily the same. There is no need to have the same for each of them. The first interlaced part of the hair or the width of the fabric of the father's weaving department of the non-woven fabric of the moon is used to improve the non-woven fabric. :: along the non-woven CD direction (horizontal direction) or the assisting direction ,:, for example, in each of the second interlaced parts, the width may not be; 4 eight not the best 婉蜒 the return point width χ (The following is also only the width 々 and the width of the other part 以下 (hereinafter, only 4 width Υ) is different. 'More preferably, the width of the return point is less than the window V of the other part. "Curry γ here" "Width Y" means the maximum width in the direction other than the width χ in the part other than the return position as shown in Fig. 14, and the part other than the return position means one 蜿蜒The part between the reentry point and the next reentry point. On the other hand, in the 1st 16th 201223492 =, the year of the year, it is preferable that the width x of the reentry point is different from the X γ system other than the part. More preferably, the width X of the reentry point is greater than Width γ of the outer portion. Each of the second interlaced portions and/or the first interlaced portion has a second width in the longitudinal direction of the non-woven fabric or the direction perpendicular to the longitudinal direction. The interlaced portion and the i-interlaced portion have ▲ or effect*, and the non-woven fabric surface can be multi-functionalized. The respective woven fabrics P and/or the ith interlaced portions have non-woven fabrics of different widths, and can be used for the pressurization described later. The water flow is sprayed through the opening member having a specific shape, and is formed by a method of forming the opening member to vibrate. Further, in the second interlaced portion, the width Y of the portion other than the other is obtained. If the width X is greater than the return point, the effect of the regular weaving of the second interlaced portion can be more circulated, and the width is greater than the width Y by the width of the second woven fabric. It is possible to further exert the effect produced by the regular weaving of the first interlaced portion. Further, in the case where the second interlaced portion is interlaced, the width of the wide portion of the retracted portion of the entangled portion of the first interlaced portion is stronger than that of the second interlaced portion. . For example, ^ ^ 1 -. Parent weave. The rule of 卩 is woven for open woven, the rule of the first father's woven part is woven A witch ^ ^ 不 _ t ^ ^ For the case of thousand, woven, you can get a sandalwood non-woven fabric, which is in the 蜿Chain 3 produced by 蜒 Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ Μ The wiping of the crease marks is higher.

Further, in the woven fabric of the present invention, it is preferable that the width Υ and the width X satisfy the above range, and 50% or more, more preferably 7 or more, of the number of creases of the woven fabric as a whole. Further, in the non-woven fabric of the present invention, the width of the plurality of second interlacing entanglements may be repeated a plurality of times in the direction orthogonal to the longitudinal direction thereof. It is also possible to repeat the repetition unit for the width direction of the plurality of 帛2 interlaced portions toward the direction 9 orthogonal to the longitudinal direction thereof. ^ When the non-woven fabric is used as the wiping material, the size and type of the dirt that is easily caught are depending on the width of the first interlaced portion or the second interlaced portion. Therefore, the non-woven fabric has the ith interlaced portion having a different width as described above. It is preferable that the second interlocking portion can wipe various types of dirt. ★ In addition, the conventional wiping material in which the entire surface is woven with a plain surface or a plurality of openings is formed on the edge of the surface of the rubbing material which is in contact with the wiping surface such as the body or the floor. Concentrated to rub the dirt, 'So 18 201223492 wipe the effective use of the rubbing material in contact with the rubbed surface, ° °. On the other hand, when the width of the plurality of i-th second interlaced portions is repeated a plurality of times orthogonal to the longitudinal direction thereof: P or a large repeating unit, the non-woven fabric has no one for the following reasons: The wiping performance of the central portion of the surface in contact with the wiping surface is a known wiping material. _ force non-woven fabric, as described above, if the width of the ith interlaced portion or the second interlaced portion is different, it is easy to capture 癖., 兮的女], 益#s卞^ (the size and type of dirty 5 are the same as 1 In this case, the wiping material is not captured by the 帛i interlaced portion or the second interlaced portion at the edge of the surface in contact with the wiping surface such as the body or the floor, that is, it enters the inner side of the edge portion, and is located at the inner side. The first interlaced portion or the second interlaced portion having a different inner width of the first interlaced portion or the second interlaced portion of the edge portion is captured, and the first interlaced portion or the interlaced portion of the second interlaced portion is not captured. Dirty, that is, the first interlaced portion or the second interlaced portion having a different width on the inner side is captured. Therefore, the width of the i-interlaced portion or the second interlaced portion is repeated in the direction of the / and the longitudinal direction. In the case of the non-woven fabric of the repeating unit in which the direction of intersection is gradually increased, the wiping performance is also better than the non-woven fabric in which the widths of the plurality of first interlaced portions or the second interlaced portions are exclusive. Further, the nonwoven fabric of the non-woven fabric of the present invention contains The width of all the first interlaced portions or the second parented portions is not required to satisfy the above range. The first interlaced portion or the second interlaced portion which is not included in the above range may be present without impairing the effects of the present invention. Among the second interlaced portion or the second interlaced portion included in the non-woven fabric of the present invention' When the number of rows of the first interlaced portion or the second interlaced portion whose width does not satisfy the above range is more than 5% by weight in the entire non-woven fabric, it is preferable that the wiping material is more excellent in wiping property from 19 201223492. Preferably, the second interlaced portion has a length (i.e., wavelength) per pass period of 5 mm or more. Further, as shown in Fig. 2, the second per i period. The length of the entangled portion is the forward direction (the positive direction) of the 蜿蜒 in the direction 32 (the orthogonal direction) orthogonal to the direction 31 of the second interlaced portion 42. The point in which the direction changes to 18 degrees (set to the negative direction) is the point e' and the point below the positive direction to the negative direction is the point "time (not the point that changes from the negative direction to the positive direction) a straight line containing the orthogonal direction 32 of the point e and a straight line containing the orthogonal direction 32 of the point f The length in one direction η!. In the case where the 蜿蜒 system changes from the positive direction to the negative direction in the case of a line parallel to the - direction 31 (for example, in the case of a rectangular wave) The midpoint of the straight line is set to a point that changes from the positive direction to the negative direction. If the shape is as large as a wiping material, the upper limit of the wavelength is preferably 200 mm. The wavelength is preferably 10 to 15 〇. The cycle, the step is preferably 30 to 100 mm. Thereby, the installation of the wiping device becomes easy, and the 'second interlacing portion' preferably has more than one vibration. The amplitude means that the point which changes from the positive direction to the negative direction by the above-mentioned 为 is the point g, and the point where the following 婉蜒 changes from the negative direction to the positive direction is the point h, and the line containing the point g is 爿And the length J in the orthogonal direction 32 of the line containing the direction 31. Here, the point g and the point h are located at the point where the second interlaced itch is a point such as the midpoint of the wipe width. When the size is used, the upper limit of the amplitude is preferably the outline. The amplitude is better 2~15Qmm, the better step is 5~1 〇〇, 20 201223492 is especially 10~50_. In particular, it is preferable that the amplitude sweptability is improved. The second interlaced portion (4) may be different depending on the period of the rubbing, or the length of each of the different amplitudes may be a regular repetition as in the case of the fading wave, and the lengths of the 蜿 periods are the same, and each Into: the repeating composition of each pattern is composed of each mouth, that is, the same ratio of green (four) frames, preferably the degree and amplitude, and the u * u u u u u 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 A better range is 2 to 8. If the ratio of the wavelength to the amplitude of fa @ is less than 1, the second interlaced portion will be a non-key cloth that exists in a straight line in the direction of the orthogonal 士士士, and the wiping property may be poor. . Moreover, if the ratio of the length of the skin to the amplitude of the 1st and the K# is more than 15, the second interlaced portion will be in a straight line in the direction of one of the woven fabrics. good. In Fig. 2, the example in which the second parent weaves are close to each other or the first key Α '°卩 is the same as the phase is shown, but as shown in Fig. 14A, the contact is broken, > The phase of the ridges of the parent woven portions or the first interlaced portions may be shifted. The WJ process for forming the second interlaced portion of the crucible in the present invention includes a method in which a support capable of forming a weft woven fabric is used as a support, and a method in which one or more small holes are provided at a specific interval is used. A method of forming a small hole group and causing the nozzle to vibrate, and a method of using a nozzle having a J-hole group at a predetermined interval and causing the carrier to vibrate without vibrating the nozzle to open the y, and adding The pressurized water flow is ejected through the opening member of a specific shape to a method in which the non-woven fabric 'the opening member is vibrated at this time. In the method of forming a support capable of forming a weft woven fabric as a support, it is preferable to use a support having a width of 21 201223492 which is widened by the first interlaced portion or the second interlaced portion. For example, it is preferable to use a support having a width of 2 mm or more for the 帛i interlaced portion or the second interlaced portion, and more preferably a 3 to 5 〇 axis for improvement of 5 to 30 mm. The hydraulic entanglement in this method:::' can be based on the amount of coating of the fiber web and the speed at which the support is transported. For example, the aperture 〇〇5 Ο'5· can be provided from 〇·2 to 1.5 mm. The nozzle of the small hole 'sprays a water flow of 1 to 2 MPa MPa from the opposite side of the fiber web to i to 4 times. More preferably, the water pressure is 1 to 1. When the K pressure is less than 1 MPa, the fibers are not interlaced with each other, and in the case where the cloth is easily detached, it is easy to cause the pile to fall off. If the water pressure exceeds, the fibers are intertwined with each other, and the degree of freedom of the (four) dimension is lowered, and the feeling of the touch is hardened or the texture of the non-woven fabric is deteriorated. In a method of forming a nozzle having a small hole group composed of a plurality of small holes at a specific interval and causing the nozzle to vibrate, a second interlaced portion is formed by a water machine in which a small hole group is formed. The interval of the adjacent small hole groups is preferably 2 mm or more, more preferably 3 to 5 mm, and still more preferably 5 to 3 mm. Further, the width of the 'one small hole group is preferably 2 mm or more, more preferably 3 to 5 mm, and the progress is more preferably 5 to 3 mm. The number of small holes contained in one small hole group is preferably two or more. When the number of the small holes is two or more, it is possible to reduce the ratio of the regular woven of the second interlaced portion to only the nozzle streaks. In the case where the small hole group is composed of two or more small holes, the interval between the adjacent small holes in the small hole group is preferably 0.2 to 1.5 mm. The hydroentanglement treatment conditions may be carried out by spraying water having a water pressure of 1 to 20 MPa from the nozzle and spraying one to four times from the front and back sides of the fiber web. More preferably, the water pressure is 1 to 10 MPa. If the water pressure is less than ΐΜρ&, the fibers are not intertwined with each other, and the obtained non-woven fabric is liable to cause thief 22 201223492 hair drool. When the water pressure exceeds 20 MPa, the fibers are interlaced with each other, which is too sturdy. The degree of freedom of the fibers is lowered, and the feeling that the touch is hardened or the texture of the non-woven fabric is deteriorated. In a method in which a nozzle having a small hole group is provided at a specific interval and the carrier is vibrated without vibrating the nozzle, a nozzle similar to the method described below can be used: a front-end is provided at a specific interval. A method of forming a small-hole group nozzle composed of one or more small holes and vibrating the nozzle may be performed under the same conditions for the hydroentangling treatment condition. Further, the method of vibrating the aperture member to form the second interlaced portion of the crucible is compared with the method of forming the support capable of forming the crucible, by changing the speed or width of the vibration of the aperture member, It is preferable to transfer the support body at the transfer speed or the like, and to freely set the length or amplitude of the #丨 cycle. Further, in the method of forming a support which can form a weft woven fabric, since the water flow touches the entire surface of the nonwoven fabric, it is difficult to obtain the difference in thickness or density between the first interlaced portion and the second interlaced portion. Moreover, the method of vibrating the aperture member is compared with the method of vibrating the nozzle provided with the aperture group at a specific interval. Since the aperture member is lighter than the nozzle, the equipment of the same cost can be used. It is possible to smoothly vibrate, and in particular, to smoothly perform the action at the turning point of the vibration, and it is preferable to sew a skein having a sinusoidal curve at the turning point as a weft woven fabric. In the case of the nozzle vibration system, the reciprocation point at the amplitude cannot be smoothly performed, and the reciprocation point (four) line (4) of the woven woven fabric is close to a straight line, and the vibration of the aperture member is closer to Curve 23 201223492 is quite woven, so it is better. Further, in the method of vibrating the opening member, the second interlaced portion of the crucible can be formed as compared with the method in which the blood vibrates the support member, and wrinkles are not formed in the nonwoven fabric. Further, even in the method of vibrating the opening member to form the second interlaced portion of the crucible, a nozzle having a small hole group composed of the above-mentioned small holes may be used at a specific interval. / In the method of vibrating the opening member to form the second (fourth) portion of the crucible, the perforating member having the porous opening member is placed in the nozzle of the jet pressurized water flow through the first interlaced fiber assembly Between the two, the pressurized water stream is sprayed through the opening member to the fiber assembly, and a part of the constituent fibers of the fiber assembly is rearranged by a pressurized water flow passing through a portion of the hole of the opening member to form a rule. The woven second interlaced portion 1 is a porous member, and the porous member is present at a specific interval. Therefore, in the non-porous portion, the pressurized water does not pass through the fiber assembly of the portion of the opening member. The first! The first interleaved portion that remains in the interleaved state. In this way, the i-th interleave portion and the second interlace portion are formed such that a plurality of columns exist in separation from each other. Then, at this time, the opening member is vibrated and the fiber assembly is moved, whereby the second interlaced portion and/or the second interlaced portion can be formed in a meandering manner. The opening member may be any member as long as it has a porous member. For example, the material may be made of synthetic resin or metal, and the shape may be a plate shape or a roll (four) shape. The device is properly selected. The weight of the opening member is preferably "retracted", more preferably h, and the weight per unit area of the opening member is preferably 5"2 0.1 to 3.5 g/cm2. Preferably, the plurality of holes have a width of 2 mm or more in the direction of 24 201223492 for vibrating the opening member, more preferably 3 to 5 mm, and further preferably 5 to 30 mm. Further, the opening member includes The spacing of the adjacent holes is preferably 2 mm or more, more preferably 3 to 5 Å, and even more preferably 5 to 30 mm. The shape of the holes may be any shape, for example, preferably circular. Polygons such as semicircles, ellipse, triangles or quadrangles, stars, polygons, crosses, straight lines or curved shapes, etc. 振动 The vibration direction of the aperture member, as long as the MD direction and CD direction are properly selected In addition, the oblique direction may be referred to herein. In the direction of the non-woven fabric, the angle from the MD direction exceeds the twist but does not reach 90 彳. In the case of simplicity, the direction of vibration is preferably more than 0 in the direction from the CD or MD. And the direction of the range below 45 degrees. Again, the term vibration refers to the reciprocating member moving back and forth in a certain direction, including the case of making it reciprocating on a straight line, or going back and forth along a circular orbit with a long axis in a specific direction. Further, the vibration direction of the opening member may be parallel or non-parallel to the longitudinal direction of the opening member, and the angle between the longitudinal direction of the opening member and the vibration direction may also be changed during vibration. The vibration speed of the opening member is It can be raised to about l〇〇m/min. On the other hand, in the case of vibrating the nozzle, if it is a device of the same cost, the vibration speed can only be increased to 1 Gm/min. In addition, by lifting the opening The vibration speed of the member can be increased by the difference between the width X of the folded portion of the interlaced portion such as the first interlaced portion or the second interlaced portion and the width γ other than the width γ. The distance between the 汗P sweat 1 hole member and the mouth is preferably better. The distance between the opening member and the small hole is preferably 30 mm or less, and the distance between the opening member and the fiber assembly is preferably 5 to 50 mm. If the distance between the opening member and the nozzle is less than 1 mm, Opening member and spray If there is damage to one or both sides, if the distance between the opening member and the fiber assembly is less than 5, the opening member will come into contact with the fiber assembly, and the fiber assembly may be damaged. If the distance between the member and the small hole exceeds 3 mm, if the distance between the phase hole member and the fiber assembly exceeds 50 Å, the energy of the water flow will decrease and the interlacing property will be insufficient. The opening member is vibrated to form a crucible. The hydroentanglement treatment condition in the method of the second interlaced portion can be appropriately set depending on the amount of coating of the fiber web and the speed of the conveyance support, etc. For example, a pore diameter of 0.05 to 设有 can be provided at intervals of 〇2 to 15_. The nozzle of the _5mm small hole sprays the water flow from the front and back sides of the fiber web 4 times. More preferably, if the water pressure of 1 to 10 MPa is less than 1 MPa, the fibers may be interlaced with each other insufficiently, and the obtained non-woven fabric may be liable to cause fluff falling off. If the water pressure exceeds $ 2 〇 MPa ′, the fibers are intertwined with each other to be too strong, resulting in a decrease in the degree of freedom of the fiber, and there is a case where the touch is hardened or the texture of the non-woven fabric is deteriorated. The non-woven fabric of the present invention is suitable for use as a wiping material, but is also suitable for water-absorbent articles in other applications (especially, surfac'e, second sheet (dsheet), gauze') Masks such as masks, fihers, packaging materials, mats (thin), cushioning materials, tablecloths (10) le Cl0th), carpet linings, and wallpapers. In the use of gauze, packaging materials, cushioning materials, and wallpapers, the excellent formability of the nonwoven fabric of the present invention can be exhibited. In the case of the use of the first interlaced portion and the second interlaced portion, the first interlaced portion and the second interlaced portion are arranged in the direction of the non-woven fabric in the direction of the non-woven fabric, in addition to excellent shape, Since it can also impart non-slip properties to the non-woven fabric and is stiff, it is slip-resistant in any direction. In the use of a water-absorbent article or the like, the flow of the liquid on the surface of the non-woven fabric is controlled by the interlacing 4 and the second parent-woven portion at a predetermined interval and in the direction of the non-woven fabric. leakage. In the use of masks, transitions, etc., pay? The portion and the second interlacing portion have different functions, and the t-functions such as 'in the transition device' have one function of filtering precision, and the other has a function of high filtration life.

Further, in the second interlaced portion of the 3_opening width, f, the width x is 2.8 mm, and in the first interlaced portion, the width x is 3'Gmm' in the second interlaced portion and the first interlaced portion. Because of the Qiu Ba worms outside the 折 折 & 、 [^ knife, almost the light becomes the opening woven, and the measurement is not performed for the width Υ. (Comparative Example 9) A non-woven fabric was produced in the same manner as in Example 9 except that in the second interlacing process, the mixed wavy streaks were not shown as straight stripes as shown in Fig. 12A. Tested: The physical properties of the non-woven fabrics of the examples and comparative examples and the wiping test were not shown in Table 1 below. 38 201223492 [Table i]

The non-woven fabric of Example 1 was not subjected to the wiping direction, but exhibited good wiping properties, and no wrinkles due to dirt remained. On the other hand, in Comparative Example 2, the non-woven fabric having the open woven woven on the entire surface, although the scraping property of the stain is good, but in all directions of MD, CD, and oblique direction, residual dirt is caused. Wipe the marks. Further, in the nonwoven fabric in which the entire surface of Comparative Example 3 was a plain weave, the wiping marks were not left, and the scraping property was insufficient, and the wiping property was inferior to that of Example 1. Moreover, in the comparative example, there are open-pore woven and plain weave, and these are formed into a linear non-woven fabric, although the scraping property is good and there is no wiping mark in the CD and the oblique direction, but in MD There are wiping marks in the direction. Further, if the stress in the MD direction of 1% is stretched, the strength of the non-woven fabric of Example i compared with Example 1 is the value between Comparative Example 2 and Comparative Example 3 39 201223492 'In Example 1 and Comparative Example In the first embodiment, the nonwoven fabric of Example 1 has a large strength.

Further, in the nonwoven fabrics of Examples 2 and 3, similarly to the nonwoven fabrics of Comparative Examples 1 to 3, the nonwoven fabrics exhibited good wiping properties, and the stress at the time of 10% elongation in the direction was larger than that of the non-woven fabric of Comparative Examples. Further, the non-woven fabric of Example 4 was less inferior in rubbing property than the non-woven fabric of Example 3, but the stress at the time of stretching of 10% in the MD direction was larger than that of Comparative Example 1. In the non-woven fabric of the fourth embodiment, if the reason for the poor wiping property is considered, the reason for the measurement is that the plain weave is woven in the non-woven fabric of the solid _ 4 compared to the width of the second interlaced portion which is the woven woven fabric. Since the width of the first interlaced portion is large, the scraping property of the opening portion is insufficient. Actually, in the non-woven fabric of the embodiment 3, the ratio of the width of the i-th interlaced portion to the width of the second weaving portion (the i-interlacing portion/the second interlaced portion), the non-woven fabric of the example 4 is 4 » 1^ θ The human soil J ί is wiped in the right direction, showing good rubbing properties, and the residual rubbing residue caused by the dirt is less. On the other hand, in the non-woven fabric of Comparative Example 4, although the properties were good, the wiping marks caused by the stain in a large amount in the MD, CD, and the oblique direction, the non-woven fabric of Comparative Example 7, 40 201223492, although the scraping property was Good, but in the direction of MD and oblique, there are a lot of wiping marks caused by dirt. In Comparative Examples 6, 8 and y, the scraping property of the dirt is good, but in the MD direction. However, there are a lot of things to do: the wiping marks caused by it. At the same time, the non-woven fabric of the plain fabric of the quilt and the perforated woven fabric of the sixth embodiment is compared with the non-woven fabric of the comparative example 4 of the entire surface woven fabric and the comparative example of the plain weave and the open woven fabric formed into a straight line. The 7 non-woven fabric is excellent in rubbing. Further, in the non-woven fabric of Example 6, the breaking strength of the non-woven fabric of Comparative Example 4 and Comparative Example 7 and the stress at the time of stretching were large, and the wrinkles at the time of wiping were small, and the fiber was Deloitte is superior to the aspect of 4. At the same time, the non-woven fabric of the seventh embodiment having the plain weave and the mountain-shaped twill weave is compared with the whole noodle-shaped twill weave ratio _ 5 non-woven fabric and the plain weave and the mountain-shaped twill weave formed in a straight line. Non-woven fabric, excellent wiping. Further, the non-woven fabric of Example 7 had a larger fracture elongation than the non-woven fabrics of Comparative Example 5 and Comparative Example 8, and was suitable for applications requiring stretchability. Further, the non-woven fabric of the seventh embodiment has a higher breaking strength than the non-woven fabric of the comparative example 8, and is excellent in handleability when tension is applied to the nonwoven fabric, such as when it is U栻.
