Vertically arranged single fiber 2 cloth 2 stretch non-woven U

The transversely stretched nonwoven fabric 4 is made by Tosei ^ stretched nonwoven fabric 4, which is composed of single fibers aligned in a normal direction, Λ C1 JX is sandwiched between longitudinal directions, and n M Cj. + No stretch, I cloth 2 and biaxial stretch nonwoven 4 have interlayer 3. This—longitudinal arrangement: direction, will be aligned with the single-dimensional arrangement of the transversely arranged fiber web 4 and the fiber arrangement. The intermediate layer 3 is dreamed and the right fiber arrangement direction is orthogonal to each other. Specially added persons with non-woven fabrics with orthogonal overlapping structures of 2 and 4 = As described above, 'Because this intermediate layer 3 is between non-woven fabrics 2 and 4, so: 4 places V month: Non-woven fabric 1 except longitudinally stretched non-woven fabric 2 In addition to the characteristics of the orthogonal overlapping structure formed by the transversely stretched nonwoven fabric 4, it can also have other functions. Mingzhi Orthogonal Laminated Non-Woven Fabric has a set of longitudinally stretched non-woven fabric 2 = directionally stretched non-woven fabric 4, so the intermediate layer 3 can be between the longitudinally stretched non-woven fabric 2 and the transversely stretched non-woven fabric 4. The manufacturing mode of this double-layer structure comes from the conventional orthogonal laminated nonwoven fabric with several layers of nonwoven fabric. The longitudinally stretched nonwoven fabric 2 and the transversely stretched nonwoven fabric 4 will be described in detail below. Taking a longitudinally stretched nonwoven fabric 2 as an example, the nonwoven fabric disclosed in Japanese Patent Laid-Open Publication No. 20 4 7 6 7/98 is used. Now, the longitudinally stretched nonwoven fabric 2 and a method of manufacturing the same will be described. 490524 Weaving several horizontal forces, so single fiber square, field meat / jel workers. To this end, the devices that spray out are all infrared. V. Description of the invention (4) In order to make a longitudinal tensile stress, the single fiber material is self-recovered and applied to the single fiber tensile belt. Ejecting from a nozzle says that the single fiber will be placed near a nozzle that ejects the single fiber. The temperature of the fiber melting point is about the same. The molecular orientation phenomenon is reduced. A device such as a self-spraying plate insulated cylinder or other similar device for melting single fiber materials can be used. The cloth 2, first, needs to be ejected from the nozzles arranged in a row so that the single fibers will become thinner and the stack will be immediately heated. During ventilation, this high-temperature air will maintain the temperature of the air. The air near the mouth due to tensile stress may be maintained in a heated airflow. Any heating can be used. As for the irradiation device or laser irradiation-stretching. Because the superimposed sentence is located in a high-temperature device and a heat-dissolving device just caused by the single and single fiber, the fiber material using the melt-blown Mβ method is not hot for this reason. Therefore, the method of applying a tensile stress to a single fiber obliquely to the conveying method may use a method of melting (blow die, hereinafter referred to as MB). The advantage is that the hot air can maintain a high temperature, so that the phenomenon of molecular orientation in the monomer can be suppressed. However, in the general MB method, it is irregularly stacked on a conveyor belt. Moreover, the single fiber will continue to be heated on the conveyor belt due to the flow, and its stretch will be changed. A mist-like air stream containing water vapor or the like will be blown toward the nozzle at an angle of the conveying surface. Sprayed single fibers. This allows the single fibers to be aligned in the machine direction and moderately cooled. V. Description of the invention (5) Narrowly referred to as the method of spinning turtle square, earth < eu,%. 锸 / ⑽-〇nd method, hereinafter referred to as SB) nozzle nozzles will be arranged in a plurality of air absorbers Quick cooling, so after m: fiber is ejected from the nozzle, it will also be fast, and single fiber only η early fiber: inside will also produce molecular orientation phenomenon. And it is also irregularly stacked in the arrangement of the fibers.) Similar to the device that can be used in the SB side and the SB side for improvement in the MB side, we use any method to make the nozzle near the nozzle. The area is maintained at g, and θ to suppress the phenomenon of molecular orientation. 夺 :: The misty airflow of the dagger will be supplied to the jet test = 卩 rolling & or a good stretch of moisture. This = inside ’, so that this single fiber has a fluid material of self- / 3 early fiber inclined to the conveying surface of the conveyor belt, preferably, because the single fiber is inclined to the conveying surface of the carousel belt =

Above, the household fiber will be arranged in a vertical direction with this single fiber ... so that the nozzle containing the single fiber C can be arranged at an angle to the carousel, or the single fiber is included here. Adding _addition to the fluid makes the direction of this single-fiber fluid tilt, or the conveyor belt can be arranged in the direction of the fiber ejection direction. The methods mentioned above ... :: use, or only use a few of them-together. If a liquid fluid is provided nearby, the fluid is preferably a heated fluid. Also, if there is no liquid fluid near the nozzle, the single fiber can preferably be heated. = s Because when a single fiber has a fine straight length due to tensile stress, it can fatally avoid the phenomenon of molecular orientation. , 'In the MB method or SB method, a single fiber fluid is tilted.

Near the conveying surface of the conveyor belt, this liquid flow is a misty fluid of water vapor. It is rapidly cooled, and due to the generation of crystals, the fluorine component of this single fiber is blown toward the pile, is stably fixed to the conveyance, and is ejected, and the liquid is arranged in a more liquid state. If the liquid is preferably a cooling liquid, it is a liquid fluid, which can avoid the lack of stretch of single fiber knots on the surface of the fiber mesh belt on the conveyor belt. Therefore, a good 0-shaped fluid is a phenomenon in which a nozzle-shaped fluid is supplied, and in particular, a single fiber ejected from a nozzle is crystallizable. If single fiber. At the same time, if the mist is water, the fiber web will be more single fiber and the web will be more stable. If it can be tilted so that the mouth can be effectively conveyed for a short time, the suction device will be conveyed in the same place and will show different purposes in one place, the same. During this spraying, it is sensitive. As mentioned, a single fiber will be piled with a device to remove the excess market from the fiber web on the conveying surface; if it is dry, the conveyor belt will remove the cross of the fiber belt. This fiber is usually placed on a regular basis in a unit plane. Water vapor forms this water vapor so that if a net is formed in the direction, it will be effective to have a wider width product uniformity. Therefore, the embodiment is based on the SB side embodiments. Therefore, the effect of the composition absorbs the net under the belt of the fruit fiber net and re-stabilizes the heat. Straighten up here to effectively suck. One . The distribution is extended in the general SB direction, and the use of the suction device in the general SB method is more movable and can be avoided later. The stretched polyester has no moisture distribution in the fiber web, so it is down. In the same example, if, in this extended SB method, the fibers are sucked, the suction device will be used to remove the excessive cooling degree. For water uniformity, if a fiber is pulled, it will be τ ' The suction force is also used to extend the force of the device. The fiber web is as strong as possible, and the gas is quite stretchable during the mist process.

Page 10 V. Description of the invention (7) = change = second sentence: The tensile strength of the fiber web is incapable of withstanding a large degree of stretching. It is composed of single fibers stacked on a conveyor belt and is stretched. Therefore, the fiber web will form a longitudinal stretch and will be aligned in the longitudinal direction. The fiber web can be stretched by longitudinal stretching: f cloth. The better the longitudinal alignment of this early fiber is, the longer it is when stretched. The higher the actual stretchability of the single fiber, and finally: the stronger the mechanical strength of the single fiber until 2: 犄 '. If a single fiber stretches the web of the fiber web, only the distance between the single fibers can be changed: the fiber has mechanical strength. There will be enough opportunities for the method to be completed when the fiber web is fed into the rod, and the stretching step is completed. However, the stretching process is mainly composed of a single step-the following steps can be taken as follows | . This stretching step is sprayed on the single fiber =: that is: the first of the stretching process—in the first stretching step, + ^ J enters the lamp to prepare for the stretching step. The next step is the second step performed as a main stretching process and a half-step stretching step followed by a short distance. In particular, the present invention is more suitable for the first stretching step.彳 is the difference between the short-distance stretching methods of the multiple stretching steps during the stretching process, so that a set of adjacent rollers of the fiber are stretched at the same speed. The term "short distance" means this, i page 11 5. Description of the invention (8) The distance is very short (Note: the distance from the beginning of the stretch to the end of the stretch: also this 3 5 distance stretching method is effective The stretching is based on the effective stretching distance of the rollers of the dagger, which should be, or less. In particular, in the case of Benben, although each single fiber is generally twisted in a longitudinal direction, but in a single dimension, maintaining a comparison between the rollers in this group (distance between mother and early fiber) is quite heavy :. == From the material (effective stretching and adding the roller F to fit ^^ 仃 When stretching at this distance, it is used to stretch the flow or infrared rays.

For example, the second stretching step of the stretching process, steam stretching, hot-set Γ wheel stretching, and hot-water stretching can be used in the first stretching step of -Single non-woven fabric 4; Do not ^ cloth / explain. The web was revealed with respect to a transverse stretch. Temple Xu Publication Gazette No. 36948/9 No. 490524 V. Description of the Invention (9) In order to manufacture a transversely stretched non-woven fabric, the webs are arranged in the orientation direction in this way, and they can also be produced in real time, with The single fiber of the spinning nozzle generates vibration in the transverse direction, and the method of using a ring around the spinning nozzle to generate vibration is as follows. Normally two to eight nozzles) will be equipped with a circle-type knot vibration from the centerline of the spinning nozzle. The first airflow consisting of a group of nozzles will blow out the periphery of the nozzle, and the second flow will be parallel. The single fibers ejected from the spinning belt mechanical spinning nozzle will collide with the first jet stream, while the second jet stream from the spiral-type exit nozzle collides. Therefore, the mechanical direction of this single fiber feeding belt. That is, the positive jet air flow is forced to move in a lateral direction and are arranged in a horizontal direction, and the stacking rate is distributed. First, a single fiber must be made. The single fibers are arranged in the transverse direction, and the single fibers are ejected from a spinning nozzle, and the air is blown out from the nozzle, so that the single fibers are stacked on the conveyor belt. The airflow nozzle makes the single fiber blow out a set of first airflow nozzles in the transverse direction (Note: It is placed around the spinning nozzle, so each jet airflow has a surrounding structure. At the same time, to ensure that the single fiber generates an airflow The blowing nozzle will be arranged in the direction of the direction of the jet gas blown out by the first air blowing nozzle. They will collide with each other. Since the rotation of the first air blowing nozzle blows out. On the other hand, the second air blowing will rotate the path of the single fiber. The upper fiber will be dispersed in the horizontal direction, and the single fiber lost in the rotation perpendicular to this will be the result. Therefore, the single fiber will be mostly on the conveyor belt.

Stretching a fiber ^: The fiber web made in this way is stretched in the transverse direction. In order to use a tenter system, a pulley system, or

Page 13

It is similar to the tenter system, which usually makes it used for diaphragms or similar wide systems. The disadvantage is that it can be easily changed or the transverse stretching rate of the product material is not used. When manufacturing a fiber web, the width of the fiber web should be considered as thick. =. On the same date, the stretching rate of the fiber web should be based on its original material sheet. In the present invention, when a fiber web is to be stretched laterally, the wind is caused by the pulley system even during operation. The product: see The degree or stretching rate can be changed. The stretching equipment of a pulley system has a set of pulleys arranged at the two ends of the fiber web at a fiber pitch: 'Slip Dry = ，, Dian Yuelun 糸, and the first pulley Hanbei, which also includes extensions to each ~ : i ϊ il: The pulley is a square trajectory symmetrical to the centerline of the fiber web. ⑲The pulley rotates at the same speed. Another Γ: each: ί A tension is stretched on it. -Part of the belt will murmur: to the outer wall of the mother, from the narrowest position of this group of pulleys to the grooves at the most spaced position. This web is on top of this set of pulleys. The web is held laterally. When the pulleys of this group rotate, the fiber web will be transported in the divergent trajectory of the pulley group. At the narrowest stretched position of the fiber web, the two ends fed to this stage will be fixed by a pulley set and a belt. The fiber web positioned between the pulley and the belt will be fixed. In this way, it can be stretched in the transverse direction, and a heat source such as heat can be added.

Page 14 490524 V. Description of the invention (11) Water, or hot air flow, etc. Fiber composition As described above ', a transversely stretched non-woven fabric 4 can be produced which is arranged and stretched in the transverse direction. The materials used to form the longitudinally stretched nonwoven fabric 2 and the transversely stretched nonwoven fabric 4 may be thermoplastic resins, such as jujube / secret, jujube high secret. Take this such as vinyl, acrylic, polyester, PVC, PVC, poly Carbamate, tired to shake the Japanese dagger, u ^ fat, etc. In addition, the wet spinning station is stationed in your field, and the ritual ^ Yan Γ ^ ^ ffl ^ ^ Λ stone, resin, or the tree used in dry spinning equipment, such as polyvinyl alcohol Either resin or polyacrylonitrile can be used. However, the above-mentioned stretched nonwoven fabric and the first preferred example are a single fiber and a net. The reason why this continuous single fiber has the tensile strength of the cloth is the first and the other one is continuously formed into a fiber web, after stretching and after stretching, g / d) ° Two examples are described as the first nonwoven and the second nonwoven, Although the cloth 2 and the transversely stretched nonwoven fabric 4 are used, the woven fabric of the present invention is not limited to the aforementioned nonwoven fabrics. The invention does ::::!: Formula production: After spraying out by a spinning device, the continuous fibers are arranged in a uni-direction, so that the arrangement direction of the continuous single fibers is to stretch the average straight ^ 2 stretch ratio of the fibers.

In addition, the tensile strength of the fiber web is preferably 100 to 300 mN / teX (1 ;; 1 to 3.4 / d), and the machine tension is 130 to 220 mN / tex (1.5 to 2.5 g / d). § ‘is more preferred. In this example, the single fibers constituting the longitudinally stretched nonwoven fabric 2 and the transversely stretched fibers are long single fibers. The long single fiber in this example produces a long. The term "long single fiber" means that the length of the single fiber is greater than 100 m :. Tian, § A specific example will be described below for the longitudinally stretched nonwoven fabric 2 and the transversely stretched nonwoven fabric 4. The longitudinally stretched nonwoven fabric 2 is made of polyester as a single fiber. The single fiber is ejected by a melt spray plate with a certain width. The ejected single fibers are stacked on a conveyor belt to form a fiber web. This web is then stretched at a rate of j to 30 times. Therefore, a longitudinally stretched web composed of single fibers having a diameter of about 1 to 20 # m can be obtained. The longitudinally stretched fiber web prepared according to the above process has a fiber amount of about 3 to 20 g / m2 per square meter, a longitudinal magnification of about 7 to 15%, and a longitudinal tensile strength of about 8.83 to 883 mN / tex (1 to 10 0 g / d). Among them, the lateral magnification and tensile strength are not measured because the single fiber bundle will be decomposed and cannot be measured. Here the magnification and tensile strength refer to the values when the web is broken. The same is true of another example to be described below. In the case of Takimura Jishin Nonwoven 4 ', polyester is used as a single fiber material.

Page 16 490524 V. Description of the invention (13). Single fibers vibrate in a transverse direction and are stacked on a conveyor belt to form a fiber =. The fiber web formed on the conveyor belt is stretched 3 to 30 times in the transverse direction by a pulley system. Therefore, a transversely stretched web composed of early fibers having a diameter of u20 # m can be obtained. The transverse stretch obtained in the above manner = woven fabric, with a fiber mass of 3 to 2 Gg / V per square meter, two ΓΓ / two f7 to 15% in the transverse direction, and a transverse tensile strength of about 8.83 to 883 mN / tex (1 to 1's): the magnification and tensile strength in the transverse direction have not been measured, because the early and the dimensional bundles will be decomposed and cannot be measured. Fabrics, films, etc. As for the middle layer 3, a variety of materials such as Non-woven fabric can be used as the material of the intermediate layer. In the following, the intermediate layer 3 will be described in detail (melt-blown non-woven fabric). Melt-mouth non-woven fabric is a kind of cloth. The function of this melt-blown non-woven fabric is similar to other features. However, the amount of fiber is more complex. Less, so its resistance to this melt-blown non-woven fabric is very useful as an intermediate layer, then the melt-blown surface tension difference, etc. can be overcome due to vertical. Households, to melt-blown non-cloth, will not only have enough Straight shuttle resistance of about 2 // m includes filtration, tensile strength or surface limit of this melt-blown non-woven fabric. However, if the disadvantages of non-woven fabrics are used to stretch the non-woven fabric to intermediate tensile strength and the surface is extremely thin, it is resistant to water due to its tension. If this is the case, Straight tension, fiber non-woven bacteria and anti-lice or difference per square meter. Therefore, the melt-blown non-woven sheet tensile strength or surface stretch non-woven cross-laminated non-woven and can also have page 17 V. Description of the invention (14) There are special spray nonwovens for the petrochemical of melt-blown nonwoven fabrics.

Therefore, at this time, the laminated nonwoven fabric is further subjected to heat. Page 8 490524 V. Description of the invention (15)

It is firmly bonded to the longitudinally stretched nonwoven fabric and the laterally stretched fabric. The single fibers of this spunbond nonwoven fabric are interlocked with each other. In addition, the μj will be entangled with each other, and the connection is quite elastic. Therefore, the orthogonal laminated non-woven fabric without its single fiber interlayers is dispersed during the sewing: = spunbond non-woven fabric is dispersed as a medium, so the sewing strength can be improved. The stress applied by the thread will be as described above.
