593838 A7 I-— B7 V. Description of the Invention (l) ^ -'-- 'A " — Technical Field The invention relates to a kind of multi-layer paper, especially a method of manufacturing a single-layer coin with at least two layers. The bottom layer is first formed on the m-line, and at least the top layer is deposited on top of the bottom layer, and it is supported by the -wire when the I layer is deposited. The bottom layer and at least the top layer are deposited by a 1-dimensional suspension spray method. Therefore, the bottom and top layers of the deposition are formed by the twin wire technology. BACKGROUND OF THE INVENTION When a flexible paper is manufactured by a conventional method, it is usually formed in a multilayer manner. The conventional multilayer forming method makes the relationship between price and product ideal by using different furnishings on different layers. For many paper items, multilayer & technology increases the proportion of recycled paper and high-yield pulp, which is very beneficial in terms of price and environment. Multi-layer forming technology can be mainly divided into three categories: forming layers on respective forming units when joining layers together. With a multi-layer flow head divided into several layers, all layers can be formed on a forming unit simultaneously. The fabric layers are continuously formed in an overlapping manner, that is, a second layer is formed on top of the first layer and the like is formed. The invention belongs to this type. Techniques for forming layers of tissue paper articles on a separate forming unit before bonding layers together have been disclosed in WO 95/13424 and WO 96/35018. However, a problem with each of the techniques of forming each layer separately is that the layer bonding limits the z-direction strength of a multilayer article. Generally, powder or other cement must be sprayed on the layer before the layers are joined. It is also possible to form a multilayer product at the same time. The example of the multi-layer flow box has been turned over to the paper standard _ M specifications __ 7 public love) '-

V 4 593838 A7 ---- B7____ 5. The invention description (2) was disclosed in EP 0681057, and WO 95/13424, WO 95/35018. However, this method can also have some problems. This simultaneous forming technique makes it difficult to achieve the characteristics of an acceptable layer. In addition, the technology of forming with first-class bins and a single dewatering unit has its limits on the possibility of maintaining a low flow bin concentration ', especially for soft papers (single-layer items) that require high viscosity and a high basis weight. . A low forming concentration is a condition for producing good strength by using raw materials. In addition, since all layers are formed at the same time, it is impossible to make the layers have a different basis weight pattern. The use of double-filament technology to form two-sided or single-sided dewatered multilayer paper in a continuous manner has been disclosed in U.S. Patent No. 3,821,073. The single-sided dewatering technology was also disclosed in SE0002998-3. The technique of forming double-sided dewatering and multi-layer flexible paper in a continuous manner is disclosed in WO99 / 09249. The problem of layer bonding when the layers are formed separately and then bonded together can be avoided by the method of the present invention, which generally deposits fibers on a pre-formed layer to obtain a good layer bonding. This means that the strength of the zigzag direction of the product of the layer is often determined by the strength of the z-direction of the individual layer 'rather than the layer bonding. Under the circumstances, it is difficult to produce a double-layered soft paper 'using conventional techniques, wherein each layer has a different pattern from the others. In particular, a pattern that does not depend on the pattern of other layers cannot be obtained on the intermediate layer. Therefore, multiple layers must be used, which are laminated together in a conversion manner, such as glue, embossing, etc. to obtain the desired item. In addition, several steps in the conversion method, such as embossing, often cause damage to the product. ϋ This paper size applies Chinese National Standard (A4) (210X297 mm) (Please read the precautions on the back before filling this page)

Description of the invention (3) Description of the invention The new product can be obtained by the two-filament method according to the present invention, in which a pattern having a basic weight distribution is formed in the forming step. At least one layer. The middle layer and the outer layer may have different characteristics to cooperate with each other. The middle layer of 〃HAI can be provided with thickness and strength, while the outer layer can be provided with soft, thick chains and strength. For example, the combination of strength and absorptivity, strength and smoothness, absorptivity and strength can be selectively selected and combined with the appearance, function, and characteristics of the layer to be improved by the method of the present invention. This double-sided approach can be achieved with a single layer of fabric or article. This double-sided approach is more advantageous when using at least three layers. An object of the present invention is to provide a method for forming at least a plurality of layers of flexible paper, the paper including at least two layers, at least one of which includes a plurality of different patterns caused by a difference in basis weight. This layer shows the difference in the basis weight of a pattern formed by a patterned silk thread, so that when dewatering on one side at the same time by the double thread technology, at least one of the solid materials in the layer, such as fibers, filled with media, etc. Local displacement and redistribution will be formed on the solid part, and local redistribution depends on the pattern. Therefore, the pattern is composed of a local selection area on a layer including more material and a local selection area having a substantially lower material ratio. This means that the basis weight of the layer above the local selection area with more material is substantially higher than the local selection area for materials with lower or substantially no or no basis weight. The multilayer flexible paper, which is preferably a single layer of thin paper, can compete with the multilayer flexible paper having at least two layers made according to the method of the present invention. First, a fiber-equipped base layer is formed on a thread or the like by an alternative method. At least one top layer is then deposited on top of the bottom layer.

The total number of layers on a multilayer product may be two. From three to many layers. The layers are stacked on top of each other in a continuous manner to form a unique and clear pattern. The bottom layer refers to the layer formed on top of the next layer. That is, the layer that is always formed on the bottom layer. The top layer is formed on it. As a result, the top layer refers to the layer that is formed on top of the formed layer. The __ layer formed first is directly against the silk, and the line is also π, and is not formed on top of the formed layer. ⑽, so it is not a top layer. 纟 The first layer of a soft paper product towel can be formed at several different positions on the article like any layer according to how it is connected to other layers. Because & all layers Both can be the lower layer, the upper layer, or the middle layer. A pattern can be formed first by using the two-filament technology by localized subdivision formation in the layer, that is, on the plane of at least the solid part of the solid material on the fiber. On the bottom layer, so that The pattern on the layer is formed on the bottom layer at the same time of dehydration, and the partial redistribution depends on the pattern. The first layer of the fiber configuration can also be formed on a line with a pattern or without a pattern in an alternative method. At first, a bottom layer is first formed, and at least one top layer is formed on top of the bottom layer by a single-sided dehydration method when it is formed on at least one solid part of the formation area in a direction from the bottom layer upward. At least one solid part is formed by single-sided dehydration. When depositing and forming the top layer, the first formed bottom layer is supported by threads and the like.

7 593838 A7 --- B7 V. Description of the invention (5) '~ a ~ When forming the top layer, a pattern is formed on at least one of the top layers, and the top layer is above any previously formed layer. The pattern is completed by partial redistribution in the plane of the layer, that is, at least a solid portion of the solid material on the fiber arrangement, so that the pattern on the top layer forms a previously formed any-layer when dewatered at the same time. On top. Partial redistribution is based on the desired pattern. The chemical pattern is preferably formed by a patterned silk thread, which is formed in the double thread pliers-, # when the fiber is dehydrated through the silk to form the top I. The second thread is composed of a thread supporting the bottom layer. If the pattern has been formed on the first formed base layer in accordance with the above method, the other layers may also be free of any pattern. By the method of the present invention, it is possible to form a layer on top of another layer which is not the previous layer in a separate method. In this way, very different products can be formed, in which, just like one or more layers in the middle layer, the outer layer can basically be composed of any pattern. A tissue product, which was previously impossible to make, and which is substantially independently added, can be made by the method of the present invention. Another object of the present invention is to prepare a layer having a discontinuous pattern. The discontinuous pattern is composed of a solid material, in which selected partial regions formed of a solid material within a layer are mutually restricted and are not connected to other partial regions formed of a solid material. As a result, the partial area with a basis weight is distinguished from the other areas with a basis weight and is therefore surrounded by a zone without and especially without a basis weight. The localized areas are located separately, that is, the so-called discontinuous areas formed by solid materials are composed of locally small, or relatively small, finite areas, but they may also be constituted by non-continuous extended areas. The present invention also includes other patterns', just like the above-mentioned discontinuous patterns, which cannot constitute a self-supporting strip. Standard ⑽) M size ⑵ox gift)-^ -—

Description of the invention (6) Another object of the present invention is to form different reinforcing patterns, including the so-called discontinuous reinforcing dagger pattern and continuous reinforcing pattern. This pattern is composed of a pattern in which a distance layer is provided, and therefore has different characteristics. By forming different patterns on this layer, the total strength of the inner layer can be improved, and the smoothness and softness of the outer layer can be improved. In addition, according to the present invention, other patterns can be formed to improve the absorption ability of the inner layer and the firmness, softness, or strength of the outer layer. In addition, the clear visual patterns include, for example, patterns, symbols, characters, and labels, and the patterns formed during dehydration can also be added as one or more inner layers. The pattern may consist of geometric, descriptive or purely beautiful patterns, or may consist of company-related trademarks or designs or company products. The invention also includes patterns that are purely decorative or functional, or patterns that are both decorative and functional. The size of the pattern is larger than the holes in the woven pattern on a thread, and is usually 0.1 mm or larger. Such a pattern can reach the size of the fiber. For example, a pattern with a size of 10- 100_eds mm can be used. Another object of the present invention is to form a soft paper with higher strength. It can be formed in several ways, one of the most important of which is to make a single layer of soft paper consisting of several layers on a paper machine and form a finished product, which is not combined into one by a manufacturing method that reduces strength Layer product. A single-layer article with the desired basis weight pattern is immediately made by the papermaking method and can include one or more steps in the conversion. Some steps can be, for example, bonding multi-layer products with glue and embossing, but no matter which method will damage the strength of the product. Therefore, the conversion step usually means a reduction in the strength of the product many times. In general, the decrease in strength must be compensated in any of the above steps of the method, such as using more or stronger fibers.

9 593838 A7 ---------— _87 _ V. Description of the invention (7) — ~ According to the method of the present invention, the strength in a completed single-layer article is not reduced because some conversion steps can be added . This means that the use of the strength of the fiber material is better on the finished product because the strength can be maintained. In addition, the layers of the single-layer article according to the present invention are very well maintained together. The use of this improved strength is obtained from a single layer, and the multilayer flexible paper of the present invention can be used in several ways. Fibers with lower strength can be used, or smaller amounts of fiber can be used while still obtaining the same product strength. Alternatively, the recycled fiber is more expensive than used with 刖. Therefore, low-cost fibers can be obtained, and virgin fibers can also be obtained at low prices. It is also possible to make products with less basis weight or stronger products at the same relative strength. The improved relative strength can also be used to increase the thickness with a maintained strength and increase the softness and absorbency of the paper. Another object of the present invention is to produce a multi-layer flexible paper whose finished product is a single-layer product and which can be patterned on one or more layers independent of other layers. The pattern of at least one top layer is formed independently of the pattern of the previous layer. This can be done by the method of applying for the scope of the patent. The soft paper whose pattern is formed on the top of the formed bottom layer by the double-filament technology has considerable technical and commercial value, and can be made into many different products that do not appear on the market. An object of the present invention, which is very important from a commercial point of view, is to make a single-layer product having at least three layers, at least one of which is provided with a pattern. To form a single layer of soft paper that is generally symmetrical, three or more layers are preferably used. Another object of the present invention is to form a discontinuous layer in the middle. In this way, compared with the use of a completely continuous layer, the same amount of fiber can be used to obtain a thicker thickness "丨 ~ ——N, 丨 丨 1 _: ^ paper Scale Gu Jin Guan Jiaxian (CNS) A4 specifications (210X297 public director) '· -10-

degree. Thicker middle layer, highly absorbent products, consumers like. And it is not necessary to cover the entire area with fibers, and it can be obtained with relatively high softness and sagging. Therefore, it is possible to manufacture continuous, partially discontinuous or completely discontinuous layers, that is, non-self-supporting patterns. Layers. The choice of layers results in higher strength, less rigidity 'controlled hip flexural firmness, increased thickness, higher absorption, higher storage, lower or higher two sides. Brief description of the circular form The present invention will be described below with reference to the embodiments and drawings. The dark portions shown on the individual layers in Figs. 5-10 represent localized regions, which are composed of more materials, such as fiber ' fillers and the like. Therefore, black represents the major part of the constituents on the paper in the layer.

Detailed description of the embodiment of the invention.

According to the embodiment shown in FIG. 1, a top layer of a two-layer structure is self-injected into a first-class bin 1 in a pair of wire pliers between a tension forming wire 2 and another tension wire 3. The fibers are sprayed in a suspension spraying manner, and the two filaments are wound around a forming drum 4. Another preferred embodiment is to form a three-layer structure. However, the number of layers is optional, and it may be a four-layer structure as shown in FIG. 2. All features encompassing the present invention are that the top layer is formed on a bottom layer or a previous top layer by redistribution on the layer ', i.e., the plane of substantially all fibers on the layer, and single-sided dewatering is used with this formation method. The displacement of at least a substantial portion of the solid material on the top layer causes the fibers, fillers, and other solid elements on the fiber arrangement to be transported and follow the water, and to accumulate on the area where the water is discharged through threads or the like. In the area where the drainage volume on this layer is small, there is a corresponding or very small amount of fiber material, or other solids of the components in the fiber arrangement. Therefore, different layers having different patterns and forms can be formed. See Figure 5-10 for an example. This technology can form different products, several of which will be explained below. In addition, a good joint is formed because the top layer is in contact with the previous layer, and the top layer is in the form of a fiber suspension. A layer of good purity and a layer formation can be formed on the newly deposited layer because the fiber arrangement having a low concentration can be dehydrated through a new non-woven yarn or the like. This single-sided dehydration also caused the paper size on each layer to comply with the Chinese National Standard (CNS) A4 specification (210X297 mm). 12 V. Description of the invention (10 Good Z-shaped strength, because water is the same on each separate layer. The layer is weakened when dewatering on both sides and water is discharged in different directions. Another advantage of the present invention is the control layer bonding. It is best to use the following steps, such as wrinkling, in the paper Delamination occurs on a certain plane. The advantage of this step is that the separating layer can obtain #good z-shaped strength, and can obtain good layer bonding between the layers that do not need to be separated. A weakened layer bond is provided between the layers. For example, the discontinuous layer 7 shown in Figure 5 has a lower surface area where layer bonding can occur. In this way, a weakened layer bond can be formed, which can be used to produce delamination in the next step Another advantage of the present invention is that the patterns of the separate layers can be selected independently of each other. Even a separate top layer can be selected independently of the other layers. Therefore, the reason for this is that The reason for this is that the top layer can be formed on the top of the bottom layer or on the previous top layer by dewatering on one side of the formation area to the solid part in a direction outward from the bottom layer or the previous layer. The silk supports the bottom layer, while the previously formed fibrous fabric fixedly supports the top layer. The bottom layer can be formed by double thread technology, or by other forming techniques. In addition, the 'pattern is one of the solid materials on the fiber configuration when dewatering at the same time. Redistribution within at least a substantial portion of the layer, such that the difference in local basis weight is formed on the plane and is produced when the bottom layer is formed. The bottom layer and / or the top layer may or may not have patterns, and these patterns may be selected The ground is different, and each layer can be used as an outer layer, a middle layer or an inner layer.

Description of the invention (U) The injection of the material box is introduced into a pair of wire pliers, which is called the gap formation in Figure 1_2. Figure 3 Mixed forming, as shown in Fig. 4, a dewatering unit that drains upward after the second head box on a fourdrinier paper machine wire, or other similar methods. Therefore, the two-filament technology includes all forming methods in which two filaments form a forming area. For the manufacture of soft papers requiring high machine speeds, it is best to use a method of ejecting the headbox directly into the bimetal pliers' to obtain a closed forming zone. Drum forming belongs to this category (non-pulsating dewatering pressure) 'blade forming (pulsating dewatering pressure) and a combination of these two methods. Some examples of this method are disclosed in US 3,056,719, EP 0 699 798, EP 0 454 989, WO 95/34713, US 5,282,933, WO 97/47803, US 4,790,909, DT 2 000 661. The preferred embodiment shown in Figure 1 shows a roll forming in which the fibers are suspended and ejected into a pair of wire pliers formed by two wires entering an infinite loop. When forming at least a solid part of a forming area formed on one or more curved surfaces 4, 14, 114, 1114, dehydration is performed unilaterally by the water-impermeable curved surfaces 4, 14, 114, 1114 to Prevents dehydration through the inner threads 2, 3, 23, 113. Alternatively, single-sided dehydration can be achieved by the watertight inner wire 2. A solid part of the dehydration is carried out through the second silk_outer silk 3,13,113,1113, that is, water-permeable or partially-permeable silk. Thus, when a bottom layer is formed on the curved surface 4, or when a top layer is formed on the curved surface 14 on the bottom layer, or when the top layer is formed on the curved surfaces 114, 1114 on the previous top layer, due to the wire 2 or on the wire 2 The upwardly extending curved surfaces 4, 14, 114, 1114 are impervious to water. Prevents dehydration through this layer. Therefore, the single-sided dewatering bottom layer or top layer and a suction box 6, 16, ιΐ6, this paper size applies to China National Standard (CNS) A4 specifications (210X297 mm) S (Please read the precautions on the back before filling this page) . 、 可 |

14 593838 A7 ____B7 V. Description of the invention (12) The inner wires 2, 3, 13, 113 on 1116 are separated, and follow the corresponding outer wires 3, 13, 113, 1113 toward the next forming unit, where one of the top layers is formed on On top of the previous layer. Each dehydration unit should have good dehydration power, especially when equipped with high machine speeds. Therefore, the present invention can be applied to several different types of forming parts. See the examples in Figs. 1-4, which all include the two-filament technology / the two-filament forming technology. The two-filament forming process is performed in a forming area extending between threads or the like on fixed and / or rotating machine elements. Since the thread extends in the form of a piece or the like on the machine element, it does not form a continuous surface, and single-sided dehydration can be accomplished using water-impermeable threads or the like. In the two-filament forming step, the immediate dewatering pressure is supplied by the tension of the outer filament and is related to its radius of curvature. When the thread is extended on the rotating drum, the dewatering pressure can reach a fixed level in an increasing phase (according to what Webster calls roll forming). This is beneficial to the manufacture of soft paper, such as the retention of the thread and the use of the strength of the raw materials used. Alternatively, the dehydration is performed at different or pulsating dehydration pressures, with the threads extending over a fixed machine element, such as a fixed sheet or strip. In addition to the dehydration pressure induced by thread tension, dehydration can be enhanced in other ways, such as by vacuum. ^ As shown in Figure 1, according to the Webster's drum forming method, where the fiber is suspended and injected into the twin wire at -speed!! The external tension thread 3 is deflected, and when the external thread 3 is deflected, the substantially fixed tension is maintained by the external thread supported by the -rotation support portion 5, and at least one of the threads is erected elastically or displaceably. To compensate for this bias. Therefore, the outer silk thread 3 is erected to make it: this paper size applies the Chinese National Standard (CNS) M specification (21〇 > < 297 public love) (Please read the precautions on the back before filling this page)

15 593838 Α7 Β7 5. Description of the invention (13) Deviation. And the radial position of the outer wire is not in front in the forming step. The radial position along the periphery of the drum is determined by the following factors: the thickness of the fiber arrangement's material concentration on the fiber arrangement, the discharge resistance of the fiber arrangement, the thread tension, and the possible vacuum in the forming drum. The injection has enough kinetic energy to bias the outer wire and penetrate into the forceps. The Webster method is disclosed in U.S. Patent No. 3,056,719. The forming can also be accomplished by a fixed metal configuration or a fixed suspension, as disclosed in U.S. Patent Nos. 3,543,834 and 3,821,073. According to the present invention ', the forming is started first, and this step is completed on the forming wires 4, 14' 114, 1114. The fibrous fabric structure is then substantially fixed so that no substantial fiber redistribution is performed as the fabric passes through additional dewatering elements. Further strengthening of the fabric can then be performed according to conventional methods before the fabric enters the press or drying section or other subsequent units or sections, such as joining drums, suction boxes, etc. The forming of each top layer is performed on a separately selected and adjusted wire 3, 13, 113 1113. To form a pattern on the layer. Therefore, each layer accommodates a fully adjusted silk thread, and a patterned fiber fabric is accommodated by the silk thread and the like. In addition, the pattern can be changed by changing the thread. The dagger pattern can have purely beautiful features, or can affect different physical material characteristics of the finished soft paper. The following will be described in detail with reference to the preferred embodiment of FIGS. 5-10. The soft paper fabric or article of the present invention is characterized by thickness, firmness, strength, ductility, absorption of part of water and part of high viscosity fluid, and anisotropy.

19 593838 V. Description of Invention (17) Processing. The fibers or puree can be ground, filtered, cleaned, blanched, and processed chemically and / or mechanically, and it includes general raw polybutadiene and / or configured steps. The finished fiber-based product may also include processing chemicals, such as holding devices or functional chemicals that give the finished product special characteristics. For example, it can be a retaining agent, a coagulant, a filler, different reinforcing strength agents, a softener, a slurry pH control agent, a hydrophilic agent, an absorbent, a stabilizer, a bleaching agent, and the like. The chemicals that can be used in the present invention are not limited to the above, and include other conventional methods or functional chemicals. In addition, the fiber arrangement may be water-based and other fluids may be part or main part thereof. Different forms of digital or non-digital patterns can be arranged on any soft paper layer as a base weight pattern with one or several holes and one or several fibers gathered to design the desired pattern. The desired pattern, which is different from the conventional basis weight pattern made by other methods, is characterized in that the lower basis weight region has a very low basis weight, especially when there is virtually no or no basis weight 'to form holes in the actual layer Or open. Holes or openings in one or more inner layers may be surrounded by other layers. Watermarks can be formed on the patterns made according to this method, such as the numerals 12 and 14 in Figs. The discontinuous pattern is shown in the preferred embodiment according to Figures 5-7, and it is a pattern with a basis weight, in which the solid material 'especially fibers and fillers on the fiber arrangement have gathered in completely separated Area. Therefore, it is a region on a layer made of fibers constituting a discontinuous pattern. Therefore, the layer with a discontinuous pattern is not self-supporting, and it is difficult or even impossible to make it by a conventional method, but it can now be made according to the method of the present invention.

-20 593838 V. Description of the invention (18 A7 B7 Of course, the pattern creation area in Figures 6 and 7 can also be composed of empty parts, or parts whose base weight is lighter than the base weight of the surrounding area. Prepare A layer of a discontinuous pattern 7 can be used as one or several intermediate layers, as shown in Figure 5. The discontinuous pattern creates a thickness between the outer layers, thus creating a distance layer. A discontinuous or non-uniformly shaped middle The distance layer can create a thick, high absorption and storage layer. In addition, the thick, thick feel can give consumers a good feeling. In addition, very viscous fluids or other fluids can be very good way Storage. When the middle layer is a non-uniform layer, rather than forming a uniform thickness layer of extra thickness, it will be compensated by the strength on the outer layer. The discontinuous pattern 7 may be optional, other suitable discontinuous patterns 9 Examples of 11, 13, 15, 17, 21, 23 are shown in Figures 6-7 and 9. The discontinuous regions of solid materials 8,10,12,18 consist of smaller regions and relatively small surface confinement regions. Composition, shown in Figures 7 and 9 The example shows the discontinuous patterns 13, 15, 2 and 23, which constitute the continuous extension regions of the solid material 14, 16, 22 '24. Therefore, the regions constituting the discontinuous pattern can be composed of discontinuous or continuous patterns. It is also self-supporting. The pattern in the middle of the article can create a completely new pattern. In addition to pure patterns, it can also include patterns and functional purposes, or have only a certain function. The pattern on the middle layer can be protected by the outer layer, which can It is continuous or partially discontinuous. One of the most important applications is a single-layer article with at least three layers. The pattern on the middle layer can also be discontinuous. As shown in Figure 5, the first The formation layer, that is, the bottom layer, can form a patterned layer like the top layer formed later. If a reinforced pattern is required, a so-called discontinuous reinforced pattern can be formed. The paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm).

21 593838 A7 ^ ______ B7 V. Description of the invention (19) Look at Figure 8, for example, the so-called raised pattern 17. Where the fiber threads need to form a reinforcing pattern, the fiber threads usually intersect, and an opening is formed in the pattern as an interruption in the pattern. This is particularly advantageous because strengthening also indicates its stiffness. By not having a continuous reinforcing pattern, and using a so-called reinforcing pattern, leaving a fibrous pattern usually requires a cross-cut opening, which reduces the effect of stiffness. No fibers cross each other and the openings are sufficient to break the stiffness. In addition, different continuous reinforcement patterns can naturally be used in the article, see figure 9. An example of the reinforced pattern that can be formed on one or more layers is a reinforced portion having a pattern of machine directions 15, 21 in FIG. 9. The bending stiffness or elasticity is usually different in the longitudinal and transverse directions of the machine. It is not complete, but may be formed by subsequent enemies. In addition, it reduces the resistance to bending, and the bending rigidity in the machine direction. Therefore, strong base weight patterns 16, 22 in the longitudinal direction of the machine 5 and 2 can create bending firmness in the machine direction and create strong and weak base weight patterns in the transverse direction. By creating a higher bending firmness in the machine direction, the bending firmness is reduced in the subsequent wrinkling step, so that a more uniform article having bending firmness or elasticity in the longitudinal and transverse directions can be formed. A reinforcing pattern can also be formed so that the layer is strengthened in the cross direction 21 of the machine. Use this pattern and similar patterns when you want to enhance the wrinkle effect. Due to the reinforced features of the intermediate layer, the outer layer is mainly designed to be soft. According to the invention, the layer can be created and combined in different ways, and a single layer of articles can be made in an unlimited way. A good example of this article in Figure 10 is a three-layer soft paper with an outer layer, which has a large opening. 31 The paper size applies the national standard (国家) A4 size (210 X 297 public love) (please first (Read the notes on the back and fill out this page)

22 593838 A7 _____B7 V. Description of the invention (20) is formed so that the fluid or oil with viscosity to penetrate into the material. The intermediate layer is a layer that gives a feeling of thickness, for example, a discontinuous intermediate layer 32, which is provided with a fiber gathering area of a solid material 33, and absorbs and stores a high-viscosity material in the middle. The second outer layer is composed of a flat or rough surface to have good absorption of water or low viscosity fluid. In this way, one-sided or two-sided articles can be formed. Of course, they can also be formed in other ways or be equipped with other functions according to the needs of the manufacturer or the consumer. Coloring certain patterns with the basis weight creates unique and clear patterns on the item. At least one top layer may be colored differently from the other layers. One example is a fiber arrangement for discontinuously selectable patterns on the inner layer plus one color, while the outer layer has another color. This is particularly advantageous when using numbers, trademarks or other aesthetic or functional graphics. Examples of discontinuous and continuous patterns are shown in Figure 5-10. Of course, different fiber configurations can also be used on different layers. Faces formed in a single dryer are usually smoother than the cover. And many important bulk items, such as toilet paper and household paper, must be largely symmetrical. The two sides prepared by a single dryer can alternate the smoothness of the sides by selecting the fibers on the layer. That is, the fiber and the method of forming the layer can be selected to make the surface of the cover surface softer and prevent the softening effect of the single drying cylinder, and the smoothness can be balanced by this method. In order to produce a high quality and generally symmetrical soft paper, one of the preferred single-layer items is composed of at least three layers combined with a drying step, resulting in two sides that are less dry than Yang Qi's paper machine. Therefore, if drying, at least part of the drying is done by air-drying (TAD), it can produce a low, $ Zhang ruler thin Chinese national standard ^ ---- (Please read the precautions on the back before filling in this P.)
