Description

Technical Field

[0001] This invention relates to the field of garment manufacturing and design technology, specifically to a peelable garment pattern-making composite material and its preparation method. Background Technology

[0002] In the process of clothing design and production, pattern making (or pattern drafting) is a crucial step. Designers need to transform the two-dimensional planar pattern on the design drawings into a template that can be used for actual cutting. Traditional clothing pattern making methods usually involve laying out pattern paper (such as kraft paper), covering it with muslin (or other fabrics), and then cutting according to the pattern. During this process, to ensure that the fabric and pattern paper do not shift relative to each other during cutting, it is usually necessary to fix them by hand with pins or temporarily glue them with ordinary tape. In contrast, in the three-dimensional draping method, the maker starts by draping the fabric directly onto a mannequin (dress), and through continuous fixing, cutting, and adjustment, forms a three-dimensional muslin sample garment (Toilet). Subsequently, the three-dimensional sample garment needs to be disassembled into planar segments and then transferred to paper pattern sheets to create the final paper pattern.

[0003] However, these traditional methods have many drawbacks: (1) Inefficient and impaired precision: Using pins for fixing is not only cumbersome and inefficient, but also the fabric and paper may still slip slightly during the cutting process, affecting the cutting precision and causing the final garment to deviate from the design pattern.

[0004] (2) Damage to fabric and paper: Pins will leave pinholes on the fabric, causing irreversible damage to some precious or thin fabrics. Using ordinary tape for bonding can easily tear the pattern paper or pull out the fabric fibers when peeled off, and the tape will leave hard-to-clean residue on the fabric and paper, contaminating the materials and affecting the reuse of the pattern paper and the subsequent processing of the fabric.

[0005] (3) Inability to achieve stable bonding and easy peeling: Some adhesive products on the market attempt to solve the fixation problem, but they often fail to meet two core requirements at the same time: on the one hand, they must provide sufficient and uniform adhesive force during the cutting process to ensure that the materials are tightly bonded and stable without shifting; on the other hand, they must be easy and clean to peel off after adjustment or cutting is completed, and the peeling process must not affect the reuse of the fabric and pattern paper. Ordinary strong adhesives are difficult to peel off and will inevitably leave adhesive residue, while products with too weak an adhesiveness cannot play an effective fixing role. Summary of the Invention

[0006] The purpose of this invention is to provide a peelable garment pattern-making composite material and its preparation method. By optimizing the adhesive formulation and structural design, a reliable temporary composite of fabric and paper is achieved. Peeling is easy and without damage, making it suitable for garment pattern making processes with frequent modifications, while reducing costs and being environmentally friendly.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a peelable garment pattern-making composite material and its preparation method, comprising a fabric layer, an adhesive layer, a paper layer, and a release coating in a top-to-bottom order. The fabric layer, as the upper layer of the composite material, is typically made of textile material and is used to simulate the actual characteristics of garment fabrics, allowing for accurate evaluation of cutting and bonding effects during the pattern-making process. The adhesive layer is tightly attached below the fabric layer, its core function being to provide temporary adhesion, enabling a firm bond between the fabric and paper layers, while allowing for easy separation when needed. The paper layer, located below the adhesive layer, serves as a supporting base, providing a stable plane for garment pattern making, facilitating the drawing of pattern lines or cutting operations. The release coating is applied to the top of the paper layer, its main function being to protect the paper layer from damage during peeling, such as preventing paper fibers from being pulled up or torn, thereby ensuring the integrity and reusability of the pattern-making material. This layered design makes composite materials both practical and convenient in clothing design and prototyping. Designers can first draw the pattern on a paper layer, then fix the fabric layer with an adhesive layer for three-dimensional verification. After completion, the fabric layer can be easily peeled off without leaving any adhesive residue, improving pattern making efficiency and quality.

[0008] Furthermore, the specific coating method for the adhesive layer involves using double-sided adhesive applied in a dotted pattern, with each dot approximately 0.5 cm in diameter, arranged in a grid or dotted pattern with gaps. This design is not arbitrary but rather aims to achieve a balance between adhesive strength and peelability. The dotted coating reduces the total amount of adhesive used, avoiding over-adhesion caused by overall coverage, allowing the fabric and paper layers to maintain a certain degree of flexibility after lamination. The intentionally left gaps in the grid or dotted arrangement form natural peel initiation edges, allowing users to easily separate the layers without tools or excessive force, thus reducing the risk of material damage. The dot diameter is controlled at approximately 0.5 cm, ensuring sufficient bonding area while preventing excessively large dot units from affecting peel smoothness. This coating method is particularly suitable for garment pattern making, where repeated pasting and peeling are often required. The dotted layout provides controllable adhesive force, ensuring the composite material maintains stable performance even after multiple uses.

[0009] Furthermore, regarding the specific material parameters of the fabric and paper layers, the fabric layer is made of 120gsm cotton greige fabric, while the paper layer uses 60-90gsm pattern-making paper. The 120gsm cotton greige fabric has a moderate weight and thickness, effectively simulating the texture and drape of common garment fabrics, making pattern-making tests closer to the actual garment effect. The greige characteristics of cotton ensure a smooth surface without dye interference, facilitating designers' observation of pattern lines or marking. The 60-90gsm pattern-making paper for the paper layer is specially selected to meet cutting and strength requirements; its lighter weight makes the paper easy to bend and cut, while sufficient strength prevents tearing during processing. Pattern-making paper typically has a good surface smoothness, facilitating accurate pattern drawing with pencils or professional pens, while its durability supports multiple modifications and reuse. This material combination balances practicality and economy; the fabric layer provides a realistic fabric experience, and the paper layer ensures the accuracy of the pattern design, thereby improving the overall efficiency of garment sampling.

[0010] Furthermore, the release coating, which can be in the form of a release film or a release coating layer, is applied to the top of the paper layer. The main function of the release coating is to enhance the surface properties of the paper layer, preventing tearing or fiber pulling when the adhesive layer is peeled off. During the use of composite materials, when users separate the fabric and paper layers, the adhesive may exert tension on the paper surface. Without the protection of the release coating, the paper layer is easily damaged, affecting the integrity and repeatability of the pattern. The release coating reduces the direct contact area between the adhesive and the paper by providing a smooth, low-surface-energy barrier, making the peeling process smoother. In addition, the release coating also improves the abrasion resistance and moisture resistance of the paper layer, extending the service life of the composite material. This design ensures that the pattern-making material remains clean after multiple peels, supporting repeated adjustments and optimizations in clothing design.

[0011] Furthermore, the adhesive layer is an acrylic-based hot-melt pressure-sensitive adhesive, which is transparent or slightly milky white in appearance and has low-tack, peelable properties. The choice of acrylic-based hot-melt pressure-sensitive adhesive is based on its excellent performance balance, such as good initial tack and controllable peel strength, allowing the composite material to bond firmly after application and easily separate when needed. The transparent or slightly milky white appearance ensures that the adhesive layer does not interfere with the visual perception of the fabric or paper layers, allowing designers to clearly observe pattern details. The low-tack property is crucial, as it leaves no residue after peeling, avoiding contamination of the material surface. The preparation of hot-melt pressure-sensitive adhesives typically involves heating and melting before coating, followed by cooling to form an adhesive layer; this process is simple and environmentally friendly. In garment pattern making, this adhesive provides reliable temporary bonding, supports rapid prototyping and modifications, while the peelable property reduces material waste, aligning with sustainable design principles.

[0012] Furthermore, the adhesive layer composition, by weight percentage, comprises 60-70% acrylate copolymer, 0-10% tackifying resin, 0-10% plasticizer, 0.5-1% antioxidant or UV stabilizer, 0.5-1% wetting agent or leveling agent, and 0-10% solvent or carrier. The acrylate copolymer, as the main component, provides the adhesive with basic tack and flexibility, enabling it to adapt to minor deformations on different surfaces. The addition of the tackifying resin adjusts the initial tack, ensuring sufficient adhesion of the composite material immediately after bonding. The plasticizer improves the adhesive's softness and low-temperature performance, preventing brittleness in cold environments. The antioxidant or UV stabilizer inhibits the aging process, reducing yellowing or performance degradation and extending material life. The wetting agent or leveling agent promotes uniform distribution of the adhesive during application, avoiding bubbles or defects. The solvent or carrier helps adjust viscosity for easier processing. This formulation design ensures the adhesive layer performs stably in garment pattern making, supporting multiple bond-peel cycles.

[0013] Furthermore, the preparation method of the composite material involves applying an adhesive layer in a dotted or grid pattern to a fabric or paper layer, then laminating it with another layer, and applying a release coating to the top of the paper layer. The coating process requires precise control; the dotted or grid pattern is achieved using specialized coating equipment to ensure uniform adhesive distribution and allowances for gaps. The lamination step is typically performed at room temperature or with slight heating, allowing the layers to bond under pressure and preventing deformation due to excessive stress. The release coating may be applied by spraying or roller coating to form a continuous film. The entire preparation method emphasizes strong bonding between the layers while maintaining a smooth surface for easy pattern making. This method is simple and efficient, suitable for large-scale production, and eliminates the need for complex processes, thus reducing costs. The final product exhibits high consistency and reliability, meeting the garment industry's requirements for pattern-making materials.

[0014] Furthermore, the adhesive layer's performance parameters are as follows: initial tack of 0.5-1.0 N / cm, peel strength of 1.0-2.5 N / 25mm, re-adhesion capability of 3-5 times, and residual adhesive ≤0.1%. The initial tack ensures sufficient adhesion upon bonding, preventing displacement or curling. The peel strength range defines the force required for separation; it must not be too high, causing tearing, nor too low, affecting adhesive stability. The 3-5 re-adhesion capability means the material supports multiple adjustments and repeated sampling, reducing waste. Residual adhesive controlled to no more than 0.1% ensures a clean surface after peeling, free of adhesive residue. These parameters collectively ensure the composite material's practicality in garment pattern making, allowing designers to confidently conduct repeated testing without worrying about material performance degradation or contamination.

[0015] Furthermore, the adhesive coating method must ensure that the fabric and paper layers remain clean after lamination, with no adhesive residue upon peeling. This requires strict control over the amount and distribution of adhesive during the coating process, such as reducing the overall adhesive volume through dotted coating to avoid overflow or seepage. A clean surface means that the composite material does not attract dust or impurities during storage and use, maintaining the clarity of the pattern drawing. No adhesive residue is a core requirement, achieved by selecting low-tack pressure-sensitive adhesives and optimizing the coating process, ensuring that both the fabric and paper layers can be directly reused or discarded after peeling without the need for cleaning. This design enhances the user experience, makes the garment pattern-making process more efficient and environmentally friendly, and meets the workflow requirements of modern design studios.

[0016] Furthermore, the functions of each component in the adhesive layer are as follows: the acrylate copolymer provides the foundation for tack and flexibility; the tackifying resin enhances initial tack; the plasticizer adjusts softness and low-temperature performance; the antioxidant or UV stabilizer prevents aging and yellowing; and the wetting agent or leveling agent improves the uniformity of the adhesive and coating performance. The acrylate copolymer, as the backbone, determines the adhesive's main properties, such as elasticity and durability. The tackifying resin enhances initial adhesion speed through intermolecular interactions, making it suitable for rapid bonding applications. The plasticizer keeps the adhesive flexible over a wide temperature range, preventing brittleness. The stabilizer component inhibits degradation caused by oxidation or UV radiation, maintaining appearance and performance. The wetting agent and leveling agent ensure smooth spread of the adhesive during coating, reducing defects. This synergistic formulation makes the adhesive layer reliable and durable in garment pattern making, supporting complex application environments.

[0017] This invention provides a peelable garment pattern-making composite material and its preparation method, which has the following beneficial effects: This peelable garment pattern-making composite material, through a specially designed adhesive layer, enables easy peeling and repeated bonding between the fabric and paper layers, greatly enhancing the flexibility and convenience of the garment pattern-making process. The adhesive layer is applied in a dotted pattern, with dots approximately 0.5 cm in diameter, arranged in a grid or dotted pattern with gaps. This design not only provides a clear peel starting edge but also reduces the overall bonding area, allowing users to easily cut and separate the two layers from the edge when adjusting the pattern, without using tools or excessive force, avoiding the tearing or deformation problems that can occur with traditional one-piece adhesive coatings. The adhesive layer has low-tack peelable properties, with an initial tack of 0.5-1.0 N / cm and a peel strength of 1.0-2.5 N / 25 mm. This moderate tack ensures a strong bond between the material layers during normal pattern-making operations, while allowing for smooth separation without leaving any adhesive residue. Furthermore, the adhesive layer supports 3-5 re-bonding cycles, meaning pattern makers can repeatedly bond and separate the material during fittings or alterations without affecting the bonding performance. This reusable pasting capability reduces material waste and allows pattern makers to experiment and adjust multiple times, making it particularly suitable for the intricate pattern making of haute couture or bespoke garments, where patterns often require repeated revisions. Overall, the design makes the pattern-making process more efficient and user-friendly, reducing operational difficulty and improving work efficiency.

[0018] This composite material features a release coating on the paper layer. This design significantly enhances the structural integrity of the paper layer during peeling, preventing tearing or fiber pulling, thus ensuring the accuracy and long-term durability of garment pattern making. The paper layer is made of 60-90gsm pattern paper, which typically has high strength and moderate thickness, suitable for cutting and drawing. However, in traditional composite structures, direct peeling can easily lead to surface damage or delamination. The release coating acts as a protective barrier, reducing the direct adhesion between the paper layer and the adhesive layer, allowing for a smooth peeling process without physical damage to the paper. The release coating can be a release film or a special coating, acting like a release agent to ensure that the adhesive layer preferentially detaches from the coating surface during separation, rather than being torn from the paper itself. This not only maintains the flatness and smoothness of the paper but also allows the pattern paper to be reused or stored as a template, extending the material's lifespan. In garment pattern making, the integrity of the paper layer is crucial because it directly affects the accurate cutting and marking of patterns; any tearing or fraying will lead to dimensional deviations or blurred lines. By applying a release coating, this composite material ensures that the paper layer remains in its original state after plate making, supporting fine operations such as pinhole marking or pen adjustments. Therefore, this not only improves plate making quality but also reduces rework caused by material damage, saving time and resources.

[0019] This composite material simplifies garment pattern making by integrating fabric, adhesive, paper, and release coating into a single structure, significantly improving efficiency and user experience. In traditional pattern making, pattern makers must handle fabric and paper separately and bond them using temporary methods (such as pinning or tape), a cumbersome and error-prone process. This composite material, however, pre-bonds each layer firmly, allowing users to draw, cut, and adjust directly on the composite, achieving a stable double-layer structure without additional steps. The adhesive layer, applied in a dotted or grid pattern, facilitates peeling and ensures overall material flexibility and breathability, making the pattern-making process more ergonomic and reducing operator fatigue. The fabric layer uses 120gsm cotton greige fabric, offering excellent hand feel and drape, while the paper layer provides support. This combination mimics the behavior of real fabric, resulting in more accurate pattern making. Furthermore, the dotted coating layout leaves gaps, preventing excessive material stiffness and allowing pattern makers to easily bend or fold the material for three-dimensional cutting. This integrated design shortens plate-making preparation time, making it particularly suitable for mass production or educational scenarios, where rapid iteration is key. Overall, the composite material streamlines the plate-making process, reduces the learning curve, and allows even beginners to quickly get started, thereby improving overall production efficiency.

[0020] This peelable design endows the composite material with high reusability and recyclability, effectively reducing material consumption and environmental pollution in the garment pattern-making industry, aligning with sustainable development principles. The adhesive layer exhibits low residue (≤0.1%) and leaves no residue on the fabric or paper layers after peeling. This means the material layers remain almost entirely intact after separation, facilitating multiple uses or recycling. For example, the paper layer can still be used as regular pattern-making paper after removal, while the fabric layer can be reused after washing, reducing the need for new material procurement. The adhesive composition includes environmentally friendly elements such as acrylate copolymers and optional biodegradable additives, reducing the risk of toxic substance release. The dot-coating method reduces adhesive usage, further minimizing resource consumption. In the garment industry, the pattern-making process often generates significant amounts of single-use waste. This composite material, through its peelable and re-attachable mechanism, extends the material's lifespan and reduces its carbon footprint. Furthermore, this design encourages users to adopt frugal habits, reducing waste at its source, making it particularly suitable for environmentally conscious brands or regions with stringent regulations. Overall, this composite material not only improves economic efficiency but also contributes to green manufacturing, demonstrating a combination of innovation and environmental protection.

[0021] The adhesive layer of this composite material is based on an acrylic-based hot-melt pressure-sensitive adhesive, and through scientific formulation optimization, it exhibits excellent anti-aging properties and performance stability, ensuring the reliability of the material during long-term storage or use. By weight percentage, the adhesive contains 60-70% acrylate copolymer to provide the tack base, supplemented with tackifying resins, plasticizers, antioxidants, UV stabilizers, wetting agents, and leveling agents. These additives work synergistically to prevent the adhesive from yellowing, becoming brittle, or experiencing performance degradation under humid, hot, or light-exposed conditions. Antioxidants and UV stabilizers effectively inhibit oxidation and UV degradation, ensuring consistent initial tack and peel strength under various environments. Wetting agents and leveling agents improve coating uniformity, avoiding localized failures caused by uneven colloid distribution. This stability makes the composite material less prone to deterioration during warehousing or transportation, suitable for global supply chain scenarios. In garment pattern making, materials often need to be stored for long periods for modifications; the stability of the adhesive prevents adhesion failure or contamination problems that may occur over time. Furthermore, consistent performance means that each batch of material exhibits predictable behavior, reducing the risk of quality fluctuations and improving the reliability of plate-making results. Overall, this effect ensures product durability and user trust, supporting long-term business operations. Attached Figure Description

Detailed Implementation

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1 This embodiment relates to a peelable composite material for garment pattern making used in high-end women's draping. In use, the pattern maker first prepares a piece of the composite material of sufficient size. Its structure, from top to bottom, consists of: a fabric layer 1 made of 120gsm cotton greige fabric; an adhesive layer 2 composed of acrylic-based hot-melt pressure-sensitive adhesive coated in a dotted grid pattern; a paper layer 4 composed of 80gsm pattern paper; and a release coating 3 applied to the top of the paper. After wrapping the dress form with the greige fabric and creating a basic shape, the pattern maker lays the composite material, with the release coating 3 facing down, on the workbench. Next, using a special pattern ruler and a pressure-sensitive pen, the clean outline of the garment's front piece is precisely drawn on the smooth surface of the paper layer 4, including key areas such as the armhole curve and side seams.

[0027] After the drawing is completed, use sharp fabric scissors to cut along the drawn outline. The scissors will cut through the fabric layer 1, adhesive layer 2, paper layer 4, and release coating 3 in one go, resulting in a neatly edged garment front panel composite component. Then, starting from one corner of the component, gently pinch a corner of the paper layer 4 with your fingers, and then smoothly and slowly peel the paper layer 4, along with the release coating 3 above it, from the fabric layer 1. Because the adhesive layer 2 has a specific low peel strength and is distributed in a dotted pattern, the peeling process is very smooth. The paper layer 4 remains intact under the protection of the release coating 3, without tearing or fiber pulling, and no adhesive residue is left on the fabric layer 1.

[0028] Finally, the pattern maker uses the clean, shape-preserving fabric layer 1 obtained after peeling off the paper pattern directly on a dress form for 3D stitching and shape verification. This method greatly simplifies the conversion process from paper pattern to muslin sample garment, improving the efficiency and accuracy of draping.

[0029] Example 2 This embodiment demonstrates the application of this composite material in the industrialized garment production process for modifying and adjusting complex pattern designs. In the sample garment production workshop, the technician receives a preliminary pattern for a coat with intricate princess seams. To verify its fit, the technician fixes the composite material paper layer 4 face up on a large cutting table. Then, the various pattern pieces of the coat are pressed onto paper layer 4 with weights, and all outlines and internal alignment marks are precisely traced with a pen.

[0030] After tracing, CNC cutters or hand scissors are used to cut along the outline to obtain composite material samples for the entire coat. The craftsman doesn't peel off the paper layer 4 of these samples immediately; instead, they are temporarily glued to the fabric used to make the sample garment using the adhesive layer 2 at the bottom, for basting and initial fitting. After fitting, it is found that the back shoulder needs to be narrowed by 0.5 cm. At this point, the craftsman can easily peel the entire composite material sample off the fabric, carefully peel off the paper layer 4, and directly mark the lines that need modification on the exposed fabric layer 1. After modification, if further verification is needed, the previously peeled paper layer 4 with the original lines can be re-aligned and glued to the modified fabric layer 1 using the adhesive layer 2 for comparison and confirmation. This reversible pasting and modification process avoids the errors and time wasted by repeated pattern tracing in traditional methods, making it particularly suitable for developing complex patterns that require multiple adjustments.

[0031] Example 3 This embodiment describes the use of this material in fashion school teaching. In a garment pattern-making course, each student is given several sheets of the composite material in A2 size. The lesson focuses on learning to draw a classic suit sleeve pattern. The teacher instructs students to first complete a sketch on ordinary drawing paper. After checking for accuracy, the composite material is then placed over the sketch for tracing. Students lay the composite material flat on a light table, with the release coating 4 facing down. Due to the release coating 4, the composite material does not stick to the light table surface. The light table light is turned on, and the lines of the suit sleeve drawn on the ordinary paper are clearly visible. Students use a pattern-making pen to accurately trace the lines on the composite material's paper layer 4.

[0032] After tracing the pattern, students use a craft knife and a steel ruler to cut along the sleeve cap curve and seam line on paper layer 4. Because paper layer 3 uses 75gsm pattern paper, it has sufficient strength and cut resistance, resulting in smooth, burr-free cut edges. After cutting, students gently peel away paper layer 4 and release coating 3, starting from the cuff, to reveal the underlying fabric layer 1. At this point, a suit sleeve component made entirely of fabric layer 1, perfectly matching the paper pattern, is presented. Students can immediately sew this fabric sleeve piece to the fabric pattern piece of the garment body, visually observing key craftsmanship effects such as sleeve cap ease and sleeve shape three-dimensionality. This method seamlessly connects planar pattern teaching with three-dimensional sewing practice, enabling students to more quickly understand the relationship between the pattern and the finished garment, resulting in significant teaching effectiveness.

[0033] Example 4 This embodiment relates to a scenario where this composite material is used to provide customers with intuitive samples in personalized custom clothing. After completing the customer's size measurements and style communication, the pattern maker in the high-end custom shop uses CAD software to draw a preliminary garment pattern, and then prints the pattern directly onto the paper layer 4 of the composite material using a large plotter. The paper layer 3 used for printing is specially treated to have good adaptability to inkjet or laser printing, producing clear lines without smudging.

[0034] After printing, the pattern maker meticulously cuts the sample pieces along the printed lines using scissors, resulting in a composite material sample that perfectly matches the client's customized style. The pattern maker then peels off the paper layer 4 of all the sample pieces, leaving only the fabric layer 1 with the adhesive layer 2. These fabric samples can be directly pasted onto a pre-fabricated fabric of similar color and thickness prepared for the client, or, with the client's consent, temporarily and carefully pasted onto the outside of their own base garment for a quick 3D silhouette and proportion fitting. Because the initial tack of the adhesive layer 2 is controlled at 0.8 N / cm, it ensures the sample is temporarily fixed while preventing damage or residue to the underlying garment when gently peeled off. This allows clients to visually see the approximate silhouette and proportions of the garment before actually cutting the expensive main fabric, and to provide feedback. This "soft sample" method enhances the experience and reliability of the customization service.

[0035] Example 5 In this embodiment of draping, an A2-sized piece of fabric is first placed directly on the human body model and shaped. During the shaping process, cutting, folding, and marking can be done directly on one side of the fabric 1. After folding a three-dimensional shape onto the human body model, it is carefully removed, and paper 4 is torn off to obtain paper pattern 4, while maintaining the original three-dimensional shape of the fabric 1. Draping is a common method in women's clothing design. Its special features are its three-dimensionality, drape, and wrapping 3D effect. Because once the fabric has been draped onto the human body model, it is difficult to remove it and flatten it because it is curved along the curves of the human body. Therefore, in this embodiment, paper 4 can be torn off directly after the draping is completed to accurately obtain a cardboard pattern.
