Description

Technical Field

[0001] The invention belongs to the field of fabric production, and more specifically, relates to a fabric whose appearance and function can be changed at will, and a production method. Background Art

[0002] At present, most fabrics on the market adopt fixed designs, colors and functions. Once produced, their appearance and performance cannot be changed. This uniformity and fixity limits the application scope of fabrics and the personalized needs of consumers. With the development of science and technology and the diversification of consumer needs, higher requirements are placed on the functionality and scalability of fabrics.

[0003] In the existing fabric production process, there is usually a lack of consideration for the functional expandability of fabrics. For example, some fabrics may only have basic wearing or decorative functions, and cannot be added or changed at will according to user needs. In addition, the color and pattern of the fabric are usually fixed during the production process, which is difficult to change or upgrade later.

[0004] Therefore, we proposed an innovative fabric production method. The extensible fabric not only meets consumers' demand for personalization and diversification, but also brings new development opportunities to the fabric industry. It can be used not only in clothing, home furnishing and other fields, but also in industry, medical treatment, military industry and other fields, with broad market prospects and application potential. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a fabric and a production method whose appearance and function can be changed at will, so as to produce a fabric with a magnetic adsorption function. Users can match it with other decorative accessories or functional products with magnetic or magnetic-attracting properties according to personal preferences or actual needs, so that decorations or functional accessories can be added and changed at any position on the fabric at will, thereby realizing the free transformation of the appearance and function of the fabric.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A fabric whose appearance and function can be changed at will, and a production method, comprising the following steps:

[0008] S1. Select an unmagnetized magnet with a thickness range of 1mm-30mm and a width of 1mm-100mm;

[0009] S2. Customize the pressing mold according to the magnet matrix arrangement requirements and magnet size, and adjust the parameters to meet the requirements of the front and back effects after the base fabric is hot-pressed and laminated;

[0010] S3, using hot pressing to compound the magnet and the base fabric;

[0011] S4. Cut the composite fabric according to the needs, and then use a magnetizing machine to magnetize the magnets in the fabric to activate its magnetism. Through the magnetic attraction of the magnet, the fabric can be arbitrarily adsorbed and combined with decorations or products with magnetic attraction or magnetism to achieve arbitrary changes in appearance and function.

[0012] Preferably, in step S2, the design of the mold needs to ensure that the magnets can be accurately placed in a predetermined arrangement, and the material and structure of the mold need to be able to withstand the temperature and pressure during the hot pressing and compounding process; it is also necessary to consider how to reduce the mutual repulsion between the magnets, and it may be necessary to use magnetic glue to bond the pre-magnetized magnet segments together and use the mold to clamp them during bonding.

[0013] Preferably, in step S3, after the magnet and the base fabric are compositely formed, a test is required, specifically:

[0014] Detect the uniformity of the magnetic field. After hot pressing and composite molding, use a Gauss meter and other equipment to detect the magnetic field distribution after the fabric and magnet are composited to ensure its uniformity and consistency, which helps to discover potential magnetic field unevenness problems and adjust the mold design in time;

[0015] Check the bonding strength and perform strength tests on the bonding areas between the fabric and the magnet to ensure that they will not separate during subsequent use;

[0016] Evaluate the effects of the front and back sides of the fabric, compare the appearance and texture of the fabric before and after lamination, ensure that the lamination process does not cause obvious damage or deformation to the fabric, and at the same time, evaluate whether the effects of the front and back sides of the fabric meet the expected standards through visual inspection.

[0017] Preferably, the detection of magnetic field uniformity is specifically:

[0018] 1) Calibrate the Gaussmeter equipment and prepare the composite sample of fabric and magnet to be tested to ensure that the sample surface is clean and free of impurities;

[0019] 2) Determine the position of the measuring points according to the arrangement of the magnet matrix and the specific structure of the fabric, and the measuring points are evenly distributed on the entire composite fabric to fully reflect the distribution of the magnetic field;

[0020] 3) Place the probe of the Gaussmeter perpendicular to the surface of the fabric and gently touch the measuring point, read and record the magnetic field strength value displayed by the Gaussmeter, measure the magnetic field components in different directions, adjust the direction of the probe, and measure the magnetic field strength in the X, Y, and Z axis directions respectively;

[0021] 4) Analyze the uniformity and consistency of the magnetic field distribution to determine whether it meets the preset standards or requirements. Based on the analysis results of the magnetic field distribution, evaluate whether the magnetic field performance of the composite fabric meets expectations.

[0022] Preferably, the checking of the bonding strength is specifically:

[0023] Install the dried sample into the fixture of the tensile testing machine to ensure the flatness and stability of the sample.

[0024] Set the tensile testing machine's tensile speed to 100 mm / min and the preload to 1 N;

[0025] Calculate the bonding strength and record the tensile force and peeling distance of each sample at the same time. The bonding strength expression is:

[0026]

[0027] Among them, maximum peeling force: the maximum force value recorded during the peeling process.

[0028] Preferably, the magnet spacing of the magnet matrix is ​​determined according to the size and arrangement requirements of the magnets, and the size of the mold should be determined based on the size of the fabric and the overall size of the magnet matrix, and the expression is:

[0029] Mold width = fabric width + 2 × magnet radius + allowance;

[0030] Mold length = fabric length + 2 × magnet radius + allowance;

[0031] Among them, the allowance is to take into account the possible deformation and positioning error of the fabric during the hot pressing process;

[0032] The pressure of the hot pressing compound is calculated as follows:

[0033] Pressure = fabric elastic modulus × deformation / contact area.

[0034] Preferably, the visual inspection comprises:

[0035] 1) Defect inspection: Use visual inspection or a magnifying glass to inspect the surface of the package area by area, record the scratches, stains, bubbles, and uneven stitching found, and calculate the defect ratio. The calculation formula is:

[0036]

[0037] If the defective area accounts for more than 3%, it is judged as a defective product and will be returned for repair or scrapped.

[0038] 2) Color uniformity inspection: measure the color of the package at different positions and record the Lab value, where L represents brightness, a represents red-green color, and b represents yellow-blue color. Compare the color difference between the measurement points. The expression is:

[0039]

[0040] Wherein, ΔE represents the color difference value, and the threshold value of ΔE is 1.0, that is, when ΔE is greater than or equal to 1.0, it is judged as a color difference and a defective product, which is returned for repair or scrapped.

[0041] Preferably, step S4 is specifically:

[0042] In the preparation stage, ensure that the magnetizing machine, cutting tools and testing equipment are in good condition, and prepare the composite fabrics and corresponding decorative parts to be cut;

[0043] Cut fabrics, use measuring tools to accurately measure and mark the positions to be cut according to design requirements, use professional cutting equipment or tools to cut along the marked lines, ensure the edges are neat and free of burrs, and conduct preliminary inspection of the cut fabrics to ensure the size is accurate and free of defects;

[0044] During magnetization, lay the cut fabric flat on the workbench of the magnetizer to ensure that the fabric is flat and wrinkle-free. Set the current and magnetic field strength parameters of the magnetizer according to the characteristics of the magnet and the magnetization requirements. Magnetize the magnets in the fabric. During the magnetization process, monitor the operating status of the equipment to ensure that the magnetization is uniform and stable. After the magnetization is completed, use a magnetometer or related testing equipment to verify whether the magnetism of the magnet meets the expected requirements.

[0045] Preferably, after the magnetization is completed, the method further comprises:

[0046] For decoration replacement, according to the design requirements, prepare the decorative parts that need to be replaced, such as magnetic buckles, magnetic pattern patches, magnetic functional products, etc., place the decorative parts at any magnetic position on the fabric, and fix them using the adsorption force of the magnet.

[0047] The final inspection is to conduct a comprehensive inspection of the fabric after replacement to ensure that the decorative parts are firm and there is no risk of falling off, and that the overall appearance meets the design requirements. The fabric has a corresponding functional test of magnetic adsorption function to ensure normal function.

[0060] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0061] The present invention provides Figure 1-4 A method for producing fabrics whose appearance and functions can be changed at will. The fabrics are systematically combined with unmagnetized magnets and then magnetized. The new composite fabric produced has magnetic attraction function and can be combined with other magnetic products to achieve the appearance, color and function that can be expanded and changed at will.

[0062] The fabric is made of multiple layers, such as Figure 2 As shown, F is the outer layer of the fabric, D is the inner layer of the fabric, there is a G hot melt layer between F and D, there is an E magnet layer in the G hot melt layer, the magnet layer is composed of multiple magnet matrices arranged and laid out in the south pole (S pole) and north pole (N pole) directions, as shown Figure 1 shown.

[0063] like Figure 2 As shown, to produce this composite fabric, it is necessary to manufacture B pressed abrasive layer and C pressed abrasive layer (B\C can be roller-type or sheet-type according to production requirements) to heat press D / E / F / G together to form a new fabric form. The abrasive temperature and pressure parameters during composite production are adjusted according to the thickness and properties of different fabrics. Product expression: DF+E+G=H, (DF=fabric layer E=magnet layer G=hot melt layer H=new functional fabric after composite).

[0064] The production method of fabrics that can change appearance and function at will, the specific process includes:

[0065] S1, select an unmagnetized magnet; Figure 1 As shown, according to production requirements, the magnet thickness range can be 1mm-30mm, the width can be 1mm-100mm, the shape can be round or other shapes, and the unpunched magnets with national standard N28~N54 magnetic energy can be used according to product and production requirements. Each A magnet will be treated with salt spray and rust prevention, and matched with B to control the magnetic force, and C will be used to combine AB together;

[0066] S2. Customize the pressing mold according to the magnet matrix arrangement requirements and the magnet size, and adjust the parameters to meet the requirements of the front and back effects after the base fabric is hot-pressed and laminated. In step S2, the design of the mold must ensure that the magnets can be accurately placed in the predetermined arrangement, and the material and structure of the mold must be able to withstand the temperature and pressure during the hot-pressing and laminating process. It is also necessary to consider how to reduce the mutual repulsion between the magnets. It may be necessary to use magnet glue to bond the pre-magnetized magnet segments together, and use the mold to clamp them during bonding.

[0067] The magnet spacing of the magnet matrix is ​​determined according to the size and arrangement requirements of the magnets, and the size of the mold should be determined based on the size of the fabric and the overall size of the magnet matrix. The expression is:

[0068] Mold width = fabric width + 2 × magnet radius + allowance;

[0069] Mold length = fabric length + 2 × magnet radius + allowance;

[0070] Among them, the allowance is to take into account the possible deformation and positioning error of the fabric during the hot pressing process;

[0071] The pressure of the hot pressing compound is calculated as follows:

[0072] Pressure = fabric elastic modulus × deformation / contact area.

[0073] Furthermore, the pressing mold needs to be customized to match the magnet matrix arrangement. The concave position corresponds to the matrix arrangement requirements of the magnet layer and the size of the magnet. At the same time, the thickness of the composite fabric and the magnet should be considered. When customizing the mold, the matching parameters of the concave position should be adjusted to match the requirements of the hot pressing of the base fabric and the composite thick fabric to achieve the effect of the front and back sides.

[0074] S3, the magnet and the base fabric are composited by hot pressing; in step S3, after the magnet and the base fabric are composited, they need to be tested. During production, the B pressed mold layer and the C pressed mold layer (B\C can be rolled or sheet-type according to production requirements) hot press D / E / F / G together to form a new fabric form. During composite production, the mold temperature, pressure, and time parameters need to be adjusted according to the thickness and properties of different fabrics; temperature value: 50℃-300℃;

[0075] Specifically:

[0076] Detect the uniformity of the magnetic field. After hot pressing and composite molding, use a Gauss meter and other equipment to detect the magnetic field distribution after the fabric and magnet are composited to ensure its uniformity and consistency, which helps to discover potential magnetic field unevenness problems and adjust the mold design in time; the specific detection of magnetic field uniformity is:

[0077] 1) Calibrate the Gaussmeter equipment and prepare the composite sample of fabric and magnet to be tested to ensure that the sample surface is clean and free of impurities;

[0078] 2) Determine the position of the measuring points according to the arrangement of the magnet matrix and the specific structure of the fabric, and the measuring points are evenly distributed on the entire composite fabric to fully reflect the distribution of the magnetic field;

[0079] 3) Place the probe of the Gaussmeter perpendicular to the surface of the fabric and gently touch the measuring point, read and record the magnetic field strength value displayed by the Gaussmeter, measure the magnetic field components in different directions, adjust the direction of the probe, and measure the magnetic field strength in the X, Y, and Z axis directions respectively;

[0080] 4) Analyze the uniformity and consistency of the magnetic field distribution to determine whether it meets the preset standards or requirements. Based on the analysis results of the magnetic field distribution, evaluate whether the magnetic field performance of the composite fabric meets expectations;

[0081] Check the bonding strength and perform strength test on the bonding part between the fabric and the magnet to ensure that they will not separate during subsequent use; the specific bonding strength test is as follows:

[0082] Install the dried sample into the fixture of the tensile testing machine to ensure the flatness and stability of the sample.

[0083] Set the tensile testing machine's tensile speed to 100 mm / min and the preload to 1 N;

[0084] Calculate the bonding strength and record the tensile force and peeling distance of each sample at the same time. The bonding strength expression is:

[0085]

[0086] Among them, maximum peeling force: the maximum force value recorded during the peeling process;

[0087] Evaluate the effects of the front and back of the fabric, compare the appearance and texture of the fabric before and after lamination, ensure that the lamination process does not cause obvious damage or deformation to the fabric, and at the same time, evaluate whether the effects of the front and back of the fabric meet the expected standards through visual inspection; the visual inspection includes:

[0088] 1) Defect inspection: Use visual inspection or a magnifying glass to inspect the surface of the package area by area, record the scratches, stains, bubbles, and uneven stitching found, and calculate the defect ratio. The calculation formula is:

[0089]

[0090] If the defective area accounts for more than 3%, it is judged as a defective product and will be returned for repair or scrapped.

[0091] For example, during a fabric production process, we used visual inspection and a magnifying glass to conduct a detailed defect inspection on a batch of composite fabrics. During the inspection, we found some scratches, stains, and uneven stitching. In order to assess the severity of these defects, we recorded the area of ​​each defect and calculated the defect ratio.

[0092] Suppose we inspected 100 square meters of fabric and found 5 square meters of defects. Then, the defect ratio is:

[0093]

[0094] Conclusion: Since 5% is greater than the threshold of 3%, we determine that this batch of fabrics is defective and needs to be repaired or scrapped.

[0095] 2) Color uniformity inspection: measure the color of the package at different positions and record the Lab value, where L represents brightness, a represents red-green color, and b represents yellow-blue color. Compare the color difference between the measurement points. The expression is:

[0096]

[0097] In the formula, ΔE represents the color difference value, and the threshold value of ΔE is 1.0, that is, ΔE greater than or equal to 1.0 is considered a color difference and a defective product is returned for repair or scrapped;

[0098] For example, in another production, we tested the color uniformity of the fabric. We measured the color of the fabric at different locations and recorded the Lab value. The Lab value is a color space model, where L represents brightness, a represents red-green, and b represents yellow-blue.

[0099] Suppose we measured the color of the fabric at three different locations and obtained the following Lab values:

[0100] Position 1: L1=70, a1=10, b1=5;

[0101] Position 2: L2=72, a2=9, b2=6;

[0102] Position 3: L3=68, a9=11, b3=4;

[0103] Calculate the color difference ΔE between each measurement point:

[0104]

[0105] For the color difference between position 1 and position 2:

[0106]

[0107] Similarly, calculate the color difference between other positions. If any color difference ΔE is greater than or equal to 1.0, the fabric is judged to be a color difference defective product and needs to be repaired or scrapped.

[0108] S4. Cut the composite fabric according to the needs, and then use a magnetizing machine to magnetize the magnets in the fabric to activate its magnetism. By the magnetic attraction of the magnets, the decorative parts on the fabric are replaced to achieve the change of appearance and function at will;

[0109] Step S4 is specifically as follows:

[0110] In the preparation stage, ensure that the magnetizing machine, cutting tools and testing equipment are in good condition, and prepare the composite fabrics and corresponding decorative parts to be cut;

[0111] Cut the fabrics, according to the design requirements, use measuring tools to accurately measure and mark the positions to be cut, use professional cutting equipment or tools, cut along the marked lines, ensure the edges are neat and frizz-free, and conduct preliminary inspection of the cut fabrics to ensure the size is accurate and flawless;

[0112] Magnetization treatment: put the cut fabric into the magnetizer, set the current and magnetic field strength parameters of the magnetizer according to the characteristics of the magnet and the magnetization requirements; magnetize the magnets in the fabric, monitor the operating status of the equipment during the magnetization process to ensure that the magnetization is uniform and stable. After the magnetization is completed, use a magnetometer or related testing equipment to verify whether the magnetism of the magnet meets the expected requirements;

[0113] After the magnetization is completed, the method further comprises:

[0114] For decoration replacement, prepare the decorative parts that need to be replaced according to the design requirements, such as magnetic buckles and pattern patches, place the decorative parts at any position on the fabric, and fix them using the adsorption force of magnets.

[0115] The final inspection is to conduct a comprehensive inspection of the fabric after replacement to ensure that the decorative parts are firm and there is no risk of falling off, and that the overall appearance meets the design requirements. The fabric has a corresponding functional test of magnetic adsorption function to ensure normal function.

[0116] This embodiment also proposes a fabric whose appearance and function can be changed at will. The fabric is made by the above-mentioned method for producing a fabric whose appearance and function can be changed at will. The fabric is made of a fiber fabric base cloth, a magnet and a hot melt adhesive. The fiber fabric base cloth is made of nylon, polyester, nylon and linen. Nylon, polyester, nylon and linen are made into thin strands respectively, and then a group of nylon thin strands, a group of polyester thin strands, a group of nylon thin strands and a group of linen thin strands are made into thick strands, and the thick strands are woven into fabric to make a fabric for use. The base fabric of the fabric whose appearance and function can be changed at will, wherein nylon accounts for 40%-60% of the thick strands, polyester accounts for 27%-33%, nylon accounts for 15%-28%, and linen accounts for 5%-12%. The nylon fine strands in the thick strands are made of high-strength, low-elasticity nylon material to improve the wear resistance and tear resistance of the base fabric; the polyester fine strands are made of polyester fibers with wrinkle resistance and quick-drying properties to enhance the shape retention and comfort of the fabric; the nylon fine strands use soft and glossy nylon yarns.

The method for producing a fabric with arbitrarily changeable appearance and function according to claim 3, characterized in that: The visual inspection includes: 1) Defect inspection: Use visual inspection or a magnifying glass to inspect the surface of the package area by area, record the scratches, stains, bubbles, and uneven stitching found, and calculate the defect ratio. The calculation formula is: If the defective area accounts for more than 3%, it is judged as a defective product and will be returned for repair or scrapped. 2) Color uniformity check: measure the color of the fabric at different positions and record the Lab value, where L represents brightness, a represents red-green color, and b represents yellow-blue color. Compare the color difference between the measurement points. The expression is: Wherein, ΔE represents the color difference value, and the threshold value of ΔE is 1.0, that is, when ΔE is greater than or equal to 1.0, it is judged as a color difference and a defective product, which is returned for repair or scrapped.
