Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology, and in particular to a method and system for traceability management of nonwoven fabric production quality. Background Technology

[0002] Nonwoven fabrics are nonwoven materials used in industrial production, such as spunbond, meltblown, needle-punched, spunlace, and composite specialty nonwoven fabrics. Primary nonwoven products refer to materials directly formed through processes such as fiber web formation and bonding, excluding various products that have undergone deep processing such as lamination, coating, and molding. Improving the warehousing and transshipment capabilities of nonwoven fabric wholesale markets is crucial. Support should be provided for upgrading and transforming the warehousing and logistics infrastructure of nonwoven fabric wholesale markets in distribution and sales areas. The construction of standardized warehouses and centralized distribution centers should be encouraged, and energy-saving, efficient, and environmentally friendly warehousing systems should be promoted. Functions such as logistics distribution, processing and packaging, and quality control should be improved to enhance the warehousing and transshipment service capabilities of mainstream distribution channels.

[0003] The traceability of nonwoven fabric quality and safety is challenging, yet it is widely used in numerous fields such as medical care, hygiene, and protection, and is inseparable from people's daily lives. Therefore, it is necessary to leverage modern information technology to implement strict supervision at every stage of the nonwoven fabric distribution process, from raw material testing to finished product delivery. This is crucial to ensure the quality and safety of nonwoven fabrics, achieving orderly and traceable processes at each stage. This would create a comprehensive, multi-layered regulatory system encompassing quality testing, warehousing management, and logistics distribution, enabling relevant users to trace the final product and effectively monitor material safety and the entire distribution process. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to propose a method and system for traceability management of nonwoven fabric production quality, thereby solving the current problem of the difficulty in tracing the origin of nonwoven fabrics.

[0005] To achieve this objective, the present invention adopts the following technical solution: a nonwoven fabric production quality traceability management system, comprising: a raw material warehousing module, a fabric spinning module, a processing module, and a database platform; The raw material warehousing module is used to receive production raw materials and generate a unique first traceability code based on the warehousing time of the production raw materials, and upload the first traceability code to the database platform; The fabric spinning module is used to place the production raw materials on the fabric spinning machine for processing, update the first traceability code based on the fabric spinning machine, obtain the second traceability code, paste the second traceability code on the non-woven fabric and upload it to the database platform. The processing module is used to place the non-woven fabric on the processing equipment for processing, update the second traceability code, obtain the third traceability code, and upload the third traceability code to the database platform.

[0006] Preferably, the raw material warehousing module includes a replacement submodule and a generation submodule; The replacement submodule is used to replace the raw material label with an internal label; The generation submodule is used to generate a unique first traceability code using the raw material entry time and the first serial number.

[0007] Preferably, the fabric spinning module further includes an identification card module, which generates an identification code for each spun fabric to record the material batch number, name, quantity, and specifications, and generates a second traceability code using the identification code, the first traceability code, and the number of the fabric spinning machine.

[0008] Preferably, the processing module includes a punching sub-module and a folding packaging sub-module; When punching nonwoven fabric, the punching submodule updates the second traceability code, and after punching is completed, it generates the first subcode based on the second traceability code, processing completion time, second serial number and production employee ID. The folding packaging submodule is used to fold the non-woven fabric and update the first subcode. After folding, a third traceability code is generated based on the first subcode, the folding completion time, the third serial number, and the folding group number.

[0009] Preferably, it also includes a finished product warehousing module; the finished product warehousing module is used to update the third traceability code and detect whether there is a duplicate third traceability code. If not, the third traceability code is updated based on the warehousing batch number, product name, specifications, and quantity information to obtain the final traceability code, and the final traceability code is uploaded to the data platform.

[0010] A method for traceability management of nonwoven fabric production quality, applied to the aforementioned nonwoven fabric production quality traceability management system, includes the following steps: Step S1: Receive production raw materials and generate a unique first traceability code based on the raw materials' entry time into the warehouse, and upload the first traceability code to the database platform; Step S2: Place the raw materials on the spinning machine for processing, update the first traceability code based on the spinning machine, obtain the second traceability code, paste the second traceability code on the non-woven fabric and upload it to the database platform; Step S3: Place the non-woven fabric in the processing equipment for processing, update the second traceability code, obtain the third traceability code, and upload the third traceability code to the database platform.

[0011] Preferably, the steps in step S1 are as follows: Replace the raw material labels with internal labels; A unique first traceability code is generated using the raw material's entry time and first serial number.

[0012] Preferably, the steps in step S2 are as follows: For each woven fabric, an identification code is generated to record the material batch number, name, quantity, and specifications. A second traceability code is then generated using the identification code, the first traceability code, and the number of the spinning machine.

[0013] Preferably, the steps in step S3 are as follows: when the non-woven fabric is punched, the second traceability code is updated, and after the punching is completed, the first sub-code is generated based on the second traceability code, the processing completion time, the second serial number, and the production employee's employee number; The nonwoven fabric is folded and the first sub-code is updated. After folding, the third traceability code is generated based on the first sub-code, the folding completion time, the third serial number, and the folding group number.

[0014] Preferably, the method also includes step S4: detecting whether there is a duplicate third traceability code. If not, the third traceability code is updated based on the batch number, product name, specifications, and quantity information to obtain the final traceability code, and the final traceability code is uploaded to the data platform.

[0015] One of the above technical solutions has the following advantages or beneficial effects: The mechanism of independent coding and verification at each stage in this invention acts as a strict information checkpoint for material flow, ensuring the continuity and integrity of the traceability chain and effectively preventing information gaps. Simultaneously, this "one code per link, responsibility assigned to each position" design can accurately define the responsibility boundaries of each production stage, enabling the identification of the root cause of any quality issues.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1-2 As shown, a nonwoven fabric production quality traceability management system includes the following: a raw material warehousing module, a fabric spinning module, a processing module (including punching, folding, and other processing), a finished product warehousing module, and a database platform; The raw material warehousing module is used to receive production raw materials and generate a unique first traceability code based on the warehousing time of the production raw materials, and upload the first traceability code to the database platform; The fabric spinning module is used to place the production raw materials on the fabric spinning machine for processing, update the first traceability code based on the fabric spinning machine, obtain the second traceability code, paste the second traceability code on the non-woven fabric and upload it to the database platform. The processing module is used to place the non-woven fabric on the processing equipment for processing, update the second traceability code, obtain the third traceability code, and upload the third traceability code to the database platform.

[0022] The finished product warehousing module is used to detect whether there are duplicate third traceability codes. If not, the third traceability code is updated based on the warehousing batch number, product name, specifications, and quantity information to obtain the final traceability code, which is then uploaded to the data platform.

[0023] To achieve quality monitoring and traceability throughout the entire lifecycle of nonwoven fabric products, this invention integrates four core stages: raw material warehousing, spinning, processing, and finished product warehousing, all managed and coordinated by a central database platform. First, when raw materials arrive, the raw material warehousing module generates a unique "first traceability code" based on the warehousing time and synchronizes this information to the database, establishing the traceable origin of the product. Next, the raw materials enter the spinning module. At this stage, operators must use the spinning module to obtain the first traceability code on the raw materials before starting the spinning equipment for processing. After processing, the system dynamically updates this traceability information, generating a "second traceability code" representing the semi-finished product and uploading it, thus successfully converting the raw material into a primary product (nonwoven fabric). Following this, in the processing module, by updating and verifying the second traceability code, the nonwoven fabric enters the deep processing stage. Upon completion, a "third traceability code" is generated, marking a further transformation of the product form. Finally, the finished product warehousing module performs a critical verification step, updates the third traceability code to ensure its uniqueness, and after confirming that there are no errors, it integrates the final information such as the warehousing batch number and product specifications to generate a "final traceability code" that carries the entire production history, thus completing the archiving of product information.

[0024] The mechanism of independent coding and verification at each stage in this invention acts like a strict information checkpoint for material flow, ensuring the continuity and integrity of the traceability chain and effectively preventing information gaps. Simultaneously, this "one code per link, responsibility assigned to each position" design accurately defines the boundaries of responsibility at each production stage, enabling the identification of the root cause of any quality issues.

[0025] Preferably, the raw material warehousing module includes a replacement submodule and a generation submodule; The replacement submodule is used to replace the raw material label with an internal label; The generation submodule is used to generate a unique first traceability code using the raw material entry time and the first serial number.

[0026] The following example illustrates this: Assume a batch of polypropylene (PP) raw materials is delivered to a nonwoven fabric production plant by supplier "Company A". The raw material packaging has an original label provided by the supplier, indicating its batch number, specifications, and other information. At this point, the replacement submodule begins to work: Warehouse management personnel use a PDA device to update the original label. After the system records the supplier information, the operator removes the original label and replaces it with an internal label specified by the system, which is printed with an internal code and a QR code. Immediately afterwards, the generation submodule is automatically triggered: The system obtains the time point of "raw material warehousing" (e.g., January 1, 25th year) and combines it with the "first serial number" automatically assigned by the system (e.g., 25001). The raw material is processed using the rule of "last 2 digits of the year + 3 digits of the serial number" to generate a unique first traceability code (its form may be "25001"). This code is immediately associated with the internal label, and all information—including the supplier's original data, internal code, and first traceability code—is uploaded to the central database platform for permanent storage.

[0027] Because label formats and information specifications vary widely among different suppliers, direct use would pose significant challenges to subsequent automated updates and data parsing. Replacing these labels with standardized internal tags via a replacement submodule is equivalent to issuing "internal ID cards" to all incoming raw materials, ensuring smooth and efficient information retrieval throughout the entire internal production flow. Using internally generated traceability codes, rather than relying on supplier codes, means that the company has sovereignty over its traceability data from the moment raw materials enter the warehouse. This eliminates the risk of the traceability chain breaking at its source due to unclear, non-unique, or altered external codes.

[0028] Preferably, the fabric spinning module further includes an identification card module, which generates an identification code for each spun fabric to record the material batch number, name, quantity, and specifications, and generates a second traceability code using the identification code, the first traceability code, and the number of the fabric spinning machine.

[0029] When a batch of raw materials bearing the first traceability code is transported to the textile workshop, the operators first obtain this first traceability code to authorize the textile machine to start production. The raw materials are processed into wide rolls of nonwoven fabric through meltblown and spunbond processes. During this process, the identification card module dynamically generates a unique identification code for each completed fabric (a specific production batch unit). This identification code is not a simple serial number, but a key set of data specifically used to record the core identity information of this fabric, including its material batch number, name, quantity, and specifications (e.g., material name: PP; basis weight: 25gsm; width: 1.6m; length: 3000m). Subsequently, the system merges this information-rich identification code, the first traceability code from the raw materials, and the equipment number of the textile machine responsible for production to generate a new, information-connecting second traceability code. This new second traceability code is immediately assigned to the fabric and uploaded to the data platform along with all detailed data.

[0030] This invention strongly binds production elements (specific machines) to product identity. By writing the "textile machine number" into a second traceability code, if product performance deviations occur in the future (such as uniformity issues), the problem can be instantly pinpointed to the specific production equipment, greatly facilitating equipment maintenance and the determination of process responsibility.

[0031] Preferably, the processing module includes a punch press sub-module; When punching nonwoven fabric, the punching submodule obtains the second traceability code, and after punching is completed, it generates the first subcode based on the second traceability code, the processing completion time, the second serial number, and the production employee's ID.

[0032] When a roll of nonwoven fabric bearing a second traceability code is transported to the processing workshop, operators load it onto the punching machine. Before the official punching begins, the punching submodule is activated: operators use an update gun to read the second traceability code on the roll; after system verification, the punching machine is authorized to start working. The entire roll of nonwoven fabric is cut into thousands of specific shape units through high-speed punching. After this processing is completed, the punching submodule does not simply reuse the old traceability code, but dynamically generates a new "first subcode." The generation of this new code integrates three key pieces of information: its origin is the second traceability code from the semi-finished product; its identification is the precise time of completion of this processing (e.g., 2023-10-27, Machine No. 1 production); and its serial identifier is the second serial number assigned by the system to this processing batch (e.g., 00001).

[0033] When a complete roll of fabric is cut into countless smaller pieces, the original management unit of "each piece of fabric" becomes too coarse. Generating new sub-codes for each processed product allows for traceable management down to the "production batch of each stamping operation," perfectly matching changes in the material's physical state. Furthermore, by adding production employee IDs, when processing problems arise, the corresponding employee can be traced or held accountable.

[0034] Preferably, the processing module also includes a folding packaging sub-module; The folding packaging submodule is used to update the first subcode and fold the non-woven fabric. After folding, a third traceability code is generated based on the first subcode, the folding completion time, the third serial number, and the folding group number.

[0035] When a roll of nonwoven fabric is cut into numerous individual pieces during the punching process, the punching submodule generates a first sub-code identifying the batch. These individual pieces are then gathered onto the folding and packaging line. At this point, the folding and packaging submodule begins operation: operators or automated sensors first update the first sub-code on the individual piece or batch container. After system verification, the folding and packaging machines are authorized to start. The nonwoven fabric pieces are precisely folded by the equipment and then packed into bags or boxes. At the moment the folding and packaging actions are completed, this submodule does not directly use the first sub-code but dynamically generates a completely new "third traceability code." This new code integrates three key pieces of information: its direct source is the first sub-code; its packaging completion timestamp is the folding and packaging completion time (e.g., 2023-10-27, Group 1 production); and its sequence identifier is the third serial number assigned by the system to this packaging operation (e.g., 00001). This is how the third traceability code is generated.

[0036] The process from "large roll" to "loose sheet" is a physical division, while the process from "loose sheet" to "finished product packaging" is an assembly and encapsulation; the two are fundamentally different. Establishing independent identifiers for each stage allows for precise matching of traceability granularity to every change in physical and logical state. Secondly, this establishes a clear "parent-child" traceability relationship within the complex processing flow. The second traceability code (roll material) is the parent of the first child code (loose sheet batch), and the first child code is the parent of the third traceability code (finished product packaging). This hierarchical structure enables traceability both top-down (e.g., tracing which products a roll of material ultimately became) and bottom-up (e.g., tracing which stamping and roll of material a package of products came from), achieving bidirectional and precise traceability capabilities.

[0037] A method for traceability management of nonwoven fabric production quality, applied to the aforementioned nonwoven fabric production quality traceability management system, includes the following steps: Step S1: Receive production raw materials and generate a unique first traceability code based on the raw materials' entry time into the warehouse, and upload the first traceability code to the database platform; Step S2: Place the raw materials on the spinning machine for processing, update the first traceability code based on the spinning machine, obtain the second traceability code, paste the second traceability code on the non-woven fabric and upload it to the database platform; Step S3: Place the non-woven fabric in the processing equipment for processing, update the second traceability code, obtain the third traceability code, and upload the third traceability code to the database platform.

[0038] Preferably, the steps in step S1 are as follows: Replace the raw material labels with internal labels; A unique first traceability code is generated using the raw material's entry time and first serial number.

[0039] Preferably, the steps in step S2 are as follows: For each woven fabric, an identification code is generated to record the material batch number, name, quantity, and specifications. A second traceability code is then generated using the identification code, the first traceability code, and the number of the spinning machine.

[0040] Preferably, the steps in step S3 are as follows: when the non-woven fabric is punched, the second traceability code is updated, and after the punching is completed, the first sub-code is generated based on the second traceability code, the processing completion time, the second serial number, and the production employee's employee number; The nonwoven fabric is folded and the first sub-code is updated. After folding, the third traceability code is generated based on the first sub-code, the folding completion time, the third serial number, and the folding group number.

[0041] Preferably, the method also includes step S4: detecting whether there is a duplicate third traceability code. If not, the third traceability code is updated based on the batch number, product name, specifications, and quantity information to obtain the final traceability code, and the final traceability code is uploaded to the data platform.
