Description

Technical Field

[0001] The invention belongs to the technical field of yarn quality analysis and optimization, and relates to an efficient short-process yarn quality prediction analysis and optimization method. Background Art

[0002] Yarn refers to a slender body made of textile fibers after processing and spinning, and is the basic unit of textiles. It can be made of a single raw material, such as pure cotton yarn, pure wool yarn, etc., or it can be a blend of multiple fibers, such as cotton and linen blended yarn, polyester and cotton blended yarn, etc. As the raw material of textiles, the quality of yarn directly affects the production efficiency and scrap rate. High-quality yarn can reduce problems such as broken ends and skipped threads in the production process, thereby reducing production costs. Therefore, the analysis and optimization system for yarn quality plays a very important role.

[0003] In the prior art, there are also some related solutions involving the analysis of yarn quality. For example, the invention patent application for a spinning quality prediction method based on the Attention-GRU model with Chinese Patent Number 202211328257.0 uses the Attention-GRU model to aggregate and fully learn the information of the raw cotton performance indicators of the yarn, and analyze the importance of the raw cotton performance indicators at different times according to the weight size, effectively highlighting the key information of the factors affecting the yarn quality, and then outputting the predicted value of the yarn quality, thereby reducing the amount of calculation while ensuring the accuracy of the prediction and improving the prediction efficiency.

[0004] Another invention patent application with Chinese patent number 202211278000.9 is for a yarn quality prediction method based on meta-learning method. It uses the grey correlation method to analyze the weights of the input parameters affecting the yarn quality, improves the calculation speed and accuracy of the calculation results, and proposes a BiLSTM model that introduces confidence. It can deeply explore the relationship between the input parameter characteristics and the yarn quality, improve the prediction accuracy and efficiency of the model, and solve the problem of scarcity of yarn quality prediction samples based on the meta-machine learning method, thereby improving the prediction accuracy of the algorithm.

[0005] There is also an invention patent application for an intelligent optimization method and system for vortex spinning yarn preparation with Chinese patent number 202410634643.5. It fully automatically monitors the yarn production process, predicts and optimizes the yarn preparation parameters, and monitors and adjusts them in real time, thereby improving the scientificity and accuracy of decision-making, reducing ineffective operations and resource consumption in the yarn production process, and further improving the stability and predictability of the production process.

[0006] Although the above schemes have proposed some solutions to yarn quality, they still have certain limitations: on the one hand, the existing schemes mainly predict and analyze a certain type of yarn, lack the extensiveness of testing and analysis of various types of yarns, resulting in a single direction in the prediction of yarn quality, and thus unable to have a more comprehensive understanding of the performance characteristics of different yarns, and to more accurately control the quality during its production process, reduce the defective rate, and improve product quality.

[0007] On the other hand, the existing solutions ignore the monitoring and analysis of textile equipment in the yarn production process, and thus cannot eliminate the impact of yarn textile equipment on its quality, and thus cannot more accurately discover the root causes of yarn quality problems, and cannot timely adjust and control these factors during its production process, and cannot ensure the stability of yarn quality. Summary of the invention

[0008] In view of this, in order to solve the problems raised in the above background technology, an efficient short-process yarn quality prediction analysis and optimization method is proposed.

[0009] The objective of the present invention can be achieved through the following technical solutions: The present invention provides an efficient short-process yarn quality prediction analysis and optimization method, including: S1, basic information acquisition: a number of textile equipment for textile yarns are recorded as designated equipment, and a number of types of yarns that can be spun by each designated equipment are recorded as designated types of yarns, thereby obtaining the basic information of the fiber raw materials of each designated type of yarn and the basic information and basic process parameter information of each designated equipment.

[0012] S4. Yarn quality optimization: Optimize the quality of each specified type of yarn based on the predicted results of the quality grade of each specified type of yarn in weaving each specified equipment.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

[0014] 2.

[0024] It should be further explained that the fiber maturity refers to the degree of thickening of the fiber cell wall, that is, the thickness of the fiber cell wall is taken as the fiber maturity.

[0025] It needs to be further explained that the specific method of obtaining the fiber types of each specified type of yarn is: using a high-definition camera to shoot the fiber raw materials of each specified type of yarn to obtain the fiber raw material pictures of each specified type of yarn, and matching them with the fiber raw material pictures corresponding to each fiber type stored in the information storage library to obtain the fiber types of each specified type of yarn.

[0033] The present invention provides supporting data for subsequent prediction and analysis and optimization of yarn quality by acquiring basic information of fiber raw materials of each specified type of yarn and basic information and basic process parameter information of each specified equipment.

[0034] S2. Basic information analysis: Based on the basic information of each designated equipment, analyze the influencing factors of the quality of each designated type of yarn corresponding to each designated equipment; based on the basic information of each designated type of yarn, analyze the quality of the fiber raw materials of each designated type of yarn; based on the basic process parameter information of each designated equipment, analyze the process quality of each designated equipment when weaving each designated type of yarn.

[0035] As a preferred feasible embodiment, each designated device corresponds to the influencing factor of each designated type of yarn quality, and the specific analysis method includes: extracting the cleanliness, accuracy and stability of each designated device, respectively recorded as ,in , The number of each designated equipment is analyzed to analyze the influencing factors of the quality of each designated equipment corresponding to each designated type of yarn ,in They are extracted from the information repository. The specified type of yarn is The standard cleanliness, standard accuracy and standard stability required for a specified device, They are the permissible difference between the set cleanliness and the standard cleanliness, the permissible difference between the accuracy and the standard accuracy, and the permissible difference between the stability and the standard stability. , The number of each specified type of yarn.

[0036] As a preferred feasible embodiment, in the process of analyzing the quality of the fiber raw materials of each specified type of yarn, it is necessary to construct quality evaluation indexes of fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber rate and fiber impurity content of the fiber raw materials of each specified type of yarn. The specific analysis method includes: extracting the fiber types of each specified type of yarn, and matching them with the reference fiber length, reference fiber fineness, reference fiber strength, reference fiber maturity, reference fiber short fiber rate and reference fiber impurity content of each fiber type stored in the information storage library, so as to obtain the reference fiber length, reference fiber fineness, reference fiber strength, reference fiber maturity, reference fiber short fiber rate and reference fiber impurity content of each specified type of yarn.

[0037] Extract fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber percentage and fiber trash content of each specified type of yarn.

[0038] The fiber length of each specified type of yarn is ratioed with its corresponding reference fiber length, and the obtained ratio is recorded as the fiber length quality evaluation index of the fiber raw material of each specified type of yarn. Similarly, the fiber strength and fiber maturity quality evaluation index of the fiber raw material of each specified type of yarn can be obtained.

[0039] The fiber fineness of each specified type of yarn is ratioed to its corresponding reference fiber fineness, and the obtained ratio is added by one and the reciprocal is taken, and the value is recorded as the fiber fineness quality evaluation index of the fiber raw material of each specified type of yarn. Similarly, the fiber short fiber rate and fiber impurity content quality evaluation index of the fiber raw material of each specified type of yarn can be obtained.

[0040] The present invention analyzes the quality of fiber raw materials of each specified type of yarn to more comprehensively understand the performance characteristics of different yarns, more accurately control the quality during the production process, reduce the defective rate, and improve product quality.

[0041] As a preferred feasible embodiment, in the process of analyzing the yarn textile process quality of each designated device, it is necessary to construct a process quality evaluation coefficient of each designated type of yarn when weaving each designated type of yarn. The specific analysis method includes: extracting the draft multiple, spinning speed, tension and twist of each designated device when weaving each designated type of yarn, respectively recorded as .

[0042] Analyze the process quality evaluation coefficient of each specified equipment when spinning each specified type of yarn ,in They are extracted from the information repository. The standard draft multiple, standard spinning speed, standard tension and standard twist of a specified type of yarn during spinning. They are the allowable difference between the set draft multiple and the standard draft multiple, the allowable difference between the spinning speed and the standard spinning speed, the allowable difference between the tension and the standard tension, and the allowable difference between the twist and the standard twist.

[0043] The process quality evaluation coefficient of each designated equipment when weaving each designated type of yarn is compared with the preset process quality evaluation coefficient threshold. If the process quality evaluation coefficient of a designated equipment when weaving a designated type of yarn is less than the process quality evaluation coefficient threshold, the process quality of the designated equipment when weaving the designated type of yarn is recorded as unqualified; otherwise, the process quality of the designated equipment when weaving the designated type of yarn is recorded as qualified, thereby obtaining the process quality of each designated equipment when weaving each designated type of yarn.

[0044] The present invention fully considers the impact of textile equipment in the yarn production process by analyzing the influencing factors of each designated device corresponding to each designated type of yarn quality and analyzing the process quality of each designated device when weaving each designated type of yarn, thereby more accurately discovering the root causes of yarn quality problems, ensuring timely adjustment and control of these factors in its production process, and helping to ensure the stability of yarn quality.

[0045] S3. Yarn quality prediction: predict the quality grade of each designated type of yarn in the weaving of each designated equipment.

[0046] As a preferred feasible embodiment, when predicting the quality grade of each designated device in weaving each designated type of yarn, it is necessary to construct a comprehensive prediction coefficient of the quality of each designated device in weaving each designated type of yarn, and the specific analysis method includes: extracting the fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber rate and fiber impurity rate quality evaluation index of the fiber raw material of each designated type of yarn, and analyzing and obtaining the strength, elasticity and uniformity of each designated type of yarn, which are respectively recorded as .

[0047] Extract the process quality evaluation coefficient of each specified equipment when weaving each specified type of yarn.

[0048] According to the analytical formula Get the comprehensive prediction coefficient of the quality of each designated equipment in weaving each designated type of yarn ,in They are the weight factors of the comprehensive quality prediction coefficient corresponding to the set yarn quality and the process quality of the equipment when spinning the yarn.

[0049] It should be further explained that the weight factors of the comprehensive quality prediction coefficient corresponding to the set yarn quality and the process quality of the equipment when spinning the yarn can be set to 0.7 and 0.3 respectively.

[0050] As the basic raw material of textiles, the quality of yarn directly affects the performance, appearance and comfort of the final product. When predicting the overall quality of textiles, yarn quality occupies a more core position. Therefore, the weight factor of the comprehensive quality prediction coefficient corresponding to yarn quality is assigned to 0.7, which reflects the dominant position of yarn quality in textile quality control.

[0051] Yarn quality is the foundation, but the process quality of the equipment also has an important impact on the quality of textiles. Factors such as the operating status, accuracy and stability of the equipment will directly affect the production efficiency and quality of the yarn. Therefore, the weight factor of the comprehensive quality prediction coefficient corresponding to the process quality of the equipment when spinning yarn is assigned to 0.3, which not only takes into account the importance of the process quality of the equipment, but also reflects its auxiliary position in the entire quality control system.

[0052] As a preferred feasible embodiment, the prediction of the quality grade of each designated device in weaving each designated type of yarn specifically includes: matching the comprehensive quality prediction coefficient of each designated device when weaving each designated type of yarn with the comprehensive quality prediction coefficient range corresponding to each yarn quality grade stored in the information reserve library, so as to obtain the yarn quality grade of each designated device when weaving each designated type of yarn.

[0053] As a preferred feasible embodiment, the strength, elasticity and uniformity of each specified type of yarn are specifically obtained by matching each specified type of yarn with an exclusive analysis model corresponding to each specified type of yarn belonging to a preset analysis model to obtain an exclusive analysis model corresponding to each specified type of yarn.

[0054] By inputting the fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber rate and fiber impurity content quality evaluation index of the fiber raw materials of each specified type of yarn into its corresponding exclusive analysis model, the strength, elasticity and uniformity of each specified type of yarn can be obtained.

[0055] As a preferred feasible embodiment, the specific acquisition method of the preset analysis model includes: F1, training data acquisition: randomly select several groups of fiber raw materials of a specified type of yarn with known fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber rate and fiber impurity rate, weave them to obtain several groups of the specified type of yarn, and then test them to obtain the strength, elasticity and uniformity of several groups of the specified type of yarn, and then use the fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber rate and fiber impurity rate of several groups of fiber raw materials of the specified type of yarn and the strength, elasticity and uniformity of several groups of the specified type of yarn as training data.

[0056] F2. Establishment of training model: The training model consisting of an input layer, a hidden layer and an output layer is recorded as a target training model, wherein the fiber length, fiber fineness, fiber strength, fiber maturity, fiber short fiber rate and fiber impurity rate of several groups of fiber raw materials of the specified type of yarn are used as input vectors of the input layer in the target training model, and the strength, elasticity and uniformity of several groups of the specified type of yarn are used as output vectors of the output layer in the target training model.

[0057] F3. Data training: Train the target training model to obtain the hidden parameter matrix in the target training model, and use it as the parameter matrix of the hidden layer in the exclusive analysis model corresponding to the specified type of yarn.

[0058] F4. Obtaining the analysis model: The trained target training model is used as the exclusive analysis model corresponding to the specified type of yarn. Similarly, the exclusive analysis model corresponding to each specified type of yarn can be obtained. The exclusive analysis models corresponding to each specified type of yarn are collectively referred to as analysis models.

[0059] It should be further explained that each designated type of yarn corresponds to an exclusive analysis model such as Figure 2 As shown, the exclusive analysis model corresponding to each specified type of yarn includes an input layer, a hidden layer and an output layer.

[0060] It needs to be further explained that the exclusive analysis model corresponding to each designated type of yarn is obtained by building a neural network. In a neural network, the input layer, hidden layer and output layer are the basic components of the network structure.

[0061] The input layer is the beginning of the neural network, which receives input data from the outside world. Each neuron in the input layer represents an input feature. The input layer does not perform any calculations, it just passes the input data to the next layer, the hidden layer.

[0062] Specifically, the fiber length, fiber fineness, fiber strength, fiber maturity, fiber fuzz rate and fiber impurity rate of the fiber raw material of the specified type of yarn are the neurons of the input layer.

[0063] The hidden layer is located between the input layer and the output layer and is the part of the neural network that actually performs calculations. There can be one or more hidden layers, and each hidden layer can have multiple neurons. These neurons are connected to the neurons in the previous layer through weighted connections, i.e. weights, and receive the output from the previous layer as input. Each neuron performs a weighted summation of its inputs and applies an activation function to produce an output. This output will serve as the input for the next layer of neurons. The main role of the hidden layer is to learn the feature representation of the input data and capture the complex relationship between input and output.

[0064] The output layer is the last layer of the neural network, which receives the output from the last hidden layer and produces the final output of the network. The number of neurons in the output layer depends on the specific task. Similar to the neurons in the hidden layer, the neurons in the output layer also perform a weighted sum of their inputs and apply an activation function to produce the output. The output of the output layer can be used to compare with the true label to calculate the loss function and backpropagate to update the weights during training.

[0065] Specifically, the strength, elasticity and uniformity of the specified type of yarn are the neurons of the output layer.

[0066] S4. Yarn quality optimization: Optimize the quality of each specified type of yarn based on the predicted results of the quality grade of each specified type of yarn in weaving each specified equipment.

[0067] As a preferred feasible embodiment, the optimization of the quality of each specified type of yarn includes: extracting the yarn quality grade of each specified device when weaving each specified type of yarn, and extracting the process quality of each specified device when weaving each specified type of yarn.

[0068] It should be further explained that the yarn quality grades include A-grade yarn, B-grade yarn, C-grade yarn and D-grade yarn.

[0069] Among them, grade A yarn is the highest quality yarn with good quality, high strength and beautiful appearance.

[0070] Grade B yarn is a yarn of medium quality. Compared with grade A yarn, it has some shortcomings, but has stable quality and higher strength.

[0071] C grade yarn is of average quality and has obvious defects, but if it is improved under corresponding technical conditions, satisfactory products can be obtained.

[0072] D-grade yarn is of poor quality and has many defects and shortcomings.

[0073] It is analyzed according to preset principles to obtain optimization suggestions for the quality of each specified type of yarn and provide feedback.

[0074] It needs to be further explained that the specific contents of the preset principles include: extracting the process quality conditions of each designated equipment when weaving each designated type of yarn, and extracting each designated equipment whose process quality conditions when weaving each designated type of yarn are unqualified, and recording them as unqualified equipment. Similarly, qualified equipment can be obtained.

[0075] From the yarn quality grades of each designated device when weaving each designated type of yarn, the yarn quality grades of each unqualified device when weaving each designated type of yarn and the yarn quality grades of each qualified device when weaving each designated type of yarn are extracted.

[0076] If the yarn quality grade of each qualified equipment when weaving each specified type of yarn is grade A yarn or grade B yarn, and the yarn quality grade of each qualified equipment when weaving each specified type of yarn is higher than the yarn quality grade of each unqualified equipment when weaving each specified type of yarn, then the optimization suggestions for the quality of each specified type of yarn are recorded as optimized equipment.

[0077] If the yarn quality grades of each qualified device and each unqualified device when weaving each specified type of yarn are both C-grade yarn or D-grade yarn, the optimization suggestions for the quality of each specified type of yarn are recorded as optimized fiber raw materials.

[0078] The present invention helps to reduce the defective product rate, reduce the waste of raw materials and energy, and also helps to reduce quality fluctuations and production interruptions caused by equipment failures, thereby reducing production costs by predicting and optimizing the quality grade of each specified type of yarn.

[0079] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.
