Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
First, the terms referred to in the embodiments of the present application will be briefly described:
knitted fabrics, which are fabrics formed by hooking yarns into loops with a knitting needle and interlooping the loops, are classified into two categories, namely weft knitting and warp knitting, and are widely used in various aspects of production and life. The weaving process of knitted fabrics on a knitting machine can be divided into three stages: feeding yarn, looping and winding. When the color of the knitted fabric is realized in multiple colors, the multi-color fabric needs to be woven by the color yarns in multiple colors.
Circular weft knitting machines, also known as circular weft knitting machines, are knitting machines in which the needles are arranged on a circular needle cylinder for producing a cylindrical weft-knitted fabric. In the related art, a circular knitting machine is often used to knit a multicolor fabric. When the circular knitting machine weaves multicolor fabrics, the circular knitting machine comprises thread adjusting fingers, and the thread adjusting fingers can switch color yarns with different colors so as to realize the effect that the fabrics have multiple colors. In the related art, 4 yarn adjusting fingers or 6 yarn adjusting fingers can be included in the circular knitting machine. The specific number of the thread adjusting fingers is related to the model of the circular knitting machine, and the application is not limited herein.
Fig. 1 is a flowchart illustrating a method for testing weavability of a multi-tone wale knitted fabric according to an exemplary embodiment of the present application, which is described by way of example as being applied to a computer device, and includes:
In the embodiment of the application, the pattern artistic conception drawing is an original pattern for guiding the weaving of the multi-tone line horizontal stripe knitted fabric.
In this embodiment of the present application, optionally, the knitting machine is implemented as a yarn adjusting circular knitting machine, and the knitting machine data is also data corresponding to the circular knitting machine. In one example, the knitting machine data includes at least one of a type of knitting machine, a number of stitch systems of the knitting machine, and a number of stitch fingers of the knitting machine. Optionally, the knitting machine data should include at least the number of stitch fingers of the knitting machine. In one example, the weaving machine is communicatively connected to a computer device that can directly retrieve weaving machine data associated with the circular knitting machine.
And 102, generating color information and process information based on the pattern design drawing.
In the embodiment of the application, after the computer equipment obtains the pattern design drawing, color information and process information can be generated according to the pattern design drawing information. The color information and the process information are both embodied in the form of data segments. The color information is used for indicating the knitting color of the knitted fabric with the multi-tone line and the process information is used for indicating the type of the loops applied in the process of knitting the knitted fabric with the multi-tone line and the horizontal bar.
And 103, generating a yarn guide model based on the knitting machine data, the color information and the process information.
In the embodiment of the present application, after the computer device determines the data of the knitting machine for knitting the multi-tone line bar knitted fabric and the information related to the multi-tone line bar knitted fabric itself, the computer device generates a yarn guide model that can indicate the color yarn codes introduced in each knitting line of the knitting system during the course of knitting a number of pattern cycles. In the embodiment of the present application, the contents that the color yarn code can indicate include the color, the raw material and the fineness of the color yarn. That is, the yarn guide model is a set of color yarn codes introduced into each knitting line of the knitting system in the knitting process.
And 104, generating a threading model based on the yarn guide model and the knitting machine data.
In the embodiment of the application, the computer device can generate the threading model according to the template pre-stored in the computer device by combining the knitting machine data of the circular knitting machine and the specific content in the yarn guide model. The threading model can indicate the actual threading condition of thread adjusting fingers for the knitting process of the multi-tone line horizontal stripe knitted fabric. Therefore, the threading model includes the number of theoretical finger adjustments.
And 105, comparing the number of the theoretical yarn adjusting fingers with the number of the yarn adjusting fingers of the knitting machine, and determining the result of verifying the weavability of the multi-color yarn horizontal stripe knitted fabric.
In the embodiment of the application, the number of the theoretical thread adjusting fingers is the number of the thread adjusting fingers which are necessary when the circular knitting machine is used for knitting the multi-tone-thread horizontal bar knitted fabric. Based on the number of the stitches-adjusting fingers, the result of verifying the knittability of the multi-color-adjustment wale knitted fabric can be determined. In one example, when the theoretical number of the thread-adjusting fingers is less than or equal to the number of the thread-adjusting fingers of the knitting machine, it is determined that the multi-tone wale knitted fabric can be knitted by the knitting machine; in another example, when the theoretical stitch adjusting number of fingers is larger than the stitch adjusting number of fingers of the knitting machine, it is determined that the multi-tone wale knitted fabric cannot be knitted by the knitting machine. The present application is not limited to a specific knitting condition of the multi-tone wale knitted fabric, and in the related art, it is generally determined that the multi-tone wale knitted fabric can be knitted by the knitting machine when the number of the theoretical tuning fingers is less than or equal to the number of the tuning fingers of the knitting machine.
In summary, in the method provided by the embodiment of the present application, in the yarn arrangement process, with the aid of a computer device, the design drawing and the related data of the knitting machine are used as the original input of the test method, and in the case of combining the fabric drawing of the multi-tone line and the related data of the knitting machine, the color information and the process information of the multi-tone line and bar knitted fabric are extracted, and further a yarn guide model and a yarn threading model are established, so that the reasonability of the multi-color fabric corresponding to the design drawing is determined by taking the number of used yarn-adjusting fingers as a standard. In the process of testing the weavability of the multicolor fabric, the form of the artistic conception drawing and the information of the weaving machine are comprehensively considered, the textile requirement of the fabric with the artistic conception drawing is determined through the extraction of relevant parameters and the generation of the model, the difficulty degree of yarn arrangement can be reduced, and the labor cost in the yarn arrangement process can be reduced.
Fig. 2 is a flowchart illustrating another method for testing weavability of a multi-tone wale knitted fabric according to an exemplary embodiment of the present application, which is described by way of example as being applied to a computer device, and includes:
The process is the same as the process shown in step 101, and is not described herein.
In the embodiment of the application, the computer device can receive the pattern design drawing in the form of a picture, and convert, extract and output the information in the pattern design drawing in the form of a two-dimensional pattern data matrix. Optionally, in the two-dimensional pattern data matrix, the content of each element corresponds to the content of each artistic conception lattice in the pattern artistic conception drawing.
And step 203, generating a color data matrix based on the two-dimensional pattern data matrix.
In the embodiment of the application, the color data matrix is used for directly indicating the colors of the design grids in the flower-type design grid, the color data matrix comprises at least one color data, the number of the color data corresponds to the number of the design grids in the flower-type design grid, and the positions of the color data correspond to the color positions of the flower-type design grid.
In one example, the color data matrix P is of the form shown in equation 1 below:
formula 1:
wherein w represents the height of the flower pattern in the artist's cell, h represents the height of the flower pattern in the artist's cell, and P(j,k)The color code of the flower pattern of the jth transverse row and the kth longitudinal row is shown.
And 204, generating a process weaving data set based on the two-dimensional pattern data matrix.
In the embodiment of the present application, the process weaving data set is also embodied in the form of a matrix. Alternatively, the set of technical knitting data represents the stitch type of the dyed yarn at each needle position of each row of knitting.
In one example, the representation of the process weave data set K is shown in equation 2 below:
formula 2:
wherein w and H are the width and height of the knitting cycle, respectively, K(j,k)The stitch number of the kth wale for the jth weaving row.
And step 205, determining the dyed yarns corresponding to the knitted multi-tone line horizontal stripe fabric and the used quantity of the dyed yarns corresponding to the dyed yarns based on the color data matrix.
In the embodiment of the application, the specific type of the selected colored yarn and the dosage of each colored yarn can be obtained when the color data matrix is combined to weave the multi-tone line and horizontal stripe knitted fabric. Alternatively, the amount of colored yarn may be displayed from the size ratio of the different colors in the artisan's drawings.
And step 206, generating a dyed yarn code sequence based on the used quantity of the dyed yarns.
In the embodiment of the application, the colored yarn code sequence takes the amount of the colored yarn as a standard and sorts the colored yarn. In one example, the colored yarn sequences are embodied and sorted by English letters, and each letter data in the sequences contains yarn information such as color, raw materials, fineness and the like.
In the embodiment of the application, the colored yarn weaving sequence takes the amount of the colored yarn as a standard and carries out sequencing on the colored yarn.
And step 207, generating a colored yarn weaving sequence based on the colored yarn code sequence.
In the present embodiment, the colored yarn knitting sequence indicates a colored yarn code number within a knitting line.
The process is a process of determining the color yarn number sequence, and then determining the color yarn used in each knitting line and generating a corresponding sequence, and in one example, the form of the color yarn knitting sequence Y is shown in the following formula 3:
formula 3: y ═ Y1 … Yi … YH]
In the formula, YiThe dyed yarn used in the ith weaving row is coded.
And step 208, combining the knitting machine data and the process knitting data set based on the colored yarn knitting sequence to generate a yarn guide model.
The process is the generation process of the yarn guide model. Optionally, the computer device performs the assignment of yarn guide instructions to yarn adjusting devices within a knitting system in the knitting machine based on the received knitting machine data. In the case where the knitting cycle height is determined to be H and the number of machine knitting systems is determined to be S, the least common multiple of the two is calculated and recorded as l. Then n patterns can be woven after the machine runs r turns. Wherein r is l/S, and n is l/H. In this case, the yarn guide model G is established as shown in the following formula 4:
formula 4:
in the formula, G(j,k)Indicating the color yarn code introduced by the k-th loop-forming system at j-th turn of the knitting machine.
According to looping system number S, data traversal is carried out to the yarn guide model to revolution r to the corresponding colored yarn code assignment in weaving the sequence model with the colored yarn is to the yarn guide model in proper order, can obtain formula 5:
formula 5: g(j,k)＝Y(j×S+k)modH
In the formula, "mod" represents a remainder obtained by dividing an integer (j × S + k) by an integer (H).
And step 209, determining a yarn arrangement principle based on the colored yarn weaving sequence.
The process is a front step of generating a threading model. In the process, the computer equipment determines the yarn arrangement priority in the yarn threading process according to the color yarn weaving sequence. In one example, the colored yarn indicating the higher value in the colored yarn weaving sequence is determined as the colored yarn to be preferentially selected in the yarn arranging principle. In another example, the colored yarn indicating the lower color yarn in the colored yarn weaving sequence will be selected as the colored yarn preferred in the yarn arranging principle. The practical content of the yarn arrangement principle is not limited in the embodiment of the application.
And step 210, determining the number range of the theoretical line-adjusting fingers based on the data of the knitting machine.
Like the process shown in step 209, this process is also a pre-step in the generation of the threading model. In some embodiments, the number of the theoretical yarn adjusting fingers of the computer device in the simulated yarn arranging process is determined according to the actual number of the yarn adjusting fingers of the knitting machine, so as to prevent the number of the theoretical yarn adjusting fingers from being too different from the number of the yarn adjusting fingers actually possessed by the knitting machine data.
And step 211, generating a threading model based on the yarn guide model and the knitting machine data according to the yarn arrangement principle.
In the embodiment of the present application, the actual implementation form of the threading model T is shown in the following formula 6:
formula 6:
all the time, f represents the index of the yarn adjusting hand in each loop forming system of the knitting machine, and T (j, k) represents the code number of the color yarn penetrated by the jth yarn adjusting finger in the kth loop forming system.
And (4) according to the yarn guide model G, arranging the colored yarn codes appearing in each looping system in the yarn threading model T according to a certain principle. In one example, the number of the theoretical thread-adjusting fingers is more than four, the yarn arrangement principle is that the color yarn A, B, C, D with higher use frequency is preferentially arranged in the first 4 fingers, and the rest color yarns with lower use frequency penetrate into vacant positions in the thread-adjusting fingers 1, 2, 3 and 4 according to the weaving rule.
And 212, comparing the number of the theoretical yarn adjusting fingers with the number of the yarn adjusting fingers of the knitting machine, and determining the result of verifying the weavability of the multi-color yarn horizontal stripe knitted fabric.
Optionally, in the embodiment of the application, in response to the number of the theoretical yarn adjusting fingers being larger than the number of the yarn adjusting fingers of the knitting machine, determining that the result of verifying the weavability of the multi-color yarn horizontal stripe knitted fabric is unwoven;
and determining the result of the verification of the weavability of the multi-tone-line horizontal stripe knitted fabric as weavability in response to the fact that the number of the theoretical line adjusting fingers is less than or equal to the number of the line adjusting fingers of the knitting machine.
It should be noted that when the number of the theoretical thread adjusting fingers is larger than that of the knitting machine, the specific position of the non-knitting reason can be determined through the threading model. In this case, the computer device may determine the positions of the pattern rows and the weave rows and generate optimization suggestions accordingly.
In summary, in the method provided by the embodiment of the present application, in the yarn arrangement process, with the aid of a computer device, the design drawing and the related data of the knitting machine are used as the original input of the test method, and in the case of combining the fabric drawing of the multi-tone line and the related data of the knitting machine, the color information and the process information of the multi-tone line and bar knitted fabric are extracted, and further a yarn guide model and a yarn threading model are established, so that the reasonability of the multi-color fabric corresponding to the design drawing is determined by taking the number of used yarn-adjusting fingers as a standard. In the process of testing the weavability of the multicolor fabric, the form of the artistic conception drawing and the information of the weaving machine are comprehensively considered, the textile requirement of the fabric with the artistic conception drawing is determined through the extraction of relevant parameters and the generation of the model, the difficulty degree of yarn arrangement can be reduced, and the labor cost in the yarn arrangement process can be reduced.

and step 301, designing a pattern.
The process is the generation of the design drawing and the computer acquisition process of the design drawing.
In one example, the pattern design drawing size is 384 courses by 25 wales, with color codes drawn from bottom to top as: [ column (color No. 1) & lt 4 > + (color No. 2) 2 column ]. times 16 cycles + [ (2 color) 2 column + (3 color) 2 column ]. times 2 cycles + [ (2 color) 2 column + (4 color) 2 column ]. times 2 cycles + [ (2 color) 2 column + (5 color) 2 column ]. times 2 cycles + [ (2 color) 2 column + (6 color) 2 column ]. times 2 cycles + [ (2 color) 4 column + (7 color) 2 column ]. times 16 cycles + [ (7 color) 2 column + (8 color) 2 column ]. times 2 cycles + (7 color) 2 column + (9 color) 2 column ]. times 2 cycles + [ (7 color) 2 column + (10 color) 2 column + (2 cycle + (2 column + (2 + (10 color) 2 column + (2 cycle + (7 color) 2 column + (2 color) 2 column + (2 cycle + (2 column (11 color) 2 + (2 column). times 2 + (2 column (2 + (11 color) 2 + (2 column). times 2 + (2 cycle + (1 + (2 column). times 2 + (2 column (2 + (11 color) 2 + (1 + (2 cycle + (1 +) Color No. 1, 2 courses + (color No. 10) 2 courses ] × 2 cycles + [ (color No. 1) 2 courses + (color No. 9) 2 courses ] × 2 cycles + [ (color No. 1) 2 courses + (color No. 8) 2 courses ] × 2 cycles.
And step 302, generating a pattern model P and a weaving model K.
The process is a process of generating a color data matrix and a process weaving data set.
In the example shown in step 301, h is 384 and w is 25 in the color data matrix and the weave model.
And step 303, reordering the color codes to generate a color yarn weaving sequence model Y.
In the example shown in step 301, please refer to fig. 4, the color code number on the pattern recognition map is 401-: and (4) dyeing yarn code sequence. The color yarn sequence is named by English letters A-K, the corresponding rule is 401-A, 402-B, 407-C, 408-D, 409-E, 410-F, 411-G, 403-H, 404-I, 405-J and 406-K, each datum in the sequence comprises yarn information such as color, raw materials, fineness and the like, and after a color yarn code sequence is generated, the color yarn used in each weaving line is determined to generate a color yarn weaving sequence model Y.
And step 304, generating a yarn guide model G according to the machine parameters.
In the example shown in step 301, it is assumed that the pattern is woven using a 4-tone yarn circular knitting machine, the number of loop formation systems of which is 48, and each yarn adjusting device has 4 yarn adjusting fingers. As known, the pattern row height of the pattern design drawing is 384 rows, and because each row only has one color, the weaving row height is 384 rows after the development and decomposition. Then the least common multiple l of the number S of the looping systems and the weaving rows H is calculated to be 384, namely 1 complete pattern organization cycle is completed after 8 turns of the circular knitting machine. The size of the yarn guide model G is 8 rows × 48 columns, the yarn guide model G is traversed, the color yarn code numbers in the color yarn knitting sequence Y are sequentially assigned to the yarn guide model G, and the obtained yarn guide model G is as shown in a yarn guide model 500 in fig. 5, and the color yarns are represented by the corresponding code numbers in the yarn guide model 500.
And 305, generating a threading model T according to a threading principle.
In the example shown in step 301, the dyed yarns A, B, C, D are preferentially arranged according to the dyed yarn application ratio and correspond to the fingers No. 1, 2, 3 and 4 respectively, and the rest dyed yarns are subjected to position compensation in each yarn adjusting finger according to the knitting rule. Fig. 6 is a schematic diagram of the generation of the threading model T. In fig. 6, the numbers increase from top to bottom in the longitudinal direction, i.e., the numbers 1 to 6 indicate the stitch hand index f, and the numbers increase from left to right in the transverse direction, i.e., the numbers 1 to 48 indicate the number of the machine looping systems. Illustratively, T (2,19) ═ J denotes that the 2 nd stitch finger of the stitch rounding machine penetrates the dyed yarn J at the 19 th stitch system.
In response to the threading scheme being available, step 307 is executed. In the example shown in step 301, the pattern can be woven normally on a 4-tone circular loom.
And 307, weaving on a machine.
The process is a direct weaving process.
In response to the threading scheme not being feasible, steps 308 to 309 are performed.
And step 308, proposing an optimization suggestion.
The process shown in steps 308 to 309 is an optimization proposal and adjustment process for the threading scheme by the computer device.
