Fig. 2 shows a flow chart of another method for testing weavability of a weft-knitted double-sided loop transfer knitted fabric according to an exemplary embodiment of the present application, which is described by taking the method as an example applied to a computer terminal, and the method 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 terminal can receive the transfer pattern graph in the form of a picture, and convert, extract and output the information in the transfer pattern graph in the computer terminal in the form of a two-dimensional information set. Optionally, the content of each element in the two-dimensional information set corresponds to the content of each cell in the transfer pattern diagram one to one.
And step 203, integrating the transfer pattern array based on the two-dimensional information set.
In this embodiment of the application, the transfer flower color array is used for directly indicating the color of the artistic conception grid in the transfer flower type diagram, the transfer flower color array comprises at least one flower color number, the actual flower color number corresponds to the artistic conception grid number of the transfer flower type diagram, and the positions of the flower color number correspond to the color positions of the transfer flower type diagram.
In one example, the array of transfer suit is stored in the computer terminal in the form of a matrix C, as shown in equation 1 below:
formula 1:
wherein w and h are the width and height of the transfer pattern unit cell respectively, and c (i, j) represents the weave code of the ith wale of the jth transverse row of the fabric.
And step 204, integrating a transfer motion array based on the two-dimensional information set.
In the embodiment of the present application, the transfer motion array is also embodied in the form of a matrix. Alternatively, the transfer motion array represents the knitting motion of the yarn at each needle position of each process row.
In one example, the transfer motion array T is represented by equation 2 below:
formula 2:
in the formula, w and H are the width and height of the corresponding unit cell of the element in the two-dimensional information set respectively, and t (i, j) represents the action code of the ith row and the ith column of the jth row of the fabric.
In the embodiment of the application, the weaving pattern chart is used for guiding the process weaving of the weft-knitted double-sided loop transfer knitted fabric. Optionally, the content of each cell in the woven pattern diagram corresponds to the content of the woven action information element in the loop transfer action array one to one.
And step 206, traversing the knitting process rows for knitting the weft-knitted double-sided loop transfer knitted fabric based on the loop transfer action array and the actions of the knitting needles in the process rows.
In the embodiment of the application, the specific knitting conditions of the process rows and the knitting action of each knitting needle in each process row when the weft-knitted double-sided loop transfer knitted fabric is knitted can be obtained by combining the loop transfer action arrays. Alternatively, the knitting motion of the technical row of knitting needles can be obtained from the display of different cell colors in the knitting pattern diagram.
And step 207, integrating action knitting needle row number indexes based on the knitting action of the technical line knitting needles.
In the embodiment of the application, the row number index of the action knitting needle traverses the knitting action of the technical line knitting needle to row the number of the technical line knitting needle. In one example, the active needle indices are sorted by number, each number field in the index containing information on yarn stock, knitting system, needle activity, etc.
In the embodiment of the application, the row number index of the action knitting needle traverses the knitting action of the technical line knitting needle to row the number of the technical line knitting needle.
And step 208, integrating knitting needle indexes based on the action knitting needle row number indexes.
In the embodiment of the application, the knitting needle index indicates the knitting action index of the knitting needle of the technical row in the previous knitting row.
The process is a process of determining knitting actions of the needles in the previous knitting row of the technical row of the needles after determining the row number index of the action needles and integrating corresponding indexes, and in one example, the knitting needle index a is in the form shown in the following formula 3:
formula 3: a ═ a (1, j) … a (i, j) … a (w, j) ]
In the formula, a (i, j) is a knitting needle with the row number i of the technical row in the j knitting row. In one example, knitting needle indices are ordered in alphabetical representation, and each alphabetical segment in the index contains information on yarn material, knitting system, needle motion, and the like.
And step 209, integrating a process design model by combining the transfer design color array, the transfer motion array and the parameters of the knitting machine based on the row number index of the motion knitting needle.
This process is an integration process for performing a process design model. Optionally, the computer terminal performs the distribution of knitting instructions to knitting devices within a knitting system in the knitting machine based on the received knitting machine parameters. Under the condition that the weaving cycle height is determined to be H, the process design model K is established as shown in the following formula 4:
formula 4:
in the formula, k (i, j) represents the knitting action of the knitting machine on the knitting needle of the ith process row of the jth row of the fabric.
And traversing data of the process design model, and correspondingly assigning the information in the action knitting needle row number index to the process design model in sequence.
And step 210, determining a system threading principle based on the knitting needle index.
The process is a pre-step of integrating the braided structural model. In this process, the computer terminal determines the allocation of the knitting system and of the transfer system during the knitting process according to the index of the knitting needles of the knitting.

and responding to the fact that the type of the theoretical knitting needle knitted loop is tuck, determining that the weft-knitted double-sided transfer knitted fabric is unstable when being knitted by a knitting machine, and giving an alarm before the knitting machine performs knitting.
It should be noted that when the type of the loop knitted by the theoretical knitting needle is not single loop, the specific position of the reason causing the pre-knitting alarm can be determined by the knitting structure model. In this case, the computer terminal may determine the locations of the rows of technology and the rows of weave and integrate the optimization suggestions accordingly.
