Description

Weaving method of mat-like knitted fabric

Technical Field

The invention relates to the field of knitting methods of knitted fabrics by a flat knitting machine, in particular to a knitting method of a mat-imitating knitted fabric.

Background

In the past, the twisting weaving is one of popular pattern weaves in the flat knitting machine, two groups of wales (a single wale contains 1-3 loops) are usually crossed and overlapped on different weaving transverse columns to enable the fabric to generate patterns with twisted rope-shaped appearance, and three groups or four groups of wales are also arranged on different weaving transverse columns, and every two wales are crossed and overlapped to enable the fabric to generate patterns with braid-shaped appearance.

The crossing and overlapping of the wales with each other is conditional in practice, the knitting process is easy and the fabric appearance is flat if the number of stitches in the wales is 1 or 2, and the knitting may be broken if the number of stitches in the wales is 3 or more, and the knitted fabric may be uneven.

Disclosure of Invention

The invention aims to provide a knitting method of a mat-imitating knitted fabric, which enables the knitted fabric to present the appearance of the existing knitting and solves the problems of broken lines and unevenness generated in the existing knitting.

In order to solve the technical problems, the technical scheme of the invention is as follows: in a flat knitting machine using a pair of front and rear needle beds or a multi-needle bed, a stitch can freely move forward and backward on the front and rear needle beds; the invention relates to a knitting method of a mat-imitating knitted fabric, which divides a stitch course with a pattern width into a right crossing group and a left crossing group, a knitting needle always carries out normal longitudinal knitting on normal and enlarged stitch courses, the stitch of the right crossing group always moves rightwards and the stitch of the left crossing group always moves leftwards on each crossing and overlapping course, when finishing the knitting of one crossing and overlapping course, the knitting process is as follows:

step a: carrying out normal loop knitting of n (n is 1, 2 or 3) knitting courses on knitting needles on one needle bed;

step (b): knitting a loop of a knitting needle on one needle bed, knitting a hanging loop of a knitting needle on the other needle bed, and then putting the loop of the knitting needle on the other needle bed;

step y: transferring the coils on one needle bed to the corresponding knitting needles on the other needle bed;

step δ: after the loop groups are mutually crossed and overlapped, the loop group positioned on the front surface of the fabric is transferred to a knitting needle corresponding to one needle bed;

step ζ: after the stitch groups are crossed and overlapped, the stitch group on the back of the fabric is transferred to a knitting needle corresponding to one needle bed.

The invention has the following beneficial effects: (1) the knitting method of the present invention is different from the twist knitting with two sets of wales to give a fabric having a rope-like appearance and is different from the twist knitting with three or four sets of wales to give a fabric having a braid-like appearance, by always performing the usual longitudinal knitting with the knitting needle on the regular and enlarged courses, on each crossing and overlapping row, the coils of the right crossing group always move rightwards, and the coils of the left crossing group always move leftwards, thereby forming a plurality of groups of wales inclined upwards from left to right and wales inclined upwards from right to left, the weaving of the twist is finished on each crossed and overlapped row, so that the fabric has the patterns of the inclined mat-imitating weaving, for example, the fabric has the patterns of the mat-imitating weaving in an inclined shape of one over one under the other or two over two under the other through the difference of the transfer sequence.

(2) In a typical twist knitting, when the number of stitches in a stitch row is 3 or more, a broken thread may occur. And the woven fabric is uneven, the weaving method of the invention converts the yarn on the hanging loop into the coil of the front needle bed through the working procedure beta, which is called the releasing loop treatment, to enlarge the coil, thus being beneficial to reducing the difficulty of subsequent loop transfer weaving and enabling the woven fabric to have flat appearance.

Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and examples. The method comprises the following specific steps:

implementation mode one

Fig. 1 is a diagram of a first embodiment, which includes, as viewed in a longitudinal direction of a fabric, a cycle of 2 regular courses and 1 enlarged course, and the enlarged courses are a plurality of 3 × 3 twisted weaves, and a schematic diagram of the enlarged courses is correspondingly given in order to more clearly reflect a grain effect of a woven mat, as shown in fig. 2, in the diagram, courses with a pattern width of 30 are equally divided into 10 groups, each group includes 3 loops, wherein odd numbers a, c, e, g, i are right crossing groups, and even numbers b, d, f, h, j are left crossing groups; the cross and overlap courses formed by each group are sequentially marked as 1, 2, 3, 4, 5, 6, 7 and 8 courses when viewed from bottom to top along the wale direction, the knitting needle always carries out common longitudinal knitting on the conventional and enlarged stitch courses, the stitches of the right cross group always move rightwards and the stitches of the left cross group always move leftwards on each cross and overlap course, and therefore, a plurality of groups of wales inclined upwards from left to right and wales inclined upwards from right to left are formed, as shown in fig. 3. FIG. 3 is a schematic diagram showing the positions of the coil groups after transferring and overlapping, corresponding to FIG. 2, when the 2 nd cross and overlapping row is completed, the left side portion of the coils in the left cross group b will be shifted out from the defined pattern width, and correspondingly there will be a state in which the coils in the right cross group A are shifted in from the left side, and the right side portion of the coils in the right cross group i will be shifted out, and the coils in the left cross group E will be shifted in, similar to the left side portion; after the other crossing and overlapping courses are completed, the positions, the moving-in and the moving-out of the left and right crossing groups are shown in 3-8 courses in fig. 3.

Fig. 4 is a knitting process diagram of the first embodiment, in which "S + number" in the left column indicates a knitting process number, the right column indicates a specific knitting state, FB indicates a front needle bed (one needle bed), BB indicates a rear needle bed (the other needle bed), "·" indicates knitting, "ro" indicates a stitch, a thin solid line indicates an existing old stitch, a thick solid line indicates a new stitch being knitted, "Λ" indicates a pick-up, "a" indicates a miss, an arrow indicates a transfer, and Y1 and Y2 indicate types of yarns used for knitting in each course.

S0, the knitting needles of the front needle bed have 30 old stitches, and the stitches are divided into right-hand and left-hand crossing groups, and from this state, knitting of the mat-like knitting type is performed.

S1, normal stitch knitting (step α) is performed for n knitting courses with the knitting needle on the front needle bed using the yarn Y1, n =2 in the present embodiment, and two courses knitting here are not fixed, and one or three courses knitting may be selected.

S2, knitting needles on the front needle bed are knitted with stitches using the yarn Y1, and knitting needles on the rear needle bed are knitted with loops (first half of step β).

S3, the knitting needle on the back needle bed is subjected to a widening process (the latter half of step β).

S4, the stitches on the front needle bed are transferred to the knitting needles corresponding to the back needle bed (step γ).

S5, the stitch groups on the front fabric surface after crossing and overlapping each other are transferred to the front needle bed (step δ). In the present embodiment, the left cross groups b, d, f, h, j are shifted to the left from the back needle bed to the front needle bed by three needles.

S6, the stitch groups are crossed and overlapped with each other, and then the stitch group on the back surface of the fabric is transferred to the front needle bed (step ε). In the present embodiment, the right crossing groups a, c, e, g, i are shifted to the right from the rear needle bed to the front needle bed by three needles.

S7, the steps S1 to S4 are repeated, and the steps are the same as the steps S1 to S4 except that the stitch knitting is performed using the yarn Y2 in the steps α and β, and the yarn may not be replaced.

At S8, the stitch groups on the front face of the fabric are transferred to the front needle bed after crossing and overlapping each other (step δ). Note that in S8, reference is made to fig. 3 by the shifted-in coil group a, and the shifted-out coil group i.

At S9, the stitch groups on the back surface of the fabric after crossing and overlapping each other are transferred to the front needle bed (step ∈). in the present embodiment, the left crossing group b, d, f, h, j is transferred to the front needle bed by three stitches to the left from the back needle bed. Note that in S9, reference is made to fig. 3 by the shifted-in coil group E, and the shifted-out coil group b.

In fact, S1-S6 complete the knitting of the 1 st cross, overlapping course in FIG. 2; S7-S9 complete the knitting of the 2 nd crossing and overlapping course in fig. 2, and each crossing and overlapping course needs five knitting steps of step α → step β → step γ → step δ, and the knitting of the other crossing and overlapping courses in fig. 2 is the same as the knitting steps of S1-S9, and only the moving-in and moving-out stitch groups need to be paid attention to.

S2-S3, namely the process beta, is called a releasing treatment, after the hanging loop in S2 is released by S3, the hanging loop yarn is converted into the loop of the front needle bed, so that the loop becomes larger, which is beneficial to reducing the difficulty of subsequent transfer knitting and can also make the knitted fabric externally smooth. As can be seen from the physical fig. 1, the length of the crossed and overlapped coils is significantly large.

In S5-S6, all left-hand cross over groups are transferred in S5 (step δ) to the front of the cross, overlap course 1, all right-hand cross over groups are transferred in S6 (step ∈) to the back of the cross, overlap course 1, in S8-S9 all right-hand cross over groups are transferred in S8 (step δ) to the front of the cross, overlap course 2, and all left-hand cross over groups are transferred in S9 (step ∈) to the back of the cross, overlap course 2, so that the above knitting is repeated to form left-hand and right-hand wales that cross over and over, i.e., a slant top-bottom type mock knit fabric.

Second embodiment

Fig. 5 is a schematic view of the second embodiment, and fig. 3 shows the same position of the stitch groups after transfer, intersection, and overlapping as in the first embodiment, and fig. 6 is a process diagram for knitting the second embodiment.

T0-T4, S0-S4 as in the first embodiment. The difference is that T5-T9 is as follows:

t5, the stitch groups on the front fabric surface after crossing and overlapping each other are transferred to the front needle bed (step δ). In the present embodiment, the left-hand groups b, f, j are shifted to the left by three needles from the back needle bed to the front needle bed, and the right-hand groups c, g are shifted to the right by three needles from the back needle bed to the front needle bed.

T6, the stitch groups are overlapped with each other and the stitch group on the back surface of the fabric is transferred to the front needle bed (step ε). In the present embodiment, the right-hand groups a, e, and i are shifted to the right by three needles from the back needle bed to the front needle bed, and the left-hand groups d and h are shifted to the left by three needles from the back needle bed to the front needle bed.

T7, and repeating the process T1-T4.

T8, the stitch groups on the front face of the fabric are transferred to the front needle bed after crossing and overlapping each other (step δ), and in this embodiment, the right crossing groups d and h are transferred to the front needle bed by three needles to the right from the rear needle bed, and the left crossing groups c and g are transferred to the front needle bed by three needles to the left from the rear needle bed. Note that in T8, reference is made to fig. 3 by the shifted coil group a and coil group E.

T9, the stitch groups on the back surface of the fabric are transferred to the front needle bed after crossing and overlapping each other (step ∈), and in the present embodiment, the left crossing groups a, e, and i are transferred to the front needle bed by three needles to the left from the back needle bed, and the right crossing groups b and f are transferred to the front needle bed by three needles to the right from the back needle bed. Note that coil set a and coil set j are shifted out in T9, see fig. 3.

In effect, T1-T6 complete the knitting of the 1 st cross, overlapping course of FIG. 5; the knitting of the 2 nd cross, overlap course of fig. 5 is completed by T7-T9, and the knitting of the other cross, overlap courses of fig. 5 is the same as the knitting process of T1-T9, with care only being taken to have sets of stitches moved in and out.

In T5-T6, the left crossing groups b, f, j and the right crossing groups c, g are transferred to the front of the fabric of the crossing/overlapping course 1 at T5 (step. delta.), and the right crossing groups a, e, i and the left crossing groups d, h are transferred to the back of the fabric of the crossing/overlapping course 1 at T6 (step. epsilon.), in T8-T9, the right crossing groups d, h and the left crossing groups c, g are transferred in T8 (step delta) to the front of the fabric of the crossing and overlapping course 2, and the left crossing groups a, e, i and the right crossing groups b, f are transferred in T9 (step epsilon) to the back of the fabric of the crossing and overlapping course 2, so that the knitting is repeated, the left transfer wales and the right transfer wales can be formed, and are mutually crossed and overlapped, namely the knitted fabric knitted by the mat imitating shape with two upper and two lower inclined parts is formed.

As can be seen from the above two embodiments, the knitting of the regular course and the enlarged course is completely the same, i.e. the steps α, β and γ are completely the same, but the difference lies in the different order of crossing and overlapping between the stitch groups, and actually, which of the right crossing group or the left crossing group is transferred first and which is transferred later can be arbitrarily selected, so that more other patterns with oblique mat knitting can be designed according to the needs.

The above-mentioned twisted structure of the woven mat is selected to be 3 × 3, but in practice, for example, 3 × 2, 2 × 2, 4 × 2, 4 × 3, etc. may be selected.
