Abstract

The invention discloses a yarn laying triangle for changing the technical structure of knitted fabrics for a circular knitting machine and application thereof. The yarn-laying triangle for changing the technical structure of the knitted fabric for the circular knitting machine has an ingenious structure, is positioned between a half needle and a needle outlet, can remove the needle latch of the previous path of the coil without removing the loop, and lays the other yarn into the coil, so that the yarn-laying triangle can break the technical structure that the original fabric only has three layers, and is added to four or five layers of fabric, so that the fabric is more fluffy and thick, and the practicability is high.

Description

Yarn laying triangle for changing knitted fabric process structure for circular knitting machine and application thereof

Technical Field

The invention belongs to the field of textiles, and particularly relates to a yarn laying triangle for changing the technical structure of a knitted fabric for a circular knitting machine and application thereof.

Background

Along with the improvement of living standard of people, the requirements on the performance and the appearance of the garment fabric are higher and higher, and the fabric produced by the existing process triangle can not meet the requirements. For example, in the former knitting process, only a flat needle represents that the symbol is "-", a half needle represents that the symbol is "U.N", and a needle outlet represents that the symbol is "V.N", as shown in figure 1, the former triangular arrangement can only open three layers of fabrics, the 1 st and 4 th paths are connected, the 2 nd, 3 rd, 5 th and 6 th paths are surface layers, and the fabric surface is not fluffy and thick enough.

Disclosure of Invention

The invention aims to provide a yarn laying triangle for changing the technical structure of a knitted fabric for a circular knitting machine and application thereof.

The invention is realized by the following technical scheme:

the yarn laying triangle for changing the technical structure of the knitted fabric for the circular knitting machine comprises a bottom plate, straight grooves sequentially arranged on the bottom plate and upward convex triangular grooves straightly connected with the straight grooves, wherein the upper parts of the triangular grooves are also of triangular structures.

The technical triangle is arranged between the half needle and the needle outlet, the function of the triangle is to remove the previous loop from the latch without removing the loop, and pad the other yarn into the loop.

The crochet needle is arranged on the yarn laying triangle, and the process is as follows:

step one, ring withdrawing: moving the old loop under the hook to the needle bar under the latch;

step two, lapping yarns: placing the yarn cushion under the needle hook and above the opened needle latch;

step three, carrying yarn: introducing the yarns on the mat under the hook;

fourthly, translation: the crochet hook is translated until moving out of the yarn laying triangle, so that the laying yarn does not finally form a loop in the yarn laying triangle to form a skip stitch, and the old loop is separated from the latch but not separated from the loop.

The invention also discloses an application of the yarn laying triangle for changing the technical structure of the knitted fabric for the circular knitting machine, which is used for producing the knitted fabric on the circular knitting machine.

The beneficial effects of the invention are:

the yarn-laying triangle for changing the technical structure of the knitted fabric for the circular knitting machine has an ingenious structure, is positioned between a half needle and a needle outlet, can remove the latch of the previous loop without removing the loop, and lays the other yarn into the loop, so that the yarn-laying triangle can break the original technical structure of only three layers of fabric, and is added to four or five layers of fabric, so that the fabric is more fluffy and thick, and the practicability is high.

Detailed Description

As shown in fig. 2-8, the yarn laying triangle for changing the technical structure of the knitted fabric for the circular knitting machine comprises a bottom plate 1, a straight groove 2 and an upward convex triangular groove 3, wherein the straight groove 2 and the upward convex triangular groove 3 are sequentially arranged on the bottom plate 1, and the upper part of the triangular groove 3 is also provided with a triangular structure 4.

It is used in knitting machines (circular machines), which the inventor has named as lapping triangles, the symbol being defined as "

", the structure is shown in FIG. 2.

The yarn-laying triangle is positioned between the half needle and the needle outlet, the triangle has the functions of removing the previous loop from the latch without removing the loop, and laying another yarn into the loop. The specific process of the produced technology is knitting technology (2 nd edition) mainly knitted by Haqingyu and Liu Xiaodong, second weft knitting, a looping process (knitting method) of a first section (second) weft plain stitch on a latch needle weft knitting machine, and a looping process and explanation of a 2-2-7 weft plain stitch on the latch needle weft knitting machine, wherein when the knitting method is used for weaving the weft plain stitch on the latch needle weft knitting machine, 1-7 processes of loop withdrawal, yarn laying and yarn banding are sequentially finished, but the last 8-10 processes of closed looping are not finished, and the weft plain stitch is directly translated out without closed looping, so that the effects of no loop and no loop skipping are formed. The running path of the crochet needle in the yarn laying triangle of the embodiment of the invention is shown in fig. 3, and the yarn laying triangle structure thereof is seen as a mirror image of that in fig. 2, because the yarn laying triangle needs to be buckled inwards to form a part of a circular track after being put into a technical triangle fixing groove on a circular knitting machine, and thus the running direction of the crochet needle in the yarn laying triangle is seen as a mirror image of that in fig. 2.

Specifically, the crochet needle is arranged on the yarn laying triangle, and the process sequentially carried out is as follows, as shown in fig. 4:

step one, ring withdrawing: the old loop under the hook is moved to the shank under the latch, as shown by

needles

4 and 5;

step two, yarn laying: laying the yarn a under the hook and above the open latch, as shown by the

needles

5 and 6, by means of the relative movement of the yarn guide and the knitting needle;

step three, carrying yarn: the yarn on the mat is introduced under the hook, as shown by needle 7;

fourthly, translation: the crochet hook is translated until moving out of the process triangle, so that the lapping yarn does not form loops in the process triangle to form skip stitches, and the old loops are separated from the latch but not separated.

The yarn laying triangle for changing the technical structure of the knitted fabric for the circular knitting machine is used for producing the knitted fabric on the circular knitting machine.

One example of a knitted fabric that can be knitted using the inlay cam of the present invention is shown in fig. 5: the No. 1 and No. 2 are connected, the No. 4 and No. 6 are surface layers, the No. 3 and No. 5 are added, and one layer or two layers are added as sub-layers on the basis of the original fabric after a yarn laying triangle is used, so that the thickness of the fabric is improved, and the fabric is more fluffy.

As shown in fig. 6, 7 and 8, respectively, are schematic views of examples of knitted fabrics that can be produced by using the yarn laying cams of the present invention.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
