Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of knitting a double-sided pile warp knitted fabric. Conventionally, double-sided pile warp knitted fabrics are knitted using warp knitting machines by forming loop piles of front and back yarns on both sides of the ground fabric using empty needle structures, and by arranging pin needle rows before and after the knitting needle rows. The base of the pile yarn is knitted into the ground texture formed by knitting with rows of knitting needles,
There is a method of forming a loop pile by passing the pile yarn around the pin needles.

In the former method of forming double-sided loop piles in warp knitting, the legs of the loop pile on one side of the knitting structure can be fixed to the ground structure by forming stitches integrally with the ground structure. If the loop pile on the other side is to be formed integrally with the ground structure, it can only be formed between adjacent wales, so it is difficult to fix the loop pile by normal stitch formation and to fix it by insert knitting. When knitting a double-sided pile warp knitted fabric using the conventional method, only the loop piles on both sides have different shapes. It could only be made for limited purposes.

In addition, the latter type has a complicated knitting motion and requires a special knitting machine structure, resulting in extremely low knitting efficiency and problems in terms of productivity.

The present invention has been made to solve the above-mentioned drawbacks, and it forms loop piles on the ground texture so that they have the same shape and arrangement on both sides, and also enables knitting in terms of production, for example, using a high-speed double-needle row tricot machine. The purpose of this paper is to provide a method for organizing the data.

The knitting method of the present invention will be explained below based on the drawings. Fig. 1 shows a side view of the main knitting part of a double needle row tricot knitting machine used for knitting a double-sided pile warp knitted fabric; The pile forming yarn 1 is threaded through the ground reed 4 at the front, and 2 is the warp, and the warp 2 is the middle ground reed 5.
3 is a pile forming thread, and the pile forming thread 3 is threaded through a rear ground reed 6, 7,
8 is a sinker, 9 and 10 are pressers, and F
indicates the front needle and B indicates the rear needle.

Next, the knitting structure used in carrying out the knitting method of the present invention will be explained.

FIG. 2 shows an embodiment of the knitting structure, in which the pile forming yarn 1, the warp yarn 2, and the pile forming yarn 3 are connected to the needles F or the rear needle B, except for one yarn, a ground reed 4, a ground reed 5, and a pile forming thread 3. Each thread is threaded through the ground reed 6.

Next, to explain the knitting process, first, the ground reed 5 is one that overlaps three rows of needles to form stitches using the warp threads 2, as shown in the figure.
F ₁ , F ₂ , B ₁ , B ₂ ... indicate the knitting course on each front or rear needle, and in the F ₁ course, stitches are formed by overlapping on the left front needle FN ₁ , and then on the center rear needle. After overlapping to BN ₂ , overlapping to right front needle FN ₃ , and again after overlapping to needle BN ₂ , return to front needle FN ₁ to finish knitting one repeat. Organize by repeating.

Next, the ground reed 4 guides the pile forming yarn 1 to form a loop pile on the back side, first, in the F ₁ course, overlapping is performed with the needle FN ₁ to form a stitch, and in the B ₁ course, the pile forming yarn 1 is applied to the needle BN ₁ . , in the F ₂ course, after overlapping the rows of needles that are consecutively opposite to the needle FN ₁ , in the B ₂ course, the needles diagonally adjacent to the needle FN ₁ are overlapped.
Overlapping is performed on BN ₂ , and then returned to needle FN ₁ and overlapping is completed to complete one repeat knitting, and then this is repeated to knit.

In addition, the ground reed 6 guides the pile forming yarn 3 in order to form a loop pile on the surface, and first, in the F ₁ course, overlaps the needle FN ₂ to form a stitch, and in the B ₁ course, it guides the pile forming yarn 3 to the needle BN ₂ . In the F ₂ course, needle FN ₃ diagonally adjacent to needle BN ₂ is overwrapped to form a stitch, and in the B ₂ course, it returns to the original needle BN ₂ after overlapping. , return to needle FN ₂ and overlapping 1
After completing the repeat arrangement, next repeat this arrangement.

Figure 3 shows the trajectory of the movement of the ground reeds 4, 5, and 6 viewed from above the needle row in the above formation. ₁ , BN ₂ , FN ₃ , BN ₄ , FN ₅ ... by overlapping to form needle loops from the warp 2, and connect sinker loops connected to each formed needle loop in a zigzag pattern to create a ground structure. form.

(B) is the movement trajectory of the ground reed 5, and the needle FN ₁
and Needle BN ₁ are empty needles that do not form stitches.
Overwrapping is performed on BN ₁ , and the pile forming yarn 1 is wrapped around it, and between needle FN ₁ and needle BN ₂ , overlapping is performed integrally with the ground reed 5 to form a pile integrally with the ground texture of the warp threads 2. The legs are fixed by knitting yarn 1, and the above-mentioned stretched portion is not knitted and becomes a loop pile.

(C) is the locus of movement of the ground reed 8, and the needle FN ₂
and needle BN _2, the pile forming thread 3 is wrapped around empty needle FN ₂ with overlapping, and between needle BN ₂ and needle FN ₃ , warp thread 2 is wrapped.
The leg part is fixed by knitting the pile forming yarn 3 integrally with the ground structure, and the stretched part is not knitted and appears as a loop pile.

By the above knitting, the double-sided pile warp knitted fabric shown in Fig. 4 is obtained, and among the needle loops formed by the warp yarns 2, 2B is formed by the rear needle row BN, and 2F is formed by the front and rear needle rows FN. The needle loops 2F and 2B are formed alternately, and each is connected by a sinker loop 2C formed by warp yarns to form a ground structure, and the pile forming yarn 1 is formed on the surface of this ground structure. The loop pile 1 _a bulges out due to the loop pile 2B, and its root is formed as a needle loop 1 _b integrally with the loop pile 2B and is knitted into the ground structure.On the other hand, on the back side, the loop pile 3 _a formed by the pile forming yarn 3 bulges out, and its root is formed integrally with the loop pile 2F as a needle loop _3b , and is woven into the ground structure.

In the above knitting, the warp threads are guided by one row of ground reeds, and the pile forming yarns are guided by two rows of ground reeds, but in another knitting example, the warp threads are guided by one or two rows of ground reeds. By knitting the ground texture and knitting the pile yarn by overlapping over two stitches with a row of ground reeds, it is also possible to make the loop pile continuous on the front and back.
In this case, it is effective when you want to make the fabric weight extremely light.

As described above, the present invention uses a warp knitting machine having a plurality of needle rows, uses the needles in each needle row alternately in front and back, and forms a ground texture by connecting needle loops and sinker loops by warp threads. The knitted fabric is made into a single piece of fabric, and a loop pile is created by wrapping the pile forming yarn using empty needles that do not participate in stitch formation, and the root is fixed to the ground texture by forming stitches together with the warp threads. Accordingly, the height of the loop pile is the same on the front and back sides, and the loop pile is also arranged in the same manner.

As a result, by the knitting method of the present invention, it is possible to efficiently knit a double-sided pile warp knitted fabric in which the pile texture is uniform on both sides.
