Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing napped knitted products using a double needle bed type warp knitting machine.

When knitting a raised product with a conventional double side bed type warp knitting machine,
Warp knitting σ) Properties 2. Vertical pattern, swing pattern σ) Pattern is knitted b.
However, the horizontal pattern was difficult to knit.

Looking at this with regard to the Karl Mayer blanket knitting machine, which is a type of double-layered raschel knitting machine, the Karl Mayer blanket knitting machine normally has two opposing Kenpo knitting machines, as shown in Figure 1.
．． 4 opposed knitting needles 6.8, in addition to a reed for knitting the ground structure (not shown), a reed for incorporating the raised tip, that is, a pile reed 10
1" one by one. Pile reed 10 has opposed knitting needles 6.8
The operation is performed as shown by the solid line 12 in FIG. Therefore, when moving from one knitting (16 to 11 knitting thread 8) of the facing knitting fI + 6.8, make a loop of the standing thread by twisting the standing wool yarn in one transfer thread 6, and vice versa. When moving from button 8 to knitting button 6 on the - side, the other σ) knitting button 8 is entwined with the standing yarn to form a loop of the standing yarn. Opposing (tfI planning 6,
8 In 2, the opposing ground organization is created by a reed (not shown).
Due to the operation of the pile reed 10, the raised yarns are knitted into each part of the fabric 7, and by repeating this operation, the two-sided fabric 14 is knitted as shown in FIG. 6-4.
A raised yarn 18 is knitted across the 16 spaces in a zigzag pattern. The ground structures 14 and 16 are separated by cutting the napped yarn 18 at its center, resulting in two napped knitted products.

In this method of manufacturing napped cotton products, when creating a pattern, by changing the color of the napped yarn fed to the pile reed 10 in a predetermined section, the napped yarn in the corresponding one mesh can be changed. The colors differ in the vertical direction, as shown in Figure 4 (
As shown in Fig. 4(a), the vertical handle 20 is formed, and as a result of shaking the pile reed 10 from side to side, the different colored parts of the raised pile become zig-sag in the vertical direction, as shown in Fig. 4(a). A swing pattern 22 is formed as shown in FIG.

However, in the conventional manufacturing method of napped knitted products,
The napped yarn fed to each pile reed 10 is the same one, and must be replaced regularly with another napped yarn to form a long pattern. I couldn't.

In the past, there was a Karl Mayer knitting machine in which two pile reeds were provided for each opposing knitting needle, but this i], (r22 sheets σ
) The reeds are operated at the same time to double the density of the raised pile, making it possible to produce velvet-like car seats, heavy clothing, etc.
), the two pile reeds were not operated separately, and the above-mentioned knitting = J function, but the horizontal pattern could not be knitted.

An object of the present invention is to provide a method for producing a napped knitted product using a double side bed type warp knitting machine that is capable of knitting a horizontal pattern σ).

According to the present invention, there is a distance of 1-! on the opposing barrel side of the opposing needle bed. Two reeds are provided on each opposing body side for knitting the standing yarn into the fabric of the opposing fabric that is being knitted, and when one reed is operating, the other reed is not operated, and the other reed is In this way, the reed is knitted across the two fabrics, and the raised yarn is cut into two raised knitted products. A method for manufacturing a napped knitted product using a floor-type warp knitting machine is provided. To explain, the illustrated embodiment is an example in which the present invention is implemented using a Karl Mayer blanket knitting machine, as in the case of the 4tE manufacturing method described above.

In the manufacturing method of the present invention, as shown in FIG.
Diagram for knitting the facing fabric on the facing needle beds 2, 40 and the facing knitting needles 6.8 (-In addition to the reed, the pile reed 30 is a reed for knitting the standing yarn on the facing fabric that is being knitted. ．”
7, the pile reeds 30.32 operate as shown by solid lines 34, 36, 38, 40 in FIG. 6 with respect to the opposing knitting needles 6, 8. do.

That is, the pile reed 30 is
When moving from one trunk side 6 to the other knitting needle 8 of the opposing trunk sides 6, 8, the napped yarn is entwined with one knitting needle 6 to create a loop of napped yarn, and conversely, from the other knitting needle 8 to one knitting needle 6. When moving, the other knitting needle 8 is entwined with the standing yarn to create a loop of the standing yarn. When the pile reed 30 is operating in this way,
As shown in the lower part of FIG. 6 ('7) of the 32-year-old bail reed, the yarn simply moves idly between the adjacent and opposing knitting buttons and does not form a loop of the raised yarn, that is, is not in operation.

Since the facing fabric is being knitted on the opposing knitting needles 6 and 8 by a reed (not shown), only the pile yarn (with a pile reed of 30σ) is knitted into the facing fabric by such action of the pile reed. Also, as shown in the lower row of FIG. 6(A), when the pile reed 32 operates in the same way as the pile reed 30 described above and is busy, the pile reed 30 operates as shown in the second row of FIG. 6(A).
Like the pile reed 32 mentioned above, it is not operating. Therefore, only the raised yarns of the pile reed 32 are knitted into the facing fabric. By alternately performing the actions shown in Fig. 6 (force) and the actions shown in Fig. 6 (a) of the reed 30.32, the knitted intermediate product In 42, the pile reed 30σ) raised yarn 50 is knitted and twisted across the pile reed 30σ between the two ground structures 46 and 48 in a jig-like pattern, and the pile reed 32
The napped yarn 52 is knitted across the fern AJ dog shape. The pile yarn 50 of the pile reed 30 is simply made from 13 points (2
It only extends to a point.

This intermediate product is separated into two napped knitted products by cutting the napped yarn 50.52 at its center.

Therefore, the raised yarn 50.5 fed to the pile reed 30.32
By changing the color of section 2, etc., the color of the raised hairs of sections 42 and 44 will be different, and as shown in Fig. 8, section 4
2.44 The horizontal pattern 54 according to the color of the raised yarn 50°52,
56 patterns are formed. In the above embodiment, the opposed knitting needles 6 and 8 are knitted at a speed of 20 knitting patterns per minute.
It is moving downward at a high speed of 0 to 250 times, and under such high speed operation, the pile reed 30°32 Fig. 6 (7)
In order to instantly and smoothly convert the action shown in Fig. 6(a) to the action shown in Fig. 9, the pile reed 30.3 is used as shown in Fig. 9.
It is preferable to provide a tension adjustment device 60 for adjusting the tension of the napped yarn 50, 52 fed to the yarn 2.

The tension adjustment device 60 is provided with a fixed passive feed roller 66.68 which is always driven at a constant rotational speed upstream of the fixed idler roller 62.64, and has a fixed idler roller 62.6.
A movable weight roller 70.72 is provided between the constant negative polarity feed roller 66.68 and the constant negative polarity feed roller 66.68.

When the pile reeds 30 and 32 operate as shown in FIG. The weight roller 70 raises the weight roller 70 and feeds the yarn to the pile reed 30 with a certain regulated tension, and the raised yarn 52 of the pile reed 32 is lowered by its own force. - Pile reed 3 while maintaining constant tension
Yarn feeding to 2 is stopped. When changing from the operation 1 shown in FIG. 6(A) to the operation shown in FIG. 6(B), that is, when the pile reed 30 stops operating and the pile reed 32 starts operating, , the feeding of the napped yarn 50 to the pile reed 30 is stopped, but since the weight roller 70 starts to descend under its own weight, the napped yarn 50 maintains its constant tension without sagging, and The raised yarn 5 starts feeding yarn to the pile reed 32
2, the lowered weight roller 72 is on top! 1, the υ tension hardly fluctuates.

Therefore, at points A and B in Fig. 7, the napped yarn that is in progress of knitting stops instantaneously, and the napped yarn that is not knitting is instantly inserted, and at this time, the tension of each chamber yarn is is maintained constant and the same, uniform napped knitting is possible.

Therefore, according to the method for producing a napped knitted product using a double needle bed type warp knitting machine of the present invention, since the napped yarn is knitted for each opposing knitting needle, σ)
Two reeds are provided, and when one reed is in operation, the other reed is not in operation, and conversely, when the other reed is in operation, one reed is not in operation to perform the piling stitch. Therefore, it is possible to knit a horizontal pattern, which was previously considered impossible.
