Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a Wilton carpet, particularly a pile fabric having a so-called Kinkasan pile structure in which a pattern is formed on the pile surface by a mixture of cut pile and loop pile. be.

[Prior Art] In pile fabrics with this type of Kinkasan weave, the ground weave is composed of the interlacing of the ground warp and the ground weft inserted between the ground warp, and the ground warp connects the ground weft vertically. It is called Futakoshi weave, Mitsukoshi weave, etc. depending on how many ground wefts it crosses before going under the next ground weft.

As for plain or patterned textures where the entire surface is cut pile or loop pile, the Mitsukoshi texture as illustrated in Figure 5 is common, but as for the so-called Kinkasan pile where cut pile and loop pile are mixed, this Those using the Mitsukoshi organization have not been put into practical use.

That is, when Kinkasan pile is woven using the Mitsukoshi weave, as shown in Figure 6, at the same time as the ground weft B' is driven under the core warp Y', the cut pile wire Cw' and the loop pile wire Rw are weaved. ′ are inserted alternately, so there are also four ground wefts A′ and B′ between the cut pile Cp′ and the loop pile Rp′, resulting in a large gap and the pile density becoming too coarse.

For this reason, the Futakoshi structure as shown in FIG. 7 has conventionally been common as the Kinkasan pile structure.

[Problem to be solved by the invention] However, in the case of the pile structure described above, the pile warp
Although P' is pressed by the upper two ground wefts A' and A' to form a pile, as shown in Figure 8, cut pile Cp' and loop pile Rp' are located between the same wefts. They are not formed and appear staggered, and as a result, the outline of the pattern formed by the cut pile Cp' and the loop pile Rp' appears blurred. In particular, when a loom that has been used to weave Mitsukoshi pile fabrics is used to weave Kinkasan pile fabrics based on the Futakoshi structure, changing the structure of the loom is extremely troublesome and time-consuming.

Furthermore, in the Kinkasan pile organization,
As seen in Japanese Patent Application No. 57-77352, there are some piles in which loop piles and cut piles are formed in the same row, that is, between the same wefts. Since the pile is formed while being held down by a single ground weft, the pile density is reduced, but the pile tends to become unstable, especially in the cut pile part, which tends to fall out, resulting in poor durability. become.

In view of the above, in the present invention, the pile warp is held down by two ground wefts, and cut piles and loop piles are formed in series between the same ground wefts, and the outline of the pattern is The purpose of the present invention is to provide a Kinkasan pile fabric which is clear and has excellent durability, and whose structure can be easily changed from the Mitsukoshi structure.

[Means for Solving the Problems] The present invention incorporates pile warp threads into a ground texture formed by intersecting ground weft threads inserted above and below the core warp threads, and forms cut pile and loop pile on one side with these pile warp threads. In order to solve the above problems, we decided to adopt the following configuration in a pile fabric formed with:

The ground texture is such that the ground weft A is driven above the core warp Y when no wire is inserted, and the ground weft B is driven below the core warp Y at the same time as the wire is inserted. A1, B1, B2, A2
The ground warp W1 of the two types of ground warp W1 and W2 is repeatedly driven in the order
1, B2, the other ground warp W2 is the ground weft A2, B
1, the ground wefts A1, A
2, B1, and B2, and the pile warp P1 and P2 are the upper ground weft A.
2. It goes under A1 and is locked to the ground structure, and is selectively pulled upwards depending on the pattern each time the lower ground weft B1 or B2 is inserted,
A pile Cp or Rp is formed by the cut pile wire Cw inserted at the same time as the ground weft B1 is driven and the loop pile wire Rw inserted at the same time as the ground weft B2 is driven, and as a result, the cut pile Cp and the loop pile Rp are the same. It is characterized by being formed in series between the ground wefts A1 and A2.

[Function] In the pile fabric of the Kinkasan structure of the present invention having the above configuration, each pile warp P1, P2 has 2
The book is held down by the weft threads A1 and A2,
Moreover, the ground warp threads W1 and W2 are alternately hung on the ground weft threads A1 and B2 or A2 and B1 one by one, and the ground weft threads A1, A2, B1 and B2 are tight and the ground texture is firm. , each pile warp P1,
P2 is reliably held in an upright position with good stability, and the cut pile portion is also excellent in preventing it from coming off.

Moreover, since the cut pile Cp and the loop pile Rp are formed in series between the ground wefts A1 and A2, the outline of the pattern pattern formed by the cut pile Cp and the loop pile Rp appears clearly.

[Example] Next, an example of the present invention will be described based on the drawings.
Figures 1A and 1B are organization diagrams before and after beating showing the formation state of cut pile and loop pile and insertion state of ground weft of the pile fabric according to the present invention;
The figure is a schematic diagram of the pile surface after weaving, and FIG. 3 is a partially enlarged perspective view showing the pile surface. In the figure, W1 and W2 are the ground warp, Y is the core warp, A1 and A2 are the ground weft that are driven above the core warp Y when the wire is not inserted, and B1 and B2 are below the core warp Y when the wire is inserted. These are the ground wefts that are driven into the side, and these ground wefts A1, A2 and B1, B2
A cored ground texture is formed by the interlacing of the ground warps W1 and W2, and the pile warp threads P1,
P2 is woven to form cut pile Cp and loop pile Rp on one side.

In particular, in the present invention, as shown in FIG. Based on the so-called Mitsukoshi weave that goes below, among the three ground wefts A and B that the ground warps W1 and W2 cross, one of the two upper ground wefts A is alternately used By intermittently inserting two ground wefts into every two upper ground wefts A (the ground wefts to be intermittent are indicated by ), the ground wefts A1, A2 and B1, B2 are changed into A1, B1,
Repeat in the order of B2 and A2 and type ~, thereby turning one of the two types of ground warp W1 and W2 into the ground weft A1 and B2 as shown in figure B.
The other ground warp W2 is alternately applied to the ground wefts A2 and B1 to form a ground texture intertwined with the ground wefts A1, A2, B1, and B2.

Further, at the same time as the lower ground wefts B1 and B2 are driven, for example, the cut pile wire Cw is inserted simultaneously with the ground weft B1, and the loop pile wire Rw is inserted simultaneously with the ground weft B2.
A cut pile and a loop pile are formed by the pile warp P1, P2, and the pile warp P1, P2 is formed by the upper ground weft A2, A by the intermittent insertion of the ground weft A based on the above-mentioned Mitsukoshi organization.
1 and is locked to the ground structure by the ground wefts A1 and A2, and is selectively pulled upwards depending on the pattern each time the lower ground weft B1 or B2 is driven, and the cut pile wire A cut pile Cp or a loop pile Rp is formed over either Cw or the loop pile wire Rw.

In the case of the figure, the pile warp P1 is a cut pile wire inserted when driving the ground weft B1.
A cut pile Cp is formed by going over the top of Cw, and the pile warp P2 goes over the top of the loop pile wire Rw when driving the ground weft B2 to form a loop pile Rp.
In addition to this, a loop pile can be formed by the pile warp P1, and a cut pile can be formed by the pile warp P2.

Then, by beating each time the ground weft is inserted, the ground texture becomes tighter, resulting in a texture as shown in Figure 1B, and the cut pile Cp and loop pile Rp formed as described above are between the same ground wefts A1 and A2. They will be formed in series.

In this pile fabric, as shown in FIG. 2, each pile warp P1, P2 has two ground wefts A
1, held by the ground tissue while being held down by A2,
A cut pile Cp and a loop pile Rp are formed, and since the ground warp yarns W1 and W2 intersect in an X shape and are hung on the ground weft yarns A1, B2 or A2, B1, the ground weft yarns A1, A2, B1, B2
The pile warp yarns P1 and P2 are firmly held in the ground structure in an upright state with good stability, and there is no fear of them falling out in the cut pile portion.

Moreover, the above-mentioned cut pile Cp and loop pile
As shown in Figure 3, Rp is formed in series between the same ground wefts A1 and A2 for every two ground wefts on the upper side, so the boundary between cut pile and loop pile is clear, and therefore gold The outline of the pattern created by cut pile and loop pile peculiar to Mt. Kazan clearly appears, and a beautiful Mt. Kinka pile fabric can be obtained.

FIG. 4 shows a part of the intermittent insertion device for intermittent insertion of the ground weft mentioned above. In the same figure, 1
0 is the picking stick, 11 is the picking tappet, 12 is the picking arm, and spring 1
A connecting rod 1 is urged in the direction of the arrow by 3 and connected with a pin to the side surface of the tappet 11.
When the support member 14 rotates due to the rotation of the picking tappet 11, the picking arm 12 becomes rotatable in the direction in which the spring is biased. Become. Reference numeral 15 denotes a substantially L-shaped locking member that is rotatable around a support shaft 16, and has a claw portion 15 at one end.
a engages with a protrusion 17 on the arm 12 to restrict rocking, and this claw portion 15a engages with a protrusion 17 on the arm 12.
When the arm 1 is separated from the
A picking stick 10 connected to 2 swings to perform the picking operation.

In particular, in this embodiment, a cylinder mechanism 18 such as an air cylinder is connected to the other end 15b of the locking member 15 as a means for operating the locking member 15a in accordance with the shuttle timing. The locking member 15 is rotated by the forward and backward action of the output shaft, and this cylinder mechanism 18 is operated appropriately in accordance with the shedding movement of the loom by electric signals etc. to perform the shuttle throwing according to the pile structure described above. .

That is, at the intermittent point indicated by A in FIG. 1, the cylinder mechanism 18 is not operated;
The claw portion 15a is held in a state where it is locked with the protrusion 17 so that no shuttle action is performed, and the cylinder mechanism 18 is operated at other ground weft locations to lock the claw portion 15a.
is detached from the protrusion 17 to perform a shuttle action, and the ground wefts A1, A2, B1, and B2 are inserted into their respective predetermined positions, thereby driving the structure shown in Fig. 1A above. It will be done.

Of course, it is also possible to control the shuttle throwing by rotating the locking member using a conventional mechanism or other means without using the cylinder mechanism described above, but as described above, it is possible to control the shuttle throwing by rotating the locking member. If the forward and backward movement is performed by a signal, the equipment configuration is simple and computer control becomes easy.

[Effects of the Invention] As described above, in the pile fabric of the present invention, the pile warp is in a state where a pile is formed every two of the upper ground wefts, and is pressed by the two ground wefts, and Because the ground structure is solid, it is firmly held and maintained in a stable upright position, preventing the cut pile from coming off and providing excellent durability. Moreover, the cut pile and loop pile are lined up in series between the same ground wefts, so the outline of the pattern pattern created by the cut pile and loop pile appears clearly, making it extremely beautiful and high-class for this kind of Kinkasan texture pile fabric. You can get a product with a good feel.
