Abstract

PURPOSE:To reduce mutual rubbing of warp yarns and obtain a double pile fabric having a high warp yarn density by opening warp yarns for an upper fabric in the upper side of a lancet in picking a weft yarn for the upper fabric and providing a closed opening state of warp yarns for a lower fabric in the lower side of the lancet and reversing the state in picking a weft yarn for the lower fabric to the above-mentioned state. CONSTITUTION:A double pile fabric of 'HITOKOSHl' design (a kind of plain crepe) is woven by alternately picking a weft yarn 14 for an upper fabric 11 and a weft yarn 14' for a lower fabric 11' in each reed beating. When the weft yarn 14 for the upper fabric is picked, an opening 13 by warp yarns (12a) and (12b) for the upper fabric is formed on the upper side of a lancet 16 and an opening is not formed with warp yarns (12a') and (12b') for the lower fabric to provide a parallel state on the lower side of the lancet 16. When the weft yarn 14' for the lower fabric is picked, the warp yarns (12a) and (12b) for the upper fabric are not opened oppositely to the above-mentioned state and formed into a parallel state on the upper side of the lancet 16. An opening 13' by the warp yarns (12a') and (12b') for the lower fabric is simultaneously formed on the lower side of the lancet 16. Thereby, the openings of the warp yarns for the upper and lower fabrics are not formed in the two upper and lower stages and either thereof is in a closed opening state. As a result, fluffing or induction of yarn breakage by mutual rubbing of the warp yarns are prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for weaving double pile fabrics used for vehicle interior materials, upholstery, rugs, etc.

[Conventional technology]

The double pile fabric 11 has upper fabric warp threads 12a to 12b.
The warps 12a' and 12b' for the lower 4 are opened in two stages, upper and lower, and the weft 14 for the upper fabric and the weft 14' for the lower fabric are simultaneously introduced into the openings 13 and 13', respectively. While simultaneously forming a 11" ground weave, the pile yarns 15 are connected, and the connected pile yarns 15 are connected to the upper fabric 11 and the lower fabric 1.
It is cut between the ground textures of 1@, and two pieces are woven at the same time, top and bottom (Japanese Patent Laid-Open No. 147263/1983).

The pile length h-h' is the upper 41 where the pile threads 15 are connected.
1 and the base fabric of the lower fabric 111, and the pile yarn 1
In patterned double pile fabrics, in which the delivery amount of No. 5 is different for each color yarn forming the pattern, one end of Lancera 1-16, which can be called a pseudo warp, is fixed to the heddle side in order to keep the pile length h (hl) constant. A method is adopted in which the tip 17 is pushed out to the front of the fabric and woven into the fabric (Japanese Patent Laid-Open Nos. 54-147263 and 59-53741).

Regarding this lancet 16, the present inventor has completed a device in which the height of the protruding end 17 toward the woven fabric is gradually changed so as to become tapered, thereby making it possible to adjust the pile length in stages. 62
-83889.

The ground weave depends on the number of weft yarns that are thrown in to form one pile 18 in the warp direction; those with one weft are called Ichikoshi weave, those with two wefts are Mitsukoshi weave, and those with three wefts are called Mitsukoshi weave. It is called the Mitsukoshi Organization.

Figure 3 illustrates the Futakoshi organization, which is published in Japanese Patent Application Publication No. 54-147.
263 is also illustrated.

Figure 4 illustrates the Ichikoshi organization, which is published in Japanese Patent Publication No. 59-537.
41 is also illustrated.

As is clear from comparing Figures 3 and 4, in the weaving process of the double pile fabric in which the upper and lower layers are opened and the 14" and 14" wefts for the upper and lower fabrics are input at the same time, Futakoshi and Mitsukoshi In the weave, it is sufficient to open one pile yarn 15 up and down with each beating, but in the case of the -gou weave, two pile yarns 15.
51 must be opened up and down so as to intersect at the front of the fabric.

The warp density of the ground texture is determined by the spacing between the reeds, and it is not possible to use pile threads that are thicker than the gaps between the reeds.

As mentioned above, in the case of the Ichikoshi weave, two pile yarns that are twice the thickness of the Mitsukoshi or Mitsukoshi weave must be passed through the gaps between the reed feathers, so the pile yarn 15 is Although it is necessary to use thinner yarn than in the case of the Futakoshi or Mitsukoshi weave, the pile yarn is made of the same thickness as in the case of the Futakoshi or Mitsukoshi weave, and only the ground weave is made uniform. If you want to create an open weave, use one pile yarn 15 as shown in Fig. 5, and while beating twice, open the warp yarns 12 in two consecutive rows, upper and lower, twice in the same way. 15
The weft for upper fabric 1 is made to move up and down with each stroke.
4 and the weft 14° for the lower fabric must be input separately.

Regarding this point, JP-A No. 61-132654 discloses that each time the weft is not inserted, the warp 12' is opened twice in the same way until the next weft is inserted, and the warp 12a, in which the weft is inserted, is opened twice. 12b is made to perform vertical shedding motion to prepare for the next weft to be introduced.

[Problem to be solved by the invention]

As mentioned above, if you want the pile yarn to have the same thickness as the Futakoshi or Mitsukoshi weave and only the ground weave to have the Ikkoshi weave, open the warp 12 twice in the same way in two consecutive rows. The upper fabric weft 14 and the lower fabric weft 14'' must be input separately for each beating, but in that case, when inputting either the upper or lower weft 14 (14'), the other The weft 14' (14) is not inserted, and the warp 121 of the upper and lower sides where the weft 14' is not inserted.
It would be wasteful to open the warp threads 13a" and 13" when the opening 13" closes with the beating of the reed.
b1 rub against each other (Fig. 6), and since the shedding movement of the warp threads is twice as much as when the upper and lower weft threads 14 and 14" are thrown in at the same time (Fig. 4), the warp threads 13
・131 tends to become fluffy and may cause thread breakage.

[Purpose of the invention]

Therefore, the present invention aims to reduce the rubbing of the warp threads 12 in the weaving process of the double pile fabric 11.
This aims to reduce fuzz and thread breakage.

[Structure of the invention]

That is, the present invention is directed to the center line 0-O' that passes through the fabric 19 and divides the upper and lower cloths 11 and 11 degrees into upper and lower halves. A lancet 16 with $117 protruding from the front 19 of the weaving and the other end fixed at the rear of the heddle is arranged, and the weft 14 for the upper fabric and the weft 141 for the lower fabric are alternately introduced every time the weft is beaten. 1
In the weaving process of step 1, when inserting the upper fabric weft 14, an opening 13 formed by the upper fabric warp 12a and 12b is formed above the lancet 16, and the lower fabric warp 12a' and 1
2b' is a closed opening 2O' without forming an opening 13' and aligned below the lancet H6. When inserting the upper fabric weft 14', the opening 131 formed by the lower fabric warp 12a' and 12b9 is aligned with the lancet 16. It is characterized in that the warps 12a and 12b for the upper cloth are arranged on the upper side of the lancet 16 as a closed opening 20 without forming an opening 13.

In this way, the position where the warp threads 12 are aligned upward or downward to form the closed opening 20 is the position of the warp thread 12a above the opening 13 that will be formed next in the warp thread 12 for the upper fabric, and the warp thread for the lower fabric 12', it is preferable to position the warp threads 12b' below the opening 13' to be formed next.

This is because by doing so, the woven fabric 19 has two warps 12a when the lower cloth warp 12' is closed 2O'.
It is pulled downward by @ and 12b1, but it is pulled upward by a total of two threads, one warp thread 12a and one pile thread 15 (Fig. 1).

On the other hand, when the warp threads 12 for upper cloth are closed 20, they are pulled upward by the two warp threads 12a and 12b, but a total of two threads, one warp thread 12b' and one pile thread 15, are pulled upward. (Figure 2).

In this way, since the fabric is symmetrically pulled upwardly and downwardly by two threads each, the fabric front 19 is stably maintained on the center line o-o'.

〔Effect of the invention〕

As described above, in the present invention, the upper cloth opening 13 and the lower cloth opening 1
Instead of forming the weft 14 (
Since the warp threads 12 (12") of either the upper fabric or the lower fabric that are not inserted at 14°) are closed 20 (20"), (1) the frequency of the warp threads rubbing against each other is halved. For this reason,
(2) The warp becomes less fluffy during the weaving process; (3)
Thread breakage is not induced, and (4) reed beating becomes smooth, thereby (5)
A double-pile fabric 11 with a dense warp density can be efficiently woven using large-count pile yarns 15. (6) The fabric 19 is always kept stably on the center line 〇-〇f between the upper cloth 11 and the lower cloth 11'. For this reason, (7)
The lancet 16 is not distorted vertically, and (8)
The pile length is also uniform, so (9) it is possible to obtain a double pile fabric 11 with a smooth pile surface.

As described above, the present invention is extremely advantageous in weaving a double pile fabric with an Ichikoshi structure.
