Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fabric tape with loops for use in pull-up curtains, which has excellent dimensional stability and strength of the loop portion, and a method for manufacturing the same.

(Prior Art) In recent years, pull-up curtains that can be pulled up with folded portions 2 formed in multiple stages, as shown in FIGS. 4 to 6, have become popular. The pull-up curtain is made by attaching a tape with loops (a guide ring is attached to the loops as necessary) vertically to an appropriate part on the back side of the curtain fabric, and attaching the tape to the loop or the guide ring. The operating string is inserted through the curtain and the lower end of the operating string is fixed to a loop or a guide ring, and by operating the operating string, the curtain can be pulled up as described above.

By the way, examples of tapes with loops attached to curtain fabric include those shown in FIGS. 18 and 19. Looped tape a1 shown in Figure 18
The entire tape is formed as a woven fabric, and the weft b is woven in only half of the tape width at a required portion, and the other half that is not woven forms a loop c1. Further, the tape with loops a2 shown in FIG. 19 is entirely formed as a knitted fabric, and loops c2 are formed at required portions by pattern yarns d knitted into the ground structure.

(Problems to be Solved by the Invention) However, in the case of the looped tape a1 as the fabric, the weight of the folded portion e formed when the curtain is pulled up is applied to the loop c1 portion (the sixth (see figure), the woven part f of the weft yarn forming the loop c1 tends to be pulled out, and as a result, a tissue collapse g as shown in Fig. 18 occurs in the loop c1 portion, reducing the durability of the looped tape. The problem was that it was easy to invite and,
As the curtain fabric forming the pull-up curtain becomes thicker, the weight of the folded portion e increases accordingly, and this problem becomes more serious.

On the other hand, in the case of the looped tape a2 as the knitted fabric, due to the characteristics of the fabric, the length direction (the first
There is expansion and contraction in the direction of symbol F shown in FIG. 9), and the longer the tape length, the greater the amount of expansion and contraction. Therefore, when the mesh tape a2 is attached to the curtain fabric by sewing, welding, etc. (a certain appropriate tension is applied to the tape, and the tape is stretched, the attachment operation is performed). When the tension applied at the time of installation is released and the tape returns to its original state, unnatural wrinkles will occur in the curtain due to shrinkage of the tape. There was a problem that caused the value to drop.

The object of the present invention is to provide a fabric tape with loops for a pull-up curtain and a method for manufacturing the same, which can solve the above-mentioned problems of the conventional tape with loops.

(Means for Solving the Problems) The fabric tape with loops for a pull-up curtain according to the present invention (hereinafter referred to as the tape with loops) constitutes a pull-up curtain that is pulled up with folded portions formed in multiple stages. In this case, the tape is attached to a curtain fabric, and the required number of warp threads forming the tape base material 5 are placed on one side of the tape base material 5 formed as a woven fabric at required intervals in the length direction. A loop 9 is formed in a protruding manner and has a textile structure (various textile structures such as a plain weave structure and a bag weave structure) intertwined with the weft threads forming the curtain 5. It is characterized in that it can be used for inserting a string or for attaching a guide ring through which the operating string can be inserted.

The manufacturing method for manufacturing the looped tape (hereinafter referred to as the manufacturing method) is such that a tape 9 having a woven texture is placed on one surface of the tape base 5 formed as a woven fabric in the lengthwise direction of the tape base 5. When forming protrusions at intervals, two types of warp threads are used: a first warp thread 10 that participates in loop formation and a second warp thread 11 that does not participate in loop formation. warp 10,1
1 and the weft 20, and in the loop forming part 13, the progression of the second warp 11 is stopped and only the first warp 10 is advanced, and the weft 2
It is characterized in that the loop 9 is formed by intersecting only the first warp yarn 10 and the first warp yarn 10.

(Example) Examples of the present invention will be described below based on the drawings.

In Figs. 1 and 2, the looped tape 1 of the present invention
is attached to the curtain fabric 4 when configuring the pull-up curtain 3 (see FIGS. 4 to 6) that is pulled up with folded parts 2 formed in multiple stages (see FIG. 3), Loops 9 having a woven texture are formed protruding from one side 6 of a tape base 5 formed as a woven fabric at required intervals in the length direction using warps 7 forming the tape base 5. In this embodiment, two types of warp threads 7 are used: a first warp thread 10 dedicated to forming loops 9 and a second warp thread 11 dedicated to forming ground texture. 1 warp 10 is
In the part 12 other than the loop forming part, it is woven together with the second warp 11 dedicated to forming the ground texture,
In the loop forming portion 13, a round cord-like loop 9 having, for example, a bag structure is formed by interlacing with the weft. The types of warp and weft yarns forming the tape with loops 1 are not particularly limited, but when forming a pull-up curtain using thin fabric, it is necessary to prevent the tape with loops 1 from being seen through as much as possible. , such as polyester monofilament, etc.
It is best to use transparent warp and weft threads. In addition, when a rigid warp such as monofilament is used, the folded part can be made plump when the pull-up curtain is pulled up, which makes the appearance of the pulled-up curtain even more attractive. It's nice to be able to make something.

The looped tape 1 formed in this way can be attached to a pull-up curtain 3, for example, as shown in FIG.
It is attached to an appropriate part of the back surface of the curtain fabric 4 forming the curtain fabric 4, for example, by sewing, welding, etc. so as to extend in the vertical direction. Note that a guide ring 15 is attached to each loop 9 of the looped tape 1, if necessary, as shown in FIGS. 1 and 3. Therefore, the operation string 16 for raising and lowering the pull-up curtain 3 is inserted through the loop 9 or the guide ring 15 attached to the loop 9, and its lower end 17 is fixed or engaged with the loop 9 or the guide ring 15, so that the operation can be performed. Winding up the operating string 16 by a winding device in the box 19;
If rewinding is possible, a pull-up curtain 3 will be constructed that can be raised or lowered in accordance with the operation of the operating string 16 (see FIGS. 4 to 6). Note that the lower ends of each operating group 16 may be connected to each other by a rigid bar. The pull-up curtain 3 is
When it is lowered, it looks no different from a normal curtain (see Figure 4).
When the operating string 16 is wound up, the folded portion 2 is pulled up in a multi-staged state, as shown in FIGS. 5 and 6.

Next, a method for manufacturing a looped tape according to the present invention will be explained.

That is, the manufacturing method of the present invention uses two types of warp threads 7: a first warp thread 10 that participates in loop formation and a second warp thread 11 that does not participate in loop formation. As shown, the first
The warp threads 10 and the second warp threads 11 are wound around independent cross beams. In this embodiment, the first warp threads 10 are used exclusively for forming loops, and the second warp threads 11 are used for forming ground texture, and the second warp threads 11 are arranged evenly over the entire width of the tape. ing. Therefore, as shown in FIG. 7, the first warp threads 10 are in a state opposite to the second warp threads 11, and weaving is started in this state. In the manufacturing method of the present invention, during the weaving, two types of warp yarns 10 and 1 are used in the portion 12 other than the loop forming portion.
1 and the weft, and in the loop forming part 13, the progression of the second warp 11 is stopped, and therefore the winding of the looped tape 1 is stopped, and only the first warp 10 is advanced, Weft and the first warp 1
It intersects only 0. As a result, a tape with loops 1 according to the present invention is formed in which loops 9 having a textile structure (for example, a hollow weave structure, a plain weave structure, etc.) are formed protruding from one surface of the textile tape base material 5 (No. (See Figures 1-2).

In addition, when interlacing the second warp 11 dedicated to forming the ground texture with the weft, when giving shedding motion to the second warp 11 using two types of heddles,
As shown in FIG. 9, raised weft yarns 19a and 19b occur at both ends of the loop 9, and the appearance of the obtained looped tape 1 becomes unfavorable. Therefore, in this embodiment, such lifting of the weft yarn is prevented by the method described below. That is, as shown in FIGS. 10a and 10b, the second warp 1
The row 1 is divided into a right row 20 and a left row 21 with the longitudinal center line as a boundary, and two types of healds 22 and 23 are made to correspond to the right row 20, and the left row 2
Two types of healds 25 and 26 are made to correspond to each other, and different shedding movements are applied to the right side row 20 and the left side row 21 as necessary. For convenience of explanation, loop 9
is a plain weave structure, and in order to form the loop, 2
Different types of healds 27 and 29 are made to correspond to each other.

However, in the portion 12 other than the loop forming portion, the healds 22, 25, and 27 are simultaneously moved up and down, and the healds 23, 26, and 29 are moved up and down at the same time, as shown in FIGS.
are simultaneously moved up and down, the first warp 10 and the second warp
A shedding motion is applied to the warp threads 11 of. Immediately before loop formation, the healds 22 and 25 are located at the top, the healds 23 and 26 are located at the bottom, and both the right row 20 and the left row 21 are open, as shown in FIGS. 10a and 10b. In this state, weft insertion 30 is carried out. In addition, at this time, the healds 27 and 29 that give shedding motion to the first warp threads 10 are located above and below.

During the next weft insertion, as shown in FIG.
2 and 23 are both located at the bottom, and in this state weft insertion 3
1, wefts are woven in the right row 20 and the first warp 10 portion (numerals 30a, 30
b) However, in the left row 21, the weft that has been inserted is removed from the left row 21. Therefore, lifting 19a of the weft yarn at one end of the loop 9 as shown in FIG. 9 is prevented. In addition, in the right row 20, since the shed is in a closed state, the inserted weft threads are not woven into the warp threads 11 of the right row 20 (see numeral 32). In order to prevent the floating of the weft yarns 19a, it is important that the weft yarns inserted as shown in FIG. When putting 30,
The healds 25 and 26 may both be located at the bottom, and in this state the weft insertion 31 may be carried out as shown in FIG. 11a.

The subsequent weft insertion 33 is carried out on the second warp 1 of the right row 20 and the left row 21, as shown in FIGS. 12a and 12b.
1 is closed and only the first warp threads 10 are shedding, thereby forming the loop portion 9a.

At the stage when the loop portion 9a is formed to the required length, the other end of the loop portion 9a is fixed to the ground fabric to form the required loop 9. At the time of insertion, the healds 22 and 2 are
7 is located on the top and the healds 23, 25, 2
6 and 29 are located at the bottom, and weft insertion 35 is carried out in this state.

During the next weft insertion, as shown in FIGS. 14a and 14b, the healds 22, 23, 27, and 29 are reversed and the healds 25 and 26 are separated into upper and lower parts. When weft insertion 36 is carried out in this state, the last weft involved in loop formation leaves the loop portion 9a and is woven into the right row 20 (35).
a, and therefore, lifting 19b of the weft yarn at the other end of the loop 9 as shown in FIG. 9 is prevented.

Thereafter, as shown in FIG.
A shedding motion is applied to the warp threads 10 and the second warp threads 11 to perform weft insertion 37.

Note that, as shown in FIG. 16, the first warp threads 10 are held down by a presser 39 that is biased upward or downward (downward in FIG. 16) by a moderate spring action, so that the first warp threads 10 are not looped. Part 9a
During formation, the loop portion 9a (see the one-dot chain line shown in Fig. 17), which is in a folded state when the reed is beaten, immediately returns to the stretched state in a straight line (see Fig. 17) as the reed moves away from the fabric. Therefore, weaving of the loop portion 9a can be performed without any problem.

Note that when the first warp threads 10 and the second warp threads 11 are arranged facing each other as in this embodiment, all of the loops 9 naturally appear on one surface of the tape base material 5. This is preferable because it is possible to improve the strength of the loop portions that are subjected to concentrated loads during weaving, but warp rows having approximately equal density are formed by the first warp yarns 10 and the second warp yarns 11. The first warp 10 and the second warp 11
(see FIG. 8) is not excluded in the manufacturing method of the present invention.

(Effects of the Invention) The tape with a loop of the present invention is formed by forming a protruding loop having a woven texture on one side of a textile tape base material, so that the loop having the woven texture is hard to wear and has high strength itself. Excellent. Further, since the loop is formed using the warp threads forming the tape base material, and therefore both ends thereof are firmly integrated with the tape base material, the load carrying capacity of the loop portion is extremely large. In addition, the tape base material having a woven structure has almost no expansion and contraction in the length direction, and the tape with loops has excellent dimensional stability.

For this reason, not only is there no disadvantage that the load applied to the loops causes tissue collapse in the loop portions, which reduces the durability of the tape, as in the conventional woven tapes mentioned above, but also There is no inconvenience such as the occurrence of unnatural wrinkles in the curtain due to the expansion and contraction of the tape, as is the case with adhesive tapes.

Furthermore, since the loop is formed as a woven fabric, it is easy to attach the guide ring to the loop.

The manufacturing method of the present invention uses two types of warp threads, a first warp thread that participates in loop formation and a second warp thread that does not participate in loop formation, and has a basic configuration that gives independent movement to these warp threads. , it is possible to manufacture high-quality looped tape with high productivity.
