Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a novel and special yarn made by combining a bundled yarn and an unbound yarn with a higher hot water shrinkage rate. It concerns interlaced yarns.

<Prior art> It has been well known that by combining yarns with different yarn forms and physical properties, it is possible to obtain a composite yarn with a texture and appearance that cannot be obtained with a single yarn. However, there are 8 types of yarns that are tightly bundled single yarns such as heated filament yarns and spun yarns, and yarns that are tightly bundled single yarns such as non-twisted multifilament yarns. Two different so-called convergence forms that combine yarns that are not
There are plied yarns made of threads and processed yarns with a core-sheath type.

It has been found that these conventional yarns have extremely unreasonable composite forms in order to effectively exhibit the characteristics of their constituent yarns.

<Problems to be Solved by the Invention> In other words, in the conventional yarn described above, the constituent threads are tightened by the combination twisting or twisting, so that gaps between the filaments and between the constituent threads are created. Because of this, there is a problem that good volume and warm taste cannot be obtained in the fabrics made and woven using the conventional yarn, and in particular,
In the case of core-sheath type processed yarns with an excessive difference in yarn length, there is a problem that the sheath yarns are likely to shift due to handling during the weaving and weaving process, resulting in nip-like defects, which is an important problem in practical terms. Contains many points.

The present invention is intended to solve the problems of conventional yarns as described above, and its purpose is to create a special intertwined yarn that can give good volume and warm color to the fabric obtained by knitting and weaving. is to provide.

<Means for Solving the Problems> Part 1 The present invention provides a substantially bundled yarn (hereinafter referred to as "bound yarn") and a substantially bundled yarn having a higher hot water shrinkage rate than the yarn. multifilament yarns (hereinafter referred to as "non-focused yarns") are intermittently entangled, and 60% or more of the total entanglements are in a form in which the focused yarns are interposed between the filaments of the non-focused yarns. The gist is a special interlaced yarn characterized by the following characteristics:

The configuration of the present invention will be explained in detail below.

FIG. 1 is a schematic side view of a special intertwined yarn (Y) according to the present invention, and the special intertwined yarn (Y) includes a bundled yarn (Yl),
Non-focused yarn (Yl) has a higher hot water shrinkage rate than the yarn (Yl).
The two threads (Yl) and (yz) are intermittently intertwined to form an intertwined part (8).

Moreover, between the interlaced parts, both threads (Yυ, (YZ)) form a non-entangled part (B) with low conjugation property.

2. In the present invention, the bundled yarn refers to single yarns that are twisted and fused without being opened by fluid treatment.

This refers to yarn that is relatively tightly bundled through entanglement, etc. On the other hand, non-tied yarn refers to untwisted or loosely twisted filament yarn that is created by opening single filaments through fluid treatment and entangling them. say something Also, both threads (Yl),
(YZ) is designed to make the yarn length difference as small as possible, but this improves the cohesiveness of the yarn (Y) as a whole.
This is to improve its morphological stability by eliminating displacement of the yarn layer due to handling. Further, as mentioned above, the special interlaced yarn (Y) of the present invention has a bundled yarn (Yl).
The hot water shrinkage rate of the non-focused yarn (YZ) is higher than that of In addition, the purpose is to emphasize the characteristics of the bundled yarn (Yl) on the fabric. That is, two special interlaced yarns of the present invention (Y)
When heat treating or dyeing a fabric using
In the non-entangled part (B) with low conjugation property of the special interlaced yarn (Y), which is a knitting yarn, the non-focused yarn (Y
Since Z) shrinks more than the bundled yarn (Yl), which has a small hot water shrinkage rate, the bundled yarn (Yl) becomes slack, and due to the slack, both yarns (Yl) and (Yz) Separate at the unentangled part (B) and form 1 as shown in Figure 2.
A large amount of inter-yarn voids (C) are formed between both yarns (Yl) and (YZ), which greatly enhances the polyurethane feel of the fabric.
) will also emphasize the characteristics on the fabric. Such an effect is caused by one double thread (Yl), (YZ)
The larger the difference in the convergence state of , ) becomes even more remarkable when it is 5% or more higher than the hot water shrinkage rate. However, in this case, the hot water shrinkage rate is JI
Measured by SL-1970 filament shrinkage test. Furthermore, due to the contraction of the two yarns (Yl) and (YZ), the strength of the interlacing at the interlacing portion (8) also becomes stronger.

As mentioned above, the intertwining form of the special intertwined yarn of the present invention is as follows:
between the filaments of non-focused threads (YZ).

The number of entanglements in which the bundled threads (Yl) intersect is
It is necessary to ensure that the number of entanglements is 60% or more of the total number of entanglements, including other forms of entanglement.
), (yz) will form a strong intertwined state that will not separate or move at the intertwined part (A) and shift their relative positions when they contract. By doing so, it is possible to promote the formation of the above-mentioned inter-yarn voids (C) in the non-entangled portion (B) and the action of the bundled yarn (Yl) to exhibit its characteristics on the fabric. This is because it becomes possible. In addition, as a form of entanglement other than the above, filaments of yarn (Yl) are interlaced with yarn (Yl).
), or when the yarn (YI) is a spun yarn, the fuzz of the spun yarn and the filaments of the yarn (Yl) are intertwined.

Furthermore, the special interlaced yarn (Y) of the present invention uses a multifilament yarn as its non-bound yarn (Yl), but the other bundled yarn (Yl) may include heated filament yarn, spun yarn, False twisted fused yarns, interlaced yarns and the like can be used, and it does not matter whether they are natural fibers or synthetic fibers.

FIG. 3 is a side view of an embodiment of the process for producing the special intertwined yarn (Y) of the present invention, in which the bundled yarn (Yl) is fed from the feed roller (1) and Feed the non-bundled yarn (y2) with a high hot water shrinkage rate to the roller (2).
After feeding the two yarns (yi) and (yz) together and sending them to an air injection nozzle (3) having interlacing performance, the nozzle (3) performs fluid treatment.

The special intertwined yarn (Y) of the present invention is used as a take-up roller (4).
The paper is taken up by the winding device (5) and rolled up by the winding device (5). in this case.

The feed speed of the feed roller (1) is set lower than the take-up speed so that the bundled yarn (Yl) is sent under tension to the air injection nozzle (3), and the feed speed of the feed roller (2) is set lower than the take-up speed. The speed is set higher than the take-up speed of the roller (4) so that the unfocused yarn (Yl) is fed into the air injection nozzle (3) in an overfeed state. The air injection nozzle is preferably an ordinary nozzle for entangling, but any type may be used as long as it has entangling performance.2 For example, a nozzle for forming a loop may be used. Then, the degree of tension (minus overfeed) of the focused yarn (Yl) during fluid treatment by the air injection nozzle (3), the degree of overfeed of the non-focused yarn (Yl), and the degree of tension (minus overfeed) of the focused yarn (Yl) during fluid treatment by the air injection nozzle (3). ) By adjusting the strength of the air pressure as appropriate, the number of entanglements in a form in which the focused threads (Y, ) are interposed between the filaments of the non-focused threads (Yl) can be determined.

The number of confounds can be 60% or more of the total number of confounds.

2. The method for measuring this entangled form is as follows.

First, the interlaced yarns are knitted into a tubular knitted fabric with a plain knitting structure under conditions that satisfy the following formula.

C=xW G; Number of knitting needles 7 inches D; Denier; 3 to 3.3.
C; Number of courses/inches W; Number of wales/inches x; 1.2
~1.3 Next, the knitted fabric was dyed at 100°C for 30 minutes without tension, and then unraveled to a yarn length of 1 m under a load of 0.02 g/d.
Observe and measure the confounding form with a magnifying glass, and calculate the total number of confounds T
(numbers/m) and the number K (numbers/m) of intertwining in the form in which a bundled yarn (Yl) is interposed between filaments of a non-focused yarn (Yl), and the ratio is calculated by -X100. Calculate. If the intertwined form is difficult to observe, dye one piece or bundle with different colors.

When a false twisted fused yarn is used as the bundled yarn (Yl), the special entanglement of the present invention can be manufactured by the steps shown in FIG. That is, the yarn to be fused and false-twisted is fed from a feed roller (6), a false-twisting heater (7) is set at a temperature at which the yarn is fused, and a false-twisting spindle (8) is used to give an appropriate number of false twists. ), fusion false twisting is performed at an appropriate overfeed rate, and this is sent as a focused yarn (Yl) to a feed roller (2) (delivery roller as a false twisting device). Yl) to the feed roller (1
), the two yarns (Yl) and (Yl) are combined and subjected to fluid treatment by an air injection nozzle (3) having interlacing performance to form the special entangled yarn (Y) of the present invention, which is transferred to a take-up roller (
The bundled yarn (yi) is taken up by step 4) and wound up by the winding device (5), but as in the process shown in FIG. In this state, the unfocused yarn (Y
The supply of l) is carried out in an overfeed state.

Furthermore, when using normal false twisted yarn as the non-focused yarn (Yl), the process shown in FIG. 4 is also used, but in this case, the yarn to be false twisted is passed through the feed roller. (6
), the false-twisted yarn is passed through the feed roller (2) as a non-focused yarn (Yl), and the other focused yarn (Yl) is passed through the feed roller (1). Supplied from. And same as above.

The non-bundled yarn (Yl) is fed in an overfeed state, and the bundled yarn (Yl) is fed in a tensioned state.

<Example> The present invention will be specifically explained below with reference to two examples.

Example 1 Using the process shown in FIG. 3, a 150 d/48 f cationic dyeable polyester multifilament heated yarn (500 T/M) with a hot water shrinkage rate of 8% was used as the bundled yarn (Y). is supplied from the feed roller (11), and 100 d/3 with a hot water shrinkage rate of 35% is supplied as a non-bundled yarn (Y2).
A 6f high shrinkage polyester multifilament yarn was used and fed from a feed roller (2) to produce an interlaced yarn. The surface speed of the feed roller (1) in this case was 297 m/min (overfeed rate 1%).

The surface speed of the feed roller (2) is 306 m/min (
overfeed rate 2%), the surface speed of the take-off roller (4) was 300 m/min, and the air pressure of the air injection nozzle (3) was 5 kg/cffl. In this way, the special interlaced yarn of the present invention as shown in FIG. 1 was obtained.

When a knitted fabric was knitted using this interlaced yarn and dyed, a fabric with excellent heat retention and warm color feeling was obtained. In addition, those subjected to different color dyeing or single dyeing exhibited a new scratched pattern. In addition, after dyeing a tubular knitted fabric created based on the method for measuring the intertwining form described above, the intertwining form of the threads was observed with a magnifying glass, and the number of entanglements per 1 m of yarn length was measured (measured). 5 times), the total number of entanglements was T = 53 pieces/m, of which there was a focused yarn (Yl) between the filaments of the non-focused yarn (Y2).
) was intervening in the number of forms = 38 pieces/m, so -X100 was 71.7%.

Example 2 Using the process shown in FIG. 4 and using three sets of focused yarns (Y,) and non-focused yarns (Y2) listed in Processing Levels 1 to 3 shown in Table 1, Fluid treatment was carried out under the conditions shown below to obtain two special entangled yarns of the present invention. In addition, the conditions for fusion false twisting in the case of processing size 3 are that the temperature of the false twisting heater (7) is 25%.
0℃, false twist number 2800T/M.

The overfeed rate was 6%.

Weaving and weaving using the special interlaced yarn of the present invention of processed yarn 1 and processed fish 2 using non-focused yarn (Y2) that undergoes normal false twisting between feed roller (6) and feed roller (2) When the fabric was dyed and finished, it was wiped.

A product with good taste was obtained. Particularly in the case of processing number 2, the texture was similar to that of mercerized cotton. Also, feed roller (
When the fabric knitted and woven using the special interlaced yarn of the present invention in the processing stage 3 using the bundled yarn (Yl) that was falsely twisted and fused between the feed roller (2) and the feed roller (2) was dyed and finished, the false twisted The fused yarn floated to the surface of the fabric, giving it a crisp texture and a new appearance.

<Effects of the Invention> Since the special entangled yarn according to the present invention has the above-mentioned configuration, yarns having different convergence properties and hot water shrinkage rates are entangled, and the form of the entanglement is special. Due to the synergistic effect of the difference in hot water shrinkage rate during the dyeing process etc. and the special entangled form, the resulting difference in yarn length forms a large number of inter-row voids. The fabric is
It has a remarkable sense of volume, a sense of warm color, and a surface structure rich in variation. In addition, in the special interlaced yarn of the present invention, there is almost no difference in yarn length between the constituent yarns at the yarn stage, and there are many strong entanglements that connect the constituent yarns intermittently.
The special interlaced yarn as a whole has extremely good bundling properties, so the yarn layers do not shift even when handled during the weaving and weaving process, and therefore have excellent morphological stability. Since it has good unwinding properties, it maintains good operability.

Furthermore, the texture and appearance of the special interlaced yarn of the present invention can be set as desired by changing the combination of the material fibers of both yarns, and by changing its hot water shrinkage rate and discoloration properties. It is a yarn of extremely high versatility and practical value.
