DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite embroidery thread for embroidery lace. More specifically, the present invention relates to a composite embroidery thread used for forming a pattern portion of an embroidery lace having elasticity and capable of forming a pattern portion that can expand and contract in accordance with expansion and contraction of the fabric of the embroidery lace.

[0002]

2. Description of the Related Art Embroidery laces are widely used in women's underwear such as bras and lingerie. The embroidery lace used for women's underwear is required to have elasticity in order to improve the fit with the human body. Therefore, in the conventional embroidery lace, a stretchable warp knitted fabric with a structure such as a power net is used as the fabric, and the stretchability is suppressed as the embroidery thread during embroidery processing. An emerging thread is used.

[0003] In the embroidery lace, a pattern is formed by performing a lockstitch on lace fabric using two embroidery threads as a front thread and a back thread.
At that time, if the embroidery thread has elasticity, it is not possible to form a loop by lockstitch. Therefore, conventionally, the elasticity is suppressed to the extent that embroidery can be performed without hindrance as described above, but after the lace fabric is formed into a pattern and formed into a pattern, the above suppression is released by processing at the time of dyeing and rearranging processing to expand and contract. A yarn capable of exhibiting properties (hereinafter referred to as a latently stretchable yarn) is used. As an example of this type of latent stretch yarn, a relaxed stretch elastic yarn is aligned with a water-soluble fiber yarn without drafting, and a water-insoluble fiber yarn is spirally wound thereon.
No. 1 discloses this. In the case of this latently stretchable yarn, if the lace fabric is embossed to form a pattern and then treated with warm water, the water-soluble fiber yarn dissolves and the embroidery yarn forming the pattern can expand and contract in accordance with the expansion and contraction of the fabric. become.

[0004]

The latent stretch yarns of the above type are excellent in that they give the embroidery lace pattern stretchability corresponding to the lace fabric.
There is a problem that yarn breakage frequently occurs during embroidery processing. That is, this type of latent stretch yarn has a large number of pills (loop-like projections) on its surface. Since this kind of yarn is adjusted to the water-soluble fiber yarn without drafting the stretch elastic yarn as described above, there should be no pill in theory, but there is no tension even if any device is used It is impossible to wind the yarn in this state, and in reality, a slight tension is applied to the stretchable elastic yarn, there is elongation due to the tension, and there is shrinkage due to the recovery of the elongation. Will occur. Therefore, there is a problem that the latent stretchable yarn accommodated in the shuttle during the embroidery process is liable to be broken due to the pill getting caught in the eyes of the shuttle when pulled out from the shuttle.

[0005] The present invention solves the problems of the conventionally known latently stretchable yarn for embroidery lace, eliminates operational defects such as yarn breakage during embroidery processing, and provides processing after embroidery processing. It is an object of the present invention to provide an embroidery thread that can give the embroidery lace pattern a stretchability corresponding to the lace fabric.

[0006]

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is as follows.
A non-stretchable yarn and a stretchable yarn which can be dissolved or decomposed by a solvent containing water or heat;
This is achieved by a composite embroidery thread for embroidery lace, wherein the non-stretchable thread and the at least one stretchable thread are combined in a warp knitting structure.

Examples of the non-stretchable yarn include a water-soluble vinylon (polyvinyl alcohol yarn) that can be easily dissolved in warm water, a diacetate yarn that can be dissolved in acetone, and a yarn that can be dissolved in water or a solvent. Any yarn may be used as long as it can be decomposed by heat or, in some cases, light, and has a strength enough to withstand the tension at the time of embossing. As the elastic yarn, a spandex yarn and a covering yarn having a spandex yarn as a core yarn are generally used. However, depending on the application of the embroidery lace, a strong twist yarn or a textured yarn can be used as the elastic yarn.

The non-stretchable yarn and the stretchable yarn are usually 1
One by one, it is supplied to the adjacent needle of the needle bed of the warp knitting machine, entangled in the warp knitting structure and combined to form one yarn. At that time, the yarn may be formed by knitting by using two or more non-stretchable yarns and two or more stretchable yarns, and the design of the embroidery lace pattern along with the type and thickness of the stretchable yarn to be used. It may be arbitrarily determined based on the effect. Non-stretch yarn that is dissolved or decomposed at a later date should be used in a small amount within a range that can withstand the tension during embroidery processing and that can keep the stretch yarn in a warp knitting structure. preferable.

The term "composite in the warp knitting structure" means that the non-stretchable yarn and the stretchable yarn are entangled with each other in the warp knitting structure. For example, as shown in FIG. 1, the composite embroidery thread 1 of the present invention is composed of a stretchable thread 2 and a non-stretchable thread 3, and the stretchable thread 2 inserted and arranged like a core thread is non-stretchable in a hollow knitting. It is preferable that it is configured so as to be wrapped with the sex yarn 3. With this configuration, the loop of the non-stretchable yarn 3 clamps the stretchable yarn 2, and the strength and interval of the tightening and the elongation of the obtained composite embroidery thread 1 depend on the non-stretchability during the production of the embroidery thread. By adjusting the delivery amount of the yarn 3, it can be freely changed according to the use of the obtained composite embroidery yarn 1.
Since the composite embroidery thread of the present application is such that the non-stretchable thread is entangled with the stretchable thread by the warp knitting loop, no pill is generated unlike the above-mentioned conventional latent stretchable thread, and the surface is relatively smooth. It becomes a thread. Therefore, the thread is not clogged with the eyes of the shuttle during the embroidery process, and therefore, the occurrence of thread breakage during the embroidery process is extremely small. In addition, since the eyes of the shuttle pass smoothly, clear patterns can be formed without unevenness in tension.

[0010] Since the warp knitting machine has hundreds of knitting needles, when the conventional warp knitting machine is used to manufacture the composite embroidery thread of the present invention, a number of knitting stations are provided at intervals.
A large number of yarns obtained for each knitting station are individually wound, or collectively wound on a conventional warp knitting fabric winding bobbin (at intervals or partitions), and then sorted into individual bobbins. You may wind it up. Of course, a dedicated yarn manufacturing machine in which a unique yarn winding mechanism is connected to the knitting mechanism of a conventional warp knitting machine may be used.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the composite embroidery thread for embroidery lace of the present invention will be described below. Example 1 A water-soluble vinylon yarn 28d was supplied to the front side of a two-reed Russell warp knitting machine to knit a knitted fabric, and at the same time, a strongly twisted nylon multifilament 70d / 2 (twisted 4000).
T / M) was supplied to the back side as an insertion yarn to form a composite yarn. The length of the thread of the hollow knitting is 1 inch (2.54 cm)
50 per hit. Nylon multifilament 3
100 g / m ² using 0d and polyurethane 70d
Was formed into a lace fabric for an embroidery lace, and a floral pattern was formed on the lace fabric with the composite yarn. There was no breakage of the embroidery thread during the embroidery process. The obtained lace raw fabric was scoured and a finishing agent was applied to obtain an embroidery lace. The water-soluble vinylon yarn in the composite yarn is completely dissolved, and as a result, the elongation of the pattern portion of the embroidery lace using the conjugate yarn of the present invention as an embroidery yarn is the same as the elongation of the lace fabric itself having a power net structure. It was about the same 2 to 2.5 times.

As a comparative example, a water-soluble vinylon yarn 28d was aligned with a relaxed spandex yarn 70d, and a conventionally known latent stretch yarn obtained by winding a nylon multifilament yarn 30d thereon was used as an embroidery yarn. Embroidered lace blanks were manufactured on the same power net. In this case, when producing the original lace fabric, the potential elastic yarn was frequently cut due to clogging of the shuttle, and it was not in a state where mass production was possible at all. The obtained lace raw fabric was scoured in the same manner as in the example, and the water-soluble vinylon yarn was dissolved to obtain an embroidery lace.

Example 2 A water-soluble vinylon yarn 40d was supplied to the front side of a two-reed Russell warp knitting machine to knit a hollow knitting. As the yarn to be inserted into the back side, a composite yarn was obtained using two spanning yarns 70d, nylon multifilament 20d and two covering yarns. Using the obtained composite yarn, an embroidery lace base fabric was prepared in the same manner as in Example 1 and scoured and finished to obtain an embroidery lace. Also in the case of using the composite yarn of Example 2, as in Example 1, there was no occurrence of yarn breakage during embroidery lace processing, and an embroidery lace having an excellent appearance was obtained.

[0014]

According to the composite embroidery thread for embroidery lace of the present invention, a non-stretchable thread and a stretchable thread which can be removed during post-processing after lace production are entangled in a warp knitting structure and are compounded. , The surface becomes relatively smooth yarn, so the occurrence of yarn breakage during embroidery processing is extremely small, and as a result, it is possible to mass-produce embroidery lace with the same stretchability as the lace fabric in the pattern part Was.
