Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a composite thread for embroidery lace. More specifically, the present invention relates to a composite 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 the expansion and contraction of the fabric of the embroidery lace.
[0002]
[Prior 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 be stretchable in order to improve fit with the human body. Therefore, in conventional embroidery laces, for example, a stretch warp knitted fabric with a structure such as a power net is used as the fabric, and as the embroidery thread, the stretch is suppressed, and the stretch is controlled by the subsequent dyeing process. A developing yarn is used.
[0003]
In the embroidery lace, the pattern is formed by sewing the lace fabric with two embroidery threads as the front and back threads. When the embroidery thread has elasticity, This is because a loop by lock stitching cannot be formed. Therefore, in the past, the elasticity has been suppressed to such an extent that it can be embraced without problems as described above, but after the lace fabric has been embroidered and formed into a pattern, the suppression is released by processing during dyeing and arranging processing. A yarn capable of expressing stretchability (hereinafter referred to as latent stretch yarn) is used.
As an example of this kind of latent elastic yarn, Japanese Patent Laid-Open No. 2-14061 discloses a yarn in which a stretched elastic yarn in a relaxed state is drawn without being drafted on a water-soluble fiber yarn, and a water-insoluble fiber yarn is spirally wound thereon. Is disclosed. In the case of this latent stretch yarn, if the pattern is formed on the lace fabric and then treated with warm water, the water-soluble fiber yarn dissolves so that the embroidery yarn forming the pattern can expand and contract in accordance with the expansion and contraction of the fabric. become.
[0004]
[Problems to be solved by the invention]
The latent stretch yarn of the above type is excellent in that it gives stretchability corresponding to the lace fabric to the embroidery lace pattern, but it causes a problem that yarn breakage frequently occurs during the embroidery process. That is, this type of latent stretch yarn has a large number of pills (loop-like protrusions) on its surface. Since this seed yarn is aligned with the water-soluble fiber yarn without drafting the stretchable elastic yarn as described above, there should be no pills in theory, but there is no tension with any device. It is impossible to wind the yarn in the state, and in reality, a slight tension is applied to the elastic elastic yarn, and there is elongation due to the tension and shrinkage due to recovery of the elongation. Will occur. Therefore, the latent elastic yarn accommodated in the shuttle during the embroidery process has a problem that the pill is likely to break when the pill is caught in the shuttle when pulled out from the shuttle.
[0005]
The present invention solves the problems of conventional stretch yarns for embroidery lace that are known in the art, so that there are no operational defects such as thread breakage during embroidery, and the pattern of embroidery lace by processing after embroidery. An object of the present invention is to provide an embroidery thread capable of giving stretchability corresponding to a lace fabric to a portion.
[0006]
[Means for Solving the Problems]
The above-mentioned object of the present invention is to insert a wedge yarn consisting of a non-stretchable yarn that can be dissolved or decomposed by a solvent containing water or heat, along the longitudinal direction of the wedge yarn. This is achieved by a composite embroidery thread for embroidery laces, characterized in that it is composed of an insertion thread made of at least one stretchable thread.
The knitting yarn referred to here is a knitting process in which a yarn portion continuous with the yarn portion constituting the preceding stitch is bent and the new stitch loop is passed through the preceding stitch loop to form a new stitch loop. It is a knitting yarn obtained by repeating continuously.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Examples of the non-stretchable yarn include water-soluble vinylon (polyvinyl alcohol yarn) that can be easily dissolved in warm water, yarn that can be dissolved in a solvent that dissolves water, such as diacetate yarn that can be dissolved in acetone, and heat. In some cases, any yarn may be used as long as it is a yarn that can be decomposed by light and has a strength sufficient to withstand the tension when squeezing.
As the stretchable yarn, spandex yarn and covering yarn using spandex yarn as a core yarn are generally used. However, depending on the use of the embroidery lace, a strong twisted yarn or a textured yarn can be used as the elastic yarn.
[0008]
The non-stretchable yarn and the stretchable yarn are supplied to the needles of the warp knitting machine through different yarn guides, and the yarn guide for the non-stretchable yarn is reciprocated in the comb-knitting yarn forming mode to generate the comb-knitting yarn. The composite yarn of the present invention is obtained by knitting and simultaneously inserting the elastic yarn into the non-elastic yarn wedge yarn by reciprocating the yarn guide for the elastic yarn in the insertion yarn forming mode. It is done.
At that time, two or more non-stretchable yarns and stretchable yarns may be used for knitting to form a yarn. The number of yarns of the embroidery lace together with the type and thickness of the elastic yarn used. What is necessary is just to determine arbitrarily based on the effect on a design. Non-stretchable yarns that are dissolved or decomposed after tanning should be used in a small amount within a range that can withstand the tension when squeezing and that the stretchable yarn can be kept in the knitting yarn. preferable.
[0009]
The structure of the composite thread of the present invention will be described with reference to the accompanying drawings showing an example of the composite thread of the present invention. FIG. 1 (A) shows a composite knitting yarn 1 in which an insertion yarn 2 is inserted in a straight stitch knitting yarn 3 with a straight hook, and FIG. 2 (A) shows a knitting yarn 3 similar to FIG. 1 (A). Fig. 3A shows a composite knitting yarn 1a having an opening and an insertion yarn 2a inserted in reverse, and Fig. 3 (A) shows the insertion yarn 12 inserted in a closed knitting yarn 13 by hooking. A composite thread 11 is shown. 1A, FIG. 2A and FIG. 3A are all yarns showing how an insertion yarn made of a stretchable yarn is knitted on a wedge knitting yarn made of a non-stretchable yarn. It is a structural diagram, and in an actual composite knitting yarn after knitting, the elastic yarn becomes a straight line, and accordingly, the shape of the loop of the knitted yarn is different from the shape shown in the drawing. Whether the knitting yarn is knitted with open or closed stitches, and whether the insertion yarn is inserted with the front or back is arbitrary depending on the application of the composite yarn, the type of yarn used, or the knitting conditions It only has to be selected.
1A, FIG. 2A, and FIG. 3A, the wedge knitting yarns 3, 13 are in the axial direction of the composite knitting yarns 1, 1a, 11 indicated by 3a, 13a. A thread portion extending through the loop of the knitting yarns 3 and 13 while the insertion yarns 2, 2a and 12 pass through the loops of the knitting yarns 3 and 13; 1a, 11 extends in the axial direction. As a result, the insertion yarns 2, 2a, 12 of the elastic yarn are encased in the knitting yarns 3, 13 and entangled like a core yarn. For this purpose, the loops of the non-stretchable yarns of the cut yarns 3, 13 tighten the stretchable yarns arranged as the insertion yarns 2, 2a, 12. The strength and interval of the tightening and the elongation of the obtained composite yarns 1, 1 a, 11 are adjusted by adjusting the amount of non-stretch yarn sent for the wedge knitting yarns 3, 13 at the time of manufacture. It can be freely changed according to the use of 1, 1a, 11. FIG. 1B, FIG. 2B and FIG. 3B are knitting structure diagrams of the corresponding composite thread.
[0010]
In the composite thread of the present application, since the non-stretchable yarn is entangled with the stretchable yarn by the loop of the knitting yarn, the pill does not occur like the above-described conventional latent stretch yarn, and the surface is relatively smooth. Become a thread. Therefore, the thread does not get caught in the eyes of the shuttle when squeezing, and therefore, thread breakage is very rare when squeezing. In addition, the passage of the eyes of the shuttle is smooth, so that there is no unevenness of tension and a clear pattern can be formed.
[0011]
Since a warp knitting machine has several hundred knitting needles, when producing a composite yarn of the present invention using a conventional warp knitting machine, a large number of knitting stations are provided at intervals. A large number of yarns obtained in (1) above may be individually wound, or they may be wound together (provided with an interval or partition) on a conventional warp knitted fabric winding bobbin, and then separated into individual bobbins. . 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.
[0012]
【Example】
Examples of the composite embroidery thread for embroidery lace according to the present invention will be described below.
Example 1
Supply a water-soluble vinylon yarn 56d to the front side of a two-ply Russell warp knitting machine, and knitting a spear knitting. At the same time, insert a nylon multifilament 70d / 2 strong twisted yarn (upper twist 4000 T / M) into the back side. As a composite yarn. The degree of yarn of the above-mentioned knitting yarn was 50 per 1 cm (2.54 cm).
On the other hand, a power net with a basis weight of 100 g / m ² was knitted using nylon multifilament 30d and polyurethane 70d to form an embroidery lace fabric, and a floral pattern was engraved on the lace fabric with the composite yarn. There was no breakage of the thread during the process. The obtained lace fabric was scoured to give a finishing agent 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 composite yarn of the present invention as an embroidery yarn is the same as the elongation of the lace fabric of the power net structure. It was almost the same 2 to 2.5 times.
[0013]
Comparative Example 1
A power net similar to the embodiment is used by using a conventionally known latent stretch yarn in which a water-soluble vinylon yarn 56d is aligned with a relaxed spandex yarn 40d and a nylon multifilament yarn 30d is wound thereon as an embroidery yarn. The embroidery lace fabric was manufactured. In this case, when the raw lace fabric was manufactured, cutting due to clogging of the latent elastic yarn shuttle occurred frequently, and it was not in a state where mass production was possible. The obtained lace fabric was scoured in the same manner as in Example to dissolve the water-soluble vinylon yarn to obtain an embroidery lace.
[0014]
Comparative Example 2
The water-soluble vinylon yarn 56d is aligned with the relaxed spandex 40d, and a conventionally known latent stretch yarn in which a nylon textured yarn 70d and a water-soluble vinylon yarn 56d are wound together is used as an embroidery yarn. An embroidery lace fabric was produced in the same manner as in the examples, and this lace fabric was scoured in the same manner as in the examples to dissolve the water-soluble vinylon yarn to obtain an embroidery lace. In this case, as in Comparative Example 1, the shuttle fabric is frequently clogged during the production of the lace fabric, and the so-called fluffy yarn in which the embroidery lace does not become jammed by removing the water-soluble vinylon in the resulting embroidery lace. Thus, the appearance of the resulting embroidery lease was extremely bad.
[0015]
Example 2
A 40 k of water-soluble vinylon yarn was supplied to the front side of a two-ply Russell warp knitting machine to knitting a knitting. As a yarn to be inserted on the back side, a composite yarn was obtained using a spandex yarn 70d and a covering yarn using two nylon multifilaments 20d.
Using the obtained composite yarn, an embroidery lace base fabric was prepared in the same manner as in Example 1, and scoured to obtain an embroidery lace. When the composite yarn of Example 2 was used, an embroidery lace having excellent appearance with no occurrence of yarn breakage during embroidery was obtained as in Example 1.
[0016]
【The invention's effect】
The composite embroidery thread for the embroidery lace of the present invention is composed of a non-stretchable yarn and a stretchable yarn that can be removed during post-processing after lace production and entangled with a pair of knitting yarns, so that the surface is relatively As a result, the yarn became smooth, and the occurrence of thread breakage at the time of sewing was extremely small. As a result, the embroidery lace having the same stretchability as the lace fabric could be mass-produced.
