Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides that the elastic thread used in sewing thread for embroidery is held in the sewing thread without being drafted substantially, and is highly elastic and flat. The present invention relates to a method for producing stretchable embroidery lace with excellent properties.

(Prior art) Generally, embroidery lace is made by using an embroidery machine to embroider a base fabric using front and back threads, but when the base fabric has elasticity, the base fabric stretches and the embroidery is difficult. Because it is difficult to do this accurately, usually a fabric made of paper or water-soluble fibers is polymerized with or without an adhesive as a base fabric, and then an embroidery machine is used to embroidery the paper or water-soluble fiber. A method of washing and removing a water-soluble fiber fabric with water, or making a base fabric using a combination of a stretchable elastic filament and a non-stretchable water-soluble fiber thread, and then applying stitching to this using a thread made of insoluble fibers. After that, the fibers are immersed in an aqueous solvent to dissolve and remove the water-soluble fibers.

However, with these methods, even though the base fabric has elasticity, the threads used for embroidery are non-stretchable, so when stitching,
When the lace fabric is stretched, some parts of the pattern do not stretch, resulting in a decrease in commercial value.

Therefore, as a method to overcome this drawback, a method was proposed in Japanese Patent Application Laid-Open No. 2003-101002 in which the elasticity of a thread with stretchability was temporarily killed using water-soluble fiber thread, and used as a stitching thread.
This was proposed in Publication No. 54-106672, etc.

According to the description in the same publication, this method uses a yarn having rubber-like elasticity as a core yarn, a yarn made of a water-soluble polymer as an inner cover yarn, a yarn made of a water-insoluble fiber yarn as an outer cover yarn, Draft 2~
3. Create a thread that has no elasticity by covering it at a rotation speed of about 8000 times/min. After embroidering this thread using an embroidery machine as the front and back threads, embroidery is carried out using a water-based solution. In this method, the water-soluble polymer fibers are dissolved and removed by immersion in the water.

(Problem to be solved by the invention) However, in the embroidery lace made by this method, the draft of the thread having rubber-like elasticity is 2 to 3 when covering the thread, and it is stretched, so water-soluble fibers After the threads are removed, it returns to its original state and undergoes significant shrinkage, and as stated in the same bulletin, the embroidery cloth has shrunk by approximately 45% in both the weave and the weave, and is extremely uneven and unsatisfactory in terms of aesthetics. It had its drawbacks.

The present invention has focused on such drawbacks, and the present invention has developed a yarn with stretch elasticity that is made into its original size and does not substantially shrink even after the removal of the water-soluble fiber yarn, and has a shape that is approximately close to the original size after being embroidered, with no unevenness. The object of the present invention is to obtain a stretchable embroidery lace with excellent flatness, with particular attention paid to the improvement of the draft in embroidery threads, and the purpose of the present invention is to solve the problem.

(Means for Solving the Problems) That is, a feature of the present invention is to finally obtain a sewing thread for stitching in which the elastic thread is coated with a water-insoluble fiber thread. Of course, a water-insoluble fiber yarn is used in combination with the stretchable yarn, and a water-soluble fiber yarn is also used in combination so that the stretchable yarn has a draft of 1 and is not substantially stretched. A thread for embroidery is made, and this thread is used as a sewing thread to embroidery the surface of the base fabric made of stretchable fabric.
For example, by temporarily fixing the elasticity of a stretchable base fabric with a fabric made of water-soluble fiber threads, and then applying stitching to both fabrics, the water-soluble fiber threads used are dissolved and removed. Stitching is applied to the stretchable base fabric surface.

Here, the stretchable and elastic threads used in the embroidery thread include polyurethane elastic threads, rubber threads, etc., while the water-insoluble fiber threads include synthetic fibers such as nylon and polyester, rayon, and cotton. Various types of fibers can be used.

When forming the covered thread,
For example, a thread made of a water-soluble fiber thread is used as a yarn having elasticity, and is made into a gathered thread and covered with the water-insoluble fiber thread, or the thread having elasticity is covered with a water-insoluble fiber thread. is covered with water-soluble fiber threads, and the water-soluble fibers are further entwined with each other.

In this case, threads made of polyvinyl alcohol, poly-β-alanine, alginate, etc. can be used as the water-soluble fibers. Furthermore, covering the stretchable elastic yarn can be obtained by single or double covering with the water-insoluble fiber, but the stretching elastic yarn is not substantially stretched during covering. The most important point in the present invention is to supply the material in the draft 1 state.

That is, when covering the water-insoluble fiber yarn with the above-mentioned covering, a covering machine with a hollow spindle is usually used so that the yarn having elasticity is hardly stretched from the actively driven feeder. This is done by feeding yarn and covering it with water-insoluble fiber yarn, but the coating takes into account the ease of stitching, the number of twists, the thickness of the covered yarn, whether it is processed yarn, whether it is single or double, etc. is selected.

In addition, in order to feed the stretchable elastic yarn with almost no stretching and substantially at draft 1, the surface speed of the roll that sends out the stretchable elastic yarn and the surface speed of the roll that takes up the yarn after coating are determined. This is achieved by setting the ratio of

On the other hand, the base fabric for embroidery is a stretchable fabric, which may be either woven or knitted, but the preferred fabric is spandex core spun yarn, which is stretchable in warp and weft. These include woven fabrics, warp knitted fabrics made by combining polyurethane elastic yarns with other fiber yarns, and knitted fabrics such as circular knitted fabrics.

Further, knitted fabrics such as so-called jersey and tricots having greater elasticity in only one direction can also be used.

When embroidering, this stretchable base fabric is temporarily fixed in its stretchability, but this is done by attaching a woven or knitted fabric made of water-soluble fibers such as polyvinyl alcohol to a stretchable fabric. This can be done with or without a polymerized adhesive.

Thus, the above-mentioned covered thread was used as a sewing thread on a base fabric made of an elastic fabric whose elasticity was temporarily fixed as described above, and embroidery was performed using an embroidery machine or the like as usual, and then The lace of the present invention can be produced by immersing the lace in a water-based solvent and dissolving and removing the water-soluble fiber threads contained in the lace.
The sewing thread does not shrink, and therefore a stretchable embroidered lace with a shape close to the original embroidered size and excellent flatness with few irregularities can be obtained.

Other laces having the same effect can also be obtained by using a fabric made of water-soluble fiber yarn as the base fabric.

(Function) In the above-mentioned embroidery lace, the stretchable elastic thread is not drafted and is included in the embroidery sewing thread with draft 1, and therefore does not shrink in the weft and weft directions. The lace remains in its original size, and when stretched, it exhibits the required elasticity and elasticity compared to its original size, and since it is initially started from its original size, unevenness and wrinkles due to shrinkage will not occur on the lace surface. It is possible to produce a lace with good flatness and no wrinkles.

(Example) Hereinafter, an example of the manufacturing method of the present invention will be described further based on the accompanying drawings.

The figure shows one example of lace obtained by the method of the present invention, in which 1 is a base fabric made of a stretchable fabric, and is a knitted or woven fabric that has stretchability in two directions or has greater stretchability in one direction. During the embroidery process, the fabric made of water-soluble fiber threads is polymerized and its elasticity is temporarily stopped.
After the stitching, the water-soluble fiber threads are dissolved and removed by an aqueous solvent, resulting in only a stretchable fabric.

On the other hand, reference numeral 2 designates an embroidery pattern applied to one surface of the base fabric, which is formed by a thread having elasticity coated with a water-insoluble fiber thread. As mentioned above, this coated sewing thread for embroidery uses both a stretchable and elastic thread and a water-soluble fiber thread, but the stretchable and elastic thread is fed to the water-insoluble fiber thread at a draft ratio of 1. The elastic yarn is coated with a water-insoluble fiber yarn, and the stretchable elastic yarn maintains its actual size by dissolving and removing the water-soluble fiber yarn.

That is, in general, threads having elasticity are often covered with water-insoluble fiber threads in a stretched state.
Therefore, when the expansion is released and the material is contracted, unevenness is likely to occur, but in the present invention, since the draft 1 is in the actual size state, no unevenness is observed at all.

Thus, the stretchable elastic thread with the above-mentioned actual size is used in combination with the water-soluble fiber thread, and stitching is performed on the stretchable fabric surface according to the usual method as a stitching thread, and then the contained water-soluble fiber thread is sewn. The lace of the present invention is obtained by dissolving and removing.

In the lace of the present invention obtained in this manner, the stretchable elastic yarn contained therein is in the original size state, so if it is stretched, it will start stretching from the original size state. This is because the conventional embroidery on a stretchable base fabric is covered with stretchable elastic thread as the embroidery thread in a stretched state, so it is smooth in the stretched state, but in the contracted state when the stretch is unwound. This is in contrast to the generation of wrinkles on the surface of the base fabric, which is an advantage of the present invention.

The above-mentioned embroidery lace is made by using a normal embroidery machine, but it can also be made by other embroidery machines or lace machines.

In this way, the above-mentioned lace obtained can be used for various purposes,
Particularly in recent years, lace is often used in luxury items such as women's underwear, foundations, and swimwear.

(Effects of the Invention) As described above, the present invention has a draft 1 and uses a stretchable elastic thread as a core thread without being substantially stretched, and a thread coated with a water-insoluble fiber thread is used as a sewing thread for sewing stretchable fabric. The combination of the stretchable base fabric and the sewing thread with stretchable elasticity makes it possible to obtain a lace fabric with good stretchability over the entire area. Since the stretchable elastic thread of the embroidery thread is covered with a draft 1 without being stretched, it does not shrink at all after being embroidered, compared to conventional sewing threads that are covered in a stretched state. The lace surface is finished in a shape close to the original size without any wrinkles or unevenness caused by shrinkage, which not only improves the product value compared to laces that use conventional stretchable elastic threads or sewing threads, but also improves the product value when deciding on the design. This method is also extremely effective, and is expected to be used more widely in the future as a novel method for producing stretchable lace.
