Description

[Detailed Description of the Invention] The present invention provides a novel and unprecedented design sewing thread that has a design effect and also has a suitable sewing effect when used as a sewing thread.

That is, conventionally designed yarns in which a metal-deposited film is wound around a suitable core yarn have been widely used as so-called lame yarns. However, the core thread of such lame thread is not strong enough to withstand sewing, and since ordinary lame thread has a vapor-deposited film wrapped around it without any gaps, it can be applied to sewing machines as is. When this occurs, the surface may peel off or shift due to friction with a needle, etc., making it unusable. In addition, such lame threads have little variation in design because they are wound with only a limited single color of vapor-deposited metal, such as gold for gold or silver for silver, without gaps.

The present invention provides a novel sewing thread that has not been previously seen in this respect, and is characterized by the fact that a plurality of threads having a first twist are combined, and the sewing thread is 300 to 1200 T/2 in the opposite direction to the first twist. It is characterized in that a colored thread consisting of M ply-twist is used as a core thread, and a narrow metal-deposited film cut into slits is wound spirally around the core thread so that the core thread is exposed. be. This will be explained below using an example.

<Example 1> Three 60 count polyester spun yarns with a first twist of 1200T/M in the S direction are aligned and plied, and after adding a final twist of 900T/M in the Z direction, this is made into blue. It was dyed to form a core thread. On the other hand, a #50 (12μ) 80 cut (1/80 size) lame thread made of a polyester film with aluminum vapor-deposited was prepared as a metal-deposited thread to be wrapped around the thread, and was governed using a circular twisting machine under the following conditions.

Spindle rotation: 8000 rpm Take-up speed: 7-12 m/min Using a flyer The sewing thread obtained in this way is a new thread that is continuously wound in a spiral shape so that the core thread 2 is exposed to a width approximately the same as that of the cover thread 1, as shown in Figure 1. When this is used as the upper thread of a lockstitch sewing machine, it shows excellent sewing performance without thread breakage. Furthermore, the use of a core thread with a different color tone from the metallic color of the glitter thread creates a two-color color change, which has a design effect of presenting an appearance rich in elegance never seen before.

<Example 2> Three 60 denier polyester filament yarns with a first twist of 1100 T/M in the S direction were pulled together and plied together, a final twist of 700 T/M was added in the Z direction, and this was dyed red. The core yarn was constructed using the following methods. On the other hand, a #50 (12μ) 80 cut (1/80 size) lame thread made of polyester film deposited with silver was prepared as a metal-deposited thread to be wrapped around this, and this was covered using a circular twisting machine under the following conditions.

Spindle rotation: 12000r.pm Take-up speed: 10-18m/min Use of fryer The sewing thread thus obtained was wound spirally and continuously so that the core thread 2 was exposed to the cover thread 1 in its width. It became a thread.

When this was used as an embroidery thread, it could be used as an excellent design thread without any trouble.

In addition, the thread used as the core thread in this invention is natural,
Any synthetic fiber may be used, such as mono, multi-fiber, spun yarn, etc.

Also, in the direction of untwisting the ply twist, the ply twist is applied in the Z direction in a range of 60 to 100% of the ply twist number in order to obtain a ply twist of 300 to 1200 T/M. Therefore, if this is less than 60%, the strength will decrease due to poor conjugation, and the strength will decrease to 100%.
This is because if the twist is too strong, snarls will occur and it will not be possible to sew properly. Incidentally, the core yarn is preferably a spun yarn as in Example 1,
Furthermore, when the cutting elongation is set to 13 to 17%, the sewability is further improved.

Next, as lame threads to cover this, foil sheets and iris sheets that are common gold and silver thread materials, that is, synthetic resin films with a metal layer provided by vacuum deposition, sputtering, etc., or gold,
It is possible to use a material to which silver or iris foil is pasted, etc., which is cut into an arbitrary width using a slitter. Furthermore, when covering, yarn feeding speed,
By changing conditions such as tension, the exposed width of the core yarn can be changed arbitrarily.

As described above, the present invention has an excellent effect as a sewing thread that has not been seen before, and is a thread rich in elegance that can be applied to a wide range of uses as a needle thread, swing thread, etc. of a sewing machine.
