特開昭５７−１６１１３６号公報により提案されている
。Polyester sewing thread is often used as sewing thread for industrial use as opposed to home use, because of its excellent sewing ability, high strength, and excellent dyeing toughness. but,
Polyester sewing thread also has the problem of easily skipping stitches when used in higher speed sewing machines, especially multi-needle sewing machines such as flat seamers. In order to solve this problem, it has been proposed in JP-A-57-161136 to use a polyester fabric with low elongation.

目とびを防止することが特開昭５４−４６９９７号公報
により提案されている。However, this measure has a limit in reducing the elongation of polyester fabric, and is not sufficient to actually solve the skipped stitch problem. Further, it has been proposed in Japanese Patent Application Laid-Open No. 46997/1987 to lower the elongation of polyester sewing thread by subjecting the polyester spun thread to tension heat setting to prevent skipped stitches.

テルミシン糸の製造コストをはっきり上昇させる。However, this measure has a limit in reducing the elongation of polyester sewing thread, and it is difficult to say that it can actually prevent skipped stitches sufficiently, and the tension heat setting of spun thread requires equipment for that purpose. This clearly increases the manufacturing cost of polyester sewing thread compared to lowering the elongation of polyester fabric.

The purpose of this invention is to provide polyester sewing thread that can be manufactured using

ある。The present invention is a product in which spun yarn of polyester sewing thread is mixed with a small amount of polyester fabric that heat softens or melts at the high-pressure dyeing temperature of polyester fabric. This was done based on the knowledge that if polyester sewing thread is made to have high bending rigidity by heat softening or melting, stitch skipping will not occur even when used in various high-speed sewing machines, and it is better than polyester fabric and polyester fabric. It consists of a blended yarn with a copolymerized polyester fabric having a blending ratio of 0.2 to 10.0% by weight with a low melting point, and the copolymerized polyester fabric is deformed by heat softening or melting, and has a bending rigidity of 10.Of -cm2/ae
The sewing thread is characterized in that it has a diameter of X 10-' or more.

A preferred example is a polymer fabric in which 0% by weight or more is polyethylene terephthalate. The polyester fabric has a fineness of 0.5 to 2.0 de l and a fiber length of 25 to 5.
5 van is preferred. Further, the copolymerized polyester fabric is preferably one that can be thermally softened or melted by moist heat treatment at 120° or higher, which is the usual high-pressure dyeing temperature for polyester fibers, and preferably has the same fineness and fiber length as the above-mentioned polyester fabric.

・By using 4-butanediol, diethylene glycol, triethylene glycol-tetraethylene glycol + neopentyl glycol, etc. as the glycol component, and combining various types of these monomers and their copolymerization ratios, the glass transition point and melting point can be adjusted to a fairly arbitrary value. Change to be able to. For example, terephthalic acid-isophthalic acid-1,4-butanediol copolymer, terephthalic acid-isophthalic acid-ethylene glycol-4-butanediol copolymer, terephthalic acid-isophthalic acid-ethylene glycol-diethylene glycol copolymer, A terephthalic acid-adipic acid-ethylene glycol-1,4-butanediol copolymer and the like are mentioned as materials for making the above-mentioned copolymerized polyester fabric. Among them, copolyesters consisting of terephthalic acid, isophthalic acid, 1,4-butanediol, and a glycol component other than polyether have good melt spinnability and stretchability.

は相当具なる。It is preferably used from the viewpoint of adhesive properties. These copolymerized polyesters can be obtained by polymerization according to conventional methods for producing polyesters. However, the conditions for making the copolyester into fibers are quite different from those for ordinary polyester, that is, polyethylene terephthalate polyester.

Stretching is performed 1.1 to 3 times at a temperature of 0 to 60°C.

とびの発生しないミシン糸を得ることができなくなる。The above-mentioned blended yarn of polyester fabric and copolymerized polyester fabric requires a blending ratio of the copolymerized polyester fabric, that is, a weight ratio of the copolymerized polyester fabric to the weight of the blended yarn, from 0.2 to 10.0%. do. If the blending ratio of the copolyester fabric is less than 0.2% by weight, the copolyester fabric is later deformed by heat or melting through moist heat treatment such as high-pressure dyeing, thereby increasing the bending rigidity of the sewing thread. , it becomes impossible to obtain sewing thread that does not cause skipped stitches even when used in high-speed sewing machines.

になる。On the other hand, if the blending ratio exceeds 10.0% by weight, the amount of copolymerized polyester fabric appearing on the surface will increase, and adhesion will easily occur between yarns during moist heat treatment such as high-pressure dyeing.
This will cause trouble in the subsequent winding process, etc.

The high-pressure dyeing or moist heat treatment is preferably performed at a temperature of 120° C. or higher.

所（鵬製純曲げ試験機を用いて測定される値である。As a result, the copolymerized polyester fabric in the blended yarn is thermally softened or melted to adhere to the polyester fabric or deform to fill the interfiber voids. By deforming this copolymerized polyester fabric, the bending stiffness of the sewing thread can be increased to 10, Of -Cm2/cie
The bending rigidity obtained was 10.0.
Polyester sewing thread with a value of 2.cm2/ae x to-6 or more exhibits excellent performance in that skipped stitches are less likely to occur even when used in high-speed sewing machines. Due to the low dyeing or moist heat treatment temperature, sufficient deformation of the copolyester fabric cannot be obtained, and therefore the bending rigidity is 10.0.
? - A polyester sewing thread having a Cm2/cie X of less than 10-6 cannot sufficiently prevent skipped stitches during high-speed sewing. The bending rigidity is a value measured using a pure bending tester manufactured by Kato Iron Works (Peng).

、乾熱処理によってもよい。Stitch skipping occurs when the sewing machine needle passes through the fabric and rises from the lowest point, creating a loop created by the needle thread, which is caught by the tip of the needle in the case of lockstitching, and by the looper in the case of chainstitching, causing the needle to pass through the fabric and rise from the lowest point. This occurs when the loop is not formed to be captured by the tip or looper. However, since the sewing thread of the present invention is made of spun yarn, unlike sewing thread made of filament thread, the fibers may melt due to friction with the needle hole or return when the sewing machine needle rises, resulting in a smaller loop. This is unlikely to occur, and the copolymerized polyester fabric will be thermally softened or melted, resulting in a bending stiffness of 10.0? -cm
2/ae x 10", so
Since the loop is less likely to twist and is formed into a shape similar to an elastane curve that is easily captured by the tip or loop, it can withstand high-speed sewing and is less prone to skipped stitches. As can be seen from this, the deformation due to thermal softening or melting of the copolymerized polyester fabric in the sewing thread of the present invention is preferably caused after twisting in the case of twisted yarns, and by high-pressure dyeing or moist heat treatment, but dry heat treatment It may also be done by

0740, a copolymerized poly(q)ester having a molar ratio of 1,4-butanediol/ethylene glycol of 97/3 was produced. Next, this polymer has 420 pores.
Melt spinning was performed using a spinneret at a spinning temperature of 250° C. to obtain an undrawn yarn with a filament denier of 56e. This undrawn yarn was pulled together to form a tow, drawn at a drawing temperature of 50° C. and a draw ratio of 4 times to give a push crimp of 11 threads/25 m5, and then cut into 44111I staples. Using the obtained copolymerized polyester yarn and regular polyester yarn 1.2 de A twisted yarn was produced. After this twisted yarn was made into cheese, it was dyed at a temperature of 130° C. for 30 minutes, and finally a silicone oil was applied to make it into sewing thread. Using this sewing thread with a 3-kiku flat seamer, make two layers of tricot knitted fabric at 5000
The sewing machine was sewn for 1 minute at a speed of stitches/minute, and the rate of skipped stitches (%) was measured during that time.
