Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a twisted yarn having a fineness and a high tenacity, and more particularly, to a twisted yarn which is preferably applied as a sewing thread for sewing requiring such a function.

[0002]

[Prior art]

 Conventionally, natural fibers such as cotton and silk and synthetic fibers such as nylon and polyester have been used for sewing threads.

On the other hand, in sewing, high-strength sewing threads are required due to diversification of fabric thickness and number of fabric layers and high-speed sewing.

However, the conventional natural machine sewing thread does not satisfy the above-mentioned requirements, and the synthetic machine sewing thread also has a problem that thread breakage due to friction with the cloth or the sewing needle occurs. there were.

In order to solve such a problem, recently, a sewing machine yarn (for example, Japanese Patent Laid-Open No. 4-11038) obtained by twisting a polyester multifilament yarn and a polyester spun yarn has been disclosed. Although it can be manufactured at low cost, it is still unsatisfactory in terms of providing a sewing thread having fineness and high tenacity.

[0006]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object thereof is to provide a twisted yarn having fineness and high strength, which is suitably applied as a sewing thread for sewing. That is.

[0007]

[Means for Solving the Problems]

 That is, the present invention relates to a twisted yarn characterized by twisting a fluid entangled yarn and a multifilament yarn. Furthermore, the fluid entangled yarn and the multifilament yarn have a triplet structure with a composition ratio of 1: 2 or 2: 1, and the fineness of the fluid entangled yarn is 200 to 300 denier, and The present invention relates to a twisted yarn, wherein the multifilament yarn comprises 1 to 4 multifilament yarns having a fineness of 150 to 300 denier.

[0008]

[Action]

 In the above-mentioned configuration, the fluid entangled yarn means, for example, a core yarn and a cover yarn which are separately fed in a state of overfeed (super-supercharged yarn) in a hollow pipe, and to a yarn running in the pipe This is because the compressed air is blown from diagonally behind and the yarn is disturbed. In the fluid entangled yarn of the present invention, it is preferable to use synthetic fibers such as polyester for both the core yarn and the cover yarn. The fineness of the fluid entangled yarn is preferably 200 to 300 denier, and if the fineness is less than 200 denier, the desired tenacity cannot be obtained although the fineness is obtained. If it is more than 300 denier, the high tenacity is high. Although it is obtained, the desired fineness cannot be obtained.

Further, it is preferable to use synthetic fibers such as polyester for the multifilament yarn as well, and 1 to 4 multifilament yarns having a fineness of 150 to 300 denier are used as the multifilament yarn constituting the present invention.

Further, in the above configuration, when twisting the fluid entangled yarn and the multifilament yarn, the twisting direction may be right twist (S twist) or left twist (Z twist). The direction is not limited. Further, the twisted yarn of the present invention is preferably a triple twist in which the composition ratio of the fluid entangled yarn and the multifilament yarn is 1: 2 or 2: 1.

Hereinafter, the present invention will be described with reference to examples.

Example 1 As Example 1 of the twisted yarn of the present invention, first, a fluid entangled yarn 2 constituting the twisted yarn 1 shown in FIG. Each was made using a 48 filament polyester filament yarn. The processing conditions for the fluid entangled yarn 2 are as follows: 15% polyester filament raw yarn of 150 denier 48 filament on the core yarn side and 8% polyester filament raw yarn of 70 denier 48 filament on the cover yarn side. While being guided into the hollow tube, the yarn was treated at a yarn speed of 350 m / min while sending compressed air of 6.5 kg / cm ² obliquely backward from the yarn. Further, a multifilament yarn 3 constituting the twisted yarn 1 shown in FIG. 1 was produced by using four polyester filament raw yarns made of Toray and made of 100% polyester and 150 denier 48 filaments. Next, the fluid entangled yarn 2 and the multifilament yarn 3 were triple twisted with a composition ratio of 1: 2. As such processing conditions, a twisted yarn 1 was twisted in the S direction to 570 T / m and then twisted in the Z direction at 340 T / m to obtain a twisted yarn 1 as Example 1 of the present invention shown in FIG.

[0012]

Example 2 Twisted yarn as Example 2 of the present invention shown in FIG. 2 was carried out in the same manner as in Example 1 except that the fluid entangled yarn 2 and the multifilament yarn 3 were triple twists with a composition ratio of 2: 1. Got 4.

[0013]

Comparative Example 1 In Comparative Example 1, a 100-ply polyester, polyester filament raw yarn of 150 denier 48 filament and a polyester denier yarn of 70 denier 48 filament manufactured by Toray Co., Ltd. were quadruple-twisted. I got a yarn.

[0014]

[Comparative Example 2] A twisted yarn of Comparative Example 2 was obtained in the same manner as in Comparative Example 1 except that triple twist was used.

Table 1 shows the results of Example 1, Example 2, Comparative Example 1, and Comparative Example 2.

[0016]

[Table 1]

As is clear from the results in Table 1, the breaking strengths of Examples 1 and 2 were both superior to the breaking strengths of Comparative Examples 1 and 2.

[0018]

【The invention's effect】

 As described above, according to the present invention, it is possible to provide a twisted yarn having a fineness and high strength, and it can be suitably applied as a sewing thread used for sewing thick fabrics, high-speed, high-tension sewing, etc. become.
