Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin traveler for a spinning machine, which is capable of lowering the running tension of a yarn in a twisted yarn and maintaining a stable running posture.

[0002]

2. Description of the Related Art Conventionally, metal travelers and resin travelers have been used as spinning travelers. However, since the resin traveler has a smaller specific gravity, it is possible to give a larger volume, so that the effect of air resistance is more effective. Therefore, it is widely used as a traveler for spinning machines for various kinds of fibers because of its advantages such as keeping reasonable contact with the ring, less wear, heat generation, less oil stain, and less fluctuation in tension.

Among various fibers, glass fiber yarn is particularly prone to fluffing, and therefore, it is required to improve the fluff quality as well as to increase the twisting speed.
Under such circumstances, the weight of the resin traveler has been further reduced, and the resin traveler designed into various shapes according to the yarn count (weight g per 1000) is used.

[0004]

Generally, a resin traveler for a spinning machine comprises a head portion 10, a body portion 11, a lower portion 12, an upper leg portion 13, and a lower leg portion 14 as shown in FIGS. 1 (a) and 1 (b). The inner surface of the head 10 serves as the thread passing portion 15. Such a resin traveler can reduce the running tension of the yarn in the twisted yarn as it is made lighter or thinner, and as a result, the fluff quality of the glass fiber yarn can be improved and the twisting speed can be increased. Although it is possible, on the other hand, the strength of the resin traveler is reduced, the running posture of the resin traveler in the twisted yarn becomes unstable, the degree of bending at the thread passing portion becomes large, and the fluff quality deteriorates. There is a fear.

The present invention has been made in view of the above circumstances, and it is possible to secure a desired strength while improving the fluff quality and increase the twisting speed, keep the running posture during twisting stable, and pass the yarn. An object of the present invention is to provide a resin traveler for a spinning machine, which can reduce the degree of bending in a part.

[0006]

In order to achieve the above-mentioned object, the present inventors have adjusted the weight of the resin traveler in accordance with the yarn count, and have the ratio of the thickness of the resin traveler to the height of the inner diameter changed. The inventors have found that it is necessary to regulate and have proposed the present invention.

That is, the resin traveler for spinning machine of the present invention is
The relationship between the traveler weight (M _TV ) and the yarn count (TEX) satisfies the formula M _TV ≦ 1.5 × (TEX / 1000), and the thickness (d) of the thread passage portion and the inner diameter Height (h)
Is satisfied, the relationship of d / h ≧ 0.25 is satisfied.

The spinning resin traveler of the present invention is characterized by being formed from one member selected from 6 nylon, 6.6 nylon and 4.6 nylon, and is used in the twisting process of the glass fiber yarn. It is characterized by being.

[0009]

The function of the resin traveler for the spinning machine of the present invention is such that M _TV ≤
Since the formula of 1.5 × (TEX / 1000) is satisfied, the running tension of the yarn in the twisted yarn can be lowered.

Further, as shown in FIG. 1, since the equation of thickness (d) of thread passing portion / height of inner diameter (h) ≧ 0.25 is satisfied, desired strength can be secured and running posture during twisting Can be kept stable and the degree of bending at the yarn passing portion can be reduced.

Further, the material of the resin traveler of the present invention is excellent in heat resistance, abrasion resistance and elasticity,
Nylon resins such as nylon, 6.6 nylon and 4.6 nylon are suitable, and the resin traveler of the present invention is particularly suitable for the production of glass fiber yarns where fluffing is likely to occur.

In order to reduce the weight of the resin traveler of the present invention, as shown in FIG. 2, the thickness (d) of the trunk portion, the lower portion and the lower leg portion lower than the thickness (d) of the thread passing portion is lower than that. ′) Should be thin.

[0013]

EXAMPLES The resin traveler for a spinning machine of the present invention will be described in detail below based on Examples and Comparative Examples.

First, three kinds of resin travelers (6
A glass fiber yarn having a yarn count of 69.25 TEX was twisted to produce a glass fiber yarn by using (Nylon), and the running tension of the yarn, the running posture of the resin traveler, and the amount of fuzz in the twisting process were examined.

[0015]

[Table 1]

As is clear from Table 1, in the resin traveler of Example 1, the running tension of the yarn was low, the running posture of the resin traveler was stable, and there was little fluffing.

On the other hand, the resin traveler of Comparative Example 1 is
Since the traveler weight was too heavy, the running tension of the yarn was high and there was a lot of fuzz. Further, in the resin traveler of Comparative Example 2, since the ratio of the thickness d of the yarn passing portion / the height h of the inner diameter was small, the running posture of the yarn was unstable, and again there was a lot of fuzz.

Next, three kinds of resin travelers (6
Nylon) was used to prepare a glass fiber yarn in which a glass fiber bundle having a yarn count of 22.5TEX was twisted, and the running tension of the yarn, the running posture of the resin traveler, and the amount of fuzz in the twisting process were examined.

[0019]

[Table 2]

As is clear from Table 2, in each of the resin travelers of Examples 2 and 3, the running tension of the yarn was low, the running posture of the resin traveler was stable, and there was little fluffing.

On the other hand, the resin traveler of Comparative Example 3 is
Since the traveler weight was too large and the yarn passing portion thickness d / inner diameter height h was small, the running posture of the yarn was unstable and fuzzing was large.

The running tension of the yarn is measured by measuring the running tension of the yarn above the snail wire, and when the value is TEX × 1.5 (g) or more, the value is high.
The case of less than EX × 1.5 (g) is shown as low.

As for the running posture of the resin traveler, the traveler in the twisted yarn is observed with a strobe, and the traveler is tilted, twisted,
Those with little vibration were made stable, and those with large tilt, twist, and vibration were made unstable.

Further, the amount of fluff was observed by visually observing the fluff on the surface of the pan, and the number of fluffs was 3 or more and less than 3 was small.

[0025]

As described above, the resin traveler for a spinning machine according to the present invention lowers the running tension during twisting, maintains a stable running posture, and suppresses the occurrence of fluff because the degree of bending at the thread passing portion is small. It is possible, and is particularly suitable as a resin traveler for a spinning machine for producing a glass fiber yarn in which fuzz is likely to occur.
