CONSTITUTION:Coated elastic yarn prepared by winding twisted yarn of thermoplastic synthetic yarn (e.g. polyamide yarn) having <=600D<1/2> (t/m) (D is denier of synthetic yarn for covering) to <=5,000D<1/2>(t/m) on core yarn composed of elastic yarn (e.g. polyurethane) in the direction opposite to twisting direction of the twisted yarn to give the objective pantie stockings.

Description

[Detailed Description of the Invention] [Industrial Application Field] This relates to pantyhose knitted using elastic fibers such as polyurethane as a core yarn and covered elastic yarns with thermoplastic synthetic fibers wrapped around them, and which have a silky luster. sex,
The present invention relates to pantyhose with high transparency and excellent uniformity in appearance and high durability.

[Conventional technology]

Women's pantyhose are often knitted using covered elastic yarn, but this covered elastic yarn is made of straight yarn (raw silk) of thermoplastic synthetic fibers mainly made of nylon, wrapped around spandex fibers such as polyurethane. )
Or, single or double wrapping of false twisted yarn.

As the covering yarn, almost untwisted yarn is used in order to sufficiently spread the single yarn and increase the covering effect. However, for this reason, when the knitted fabric is in a relaxed state, the single yarns of the covering yarn tend to lift up on the knitted fabric structure, causing kinks, resulting in defects and decreased durability. Also,
Transparency was poor due to the spread of the single yarn, and the luster was metallic, and a delicate satin-like silky luster could not be obtained.

Furthermore, the uniformity of the knitted fabric structure was impaired due to the spread of the single yarns, and the appearance of the two knitted fabrics was slightly disordered.

It has the disadvantage of lacking uniformity.

[Problem to be solved by the invention]

To provide pantyhose having a delicate satin-like silky luster, excellent transparency, good knitted fabric appearance uniformity, and less occurrence of defects and decrease in durability due to knitted fabric strain.

[Means to solve the problem]

The stocking part, the panty part, or both the stocking part and the panty part of the pantyhose are made of thermoplastic synthetic fibers with a twist count of 600 around a core yarn made of 8 elastic fibers.
/, /'i (t/m) or more, 5000/φte (t/m) or more
m) The following twisted yarns were covered and wound in a twisting direction opposite to this twisting direction. This problem is solved by constructing a pantyhose product using covered elastic yarn.

Here, D indicates the denier of the fiber used for coating.

[Effect]

The thermoplastic synthetic fibers used for the coating include polyamide fibers such as nylon 6 and nylon 66, and polyester fibers such as polyethylene terephthalate, but polyamide fibers are the most preferred in terms of dyeability, elasticity, and durability. Are suitable.

The thickness of the fibers is preferably 15 deniers or less from the viewpoint of transparency, but is not necessarily limited to this.

The elastic fiber of the core yarn is preferably polyurethane fiber, but
Other elastic fibers such as polyester and polyamide can also be used. Again, the thickness of the fibers is preferably 20 deniers or less, but is not necessarily limited to this.

600/J1 (t/11) or more in the present invention, 5
For heating below 000/J (t/m), it is preferable to use a double twister, but an up twister or a down twister can also be used. In addition, in the case of a high degree of combustion, it may be necessary to perform heat fixation to prevent twisting in order to avoid handling troubles due to torque development.

The relationship between the number of twists, silky gloss, transparency, and durability of the coating yarn of the present invention is shown in FIGS. 1 to 5.

Regarding silky gloss, as shown in Figure 1, the simple gloss strength gradually decreases as the number of twists increases, as shown by the three curves, and when it exceeds 5000/, /'i (t/m), the gloss decreases. The drop will be large. On the other hand, the delicate satin-like luster shows a change with a peak at about aooo/J (t/m) as shown by the b curve, and is 600/φ) (t/m).
If the twist is less than ), the simple luster is too strong and the subtle light is insufficient. On the other hand, if the twist exceeds 5000/J (t/++), the luster becomes too dull and the silky luster is lost.

When both the gloss strength and the subtle satin-like gloss are approximately 4 or higher, it can be said that the product has silky gloss.

That is, twisting less than 600/, /"i (t/m) results in a simple glossy yarn, and 5ooo/, /i5"" (
If the twist exceeds t/m), the gloss becomes too dull and silky gloss cannot be obtained.

For this, 600/J (t/*) more than 5000
When the twist is less than /J (t/m), a moderate degree of subtle silky luster is exhibited.

Regarding transparency, as shown in FIG. 2, it improves as the number of twists increases, and the transparency becomes clearly good when the twist is 600/J (t/m) or more. However, 5000/
, /T (t/m), the transparency becomes worse. This is due to an increase in the fineness of the covered yarn due to the high shrinkage rate of the twist due to a large number of twists, and a bulge of the covered yarn as a whole due to excessive convergence.

Here too, it can be said that transparency is good if the transparency rank is 4 or higher, and 600/J (t/m) or higher is 5.
ooo/i wm) or less indicates good transparency.

The uniformity of the knitted fabric improves as the number of twists increases as shown in Figure 3, and the uniformity is good at 600/, 7'5-'' (t/nt) or more, but at 5000/φ ) (
t/m), a decrease is seen on the contrary. As the yarn converges and the torque of the yarn decreases, twisting of the stitch loops disappears, making the knitting structure more uniform and improving the uniformity of appearance. On the other hand, excessive twisting causes the yarn to become coarsely hardened, and the accompanying torque generation causes the yarn to lose its flexibility and twist the stitch loops, causing disturbances in the knitting structure. By making the twisting direction and the twisting direction of the coating winding opposite.

The effect is clearly occurring.

Regarding the uniformity of these 9 knitted fabrics, it can be said that a rank of 4 or higher is good.

In the case of twisting in the same direction, the torque of the yarn is generally strong and the twist of the stitch loops is strong, making it impossible to obtain a uniform knitted fabric. As for durability, as shown in Fig. 4, the occurrence of cracking decreases significantly when the load exceeds 600/J (t/m). On the other hand, the strength of the covered yarn released from the stocking improves somewhat as the number of heating increases, as shown in FIG.

A slight decrease is seen when exceeding 4000/, /'i (t/m).

When the speed exceeds 5ooo/, /i ton (t/m), the decrease becomes large.

In this way, when the twist is soo/, /'ii (t/m) or more, the occurrence of kinks is significantly reduced, and the strength as a covered elastic yarn is slightly increased, resulting in improved durability. However, when the number of twists exceeds 5000/J (t/m), the strength of the covered yarn is greatly reduced, although the occurrence of strain is small.

Overall, the durability is poor.

As above, 600/,, /”5” (t/m)
By using a yarn with a twist number in a range of 5000/J (t/m) or less, and by performing coating winding with the twist in the opposite direction to this twist direction.

A pantyhose product with good silky luster, excellent transparency, good uniformity of appearance, and high durability is obtained. In the case of single covering, the present invention is applied by using an S-twist covered yarn to wrap the cover in the Z-twist direction, or by using a Z-twist covered yarn to wrap the cover in the S-twist direction.

In double covering, an S-twist undercover yarn is used to undercover in a Z-twist direction, and then a zF? Either use the top covering yarn of No. 8 to cover the S twist direction, or use the Z twist bottom covering yarn to cover the S twist direction, and then use the S twist top covering yarn to cover the S twist direction. Perform overcoating in the twist direction. It is knitted using these covered elastic yarns.

In addition, using any thread as the lower covering thread, only the upper covering thread is 600/
, /'Er (t/m) more than 5000/, /'5"
(t/m) Using the following twisted yarns, overcoating was performed in the direction opposite to this twisting direction. Knitting using double covering yarn is also applicable. Furthermore, it is of course possible to use different numbers of twists for the yarns of the upper and lower covers within the scope of the present invention.

The number of twists in the wrapping of the covering is 1 for a single covering.
Approximately 700 t/m is good, but it may be selected appropriately depending on the thickness of the fibers used. For double covering, number of lower twists is 2400 t/m, number of upper twists is 2040 t/I1
About 1 is good, but this can also be arbitrarily selected.

On the other hand, two-knitting may be performed using only such single covering or double covering covered yarn, but interlaced knitting with other yarns is also applicable.

Although pantyhose have been described above, the present invention can also be applied to stockings, and the term "stockings" here refers to long stockings including socks, knee-high socks, knee-high socks, and garter stockings.

Pantyhose include those in which the leg portion and panty portion are knitted with the same yarn, such as see-through panties and tights, and those in which the leg portion and panty portion are knitted with different yarns.

Regarding the number of twists, the value obtained by multiplying the number of twists (t/+n) by the square root of the denier, 5, is generally called the twist coefficient.

) and 2000 t/m (6325) (numbers in parentheses represent twist coefficient), 20 denier polyurethane yarn was coated with S twisted yarn at 2400 t/m in the Z twist direction, and further Z Twisting the twisted yarn in the direction of S twist 2040
Eight types of double covered yarns were made by overcoating at t/m.

In addition, in the case of heating of 1000 t/m or more, heat setting was performed on a heating machine to reduce the torque. The draft ratio of the polyurethane thread during covering was 3.2 times.

See-through type pantyhose were made by knitting the double-covered yarn and nylon 15-denier 3-filament twisted yarn of 200 t/m alternately to form a relief part and a panty part.

These pantyhose were evaluated for wearing, and the silky gloss, transparency, uniformity of the two knitted fabrics, and durability were evaluated. The results are shown in Tables 1 and 2.

Durability was determined by wearing 10 pairs of shoes for 10 days.

(6928) and single covering the 20 denier polyurethane yarn at a rate of 1700 t/m with the S-twisted yarn in the zg direction and the Z-twisted yarn in the S-twisted direction.

Furthermore, for twisted yarns of 200 t/m and 700 t/m, the twist direction of the covered yarn and the twist direction of the coating are the same.

That is, single covering was performed for the S-twisted yarn in the S-twist direction and for the Z-twisted yarn in the Z-twist direction. In this case as well, the number of twists during single covering was 1700 t/+.

In addition, in the case of heating at 1200 t/m or more, heat centrifugation was performed on the heating machine to reduce the torque. Similarly, the draft ratio of polyurethane during covering is 3.
．． That's twice as much.

S-covered yarn and Z-covered yarn of each of these single covered yarns
Pantyhose whose leg portions were made by alternately knitting the covered yarn and the covered yarn were made. Tables 3 and 4 show the results of wearing evaluation of these pantyhose.

Durability was evaluated by wearing 10 pairs for 10 days.

Table 3 Table 4 Note) The twist of the main covering yarn and the twist of the covering are in the same direction.

As in Example 1, the evaluation was conducted using two samples of the present invention, as shown in Tables 3 and 4.
Nos. 11 and 12 were excellent pantyhose exhibiting good quality in all of silkiness, transparency, knitted fabric uniformity, and durability. On the other hand, the comparative example It 13.1
Both samples 4.15 and 16 had poor quality. In addition, in the case of covers 17 and 18, which were covered in the same direction, the stitch loops were disordered due to the twist of the stitches, and the appearance of the two knitted fabrics was not uniform.
The quality was poor.
