Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pantyhose having excellent wearing functionality and fashionability. More specifically, the present invention relates to panty hose having extremely high transparency, extremely high fit and stretchability, and having a soft feeling.

[0002]

2. Description of the Related Art In recent years, a covering elastic yarn, in which an elastic yarn is used as a core yarn and a non-elastic thermoplastic synthetic filament yarn such as polyamide or polyester is wound as a covering yarn, is used as a knitting yarn. The type of pantyhose has become the mainstream of pantyhose due to its high stretchability and good fit.

Among them, the single covering elastic yarn (hereinafter referred to as SCY) formed by winding the covering yarn in a single winding is more productive than the double covering elastic yarn (hereinafter referred to as DCY) formed by winding the covering yarn in double. Since this is high and the production cost is low, the support type pantyhose made by alternately knitting this SCY and multifilament yarn such as polyamide yarn or polyester yarn or its processed yarn can be manufactured relatively inexpensively, Since it has good properties and has a soft texture, it has been widely used in general.

However, from the point of view of women's stockings that are required to have high fashionability and high functionality, this SCY interlaced support type pantyhose has a problem that transparency is considerably low, and further, elasticity, There has not yet been obtained anything that is fully satisfactory in terms of fit, touch, texture, firmness and waist.

Furthermore, the stocking product having the legs of the SCY interlaced knitting tends to suffer from scratches during its production process and wearing, and there is a problem that productivity is lowered and wearing durability is poor.

For this reason, the filament fineness of the multifilament yarn used as the yarn for interlaced knitting may be reduced, for example, to have a fineness such as 12 denier, or the number of filaments may be reduced to, for example, 3 filaments. There have been some efforts to improve transparency by means.
Still, it is difficult to obtain a sufficient level of transparency,
In addition, satisfactory products such as durability, touch and texture have not been obtained.

On the other hand, as for SCY, the elastic yarn of the core yarn is thinned, the yarn fineness of the covering yarn is lowered,
In addition, a method of reducing the number of filaments of the covering yarn has been devised to improve the transparency, but conversely, there is a decrease in stretchability, a decrease in fit, an increase in core breakage, and a decrease in durability. Problems like drop
Furthermore, the softness of the texture is impaired, and the graininess is increased, so that a satisfactory product is not obtained.

Further, there is a method of considerably increasing the number of coated twists to reduce the floating of the coated yarn, but if the number of coated twists is increased, the SCY torque increases, and kinks and creases are generated during knitting. There is a problem that the disorder of the knitting surface becomes large at the same time that the uprightness is lowered and a product defect is caused, and further, the softness of the texture is deteriorated.

[0009]

Therefore, the present invention solves the above-mentioned drawbacks of the prior art and maintains the stretchability and fitability of a support type pantyhose made by interlacing SCY while maintaining good stretchability and fitability. Its main purpose is to dramatically improve transparency, smoothness and smoothness, and proper elasticity and waist.

Another object of the present invention is to provide a high-class women's pantyhose which has a soft wearing feeling, is less likely to cause dents, has high durability, and has a beautiful knitted surface.

[0011]

In order to achieve this object, the present invention provides a core yarn of 8 to 40 denier made of elastic fiber and a filament yarn of thermoplastic synthetic polymer having a total fineness of 5 to 15 denier. Alternating knitted fabric of single-covering elastic yarn wound singly with a coating twist of 2400 t / m or less and monofilament yarn of 8 to 15 denier made of thermoplastic synthetic polymer and having substantially no crimp It consists of panty hose with legs.

In particular, the monofilament yarn is a polyamide monofilament yarn containing substantially no matting agent, and 0.01 to 3.0 with respect to the polyamide.
The polyamide monofilament yarn is preferably composed of a polyamide composition containing the acid amide compound represented by the following general formulas I and II in a weight percentage.

[0013]

[Chemical 3] (However, R1 and R4 represent an alkyl group having 10 to 20 carbon atoms, R2 and R3 represent a hydrogen atom, a methyl group or an ethyl group, and n represents an integer of 1 to 10.) Further, the single covering elasticity The elastic fibers of the yarn are polyurethane elastic fibers, and the wound filament yarn contains 0.01 to 3.0% by weight of the acid amide compound represented by the general formula I or II with respect to the polyamide. It is preferably a polyamide multifilament yarn of 2 to 8 filaments composed of a polyamide composition.

The yarn for knitting used in the present invention must be a monofilament yarn made of a thermoplastic polymer and having a total fineness of 8 to 15 denier and having substantially no crimp.

As this thermoplastic polymer, nylon 6 is used.
And polyamide such as nylon 66, polyester such as polyethylene terephthalate and polybutylene terephthalate, polyolefin such as polyethylene, polyacrylonitrile, and the like. Among them, they are excellent in dyeing properties, mechanical strength, friction properties and the like. Polyamide is preferred.

The total fineness of the monofilament interlaced yarn must be 8 to 15 denier, and especially 10 to 10 denier.
13 denier is preferable in order to further improve durability, transparency and touch. If it is less than 8 denier, the transparency is excellent, but the practical durability is significantly reduced.
On the other hand, if it exceeds 15 denier, the desired transparency cannot be obtained and the texture becomes coarse and hard.

Here, "having substantially no crimps" means crimps such as false twist crimping, rubbing crimping, indentation crimping and the like, and coiled crimps such as composite yarns. It means that there is no contraction.

It is preferable that the monofilament yarn does not substantially contain a matting agent such as titanium oxide in order to further improve the transparency.

When polyamide monofilament yarn is used, it may contain 10% by weight or less of a copolymerization component, or may contain 0.01 to 3.0% by weight of the above-mentioned general formulas I and II. By containing an acid amide compound having a, it is preferable to suppress crystallization and improve the transparency of the fiber substrate, but the physical properties of the fiber, for example, in the sense of suppressing changes in the strength and elongation characteristics, shrinkage characteristics and the like. The latter containing an acid amide compound is more preferable.

This acid amide compound is used as an additive for improving the strength / elongation property, transparency, surface gloss or dyeing sharpness of polyamide fibers, as disclosed in JP-B-44-9825 and JP-A-53-437253. JP-A-58-
It is known and described in Japanese Patent No. 132137. This acid amide compound, when used in combination with a polyamide-based monofilament yarn for interknitting of an extremely coarse knitted fabric such as a women's stocking, has a conventionally known effect, Another effect is that it has a soft feel and feel.

The amount of the acid amide compound is preferably 0.01 to 3.0% by weight based on the polyamide fiber, and particularly preferably 0.1.
1 to 2.0% by weight is suitable. If the blending amount is too small, the effects of reducing the feeling of roughness and improving the flexibility are insufficient. On the other hand, if the amount is too large, the stability of yarn production and the uniformity of fibers are deteriorated, and further, the strength and elongation characteristics and the elongation stress characteristics are deteriorated, and the characteristics as a fiber product are deteriorated.

On the other hand, polyurethane elastic fibers called "spandex" are suitable for the SCY core yarn used in the present invention, but other elastic fibers such as polyamide elastomer elastic fibers or polyester elastomer elastic fibers are preferable. May be.

It is necessary that the total fineness of the elastic fiber is 8 to 40 denier, and further 10 to 30 denier is preferable in order to further improve the transparency, durability and fitting property.

When it is less than 8 denier, the transparency is good, but the yarn strength is insufficient, and troubles such as core yarn breakage during knitting are likely to occur, and at the same time, the durability of the product knitted fabric is reduced, and the product as a product is also reduced. Insufficient fit and elasticity.

On the other hand, if it exceeds 40 denier, the desired sufficient transparency cannot be obtained and, moreover, the soft feeling is deteriorated and the product becomes rough and hard.

Further, it is necessary to use, as the coating yarn, a filament yarn made of a thermoplastic polymer and having a total fineness of 5 to 15 denier.

Examples of the thermoplastic polymer include the same polymers used as yarns for interlace knitting, but polyamides such as nylon 6 and nylon 66 are preferable for the same reason as described above. When using a polyamide, the polymer composition may be substantially free of matting agent,
A copolymerized polyamide containing 10% by weight or less of a copolymerization component may be used, and the content of the copolymerized polyamide is 0.01 to
It may be used in a polymer composition containing 3.0% by weight of the acid amide compound represented by the general formula I or II. In particular, it is preferable to use the polyamide composition containing the acid amide compound in order to achieve the object of the present invention.

The total fineness of the coating yarn needs to be 5 to 15 denier, especially 7 to 13 denier.
It is preferable in order to further improve transparency and obtain excellent durability and wearing feeling. When it is less than 5 denier, the covering property is deteriorated and the durability is deteriorated. On the other hand, if it exceeds 15 denier, the SCY becomes too thick, the desired high transparency cannot be obtained, and the texture of the product is impaired.

The number of single filaments of this multi-filament yarn is preferably 2 to 8 from the viewpoint of improving the covering property, transparency and soft feeling. With one piece, the covering property is poor and there is a problem in durability, and the soft feeling is easily impaired. On the other hand, when the number is 9 or more, the covering property and the soft feeling are improved, but the transparency is lowered and the scratches are likely to occur.

The number of coating twists for winding the multifilament yarn around the core yarn needs to be 2400 t / m or less, and particularly preferably 2200 t / m or less. SC obtained when the number of coated twists exceeds 2400 t / m.
The torque of Y increases and kinks and chatters occur during knitting,
There arises a problem that thread breakage is induced, and that the billi (snarl) is knitted to cause a product defect. Furthermore, if the number of coated twists is too high, the torque of SCY becomes excessive, and the knitting surface becomes disturbed when it is made into stockings, which impairs the cleanness of the knitting surface. There is also a problem that it becomes hard and the softness of the texture of the stocking product is impaired.

[0031]

As described above, according to the present invention of claim 1, in a support-type pantyhose in which SCY and filament yarns are interwoven, the interlacing yarn has a substantial crimp of 8 to 15 denier. By using a monofilament yarn that is not used, and further by using this monofilament interlacing yarn in combination with SCY having a specific yarn constitution to form a knitted leg part fabric, extremely high transparency and extremely high fit and stretchability are obtained. In addition, it is possible to obtain a panty hose that has high durability, excellent touch, soft texture, firmness and waist, and is resistant to scratching and high in durability.

That is, in the conventional knitted fabric formed by alternately knitting SCY and multifilament yarn (or processed yarn thereof), as shown in FIG. 2, since the women's stocking is a coarse knitted fabric. The individual yarns forming the interlaced yarns are scattered and spread in the knitted fabric loop, and the transparency of the knitted fabric is greatly reduced.

Furthermore, since the individual yarns that have come apart and spread in the knitted fabric loop are apt to be caught, crevices are likely to occur and the durability is poor.

In the present invention, however, the yarn for interlaced knitting is 8
Since a monofilament yarn having substantially no crimp of ˜15 denier is used, there is no looseness of the single yarn in the knitted fabric and the space in the knitted fabric loop is maintained as shown in FIG. Therefore, high transparency can be obtained. further,
Since the single yarn of the interlaced yarn does not come apart and the crimp does not float up, it is less likely to get caught, and the occurrence of scoring is suppressed to improve the durability. It is possible to obtain a stocking knitted fabric with a proper elasticity and waist that was not there. Moreover,
Since it does not have crimps, the knitting does not disturb the knitted fabric, the knitted fabric is flat and beautiful, and the transparency does not deteriorate due to the crimps.

In the conventional case where multifilaments (or their processed yarns) are used as the yarns for interlaced knitting, there are many problems in that the yarn breakage and the hole formation of the knitted fabric are likely to occur due to the filament breakage in the stocking knitting process. Since a monofilament is used in the present invention, such troubles at the time of knitting can be greatly reduced, and the knitting property can be improved.

Further, as the SCY, the SCY having a yarn structure in which the core yarn of the elastic fiber having a denier of 8 to 40 and the covering yarn of the filament yarn having a total fineness of 5 to 15 denier is used. Combined with the use of a specific monofilament yarn that has substantially no crimp at 8 to 15 denier, the transparency of the knitted fabric is remarkably improved, and further, sufficient elasticity and fit are obtained. A knitted fabric having a property can be obtained.

Further, since it is not necessary to increase the number of covering twists of SCY to more than 2400 t / m in order to improve transparency, the torque of SCY does not increase, and the occurrence of kinks and creases during knitting is suppressed. In addition, it is possible to suppress poor knitting property and product defects, and obtain good stocking products with good productivity and no defects.

In the present invention of claim 2, since the monofilament yarn of the interlaced yarn is a polyamide monofilament yarn substantially containing no matting agent, the transparency of the yarn itself is improved and the knitted fabric is transparent. The sex can be further enhanced.

According to the present invention of claim 3, 0.01 to 3.0% by weight of the general formula I or II is further added to the polyamide.
Since a polyamide monofilament yarn made of a polyamide composition containing a specific acid amide compound represented by is used, crystallization of the monofilament yarn is suppressed,
Not only is the transparency of the polymer matrix improved, but also the hardness of the knitted fabric is suppressed, the roughness due to the unevenness of the knitted fabric is reduced, and the flexibility is improved.

By suppressing the feeling of roughness and improving the flexibility, it is possible to obtain an effect that the entire knitted fabric has an extremely soft feel and is smooth and smooth to the touch. As a result, according to the present invention of claim 3, By using a monofilament yarn for knitting, in addition to obtaining high transparency and fitability, a polyamide of a specific composition is further used to form a multifilament yarn (or a processed product thereof) for a yarn for knitting. It is possible to obtain a knitted fabric having a soft feeling comparable to or superior to that of the conventional SCY interlaced knitted fabric using a yarn.

Furthermore, since a specific acid amide compound is contained without containing a matting agent, the strength and elongation characteristics are improved, and
A knitting yarn of ˜15 denier and a fine filament monofilament yarn can be a product knitted fabric having practically satisfactory durability.

Furthermore, the addition of the above-mentioned acid amide compound improves the transparency and the sharpness of dyeing, further improving the transparency of the knitted fabric, and the product pantyhose after dyeing is excellent in the vivid color. Become.
