Field of the Invention The present invention relates to a polyamide fiber having high toughness and high transparency, and more specifically, a polyamide fiber which is excellent as a material for a clothing system excellent in high dyeing and vivid coloring and texture. It is about fibers.

布帛が望まれる傾向にある。2. Description of the Related Art Recently, in the field of clothing-based fabrics, there is a marked trend toward higher fashion, which is "not wanting to look more beautiful", but is not satisfied by the sole purpose of hiding or protecting the body. In particular, in areas where women's skin looks beautiful, especially in the field of underwear, stockings, etc., fabrics that do not have the transparency as in the past and are thick are shunned, have more transparency, and have superior color development. Fabrics tend to be desired.

る布帛を得ることはできなかった。As a method for solving these problems, for example, a method of reducing the total fineness of fibers to be used, or a method of reducing the number of single yarns with the same total fineness has been tried. However, in the former, there is a problem that the strength of the fabric is lowered, and in the latter, when the number of single yarns is reduced, the softness and the texture of the fabric are impaired, and if it is not sacrificed, it has excellent transparency. No fabric could be obtained.

Although a method of solving the above problems by utilizing the optical characteristics by changing the cross-sectional shape of the fiber as disclosed in Japanese Patent Laid-Open No. 8-132113 has been attempted, an apparent transparency can be obtained, but it comes from the fiber surface. Diffuse reflection causes glare on the surface of the fabric, which is not preferable especially in the case of stockings.

There is a method of adding or polymerizing a lubricant such as a diamide compound to a polymer as proposed in 132137 or JP-A-4-18118, but the effect of suppressing the crystallization and the effect of suppressing the formation of coarse crystals such as spherulites are sufficient. However, the transparency has not been remarkably improved, and the effect of improving the toughness is small.

フネス化が望まれる。As the needs of the clothing market, the demand for "more transparent and stronger" is increasing more and more in recent years as the thinning of the fabric is advanced by making the fabric finer in order to obtain a more transparent feeling. However, it is difficult to satisfy all of them practically, and further improvement of transparency and high toughness are desired.

とが困難である。The degree of polymerization of the polyamide of the present invention is generally such that fiber formation is possible, but it is preferable that the polyamide 98 has a relative viscosity of 98% sulfuric acid in the range of 2.4 to 3.5 and has a relatively low viscosity. However, the toughness of the polyamide filament yarn can be achieved up to 40 to 55, and the performance of the polyamide fiber of the present invention can be effectively exhibited. In order to dramatically improve the transparency and toughness of the polyamide fiber, it is necessary to use the diamide compound represented by the formula (1) and / or the formula (2) and the sorbitol compound represented by the formula (3) in combination. However, it is difficult to simultaneously obtain the high transparency and high toughness that are the objects of the present invention with other compounds.

Is. If the blending amount is too small, not only high transparency and high toughness, which are the objects of the present invention, cannot be obtained, but also high dyeing sharpness is deteriorated. On the contrary, if the blending amount is too large, not only the compatibility with the polyamide is lowered and the transparency is lowered, but also the spinning property is deteriorated due to coloring of the fiber by the additive and bleeding out.

ることが同時にできる。In the present invention, it is difficult to achieve the effect of remarkably improving the transparency and toughness by blending the diamide compound alone with the polyamide, but by using the sorbitol compound in combination therewith, it is possible to obtain a high transparency. And high toughness can be achieved, and in addition, excellent coloring and coloring properties and texture can be obtained. That is, the effect of suppressing the crystallization of the diamide compound acting on the polyamide is promoted by adding a sorbitol compound, and further by the interaction between the molten polyamide and the inherent higher-order structure formed by the sorbitol compound, At the same time, the crystal nucleation rate of the polyamide can be further accelerated.

のである。As a result, it is possible to suppress the generation and growth of spherulites, which are a higher-order structure of crystals, and to reduce the size, while further suppressing the crystallization of the polyamide. As a result, not only can diffuse reflection due to internal scattering of light due to coarse crystals be significantly suppressed, but at the same time, the surface shape of the polyamide fiber can be made smoother, and optical specular reflection can be achieved. Can also be improved.
Therefore, the transparency of the polyamide fiber can be remarkably improved.

等である。Furthermore, since it is possible to suppress the generation and growth of spherulites, which are coarse crystals in the crystal higher-order structure as described above, the higher-order structure of the polyamide fiber becomes more uniform and orderly,
At the same time, it is possible to significantly improve the toughness, which is a physical property, and further improve the coloring property by dyeing. In the present invention, it is necessary to mix the sorbitol compound with the diamide compound in the polyamide.
The sorbitol-based compound is represented by the formula (3), preferably 1,3,2,4-dibenzylidene sorbitol and 1,3,2,4-di- (P-methylbenzylidene). Sorbitol, 1,3,2,4-di- (P

It is required to be 1 to 3.0% by weight, and more preferably 0.05 to 1.0% by weight. Further, in order to maximize the high transparency and high toughness in the present invention, it is preferable that the additive, that is, the compounding ratio of the diamide compound and the sorbitol compound be 1: 0.05 to 1: 1. , And more preferably 1: 0.5 to 1: 1.

Here, the toughness {(g / d) × (%)} is the breaking strength (g / d) × breaking elongation (%). When the toughness is less than 40, it is substantially difficult to thin the fabric by fineness, which is the aim of the present invention, and it is difficult to remarkably enhance the transparency. Further, when the toughness is 55 or more, the Young's modulus of the polyamide fiber becomes excessive, and the softness (texture) characteristic of the polyamide fiber is impaired, making it unsuitable for clothing-based fibers such as women's underwear and stockings.

Further, the means for compounding the diamide compound and the sorbitol-based compound into the polyamide is a method of adding the compound before the polymerization of the polyamide or in the step of the polymerization step, and when the master chip in which the above compound is added to the polyamide at a high concentration is prepared and melt-spun is not used. Either a method of mixing with a modified polyamide so that a predetermined amount of the above compound is contained, or a method of adding the above additives to a polymer by using a powder jet color or the like at the time of melt spinning may be used.

A few fiber properties and a fabric property are shown in Tables 1 and 2.
As in Examples 1, 2, 3, and 4, the polyamide fiber according to the present invention has extremely excellent light transmission and reflection properties, so that the transparency is remarkably improved and the toughness is also extremely high. . Further, the dyeing clear color development and the texture are also excellent.

った。On the other hand, in the case of Comparative Example 1, that is, when the additive was not added, not only the transparency was considerably deteriorated, but also the high toughness could not be exhibited. When only the diamide compound is added to the polyamide as in Comparative Example 2, the transparency is improved as compared with Comparative Example 1, but the transparency is inferior as compared with Examples 1, 2, 3, and 4. The toughness was also low.

ネス化を同時に達成し得ることができる。In the present invention, it is difficult to achieve the effect of significantly improving the transparency and the toughness at the same time by blending the polyamide with only the diamide compound. However, it is necessary to use the sorbitol compound in combination therewith. This makes it possible to overcome the drawbacks of the conventionally known methods and achieve high transparency and high toughness at the same time.

Therefore, in order to obtain a more transparent feeling required by the recent needs of the clothing market, the cloth is obtained. It is possible to meet the demand for "more transparent, thinner and stronger" by making it possible to make the fabric thin by making the fineness of the above. Furthermore, since it is excellent in dyeing vivid color development and texture, it is possible to obtain a natural texture that complements the transparency.
