- the composite fiber of Patent Document 3 has a drawback that the production apparatus becomes complicated and thus has a high cost. Also, due to the difference in water absorption ability of the polymer used for the core part and the sheath part, during the hot water treatment such as scouring and dyeing Since the hygroscopic resin in the core part absorbs water and swells greatly, the fiber surface is cracked and the core polymer is eluted.
- Patent Document 1 Although the method of Patent Document 1 is excellent as a hygroscopic fiber, since polyamide pyrrolidone is added based on polyamide 6 as a polyamide, for example, in recent years, a tight-fit T-shirt or the like is worn as a fashion trend. With an increasing number of women, and with an increasing demand for mold bras that are hard to crack on the outer, heat resistance to mold processing was not sufficient.

- the polyamide 56 in the present invention it is preferable to use a polymer having a 98% sulfuric acid relative viscosity of 2.4 or more and 2.6 or less in order to effectively express the effect of the present invention.
- the 98% sulfuric acid relative viscosity is in this preferred range, it is easy to obtain sufficient strength when it is made into a fiber.
- the extrusion pressure of the molten polymer at the time of spinning and the rate of increase over time are moderate, and it is not necessary to overload the production facility and shorten the exchange period of the die, so that high productivity is maintained.
- the 98% sulfuric acid relative viscosity means a value obtained by dissolving 25 g of fiber in 25 ml of 98% sulfuric acid and measuring at 25 ° C. using an Ostwald viscometer.
- the polyamide 56 in the present invention may be copolymerized or mixed with the second and third components in addition to the main component within the range not departing from the object of the present invention.

- ⁇ MR is an index for obtaining comfort by releasing moisture in the clothes to the outside air when the clothes are worn, and is 30 ° C. ⁇ 90% RH when performing light to medium work or light to medium exercise. It is a difference in moisture absorption between the temperature in the garment represented and the outside air temperature humidity represented by 20 ° C. ⁇ 65% RH.
- this ⁇ MR is used as a parameter as a measure of moisture absorption performance evaluation. The larger the ⁇ MR, the higher the moisture absorption / release capacity, and the better the comfort when worn.
- polyamide fibers such as polyamide 6 and polyamide 66 have ⁇ MR of about 1.5 to 2.0.
- the polyamide fiber of the present invention has a high moisture absorption / release property with a ⁇ MR of 3.0% or more. If ⁇ MR is less than 3.0%, the moisture absorption and desorption of the same level as that of ordinary polyamide 6 or polyamide 66 only remains, and there is a problem that comfort at the time of wearing is not high. Although there is no limit on the upper limit, even if it is made too large, a great difference in sensation does not occur, and ⁇ MR of about 20% is sufficient.
- the moisture absorbing / releasing ability of the polyamide fiber largely depends on the crystal structure in the fiber.
- the reversible moisture absorption and desorption ability greatly depends on the ratio of the amorphous part in the fiber. Accordingly, in order to improve the ⁇ MR of the polyamide fiber, it is important to increase the ratio of the amorphous portion within a range not impairing the spinning operability and the yarn quality.
- the birefringence of a crystalline synthetic fiber is large for a fiber in which the molecular chain is advanced, and is small for a fiber in which the orientation is not advanced.
- the molecular chain orientation is an important parameter because it greatly affects the water absorption rate of the fiber as described below. That is, the moisture absorption of the polyamide fiber is divided into two cases, when the water is coordinated and bonded to the amide group of the polyamide, and when the polyamide molecular chain in the fiber is taken into the amorphous part where it exists in a random state. In some cases, however, the ratio of the amorphous portion in the fiber greatly affects the ⁇ MR value.
- Polyamide fibers have a large proportion of crystal parts, a small proportion of amorphous parts that can retain moisture, and when there are many crystal parts, the moisture on the fiber surface reaches the vicinity of the amide groups in the polyamide fibers. Can not do it.
- the orientation of the molecular chain can be expressed by birefringence, and when the birefringence increases, the moisture absorption rate tends to increase.
- the moisture absorption rate is too large, the spinning oil and the moisture in the air are excessively absorbed, resulting in the result.
- the yarn swells and cannot be stably spun, and the dispersion of the fiber structure increases and the quality deteriorates.
- birefringence becomes small, the orientational crystallization of the molecular chain in the fiber proceeds and the moisture absorption rate tends to decrease.
- the birefringence is preferably 30 ⁇ 10 ⁇ 3 or more and 40 ⁇ 10 ⁇ 3 or less, and within this range, the spinning operability and yarn quality of the polyamide 56 fiber are not impaired.
- a polyamide 56 fiber having a high moisture absorption / release property can be obtained.
- the polyamide fiber of the present invention can be produced by the following method.
- FIG. 1 is a schematic view showing an example of a synthetic fiber production process according to the present invention.
- the melted polyamide is measured and transported by a gear pump, discharged from the spinneret 2, cooled by blowing air with a cooling device 3 such as a chimney to cool the yarn to room temperature, and supplied with an oil supply device 4. Then, the particles are converged together, entangled by the first fluid entanglement nozzle device 5, passed through the take-up roller 6 and the drawing roller 7, and then drawn according to the ratio of the peripheral speeds of the take-up roller 6 and the drawing roller 7. Further, the yarn is heat set by the drawing roller 7 and wound by a winder (winding device) 8.
- the die discharge linear velocity is set to 14 m / min or more and 30 m / min or less.
- the die discharge linear velocity is a value obtained by dividing the discharge volume per unit time of the polymer in the die hole for spinning the yarn by the die hole area, and the degree of orientation of the filamentous polymer discharged from the die hole It is a parameter that influences. If the die discharge linear velocity is low, the ratio of the die discharge linear velocity to the take-off roller 6 is increased when the take-up roller 6 takes the wire, and an excessive drawing tension is applied to the filament being drawn, resulting in a single yarn breakage and stability. It cannot be prevented. On the other hand, if the die discharge linear velocity is too high, the fiber orientation after taking up by the take-up roller 6 and then drawing by the drawing roller 7 is excessively advanced, resulting in a fiber having a low moisture absorption rate.
- the spinning conditions are such that the product of the take-up speed (m / min) of the yarn taken up by the take-up roller 6 and the draw ratio which is the value of the peripheral speed ratio of the take-up roller 6 and the draw roller 7 is 3900 or more and 4500. Is set.
- This numerical value represents the total amount of stretching of the polymer discharged from the die from the die discharge linear speed to the circumferential speed of the take-up roller 6, and further from the circumferential speed of the take-up roller 6 to the circumferential speed of the drawing roller 7. If this value is too small, the degree of orientation of the fiber is low and the moisture absorption rate becomes too high, and the spinning oil and moisture in the air are excessively absorbed. As a result, the yarn swells and stable spinning cannot be performed. On the other hand, if this value is too large, the orientation of the fiber proceeds too much, resulting in a fiber having a low moisture absorption rate.
- the spinning oil applied by the oil supply device 4 is a non-hydrous oil.
- a non-hydrous oil agent is applied, there is no possibility that moisture is absorbed by the polyamide 56 during the oil agent application, so that so-called polyamide swelling does not occur, and therefore there is no fiber length variation during yarn production, and stable winding. Is possible.

It is processed after weaving and weaving by a normal method, and can be sewn to make various clothing products such as innerwear, pantyhose and tights.

1m/周の検尺機で10回転させて、10ターンのループ状かせを5個作成し、重量測定用の試料とする。また同様にして10ターンのループ状かせを作成し、該かせの糸端同士を結んでほどけないようにしたループ状かせを5個作成し、試料長測定用の試料とする。まず計10個の試料を25℃RH55%の環境下、無荷重の状態で48時間放置して調湿した。その後同環境下にて、重量測定用のループ状かせの重量を測定して平均値A(g)を求めた。次に同様に同環境下にて試料長測定用ループ状かせのかせ長を測定した。試料長測定用のループ状かせをフックにかけ、ループ状かせに0.05cN/dtex相当の荷重をかけてかせ長を測定した。荷重を決定する際には試料の見掛繊度(=A(g)×10,000/10)を用いた。かせ長の20倍が試料長となり、5個の試料長の平均値B(m)を求めた。そしてAをBで除した後、10,000倍することにより総繊度を求めた。単繊維繊度は上記総繊度をフィラメント数で除して求めた。
G.モールド加工性
直径15cmにくりぬいた厚さ2cmの固定具2枚の間にたるみ無く、リラックスさせた状態で伸縮性布帛を固定し、表面温度200℃に加熱した直径10cmの半球状の熱鉄球を布帛に押し込み、深さが10cmとなるように押し当て60秒後直ちに熱鉄球を抜き取る。整形されたこぶ状部表面形態について、加工前後での外観を以下基準で評価する。
H.吸水性ストレッチ編地の着用評価
実施例1および比較例1、比較例5、比較例7の糸を用いてそれぞれ編地を編成し、体にフィットするように縫製したTシャツのサンプルを作製し、25℃×65%RHの室内で5名の被験者がこれらのTシャツを着用した状態で時速12Kmのジョギング運動を5分間行った後、被験者の自己申告で発汗時のべとつき感を次の評価基準に基づいて比較評価した。
良:べとつき感なし
可:べとつき感があるが、我慢できる
不可:べとつき感があり不快。
