- the melt spinning temperature is not limited as long as the false twisted polyamide mixed composite yarn of the present invention can be obtained, and is usually used, for example, 240 to 260 ° C. in the case of polycaproamide, polyhexamethylene adipamide. 275 to 295 ° C. is preferably used in this case, but when the same die is used, the viscosity at the time of melt spinning is high (for example, when the melt spinning temperature is low or the viscosity of polyamide is high) and the degree of globalization LB Increases, and the viscosity tends to decrease when the viscosity is low (for example, when the melt spinning temperature is high or when the viscosity of the polyamide is low).
- the production method of the false-twisted polyamide mixed composite yarn of the present invention is not particularly limited, but the polyamide is melted, discharged from the die, cooled by blowing cooling air, and converged (that is, an oil agent). From the viewpoint of cost, a one-step method in which an interlace nozzle is applied and wound on a package is preferable.
- the elongation of the false twist polyamide fiber of the present invention is preferably 45 to 70%. If the elongation is too low, the tensile resistance of the filament is increased, and the actual number of twists that are twisted in the false twisting process is reduced, so that it is difficult to impart sufficient crimp to the obtained processed yarn. In yarn, yarn breakage and fluff are likely to occur, and high-order passability tends to be inferior. On the other hand, if the elongation is too high, the actual number of twists to be twisted becomes excessive, fluffing occurs in the obtained processed yarn, the strength tends to decrease, and the drawn yarn has a high residual elongation.

On the other hand, if the stress at 15% elongation is too high, a large tension is concentrated on the interlace part when false twisting is performed, causing breakage of the single yarn, which tends to deteriorate the process passability and the quality of the woven or knitted fabric. The measurement of the stress when the 15% elongation is performed is based on the method described later.
- the polyamide mixed composite yarn for false twisting of the present invention is wound once, and then transported to the false twisting step, which is the next step, and is subjected to crimping to make a false twisted yarn into a knitted or woven fabric.

At this time, the stretching simultaneous false twisting is performed using a friction false twisting tool or the like. Furthermore, the crimpability may be lowered by using a second heater (2HT). In this case, 2HT may be a contact type or a non-contact type, but the second heater temperature is suitably 120 to 220 ° C., preferably 140 to 190 ° C. Thereafter, an oil agent of about 1.0 to 3.0% with respect to the weight of the false twisted yarn is applied. Moreover, you may provide an interlace in order to improve the convergence of a process yarn before and after oil agent provision.

また、従来の混繊複合糸として、例えば、少なくとも2種類以上の異なる断面形状の単フィラメントが分散した混繊糸が知られている(特許文献2)。
一方、単糸細繊度異形断面ポリアミドマルチフィラメントとして、例えば、単糸繊度が0.99dtexの同数の六葉/丸断面ポリアミドマルチフィラメントが知られている(特許文献3)。
好ましい混繊状態は図2に見られるごときものであって、それぞれの断面形状の単フィラメントがブロック状の群をなした状態でなく断面形状に区別なく適度に分散していることで仮撚りを施したとき、糸の表面においてそれぞれの断面形状が分散配置しやすくなるので、凹部を有する断面と凹部を有しない断面との調和した複合効果によるサラサラな風合とマイルドな光沢をより効果的に得ることができる。なお、図2は、本発明の仮撚用ポリアミド混繊複合糸における好ましいフィラメントの分散状態を示す一例である。
また、本発明の混繊複合糸は、凹部を有しない断面形状のフィラメントの少なくとも1種類と、前記凹部を有する断面形状のフィラメントの少なくとも1種類とが、接触した場合に該それらのフィラメント断面間に空隙を形成することのできる断面形状であるフィラメントを含むことが好ましい。
実施例中の各特性値は次の方法にしたがって求めた。
サンプル5gを精秤して磁性ルツボに入れ、電気炉を用いて1000℃で灰化し、灼熱残分を酸化チタンとして重量%で表した。
試料を秤量し、98重量%濃硫酸に試料濃度(C)が1g/100mlとなるように溶解し、該溶液についてオストワルド粘度計にて25℃での落下秒数(T1)を測定する。さらに試料を溶解していない98重量%濃硫酸について、同様に25℃での落下秒数(T2)を測定した後、試料の相対粘度(ηr)を下式により算出する。
(ηr)=(T1/T2)+{1.891×(1.000-C)}。
試料を枠周1.125mの検尺機にて27デシテックス以下の品種は400回巻、28デシテックス以上の品種は200回巻カセを作成(n数:4)し、熱風乾燥機にて乾燥後(105±2℃×60分)天秤にてカセ重量を量り公定水分率を乗じた値から総繊度を算出した。4回測定を行い、算出された繊度を平均して繊度とした。また、少なくとも2種類の異なる断面形状のフィラメントにおける単糸繊度については、以下に示す式にて、それぞれの断面形状におけるフィラメント断面の合計面積の面積比を算出し、上記総繊度に面積比を乗じ、同形状のフィラメントの総数で割った値とした。また、それぞれの断面形状におけるフィラメント断面の合計面積の面積比を混繊比率とした。
断面Aの面積比=断面Aの面積/(断面Aの面積+断面Bの面積)
断面Bの面積比=断面Bの面積/(断面Aの面積+断面Bの面積)
混繊フィラメント中の断面Aの単糸繊度(dtex)=(総繊度(dtex)×断面Aの面積比)/断面Aのフィラメント数
混繊フィラメント中の断面Bの単糸繊度(dtex)=(総繊度(dtex)×断面Bの面積比)/断面Bのフィラメント数。
