In view of the above problems, the present invention provides the following inventions.
That is, the present invention is a fiber comprising a polyester resin, the polyester resin is a copolymer polyester comprising a dicarboxylic acid component and a glycol component, and 80 mol% or more of the dicarboxylic acid component is terephthalic acid and / or an ester-forming derivative thereof, and from 4.0 to 12.0 mol% is cyclohexane dicarboxylic acid and / or an ester-forming derivative thereof, and 2.0 to 8.0 mol%, and aliphatic dicarboxylic acids An ester-forming derivative, wherein the glycol component is a polyester fiber mainly composed of ethylene glycol and / or an ester-forming derivative thereof, and preferably the aliphatic dicarboxylic acid in the polyester resin is sebacic acid or decanedicarboxylic acid It is said polyester fiber which is.
次に、本発明のポリエステル樹脂は、例えば単軸押出機や二軸押出機を用いて溶融混練
する。溶融混練する際の温度は、シクロヘキサンジカルボン酸及び脂肪族ジカルボン酸の
共重合量によって異なるが、斑なく安定に溶融混練し且つ安定な製糸性や品位を得るため
には、ポリマーの融点から３０〜６０℃高い温度範囲で溶融押出するのが好ましく、２０
〜５０℃高い温度範囲とすることがより好ましい。
更に、混練設備を通過してから紡糸頭に至るまでの間の溶融温度についても、シクロヘ
キサンジカルボン酸及び脂肪族ジカルボン酸の共重合量によって異なるため一概に特定は
できないが、溶融斑なく安定な状態で紡出させ、且つ安定な製糸性や品位を得るためには
、ポリマーの融点から３０〜６０℃高い温度範囲で溶融押出するのが好ましく、２０〜５
０℃高い温度範囲とすることがより好ましい。
Next, the polyester resin of the present invention is melt kneaded using, for example, a single screw extruder or a twin screw extruder. Temperature during the melt-kneading varies depending copolymerization amount of cyclohexane dicarboxylic acid and aliphatic dicarboxylic acids, in order to obtain a plaque without stable melt kneading and stable spinnability and quality from the melting point of the polymer 30 It is preferable to melt extrude in a temperature range higher than -60 ° C, 20
More preferably, the temperature range is higher by -50 ° C.
Furthermore, the melting temperature from passing through the kneading equipment until reaching the spinning head also cannot be specified because it differs depending on the copolymerization amount of cyclohexanedicarboxylic acid and aliphatic dicarboxylic acid, but it is stable without melting spots. In order to obtain a stable spinning property and quality, it is preferable to perform melt extrusion at a temperature range 30 to 60 ° C. higher than the melting point of the polymer.
More preferably, the temperature range is higher by 0 ° C.
