Description of the invention (1) TECHNICAL FIELD The present invention relates to a polyester fiber and a manufacturing method thereof, more specifically, a polyester fiber and a polyester fiber used in the raw yarn for processing and processing of the raw silk, L. law. Xinwan Background Technology Among the poly-fibers used in the Jane II H-defense and defense yarns, semi-oriented yarns (partially oriented yarns) are widely used. The polyester semi-stretched yarn is obtained by spinning molten polyester from a spinning tube, and pulling the spinning yarn at a high speed of more than 300 m / min = while cooling and solidifying with cooling air. Can be manufactured. &amp; The polyester semi-stretched yarn obtained by such two-speed spinning and drawing had a breaking elongation of 38 and a birefringence ^ of 0.0. Below 7, the proportion is not full! Physical property value of .35g / cm. In the past, this polyester semi-stretched yarn was used as the representative variety hd-36i (83dtx-36f) of the original false-twisted processing stretch-twisted yarn, and the processing speed was 900-1000 m / min. , The processing tension of 40-50c + N ^ conditions for extended false twist processing, to obtain a residual elongation of about 20-25%, the residual elongation of this type of shirt loose processing yarn because the higher to about 20 -2 5 % Range, so even if used in high-order projects of weaving engineering and knitting engineering, wire breakage does not occur and stable operations can be performed. However, for the purpose of further improving productivity, the extension false twist processing speed is increased to 120 m / min or more, and the processing tension is increased to 55 or more in order to stabilize the tension during high-speed processing. The polyester semi-stretched yarn with the above-mentioned physical property value is used as the raw yarn for the stretch false twist processing, and only the bulk processing freshness with a residual elongation of less than 20% is obtained. Because of the residue of bulk processing silk

本發明之聚S旨纖維為雙折射△ η為〇. 〇 7以上、斷裂伸度 為8 0 %以上，且比重為1 · 3 5 g / c m3以上為其特徵。即，先前 之聚酿半延伸絲雖於複折射率△ η和斷裂伸度為大約相同 之物性值，但因比重為未滿1 · 3 5 g / c m3，故比先前者於纖維 内分子之結晶化度更高，且具有大的抗張力。 因此，例如於延伸假捻加工絲之代表品種 7 5d-36 f( 83d tx-36 f之）情形中，即使令延伸假捻加工速度 提高至先前一般的100〇m/min至1200m/min以上，且令加工 張力由49cN左右之程度提高至55cN以上，亦不會發生斷絲 且可保證安定的延伸假捻加工，並且可令所得膨鬆加工絲 之殘留伸度為2 0 %以上，特別為2 〇〜2 5 %之程度。The polyS fibers of the present invention are characterized by a birefringence Δη of 0.07 or more, an elongation at break of 80% or more, and a specific gravity of 1.35 g / cm3 or more. That is to say, although the previously polymerized semi-stretched yarns have approximately the same physical properties in terms of complex refractive index Δη and elongation at break, the specific gravity is less than 1.35 g / c m3. It has a higher degree of crystallization and has a large tensile strength. Therefore, for example, in the case of 7 5d-36 f (83d tx-36 f), the representative variety of extended false twisted yarn, even if the extension false twisted processing speed is increased to 100 m / min to 1200 m / min or more , And the processing tension is increased from about 49cN to more than 55cN, no breakage will occur and stable extension false twist processing can be guaranteed, and the residual elongation of the resulting bulked processing yarn can be more than 20%, especially It is about 2 to 25%.

如此經由延伸假捻加工速度之高速化而提高生產性，又 經由高張力化抑制張力變動，故可取得高品質的膨鬆加工 絲。更且，因為經由延伸假捻加工所得之膨鬆加工絲的殘 留伸度大，故即使供於織布工程和編織工程之高次工程亦 不會發生斷絲，可進行安定之作業，且可令織布和編織所得 之織編物作成而品質。In this way, productivity is improved by increasing the speed of the stretch false twist processing speed, and tension variation is suppressed by increasing the tension, so that a high-quality bulky yarn can be obtained. In addition, since the residual elongation of the bulky processing yarn obtained through the extended false twist processing is large, even if it is used in the high-order process of the weaving process and the knitting process, the wire break does not occur, and stable operations can be performed, and Weaving and weaving woven fabrics are made and quality.

Description of the Invention (16) As mentioned above, if the polyester fiber according to the present invention has a specific gravity of 1. 3 5 g / c m3 or more, even if the crystallization of the molecules in the fiber, the extension false twist processing speed is increased, and the processing tension is increased, it also has the anti-tension that does not break the yarn. In addition, because the specific gravity is high and the birefringence Δη is 0.07 or less, and the elongation at break is 80% or more, the residual elongation of the bulked yarn after the extended false twist processing can be made to be 20% or more. . Therefore, even if the bulk processing yarn is supplied to higher-order processes such as weaving process and knitting process, the yarn breakage does not occur, and the operation can be stabilized. In addition, since the yarn is not broken in high-level processes, a high-quality knitted fabric can be obtained.

568963 _ 案號 90124fUzl568963 _ Case No. 90124fUzl ^ 一種聚酿纖維假捻加工絲之製造方法，其特徵為： 六、申請專利範圍 _ 管嘴所咖出之 =产:下^ r 又 人由刖述牽引輥以捲取裝置捲取成捲裝 (Package)為止之間，於高於玻璃轉移溫度之溫度中加埶 =得雙折射Δη為0·07以下、斷裂伸度為8〇%〜14〇%、比 ^ 1 · 35〜1 · 377g/cm3之物性值的高順向未延伸聚醋纖維， 。人―將該高順向未延伸聚酯纖維作為延伸假捻加工用原 絲，藉由對之以速度12〇〇m/min以上、張力55州以上進行延 伸假捻加工，以形成殘留伸度為2〇〜26· 5%的膨鬆加工絲。 2 ·如申請專f範圍第丨項之聚酯纖維假捻加工絲之製造 方法，其中，由前述熔融紡出之聚酯絲條之單側吹送冷卻風 予以冷卻，並且令前述牽引輥之拉引速度為 3000〜4500m/min 。 3 ·如申請專利範圍第1項之聚酯纖維假捻加工絲之製造 方法，其中，由前述溶融紡出之聚酯絲條之全周圍吹送冷卻 風予以冷卻，再於下游側令冷卻風於平行於行走方向上流 動且賦與應力緩和，一邊令前述牵引輥之拉引速度為 3000〜5000m/min 〇^ A method for manufacturing false-twisted processing yarn of poly-brewed fiber, which is characterized by: 6. Scope of patent application _ Out of the nozzle = production: down ^ r The reel is wound into a roll by a retraction device Before the installation (Package), add 埶 at a temperature higher than the glass transition temperature to obtain a birefringence Δη of 0.07 or less, an elongation at break of 80% to 14%, and a ratio of ^ 1 · 35 to 1 · High forward unstretched polyester fiber with a physical property value of 377g / cm3. Man-This high-direction non-stretched polyester fiber is used as the raw yarn for false-twist processing. The false-twist processing is performed at a speed of 12,000 m / min and a tension of 55 states to form a residual elongation. It is 20 ~ 26 · 5% bulked yarn. 2 · If the method for manufacturing a polyester fiber false twisted processing yarn according to item 丨 of the special application is applied, wherein the cooling side is cooled by blowing cooling air from one side of the polyester yarn melt-spun, and the pulling of the traction roller is performed The speed is 3000 ~ 4500m / min. 3. The manufacturing method of polyester fiber false-twisted processing yarn according to item 1 of the patent application scope, wherein the entire circumference of the polyester yarn produced by the melt spinning is blown with cooling air for cooling, and then the cooling wind is applied to the downstream side. Flow parallel to the direction of travel and relieve stress, while setting the pulling speed of the traction roller to 3000 ~ 5000m / min.
