ル特殊糸の製造方法に関する。Detailed Description of the Invention (Industrial Field of Application) The present invention is a special polyester material having irregular strength and elongation properties, heat absorption properties, dyeing properties, uneven thickness, etc. in the length direction of +Jt fibers. This invention relates to a method for manufacturing yarn.

て劣っている。Because it has chemical properties, it is used in a wide range of applications, including clothing and industrial materials. However, when used for clothing, polyester fibers have a slimy, waxy, and waxy feel.
Due to its coldness, it is extremely inferior to natural #a fiber in terms of texture.

面を有するポリエステル長繊維太細糸条が提案されてい
る。Therefore, various approaches have been taken to solve these disadvantages peculiar to polyester fibers and to obtain polyester fibers with a texture superior to that of natural m-fibers and a shading effect due to the difference in dyeability. In addition, research has been carried out on threads with intermittent parts of different thickness in the fiber axis direction, and recently, Japanese Patent Application Laid-Open No. 5,5-80524 has developed yarns with diameter changes in the d-axis direction and thicker parts. There is a difference in dyeing in the thin parts,
Furthermore, a polyester long fiber thick and thin yarn has been proposed in which the thick portions that exist partially intermittently have a curved deformed cross section.

ことを指摘している。Moreover, conventional methods for obtaining such yarns include supplying two or more types of yarns using a design twisting machine, a twisting machine, a false twisting machine, etc., and setting a feed rate difference between the yarns. It is also possible to make heathered threads and marbled threads by supplying two or more types of threads with different dyeability or threads dyed in different colors in advance and using similar means and methods. , it has been pointed out that all of these methods have high manufacturing costs and are severely restricted in terms of manufacturing equipment.

、アルカリ処理に耐え得る適正条件の組み合せを考慮し
なければならず、なお、製造上の問題を含んでいる。Therefore, some embrittlement of the polyester yarn is inevitable, and in particular, it is necessary to consider the combination of appropriate conditions that can withstand the alkali treatment, which also involves manufacturing problems.

糸条を得る。If the diameter of the circular spinning hole is outside the range of 0.1θ to 0.80 mm and is less than 0.10, polymer clogging occurs frequently at the spinneret, making spinning difficult; if it exceeds o or ao, spinning becomes difficult. The draft becomes too high and uneven discharge occurs, which causes uneven fineness in the longitudinal direction of the yarn and increases the number of yarn breakages. or,
The diameter of the circle forming the circumference arranging the four circular spinning holes is 0.32 mm.In the case of no groove, all the spun polymers are fused and a U-shaped cross-section fiber cannot be obtained;
If it exceeds 100%, conversely fusion occurs and the desired U-shaped cross-section fiber cannot be obtained. Furthermore, as shown in FIG.
The angle formed by the center of the circumference of mm and the centers of two mutually adjacent circular spinning holes I is '1 sα2. It is preferable that a8 and α4 are arranged so as to fully satisfy the following formulas (1) to (4)0 60″≦α1≦85@ ・・・・・・・・・ (1

(4) (However, α1 * "2 *" 8 and α4 are arranged in this order, and the maximum angle 'k (1 m).) After melt spinning the polyester filament, it is The spun filaments spun through the circular spinning hole I are fused to obtain a yarn having a substantially U-shaped cross section.

、このロー２の下流に延伸ロー２を設置した装置が設備
的にコンパクトで製造上有利である。The polyester filament yarn having a U-shaped cross section as described above is subsequently subjected to a drawing treatment without being wound up. Any direct stretching method can be adopted for the stretching process, but usually a device with a roller that serves as a take-up roller and a preheating supply row 2 under the spinneret and a stretching row 2 installed downstream of this row 2 is the most efficient. It is compact and advantageous in manufacturing.

てワンダー７に捲取られる。The yarn Y spun by the spinning device 1 is applied with oil by the oiling roller 2, wound several times around the take-off roller 8 preheated to the drawing temperature via a separate row 24t, and taken off at a predetermined speed. At the same time, it is preheated to a stretching temperature, and after being stretched to a predetermined magnification by the next stretching row 26, interlacing is applied by an interlacing treatment nozzle 6 as required, and the film is wound up into a wonder 7.

変化し易くなる。In the present invention, the surface speed of the take-up row 28 at this time is 1000 to 20002F! / minute. When the take-up speed increases to 2000 m/min, the contrast between the thick and thin portions of the resulting yarn Y becomes insufficient. Also,
When the take-up speed is less than 1000 m/min, productivity decreases and furthermore, the obtained thick and thin yarn tends to change over time.

-75°C, preferably 60-75°C, more preferably 6
Stretching is performed by heating at a temperature of 5 to 75°C. Heating temperature is 50
If the temperature is lower than 0.9°C, stretching becomes extremely uneven during stretching, resulting in a large number of loose filaments, and single filament breakage occurs when winding up the cheese, unwinding it, and performing weaving and weaving.

による糸切れを防ぐことが出来好ましい。In the case of polyester filament yarn with a U-shaped cross section as in the present invention, it is a special yarn that maintains a good appearance and feel even when heated at temperatures of 50°C or 60°C or higher, and also suppresses sagging of the filament. This is preferable because it can prevent thread breakage due to cheese unrolling and fuzz generation.

が低下する。The stretching ratio of the present invention varies depending on the above-mentioned take-up speed,
When the take-up speed is t-y8 (m, 4) and the stretching ratio is DR (times), the following formula (%) must be satisfied. If the stretching ratio is lower than the above range, the strength required for clothing cannot be obtained, and loose filaments cause severe targing, resulting in poor operational performance in subsequent processes.
延伸倍率が前記範囲よシ高いと繊維の長手方向及び愼維
相互間の繊度むらが少なく、濃淡効果の発現が極めて弱
い。If the stretching ratio is higher than the above range, there will be little unevenness in fineness in the longitudinal direction of the fibers and between the fibers, and the shading effect will be extremely weak.
又、本発明のＵ字型断面を有するイ、Ｒ惟では単に延伸
条件を変更するのみで染色性に変化のある繊維が、製造
可能となり冷延伸の必要は全くない。Further, in the case of the A-R fiber having a U-shaped cross section of the present invention, it is possible to produce fibers with varying dyeability by simply changing the stretching conditions, and there is no need for cold stretching.

た後型糸切れが発生する傾向をもつ。That is, by applying sufficient heat, the structure of the fiber itself becomes very stable, making it very easy to handle the fiber in subsequent steps. In particular, the ability to obtain fibers that can be processed for weight loss has expanded the scope of use.To describe specifically the unique shape of special yarns made of industrial fibers, the filaments have uneven thickness in the longitudinal direction. However, the thick cross section of the filament is within a range of 1.20 to 8.00 times the area ratio of the thin cross section, and the number of filaments having a thick cross section is 80% or less of the total, preferably 70% or less. , furthermore, when the length of the part with uneven thickness is 0.5 to 5 cm, plO per 1 m
It is a special polyester thread having ~80 pieces. in this case,
If the cross-sectional area of the thick filament is less than 1.20 times, the shading effect will be weak, and if the cross-sectional area of the thick filament is more than 3 times that of the thin filament, the single fiber strength of the thick filament will be extremely low, and it will be There is a tendency for thread breakage to occur after the product is made.

If it is 0 cm or more, the darkly dyed part will be too noticeable and the quality will deteriorate. Also, if the number is less than 10, the dyeing difference will be weak, and if it is more than 80, it will become too strong.
