본 발명은 상연(上撚)과 하연(下撚)의 꼬임 방향에 관계없이 균일한 품질특성을 갖는 단섬유인 방적사와 필라멘트사의 합연복합사의 제조방법에 관한 것으로, 좀 더 구체적으로는 단섬유인 방적사와 장섬유인 필라멘트사를 합연하여 복합사를 제조함에 있어서, 방적사와 합연사의 연방향 및 연수와 사용하는 방적사의 굵기에 따라 필라멘트사의 공급장력을 항상 일정수준으로 조절하므로서 합연시 방적사와 필라멘트사의 장력차이를 없애주어 균일한 품질특성을 갖는 합연복합사를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a spun yarn of filament yarn and filament yarn composite yarns having uniform quality characteristics regardless of the twisting direction of the upper and lower edges, more specifically In manufacturing composite yarn by combining filament yarn, which is spun yarn and long fiber, spun yarn and filament at the time of jointing by controlling the supply tension of filament yarn at a constant level according to the direction of yarn and soft yarn and the number of spun yarn used. The present invention relates to a method for manufacturing a composite composite yarn having uniform quality characteristics by removing the tension difference between the yarns.

복합사는 이종섬유를 방사 단계에서 또는 방사후 가공단계에서 서로 혼합하여 새로운 특성과 효과를 갖도록 한 실을 의미하는 것으로, 각각의 섬유에서 나타나는 단점들을 극복할 수 있기에 많이 사용되고 있는 추세이다.Composite yarn refers to a yarn that is mixed with each other in the spinning step or post-spinning processing step to have new properties and effects, it is a trend that is used a lot to overcome the disadvantages of each fiber.

특히, 면사, 모사, 견방사, 마사등과 같은 천연섬유 방적사와 합성섬유 필라멘트사를 혼합하여 제조한 합연복합사가 광범위하게 사용되고 있다. 그러나, 방적사와 합성섬유필라멘트사로 합연복합사를 제조하는 경우 합연공정을 행하게 되면 방적사는 연축이 일어나게 된다.In particular, a joint composite yarn prepared by mixing natural fiber spun yarn such as cotton yarn, wool yarn, silk yarn, and yarn and synthetic fiber filament yarn is widely used. However, when the jointed composite yarn is manufactured from the spun yarn and the synthetic fiber filament yarn, the spun yarn is stretched when the jointing process is performed.

종래에 방적사와 필라멘트사로 된 복합섬유를 제조할 경우, 합연시 방적사는 연축이 일어나게 되므로 방적사와 합성섬유 필라멘트사의 장력차이가 발생하여 제조되는 복합사의 품질특성이 균일하지 못한 단점이 있었다.Conventionally, when manufacturing the composite fiber made of yarn and filament yarn, the spun yarn is spun when combined, there is a disadvantage that the quality characteristics of the composite yarn produced by the tension difference between the yarn and synthetic fiber filament yarn occurs.

따라서, 본 발명의 목적은 상연과 하연의 연방향에 관계없이 균일한 품질특성을 갖는 장단복합사의 제조방법을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a method for producing a long and short composite yarn having uniform quality characteristics regardless of the longitudinal direction of the upper and lower edges.

상기 목적뿐만아니라 용이하게 표출될 수 있는 또 다른 목적달성을 위하여 본 발명에서는 단섬유인 방적사와 장섬유인 필라멘트사를 합연함에 있어서, 방적사와 합연사의 연방향 및 연수와 사용하는 방적사의 굵기에 따라 필라멘트사의 공급장력을 조절함으로서 합연시 방적사와 필라멘트사의 장력차이를 업애 균일한 품질특성을 갖는 합연복합사를 얻을 수 있다.In order to achieve the above object as well as another object that can be easily expressed in the present invention in combining the filament yarn of the short fiber and filament of filament, the yarn direction and the number of yarns and the number of spun yarn used Accordingly, by controlling the supply tension of filament yarns, it is possible to obtain a jointed composite yarn having uniform quality characteristics by improving the tension difference between the spun yarn and filament yarns during jointing.

이하, 본 발명를 구제적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

일정방향으로 꼬임을 준 단섬유 방적사와 꼬임이 없는 장섬유 필라멘트사를 합연하여 방적사의 장점과 필라멘트사의 장점을 동시에 갖는 합연복합사를 제조함에 있어서, 방적사의 굴기와 합연사의 연수 및 연방향에 필라멘트사의 오버 피이드율(over feed ratio)을 연산하여 이 오버 피이드율에 의해 필라멘트사의 송출량을 조절함으로써 장력이 균일한 합연복합사를 얻을 수 있다.In manufacturing a composite composite yarn having both the advantages of spun yarn and filament yarn by combining short fiber spun yarn twisted in a certain direction and long fiber filament yarn without twist, By calculating the over feed ratio of the filament yarn and adjusting the feeding amount of the filament yarn by this overfeed ratio, a jointed composite yarn with uniform tension can be obtained.

제1도는 실에 꼬임(TWIST)을 줄때 실의 단면 직경과 1피치(pitch)의 트위스트에 상당하는 원주표면길이를 나타내는 도면으로서, 방적사의 트위스트가 Z방향이고 연수가 K인 경우, 방적사의 단면직경(d)과 1피치의 트위스트에 상당하는 사장(h)과 원주표면길이(ℓ)는 다음과 같다.1 is a diagram showing the circumferential surface length corresponding to a twist of the cross section diameter and one pitch when twisting the yarn. When the twist of the yarn is in the Z direction and the number of years is K, the cross section of the yarn The yarn length (h) and the circumferential surface length (L) corresponding to a diameter (d) and a twist of one pitch are as follows.

여기서 p는 섬유의 비중, Nm은 실의 공통식 번수이다.Where p is the specific gravity of the fiber and Nm is the common number of yarns.

여기서 D는 방적사의 단면원주로서 πd이다.Where D is πd as the cross circumference of the yarn.

위에서와 같이 트위스트에 의해서 단면직경과 1피치당 트위스에 상당하는 원주표면길이가 달라지는 방적사를 필라멘트사와 함께 합연하는 경우, 방적사 고유의 연수 및 연방향은 상연의 연수 및 연방향에 의하여 영향을 받게 된다.When combining yarns with filament yarns whose cross section diameter and circumferential surface length corresponding to twists per pitch are changed by twist as described above, the inherent softening and softening direction of the spun yarn is affected by the softening and softening direction .

즉 상연과 하연이 같은 방향인 경우 합연사의 연수는 상연의 연수와 하연의 연수 합계가 되므로 이 경우 합연사는 연축 현상이 일어나 합연사의 길이는 짧아지며 굵기는 그 만큼 굵어지게 되며 또 상연과 하연이 서로 반대방향인 경우 합연사의 연수는 상연과 하연의 연수 차이 만큼 줄어들게 되므로 오히려 방적사의 꼬임은 풀어지고 합연사의 길이는 길어지면서 굵기는 가늘어지게 된다.In other words, if the upper and lower edges are in the same direction, the number of trains of the twisted and twisted yarns is the sum of the number of years between the upper and lower stations. In the opposite direction, the training of the twisted yarn is reduced by the difference between the upper and lower stations, so the twist of the yarn is loosened and the length of the twisted yarn becomes longer and the thickness becomes thinner.

이와같이 합연시 연방향과 연수에 따라 방적사의 길이는 길어지기도 하고 짧아지기도 할 뿐 아니라 트위스트 1피치당 원주표면길이가 늘어나거나 줄어들게 되므로 합연사 제조시 필라멘트사의 오버 피이드율을 사전에 연산하여 이 오버 피이드율에 의해 필라멘트사의 송출량을 조절하여 얻어진 합연사의 필라멘트 장력 차이를 없애도록 한 것이다.In this way, the yarn length becomes longer and shorter depending on the direction and the number of years when joining, and the circumferential surface length per pitch is increased or decreased, so the overfeed rate of filament yarn is calculated beforehand. By controlling the amount of filament yarn discharged by the rate, the filament tension difference of the twisted yarn obtained is eliminated.

즉, 제2도에 도시된 바와같이 합연공정에서 필라멘트사는 장력조절장치(3)과 드럼(5) 사이에 연산장치(6)와 피이드로울러(4)를 설치하여 방적사의 연수, 번수 및 연방향에 의하여 필라멘트사의 오버 피이드율을 사전에 연산하고 이 오버 피이드율을 조절해 줄 수 있는 피이드 로울러(4)에 의하여 필라멘트사의 송출량을 조절함으로서 완성된 합연사는 균일한 장력을 유지할 수 있게 된다. 이 장력 조절장치(3)는 실에 일정한 권취장력을 가함으로써 실을 감을때 어느 정도 단단하게 감을 수 있게 해 준다.That is, as shown in FIG. 2, in the joining process, the filament yarn is installed between the tension control device 3 and the drum 5, and the arithmetic unit 6 and the feed roller 4 are used for the number, the number, and the direction of the yarn. By controlling the feed amount of the filament yarn by the feed roller (4) that can calculate the over-feed rate of the filament yarn in advance and can adjust the over-feed rate, the finished twisted yarn can maintain a uniform tension. This tension adjusting device 3 allows the coil to be wound to some extent when winding the thread by applying a constant winding tension to the thread.

이하, 본 발명은 실시예에 의해 구체적으로 설명한다.Hereinafter, the present invention will be specifically described by way of examples.

[실시예]EXAMPLE

연방향이 Z방향이고, 연수가 800TPM인 30수 단사의 레이욘 단섬유 방적사(비중:1.50)를 50d/36f의 폴리에스테르 필라멘트사와 합연복합함에 있어서, 레이욘 단섬유 방적사의 단면직경(d)은 상기 식(1)에 의하여Federal flavor and Z direction, the training is 800TPM 30 can be a single shot of a rayon short fiber yarn (weight: 150) in as a 50d / 36f polyester filaments Inc. plied composite, rayon end cross-section diameter of the fiber yarn (d ) Is obtained by the above formula (1).

(레이욘 단섬유 방적사의 섬도인 영국식 번수(Ne) 30'S를 미터식 번수(Nm)로 환산하면 50.76'S임)(Even 30 ' S , the fineness of Rayon's short-fiber yarn, is 50.76' S in terms of metric number (Nm))

따라서, 레이욘 단섬유 방적사의 단면 원주(dπ)는 0.40621mm가 된다. 즉 제1도에 도시된 단면직경(d)는 0.1293mm이고, 원주(dπ)는 0.40621mm이며, 트위스트 1피치에 상당하는 실이 길이(h)는 1,000÷800=1.25mm가 되므로 트위스트 1피치에 상당하는 원주표면길이(l)는 피타고라스의 법칙에 따라 계산하면,가 된다.Therefore, the cross sectional circumference d pi of the rayon short fiber spun yarn becomes 0.40621 mm. That is, the cross-sectional diameter (d) shown in FIG. 1 is 0.1293 mm, the circumference (dπ) is 0.40621 mm, and the thread length corresponding to the twist 1 pitch (h) becomes 1,000 ÷ 800 = 1.25mm, so that the twist 1 pitch The circumferential surface length (l) corresponding to is calculated according to Pythagorean law, Becomes

이 레이욘 단섬유 방적사와 폴리에스테르 필라멘트사를 Z800TPM의 꼬임을 주어 합연한다고 가정하면, 단섬유 방적사는 하연인 Z방향 800TPM과 상연인 Z방향 800TPM이 합쳐져 결과적으로 방적사는 Z방향, 1600TPM의 꼬임이 형성되고 이와같은 꼬임의 증가로 인하여 사장은 짧아지게 된다. 이경우 사장이 짧아지는 율은 Z방향 꼬임이 추가로 800TPM 들어갈때 꼬임에 의한 길이방향 연축(β)은 아래와 같이 계산할 수 있다.Assuming that Rayon short-fiber yarn and polyester filament yarn are joined by twisting Z800TPM, short-fiber yarn is combined with lower Z-direction 800TPM and upper-direction Z-direction 800TPM. And the twist is shortened due to this increase in twist. In this case, the rate of shortening of the dead thread is calculated as follows when the longitudinal twist (β) due to twist when Z twist is additionally 800 TPM.

연계수에서,Linkage in,

TPI는 1 inch의 실에 꼬임이 들어간 회수를 나타내는 단위이므로 800TPM을 1 inch당 꼬임수 즉 TPI로 환산하면 20.32TPI가 된다.TPI is because when converted to 800TPM unit indicating the number of times of the twist into the chamber of 1 inch to 1, i.e. TPI is twists per inch is 20. 32 TPI.

따라서이 되고, 이 경우 연축(β) = 2.64×Tα - 4.82이므로 결과적으로 연축(β)은 4.975%가 된다. 결론적으로 Z 800TPM의 상연을 줄때에 연축(β)이 4.975% 만큼 발생한다.therefore In this case, the spasms (β) = 2.64 x Tα-4. 82 , and as a result, the spasms (β) are 4.975%. In conclusion, when the staging of Z 800 TPM occurs, spasm (β) occurs by 4.975%.

따라서 1,000mm의 사가 49.75mm 만큼 줄어드는 결과가 되므로 1,000mm의 사는 950.25mm의 사가 되고 번수도 변하여 사의 직경도 변하게 되다.Thus the 1,000mm Saga 49. Since the result reduced by 75 mm may be changed once to live of 1,000mm Saga of 950. 25 mm diameter's change also.

즉, 번수 30'S/1의 레이욘 단섬유 방적사에 합연시 Z 800TPM의 상연을 주면, 방적사의 번수는 30S×0.95025=28.5'S가 되고 이를 공통식 번수(Nm)로 환산하면 48.24'S가 된다. 따라서 방적사의 단면직경(d')은 상기 식(1)에 의하여 아래와 같다.That is, if the rayon short-fiber spun yarn of 30 ' S / 1 is combined with Z 800TPM, the number of spun yarn is 30 S x 0.95025 = 28. 5 ' S , which is converted to the common number (Nm), becomes 48. 24 ' S. Therefore, the cross-sectional diameter (d ') of the yarn is as follows by the formula (1).

또한, 연축이 일어난 방적사의 트위스트 1피치에 상당하는 사장(h') 및 원주표면길이(l')는 다음과 같다.Further, the yarn length (h ') and the circumferential surface length (l') corresponding to the twist 1 pitch of the spun yarn in which the twitching occurred were as follows.

따라서 방적사 1m(1,000m)에 대한 필라멘트사의 공급길이는 800×1.25878=1007.025mm가 된다. 따라서 합연시 필라멘트사가 방적사의 주위를 감는다고 가정하면 장,단복하사를 합연시 정확한 장력(Tension)을 맞추기 위해서는 Z 800TPM의 꼬임을 줄때는 필라멘트사를 0.7% 오버 피이딩(over feeding)해야 한다. 제2도에 도시된 바와같이 합연공정에서 필라멘트사는 연산장치(6)에 의해서 오버 피이드율인 0.7%가 결정되고 이 오버 피이드율에 의해 피이드 로울러(4)에서 송출량을 조절함으로서 장력이 균일한 합연복합사를 제조할 수 있다. 장력조절장치(3)는 실에 일정한 권취장력을 가하여 줌으로서 드럼(5)에 합연사를 권취할때 어느 정도 단단하게 감을 수 있게 해주는 장치이다.Therefore, the feeding length of filament yarn for 1 m (1,000 m) of spun yarn is 800 × 1.25878 = 1007.025 mm. Therefore, assuming that the filament yarns are wound around the yarn during joining, in order to match the correct tension when joining the long and short yarns, it is necessary to overfeed the filament yarn by 0.7% when twisting the Z 800TPM. As shown in FIG. 2, in the joining process, the filament yarn is determined by the calculating device 6, and the overfeed rate is 0.7%, and the overfeed rate is used to adjust the amount of feed from the feed roller 4 so that the tension is uniform. Composite yarns can be produced. Tension control device (3) is a device that can be wound to some extent when winding the twisted yarn on the drum (5) by applying a constant winding tension to the thread.

따라서 합연시 필라멘트사의 공급길이를 방적사의 번수 및 연방향과 연수에 따라 조절함으로써 필라멘트사의 장력차이를 없도록 하여 균일한 품질특성을 갖는 합연복합사를 제조할 수 있다.Therefore, it is possible to manufacture a jointed composite yarn having uniform quality characteristics by controlling the supply length of the filament yarn in accordance with the number of yarns and the direction and number of years of filament yarn so as to avoid the tension difference.
