The present invention is to supply at least three different fiber sliver (Sliver) to one spindle in the spinning process during spinning process, before drafting and twisting (splitting) By producing different tension control supply through the sliver separator guide device, press roller, and trumpets, the driver can produce a double-fiber dual structure loob yarn by a spinning machine. This relates to a method for producing a double-structured spun yarn for producing a finished yarn by a known spinning process.

Various types of core yarn methods have been proposed in which the periphery of the core is covered with a coated yarn, but this method is a double structure in which two or more kinds of different fibers are formed in a combustible state. Not only could it not be actively wrapped around the screening, but there was a flaw in the soft touch caused by the lecture.

Therefore, in order to improve this, it is necessary to use a special twisting machine having a special twisting device so that not only the production efficiency is lowered but also the manufacturing cost increases.

) Is also proposed as a double-structured yarn that uses filament yarn or spuntex yarn and covers the periphery of the screen with short-fiber yarn, but it is expensive and limited in terms of use.

The present invention uses a spinning machine in a general spinning facility, but adds a heterogeneous fiber separation supply device and a tension control device, and the draft and the combustor are easily distinguished as heterogeneous fibers without any modification. By obtaining a double-structured roobone yarn, and spinning it, a double-structured yarn in which the core and the periphery are separately formed as heterogeneous fibers.

The furnace completed in the draft and combustor of the spinning machine by inducing the trumpet under pressure by the press roller designed to apply different tension to each of the fiber sliver and the fiber sliver An orb yarn is obtained, and the finished double-structured yarn of the present invention is obtained by spinning the loob yarn in a spinning machine.

Therefore, the core of the double-structured yarn according to the present invention is composed of short fibers having a relatively high tensile strength, such as polyester or nylon, and the periphery is composed of natural fibers such as cotton or rayon, so that the advantages of synthetic fibers and natural fibers It relates to a manufacturing method that can easily obtain a double-structured yarn having excellent physical properties.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a process schematic diagram of a spinning process used in the practice of the present invention. The sliver supplied to the spindle 1 in a conventional spinning machine consists of three or more multi-fiber heterofiber slivers.

)를 형성할 폴리에스터 또는 나이론 화이버의 스라이버인 것이다.In the case of FIG. 1, the slivers 2 and 3 are slivers of cotton or rayon fibers to form the periphery, and the slivers 4 are screened.

It is a scriber of polyester or nylon fiber to form).

These slivers 2, 3, and 4 are guided by the guide rollers 5 to pass through separate guide holes 7, 7 ', 7 "of the sliber separator guide 6, The sliber 4 to be formed is guided to the lower guide hole 7 "and the sliber 2 and 3 to form the periphery is guided to the upper guide holes 7 and 7 'to press roller 8 It is pressed by a constant wave force.

At this time, the scriber 4 is to form the examination 4 and the swivel 2 (3) to form the main yarn is subjected to the tension under different conditions, respectively, as shown in 3 (a) ) Is placed in an elliptical state and the main twisting unit (10, 10 ') is guided to the trumpet (11) in a state surrounding the right and left sides of the examination unit is supplied to the conventional draft unit 12 and the combustible unit (13) Lose.

At this time, the main speaker wraps the screening by the collector device between the front roller and the second roller of the draft section, and the main screening section (10) (10 ') comes out and the screening (9) completely enters the third (b). As shown in Fig. 2), the loobyan of the present invention is obtained.

The lobed yarns are spun in a conventional spinning machine to obtain the completed double-structured yarn of the present invention.

In the figure, reference numeral 14 denotes a flyer.

When the finished Lowab is subjected to a predetermined draft and twist in a spinning machine, the outer edge of the core made of polyester or nylon fiber is formed with cotton or rayon fibers to form a peripheral part of the present invention. You get a rescue yarn.

Therefore, the double-structured yarn of the present invention has a very tough and morphological stability because the polyester or nylon fibers form a core inside, and excellent in shrinkage rate or wrinkle retention even when washed with water, and the outside is made of only cotton or artificial fibers to absorb moisture. This excellent skin health is good, and the contamination is not well, even if it is contaminated, it is characterized by being easily removed, it is possible to obtain a double-structured yarn of excellent physical properties having the advantages of synthetic fibers and natural fibers at the same time.

Claims (3)

In the spinning process during the spinning process, several strands of different fiber slivers are supplied to each spindle, and the sliver separator guides before the draft and twisting. Separator guide (6), press roller (8) and trumpets (11) are used to adjust the tension of the scriber (4) and the scriber (2) (3) of the main twister differently. The method for producing a double-structured yarn of the present invention completed by a known spinning process after producing a heterofiber double-structured Rohhamsa yarn by a spinning machine. 2. The sliver separator guide device (6) according to claim 1, wherein the sliver separator guide device (6) has the same number of sliver guide holes (7) (7 ') (7' ') in two stages up and down as the number of slivers supplied to one spindle. . 3. The guiding hole (7) (7 ') of the upper part of the sliver guiding hole is passed through the siver of the fiber to form the periphery and the lower guide hole (7' ') of the heterogeneous fiber to form the core part Pass the scriber.
