が困難であった。2. Prior Art> A conventional cotton-covered core yarn has a front roller (4, 4) and a nigeron (3, 5) as shown in FIG.
), the core yarn (7) is fed into the core guide roll through a tensor, and is held between the front rollers (4, 4) together with the effect yarn (1) that constitutes the seedling layer. A Φ core yarn is formed. In this case, it is difficult to control the necessary tension to be applied to the core yarn (7), and therefore the result is a simple twisting effect, making it impossible to achieve a satisfactory covering of the cotton fibers. It was difficult.

As a result, the grooved portion of the roller (12) cannot grip the cotton fibers reliably, resulting in an uneven draft when covering the core yarn (7), and the control of the core yarn is also unstable. As a result, a part of the core yarn is exposed on the outside of the overlapping fiber (effect yarn), resulting in a disadvantage of deteriorating the appearance.

A method for manufacturing fancy yarn as described in Japanese Patent No. 18055 is also known, but in the former case, an elastic yarn is used as the core yarn, and the effect yarn becomes the core yarn due to the contraction of the elastic core yarn. It is constructed to cover the surrounding area, and therefore cannot be applied when the core yarn is made of something other than an elastic body. In the latter case, the method involves using two twisted yarns as the core yarn and covering the floating yarn on top.In this case, it is possible to hide the core yarn inside the effect yarn so that it is not exposed. It is not possible to create special fancy effects.

。<Problems to be Solved by the Invention> The present invention solves the above-mentioned conventional problems and hides the core yarn in a state where it is almost completely located in the center of the effect yarn. The object of the present invention is to provide an improved manufacturing method for producing cotton-covered core yarns that are capable of producing cotton-covered core yarns.

, 4) from the gripping point (15) to the winding part (14), the core yarn (7) having a constant tension is the center, and the cotton roving (1) has a smaller repulsive force than the core yarn. is designed to wrap around the core thread (7). When using synthetic fiber filament yarn such as polyester or nylon as the core yarn,
The gripping point (15) of the front rollers (4, 4) and the winding part (
In order to make the core yarn tension between the front rollers (4, 4) larger than the tension of the effect yarn, a certain range of tension is applied to the core yarn fed to the gripping point (15) of the front rollers. Adjust the core yarn delivery speed to the front roller (
As a result of experiments, the present invention has found that it is effective to make the surface speed smaller than the surface speed of the front rollers (4, 4), that is, to cause the core yarn (7) to slip slightly with respect to the front rollers (4, 4).

った。The core yarn is connected to the tension adjustment device (9) and the front rollers (4, 4
) If a constant tension is applied between rollers (9/, 9#)
), so in order to control this slip, the roller (9) that constitutes the tension adjustment device (9) is
As one of 'T9'), a roller having a high friction anti-slip function such as a rubber coated roller is used. The tension applied between the tension adjustment device (9) and the front rollers (4, 4) varies depending on the core yarn (7) used; The feeding speed ratio of yarn (7) and cotton roving (1) is 1:1.02 to 1:1.
When the ratio was within the range of 60, the covering state was extremely good.

7) surface exposure occurs, and if the ratio is 1:1.60 or more, the core yarn tension is too large, causing breakage of the core yarn (7) or making it difficult to maintain the desired tension due to a slip phenomenon.

従動する。In the tension adjusting device (9) composed of a pair of rollers (9') (9) used in carrying out the present invention, the tension roller (9')
') is made of a hard t% flora 9' made of metal or the like.
’), in which case a rubber tension roller (
For example, the pressure applied by the rollers (9') to the rollers (9') is approximately 1ψ
- It is desirable to keep it at around -. The core yarn (7) is wrapped once around the rubber tension roller (9') to maintain a constant tension (1,5
~4.0 g/d) in the direction of the gripping point (15) of the front roller (4, 4), and the rubber tension roller (91) is driven by the metal 4 drive roller (9 do.
従って上記した張力と供給速度比の条件は、コア糸がこ

性上の利点とを併有することとなる。A 27T8 cotton-covered core yarn was produced by the method of the present invention using 100 denier, ester filament yarn as the core yarn and 54'S fleece cotton roving as the effect yarn, and its U% was measured. The average is about 7-8-, which is much better than the 11-12 of the normal 30.3 P/C blend yarn U-chi, and the covering effect is very excellent, and the core is a fleece draft with a force of 41 J. We were able to confirm the fact that there were almost no problems caused by the introduction of thread. (In the above accident, the supply speed ratio of both rollers was l:
1.10. (This was carried out under the conditions of core yarn tension 3.1 FL/d) <Effects of the invention> In the present invention, for example, fleece-like cotton roving that is easy to dye is used as the effect yarn, and the core yarn is If you use polyester yarn, which is difficult to dye but has strong tensile strength, to make the cotton-covered core yarn, you will have the advantage of dyeing only the dyeing of the cotton roving, and the physical property that the core yarn will reinforce the tensile strength. This will combine the above advantages.

られることは当業者にとって明らかであろう。As described above, according to the present invention, by providing an existing cotton spinning machine with a very simple core yarn tension adjustment device, a synthetic fiber yarn for tensile force reinforcement is used as a core, and easily dyeable cotton fibers are arranged around it. It is possible to easily obtain a cotton-covered core yarn that is sufficiently covered and has both the physical properties of a core yarn and a covered yarn. It will be clear to those skilled in the art that an effective core yarn can be obtained by using, for example, cupro or vinylon fiber roving produced by a cotton spinning method instead of cotton roving.
