Abstract

Spinning yarn-like multi-bulked filament yarn having excellent tenile strength was manufd. by generating loops on the surface of false-twisted yarn and by stabilizing the loops with secondary twisting yarn. The stabilized loops were cut by passing the loops through the friction device which can adjust the up-down moving range of adjustable ring.

The present invention is composed of a loop-shaped first winding yarn and a second winding yarn for stabilizing the loop around the screen of the combustible screening, and cuts the loop to form a spun composite bulky filament yarn. In manufacturing, it is possible to precisely control the friction device for cutting the loops and to cut only the loop parts without damaging the screening and winding parts so as to maintain sufficient strength. will be. According to Special Publication No. 79-1626, which is known as a method for producing spun-fiber composite bulky filament yarns, the loops of the surface of the composite sublime yarns are cut by close abrasion to the rotating roughening body. There was a flaw that could not be gained enough strength. The present invention is to be precisely controlled by cutting the gap of the friction body with respect to the core of the composite yarn, it is characterized in that only the loops projected on the surface accurately cut bar according to the present invention in detail as follows.

Referring to the drawings illustrating the present invention can be divided into three parts as shown in FIG.

The first is the combustible part from (1) to (10)

The second is the winding and balloon formation from (11) to (15),

Thirdly, it is divided into the friction cutting part of (16), and the combustible part, the winding part, and the balun forming part are discontinuously possible, but there is a possibility of generating a lubrication when there is unnecessary friction due to the unstable loop winding part drawn out from the combustible part. It is better to do it continuously.

(A) of Fig. 1 is a screening and is fed to the heater (8) through the guide (1), the tension adjusting device (2), and through the supply roll (3). 1), the feed roller having an overfeed of 105-200% compared to the feed roller 3 through the separate guide 4 tension control device 5 in the same manner as (A). The upper surface 7 of the right feed roller 3 is brought into contact with the upper surface 7, and is fed to the combustible area through the heater 8 in combination with the screening.

At this time, (b) is about 1 / 5-4 / 5 thicker than screening (a) in terms of stability and strength, but more than that.

The yarn supplied to the Gayeon area is given a kite by the combustible spindle (9), and the form of echocardiography is wound around the screen as shown in Fig. 4 and the surface of the supply roller (3) (7). It is partially overlapped by fine tremor while having contact with This type of echocardiography is decomposed by the combustible spindles 9 after heat setting after passing through the heater 8, and the overlapped part is released and formed as a myriad of loops on the screening as shown in FIG. 5, and is drawn by the take-out roller 10. .

As described above, the twisted yarn has a lack of stability, and when the friction is applied, the yarn is pushed toward the dead sand to form a lubrication, so it is necessary to stabilize it immediately. In the present invention, by using a spindle box that can rotate at 5,000-10,000 RPM by a rotating belt 11 as shown in (12) of FIG. 1, it is continuously wound with a second winding yarn to stabilize and form a simultaneous balun surface The loops ejected to were rubbed and cut by the porous friction material 1 '. More specifically, the combustible work drawn through the take-out roller 10 is wound into a second winding yarn (C) which is fitted to the spindle and rotates with the spindle while passing through the spindle 13 rotating at 5,000-10,000 rpm. 6 and 15 to form a balun through the guide 14 and 15 to form a moor passing through the friction device 16 while rotating the guide 17, the roller 18, the guide 19, It is wound by the winding roller 21 via the reciprocating guide 20. As shown in Fig. 2, the friction device is composed of a porous friction material (1 '), a dead end ring (2'), a friction cabinet (3 ') and a ring adjusting screw (4'). Cover (5´) cover set screw (6´) set screw (7´) ceramic eyelet (8 ′) The core of the present invention is to cut only the lupu without damaging the screening by adjusting the distance between the friction agent 1 'and the yarn by the adjusting ring 2' according to the degree.

That is, as shown in FIG. 1, when the average length of the loop is ℓ, the distance between the core of the yarn and the frictional agent 1 'is maintained at l> ″ g0, and this distance should be precisely controlled because it is fine. The distance was controlled by the following equation. As shown in the model diagram of FIG. 8, when the contact point 0 with the ceramic eyelet, the contact point P with the friction body, and the slope control ring contact point R ₀ are in a straight line, that is, when the distance is zero, the default position is used. When the adjusting ring (2 ') is lowered by X, the linear distance between the screen and the friction body l' has the following relationship.
