Abstract

Synthetic fiber multifilament interlaced yarn having a good tow collecting property was produced. Interlacing treatment was carried out in the condition of lower tensio to minimize irregularity of tension. Drawing roller (5) consists of part A(large diameter) and Part B (small diameter). Synthetic fiber multifilament yarn (1) was passed through the hating plate (4) and drawing roller (part A and part B) in order, the yarn in a moment. followed by the interlacing treatment passing through the nozzle (6). The condition of the diameter (A,B) and length (X,Y) of the drawing roller are follows.

)를 제조함에 있어서 교락부분과 미교락부분이 규칙적으로 형성되게함을 특징으로 한 집속성이 우수한 합성섬유 멀리필라멘트 교락사의 제조방법에 관한 것이다.In the present invention, the thermoplastic synthetic fiber multifilament yarn is drawn and fluid sprayed at the same time, the entangled portion and the unentangled portion are repeated.

The present invention relates to a method for producing a synthetic fiber mulfilament entangled yarn having excellent concentrating properties, characterized in that the entangled portion and the unentangled portion are formed regularly in the manufacture of).

In the conventional manufacturing method of synthetic fiber entangled yarn, since the entanglement process is performed under a relatively high tension after passing through the draw roller, the stroke of the winding part of the drawing machine in the process of forming the entangled portion and the unentangled portion alternately in the longitudinal direction of the thread thread ( Due to the tension nonuniformity generated from the stroke and the tension nonuniformity resulting from the difference in the spindle rotation speed, it was not a regular interlocking yarn and thus could not be produced.

The present invention is characterized in that the entanglement treatment in the storage force state in which the tension of thread thread is significantly reduced to minimize the tension non-uniformity as described above in detail as follows.

Figure 1 (b) is a conventional manufacturing method, the synthetic fiber mul filament yarn (1) stretched in the stretching area is passed through the one-stage drawing roller (10) and passed through the interlacer nozzle (6) installed in the lower portion of the entanglement treatment And winding on the spindle (9).

Figure 1 (a) is a manufacturing method of the present invention, the draw roller 5 is formed in two stages, as shown in Figure 2 is a large diameter A portion and a small diameter B portion. When the synthetic fiber multifilament yarn 1 passed through the heating plate 4 passes the portion A having a large diameter and passes the portion B having a small diameter, tension is remarkably reduced. In this process, when the synthetic fiber multifilament yarn (1) is passed through the interlacer nozzle (6) and entangled, the synthetic fiber multifilament yarn (2) is entangled under storage capacity, resulting in regular entanglement and non-entanglement. It is possible to manufacture a part of Kyora.

In addition, the present invention can solve the problem of deterioration in operating efficiency by increasing energy loss as well as cutting rate due to relatively high air pressure because it requires a entanglement treatment under a relatively high tension.

In the present invention, if the relationship between the long and short diameter parts A and B of the two-stage stretching roller 5 and the length X and Y of this part is satisfied, the interlocking yarn having excellent quality can be manufactured with good operability.
