Abstract

A method for producing a falst twisted knop yarn of thermoplastic synthetic fiber having diversity by controling unit length and one repeat length of knop is discribed. The false twisted knop yarn includes multifilament. The interval of covering yarn guide and ground yarn is controled by freely moving of covering yarn guide, so as to form of knop is variated.

Description

Manufacturing method of thermoplastic synthetic twisted yarn (knop)

1 is an exemplary view showing an embodiment of the present invention.

2 is an illustration of the coating guide of the present invention.

3 is an enlarged view of the false twist height manufactured according to the present invention.

The present invention is artificially produced in the unit length and one-repeat length (knop) in the manufacture of the twisted yarn by twisting two thermoplastic synthetic fiber multifilament such as polyester or polyamide The present invention relates to a method for manufacturing thermoplastic synthetic fiber twisted yarn for quantitative adjustment.

[0003] A method for producing a coated yarn in a slop state of an irregular looped pile by using a combustor has been known from Patent Publication No. 79-1370.

In other words, the above-mentioned known technique adopts a technical means for forming slips and mills of the coated yarn around the screening by rubbing the coated yarn of supercharging with a rubber roller which rotates in the reverse direction immediately before the point of agreement with the screening. .

In other words, when the sheath is in the slip process, the tension is small, but when the circulation is interrupted, the tension is momentarily applied.

Therefore, due to the periodic tension difference of the coated yarn as described above, the point of coincidence with the screening fluctuates with a constant amplitude, thereby generating a slop. However, the above-described method for producing a slop yarn is not suitable for achieving the object of the present invention because it is very difficult to artificially and quantitatively adjust the degree of slip.

The present invention was made in view of the above problems to be able to manufacture a variety of flammable yarns by artificially and quantitatively control the height unit length and one circulation in the following according to the exemplary drawings as follows.

The screening (A) of the three fineness of thermoplastic synthetic fiber mulilament (A) is supplied under tension in the tension coil (1) and the supply roller (2) (2 '), and the coated yarn (B) is a finer degree than the screening (A). Through the guide (3) is to be interpreted as the armed state through the apostles (4) of the apostles (4 ') to unite in the examination (A).

At this time, since the threaded yarn 4 is located at right angles to the advancing direction of the coated yarn B, the coated yarn B is subjected to some resistance at the instant of passage. The screening (A) and the coated yarn (B) are subjected to the combustible processing as heat-fixed-decomposed in the bobbin (8) via the heater (5) and the delivery roller (7) (7 ') of the spindle (6). , The coated yarn B is wound up to the examination A while vibrating between the point C and the point C 'to be combined with the examination A. FIG. At this time, the coated yarn (B) has a TPM less than the rpm of the spindle (6) when it is raised from the point (C) to the point (C ′), and has a lot of TPM when downward, so that many TPM parts, That is, the tightly wound portion is known to form a high (K) by forming a file of a loop shape by the residual twist.

The present inventors pay attention to the experimental result that the height (K) produced is changed by changing the distance (D) between the apostle (4) and the screening (A) in the manufacturing process of the false twisted yarn, removing the four apostles (4 '). As illustrated in Figures 1 and 2,

TABLE 1

In the "c" shaped bracket (9) to move, and the eye 10 corresponding to the distance (D) on the surface of the one side of the bracket (9) and the position of the apostle (4) with a high information bolt (11) Adjustments were made. In other words, if the distance D is increased under the condition of manufacturing false twisted yarn, the tension of the coated yarn B is small and the vibration interval between the points C and C ′ increases, and thus the unit length d of the height K generated. And 1 circulation (d ') was found to increase proportionally.

In other words, if the distance D is constant under the conditions of manufacturing false twisted yarn, the length d and the one circulation field d 'of the generated height K are constant as illustrated in Tables 1 and 2. In manufacturing the false twisted yarn, if the unit length (d) or one circulation length (d ') of height (K) is determined in advance so as to correspond to the organization of the fabric, knit fabric or consumer, Artificially very simple to produce. A feature of the present invention is that it is possible to artificially and quantitatively change the shape of the height K by adjusting the distance D between the slope 4 and the examination A as described above.

In the present invention, the means for moving between the apostles 4 'is not limited to the embodiment, and any suitable technical means cannot be used to depart from the technical scope of the present invention.

Example 1

Processed under the flammable conditions, but the distance (D) of the guide (4) of the screening (A) and the coated yarn (B) to 5 m / m bar height (K) is 1.0m / m, the height of 1 circulation Regular burnt heights of 10 m / m were obtained.

Example 2

The length (d) of the height (K) was 15 m / m and the height was adjusted to 30 m / m in the combustible processing under the above flammable conditions, but the distance (D) between the screening (A) and the guide 4 of the coated yarn (B) was 30 m / m. One cycle length (d ') of 61m / m of regular bitumen was obtained.

Claims (1)

In manufacturing the twisted yarn (knop) by making the coated yarn (B) made of a thermoplastic synthetic fiber multifilament in an almost untensioned state wound around the screening (A) made of the thermoplastic synthetic fiber mulillapenten in tension state, The distance between the guide 4 of the coated yarn B and the screening A can be adjusted arbitrarily by allowing the guide 4 for the radiation B to move freely.
