Apparatus for controlling properties of yarn by thermal setting}

The present invention relates to a thermal setting property stabilization device of chemical fiber yarn, specifically, the present invention is a constant tension (tension) to the yarn of the general chemical fiber already manufactured, such as polyester, nylon, polyethylene, polylactic acid (PLA), etc. The present invention relates to a thermosetting material stabilization apparatus of a yarn which changes the physical properties of the yarn under a constant temperature, so that the yarn can be stabilized (reduced shrinkage and cut elongation), wrinkles are stabilized, and crystal structure is stabilized.

As a yarn for woven fabrics, it is common to use a stretched yarn manufactured by subjecting an undrawn yarn wound at a spinning speed of 1,000-1,500 m / min to a heat treatment as necessary via a drawing process. However, the stretched yarn obtained as the method requires many processes, and the manufacturing cost becomes high, and various external bad factors act synergistically in each process of spinning, stretching, and heat treatment, so that the yarn is uniform as a woven yarn. Haha had a lot of problems.

On the other hand, as a method of obtaining a stretched yarn-shaped structure only by a spinning process for the purpose of cost reduction,

(1) Direct spinning stretching method which draws continuously after winding without winding,

(2) simply increase the spinning speed up to several thousand meters to get a structure like stretched yarn,

(3) Various methods have been proposed to obtain a structure such as stretched yarn by performing high temperature heat treatment after the ejected yarn strands are solidified.

However, in the direct radial drawing method as in the method of (1), a yarn having a structure close to that of a conventional drawn yarn is obtained, and since the drawing process has a high speed, it requires a high heat treatment and has a high-performance heating roller. However, since the price of the device becomes expensive because the heating plate must be provided, and the current energy cost is getting higher, there is a problem in that the cost reduction as a total cost is very small and it cannot be employed as a production system of phenomena even if the operation aspect is added. .

Specifically, the method of (2) has been proposed in accordance with Japanese Patent No. 3104 No. 3104, US Patent No. 4134882, etc., but the yarn of a stretched yarn-like structure that can withstand practical use by this method. To achieve this, the winding speed must be super highway from 6,000m / min to 8,000 / min.

At this time, because of the extremely high speed, the concentration of single yarns in the process until the winding is regulated once as a roller is not sufficient, and the effect of air resistance or airflow accompanying each single yarn is greatly increased. This causes fluctuations in the thread, which causes the tension to be very large.

For this reason, the cutting of a single yarn is easy to generate | occur | produce, and the characteristic of the yarn obtained has the fault that it is easy to become nonuniform in thickness of a thread, and to become nonuniform in dyeing. In addition, the ultra-high spinning yarn has a very low boiling water shrinkage, which leads to less elasticity of the strands and a change in winding tension, resulting in uneven yarn cutting or uneven thickness of the yarn. It also has the drawback that it is easy to become stable, and stable operation is in a difficult situation.

In addition, the technical idea of the method (3) has been proposed in the publication of Patent Publication No. 13156, No. 13156, and the Patent Publication No. 52, No. 118030. In this method, however, it is necessary to heat-treat substantially a high temperature on the solidified yarn strands which are traveling on the highway. It is easy to cause trouble, and even if the thread is well threaded, it is very difficult to uniformly heat-treat each single yarn because of high temperature heat treatment. Problems such as uneven dyeing and tensile unevenness will occur.

In addition, despite the cost savings by eliminating the stretching process, high-performance heat treatment equipment is needed, and since the recent energy costs are increasing, total cost reduction is not possible, so this method cannot be used as a production system. On the other hand, it has been proposed as a Patent Publication No. 51,921, Published by Patent Publication No. 51, which gives a tension gradient and makes it recover at a winding speed of 2,500-4,000 m / min.

However, since this method does not use heat, a yarn such as a stretched yarn can be manufactured at a low price only by a spinning process, but a tension gradient between single yarns is not varied because a tension gradient is provided as a contact by a guide or the like to the released solidified strand. In particular, in the case where the number of filaments is large, the nonuniformity of the tension gradient between single yarns located in the inner and outer layers causes a nonuniformity of the structure, resulting in spots on the dyeing of the yarn or uneven tension.

In addition, when a contact is made to such an extent as to give a tension gradient, the surface of the yarn is cut by the contact, so that a closed point such as light powder is generated and the thread is cut may occur.

Particularly, in the case of polyester, the driving step before the crystallization of the winding speed of 2,500-4,000 m / min is also overlapped to cause single yarn cutting, or even if the single yarn cutting is not performed, There is a drawback that, as a cause of fluffing, poor passability during more complicated machining and significantly lower operability in spinning and complex machining steps.

As such, a number of methods for manufacturing the same yarn as the stretched yarn by omitting the stretching process as a separate process are proposed. However, as a yarn for woven fabric, it is developed as a production system in terms of quality and industrial quality of the woven fabric. No way has been proposed until now.

Therefore, the present invention is to stabilize the yarn by adjusting the physical properties of the yarn given a constant tension and a constant temperature to the yarn of the general chemical fiber already manufactured to solve the above problems (reduction of residual shrinkage and reduction of cutting elongation) We have developed a thermal setting material stabilization device of Hansa to stabilize the wrinkles, stabilize the crystal structure and obtain certain mechanical properties.

In order to achieve the object of the present invention described above, the present invention is to stabilize the physical properties of the yarn under a constant tension and a constant temperature to the yarn of the general chemical fiber already manufactured (stabilization of the shrinkage (reduction and reduction of residual shrinkage) The purpose of the present invention is to provide a thermal setting material stabilization device of Hansa to reduce elongation, stabilize wrinkles, stabilize crystal structure, and obtain constant mechanical properties.

Another object of the present invention is to repeatedly expand / contract the yarn by the rotational speed difference obtained by varying the size of the pulley integrally installed on the pair of rolls for winding the yarn drawn from the yarn supplying portion, Another object of the present invention is to maintain physical properties.

Hereinafter, with reference to the accompanying drawings will be described in detail the contents of the present invention.

In the thermal setting material stabilization apparatus of the present invention (1), as shown in Figure 1, the first and second support (11, 12) is configured in a rectangular frame shape by a plurality of vertical and horizontal frames are installed, After the first and second supports are opposed to each other at regular intervals, a plurality of support frames 13 are welded therebetween, or the body 10 is completed by using bolts or nuts.

Horizontal and vertical frames were used for the main body 10, but a plate may be used if necessary. Such configuration changes can be easily made by those skilled in the art.

In addition, first and second guide means 50 and 60 for guiding the drawing yarn L drawn from the yarn supply part 40 are installed at both sides of the support frame located at the top of the support frame 13.

The first and second guide means (50, 60) are the first and second guide rolls (51, 61) installed on both sides of the uppermost support frame and the yarn drawn from the first guide roll (51) first roll Auxiliary guide roll 52 for transferring to 30, and a second auxiliary guide roll for discharging the yarn discharged from the second roll 31 via the first roll 30 toward the bobbin (not shown) It consists of 62.

The first roll 30 and the second roll 31 are axially supported by the bearing B on the upper and lower front sides of the main body 10.

A first pulley P1 is provided on one side of the first roll 30, and a second pulley P2 is provided on one side of the second roll 31, and a belt V is installed therebetween. .

At this time, the first pulley (P1) is formed to a diameter 1/10 larger than the second pulley (P2), thereby repeating the contraction / relaxation of the yarn wound on the first and second rolls (30, 31) The elongation of the yarn can be kept constant.

For example, the diameter of the first pulley (P1) is formed to be 1.02 ~ 1.1 times larger than the diameter of the second pulley (P2), the rotational speed of the second pulley 2-10% more than the first pulley Rotates quickly.

At this time, the tension of 0.2 ~ 1g per denier should be added to the yarn (에서) supplied from the yarn supply unit 40 can achieve a smooth physical properties of the yarn.

Further, a third pulley P3 is provided on the axial extension line that supports the second roll 31, and the third pulley P3 is installed in cooperation with the fourth pulley P4 by the belt V, The fourth pulley P4 is integrally installed on the feeding motor M shaft.

A yarn separation guide part 70 is installed between the first roll and the second roll 30 and 31 so that the yarns transferred between the first roll and the second roll 30 and 31 are not twisted with each other. It serves to convey. That is, the yarn separation induction part 70 is composed of a support body 71 that is formed in a bar (bar) form long and a plurality of pins (71a) are provided at regular intervals along the length of the support body.

On the other hand, the heating device (H) for applying heat to adjust and stabilize to have a certain physical properties while the yarn wound on the first roll and the second roll rotated simultaneously by the drive means 20 is the first roll And between the second rolls 30 and 31.

The feeding motor and the heating apparatus are operated by a control unit and a power supply unit (not shown).

Therefore, the thermal setting material stabilization apparatus 1 of the yarn configured as described above supplies power to a power supply not shown, and when the switch is 'on', the heating device H is preset in the control unit (not shown). It will generate as much as the set value.

Subsequently, the yarn L is wound from the yarn supply unit 40 to the first and second rolls 30 and 31 via the guide means 50, and then connected to a bobbin not shown through the second guide means 60. do.

When the yarn is pulled by the operation of the next bobbin and the fitting motor M is operated, the rotational force of the feeding motor M is transmitted through the fourth and third pulleys P4 and P3 to the second and first pulleys. (P2, P1)), and the rotational force of the second and first pulleys (P2, P1) is transmitted to the second and first rolls (31, 30).

Therefore, the yarn L is expanded and contracted by the rotation and heating device H so that the first and second pulleys 30 and 31 maintain a constant tension.

At this time, the first pulley (P1) is formed by approximately 10% larger diameter than the second pulley (P2), thereby increasing the speed of rotation of the second roll (31) directly receiving the rotational force from the feeding motor (M) And, the rotational speed of the first roll 30, which is indirectly transmitted to the rotational force, rotates more slowly and slowly.

Therefore, by varying the speed at which the yarn L is wound on the first and second rolls as described above, stabilization of the yarn by repeated operations of expansion and contraction applied to the yarn L (reduction of residual shrinkage and cutting elongation) Reduction, stabilization of wrinkles, stability of crystal structure and constant mechanical properties.
