In particular, the present invention relates to a method for producing a spraying spray in a simple and stable process by simultaneously spinning and stretching.

Conventional spinning yarns are wound by imparting a water-containing emulsion at a spinning speed of 900 to 15000 m / min in a spinning machine, and the unstretched yarn thus spind is subjected to a stretching process and then subjected to heat treatment to have a 10 to 12T / M. Flexible stretched yarns are used, which means that the conventional stretched yarns obtained by such a manufacturing method have to go through a number of processes, resulting in a high manufacturing cost and an increase in external inhibitory factors such as spinning, stretching, and heat treatment. It had many problems in producing uniform yarns suitable for dispersing spraying.

That is, the problem in the case of producing a branched yarn using such a flexible branched yarn

)과정에서 자연꼬임이 10내지 12T/M정도 발생하게 되고 연신사를 귄취할때 보빈(Bobbin)의 권량이 3.0kg이하로 제한되고, 분섬과정에서 매듭이 4내지 6EA/kg정도 발생되기 때문에 제직할 경우 제품의 고급화가 곤란하고,First, Creel's dismissal to stretch the undrawn yarn

Natural twist occurs in the process of 10 to 12T / M, and the bobbin volume of the bobbin (Bobbin) is limited to less than 3.0kg when weaving the drawing yarn, weaving because the knot is generated 4 ~ 6EA / kg during the process If you do not have high quality products,

Second, since the splitting process should be performed while removing the residual twist generated by using the conventional splitting machine when splitting flexible spraying spray, the complexity of process as well as the splitting performance are poor and the splitting speed is limited to 100 to 150m / min. As a result, it is pointed out that productivity is low and production cost is very high.

In addition, the filament is easily entangled and the fusion is easy to occur depending on the moisture content of the emulsion used in the production of the divided yarn, the cause of fusion and entanglement is the filament when the multifilament is passed on the stretch heat treatment roller at a high speed This is because the movement between the liver is severe and free movement (filament microphoneation) is likely to occur.

In particular, because the heat treatment at high temperature is easy to cause light fusion between single yarns and easy to entangle, there is a large difference in quality in the stretch heat treatment rollers according to the type of emulsion (때) used when producing the divided yarn.

In the conventional method of attaching the water-containing emulsion described above, when the water content of the water-containing emulsion applied during spinning becomes large, the strength decreases, and a type of spherical layer is generated in the outer ring of the unstretched filament. Rapid growth by heat leads to drawboards and poor homogeneity, resulting in severe filament migration and mild fusion. At this time, the thickness of the outermost spherical layer is determined according to the moisture content of the imparting oil, but even if the spherical layer of the same degree, if the spinning speed is high, deformation occurs rapidly and is easily cut off.

As a result, the conventional method for imparting a water-containing emulsion contains a number of problems as described above when the water content is high, and thus, significantly lowers the quality of the prepared spun-spray spray. When the water-containing emulsion is used, it is extremely difficult to lower the water content.

The purpose of the present invention is to provide a method for producing a polyester smoke-free spun yarn which is good in homogeneity and good dispersibility and can reduce manufacturing cost due to its simple manufacturing process.

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

In the present invention, in the manufacture of filament yarn for dispensing filament yarn by melt spinning thermoplastic polyester, the polyester (2) is discharged from the mold (1), the oil is edified and then the spinning guide (4, Using the oil roller (5) in which 6) is located, attach a non-water-containing oil having a viscosity of 1 to 5CTS to 0.3 to 1.4% per unit of unstretched yarn to oil it, and then stretch the heat treatment roller. (9) is a method for producing a polyester smoke-free island spraying, characterized in that the odor after the direct stretching to 7 to 10kg per drum at a odor speed of more than 3000m / min.

Reference numeral 3 is a cooling device, 7 is a separation guide, 8 is a draw roller, 10 is a spray guide, 11 is a grip point roller, 12 is a odor device.

When explaining the manufacturing process of the present invention in more detail as follows.

Referring to FIG. 1, the manufacturing process of the present invention will be described. The present invention is directed to a spinning guide after the polyester (2) yarn strand discharged from the mold (I) is cooled and solidified through the cooling device (3). Guided to (4, 6) is to oil ring while contacting the oil ring roller (5). At this time, the oiled multifilament is divided into single yarns by the spinning guide 4 to be attached to the non-water-containing emulsion according to the present invention, and then preheated and heated again in the heated draw roller 8 while being guided to the separation guide 7. Stretching is carried out at a constant magnification between the stretching heat treatment rollers 9. The multifilament separated by the spray guide 10 while being stretched in this way is wound by the gripper device 12 while being connected by the gripping point guide 11.

According to the present invention, it is generally preferred that the number of components is 4 to 12 and the single yarn denier after the stretching is 5 to 30 denier.

The present invention is to produce a lead-free stretched yarn by stretching directly, rather than twisting the spun undrawn yarn of the conventional manner, and using a non-water-containing oil (STRAI GHT TYPE) to improve the dispersibility, according to the present invention It is possible to produce a superior spraying yarn better.

The present invention will be described in detail with reference to Examples.

EXAMPLE

The polyethylene telephthalate of IV 0.64 (OCP method) was directly stretched after melt spinning at 290 ° C using the apparatus illustrated in FIG. 1, and then the emulsion and non-water emulsions were classified and used as shown in Table 1 below. After heating and heating, the spinning spraying agent was prepared while changing the speed of the take-out roller 8 and the speed of the stretched heat treatment roller 9, respectively, and the radioactive bactericidal agent and the splitting property were examined.

The non-water-containing oil (A) used here has a degree of 5CTS at room temperature of 20 ° C, and the composition includes mineral oil (65%), higher alcohol ester (25%), higher alcohol ether (7%), and phosphate (3%). The oil coating amount (0.8%) is contained, and the water-containing emulsion (B), that is, the emulsion zone emulsion, used here is an emulsion obtained by diluting the composition of the non-water-containing emulsion (A) to 10%.

TABLE 1

As shown in Table 1, when the powdered spray was prepared using the emulsion oil (B) as a comparative example in the above embodiment, various physical properties were significantly worse than those of the present invention, indicating that the method of the present invention is excellent. Able to know.

In particular, referring to Figure 2 (a) is a case of Comparative Examples 1 and 2 and (b) and (c) is a bactericide showing the case of Example 1 and Example 2, respectively, from which the emulsion emulsion In contrast, the production-dispersed spraying spray is extremely poor in comparison with the poorly-developed spraying agent, in which case the spinning spraying agent is manufactured by direct spinning and stretching using the non-water-containing emulsion. In addition, the conventional method using the emulsion emulsion has been shown to be a good product without the occurrence of acupuncture fusion phenomenon, compared to the fact that the separation of the salt is not possible due to the fusion phenomenon is impossible.

As described above, the polyester lead-free spun yarn according to the present invention is supplied with a non-water-containing emulsion unlike a conventional yarn for spinning using a water-containing emulsion, so that a good bactericidal agent can be produced, and the production of a very good splitting yarn is possible. In addition, the drawing board does not occur by heat during drawing, and the moisture content can be adjusted freely compared to the water-containing emulsion, and the spinning bacterium is very good, so that the sedimentation and spraying production can be produced with good splitting properties. As the process is not complicated and cumbersome, it is not only a simple process, but also lowers the manufacturing cost of the drawn yarn, and directly draws the unstretched unstretched yarn, thus minimizing the effects of external inhibitors generated in each process. With various advantages, such as the effect of producing yarn for splitting The.
