Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a recycling waste synthetic resin,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing civil engineering fibers using waste synthetic resin regenerated yarn, and its object is to extract recycled yarns using waste synthetic resin and mix them with new yarn yarns at an appropriate ratio, While reducing energy consumption and environmental pollution due to the recycling of waste synthetic resin.

The fiber used for civil engineering is clearly distinguished from ordinary fiber. It is installed on soft ground, embankment slope, excavation slope or reinforced slope for civil engineering work, and reinforces the supporting force in the strong strength, so that the loss of soil caused by rainfall, Or to provide the strength to enter equipment during the soft ground improvement work.

Geosynthetics is a polymer synthetic fiber product that solves the problem of low strength of natural fiber materials. It is made of polypropylene, polyester, polyethylene, polyacrynitril, nylon, etc. It includes geotextile (porous product formed by woven synthetic fiber), geomembranes (geomembranes as car-accepting products), geogrids (high strength products) and geotextile-related products and has excellent workability, applicability and economy Recently, various civil engineering structures have been widely used as reinforcement, filter, drainage, separation, containment and anti-erosion prevention materials.

In recent years, as the applied structures of geosynthetics such as high-speed trains, underground structures, and waste landfills are becoming more diversified, larger and more difficult as well as large-scale reclamation works, development of safe and economical application techniques is required for each structure.

In order to cope with such a situation, applicants of the present application have also proposed methods and articles for manufacturing various types of fiber mats, which are disclosed in Korean Patent Registration No. 10-0636073.

This is to weave a civil engineering fabric in which warp and weft yarns are yarn-fed, weft yarn, weft yarn and weft yarn fed by warp knitting machine in a lattice-like lattice weave in plain weave and twill weave, The warp yarn is supplied to the warp yarn at an appropriate interval while supplying warp yarns to the weft yarn feeder, so that the warp yarns are formed in the oblique running direction. Further, Thereby forming another lattice on the lattice in the weft direction.

However, such a conventional prior art patent has the unique advantage that the strength is increased by newly forming the ribs in the plain weave and the twill weave of the weaving civil engineering fabrics, but the yarn for weaving the civil engineering fibers retains its strength There is a problem that the manufacturing cost is increased by using only the new material.

If the woven fabric can be woven using the waste water synthetic resin waste recycled waste paper without using the new material yarn as described above, it is possible to significantly reduce the manufacturing cost and to minimize the environmental pollution as well as the energy saving in terms of recycling the waste synthetic resin It can have an excellent advantage.

However, although it was possible to weave the civil engineering fiber using the waste synthetic resin after regenerating the waste synthetic resin, that is, regenerated yarn, the strength of the waste synthetic resin may not be maintained appropriately for the civil engineering fiber Or the regenerated yarn is difficult to be made of filament yarn, so that it can not be applied in practice.

In other words, there are two methods for producing regenerated yarn using waste synthetic resin. First, waste synthetic resin is melted to produce a thin film, and then finely cut such as thin yarn to produce regenerated yarn I can do it.

The regenerated product thus produced has a problem in that it can not easily be recycled as a waste synthetic resin but can not be used as a civil engineering fiber because the strength of the waste synthetic resin is not maintained sufficiently even though it has an advantage that it can be easily manufactured into a regenerated yarn .

As another method, the filament yarn can be used as a filament yarn. However, the filament yarn is composed of a very small number of fine yarns to form one yarn, so that the waste synthetic resin can not be recycled into a thin yarn constituting a filament yarn There was a structural problem.

That is, in order to produce filament yarn, very fine dust or foreign matter should not be introduced at all, but since waste synthetic resin contains various foreign matter and dust, it is very difficult to produce filament yarn by using waste synthetic resin, It was a characteristic that cost could be enormous.

Therefore, although the waste synthetic resin is intended to be recycled to produce the civil engineering fiber, the strength of the waste synthetic resin is not maintained or is difficult to manufacture. It is reality that there is.

In particular, since synthetic resins are very light and hard, they are easy to mold in various shapes and shapes, and have various advantages such as good decay, they are widely used in various fields such as home and industrial fields have.

However, due to the increase in usage due to the acceleration of industrial development, the amount to be discarded is continuously increasing, and the waste synthetic resin that has been used after being used in this way has been left as it is not decomposed or decayed even after several decades, Although the same waste synthetic resin is partially regenerated, most of it is applied only to the molding products using the mold, which causes a waste of valuable resources such as the inability to appropriately recycle the waste synthetic resin, which is generated frequently.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to provide a method of manufacturing waste synthetic resin by using waste synthetic resin which is used after being used once, The present invention provides a device for manufacturing civil engineering fibers using recycled synthetic resin recycled yarn which can significantly reduce the production cost of civil engineering fibers as it can manufacture civil engineering fibers by using waste water purification facilities at the same time. .

In other words, since the present invention uses waste synthetic resin that can be recycled for civil engineering fiber that is installed to be buried in most of the ground, the manufacturing cost of civil engineering fiber is greatly reduced, and the waste synthetic resin that is used once and used can be recycled It has the characteristic of being.

Particularly, the present invention can be mass-produced by automatically and continuously manufacturing the new yarn and the waste synthetic resin regenerated yarn by mixing them in an arbitrary suitable ratio, and as an automated machine. In addition, the waste synthetic resin regeneration yarn The present invention also provides an apparatus for manufacturing civil engineering fibers using the same.

In order to accomplish the above object, the present invention is achieved by appropriately mixing a waste synthetic resin recycled yarn recycled with a waste synthetic resin together with a new yarn, and automatically and continuously weaving the weaving yarn for civil engineering.

The present invention comprises a manufacturing apparatus for producing a waste synthetic resin as a regenerated film in the form of a film, and then weaving the regenerated yarn and the new yarn at an appropriate ratio, and the apparatus for separating the regenerated yarn and the regenerated yarn, A warp feeding means for feeding a weft yarn to the warp yarn feeding means and a warp yarn feeding means for aligning and delivering the warp yarn and the regenerated yarn fed from the warp yarn feeding means at an appropriate ratio, And a dougher.

According to the present invention, the recycled yarn produced by recycling the waste synthetic resin is used to weave the waste into the civil engineering fiber, thereby reducing energy consumption due to recycling of waste synthetic resin and environmental pollution.

Particularly, recycling of waste synthetic resin which is discarded after being used once is limited to most synthetic resin molded products, so that the scope of recycling is extremely limited. However, in the present invention, since the waste synthetic resin is made into recycled yarn, There is also a facility that can reduce energy consumption and reduce environmental pollution.

Further, the present invention has the effect of significantly reducing the production cost of the civil engineering fibers by using the waste synthetic resin as the weaving with the civil engineering fiber as described above, and this effect is very advantageous in terms of the use of the increasingly used civil engineering fibers .

In addition, since the present invention can use automated equipment in the use of recycled yarn using waste synthetic resin and can be manufactured in various forms according to the used civil engineering fibers, There is also an effect.

For example, among yarns composed of warp and weft yarns composed of a yarn guide made up of a yarn guide selected from polypropylene or polyester and composed of a yarn guide device including the configuration disclosed in Utility Model Application No. 20-2002-26466, .

The inclined conveying means 200 aligns the inclination drawn out from the yarn supplying means 100 and adjusts the tension to supply the inclination. The inclined conveying means 200 includes a body frame for aligning the yarn used as the inclined yarn, And a drive roller for tension control, and supplies the warp yarn to the knitting machine 300 and the doffer 400.

The weaving machine 300 is provided with a known weft supply means for supplying weft yarn to the fed yarn and supplying a separate weft yarn in a direction orthogonal to the yarn fed through the yarn supplying means 100.

The doffer 400 is formed with a plurality of heddles having longitudinals through which the warp passes, and is laid on top of the weaving machine 300 to weave a twill structure.

The fabric transport means 500 comprises a combination of suitable rollers to discharge the fabric woven in the weaving machine 300 and the docker 400.

The dehydrator 600 is composed of a pair of dehydrating rollers and a pair of heater rollers. The fabric is sprayed with water while the weft yarn B is supplied, and primarily flows through the dehydrating rollers to remove moisture. The water contained in the fabric is completely evaporated while the heater roller is continuously passed.

The winder 700 has a structure of a general winding device in which a fabric from which water is removed from the dehydrator 600 is wound.

The weaving system of the civil engineering fiber has the same structure as that of the conventional art. However, in the present invention, in order to use the recycled waste synthetic resin recovered by the waste synthetic resin, the manufacturing apparatus for weaving the civil engineering fiber by appropriately mixing with the new natural yarn is provided .

Therefore, when a plurality of cones 12, in which the new yarn 1 and the recycled yarn 2 are wound, are placed on the fixing table 11 in the yarn feeding means 100, the yarns corresponding to the yarns A are simultaneously Continuous and continuous supply.

In this case, the new yarn (1) is preferably made of filament yarn in order to maintain the high strength required for the characteristics of the civil engineering fiber. On the other hand, the recycled yarn (2) recycles waste synthetic resin once used and discarded Thus, by using a regenerated yarn which is cut into a thin yarn form and formed into a thin film form, they are different from each other in thickness (denier) so that the feeding means of the yarn is not a beam type but a krill type .

That is, since the deniers of the new yarn 1 and the regenerated yarn 2 are different from each other in the beam method in which the yarn is wound on one roller, the four layers are broken at the time of winding on the beam, 11), and a crill type method is used.

The ratio of the new yarn 1 to the regenerated yarn 2 is changed to 1: 1 or 2: 1 by changing the ratio of the used yarn to the regenerated yarn 1, , 1: 2, 1: 3, 1: 4, and the like.

In the yarn feeding means 100, the new yarn 1 and the regenerated yarn 2 are separately supplied to the new yarn 1 and the regenerated yarn 2, The regenerated yarn 2 is conveyed by the regenerating and conveying means 900 to the next weaving machine 300 and the doffer 400 respectively.

The new yarn feeding means 800 aligns the yarn yarns 1 drawn out from the yarn supplying means 100 and adjusts the appropriate tension so that the yarn is fed to the knitting machine 300 and the dewarer 300, (400). ≪ / RTI >

The transfer means 800 includes an aligning frame 80 for aligning the drawn new yarn 1 in a horizontal direction and a guide roller 81 and a tension roller 82.
