Description

[0001] Description [0002] Highly functional polypropylene filaments and products containing di-lighter

More particularly, the master batch chip containing ilite is mixed with a general polymer resin chip, melted and made into a desired shape of filament yarn. When a master batch chip or an injection molded product is manufactured, a mixture of 4 to 20% by weight of a master batch chip and 80 to 96% by weight of a general polymer resin chip is mixed with a daily light powder having a particle size of 1,000 to 2,000 mesh, Can be used as a highly functional eco-friendly fiber material by forming a chip or an injection material having a content of 1 to 10 wt%

Considering the clogging of the spinning nozzle and the tensile properties of the yarn, 4 to 20% by weight of a master batch chip containing an ilite having a particle size of 3,000 mesh or higher and a general polymer resin chip Functionalized polypropylene filaments and products which can be used as a highly functional eco-friendly clothing material or packaging material by obtaining a material having an overall Illyite content of 0.5 to 5 wt% by mixing 80 to 98 wt% .

Polyolefin-based fibers can be classified into polypropylene and polyethylene fibers. The polypropylene fiber has a high molecular weight and high crystallinity and has a melting point as high as about 165 to 173 DEG C and a softening point of 140 to 160 DEG C as well as a comparatively high specific gravity of 0.91 and a tensile strength, a bending strength, It is an excellent material in terms of mechanical properties such as high strength and bending fatigue resistance. In addition, polypropylene is an excellent material as a packaging material because of its excellent transparency.

Particularly, the polypropylene is mainly used as a quick-drying and light-weight leisurewear because it has a low process water content and a low specific gravity and is excellent in transparency. Therefore, it is very suitable as a packaging material and can be used for storing and transporting various foods such as cereals, seaweeds, It can also be used as material.

In recent years, a variety of functional inorganic materials such as ilite have been studied, and the unique efficacy has been revealed. In particular, ilite has excellent efficacy of far-infrared radiation, and thus has an effect of improving health functionalities and storage of foods.

Despite the effectiveness of such functional inorganic materials, it is very difficult to uniformly mix the functional inorganic materials with the polyolefin-based resin without changing the physical properties, which is a hindrance to commercialization.

Therefore, there has been no release of functionalized polypropylene filament materials containing anilite at present, and a master batch chip having a large content of inorganic materials is mixed with a general synthetic fiber chip to form a molded product, The process is very complicated, the power consumption is high, the manufacturing cost is high,

Since the difference in specific gravity between the ilite and the polymer resin is large, especially the ilite is soft like clay, it is difficult to uniformly mix it with the polymer resin rather than the powder of the other hard ceramic mineral, and it is difficult to manufacture the master batch chip itself at a high concentration. Therefore, according to the presently known methods, the manufacturing process is complicated and not only the manufacturing cost is high, but also various additives are applied and thickly applied to the surface, so that the operation time of the mixer becomes long, and the extruder has a magnification of 36 times or more The light can be uniformly dispersed only when it is made, and it has been difficult to obtain uniform performance and effects.

Specifically, for example, in Korean Patent Publication No. 267350, 60 to 90% of pulverized general chips and 10 to 40% of Illite superfine powder are mixed to form a binder which is a silicone component so that a dispersant and a vehicle are well mixed to prevent powder aggregation It has been proposed to produce a final master batch chip by injecting it into each process and extruding it. However, when crushing a general chip, it is difficult to crush due to the inherent property of a general chip, which is a petrochemical product, Cost burden is generated due to the necessity of the manufactured pulverizer, and the manufacturing process of the Illite superfine powder is complicated and high cost is required, resulting in a disadvantage that an expensive master batch chip is produced. Therefore, it is very difficult to uniformly incorporate the niobium powder into the resin, so there are many difficulties in actual commercialization thereof.

As a result of solving these drawbacks, polypropylene is mainly used as a highly functional eco-friendly material for a variety of leisure apparel such as light outdoor due to multi-functional ilite. If a high functionality is given to existing polypropylene, It is expected to be more preferable.

In order to impart such functionality, far infrared rays, negative ions. Some studies have been made on the addition of Illight, a natural mineral with excellent deodorization and antibacterial properties, to polypropylene.

At present, there is no prior art of functionalized polyolefin filament containing ilite, but only the registered patent of my functional pp film

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a component comprises a component, it is understood that it may include other components, not control of the other component, unless specifically stated otherwise.

First, in the present invention, the master batch chip containing ilite is mixed with a general polymer resin chip, melted and made into a desired shape of filament yarn. In the case of producing a master batch chip, a master batch chip prepared by using a daylight powder having a particle size of 1000 to 2,000 mesh is used to prepare a master batch chip of 4 to 20% by weight and 80 to 96% by weight of a general polymeric resin chip As a whole, can be used as a chip or an injection molded product having a content of 1 to 10% by weight.

Considering the clogging of the spinning nozzle and the tensile characteristics of the yarn, 4 to 20% by weight of a master batch chip containing Ilite having a particle size of 3,000 mesh or higher and a general polymer resin chip 80 To 98% by weight, and melt-spinning the mixture to obtain a material having an overall Illyrite content of 0.5 to 5% by weight, and can be used as a filament yarn used for a highly functional eco-friendly material.

As shown in Fig. 1, the present invention is characterized in that, as shown in Fig. 1, an additive including Illight, a polymer resin chip and a dispersant is compressed and crushed while passing through a mesh roller 20, Into a mixing and melting tank (31) through an outlet (31a)

The polymer resin chip coated with Il light and the remaining unlit light in the state not coated with the polymer resin chip and the additive were uniformly mixed through the high-speed stirring in the mixing and fusing tank 31, and the crushed polymer resin chips The mixed resin is melted by frictional heating to form a mixed resin in the form of a molten mixture of molten polymer resin, ilite and an additive, and discharged to an extruder 40. In the extruder, the mixed resin is passed through a lead screw 41 And then extruded, cooled, and cut while being transferred in one direction.

Here, it is possible to form a master batch chip containing 40 to 85% by weight of ilite and containing 10% by weight or less (excluding 0) of an additive including a dispersant.

In addition, the filament yarn containing ilite according to the present invention may be produced by mixing and molding a master batch chip containing a diatomite powder having a particle size of 1,000 to 2,000 mesh and a general polymer resin chip to prepare a filament yarn containing 1 to 10 wt% Or may be formed of a chip or an injection molded article.

Hereinafter, a process for manufacturing a filament yarn using a functional master batch chip containing Illight according to the present invention will be described in detail with reference to the accompanying drawings.

In order to manufacture the functional master batch chip containing ilite according to the present invention, firstly, a predetermined amount of differential from the one-light supply tank 11 and the resin chip supply tank 12, An olefin resin such as polypropylene (PP) or polyethylene (PE), a polyester resin such as polyethylene terephthalate (PET) or a polymer resin such as polyvinyl chloride (PVC), polystyrene (PS) Of chips and additives are supplied to the hopper (13).

Here, as the additive, wax is added as a lubricant in an amount of 5% or less of the total weight, and a fatty acid salt such as zinc stearate, calcium stearate, or magnesium stearate, Use 2 to 5% of the total weight. Therefore, according to the present invention, it is possible to maximize the content of the ilite and the polymer resin in the entire master batch chip using only 10 wt% or less of additive.

That is, in the present invention, as described later, since the surface area of the polymer resin chip is widened and fine unevenness is formed on the surface of the pressed polymer resin chip so that mixing with the uniform powder is uniformly performed, Only a small amount of the wax can be added, and therefore, the content of ilite can be dramatically increased as compared with the conventional technique using a large amount of wax.

On the other hand, the supplied Il light and the polymer resin chip are supplied from the hopper 13 through the discharge port 13a to the mesh roller 20 by self-falling, compressed by the mesh roller 20 and partially crushed, The surface area of the polymer resin chip is widened to form fine concavities and convexities on the surface of the polymer resin chip, and the diatomite powder is mixed with an additive such as a dispersing agent and wax to be applied widely and thinly on the surface of the pressed polymer resin chip, (30).

The mesh roller 20 not only widens the surface area of the polymer resin chip pressed by the irregularities of the surface of the roller but also prevents the materials from sticking to the surface of the roller during the pressing process, The master batch chip according to the present invention is manufactured using this type of roller since it is easy to apply and adsorb Il light by the unevenness.

The polymer resin chip to which the supplied unidirectional powder is applied enters into the mixing and melting tank 31 of the stirring section 30 and the upper stirring blade 32a of the stirring wing section 32 of the mixing and melting tank 31 ) Causes a swirling flow in the mixing and melting tank (31) to uniformly mix the remaining unirradiated powder and the polymer resin chips and additives not attached to the surface of the polymer resin chip, and the lower stirring blade (32b) The syringe and the polymer resin chip are rotated at a high speed to be stirred, and at the same time, the surface of the polymer resin is melted through the generated frictional heat, thereby performing a melting operation for achieving a state in which the polymer chips and the iridite powder are more uniformly mixed do.

In this way, the diatomite powder is uniformly applied to the surface of the polymer resin chip and discharged through the discharge port 31a in a predetermined amount. The flux is introduced into the extruder 40, heated and melted and uniformly discharged by the lead screw 40 Mixed, extruded, cooled and cut to complete a high-content master batch chip in which 40 to 85% by weight of ilite is homogeneously mixed with the polymer resin.

At this time, even when the extruder has a magnification of about 26 times, uniform mixing is performed. Therefore, time and energy savings can be expected compared with the conventional method using an extruder having a size of 36 or more.

2, in this embodiment, a plurality of irregularities 21A-a and 21B-a are formed on the surfaces of the driving roller 21A and the driven roller 21B to form irregularities 21A-a and 21B -a), the pulverizing action of the functional inorganic material and the polypropylene resin is more rapidly performed.

With this configuration, the functional inorganic material and the polypropylene resin which have fallen by self-weight by a predetermined amount through the discharge port under the control of the metering valve provided in the hopper portion and the polypropylene resin supplied to the crushing portion are crushed by the crushing roller composed of the driving roller 21A and the driven roller 21B (21).

On the other hand, the master batch chip containing ilite thus prepared is mixed with a general polymer resin chip and melted to be formed into a chip or an injection mold of a desired shape.

In the case of using as a chip or an injection molding, a master batch chip made of a daily light powder having a particle size of 1000 to 2,000 mesh is used, and a master batch chip of 4 to 20% by weight and 80 to 96% by weight of a general polymer resin chip, To thereby produce a chip or an injection molded product having a total amount of 1 to 10% by weight of ilite, and can be used as a highly functional eco-friendly fiber material. When spinning in the form of a filament fiber, consideration is given to the clogging of the spinning nozzle or the tensile properties of the yarn By mass of 4 to 20% by weight of a master batch chip containing ilite having a particle size of 3,000 mesh or more higher than that and 80 to 98% by weight of a general polymer resin chip, It can be utilized as a filament yarn used for a highly functional environmentally friendly garment.

Of course, it is also possible to produce a variety of secondary processed products by using an injection material containing filament, filament, etc.,
