④ Patent Registration No. 10-1353374 (published on Apr. 21, 2014) "Pest control and manufacturing method of antimicrobial fiber" is a method of manufacturing a fiber by infiltrating a liquid material extracted from lacquer and cinnamon having mosquito and insect- It is possible to combat various pests harmful to humans such as ticks and mosquitoes by means of lacquer and cinnamon ingredients penetrated into the fiber structure.
In the prior art described above, there has been disclosed a method of producing antibacterial fibers by vacuum depositing nanomaterials of various metals (especially Ag) in order to impart antimicrobial properties to a master batch or a chip, and then mixing the nanomaterials with a base material of synthetic resin fibers. It is difficult to control the mixing amount of the nanomaterial, and when the content of the inorganic nanomaterial is high, the material of the yarn is brittle, which makes it difficult to draw, which causes a problem of the manufacturing process and increases the production cost.
In addition, there is a shortcoming that the antimicrobial function is drastically lowered by washing the antimicrobial fiber product several times.
The present invention relates to a process for producing an antimicrobial polyolefin yarn containing an inorganic nanomaterial, in which a nano metal particle is deposited on a conventional master batch or a chip to produce an antimicrobial yarn, 90 to 97% by weight of a base material of a polyolefin-based synthetic resin yarn and 3 to 10% by weight of an inorganic nano material such as a nano metal or a metal oxide are mixed and homogeneously blended at a temperature of about 200 ° C to 250 ° C to form a fillet Mixing the nanomaterial into the base material of the yarn;
The yarns of the fibers spun by the spin dodger from the base material in which the nanomaterial is mixed are heated by the heating stretching rollers of 6 to 12 stages provided in the heating zone and the yarns of the yarns of the yarns A stretching step of the yarn in which the direction of the molecular chains of the fibers is fixed in the fiber axis direction by a heat setting box and a cooling box through a multi-stage stretching process under lubrication conditions; A high strength yarn having a strength of at least 10 g / den or more is produced in one step by a combination of two or more raw materials.
An object of the present invention is to provide a method for producing an antimicrobial and cold-sensible polyolefin-based high-strength yarn containing a cold-sensible nano metal having high antibacterial and thermal conductivity, or an inorganic nanomaterial such as a metal oxide, on a polyolefin yarn have.
Another object of the present invention is to provide a yarn containing nanomaterials in which the yarn is wound in a multi-stage heat-stretched yarn in a lubrication condition by a heating elongation roller of 6 to 12 stages installed in a stretching zone and an oil- The present invention provides a method for manufacturing an antimicrobial and cold-sensible polyolefin-based high-strength yarn in which the orientation of the molecular chains of the fibers is fixed in the axial direction of the fibers by a heat setting box and a cooling box to produce at least 10 g / .
Another object of the present invention is to provide a method of producing antibacterial and cold-sensible polyolefin-based high-strength yarn in which a fiber product made of a polyolefin-based yarn containing nanomaterials has hygienic safety by providing antimicrobial and cold sensory functions .
Another object of the present invention is to provide a method for producing an antimicrobial and cold-sensible polyolefin-based high-strength yarn in which the antibacterial and cold sensation functions are retained for a long period of time even if the fabric made of polyolefin yarn containing nanomaterials is repeatedly washed, .
The present invention relates to a method for producing an antimicrobial and cold-sensible polyolefin-based high-strength yarn, which comprises uniformly mixing an inorganic nano material such as a nano metal or metal oxide with a polyolefin- ; A stretching step of stretching the yarn radiated from the base material by a multi-stage heating stretching roll and fixing the orientation of the fiber molecular chains in the fiber axis direction; Lt; / RTI >
The mixing step of the inorganic nanomaterial to the base material of the yarn is carried out by mixing 90 to 93% by weight of the base material of the polyolefin-based synthetic resin yarn and 3 to 10% by weight of the nano metal or the inorganic nano- The materials are melted and mixed uniformly at a temperature of 200 ° C to 250 ° C and extruded into a fillet.
The nano-metal includes Zn, Cu, Mg, Ag, and Mn, and the nano-metal oxide includes Zn, CuO, CuS, and MgO, and any one selected from the nanomaterials is added to and mixed with the base metal.
In the present invention, the above-mentioned nanomaterials are used for antibacterial or thermal conduction. Therefore, the nanomaterials are not limited to the above-mentioned nanomaterials, and any inorganic nanomaterials having good antibacterial and thermal conductivity can be selected without limitation.
However, even a material having antimicrobial and cold sensation properties can not be selected as the antimicrobial or cold sensible filler of the present invention because the material that harms the sanitary property of the human body when it comes into contact with human skin is not suitable as a fiber product.
As the amount of nanomaterial added to the base material of the polyolefin yarn increases, the antimicrobial and cold sensibility of the yarn increases. On the other hand, since the physical properties of the yarn deteriorate, the yarn is affected by the stretching of the yarn. It is not preferable that the content does not exceed 10% by weight.
The stretching step of the yarn is a step of heating polyolefin yarns made of fibers spun by a high-speed spinning radiator from the base material containing the inorganic nano-materials to multi-stages by a heating stretching roller of 6 to 12 stages installed in a multi- And stretching at a high magnification while preventing the filaments from being disturbed by the emulsion of an oil supply device provided in the middle of the stretching simultaneous stretching zone.
Also, a plurality of filaments constituting the yarn are stretched at a uniform temperature while being heated while passing through the heating and stretching rollers while being in contact with each other in a stepwise manner. At this time, the speed at which the yarn passes through the stretching zone is 600 to 2000 m / min., And the yarn is stretched at a stretch ratio of 4 to 20 times in stages due to the difference in rotation ratio of the multi-stage stretching roller (high defect roller).
Since the yarn drawn in the stretching zone is forced to have a molecular chain orientation, when heat energy higher than the thermal energy supplied during the stretching of the yarn is applied in the process of producing the yarn and using the wig or the fiber product, So that the shape which contracts is generated. In this case, since the problem of deforming the original shape of the textile product occurs, the yarn enters the heat setting box in which heat energy higher than the thermal energy applied to the stretching of the yarn is distributed to prevent excessive contraction of the yarn.
The thermosetting box is equipped with a far infrared ceramic heater and blows hot air from the outside into the space inside the thermosetting box to prevent the temperature deviation in the thermosetting box to maintain a uniform temperature distribution simultaneously with heating, Thereby maintaining a temperature distribution.
The heat-treated raw material in the above-mentioned heat setting box enters the cooling box again and sufficiently cooled by cold air at 5 ° C to 10 ° C.
The yarn is produced in a consistent one-step process by moving the thermal setting box and the cooling box at the speed at which the yarn travels through the stretching zone.
Since the polyolefin-based high-strength raw material containing the inorganic nano material such as the nano metal or the metal oxide according to the present invention has a function of antibacterial and cold sensibility, the fiber product (glove, sock, sock, partition, tent, Other products) can feel cool due to the heat-dissipating action of nano-metal or metal oxide having good thermal conductivity in the yarn.
In addition, it can be sanitarily and safely worn by the antibacterial action of the nano metal or metal oxide contained in the yarn.
In addition, since the fiber product made of the yarn of the present invention is contained in the fiber without detaching the nanomaterial from the fiber even if it is washed a number of times, the antibacterial property and the cold sensation can be maintained for a long time.
The present invention relates to a method for producing a polyolefin-based synthetic resin yarn, which comprises mixing an inorganic nanomaterial into a base material of a yarn, mixing the inorganic nanomaterial such as a nano metal or a metal oxide in order to impart antimicrobial and cold sensibility to the base material of the polyolefin- A yarn of fibers spun from the base material by a high speed spinning dripping machine is stretched under the condition of a heating elongation roller of 6 to 12 stages installed in the stretching zone and an oiling agent of an emulsion feeding device provided in the middle of the stretching zone, The stretching of the yarn set by the thermal setting box and the cooling box to fix the molecular chain orientation in the axial direction of the fiber; The high strength yarn of at least 10 g / den (up to 12 g / den) can be produced more efficiently.
Further, since the yarn is provided with functions of antibacterial and cold sensation, various kinds of fiber products made of upper yarn can be used more hygienically and coolly.
Further, the fiber product made of the above yarn has various effects that it can be used more safely and usefully than the conventional ones, because the antibacterial and cold sensation functions are not lost even after washing several times.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is a block diagram of an embodiment of the present invention.
(S1) of mixing an inorganic nano material into a base material of a yarn in which an inorganic nano material such as nano metal, metal oxide, or the like is mixed with a base material of a polyolefin type yarn, and a step of stretching the yarn of the fiber radiated from the base material, (S2).
The mixing step (S1) of the inorganic nanomaterial to the base material of the yarn comprises mixing 1kg of the base material of the polyolefin-based synthetic resin yarn and 1kg of the nano-sized copper material in the mixer equipped with the heating means and the stirring means for imparting antibacterial and cold sensibility to the polyolefin- (Cu) powders are mixed and homogeneously melted and mixed at a temperature of 200 ° C to 250 ° C to extrude the base material of the polyolefinic yarn containing the inorganic nanomaterial into a granular fillet.
In the embodiment of the present invention, nano-sized copper (Cu) powder is selected as an antibacterial and cold-sensitive material. However, the present invention is not limited thereto and can be selected from nanomaterials such as Zn, Mg, Ag, Mn, MgO, and the like. The addition amount of the nanomaterial to the base material of the yarn is not limited to the above addition amount but can be adjusted.
If the amount of the inorganic nanomaterial added to the base material of the yarn is increased, the function of the antibacterial and cold sensation of the yarn is enhanced. However, since the physical properties of the yarn are brittle, it may adversely affect the drawing process. The addition amount may be set within a range not exceeding 10% by weight so as to maintain the balance.
As shown in Fig. 1, the stretching step (S2) of the yarn comprises a step (A) of spinning a fiber by a high-speed spindle spinning machine, a step of stretching the yarn of the fiber in a stretching zone (B) (C) for heat setting by a heat setting box for fixing the orientation and a cooling process (D) by a cooling box.
The apparatus used in the stretching step of the fiber used was a spinning spinning apparatus for producing pully-olefin-based high-strength yarn of Patent Application No. 2014-0132929 filed by the present inventor.
The fiber yarn discharged from the base material by the spin rod radiator through the fiber spinning process (A) is stretched at a high magnification rate through the stretching process (B) in the stretching zone. In the heating zone, two sets of heating and heating rollers are arranged in three rows and three columns. In addition, two emulsion feeders are provided at a certain interval in the middle of the stretching zone to supply the emulsion to the yarn so that the filament can be stretched.
The running speed of the yarn passing through the stretching zone was adjusted to 1700 m / min, and the yarn due to the difference in the rotation ratio of each stretching roller was stretched at a stretch rate of 6 to 20 times in a stepwise manner.
The molecular spin orientation of the originally spun fibers is somewhat disordered, but the heating temperature in the stretching process is set at a temperature higher than the glass transition temperature so that the molecular chain orientation is oriented in the fiber axis direction through the stretching process, To move freely.
In order to prevent excessive shrinkage of the raw yarn after the stretching process, the yarn is subjected to a heat treatment process (for example, a heat setting process) in which a thermal energy higher than the thermal energy applied to the stretching of the yarn is distributed C) was added.
The heat setting box of the yarn has a built-in far-infrared ceramic heater, which emits high heat. At the same time, high-temperature hot air is blown from the outside to maintain the temperature distribution uniformly and the temperature of the heat setting is adjusted to about 270 ° C. higher than the drawing temperature.
The raw yarn heated through the heat treatment step (C) was then subjected to finishing so that the physical properties of the yarn were fixed through the cooling treatment step (D) by a cooling box so that the molecular chain orientation of the fibers was fixed in the fiber axis direction.
The internal temperature of the cooling box is uniformly distributed with cold air of 5 ° C to 10 ° C.
Therefore, the molecular chain orientation of the yarn subjected to the heat treatment process by the high temperature is fixed by the cooling process of the cooling box to obtain a high strength polyolefin yarn of up to 12 g / dem.
Evaluation of the sensitivity of the fiber is cold yeoldeon nor Q MAX and the lower limit of the value to evaluate the Q MAX value and recognize the cold sensitivity is 0.22J / sec / ㎠ is reasonable and Q MAX value of 0.20J / sec / ㎠ or more 0.22 J / sec / cm < 2 >
The Q MAX value is the simulated body temperature that is taken to the sample when the garment is worn. The larger the Q MAX value, the higher the body temperature taken at the time of garment.
In addition, the indirect measurement of contact coldness measures the thermal conductivity, and cold sensation generally felt to be cool should not be more than 1 x 10 -3 ℃ / W m2.
Here, the thermal conductivity is measured by superimposing a sample to be measured on a hot plate, stabilizing the temperature of the hot plate to a predetermined temperature, measuring the heat loss rate, and calculating by the following equation.
Thermal conductivity * W / Cm / 占 폚) = W x D / A /? T.
W = heat flow rate (j / sec),
D; The thickness of the sample,
A: Heat plate area (㎠)
The results of measurement of contact coldness and antimicrobial activity using a measuring instrument and measuring method using a 12 g / den antimicrobial and cold sensory yarn-woven glove specimen prepared according to an embodiment of the present invention were evaluated extensively.
As a result of the evaluation, the thermal conductivity was found to be 2,2x10 -3 ° C / W m2, and it was confirmed that the cold sensation was excellent. Also, the antibacterial activity was tested by the bacterial culture method, and the antibacterial activity was 99.9%.
Since the molecular chain orientation of the fiber product manufactured by the yarn of the present invention is fixed, the molecular chain orientation of the yarn is not dispersed by washing or ironing when various kinds of fiber products are manufactured, so that the original shape of the product is maintained.
In addition, when the fiber product according to the present invention is worn, heat of the skin is radiated by the heat conduction of the nano-metal contained in the yarn, and it is felt cool.
In addition, since nanoparticles are highly antimicrobial, they can be more hygienically sanitized by inhibiting the propagation of various bacteria harmful to the human body, which is parasitic on the fiber products, and by killing them.
Also, even if repeatedly washed repeatedly, the function of antimicrobial activity and cold sensation are maintained, and the safety and usability of hygiene are guaranteed.
