In general, in the case of functional fibers containing natural substances, natural fibers such as ganbanite, jade, germanium, ocher, charcoal, etc., which have such a function, are added to dye fibers or liquid coating the woven fiber surface. Functional fibers were formed.

However, these functional fibers have a problem that the functional material is difficult to fully adhere to or absorb the fibers or yarns, so durability is reduced, and the original functionality does not continue as the number of washing increases.

Therefore, the present invention was conceived in view of the above point, to form a master batch pellet mixed with finely powdered sulfur and synthetic resin, and to mix the master batch pellet with a synthetic resin through a process such as melt spinning The purpose of the present invention is to provide an antimicrobial yarn and a method of manufacturing the same, which maintains the physical properties of the synthetic yarn itself and has excellent stability as an antimicrobial agent and have a long antibacterial activity.

Here, the master batch pellet forming step or mixing step further comprises a pigment, the synthetic resin is one of polyester, polypropylene, nylon, the sulfur powder is preferably 1 ~ 3㎛ particle size.

In the present invention, by forming an antimicrobial agent containing a synthetic resin, by mixing the antimicrobial agent with a synthetic resin to form a mixture, and melt spinning the mixture to form a basic yarn, in the antimicrobial yarn formed through the cooling and stretching process, The mixture is 70 to 85 parts by weight of synthetic resin, 10 to 20 parts by weight of sulfur powder, 5 to 10 parts by weight of polymer-based dispersant and 0.3 to 1 part by weight of antibacterial agent formed by mixing 85 to 90 parts by weight of synthetic resin The antimicrobial yarn formed by mixing is made into a technical subject matter.

Accordingly, by forming a master batch pellets containing sulfur powder and synthetic resin having an antibacterial effect, and mixing the master batch pellets with a synthetic resin to form a yarn through a process such as melt spinning, the stability of sulfur as an antimicrobial agent is excellent And, there is an advantage that the antimicrobial activity lasts for a long time.

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

1 is a process chart showing the antimicrobial yarn manufacturing method according to the present invention, Figure 2 is a process chart for forming a master batch pellets.

As shown, the antimicrobial yarn manufacturing method according to the present invention is largely composed of the master batch pellet forming step, mixing step, the basic yarn manufacturing step, the cooling step and the stretching step.

First, the master batch pellet forming step will be described.

The master batch pellet forming step is formed by melting and stirring in a stirrer by adding a sulfur powder, a polymer-based dispersant and an antioxidant to a synthetic resin consisting of polyester, polypropylene, nylon. Here, if necessary, a pigment may be added in the master batch pellet forming step.

That is, about 10 to 20 parts by weight of ultrafine sulfur powder pulverized to 1 to 3 µm with respect to 70 to 85 parts by weight of the synthetic resin in the form of particles, 5 to 10 parts by weight of a polymer-based dispersant, and a pigment 5 to produce color. 10 parts by weight and 0.3 to 1 part by weight of antioxidant are mixed in a stirrer to form a mixture, followed by stirring in a state in which the temperature in the stirrer is about 20 ° C to 30 ° C.

When the high-speed stirring in the stirrer, the synthetic resin generates frictional heat by mutual friction, the frictional heat is generated on the surface of the synthetic resin, the powdered sulfur powder and the polymer dispersant are evenly mixed In the method of attaching to the surface of the synthetic resin is a synthetic resin surface is coated with sulfur and a polymer-based dispersant in the form of powder.

In the above state, the mixture is transferred to an extruder and melt-extruded at a temperature of about 150 ° C to 220 ° C, cooled to 70 ° C to 80 ° C in a cooler, dried in a dryer, and formed into pellets by cutting in a cutter. do.

That is, the antimicrobial agent containing sulfur is formed in a pellet shape in the master batch pellet forming step.

Next, the mixing step is performed, the mixing step of mixing the antimicrobial pellets formed in the master batch pellet forming step with a synthetic resin composed of one of polyester, polypropylene and nylon to form a mixture and stirring, the master batch pellet If the synthetic resin is nylon at the time of forming the synthetic resin is mixed, the synthetic resin is mixed if the synthetic resin is polyester at the time of pellet formation proceeds in a manner that the polyester is mixed.

The mixing ratio of each material is mixed so that the synthetic resin is about 80 to 90 parts by weight with respect to 10 to 20 parts by weight of the pellet, which is an antimicrobial agent, and mixed in a stirrer to complete the mixing step.

In the above, the pigment for producing color was described as being added in the master batch pellet forming step, but the pigment addition may be made in the mixing step and is within the scope of the present invention.

That is, in the master batch pellet forming step, the synthetic resin, the sulfur powder, the polymer dispersant and the antioxidant are mixed in the same ratio as the embodiment in the master batch pellet forming step, and the same process to form a pellet of the antimicrobial agent, and mixed In the step, 10 to 15 parts by weight of the antimicrobial pellet, 80 to 90 parts by weight of the synthetic resin, and 2 to 7 parts by weight of the pigment are mixed to form a mixture and stirred in a stirrer.

Here, in the mixing step, when the sulfur component is excessive, when producing the final antimicrobial yarn, that is, the problem that the antimicrobial yarn is short-circuited in the stretching step to be described later occurs.

Next, the basic yarn manufacturing step is performed, and the basic yarn is formed by melt spinning the mixture mixed in the mixing step at a temperature of about 180 ° C to 260 ° C. Coarse thread is formed before this and the foundation yarn is subjected to a cooling step.

The cooling step proceeds by cooling the basic yarns formed and output in the basic yarn forming step at a temperature of 15 ° C. to 30 ° C., which is to prevent mutual attachment of the basic yarns to each other. Since is a known technique, further description will be omitted.

Next, the stretching step is performed, the antimicrobial yarn produced by the process of stretching the basic yarn cooled in the cooling step to a length of 2 to 6 times at a temperature of about 20 ℃ ~ 160 ℃ to produce an antimicrobial yarn as the final yarn wound It is wound up.

The antimicrobial yarn formed in the stretching step is woven or knitted using a loom, knitting machine, or the like to be made of socks or final fibers.

The antimicrobial yarn according to the above configuration is excellent in stability as an antimicrobial agent by forming a yarn by adding sulfur powder having antimicrobial activity from the step of forming the yarn, and the antimicrobial activity is long lasting.

The present invention by the above configuration, by adding a sulfur component having an antimicrobial component from the basic step of forming a yarn to form a yarn, while maintaining the physical properties of the fiber itself, the sulfur component can be maintained for a long time and durable even when washing It is effective to maintain.

In addition, since the sulfur component is contained in the yarn itself in the form of particles, there is no need to undergo a separate antimicrobial treatment process, thereby reducing the number of processes according to the production of the product.
