Manufacturing method of synthetic fiber yarn using pozzolan

The method for producing a synthetic fiber yarn using the pozzolan of the present invention comprises the steps of 1) preparing a pozzolan dye containing pulverized pozzolan, 2) modifying the surface of the fiber yarn, and 3) And may include a step of salt-washing.

1 is a flow chart showing a method of producing a synthetic fiber yarn using a pozzolan according to an embodiment of the present invention.

Referring to FIG. 1, step 1) of the method for producing a synthetic fiber yarn of the present invention may be to prepare a pozzolan dye containing pulverized pozzolan (S100).

Specifically, the pozzolanic dyestuff comprises 5% to 8% by weight of the pulverized pozzolan, 1% to 3% by weight of a nonionic ester compound and 1% to 3% by weight of a cationic aromatic ester compound, % &Lt; / RTI > by weight. The nonionic ester compound may be highly dispersible, and the cationic aromatic ester compound may be highly homogeneous and highly transferable. The nonionic ester compound may be, for example, a propylene glycol fatty acid ester, a glycerin fatty acid ester, a sorbitan fatty acid ester, a polyethylene glycol sorbitan fatty acid ester, a polyoxyethylene sorbitan fatty acid ester, a polyoxyethylene glycerin fatty acid ester, Wherein the cationic aromatic ester compound is at least one selected from the group consisting of alkyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, stearyl trimethyl ammonium bromide, Or diethylaminoethylamide stearate, and the like, but are not limited thereto. According to an embodiment, water and an organic solvent may be further added to the pozzolan dye.

The pulverized pozzolan may be obtained by pulverizing natural pozzolans or commercially available pozzolans. The pulverization of the pozzolan powder in the form of a powder may facilitate mixing of the pozzolana with the fiber raw material by pulverizing the pozzolana into very small particles and increase the coloring power of the fiber yarn.

The pulverized pozzolan may be pulverized using a ball mill having a sieve size of 3 mu m to 10 mu m. A ball mill is a type of fine grinding machine that combines both impact force and frictional force. It is a device capable of grinding the grinding target material to a minimum particle size according to the size, quantity, or grinding time of the ball mill. The pozzolan can be pulverized to a uniform size by using the ball mill. The ball mill is not particularly limited as it can use a known ball mill apparatus.

The pozzolone pulverized by the ball mill may be used after being dried at a temperature of 80 ° C or more for 3 hours or more and then sealed to prevent contact with air and other substances, and then opened at the time of use.

Step 2) of the method for producing a synthetic fiber yarn of the present invention may be to modify the surface of the fiber yarn (S200).

The fiber yarn means a yarn to be a raw material of the synthetic fiber yarn of the present invention, and it is possible to use all kinds of fiber yarns of various materials according to the purpose of use. The fibrous yarn may be, for example, a natural fiber yarn or synthetic fiber yarn made from polyester, polypropylene, polyamide, acrylic, polyurethane, viscose rayon, or polytrimethylene terephthalate .

Specifically, the step of modifying the surface of the fiber yarn comprises the steps of exposing the surface of the fiber yarn using a first feed roller, a step of supplying water and air to the surface of the fiber yarn to modify it, And winding the modified fiber yarn on the winder by using the fiber yarn.

FIG. 2 is a schematic view illustrating a surface modification process of a fiber yarn according to an embodiment of the present invention.

Referring to FIG. 2, first, the surface of the fiber yarn can be exposed using the first feed roller 11 (S210). That is, the surface of the fiber yarn can be exposed to the reforming device composed of the water supply device 20 and the air supply device 30 by the first feed roller 11. It is possible to supply the fiber yarn continuously to the reforming apparatus through the first feed roller 11. To this end, the reforming apparatus may be provided with a plurality of thread guides, which can expose the surface of the fiber yarn while continuing to connect the fiber yarn. The first feed roller 11 has a scratch groove so that the fiber yarn is not tangled and the entire surface of the strand of the fiber yarn can be sufficiently exposed.

Then, water and air are supplied to the surface of the fiber yarn to modify the fiber yarn (S220). That is, the water supplied from the water supply device 20 can be supplied to the surface of the fiber yarn exposed through the first feed roller 11, and the air supplied from the air supply device 30 . The air supply device (30) is provided with a plurality of air injection openings for injecting air, so that strong air can be given to the fiber yarn. As described above, by imparting water and air to the fiber yarn, the elasticity of the fiber yarn can be improved. Specifically, the air can increase the bulky property of the fiber yarn, and the water is heated by the high-pressure air injected from the air supply device 30 to increase the friction force between the fiber yarns, Or may be supplied together with the air to inhibit degradation of the physical properties of the fiber yarn. As described above, the fiber raw material modified to have a bulky property can absorb the pozzolanic particle powders contained in the pozzolanic dye described later not only on the outer surface but also on the outer surface of the fiber yarn, so that the pozzolan dyeing efficiency can be improved .

Thereafter, the modified fiber yarn can be wound on the winder 40 by using the second feed roller 13 (S230). That is, in step S220, the modified fiber yarn having elasticity can be sequentially laminated on the winder 40 while maintaining the physical properties and shape of the fiber yarn through the second feed roller 13 have. The step of sequentially laminating the modified fiber yarn on the winder 40 may be performed in order to shorten the process time for defining the salt pouring with the pozzolan dye described later.

In one embodiment of the present invention, the winder 40 may be a soft winder in the form of a net. This may be to solve the problem that the fiber yarns are tangled with each other when the rewinder is used in a conventional drum type winder. In the above-mentioned mesh type soft winder, the modified fiber yarn is tightly wound in a net shape, so that the salt pouring with the pozzolan dye described later can be facilitated.

After the step of winding the modified fiber yarn into a winder, a dye transfer member may be disposed through the winder. A plurality of the dye transfer members may be arranged. The dye transfer member may be a cylindrical structure having a diameter of 0.02 mm to 0.03 mm for easy placement in the winder.

3 is a schematic view showing a dye transfer member disposed on a winder according to an embodiment of the present invention. Referring to FIG. 3, the dye transfer member may be arranged such that the pozzolan dye can easily penetrate the inner and outer portions of the fiber yarn wound around the winder to transfer the dye, in a pozzolana dye salt preparation process described later. The dye transfer member may be made of a material that does not affect the fiber yarn and the dye, and may be made of, for example, stainless, but is not limited thereto.

The step 3) of the method for producing the synthetic fiber yarn of the present invention may be such that the pozzolan dye is salt-modified to the modified fiber yarn (S300).

4A to 4C are schematic views for explaining the salt-poration of a pozzolan dye and a fiber yarn according to an embodiment of the present invention. 4A to 4C, the step of salt-fixing the pozzolanic dye to the modified fiber yarn comprises the step of pre-treating the modified fiber yarn (S310) disposed in the dyebath tank (S310) (S320 to S330) of adding the pH slide agent sequentially to the modified fiber yarn to increase the temperature of the dye bath to 110 ° C to 120 ° C to fix the pozzolan dye contained in the dyed fiber yarn S340), washing the fiber yarn to which the pozzolan dye is adhered (S350), and sequentially adding the coating agent and the fastness-increasing agent to the washed fiber yarn (S360).

4A is a schematic view showing a step S310 of pretreating the modified fiber yarn disposed in the dyeing bath. In S310, a refining agent is added to the modified fiber yarn to refine the modified fiber yarn or may be a process of scouring. The refining process may refer to a cleaning operation of the fiber yarn attached to the modified fiber yarn, such as removal of impurities which interfere with the dyeing and removal of dirt for uniform dyeing. Specifically, the preprocessing step (S310) is a step of preparing a dyeing tank to be subjected to dyeing, placing the modified fiber yarn in the dyeing tank, raising the temperature by 2 [deg.] C per minute, . Thereafter, a scouring agent may be added to the dyeing bath at a temperature of 70 to 80 ° C, refining the modified fiber yarn for 20 to 25 minutes, and then draining. At this time, the refining process can be performed in 10 minutes in in-out and 7 minutes in out-in.

The scouring agent means an agent for removing impurities in the fiber through actions such as wetting, penetration, emulsification, dispersion, bubbling and washing, and known scouring agents mainly used depending on the type of the fiber yarn can be used . Specifically, in one embodiment of the present invention, the scouring agent is used in an amount of 0.5 g / l to 0.7 g / l of a polyoxyethylene alkyl ether-based nonionic compound and 0.5 g / l of an anionic compound of a synthetic alcohol sulphate ester sodium salt- 0.0 > g / l. &Lt; / RTI > The polyoxyethylene alkyl ether-based nonionic compound has an excellent refining component and can impart hygroscopicity to the fiber yarn, and the anionic compound based on the synthetic alcohol sulfate ester sodium salt imparts uniformity to the fiber yarn .

FIG. 4B is a schematic view illustrating steps S320 to S350. In step S320, a pozzolan dye is added to a dyeing tank in which the pretreated fiber yarn is disposed to dye the pretreated fiber yarn. When the pozzolan dye is added, the temperature of the dyeing bath may be adjusted to 40 to 50 캜. That is, the dyeing process of the pretreated fiber yarn may be carried out in a dyeing bath to which the pozzolan dye is added, the temperature of which is within the above range. At this time, the pozzolan dye may be added using a known dosing apparatus. In one embodiment of the present invention, the step S320 may be performed by dyeing the pozzolan dye at a dose of 5 L / min. At this time, the dyeing process can be performed in in-out 10 minutes and out-in 7 minutes.

Referring to FIG. 4B, the step S330 is a step of sequentially adding a pH slid agent to the dyeing bath to which the pozzolan dye is added. In this case, the dyeing bath may be heated at a rate of 0.5 DEG C per minute so as to have a composition of 80 DEG C to 85 DEG C. That is, the dyeing process may be performed by adding a pH slider to the dyeing bath having a temperature within the above range. The step of adding the pH slurry may be performed by 3 times of dosing with 15 liters of pH slurry per minute. In one embodiment of the present invention, the pH slurry may be added in an amount of 1 g / l to 3 g / l, and further added with 0.7 g / l to 0.9 g / l of monophenyltin (MPT) . As described above, the dyeing bath can be maintained for about 50 minutes to about 60 minutes after the pH slide agent is added by the third dosing. The pH of the dyeing bath may be 5 minutes at the elapse of 10 minutes after the pH slide agent is added, and the pH at the elapse of 20 minutes may be 4 and the pH at 4 and 30 minutes may be 4. As described above, the change of the pH of the dyeing bath by adding the pH slide agent reduces the water solubility of the pozzolan dye by making the pH of the dyeing bath weakly acidic so that the dye penetrated into the fiber yarn is prevented from coming back to the dyeing bath . &Lt; / RTI >

Referring to FIG. 4B, the step S340 is a step of heating the dyeing bath to 110 to 120.degree. C. to fix the pozzolanic dye contained in the dyed fiber yarn. At this time, the temperature of the dye bath may be raised by 1 ° C per minute. By maintaining the dyed fiber yarn disposed in the dyeing bath at a temperature within the above range for about 70 minutes to 75 minutes, the pozzolan dye contained in the dyed fiber yarn can be fixed to the fiber yarn.

Referring to FIG. 4B, the step S350 is a step of washing the fiber yarn to which the pozzolan dye is adhered. The washing process can be carried out in the same manner as a conventional washing process of a fiber yarn. Specifically, it may be performed two times of cold water and one time of hot water of about 50 ° C, but is not limited thereto.

Then, a step of sequentially adding the coating agent and the fastness-increasing agent to the washed fiber yarn may be performed (S360). FIG. 4C is a schematic view for explaining the S360 process. Referring to FIG. 4C, the coating agent may be added to a dyeing bath in which the washed fiber yarn is disposed. The above-mentioned coating agent is not particularly limited as it can use a surface coating agent used in the production of ordinary synthetic fiber yarn. For example, the coating agent may be added with 0.5 wt% of 2303 binder, and the coating may be performed by 4 times of dosing, which is carried out at 20 L per minute. Thereafter, the temperature is raised by 0.5 ° C per minute to form a temperature of 70 ° C to 75 ° C, and then the temperature is maintained for 20 minutes to 25 minutes so that the coating agent can be easily coated on the surface of the washed fiber yarn have.

After that, it is cooled to 40 ° C to 45 ° C, and then the fastness-increasing agent is added. The fastness may be the color resistance of the dyed synthetic fiber yarn to the dyeing process of the dyed synthetic fiber yarn or its subsequent use. That is, after the dyeing of the washed cotton fiber yarn is completed by adding the color fastness improving agent, the coloring of the colored fiber yarn can be further improved. The fastness-increasing agent is not particularly limited as it can use any of the materials used in ordinary synthetic fiber production.

Thereafter, the temperature is raised by 0.5 ° C per minute to form a temperature of 70 ° C to 75 ° C, and the temperature is maintained for 20 minutes to 25 minutes so that the fastness enhancer can easily penetrate the surface of the washed fiber yarn . Then, by draining, a synthetic fiber yarn in which a pozzolan is dyed can be produced.

As described above, the method for producing a synthetic fiber yarn using the pozzolan of the present invention is characterized in that the surface of the fiber yarn is modified and the modified pozzolan dye containing the pulverized pozzolan is fused to the modified fiber yarn, And it is possible to improve the functionality of the synthetic fibers or clothes produced by using them.

Another aspect of the present invention provides a synthetic fiber yarn produced through the above-described method for producing a synthetic fiber yarn using the pozzolan. The synthetic fiber yarn is provided with antibacterial and deodorizing function of pozzolan by the pozzolana dyeing, and can be utilized for various fabrics.

5 (a) to 5 (b) are images showing the fiber yarn before and after the pozzolan dye dyeing, respectively. 5 (a) to 5 (b), it can be confirmed that the fiber source after the pozzolan dye dyeing uniformly dyes the pozzolan dye in the yarn, unlike before the dyeing, exhibits a peculiar color characteristic of the pozzolan dye.

Table 1 below shows the test results of the Korean clothing test institute against antibacterial activity of synthetic fiber yarn according to one embodiment of the present invention. From Table 1, it can be seen that the bacterium reduction rate of the synthetic fiber yarn of the present invention reaches 99.9% . Thus, it can be seen that the synthetic fiber yarn of the present invention has high antimicrobial activity.

Gloves containing synthetic fiber yarn

Another aspect of the present invention provides a glove comprising a synthetic fiber yarn produced by the above-described method for producing a synthetic fiber yarn using the pozzolan. That is, the glove may be a glove made of synthetic fiber yarn in which pozzolan is dyed. Accordingly, the glove may have antibacterial and deodorizing functions of the synthetic fiber yarn in which the pozzolan is dyed, so that the conventional antibacterial treatment process can be omitted. This may be an improvement of a complicated process of coating a coating surface on a glove surface in order to prevent desorption after coating a composition having antimicrobial function on the surface of gloves when manufacturing industrial gloves requiring conventional antibacterial and deodorization. In addition, since the synthetic fiber yarn itself has antibacterial and deodorizing function, the glove can be continuously used without deterioration in function even when used for a long time.
