In addition, the method of manufacturing a protective clothing textile material for removing harmful chemicals according to an embodiment of the present invention, by using a process using a padding facility that is easy to operate, it is possible to ensure productivity, manufacturing technology of protective clothing material Can contribute to the localization of

According to one aspect, the pick-up rate of the reactive nano-catalyst particles for the fiber material may be 200% or more.

According to an embodiment of the present invention, a method for preparing a protective clothing textile material for removing harmful chemicals may include preparing appropriate solids and padding process conditions of a preparation capable of maximizing adhesion amount of hazardous chemical decomposition reactive nanocatalyst particles to the fiber material. By optimizing, the pick-up rate for the fiber material of the reactive nanocatalyst particles is realized at 200% or more, thereby realizing a protective clothing fiber for removing chemicals having an excellent effect of removing harmful chemicals.

According to one aspect, the fiber material, may be a nonwoven fabric.

According to one aspect, the fibrous material comprises at least one selected from the group consisting of polypropylene nonwovens, activated carbon fibers, lightweight polypropylene, needle punched nonwovens, and multilayered composites thereof It may be.

Fabrics used for general apparel have a lower surface area than nonwoven fabrics, so that the content of catalysts is limited. In fact, when the padding process using a fabric material, the pick-up rate is only about 60% to 80%, which is disadvantageous to show the performance of the catalytic material. On the other hand, among many nonwoven fabrics, especially needle punching nonwoven fabrics, needle needles are reciprocated up and down to combine two-dimensional fibers in a three-dimensional random structure to increase the strength of the nonwoven fabric and to support a large amount of catalyst material. It may have an advantageous structure to implement a pick-up% (200% or more).

Test by type of textile material

Table 1 is a table comparing catalyst loadings after the padding process for each fiber material type.

* ACF: Activated carbon fiber

* PP: Polypropylene Nonwoven

* PAN: Polyacrylonitrile

Referring to Table 1, when using a general PAN-based carbon fiber fabric, it was confirmed that the pickup rate is less than 100%, whereas in the case of the PP nonwoven material needle-punched through a hydrophilization treatment, a high content of catalyst was supported. It can be seen that the glass (pickup rate of 200% or more). In addition, when the needle punched nonwoven fabric material is processed again in a multilayered composite form, it can be seen that the amount of catalyst loading is greatly increased, and the performance as a protective suit can be maximized.

It can be seen from Table 1 that the pick-up amount immediately after passing the mangle during the padding process is greatly influenced by the internal voids of the fiber material. The pick-up rate of activated carbon fiber (ACF), which is known to have a surface area of more than 1000 m ² / g, was the highest at 341%, whereas the PAN-based carbon fiber was 84%. The PP nonwoven fabric showed high pick-up rate of more than 200% in both single and multi-layer composite forms. However, in the case of calendered fabric of PP nonwoven fabric, it can be seen that the volume is relatively small compared to general PP nonwoven fabric and the pores are reduced, which is disadvantageous in securing the amount of preparation.

According to one aspect, the harmful chemicals are bis- (2-chloroethyl) sulfide, pinacolyl methyl phosphonofluoridate, ethyl N, N- Dimethylphosphoroamido cyanidate (ethyl N, N-dimethylphosphoroamidocyanidate), isopropyl methylphosphonofluoridate, trichloronitromethane, O-ethyl S- (2-diisopropylamino Ethyl methylphosphonothioate (O-ethyl S- (2-diisopropylamino) ethyl methylphosphonothioate) and derivatives thereof may include at least one chemical agent selected from the group consisting of.

According to one aspect, the harmful chemicals may be at least one selected from the group consisting of neuro- and vesicular agents.

According to one aspect, the reactive nanocatalyst particles, MOF-808, UiO-66, UiO-66-NH ₂ , UiO-67, UiO-67-NH ₂ and MIL-100 (Fe) at least selected from the group It may be to include one.

The protective clothing fiber for removing harmful chemicals according to the present invention forms a metal-organic skeleton and thus has a specific surface area, and by applying reactive nanocatalyst particles capable of expressing all catalytic properties using metal ions, The substance can be decomposed all under different environmental conditions. In addition, by applying the reactive nano-catalyst particles, it is possible to implement a protective clothing fiber for removing harmful chemicals that can be rapidly absorbed or adsorbed while contaminating chemical agents.

According to one aspect, the solids content of the dispersion containing the reactive nanocatalyst particles may be from 10% by weight to 30% by weight.

According to one aspect, the viscosity of the dispersion containing the reactive nanocatalyst particles, may be from 261 cPs to 460 cPs.

Solid content and viscosity of the catalyst material used in the padding process are important factors in selecting the working conditions as well as the dry add-on of the fabric after the treatment. The amount of pick-up may vary depending on the pressure of the mangle during padding, but the part due to the difference in physical properties of the preparation itself is large.

If the solid content of the dispersion containing the reactive nanocatalyst particles exceeds 30% by weight, there is a problem that the padding process is impossible, if less than 10% by weight, the pickup rate may occur.

When the viscosity of the dispersion containing the reactive nanocatalyst particles exceeds 460 cPs, the solidification of the preparation due to the volatilization of the solvent is accelerated, a large amount of dust may occur, the viscosity is less than 261 cPs due to the low content of the preparation solids There may be a problem that the removal performance of harmful chemicals of the post-treated protective clothing material is degraded.

According to one aspect, the dispersion containing the reactive nanocatalyst particles, may include a reactive nanocatalyst particles, ethanol and water.

According to one aspect, the weight ratio of ethanol and water included in the dispersion containing the reactive nanocatalyst particles may be 1: 1 to 1: 3.

If only ethanol is used as the dispersing solvent, it may cause damage of the mangle feather and fire occurrence during drying. Therefore, it is preferable to use a dispersion containing reactive nanocatalyst particles, ethanol and water.

Dispersion Content Test

Table 2 is a table comparing the catalyst loading of the fiber material according to the content of solids, ethanol and water contained in the dispersion.

In order to use the solid UiO-66-NH ₂ nanocatalyst in the padding process, it is necessary to disperse it in a solvent and to disperse it in ethanol. However, when only ethanol was used as the dispersing solvent, the test was carried out to select an appropriate content ratio for the actual padding process by using water additionally in consideration of damage of the mangle padder and the occurrence of fire during drying. In particular, when the dispersion is exposed to air due to the nature of the UiO-66-NH ₂ catalyst, solidification proceeds rapidly. As the solid content increases, this phenomenon becomes more severe, resulting in non-uniformity of catalyst particles due to solidification during a long time of padding, and consequently, weight variation of parts of the treated fabric may occur. In the present invention, in order to ensure both the maximization of the preparation content and the minimization of the solidification of the preparation was tested for each solvent content. When the solid content was more than 30% by weight level, it was observed that the solidification proceeded within 9 minutes after the padding operation. That is, the optimum solids content of the preferred UiO-66-NH ₂ catalyst may be 20% by weight.

According to one aspect, the step of padding the fibrous material in the dispersion containing the reactive nanocatalyst particles, may be performed at a mangle (Mangle) pressure of 1 bar to 3 bar. More preferably, it may be performed at a mangle (Mangle) pressure of 2 bar to 2.5 bar.

By adjusting the pressure of the mangle during the padding operation, the pick-up rate (or pick-up amount) of the hazardous chemical decomposition catalyst on the fiber material can be controlled.

When the pressure of the mangle is less than 1 bar, a problem may occur in that the weight variation of each part of the treated fabric may be uneven due to an uneven amount of the pick-up preparation in the fiber material, and the pressure of the mangle is 3 bar. If it exceeds, the pick-up (Pick-up) is reduced to the fiber material of the processing aid, there is a fear that the fabric is damaged when using a thick fabric.

In the case of the nonwoven fabric material which is applied as a preferred example of the textile material of the present invention, the thickness of the fabric itself is thicker and wider pores than the fabric, it is advantageous to support a high content of catalyst particles, but the desired mangle pressure ( Mangle pressure from 2 bar to 2.5 bar).

Test by padding condition

In addition to the type of fiber material, the mangle pressure is a factor that may affect the amount of pickup of the preparation when the fiber is padded. The pressure conditions are padded at 2 bar and 2.5 bar, which are workable levels in the field, and the pickup rates are shown in Table 3 below.

If the mangle pressure is more than 3 bar, the pick-up rate loss is large, so it proceeds up to a maximum of 2.5 bar pressure. On the contrary, if the mangle pressure is less than 1 bar, there is a gap between the mangles depending on the weight variation of the fabric or the thickness of the fabric material. The minimum pressure was chosen as 2 bar because it may occur. Especially in the case of non-woven fabric composed of three layers of PP-ACF-PP, this phenomenon is more prominent, and it is impossible to proceed with work due to leakage of preparation when the fabric passes between mangles. Referring to Table 3, when the PP non-woven fabric is used alone, the mangle pressure of 2 bar, when using a multi-layer composite form of PP and ACF it can be seen that 2.5bar pressure is appropriate.

According to one aspect, the step of drying the fiber material padded in the dispersion may be performed at a temperature condition of 120 ℃ to 160 ℃.

In order to remove the solvent of the fabric immersed in the padding process, drying at an appropriate temperature should be carried out. In the case of the PP nonwoven fabric used in the present invention, since the melting point is lower than that of general materials such as PET or cotton, care should be taken when selecting temperature conditions. . Too high a drying temperature causes deformation of the fiber whose main component is PP, and a low drying temperature causes the nonwoven fabric containing a large amount of processing liquid to remain undried after dipping.

According to one aspect, the step of drying the fiber material padded in the dispersion, which is carried out in a number of cut or continuous steps, the first drying step carried out at a temperature condition of 145 ℃ to 160 ℃; A second drying step carried out at a temperature condition of 130 ° C. to 145 ° C .; And a third drying step performed at a temperature condition of 120 ° C to 130 ° C.

According to one aspect, the step of drying the fiber material padded in the dispersion may be performed through a plurality of drying chambers.

Padding-drying equipment according to an embodiment of the present invention is preferred that the drying chamber is composed of seven compartments, the temperature conditions of each chamber can be set separately. Considering that the Tm of PP is about 160 ° C., chambers 1 to 3 were selected as 150 ° C., chamber 4 was 140 ° C., and chambers 5 and 7 were 125 ° C. to proceed with the process. Although it was concerned about the damage of the fiber due to the high temperature condition during drying, as soon as a large amount of liquid picked up to the nonwoven fabric immediately after being immersed in the processing liquid, the effect of the drying hot air directly on the PP nonwoven fabric can be offset.

According to one aspect, the antimicrobial processing step of the fiber material; may further include.

According to one aspect, the dispersion containing the reactive nanocatalyst particles, may further comprise an antimicrobial agent.

According to one aspect, the step of antimicrobial processing of the fiber material, may be carried out by a dust reduction method before the step of padding the fiber material in the dispersion containing the reactive nano-catalyst particles.

According to one aspect, the antimicrobial treatment of the fiber material, may be performed at the same time as the step of padding the fiber material in the dispersion containing the reactive nano-catalyst particles.

Antibacterial Processing

In order to establish the manufacturing method of protective clothing material which has both antimicrobial and harmful chemicals removal performance, the antimicrobial activity was verified by treating the fabric by process type and antimicrobial agent content. For the fabric sample, PET (Polyethylene terephthalate) white cloth fabric was used, and the catalyst and the antimicrobial agent were treated simultaneously with the pad cure method and the antimicrobial agent was first treated with the exhaust method, followed by the padding treatment of the catalyst. The antimicrobial activity was changed according to the manufacturing process. Mangle pressure during the padding process was treated in 2.5 bar, speed 2.5 m / min, 1 dip-1 nip method. In the case of the dust reduction method, the general PET fiber dyeing process conditions were applied, and then treated at 130 ° C. for 30 minutes and then dried at 140 ° C. for 90 seconds. The contents of the preparations used in each preparation method are shown in Table 4 (content of preparations used in the Pad cure method), Table 5 (content of preparations used in the Exhaust-Pad cure method) and Table 6 (results of antimicrobial test).

Referring to Tables 4 to 6, both samples showed a bacteriostatic reduction rate of 99.9% or more, and there was no difference in antimicrobial performance according to the preparation method. It was confirmed that the antimicrobial performance was maintained in both the padding method of treating the catalyst and the antimicrobial agent in the same bath, and the fabrics produced by sequentially treating the antimicrobial agent and the catalyst by the dust reduction method and the padding method, respectively.
