As can be seen from the case of the FOSHAN leakage accident that became a social issue in recent years, a chemical leak accident occurring in the industrial site may cause serious danger not only to the operator but also to the environment around the industrial site.
On the other hand, workers at industrial sites who are directly exposed to the risk of chemical spillage are generally working with reliance on detection systems such as chemical leak detectors installed in the work area.
Therefore, when a chemical detection system installed at an industrial site is broken or malfunctioned, there is a problem that workers are exposed to the risk of chemical leakage.
Accordingly, an object of the present invention is to provide a nonwoven fabric for chemical detection, which can effectively detect the leakage of chemical substances in an industrial field, and enable a worker at an industrial site to quickly recognize the leakage of a chemical substance, And a work wearer to which a nonwoven fabric for chemical detection is attached.

Preferably, the step (a) includes the steps of: impregnating the nonwoven fabric with a solution in which the water absorbent is dissolved; And drying the nonwoven fabric impregnated in the solution.
The step (b) may further include spraying the chemical detection reagent onto the nonwoven fabric.
Meanwhile, the nonwoven fabric for detecting a chemical substance according to the present invention comprises a nonwoven fabric to which a water absorbent is bonded; And a chemical detection reagent coated on the nonwoven fabric.
Preferably, the water absorbent is bonded to the nonwoven fabric by drying the nonwoven fabric impregnated in the solution in which the water absorbent is dissolved.
Meanwhile, the work wearer according to the present invention is characterized in that the chemical-detecting nonwoven fabric is attached to the outer skin.
INDUSTRIAL APPLICABILITY According to the present invention, there is provided a nonwoven fabric capable of effectively detecting leakage of a chemical substance in an industrial field.
In addition, according to the present invention, a work wearer is provided which enables a worker at an industrial site to quickly recognize the leakage of a chemical substance.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a flow chart for explaining a process for producing a nonwoven fabric for chemical detection according to an embodiment of the present invention, and Fig.
FIG. 2 is a flowchart illustrating a process of using a nonwoven fabric manufactured by the method for producing a nonwoven fabric for chemical detection according to an embodiment of the present invention.
Hereinafter, the present invention will be described in detail with reference to the drawings. It is to be noted that the same elements among the drawings are denoted by the same reference numerals whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart illustrating a process for producing a nonwoven fabric for chemical detection according to an embodiment of the present invention. FIG. Referring to FIG. 1, a method of manufacturing a nonwoven fabric for chemical detection according to an embodiment of the present invention will be described. First, the manufacturer dissolves a water absorbent in distilled water to a saturated concentration (S110).
In carrying out the present invention, it is preferable to use calcium chloride or the like as a material capable of absorbing moisture in the air as the water absorbent.
On the other hand, the nonwoven fabric used in the practice of the present invention may preferably be a PE nonwoven fabric having excellent chemical resistance. Then, the manufacturer impregnates the saturated calcium chloride solution with the nonwoven fabric (S130), and after the impregnated nonwoven fabric is taken out from the saturated calcium chloride solution, the drying treatment is performed (S150).
In carrying out the present invention, in performing the drying process on the nonwoven fabric in the above-described step S150, the manufacturer may use a hot air drying process or a microwave drying process.
By performing the drying treatment on the nonwoven fabric impregnated with the saturated solution of calcium chloride, if the water of the saturated solution of calcium chloride is completely evaporated, the calcium chloride powder remains bonded to the fibrous particles of the nonwoven fabric.
On the other hand, in step S150, the manufacturer applies a chemical detection reagent such as a BTB solution to the nonwoven fabric having been subjected to the drying process, thereby applying the chemical detection reagent to the nonwoven fabric (S170).
In order to prevent the BTB solution from being absorbed by the calcium chloride powder bonded to the nonwoven fabric, the BTB solution may be impregnated with a nonwoven fabric As shown in FIG.
Next, the manufacturer performs drying treatment as quickly as possible (S190) before the water of the BTB solution is absorbed by the calcium chloride powder bonded to the nonwoven fabric (S190), thereby completing the production of the coated nonwoven fabric with the chemical detection reagent such as BTB .
FIG. 2 is a flowchart illustrating a process of using a nonwoven fabric manufactured by the method for producing a nonwoven fabric for chemical detection according to an embodiment of the present invention. Referring to FIG. 2, the process of using the nonwoven fabric manufactured by the method for producing a nonwoven fabric for chemical detection according to an embodiment of the present invention will be described. The manufacturer uses a chemical such as BTB in the state where the water absorbent powder such as calcium chloride is combined The nonwoven fabric coated with the substance detection reagent is detachably attached to the outer surface of the work wearer's work such as work clothes, work gowns, work shoes, work gloves, and work toys worn by a worker at the operation site (S210).
On the other hand, the operator performs work in a state in which the non-woven fabric manufactured according to the present invention is worn on the outside and wears an acidic substance such as phosphoric acid, hydrofluoric acid, sulfuric acid or an alkali substance such as potassium hydroxide, ammonium hydroxide The leakage of the chemical substance can be recognized through discoloration of the nonwoven fabric attached to the outside of the wearer's worn spout (S230).
Specifically, since the water absorbent powder such as calcium carbonate, which is bonded to the fibrous structure of the nonwoven fabric produced according to the present invention, has a property of absorbing moisture in the air, it is possible to prevent the chemical substance To the nonwoven fabric.
As a result, even a very small amount of chemical substance can be smoothly supplied to the nonwoven fabric due to the hygroscopic action of the water absorbent powder bonded to the fibrous structure of the nonwoven fabric, and the discoloration of chemical detection reagent such as BTB coated on the nonwoven fabric The operator can recognize the leakage of the chemical substance early.
On the other hand, after recognizing the leakage of the chemical, the worker who has moved to the safe place removes the non-woven fabric contaminated with the chemical material from the worn work worn by the user (S250) It can be reused without being discarded.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
Furthermore, the terms used in the present invention are used only to describe specific embodiments and are not intended to limit the present invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the terms "comprises" or "having" and the like are used to specify that there is a feature, a number, a step, an operation, an element, a component or a combination thereof described in the specification, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.
