Description

Dyeing method of mask lining using ultrasonic waves and mask manufactured by this method {Dyeing Method of using ultrasonic waves for non-woven fabric and the mask containing the same}

The present invention is for manufacturing a natural dyed mask, and more specifically, a method for dyeing a mask lining using ultrasonic waves to prevent antibacterial and skin troubles in contact parts of the human body due to long-time use by natural dyeing on the lining of the mask, and this method It is to provide a mask made of.

In general, masks are used for cold weather masks to block cold air from entering and to prevent fine dust in the air from entering the human body through the respiratory system or harming others due to air leaks such as cold viruses. It is used separately for medical or health purposes.

In addition, as a threat to our health and life, more serious than diseases caused by viruses are antibiotic-resistant bacteria, which are resistant to antibiotics among bacteria and are ineffective with existing antibiotics. As a result, lifestyle and quarantine guidelines are changing, and the need for more hygienic, functional, and antibacterial materials that are safe for the human body is also emerging.

Recently, the use of masks has been increasing in order to prevent or treat repeated viruses and bacteria, and has now become an essential element of life.

Korean Registered Patent No. 10-2078504 discloses a medical or health mask. The mask includes a mask body covering the user's mouth and a left hanging band and a right hanging band for hooking and fixing the mask body to the user's ears. At this time, by adjusting the length of the left hanging band and the right hanging band, the mask body can be brought into close contact with the user's face.

Conventional masks have low rigidity because only the circumference is bonded while the non-woven fabrics are separated from each other, so contamination occurs as the inner surface of the mask comes into contact with the mouth and nose, resulting in skin trouble on the part that comes into contact with the human body during long-term use or in the mouth and nose during breathing. There was a problem with breathing being uncomfortable while being closely attached.

It is a flow chart showing a mask lining dyeing method using ultrasound according to an embodiment of the present invention.

Hereinafter, the present invention will be described with reference to the accompanying drawings. However, the present invention can be embodied in many different forms, and is therefore not limited to the embodiments described herein.

Throughout the specification, when a certain component is said to "include", it means that it may further include other components without excluding other components unless otherwise stated.

Preferred embodiments of the present invention will be described in detail together with the drawings to the extent that those skilled in the art can easily practice them in the technical field to which the present invention belongs.

It is a flow chart showing a mask lining dyeing method using ultrasound according to an embodiment of the present invention.

The mask lining dyeing method using ultrasonic waves of the present invention includes a natural dye input step (S100), a dyeing step (S200), a drying step (S300), a spraying step (S400), and a winding step (S500). In the mask lining dyeing method using ultrasonic waves, a natural dye is uniformly dyed by ultrasonic waves on a mask lining in contact with a human body from fabric, and the permeability of the antibacterial mordant can be improved. In addition, the dyeing method of the present invention can be directly applied to the existing production process, and has an effect of removing powder appearing in natural dyeing and shortening the heating time by using heating ultrasonic waves.

In the step of adding the natural dye (S100), the powdered natural dye and the mordant are mixed with the solvent ethanol (25%), and the dissolved solution is then added to the molten metal. The solution is first dissolved by stirring using a magnetic for 1 to 2 minutes at a temperature of 45 ~ 55 ℃ after mixing the natural dye and the mordant in ethanol. The first dissolved solution is put into the molten metal through a filter. At this time, the filter allows only the solution that has passed through the filter in the middle region to be injected into the molten metal because the natural dye floats in the solvent due to the difference in specific gravity in the first dissolved solution and the mordant erodes under the solvent. The filter is characterized in that 10% of the upper and lower sides are blocked and pores of 2 to 6 μm are formed in the middle region. The filter has an effect of removing powder that appears in natural dyeing by first removing insoluble powder from the dissolved solution and then injecting only the dissolved solution into the molten metal.

The natural dye is characterized in that it is an antibacterial material through natural dyeing (gardenia, turmeric, bamboo charcoal, somok, omija, pomegranate, Gaza, etc.) using natural substances harmless to the human body.

In the dyeing step (S200), the dye is uniformly dyed using heating ultrasonic waves and the mordant is uniformly penetrated into the fabric. The dyeing step (S200) is dyed for 1 to 2 minutes at a temperature of 35 to 45 ° C. using microbubbles using heating ultrasonic waves. In the dyeing step (S200), a smooth penetration effect can be obtained even if the amount of dye and mordant used is reduced using ultrasonic waves. In addition, since the dyeing step (S200) can reduce the amount of dye and mordant using ultrasonic waves, economic effects can be obtained by reducing material costs.

In addition, the dyeing step (S200) is dyed by relaxing the tissue of the fabric (non-woven fabric) by a cavitation phenomenon accompanied by chemical and thermal actions due to micro-agitation and destruction of bubbles according to the negative pressure effect of ultrasonic waves and the vibration of tens of thousands of bubbles. and enhances mordant penetration. In addition, in the dyeing step (S200), micro bubbles are generated due to the vibration of bubbles caused by cavitation through ultrasonic waves to cause a stirring action to promote a chemical reaction, and bubbles are formed by the wavelength of the bubbles. Uniform dyeing and mordant effect can be obtained by the principle of accelerating the chemical reaction due to the thermal action by increasing the pressure and temperature of the dye.

In the drying step (S300), the dyed fabric is dried with hot air. In the drying step (S300), the dyed fabric is transferred through a roller, and a hot air fan at 35 to 45° C. is provided between the rollers transporting the fabric and the roller to dry the fabric. At this time, the hot air blower is to remove the dyeing powder remaining on the fabric at the same time as drying. In addition, the drying step (S300) of drying using the hot air machine has the effect of shortening the overall dyeing process time by shortening the drying time.

In the spraying step (S400), natural dye is sprayed onto the lining of the dried fabric. The spraying step (S400) is applied by spraying using a spray at a temperature of 35 to 45 ° C. for dyeing color and antibacterial uniformity of the fabric.

In the winding step (S500), after the spraying step (S400), the fabric is dried and stored after being rolled along with the rolling transfer. In the winding step (S500), the fabric is dried using near-infrared rays (at 40° C. for 1 minute).

As described above, the mask manufactured by the method of dyeing the mask lining using ultrasonic waves of the present invention is naturally dyed on the lining of the fabric, so that antibacterial and skin troubles can be prevented in the human body contact area.

In addition to this, the description of the present invention described above is for illustrative purposes, and those skilled in the art will understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. You will be able to. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.

The scope of the present invention is indicated by the following claims, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention.
