Description

Method for manufacturing cosmetic cotton for cleansing or essence, and cosmetic cotton produced by the method {METHOD FOR MANUFACTURING MAKEUP COTTON USING CLEANSING OR ESSENCE AND MANUFACTURED MAKEUP COTTON BY THE SAME}

The present invention relates to a method for producing a cotton pad for cleansing or essence and a cotton pad manufactured by the method.

In general, the cleansing used to remove the makeup after the makeup is disclosed in various forms, such as a cleansing cream, cleansing oil, foam cleansing, cleansing gel, and the like, usually using a cotton pad.

In addition, the essence is disclosed as one of the basic make-up used in the make-up, and these kinds of essences are commercially available in various kinds, even if necessary, a cotton ball may be used.

In addition, it is good to use cotton as a material of such a cotton ball.

Cotton has a pure natural cellulose ratio of 90% or more, and the cellulose is repeatedly connected in a straight line to form chain cellulose molecules.

In particular, cotton has a hollow called lumen in the center of the fiber, and a microfibrel wall surrounding it, and the outer layer has a pectin-like wax component called cuticle, which also serves to withstand friction during fiber processing. do.

As such, cotton has a lumen because it is present, and when it is boiled, it is not only suitable for use as a cosmetic product because it is released when the lumen is opened while being heated, and it has the advantage of having no skin irritation at all.

In addition, cotton is excellent in impregnation due to the presence of lumens, and when used in a liquid state such as a lotion in a pouch or a container, there is an advantage that it can be used for a long time in a wet state.

Nevertheless, as cotton is a short fiber, it is easy to get lint, and because it is not compressible, it does not persist in the pressed state, so as shown in Korean Utility Model No. 0354973, the upper and lower portions of the cotton are wrapped in a thin nonwoven fabric for cleansing or essence The reality is making cotton balls.

In addition, even non-woven fabric itself makes a cotton, all of them can not be properly wiped due to the phenomenon of being pushed off when washing the face, because the hygroscopicity is inferior to cotton cleansing itself is not made completely.

In addition, there is a problem that causes skin problems in case of sensitive skin because the adhesive that is a chemical must be used to attach the nonwoven fabric to cover the surface.

In addition, when using them in a pouch or a container, only the lower side in contact with the liquid is kept in a wet state, and the upper side is easily dried, so there is a disadvantage in that there is no commerciality.

In addition, in the case of using cotton alone without a nonwoven fabric for surface covering, the cotton is scraped with a carding machine to make a thin sheet, or web, and sprinkled with resin or chemical when it is fluid in a state of overlapping. Since it must be processed in a form that enhances sincerity, it is harmful to the human body and has disadvantages in terms of environment.

Another method is to bind needles together using needle punching, but in the case of cotton, since the web itself is thin, this method is practically difficult and expensive, and this method is applied only to chemical fibers.

The present invention was created in view of the above-mentioned problems in the prior art as described above, and does not use a nonwoven fabric in a cover form, but has sufficient compressive strength only by cotton itself, has no lint, and has excellent hygroscopicity for cleansing or essence. The main object of the present invention is to provide a method for producing a cotton pad and a cotton pad prepared by the method.

The present invention as a means for achieving the above object, a carding process to form a web (Web) using a card machine scraping to make fibers from cotton; The web manufactured through a carding process is passed between the upper and lower water jet units installed in parallel with each other while maintaining a constant tension, and the single fibers constituting the web are vertically or randomly bound by a stream of water sprayed at high pressure. Waterjet processing process; A compression process of compressing the web in a state in which short fibers are bound to each other through a water jet processing process using a compression roll while maintaining a constant tension, thereby reducing the voids between the fibers and compacting them; The web compressed through the crimping process is processed to have a thinner edge than the face by using a processing roll, and at the same time, a portion of a logo, text, picture, or pattern is formed, and at the same time, a portion of the crimp is cut. It provides a process for producing a cleansing or essence cotton, characterized in that comprises a;

At this time, the web formed in the carding process is characterized by having a thickness of at least 3mm or more.

According to the present invention, cotton can be used for cleansing or essence by using cotton alone as a natural fiber, which is environmentally friendly, prevents skin trouble, and can obtain a suitable effect for use in a pouch or the like.

In addition, since there is no need to provide a separate non-woven fabric as in the conventional structure is simple and simple, easy to manufacture, low manufacturing cost, and can engrave logos, pictures, patterns, etc. can also obtain the advertising effect or aesthetics.

1 is an exemplary conceptual view showing a manufacturing example of a cotton ball according to the present invention.
2 is an exemplary perspective view of a cotton pad prepared according to the present invention.
3 is an exemplary cross-sectional view of a cotton pad prepared according to the present invention.

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

The cotton wool according to the present invention is made by processing the cotton in a spunlace method.

At this time, the spunlace method is a method that is already well known as a non-woven fabric processing method, for example, as well disclosed in the Patent Publication No. 2011-0008144, non-woven sheet made of short fibers (usually 'web (Web)) Refers to the manufacture of a rigid by spraying water at a high pressure on one side of the web through a waterjet to bind the short fibers to each other.

Such spunlace nonwoven fabrics are widely used, for example, as disposable diapers, medical nonwoven fabrics, and leather materials.

However, the nonwoven fabric bound in such a spunlace method has good elasticity in one direction, but lacks elasticity in the opposite direction, and thus has disadvantages in terms of form stability and mechanical properties, thereby limiting in terms of general purpose of use.

In addition to this reason, there were no examples of applying it to cotton, which is a natural fiber for various reasons. In particular, most of the natural fiber is a carding process for scraping a web through a carding machine, and a molding for adjusting the width and thickness required for the web. It is common to manufacture by a process, a bonding process for bonding using an emulsion, and a calendering process for fixing a form by applying heat, and all have been recognized that they can only be so processed.

However, the problems mentioned in the prior art focused on the need for more eco-friendly and efficient cosmetic cotton manufacturing technology, as a result of which the present invention was conceived.

In the manufacturing method according to the present invention, first, a carding process for forming a web through the card machine described above is performed.

The carding process is the same as the conventional one, it is one of the features of the present invention to be laminated at least a plurality of web to be maintained at least 3mm.

Here, the reason why the thickness of the web should be maintained at least 3 mm is because the spunlace method is applied to the cotton itself, and since it is squeezed in a subsequent process, the thickness of the web must be kept at least 3 mm to have the minimum strength. do.

The web thus formed is subjected to a waterjet processing process.

The waterjet processing process may be considered to simply adopt a spunlace method, but the first feature is that the spunlace method is not simply dedicated but applied to cotton, and cross-processes without interfering with each other on the top and bottom of the web. Is the second feature.

For example, as shown in FIG. 1, when the web is introduced into the entry tension roll 100 and passes through the exit tension roll 110, the web is tensioned.

At this time, the web is passed through the water jet unit installation space installed between the two tension rolls, the water jet unit is crossed with the lower water jet unit 210 and the lower water jet unit 210 is installed at a fine interval on the bottom of the web The water holes to be sprayed is made of the upper water jet unit 220 is arranged so as not to match each other, and the fine water stream is injected at a high pressure.

Then, among the myriad of short fibers constituting the web, the short fibers hit by the water stream sprayed from the bottom are directed to the top, and the short fibers hit by the water stream sprayed from the top are directed to the bottom, while the process passes through the unit. Repeating, the short fibers are entangled and sulky.

Accordingly, the cotton short fibers themselves have a significant binding force, and thus have a binding force between fibers similar to those of needle punching.

In this state, the web passing through the exit tension roll 110 performs a pressing process.

The pressing process is performed by a pair of upper and lower pressing rolls 120 which are installed after the exit tension roll 110. Since the web having a certain binding force is first pressed by a water jet, the pressing process is pressed below a predetermined thickness to have considerable rigidity. do.

At this time, the crimping degree of the web can be varied by adjusting the roll gap between the crimping rolls 120.

The compressed web is subjected to a processing process is processed to a predetermined shape via the processing roll (300).

The processing process using the processing roll 300 is well shown in the patent application filed by the applicant as of April 18, 2011 Patent Application No. 2011-0035506, so the detailed description is omitted, but briefly described as follows.

According to the above-mentioned patented technology, the present invention is equipped with a system capable of mass-producing cotton wool in a roll processing method, and it is obvious that there is workability and productivity since the device itself that enables it is commercially available.

The surface of the processing roll 300 is processed in the same shape as the shape of the cotton to be processed, but the edge of the cotton is compressed to have a thickness smaller than the thickness (D) of the surface portion 410 as shown in Figures 2 and 3 The processing rolls 300 are formed to protrude closer to each other so as to form the pressing portion 420, and a blade is installed on the upper processing roll along the edge, and an elastic skin is installed on the lower processing roll to correspond to the pressing. The cutting is configured to be made.

And, the face portion 410 of the cotton wool 400 is processed in the opposite shape corresponding to the corresponding portion of the processing roll 300 so that the company's logo, letters, pictures, patterns, etc. can be engraved or embossed.

Therefore, when the web passes through the processing roll 300, the pressing and cutting at the same time, and also the logo, patterns, letters, etc. are formed together.

In this case, decorative parts such as logos, patterns, and letters are not engraved, but are formed by a pressing method. Therefore, the roll gap between the processing rolls 300 should naturally be smaller than the initial thickness of the web.

Subsequently, the discharge roll 130 guides so that the cotton wool 400 is cut (preferably a type of perforation) and pulls the remaining residue to a winding roll (not shown).

As such, the cotton wool according to the present invention does not need to form a surface layer as a separate nonwoven fabric as before, and thus can use natural fibers as it is, and has excellent hygroscopicity, so that even when used in a pouch or a container with a lotion, the wettability is not dry or volatilized. It can be maintained for a long time has the advantage that it can be useful, environmentally friendly, and cheap to manufacture.
