Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a process for producing a cellulose acetate sheet, and a process for producing the same. 2. The cellulose acetate sheet as claimed in claim 1,

The present invention relates to a dye-resistant composition for processing various color designs on a cellulose sheet to which a cosmetic ingredient of a mask pack is applied, and a method of processing a cellulose sheet using the same.

Cosmetic mask pack is a kind of functional cosmetic product that restores the skin physiological function by effectively removing the dirt of the pores and effectively supplying moisture and cosmetic ingredients to the skin by wrapping the active substance on the face.

There are various types of sheets to which the cosmetic component of the mask pack is applied. Among them, the nonwoven fabric type that can be thinly manufactured in recent years is a nonwoven fabric type which is made by cutting a thin nonwoven fabric into a face shape, It is packaged and easy to use.

The nonwoven fabric, which is often used as a sheet of the mask pack, is formed into a felt shape by arranging short fibers in parallel or in a negative direction without going through a woven process. The raw material fibers include cellulose, Fiber is mainly used.

In the conventional mask pack, a white nonwoven fabric not coated with a color has been used. Recently, as the mask pack market has become active, various methods of applying design elements by adding a color to a nonwoven fabric have been proposed.

For example, Korean Utility Model Registration No. 20-0470948 discloses a mask pack including an entertaining face image printed on a front face of a mask body in a real size, and Korean Patent No. 10-1536890 discloses a mask pack Discloses a mask pack that brightly illuminates a luminous image in a dark place with a shape image similar to a face of various characters such as a person, an animal, and the like. At this time, images and the like are printed on a sheet such as a nonwoven fabric with a oil-soluble ink or printed using an ultraviolet curing ink.

In the production of a mask pack printed with an image and the like, dyeing a nonwoven fabric of a cellulose material, which is a natural material, does not exhibit high fastness, so that a method of dyeing a nonwoven fabric made by mixing a polyester material and a cellulose material And the color was implemented.

However, since the nonwoven fabric of the polyester base material has poor skin adhesion and solution-containing properties, the color expression of the whole product is inferior to that of the skin, and when the polyester base material contains a large amount of polyester base material, There is a problem that the affinity is low, and the dye remaining in the cellulose-based material has a problem that the fastness is lowered.

   ≪ / RTI >

The above-mentioned mask pack cellulose sheet is not particularly limited as long as it is a basic sheet of a mask pack impregnated with a liquid cosmetic preparation and is a sheet containing cellulose. Nonwoven fabrics made of plant cellulose fibers of cotton or pulp type, and supports made of biocellulose made by culturing microorganisms. Preferably, a nonwoven fabric of 50 g / m ² to 70 g / m ³ is used.

The pigment is not particularly limited as long as it is used for cellulose-based fiber printing. Typically, pigments such as triarylmethine pigments and xanthene pigments; Azo pigments such as soluble azo pigments, insoluble azo pigments and condensed azo pigments; Phthalocyanine pigments; And a condensed polyanhydride pigment; Titanium dioxide, zinc sulfide, zinc oxide, iron oxide, manganese iron oxide, chromium oxide, ultramarine, nickel or chromium antimony titanium oxide, cobalt oxide, mixed oxides of cobalt and aluminum, rare earth sulfides, bismuth vanadate, And a mixture thereof.

In this case, the content of the pigment is preferably 0.01 to 10% by weight in the printing ink composition. If the content of the pigment is less than the above range, the coloring effect is insignificant. On the contrary, when the content of the pigment exceeds the above range, the bonding fastness and the rubbing fastness are lowered and the fixation fastness Lt; / RTI >

Since the pigment has no affinity for fibers, it is necessary to use a binder to dye the fibers. Accordingly, in the present invention, a polyacrylate-based polymer binder is used which binds to cellulose fibers to physically adhere the pigment to the fibers to uniformly color the fibers.

The polyacrylate-based polymer binder is preferably used as a binder composition mixed with a nonionic surfactant and water. This binder composition comprises 7 to 15% by weight of a polyacrylate-based polymer binder, 3 to 4% by weight of a nonionic surfactant, 3 to 8% by weight of an oily solvent, 2 to 5% by weight of a fixing agent, 2 to 3% By weight to 65% by weight, and is preferably used as the remainder of the print hide composition excluding the pigment. If the binder composition is less than the above range, the adhesive strength of the pigment to the fibers during printing is lowered. On the other hand, if the binder composition is in the above range, the viscosity of the printed sealing composition is increased and the workability is deteriorated.

The polyacrylate-based polymeric binder is a polymer and / or a block copolymerized polymer mainly composed of an acrylic group. Examples of the binder include one kind of hydrophilic monomer selected from the group consisting of acrylic acid, methacrylic acid, acrylonitrile, methacrylonitrile, acrylamide, and blends thereof, C ₁ -C ₁₀ alkyl (meth) acrylate, Aryl (meth) acrylate, and a blend of these monomers.

If the content of the binder is less than the above range, the adhesive strength of the pigment to the fibers will be lowered in the case of printing, and conversely, , There is a problem that the viscosity of the printing ink composition is increased and the workability is lowered.

The nonionic surfactant may be selected from the group consisting of alkylphenol ethoxylates, polyoxyethylene alkyl ethers, polyethylene glycols, polypropylene glycols, and mixtures thereof. At this time, the content of the nonionic surfactant is preferably 3 to 4% by weight in the composition for printing. If the content of the nonionic surfactant is less than the above range, the effect of addition is insignificant. On the other hand, when the content of the nonionic surfactant exceeds the above range, coloring of the pigment is disturbed, The alkylphenol ethoxylate may be an alkylphenol ethoxylate having an ethoxy group of 8 to 20. For example, the alkylphenol ethoxylate is nonylphenol ethoxylate, octylphenol ethoxylate, or derivatives thereof.

The oily solvent acts smoothly on squeezing and is used to maintain the continuity of the day with the function of delaying the drying phenomenon on the plate surface of the formed plate of the design. For example, kerosene, solvesso 100, or solvesso 150 are possible. In this case, the content of the oily solvent is preferably 3 to 8% by weight in the composition for the printing salt. If the content of the oily solvent is less than the above range, the workability is lowered. On the other hand, The function of the adhesive wax adhered to the wax is weakened, so that the process of moving the wax is deteriorated due to separation and development of the fabric at the end of the wax.

The above fixing agent acts to improve the smooth touch feeling and fastness of color fastness of the knot design and uses a mixture comprising N-methyl-2-pyrrolidone, polydimethylsiloxane, polyethylene glycol tridecyl ether and polyurethane .

In this case, the fixing agent is preferably 2 to 5% by weight in the printing ink composition. If the amount is less than the above range, the flexible fastness tends to fall and the touch feeling and the color fastness to fastness become poor and the normal quality can not be obtained. If the usage is above the above range, the soft touch feeling may be deteriorated and the quality of the product may be deteriorated.

The binder composition uses water as a solvent, and the content of water is appropriately controlled within the range of 65 to 84% by weight in the composition of the printing ink considering the viscosity and the workability of the printing composition and the binder composition.

The thickening agent is added so that the pigment is printed on the fiber and then is clearly adsorbed without spreading to the periphery. For example, methylcellulose, carboxymethylcellulose, hydroxyethylcellulose, sodium polyacrylate, polyvinyl alcohol, sodium polystyrene sulfonate, and the like are possible.

The content of the thickener is preferably 2 to 3% by weight of the composition. If the content of the thickener is less than the above range, the pigment tends to spread when it is printed. On the other hand, The viscosity of the emulsion composition is increased and the printing workability is lowered, and the thickener is excessively deposited on the fibers, which makes pigment complexation difficult.

The above-mentioned seal flame retardant composition is used for the mask material cellulose sheet processing.

1 is a flow chart of a method of processing a mask material cellulose sheet using the dye-resistant composition according to the present invention.

Referring to FIG. 1, a method of processing a mask material cellulose sheet

S1) preparing a mask material cellulose sheet fabric;

S2) passing the fabric composition through the fabric;

S3) drying the passed fabric; And

S4) morphological stabilization of the dried fabric

.

Each step will be described in more detail below.

First, in step S1), a mask material cellulose sheet fabric is prepared.

At this time, the sheet fabric may be a nonwoven fabric made of plant cellulosic fibers of cotton or pulp type, or a support made of biocellulose produced by culturing microorganisms. Prepare the fabric to be conveyed to the fabric adhesive belt for printing machine scaling while being stretched at a constant speed and at a constant speed.

Next, in step S2), the fabric is passed through the fabric.

The printing salt composition immediately replaces the above.

It is designed by using various tools (computer, etc.) considering the pattern to be given to the target fabric separately from the preparation of the printing hose composition.

Once the design for the target material is determined, prepare a flat screen plate or a rotary screen plate. The printing filing composition is knitted using a manual knitting machine, a flat screen automatic knitting machine or a rotary screen automatic knitting machine. Specifically, when the fabric and the belt are separated, the wax is applied to the surface of the circular rotary plate of the screen. After checking whether it is a suitable copper plate mesh according to the shape of the design to be passed, fix it to each unit, attach magnesium steel for the proper scaling, and a thrust rod, adjust each color so that it runs correctly, Inject the arcs. At this time, adjust the pressure of the squeezing bar and the moving speed of the fabric so that the penetration of the back of the fabric is minimized.

Then, in step S3), the knitted fabric is dried.

It is necessary to set the optimum drying temperature for the conveyance of the fabric and the prevention of shrinkage of the fabric according to the running speed. This is because the thickness of the nonwoven fabric layer is thin due to the use of the mask pack, so that it shrinks when the temperature is higher than the proper temperature. Also, when the drying speed is faster than the feed speed in the course of transporting the fabric, This is because the knife design of the mask pack is deformed rather than the expected shape, resulting in a defective product.

It is preferable that the fabric is dried at a speed of 30 m / min to 50 m / min at a speed of 35 m / min to 40 m / min, and the drying temperature is preferably 130 ° C. to 160 ° C. The fabric exiting through the dryer is wound on a roll beam or received in a moving bogie. At this time, make sure that there is no deformation of the kneading design.

Finally, in step S4), the shape stable processing is performed.

It is important to adjust the length and width of the nonwoven fabrics so as to achieve the expected sputtering design standard. The optimum temperature and processing speed should be maintained.

Preferably, a tentering process is performed for morphological stability processing. The term " tentering " refers to a process of fixing the shape of a knitted fabric so that the knitted fabric is not deformed by washing while thermally processing the same with a predetermined tension. For this purpose, in the present invention, the knitted fabric is wound on a roll, ).

That is, in the present invention, the dried fabric is wound on a cylindrical roll, and the tenter having an internal temperature of 140 to 160 ° C is passed through the pneumatic system at a speed of 40 to 60 m / min for 30 to 90 seconds do.

Using the roll beam at the exit of the process, confirm that the shape of the kneading design is the desired size, and wrap the finished nonwoven fabric so that the outside is wrapped with plastic wrap to prevent contamination.

Through the processing method of the present invention, various colors can be imparted to a cellulose sheet as a natural material with a high degree of fixation, and a soft touch feeling, a deep color feeling, and a shape stability can be exhibited.

Hereinafter, preferred embodiments of the present invention will be described in order to facilitate understanding of the present invention. However, the following examples are provided only for the purpose of easier understanding of the present invention, and the present invention is not limited by the examples.

Using the cellulose nonwoven fabric (50 g / m ² ), the processing according to the present invention was carried out using the printing hose composition of Table 2 above.

Specifically, according to the prepared design, an ink-jet dyeing composition was applied using a rotary screen automatic kneader. Thereafter, the fabric was dried at a drying rate of 35 m / min at 140 DEG C, and then subjected to a forming process at 150 DEG C for 1 minute using an 8-chamber tenter.

(Comparative Example 1)

The procedure of Example 1 was repeated except that water was used instead of kerosene and fixing agent in the binder composition of Table 1 above.

Experimental Example  1: Check skin irritation

A mask pack prepared by impregnating the mask pack materials of Example 1 and Comparative Example 1 with the serum of the following Table 3 was applied to 20 female subjects in their twenties to thirties, and the pack was removed after 20 minutes. After the experiment, the sensory evaluation of the degree of sensation by the subjects was evaluated based on the 5 - point scale and averaged. However, when the evaluation was performed on a 5-point scale, the score was evaluated as 5 points when the satisfaction was high, and 1 point when the satisfaction was lower, and the results are shown in Table 4

division  Content (% by weight) 1,3-butylene glycol  5 glycerin 3 Triethanolamine 0.05 Distilled water 86.1 ethanol 5 Tocopheryl acetate 0.2 Metal paraben 0.15 PEG-40 Hydrogenated Castor Oil 0.5 gun  100

Item Experimental Example 1  Comparative Example 1 Skin irritation 4.5 3.1

As shown in Table 4, the mask pack made of the cellulose sheet processed with the printing salt composition of the present invention had little skin irritation. This indicates that the pigment is closely adhered to the sheet so that the pigment has a good fixation by the printing salt composition and does not induce irritation to the skin, and other ingredients contained in the printing salt composition show little irritation to the skin.

Experimental Example  2: Washing Fastness  Confirm

The Wash Fastness Test is a test to determine the degree of color change and dye transfer to other fibers when the dye is washed with incomplete dyeing during dyeing.

First, the cellulose sheet of Example 1 and Comparative Example 1 was impregnated with the serum of Table 3 and stored at room temperature for 3 days. After that, it was visually confirmed whether or not the pigment was eluted.

The cellulose sheet of Example 1 and Comparative Example 1 was placed in water at 90 占 폚 and stored at room temperature for 3 days. After that, it was visually confirmed whether or not the pigment was eluted.

As a result, the cellulose sheet of Example 1 had no color change in both the serum and the high-temperature water, but in the case of the cellulose sheet of Comparative Example 1, the pigment was eluted into the serum and hot water. That is, since the printing hide composition of the present invention is excellent in washing fastness, it can prevent skin irritation due to mite migration.
