[0001] VINTAGE FABRIC [0002] BACKGROUND OF THE INVENTION [0001]

The present invention relates to a method of processing vintage fabrics and a method of processing the same, and more particularly, to a method of processing vintage fabrics and methods of processing vintage fabrics by coating the fabric and rubbing the coating layer ≪ RTI ID = 0.0 > fabrics. ≪ / RTI >

In general, clothes such as jeans or fabrics made of various surfaces have recently been decolorized partially on the surface of the fabric to produce a feeling that the fabric is worn and dull.

In general, natural leather has been widely used in various industrial fields such as clothes, bags, and shoes, and the consumption thereof is gradually increasing. However, leather products made of natural leather are expensive, have a disadvantage in that they require a lot of effort and cost in washing and maintenance, and in recent years, demand for artificial leather fabrics has been increasing as a substitute for natural leather fabrics.

Artificial leather used as a substitute for natural leather is ahead of natural leather in easiness of washing, improvement of dyeing fastness, antibacterial property, stability, prolongation of life due to abrasion resistance, elasticity and touch. However, in addition to improving living standards, consumers are demanding artificial leather with improved texture and a variety of feelings, depending on the ever-changing trend of fashion. In order to satisfy such a consumer's desire, recently, a chemical is supplied to the surface of a fabric, and the paper is pressed by a roller, followed by drying and ironing, and then by abrading a part of the coating layer by friction, A method of manufacturing a fabric that gives a suede feel has been disclosed.

However, in the conventional method of manufacturing a suede-like fabric, since the pressing is performed by using a roller in a coating process for applying a medicine, problems such as elongation of the fabric or turning of the fabric on the left and right sides frequently occur. Especially, it is more difficult to apply medicines in case of thin cloth. In case of using coarse mesh rollers, when the medicines are applied on the fabric and the rollers are pressed, the fabric does not absorb the medicines and the medicines are pushed by the pressure of the rollers And if you want to re-coat the coated chemicals with different colors. If you use the roller in the conventional way, you will not be covered finely because the mark is left in Mongolia Mongolia, There was a disadvantage to this.

As a technique to be a background of the present invention, there is Korean Utility Model Registration No. 0296050 entitled " Pattern Processing Apparatus for Friction of Fabric Surface "(Patent Document 1). In the background art, there is provided an inflow guide roll 4 and an outflow guide roll 5 for moving a fabric wound on a fabric roll, and a processing part 10 installed between the inflow guide roll and the outflow guide roll 1. A pattern processing apparatus for forming a pattern by abrading a forming roll (14) and a friction roll (12) on opposite sides to each other and abrading a fabric moving to a center of the forming roll (14) And a vibrating device (50) installed at one side of the friction roll (12) to vibrate the friction roll in the axial direction.

However, since the above-described background art works by applying friction by the friction roll 12, the pattern to be rubbed is not natural, and a certain pattern is repeated, which is unnatural.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate exemplary embodiments of the invention and, together with the description, serve to explain the principles of the invention, Shall not be construed as limiting.
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a process drawing schematically showing a method of processing a vintage fabric according to the present invention. Fig.
2 is a cross-sectional view of a vintage fabric of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

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

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a process drawing schematically showing a method of processing a vintage fabric according to the present invention. Fig.

As shown in Fig. 1, in the method of processing a vintage fabric of the present invention, first, the fabric 1 to be processed is prepared (a).

The fabric preparation step may be a general pretreatment step of preparing the fabric to be processed in a state where the fabric is not stained or refining, drying and dyeing the fabric, and may be carried out by a known method.

The fabrics to be processed may be nylon, nylon and cotton knitted fabrics, or various known fabrics such as cotton, and knitted fabrics, knitted fabrics, and knitted fabrics may be used.

Then, 10 to 70 parts by weight of aqueous acrylic and / or aqueous polyurethane are mixed with 100 parts by weight of water to prepare a coating solution (b).

The fabric (1) may have a cold and hard texture. A separate coating solution is prepared to apply a coating liquid to the fabric to convert the fabric into a soft, moist powder texture and to produce a high-quality fabric.

As the main material of the coating liquid used in the present invention, it is possible to use only water-based acrylate, only aqueous polyurethane, or a mixture of water-based acrylic and aqueous polyurethane.

The polyurethane has the effect of imparting a function of surface protection and water repellency by forming a fine pore or a water repellent film upon coating on the fabric. The acrylic resin has a strong feeling on the surface of the fabric 1 to improve the texture of the surface, Thereby protecting the surface of the substrate 1.

The coating liquid of the present invention may be prepared by mixing 10 to 70 parts by weight of aqueous acrylic and / or aqueous polyurethane at room temperature on the basis of 100 parts by weight of water, particularly by mixing using a drum type mixing apparatus equipped with a propeller.

When water is used in an amount of less than 10 parts by weight, the effect of volume control and surface protection is deteriorated. If the mixing ratio exceeds 70 parts by weight, the coating layer becomes thick and the surface of the fabric is peeled off smoothly during friction processing. appear.

Further, 10 to 15 parts by weight of an additive such as wax may be further mixed.

The wax has a function to impart a smooth feel and a sense of volume, and the polyurethane has the effect of imparting functionalities such as surface protection and water repellency by forming a fine pore or water repellent film upon coating on a fabric.

When the additive such as wax is mixed in an amount of less than 10 parts by weight, the surface of the fabric does not show a volume feeling or a smooth texture. If the additive is added in an amount exceeding 15 parts by weight, the wax particles may irregularly fall off during rubbing.

The precise mixing ratio of the components constituting the coating solution was determined by forming a number of control groups with different ratios, and then performing the processing method according to the present invention. The memory effect, water repellency, surface texture, It is the optimum ratio value calculated by comprehensively comparing the results of the additional post-processing of garment washing.

The coating liquid 21 thus prepared is supplied to the impregnation tank 2 of a predetermined size in a predetermined amount so that the fabric 1 can be impregnated in a subsequent process.

Thereafter, the raw fabric 1 is impregnated into the impregnation tank 2 to supply the coating liquid 21 to the raw fabric 1 (c).

The impregnation tank 2 is prepared on the other side of the prepared fabric 1 and the fabric 1 is continuously supplied to the impregnation tank 2 so that the coating liquid 21 can be sufficiently absorbed into the fabric 1, (1) is impregnated into the coating liquid (21).

The raw fabric 1 is moved past the coating liquid 21 in the impregnation tank 2 so as to be continuously fed from the one side of the impregnation tank 2 to the other side, One or more rollers 25 may be provided in the impregnation tank 2 so as to facilitate the movement of the impregnation tank 2. The roller 25 may be formed in a zigzag form The fabric 1 is impregnated into the coating liquid 21 for a predetermined period of time while passing through the plurality of rollers 25 so that the coating liquid 21 is sufficiently supplied to the fabric 1. [

Thereafter, a supporting roller 32 is formed on the other side of the impregnation tank 2 at the lower part of the roller 31 and the roller 31. After the fabric 1 is impregnated into the impregnation tank 2, (D) so that the coating liquid 21 is uniformly absorbed on the surface of the fabric 1 by penetrating between the support rollers 32.

An excess amount of the coating liquid 21 is deposited on the surface of the raw fabric 1 because the raw fabric 1 passes through the interior of the coating liquid 21 filled in the impregnation tank 2 as in the step (c) .

Accordingly, in this step, the coating liquid 21 supplied to the fabric 1 is removed in an excessive amount, and the coating liquid uniformly applied is applied uniformly.

For this reason, on the other side of the impregnation tank 2, a supporting roller 32 is formed under the roller 31 and the roller 31 and impregnated in the coating liquid 21 of the impregnation tank 2 for a certain period of time The extruded raw fabric 1 is passed through between the roller 31 and the receiving roller 32 to pressurize the coating liquid 21 supplied to the raw fabric 1 in an excessive amount so as to squeeze the coating liquid 21, 1).

Thereafter, the fabric 1 with the coating liquid 21 fixed on its surface is dried in the heat chamber 4 to remove moisture at a temperature of 80 to 200 ° C (e).

In this step, the fabric 1 coated with the coating liquid 21 is dried by a heat drying method. There are various methods such as thermal drying, hot air drying and steam drying in general drying method, but thermal drying method is used in order to minimize curing of the coating liquid and damage of the fabric (1). It is desirable to dry in the thermal chamber 4 at a temperature of 80 to 200 캜 so that about 90% of the moisture is removed. If the temperature in the heat chamber 4 is lower than 80 ° C., the drying time becomes too long. If the temperature is higher than 200 ° C., the drying is too short in a short period of time and the chemicals are blown away. The fabric 1 is preferably poured into the heat chamber 4 which generates heat at 150 to 170 ° C., and is gradually passed through to allow the coating liquid to be absorbed and dried.

Finally, the surface of the coated fabric 1 is abraded by friction (f).

The method of working a vintage fabric of the present invention can cause the surface of the fabric 1 to be rubbed by various methods,

In the friction process, dry friction using a primer and a dumbbell, and wet friction using water to friction or wash can be used.

It is desirable to use a wood-based primer which generates frictional heat of low temperature so that the coating layer on the surface of the fabric fabric surface used for dry friction is appropriately abraded.

The dumbbell can be dried using a variety of known products.

Wet friction is caused by friction between the water and the fabric (1) while rotating the fabric (1) in a washing machine, or by spraying water directly on the fabric (1) by spraying method. The fabric is then dehydrated by a dehydrator, It can be dried.

Further, in the present invention, an ironing step may be additionally provided between steps (e) and (f).

the fabric 1 dried in the step (e) may be pressed between the heat roller 51 and the receiving roller 52 at a temperature of 130 to 150 캜 to heat and press the fabric 1 to coat the fabric 1.

In this ironing step, the dried fabric 1 is passed between a heat roller 51 at a temperature of 130 to 150 DEG C and a support roller 52 made of a rubber material, and is heated and pressed again. As a result of the ironing step through the heat roller 51, about 10% of the moisture remaining in the fabric 1 is completely dried and a glossy coating layer is formed on the surface of the fabric.

The supporting rollers 32 and 52 located at the lower ends of the rollers 31 and the heat rollers 51 must be made of rubber so as to elastically support the fabric when pressure is applied from the upper rollers good.

2 is a cross-sectional view of a vintage fabric of the present invention.

In the friction step of the present invention, the primordium used in the leather factory is the same as that used for the leather care, and is a barrel having a diameter of about 3 m. It is made of iron, but the coating layer 11 on the surface of the non- In order to wear, it is preferable to use a wooden base (6) which generates frictional heat of low temperature.

The coated fabric 1 is cut into a length of 20 to 50 m to be wound into a primer so as to prevent the fabric 1 from being entangled in the rotating primer, So that a worn pattern 12 is formed, giving the fabric a vintage feel.

Particularly, it is desirable that the outermost surface of the rolled fabric, which is rotated by the inside of the antique and processed by friction, is prevented from being excessively worn by friction so that the outermost side of the fabric can be used after the friction process is finished , It is important to take up the back side of the fabric so that it comes out to the outside.

The fabric is cut into a certain length and fastened inside, and the fabric is wound at once and rotated. At this time, when the primer rotates, it is cut to a certain length, and then it rises up to the upper part along the rotation of the fabric, and falls down and collides with the surface while the surface is worn down to partially peel off the coating. The part is formed and gives a unique atmosphere that is old.

It is preferable to rotate for 2 to 6 hours because the thickness of the coated coating layer 11 on the surface of the fabric 1 is different from the thickness to be worn according to the thickness of the fabric and the application amount of the chemical.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
