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

The fabric used in the present invention includes a fabric, such as a fabric, whose surface is not smoothly formed, but which has a specific texture when the surface of the fabric is in contact with the surface of the fabric.

The fabric is used for clothes, carpets, car seats and the like, and can be provided with general fabrics, knitted fabrics or nonwoven fabrics. Specifically, flat fabrics woven with jacquard or dobby, flat cloth knitted with a tricot knitting machine It is knitted using Double Raschel or Tricot knitting machine which is knitted by using Flat Tricot and Double Raschel knitting machine and slit the center to form a pile, The buffing process is added to create a tricot suede with short pile with artificial leather texture similar to that on the surface.

(Tricot Suede), knitted using a tricot knitting machine, tricot cut, which is made by cutting the surface through a SH (Shearing) process after the file is set up through a brushed process, and knitted using a cylindrical knitting machine Circular Knit, Knitted Mesh (MESH) or DNB Mesh (Space Fabric) with Double Raschel Knitting Machine, Sinker Pile with File through Sinker Parts with Upper Flat Machine Can be used.

The material of the fabric may be a fabric made of natural fibers, man-made fibers, synthetic fibers, or a fabric made of fibers blended with the fibers.

In this conventional technique, a coating layer capable of performing waterproof, water-repellent and antifouling functions is formed by using a coating method such as laminating on the fabric. When such a coating layer is formed, due to the thickness of the coating layer itself, And it was difficult to process or decorate the surface of the coating layer.

In the present invention, it is possible to form a fine coating layer on the surface of the fabric, which can easily remove water droplets, pollutants and other chemicals provided from the outside while maintaining the texture specific to the fabric as much as possible, , Waterproof, water repellent, antifouling performance, and chemical resistance to chemicals such as bleaching agents.

In addition, the present invention provides a fabric capable of maximizing the dressing property or the aesthetic feeling, which gives a feeling of chirping by forming a repetitive bending state when the weight of the fabric is increased and the product is hanged in a vertical direction.

For this purpose, in the present invention, the additives for preparing the absorbent and the coating agent are selected and the mixing conditions between them are designed.

A suitable additive such as a water repellent agent and an antifouling agent capable of maximizing water repellency and antifouling property is selected through this, and in particular, a mixing condition capable of achieving a matte effect without using a quencher is designed.

The optimum process for effectively absorbing and coating the selected absorbent and coating agent on the fabric is also mentioned.

For this purpose, we design the optimum processing method, design the kind of coating knife according to the type and thickness of the fabric, angle and pressure, and design the pressure and temperature condition of the roller used for coating .

In order to develop optimal water repellency and stain removal processing conditions, the conditions and application amount for the dipping coating are designed, and the appropriate temperature and other absorption conditions at that time are set.

If the application of the coating material is too thick, the touch feeling of the fabric becomes thick or stiff. This is because the uniform coating application technique is required to be advanced and the soft coating material Can be provided.

Further, conditions for performing a proper post-treatment, that is, a tentering process, with respect to the fabric material after the coating operation are required.

In the present invention, a fluorine-based absorbent is used for effective water repellency and oil repellency. The characteristic of the fluorine-based absorbent is that the inside of the fiber and the surface thereof are coated with a very small amount of fluorine polymer, so that the inherent feel and permeability of the fiber base material is not impaired.

As shown in FIG. 1, when the fluorine-containing monomer and the silicon macromonomer are copolymerized in the prior art, such a copolymer polymer has a problem that the silicon component is preferentially separated from the surface after film formation.

Therefore, there is a limit in showing the oil-repelling performance.

However, the absorbent used in the present invention can combine fluorine and silicon at the molecular level to combine the characteristic of excellent water and oil repellency of fluorine and the property of not inhibiting the touch of silicon. Due to the technology, excellent water and oil repellency and feeling of fiber of silicon can be compatible with both characteristics.

In the case of sorbents in which fluorine and silicon are compounded at the molecular level, when the heat is applied, the silicone component seeps under the surface or the surface of the fabric so as to maintain the texture of the fabric, and the fluorine component is located on the surface of the fabric, Indicates the oil-repellent performance.

The fluorine-based component used in the present invention is a fluorine polymer having both a water-repellent component derived from a perfluoroalkyl group and a hydrophilic component derived from a polyoxyethylene group in one molecule.

As shown in FIG. 2, a perfluoroalkyl group, which is a minority and proprietary group in the air, is discharged to the outside, and a polyoxyethylene group, which is a hydrophilic group, is oriented toward the inside, A polyoxyethylene group, which is a perfluoroalkyl group oriented inward and a hydrophilic group, has an externally oriented flip-flop phenomenon, and water is wetted at the interface between the fibers and fibers. Thereby making it easier for the contaminants to float and fall off.

Flip-flop phenomenon makes it easy to remove oil stains attached to the fibers, so that the attached contaminants tend to fall off.

The dipping process for absorbing the absorbent to the fabric fabric used in the present invention occurs over a total of four times.

The dipping process is a process in which the fabric is temporarily absorbed into the absorbent so that the absorbent is absorbed into the inside of the fabric and the surface. After the dipping process, a dewatering process must be performed to pass the fabric through the rollers that are in contact with each other.

This dipping process is performed by a dipping apparatus composed of a container and a dipping roller, and the dewatering process is performed by a mangle machine having two mating rollers.

If necessary, a coating operation using a knife may be interposed between the first dipping step and the second dipping step. Or between the third and fourth dipping steps, not between the first and second dipping steps.

Further, a coating process using a knife may be interposed between the first and second dipping steps and between the third and fourth dipping steps.

3 to 6 show flowcharts of different embodiments according to the presence or absence of the first to fourth dipping processes and the knife coating process disposed therebetween and intervening positions.

3, the first dipping and dewatering step (S10), the first drying step (S12), the second dipping and dewatering step (S20), and the second dipping and dewatering step Followed by a first tentering step (S22). This is referred to as a first stroke S1.

The drying step (S12) is a step of dipping and dewatering and drying the absorbed fabric with hot air.

The tentering step (S22) is a step of reducing the width of the fabric in advance so that the fabric using the fabric itself or the fabric is reduced so that the fabric is not stained and water repellent performance is not damaged.

When the first stroke S1 is completed, the second stroke S2 is carried out. The second stroke S2 is followed by the third dipping and dewatering step S30, the second drying step S32, A fourth dipping and dewatering step (S40), and a second tentering step (S42).

The hardware for implementing one stroke includes the feeding roller 100 shown in FIG. 7, a first dipping apparatus 110, a first mung machine 120, a drying apparatus 140, a second dipping apparatus The first mung bean machine 120 and the drying apparatus 140 are formed by a first mung machine 210, a second mung machine 220, a tentering apparatus 300 and a take-up roller 400, A knife coating apparatus 130 may be optionally included.

When one stroke is completed, the winding roller wound with the fabric passing through the previous stroke is moved to the feeding roller seat for the next stroke, and the next stroke is performed.

On the other hand, in the first drying step, 60% to 70% of the dried material is dried, not the 100%, but 60% to 70% of the dried material.

The reason for drying in a slightly semi-dry state in this manner is that when a post-dipping step (for example, a second dipping step) is performed in a state in which the absorbent absorbed by the pre-dipping step (for example, the first dipping step) , And the absorbent that has already been absorbed by the pre-dipping step is introduced into the fabric through the pre-dipping step, which is provided in the post-dipping step, thereby increasing the water absorption rate to the fabric.

In general, when the absorption state of the absorbent in the first dipping step is 75 to 80%, the absorption state of the absorbent in the second dipping step is about 88 to 90%, in the third dipping step, 93 to 94% Depending on the process, it is 98 to 100%.

That is, a single dipping step is not completely absorbed into one fabric, so that the dipping process is performed a plurality of times as described above. However, due to the attraction between the absorbent molecular component in the fabric and the absorbent molecular component outside the fabric, Absorbent molecules can penetrate the outside of the fabric.

FIG. 4 shows a knife coating process S11 added in the first stroke S1 shown in FIG. 3, and FIG. 5 shows a knife coating process S31 added in the second stroke S2 shown in FIG. .

6 shows that the knife coating processes S11 and S31 are added to the first and second strokes S1 and S2 shown in FIG. 3, respectively.

The knife coating step S11 added to the first step S1 is performed between the first dipping and dewatering step S10 and the first drying step S12, The coating step S31 is preferably performed between the second dipping and dewatering step (S30) and the second drying step (S32).

As shown in FIG. 7, the unit for performing the unitary operation includes a feeding roller 100, a first dipping apparatus 110, a first mung machine 120, The second mopping machine 220, the tentering machine 300 and the winding roller 400, and the first mopping machine 120, the second mopping machine 220, A knife coating apparatus 130 may be optionally provided between the drying apparatus 140 and the drying apparatus 140.

The reason for placing the dotted box around the knife coating apparatus 130 is to indicate that the knife coating apparatus 130 can be disposed or omitted depending on the situation.

The first and second dipping apparatuses 110 and 210 include support rollers 112 and 212 which are accommodated in the receiving containers 111 and 211 and the receiving containers 111 and 211 so as to allow the raw material passing through the dipping process to be supported while maintaining tension. .

The first and second mung machines 120 and 220 are formed by two rollers which are slightly spaced from each other and appear to be apparently in contact with each other.

Therefore, when a dipped cloth passes between the two rollers, the absorbent absorbed by the fabric is dewatered, and only a part of the absorbent remains on the surface and inside of the fabric.

A knife 131 is provided on the knife coating apparatus 130 and a support base 132 is provided under the knife 131 to form a coating layer having a fine gap between the surface of the raw material S and the tip of the knife 131 (c), c) is formed.

In this case, the operator supplies the coating material (a) to the surface of the material to be coated in front of the knife 131.

Figure 8 illustrates the process of adding absorbent and optionally a coating to the fabric when one run is performed.

As shown in Fig. 8 (a), only the base material S of the fabric is present before the absorbent or the coating agent is added.

In this state, the absorbent layer A is formed inside and on the surface of the substrate S when passing through the first dipping apparatus 110 and the first mung machine 120.

When the knife coating apparatus 130 is selectively placed in this state, a coating layer C is formed on the surface of the substrate S as shown in FIG. 8 (c).

After passing through the second dipping apparatus 210 and the second mung-up machine 220 after the drying process, the absorbent penetrates into the substrate portion S through the coating layer and is absorbed.

At this time, as described above, the external absorbent can easily penetrate into the substrate portion S by the attraction force between the absorbent already inside the substrate portion S and the absorbent outside the substrate portion.

Hereinafter, components of the absorbent used in the first to fourth dipping steps and components of the coating agent used in the knife coating process will be described.

The components of the absorbent used in the first dipping step are as follows.

In the coating process, the distance between the end of the knife and the surface of the fabric is preferably 1 to 3 mm, and the coating amount is preferably 30 to 50 g per 1 m ² .

The pressure applied to the fabric by the surface of the roller during the dipping step is preferably 3.0 to 3.5 kgf / cm ² , and the surface temperature of the roller is preferably 100 to 120 ° C.

On the other hand, in the case of the tentering process, the coating process of each order is completed before the coating process of the next order is completed. In this case, the tentering process conditions by the tentering device are as follows.

fair Temperature (℃) Speed (yd / min)) Width after shrinkage (inch) Primary Tentering 160-170 3 to 4 56 " Second tenting 160-170 3 to 4 56 "

When performing a number of dipping processes and selective coating processes as described above using such absorbents and coatings, the weight of the fabric increases after complete drying. Fabric (Fabric) Fabric weight is increased by 30 ~ 60g, which is about 280 ~ 320g based on 56 inch.

Thus, when a beam made of such a fabric is placed on a table or other furniture, the lowered portion is formed to be curved like a curtain or a dress, thereby maximizing aesthetic sense.

Further, the water repellent function can be improved by the water repellent function and the oil repellent function by this process, and the flexibility of the fabric can also be increased.
