Description

Apparatus for steaming fabric and method of same

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a fabric coagulating apparatus and a steam heating method, and more particularly, to a technique capable of increasing thermal efficiency by improving a supply method of steam for heating a fabric.

In general, dyeing refers to dyeing the dye to be dyed using dyes, pigments or other chemicals.

This dyeing uses dyeability of the dye to sorb or fix the dye to the fiber and is largely classified into a dip dyeing and a printing dyeing.

The dipping is a method in which the fabric is immersed (dipped) in a dye liquid, taken out after a predetermined time at an appropriate temperature, and then washed with water and dried to complete dyeing.

In addition, the printing is a dyeing method in which the fabric is partly colored and the pattern is colored so that the fabric is dyed by stamping the printing paste containing the dye.

This printing process is done through the pre-processing consisting of design making, drafting, plate making, blending and testing work, and post-processing work consisting of work, inspection, and packaging consisting of days, steam, water, and drying.

Particularly, this work includes the day, heat, water, and drying process. The printing process is a process of pouring dyes into a screen frame installed as many as the number of colors on a printing base and then using a squeegee to print patterns by color.

The steaming process is a steam-boiling process to fix the dye on the fabric, increasing the dyeability and fastness (fastness).

In general, the knotting and steam-heating processes are continuously performed, and the knitted fabric is transferred to the steam-heating device and the steam-heating process is performed.

At this time, the fabric is entirely heated by using a tubular heat-collecting device, or the fabric is heated by using a continuous heat-collecting device.

In the case of the continuous steam plant, the moving raw material enters the chamber and then moves up and down while forming a loop. In this process, the dye is stably mixed with the raw material by being heated by the saturated or heated steam such as steam .

And, the steam is generated by the steam generator, and the steam generator generates steam by the light oil or the gas.

Here, the reason why the temperature of the steam is increased by heating the steam is that polyester can be colored only when the temperature of the polyester is 170 ° C or higher.

However, in the case of such a continuous steam plant, since diesel oil or gas is used as a heat source to generate steam, there is a problem that energy cost is increased due to high oil price.

Therefore, a far infrared ray system may be applied as an auxiliary heat source. That is, an IR lamp is installed inside the chamber to radiate far-infrared rays while spraying steam, thereby performing heat treatment.

However, since the far infrared ray method is insufficient in moisture, fabrics such as polyester can be dyed without humidity, but in the case of fabrics such as cotton, there is a problem that the moisture is insufficient and the dyes can not be dyed.

In addition, there is a problem in that the coloring of the dye is not activated by the far-infrared ray method and the color does not vividly survive.

Patent Application No. 10-2011-49945 (far infrared ray dyeing apparatus)

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a fabric finishing apparatus and method capable of enhancing energy efficiency by combining a steam injection system and a water injection system.

It is another object of the present invention to provide a fabric finishing apparatus capable of enhancing the heating efficiency by improving the structure in which steam and water are mixed and injected.

As described above, the fabric finishing apparatus and method according to one embodiment of the present invention have the following advantages.

First, the high-temperature steam is firstly injected by the main steam supply unit, the water injected by the water supply unit is brought into contact with the electric heater to generate secondary steam, and the primary and secondary steam are mixed with each other, The humidity and the temperature in the chamber can be maintained without generating additional energy costs, and the charge ratio can be reduced by about 80%.

Second, since a blower is disposed at a position adjacent to the main steam supply unit, a low pressure is formed between the injection holes of the steam pipe due to the velocity of the air blown from the blower, so that the steam injected from the steam pipe due to such pressure difference is steamed To the inside of the chamber.

Third, by disposing a separation plate between the main steam supply unit and the water supply unit, it is possible to prevent the temperature of the water sprayed from the main steam supply unit from falling due to contact with the steam sprayed before the water reaches the heating unit.

Fourth, the electric heater is disposed on the path of water spraying of the water supply portion, but the steam sprayed from the main steam supply portion is mixed with the water that contacts the electric heater by preventing the steam from interfering with the spraying route of the main steam supply portion The temperature can be prevented from being lowered and the energy efficiency can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0029] Hereinafter, a fabric finishing apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 3, the fabric coagulant 1 proposed by the present invention combines the steam injection method and the water injection method to efficiently perform the steam heating process on the fabric f.

In the fabric finishing apparatus 1, at least one or more of the chambers 3 are disposed on one side or both sides of the chamber 3.

The fabric coagulating apparatus (1) comprises a chamber (3) to which a raw material (f) is fed and to be heated; A main steam supply unit 5 for primarily supplying steam to the inside of the chamber 3 to heat the fabric f; A water supply unit 7 disposed adjacent to the main steam supply unit 5 to inject water into the chamber 3; The main steam supply unit 5 and the water supply unit 7 to further heat the steam supplied from the main steam supply unit 5 and to steam the water jetted from the water supply unit 7, A heating unit 9 for generating steam mainly; And a guide plate 11 for circulating steam generated primarily and secondarily along a locus of the chamber 3.

In the fabric finishing apparatus having such a structure, the chamber 3 is formed with a space therein so that the fabric f can be transported in the form of a loop 20. That is, a plurality of fabric fingers R are disposed on the upper portion of the chamber 3 and the fabric f is sequentially hooked on the hook R to form the loop 20 in the vertical direction.

This hook is disposed inside the chamber 3 and connected to the chain C rotating along the elliptical trajectory in the forward and backward directions. Therefore, when the chain C rotates along the locus, the hanger R also rotates, so that the fabric f caught by the hanger R can also be transported in the outward direction from the entrance of the chamber 3. [

The main steam supply unit 5 supplies steam to the inside of the chamber 3 to create an environment of high temperature and high humidity. That is, the steam is mixed with the dye applied to the fabric (f), whereby the dyeing of the dye mixed with moisture is activated, so that the dyeing state is very stable and satisfactory, and the color sharpness of the dye is increased.

The main steam supply unit 5 includes a heater 13 for heating the water supplied from the water tank to a predetermined temperature; A duct (Duct) 16 for transferring the steam generated in the heater 13 to the interior of the chamber 3; A steam tube (15) for injecting steam transferred to the duct (16); And a blower 14 disposed at a position adjacent to the steam pipe 15 so as to form an air flow so that steam is injected into the chamber 3.

The heater 13 generates steam by heating water to a predetermined temperature by a heat source such as oil or gas such as light oil.

The generated steam is injected through the duct 16 and the steam pipe 15 due to the pressure of water boiling in the heater 13.

However, since it is difficult to inject steam sufficiently into the chamber only by the pressure of the heater 13 itself, the steam can be injected by the pressure difference caused by the flow rate of the air blown from the blower 14.

More specifically, when the blower 14 is driven, the pressure around the blower 14 is lowered due to the rapid flow of air discharged from the blower 14 in accordance with the Bernoulli principle, and the outlet of the steam pipe 15 Becomes a low pressure state.

Therefore, the steam generated in the heater 13 can be injected into the chamber 3 through the steam pipe 15 due to the difference in pressure.

As a result, it is preferable that the outlet of the steam pipe 15 is disposed within a range in which the pressure of the blower 14 acts. For example, when the output of the blower 14 is large, the outlet of the steam pipe 15 can be disposed at a position away from the blower 14. Conversely, when the output of the blower 14 is small, Is disposed at a position close to the blower 14. The blower 14,

On the other hand, in the case of cotton, silk or nylon, a good coloring efficiency can be attained when the temperature is in the range of 100 ° C to 110 ° C, but in the case of polyester, the coloring can be performed only when the temperature is higher than 180 ° C.

Therefore, it is preferable that the temperature of the steam generated from the heater 13 is more than 180 degrees in order to effect effective dyeing for both the cotton material and the polyester material.

However, in order to maintain the steam temperature above 180 degrees, the supply of oil or gas must be increased, leading to an increase in energy cost.

Also, when the inside of the chamber 3 is maintained at 180 degrees or more, the steam supplied into the chamber 3 becomes saturated due to the high temperature, so that the humidity is lowered and the coloring efficiency is lowered.

Therefore, in the present invention, the water supply unit 7 is applied as described above in order to keep the temperature inside the chamber 3 at 180 degrees or more and also to maintain the humidity.

That is, the water supply unit 7 injects water into the chamber 3, and the sprayed water comes into contact with the heater to be steamed, thereby raising the temperature in the chamber 3 and maintaining the humidity at the same time.

More specifically, the water supply unit 7 includes a water tank (not shown) in which water is stored; A water pipe (16) through which water stored in the water tank is transported by the pump; And a nozzle (18) mounted at an end of the water pipe (16) to spray water.

In this water supply part 7, the water pipe 16 is in the form of a branch pipe 19 whose ends are branched in both directions, and a nozzle 18 is mounted on the tip end of each branch pipe 19. Therefore, the water transferred through the water pipe 16 is divided into two directions by the branch pipe 19, and then is injected into the chamber 3 through the nozzle 18.

Of course, in the above description, the branch pipe 19 is branched in both directions. However, the branch pipe 19 is not limited to this, but can be changed appropriately according to the capacity of the steam heat exchanger 1.

A shutoff plate 17 is disposed between the water supply unit 7 and the steam pipe 15 of the main steam supply unit 7. Therefore, when water is sprayed from the nozzle 18 of the water supply part 7, it is sprayed in the form of fine particles. When the water of the particulate form comes into contact with the steam sprayed from the neighboring steam pipe 15, The shutoff plate 17 can be arranged to prevent the water particles from contacting the steam.

That is, the shield plate 17 guides the water jetted from the nozzle 18 and the steam jetted from the steam tube 15 to the heat generating unit 9 without being mixed with each other, so that the steam jetting system and the water jetting system It is possible to prevent the steam from being cooled by the water.

It is preferable that the blocking plate 17 has an appropriate length so that water and steam can be moved to the heat generating portion 9 without being mixed with each other.

The water sprayed through the nozzle 18 can be steamed by the high-temperature heat by contacting the surface of the heat-generating part 9 while being separated from the steam by the shutoff plate 17. [

The heat shielding plate 17 may be provided with a heat line to generate heat at a predetermined temperature to preheat the water sprayed from the nozzle 18. In this manner, the blocking plate 17 can efficiently steam the water by preheating the water.

The heat generating unit 9 has a shape in which a plurality of heat generating coils 21, which generate heat when electricity is supplied, are arranged in a loop 20.

That is, the heat generating portion 9 includes a plurality of loops 20 protruding from the inner wall surface of the chamber 3; A heat generating coil (21) disposed inside the loop (20) to generate heat; And a ceramic that is coated on the outside of the loop 20.

The plurality of loops 20 are disposed on the inner wall surface of the chamber 3 and protrude inward. Therefore, the water sprayed from the nozzle 18 can be evaporated and steamed by contacting the loop 20 made of the heat generating coil 21. [

At this time, the loop 20 of the heat generating portion 9 is disposed on the path of water spraying of the water supplying portion 7, and the steam injected from the main steam supplying portion 5 is in direct contact with the loop 20 It is desirable to pass a distance of a distance such that only heat transfer can be made.

That is, the steam injected from the main steam supply unit 9 is mixed with the water in contact with the loop 20 of the heat generating unit 9 to prevent the temperature from being lowered. At the same time, only the heat from the loop 20 is transferred, The efficiency can be increased.

As a result, the mixed steam in which the primary steam S1 injected from the steam pipe 15 and the secondary steam S2 generated at the surface of the loop 20 of the heat generating portion 9 are mixed is injected into the interior of the chamber 3 .

At this time, the heat of the heat generating coil 21 is transferred to the primary and secondary steam S1 and S2, so that the mixed steam contains more heat than the heat of the primary steam S1, 3). In addition, the second steam (S2) is generated while the water contacts the heater, so that the humidity is also increased.

Therefore, the steam heat exchanger 1 according to the present invention is effective to heat the noodles as well as the polyester because the humidity can be kept constant while the temperature is high.

The mixed steam having passed through the heater is supplied to the inside of the chamber 3 through the guide plate 11. The guide plate 11 has an inclined surface at an upper portion thereof and is inclined toward the outside.

Therefore, the mixed steam that has risen through the guide plate 11 spreads in four directions while passing through the inclined surface, and thereby spreads the fabric f more efficiently.

Hereinafter, a method of steam heating using the raw material steam heating apparatus of the present invention will be described in more detail.

As shown in FIGS. 1 to 4, the fabric finishing method proposed by the present invention includes a first step of spraying steam generated by the main steam supply unit 5 to the inside of the chamber 3, (S100); A second step (S110) in which the water sprayed by the water supply unit (7) contacts the surface of the heat generator; The steam injected in the first stage and the water injected in the second stage are brought into contact with the heat generating part to generate steam in a secondary direction, and at the same time, the steam generated after providing moisture is mixed into the chamber 3, And a third step (S120) of supplying heat through the heat exchanger (11).

In the first step S100, the heater 13 is heated by a heat source such as oil or gas such as light oil to a predetermined temperature to generate steam.

The generated steam is injected through the duct 16 and the steam pipe 15 due to the pressure of water boiling in the heater 13. At this time, since it is difficult to inject steam sufficiently into the chamber only by the pressure of the heater 13 itself, the steam can be injected by the pressure difference due to the flow rate of the air blown from the blower 14.

That is, when the blower 14 is driven, the pressure around the blower 14 is lowered due to the rapid flow of air discharged from the blower 14 in accordance with the Bernoulli principle, and the outlet of the steam pipe 15 is in a low- The steam can be injected into the chamber 3 through the steam pipe 15 due to the pressure difference.

In the second step S110, the water is injected into the chamber 3 through the nozzle 18 of the water supply part 7.

That is, the water stored in the water tank is supplied through the water pipe 16 and then injected through the nozzle 18.

At this time, a blocking plate 17 is disposed between the nozzle 18 and the steam pipe 15 to prevent water and steam from being mixed with each other.

In the third step S120, the sprayed water is supplied to the heat generating portion 9 to come into contact with the surface. At this time, the water jetted from the nozzle 18 can be evaporated and steamed by contacting the loop 20 made of the heat generating coil 21. [

The steam injected from the main steam supply unit 5 can further be heated by contacting the loop 20. At this time, it is preferable that the steam is passed through at a distance such that only heat can be transmitted, rather than direct contact.
