Description

EQUIPMENT FOR FIBRILLATION PROCESS

OF FABRIC

Technical Field

The present invention relates to an equipment for fibrillation process of fabric, and more particularly, to an equipment for fibrillation process of fabric in which the fabric is disposed in an in-line manner to be continuously spread and is then subject to a brush friction process, whereby it can accomplish the automation of all processes, the increment of production, the decrement of water for use and waste water, and the process applicable for various kinds of fabrics.

Background Art

Generally, a fibrillation process for fabric is intended to frictionize or raise mechanically the fabric which has been wet to partly disconnect or separate the connections of filaments formed on the surface of the fabric, thereby achieving the effect of raising the fine fibrils on the surface of the fabric. The fibrillation process is widely used as a process method for the high quality of fabric, together with an ultra softening process for softening the fiber cores forming the fibers on the interior of the fabric or for chemically reducing an amount of the fiber cores. The fabric for which the fibrillation process or the ultra softening process has been completed generates powder touch, peach skin touch, rose touch and the like. Specifically, the fabric product with the fibrillation process is characterized in that since it forms fine fibrils on the surface thereof, it has somewhat faded colors to look greatly elegant and refined. In addition, if it is transformed into desired clothes and is worn, it can prevent pilling commonly occurring on other fabrics which partly raises cut fabric on the surfaces of the fibers caused due to the friction between the fabrics, thus to twist or gather the fibers. A conventional equipment for the fibrillation process of the fabric has been used with a rotary washer which is a kind of a washer for use in an industrial field.

In other words, the fabric is cut every about 46 m in a length direction and the cut fabric is twisted to take a rope shape. Then, the roped fabric is inserted into the rotary washer and is rotated and frictionized for a long period of time in the water, thereby completing the fibrillation process of the fabric.

During the roped fabric is rotated in the water, however, it is frictionized in a twisted or gathered manner. Unfortunately, the conventional method creates the problems as follows: wrinkles of the product after the completion of process; uneven process result; difficulty of production of a high quality of product; and damage of the high-priced fabric due to the increment of poor quality of products .

In addition, to prevent the fabric from being twisted, the rotary washer stops its operation by the intervals of about 30 to 60 minutes. Next, the wet fabric is drawn from the rotary washer and the twisted fabric is untwisted. Then, the untwisted fabric is inserted into the rotary washer. The above process is repeated until the total process time of about 4 to 8 hours elapses. Moreover, the quantity of the fabric to be inserted into the rotary washer at one time is restricted, which reduces the efficiency of productivity and the amount of the production.

Furthermore, the automation of the equipment is not realized, and because the process depends upon the skill of an operator, the standardization of the technology is not possible. The amount of water for use and waste water is increased to cause the pollution of environments, thus to raise the energy cost load.

Therefore, the fabric 1 wound on the fabric roll 6 is inserted between the pair of pressure roller 204 and is processed along a predetermined path, while maintaining the continuous state of the fabric 1 by the spreading roller 205.

The above construction of the fabric supplying unit 2 is general supplying the fabric 1 to a specific process equipment, but it may be modified and varied by those skilled persons this field without departing from the spirit or scope of the instant invention.

The roller friction processing unit 60, as shown FIG. 7, includes: a coating friction roller 67 contacted with the surface of the fabric 1 conveyed by means of a pair of conveying rollers 61 having both ends connected to a conveying belt 62 and rotated by a conveying pulley 63 to thereby frictionize the fabric 1; a roller rotator for rotating the coating friction roller 67 centering around the rotating axis horizontal to the forwarding direction of the fabric 1 by means of a motor 68; a roller vibrator for vibrating the coating friction roller 67; fabric contacter for increasing the contact surface of the coating friction roller 67 with the fabric 1; and a water sprayer 69 installed on the front and rear portions of the coating friction roller 67 to supply the water to the fabric 1 passing through the coating friction roller 67.

The roller vibrator includes: a carriage 79 rotatively supported and connected on a rotary axis of the coating friction roller 67 to thereby move straight the coating friction roller 67 on the rotary axis thereof; a crank arm 77a hmge-coupled with the carriage 79 and with a fixed plate where a reciprocating groove 78 is formed to guide the reciprocation of the carriage 79, the crank arm having the one side connected to the carriage 79 for performing straight reciprocation and having the other side for performing a rotary movement; a crank 77 hmge-coupled and being eccentric to the one side of the crank arm 77a being rotary; a crank axis 77b serving as the rotary axis of the crank 77; a motor 73 for generating a rotary force; and a belt 75 and driving and driven pulleys 74 and 76 for connecting the motor 73 and the crank axis 77b to transmit the rotary force of the motor 73 to the crank axis 77b.

Meanwhile, it is preferable that the pneumatic controller 71 is provided with a pneumatic lever 72 to produce the air pressure m the pneumatic cylinder 66.

As shown m FIG. 8, to fabricate the coating friction roller 67, a predetermined size of aluminum oxide polishing particles are coated together with a resm to a nonwoven fabric which is made of a nylon fiber, and then the coated fiber is dispersed on the outer surface of the roller 72 m the length direction with an appropriate density m accordance with the type of the fabric 1. Finally, the coating friction roller 67 is secured on the circumference of a metal core by means of a resm.

The coating friction roller 67 is replaced with a double-edge type tooth friction roller which is made of a steel material and forms a slanting line of tooth symmetrically on the center of the cylindrical roller, a gear edge of the tooth comprised of a sharp edge having a small sectional angle and a dull inclined edge having a large sectional angle, a groove friction roller which is made of a metal material and forms spiral concave/convex grooves symmetrically on the center of the cylindrical roller, or a groove friction roller which is made of a metal material and forms equalizing concave/convex grooves by predetermined intervals to be horizontal in the length direction of the cylindrical roller. In accordance with the characteristic of the process, these rollers are partly or all selected to be arranged in serial in the advancing direction of the fabric 1, and otherwise, any other type of friction roller may be embodied.

Four brush frictionizing units 4, as shown in FIG. 1, in accordance with the preferred embodiment of the present invention are arranged continuously on the first layer to process the front surface of the fabric 1. After the completion of the process for the front surface of the fabric 1, the back surface thereof is disposed upwardly and four brush frictionizing units 4 are arranged continuously on the second layer to process the back surface thereof. FIGS. 2 and 3 show one of the plurality of brush friction units 4. As shown, the brush frictionizing unit 4 is comprised of : the brush 9 being in contact with the surface of the fabric 1; a brush right and left vibrator 12 for vibrating the brush 9 in the right and left directions of the fabric 1 along a right and left guide bar 11 by the eccentric rotation of a motor 10; a brush before and behind vibrator 15 for vibrating the brush 9 in the before and behind directions of the fabric 1 along a before and behind guide bar 14 by the eccentric rotation of a motor 13; a brush ascender/descender 17 for selectively ascending/descending the brush before and behind vibrator 15 by means of a hydraulic cylinder 16 to selectively contact the fabric 1 with the brush 9; and a brush ascending/descending position adjustor 18 for screw- adjusting the ascending/descending position of the brush ascender/descender 17 to control the contacted degree of the fabric 1 with the brush 9.

In other words, the brush ascender/descender 17 is constructed to include the hydraulic cylinder 16 for ascending/descending an ascending/descending frame 19 where the brush right and left vibrator 12 and the brush before and behind vibrator 15 are installed. The ascending/descending frame 19 forms four vertical guide bars 20 in parallel to each other to guide the ascending/descending movement of the ascending/descending frame 19. At this time, the brush ascending/descending position adjustor 18 is adapted to adjust the descending height of the ascending/descending frame 19, and it passes through the vertical guide bars 20 to support the ascending/descending frame 19 descended by means of the hydraulic cylinder 16. The adjustor 18 is comprised of four supporting legs 21 whose height is adjusted by the forward/backward operations of the screw.

In more detail, the supporting legs 21 are rotated to adjust the height thereof and upon the descent of the ascending/descending frame 19, they can adjust the contacted degree of the brush 9 with the fabric 1.

The brush ascending/descending position adjustor 18 may be replaced with any adjustor in an automatic adjusting manner using a motor or a hydraulic cylinder.

Also, the brush before and behind vibrator 15 is constructed to include a before and behind vibration frame 22 which is vibrated the before and behind directions of the fabric 1 along the before and behind guide bar 14 which is formed on the ascending/descending frame 19.

In this case, the before and behind vibration frame 22 converts the rotary movement of an eccentric rotary axis 23 rotated by means of a motor 13 fixed on the ascending/descending frame 19 into a straight reciprocating movement via a rectangular hole 24 into which the one end of the eccentric rotary axis 23 is inserted and is thus vibrated m the before and behind directions of the fabric 1.

The brush right and left vibrator 12 is installed on the before and behind vibration frame 22 and includes a right and left vibration frame 25 which is vibrated m the right and left directions of the fabric 1 along the right and left guide bar 11 which is formed on the before and behind vibration frame 22.

In this case, the right and left vibration frame 25 has the brush 9 fixed on the one side thereof, and converts the rotary movement of an eccentric rotary axis 26 rotated by means of the motor 10 fixed on the before and behind vibration frame 22 nto a straight reciprocating movement via a rectangular hole 27 into which the one end of the eccentric rotary axis 26 is inserted and is thus vibrated m the right and left directions of the fabric 1. Therefore, during the advancement of the fabric 1, the brush 9 is vibrated m the before and behind directions and at the same time m the right and left directions by means of the brush before and behind vibrator 15 and the brush right and left vibrator 12 to uniformly frictionize the surface of the fabric 1. If required, the brush 9 is ascended by means of the brush ascender/descender 17 to make the management of the equipment considerably easy, and upon the descent of the brush 9 by means of the brush ascending/descending position adjustor 18, the contacted degree of the brush 9 and the fabric 1 can be adjusted.

In the meanwhile, to fabricate the brush 9, a predetermined size of aluminum oxide polishing particles are coated together with a resin to a nonwoven fabric which is made of a nylon fiber, and then the coated fibers are overlapped and bound by means of an adhesive such as a bubbling binder or a resin to be thereby secured on the supporting plate of an aluminum or metal material .

The brush right and left vibrator 12 is comprised of : a first brush right and left vibrator 29 which vibrates a first brush 28 in the right and left directions of the fabric 1 along the right and left guide bar 11 by the eccentric rotation of the motor 10; and a second brush right and left vibrator 31 which vibrates a second brush 30 in the direction opposite to the first brush 28 along the right and left guide bar 11 by the eccentric rotation of the motor 10. This is intended to offset the right and left vibration of the first and second brushes 28 and 30 to thereby minimize the fatigue degree applied to the equipment of the present invention as well as the amount of vibration. The first and second brushes 28 and 30 are respectively arranged in two rows, and a water sprayer 32 where a plurality of nozzles are formed to disperse a high pressure of water to the fabric 1 is installed between the two rows of the first and second brushes 28 and 30. Also, a bucket 33 is installed on the downward direction of the brush 9. The water sprayer 32 is installed to take a bar shape across the width of the fabric 1 to uniformly supply the water over the whole width of the fabric 1.

As shown in FIGS. 4 and 5, on the other hand, the conveyor belt unit 3 for conveying the fabric 1 supplied from the fabric supplying unit 2 is comprised of: a driving roller 37 driven by the activation of a motor 36 assembled with a belt 34 and a pulley 35; a driven roller 38 driven by means of the driving roller 37; a conveyor belt 39 wound and rotatively driven on the driving roller 37 and the driven roller 38 to convey the fabric 1 arranged on the one side thereof.

In this case, the conveyor belt 39 is made of various kinds of materials, preferably a flexible rubber.

The conveyor belt unit 3 includes: a sensor 40 for sensing the right and left deviation of the conveyor belt

39; a controller 41 for receiving a deviation signal from the sensor 40 to apply the received deviation signal; and a belt position adjusting roller 43 positioned between the driving roller 37 and the driven roller 38 and formed slantly in the right or left direction on the basis of the forwarding direction of the conveyor belt 39, thus to be selectively inner-contacted with the inside of the conveyor belt 39, while being ascended/descended by means of a hydraulic cylinder 42 to which the control signal of the controller 41 is applied, thus to prevent the right and left deviation of the conveyor belt 39.

The conveyor belt unit 3 further comprises: a supporting plate 44 for supporting the one side of the conveyor belt 39 to prevent the one side of the conveyor belt 39 from being loose; and two pairs of pressure rollers 46 disposed m the front and back directions of the brush frictionizmg units 4, respectively and for pressing the conveyor belt 39 and the fabric 1 by means of a hydraulic cylinder 45 to thereby prevent the conveying position of the fabric 1 on the conveyor belt 39 from being deviated by the brush frictionizmg unit 4. The conveyor belt unit 3 is installed to dispose the fabric 1 on the top surface of the conveyor belt 39 rotating the fabric 1 m the spread state supplied from the fabric supplying unit 2 and to move the fabric 1 together with the conveyor belt 39 passing through the pressure rollers 46. This is intended to prevent the deviation m every direction of the fabric 1 caused due to the activation of the brush frictioniz g units 4, while moving the fabric 1 along the advancing direction of the conveyor belt 39. On the other hand, the fabric cleaning unit 5, as shown m FIG. 1, is installed to remove the residuals such as fine fibrils generated during the fibrillation process and remaining on the surface of the fabric 1.

In this case, the number of the angular roller 50 as shown in FIG. 6 is preferably two, each of which is contacted with the front and rear surfaces of the fabric 1 to remove the residuals on all of the front and rear surfaces thereof. The angular roller 50 has the three- angled, four-angled, or five-angled section, preferably eight-angled section. In more detail, in the eight-angled roller 50, the edges where the eight angles exist respectively are rotated to collide against the fabric 1, and the eight -angled roller 50 is made of a wood roller to prevent the damage of the fabric 1. Accordingly, the fabric 1 which has been passed through the brush frictionizing unit 4 is poured into the washing water 47, and the residuals remaining on the firstly washed fabric 1 are removed by means of the rotating angular roller 50. In this case, the washing water 47 is filled with an uncontaminated water every time or is circulated to be thus purified by means of a filter. Preferably, the washing water 47 is used with water.

As shown in FIG. 9, on the other hand, the fabric tapping unit 80 is comprised of: a base plate 92 where the fabric 1 is disposed; a plurality of tapping bars 90 installed perpendicular to the forwarding direction of the fabric 1 and rotatively vibrated, for tapping the upper surface of the fabric 1 disposed on the base plate 92; a coupling plate 89 for coupling the both ends of the plurality of tapping bars 90; a vibration transmitting plate 88 for transmitting the rotary vibration to the coupling plate 89; a rotary axis 85 installed and rotated perpendicular to the forwarding direction of the fabric 1; and a plurality of springs 90 installed between the end and ceilings of the coupling plate 89 to minimize the influence of gravity applied to the tapping bars 90 and to an eccentric rotator 86 fixed on the vibration transmitting plate 88 which converts the rotation of the rotary axis 85 into the rotary vibration to transmit the converted vibration to the vibration transmitting plate 88, thus to provide their restoring forces to the plurality of tapping bars 90.

The rotary axis 86 is installed perpendicular to the forwarding direction of the fabric 1 and has the both ends and the center thereof rotatively supported by a lower supporting member 97 fixed on the base plate 92 and an upper supporting member 87 fixed on the ceiling surface of the rotary axis 86. The rotary axis 86 is rotated by the reception of the rotary force generated by a motor 81 from a belt 83 and driving and driven pulleys 82 and 84. As shown FIG. 10, the eccentric rotator 86 which is adapted to be connected on the vibration transmitting plate 88 which converts the rotation of the rotary axis 85 into the rotary vibration to transmit the converted vibration to the vibration transmitting plate 88, is comprised of: a disc type of eccentric rotating plate 95 installed and rotated eccentrically to the rotary center of the rotary axis 85; a fixed member 96 for coupling and fixing the rotary axis 85 and the eccentric rotating plate 95; and a vibration plate 94 on which the eccentric rotating plate 95 is installed and connected via a bearing with the eccentric rotating plate 95 for performing a sliding movement, the vibration plate 94 having the lower end thereof fixed on the vibration transmitting plate 88 for performing a rotary vibration movement.

Now, an explanation of the operation of the equipment for fibrillation process of the fabric in accordance with a preferred embodiment of the present invention will be discussed.

If the fabric roll 6 is unrolled to supply the fabric 1 towards the conveyor belt unit 3 by means of the activation of the fabric supplying unit 2, the conveyor belt unit 3 on the first layer conveys the fabric 1 horizontally without any deviation of position thereof. At this time, the brush 9 of the brush frictionizing unit 4 forms the friction on the surface of the fabric 1 to start the fibrillation process of the fabric 1. In this case, prior to the unrolling of the fabric 1 from the fabric roll 6, the foreign materials on the fabric 1 are removed within the water tub 203 and the fabric 1 absorbs the water. Next, the both surfaces of the fabric 1 are frictionized by means of the roller friction processing unit 60.

After the process of the front surface of the fabric 1 is completed, the fabric 1 is horizontally conveyed by the conveyor belt unit 3 on the second layer, so that the back surface of the fabric 1 is processed by the operation of the brush 9 of the brush frictionizing unit 4, in the same manner as the front surface thereof.

Next, the fabric 1 which is guided to the fabric cleaning unit 5 via a conveying roller 7, is poured into the washing water 47 of the washtub 48 via the pressure rollers 54, and the residuals remaining on the washed fabric 1 are removed by means of the rotating angular roller 50. The fabric 1 from which the washing water 47 is removed by the pressure of the pressure rollers 54 is dried to perform the fibrillation process for the fabric 1. Thereafter, the fabric 1, which is continuously conveyed, receives impact caused by the activation of the fabric tapping unit 80, thus to soften the fiber cores of the interior of the fabric 1. Moreover, the fabric processed by the equipment for fibrillation process of the fabric of the present invention experiences the ultra softening process or any various processes and is then dewatered by means of a vacuum dewaterer. Then, the fabric is fully dried to produce a complete product.

The fabric moves continuously in the spread state and is processed for the fibrillation, and an amount of production for one day is approximately 14,400 m, assuming that the mean velocity per minute of 10 m and a work efficiency of 80% for one day per one equipment, which indicates the increment of about 20 times when compared with an amount of production for one day of about 736 m for the four roped textures of about 46 m on the basis of six hours at one time. The automation of all processes in the equipment of the present invention is achieved to implement an unmanned operation, and moreover, no color difference and appearance difference on the complete product is exhibited. Additionally, no wrinkles on the product is formed, and an amount of the water for use is greatly reduced to prevent the pollution of environment.

Furthermore, fabric roll product having various length can be produced, if required, and each component of the equipment of the present invention can be displaced and reconstructed in accordance with the characteristics of the product . Industrial Applicability

As set forth in the above, an equipment for fibrillation process of fabric in accordance with a preferred embodiment of the present invention has the following advantages: 1) it can prevent the fabric from being wrinkled and achieve the uniform the process result, to thereby manufacture a high quality of product; 2) it can manufacture products in large quantities and accomplish the reduction of the product cost, the optimized production efficiency, and the standardization of the operating technology; and 3) it can reduce the amount of water for use and waste, prevent the pollution of environments, and lower the energy cost load. It will be apparent to those skilled in the art that various modifications and variations can be made in an equipment for fibrillation process of fabric of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
