KR790001372B1 - Pre-finishing method of raised fabric - Google Patents

Abstract

A prefinishing method for completely presetting the direction of raised fabric was described. After fabric width was controlled in expander(5) by passing through guide bar(2), and tension bar(3,4), the raised fabric was treated to raise and rub by passing through a pair of delivery rollers(6,7) and guide rollers (8,10,12,14,15), raising rollers(9,11) and sandpaper rollers(13). A position of guide roller was varied to control contacting area of the raised fabric, raising roller and sandpaper roller. Finally, raised fabric was passed through a pair of take-up press rollers and finished by expander (18).

The present invention relates to a processing method for preliminarily fixing the raising direction of various kinds of brushed paper having irregular raising direction.

Conventionally, the production of brushed paper is processed by large-scale integrated process, such as dyeing, dyeing, brushing, sharing, coating, etc., and then processed brushed paper is produced. Processed paper is produced in the order of dyeing, brushing, and coating by separating the process.

However, in the case of producing processing brushed paper by separating each process without using the sharing brushing machine, not only the brushing length is uneven but also the uncut loop remains and the brushing direction is disturbed during the separate process, so the touch is poor. It was also possible to produce products with high added value due to the color difference.

In addition, coating may be performed after pretreatment so that the brushing direction is constant by a simple brushing method such as brushing under the same conditions after conventional brushing, but in this case, once or twice using brush apparatus of almost the same conditions As it was only repeated 3 times, problems such as bad brushing length and remaining of uncut loop could not be solved, and the simple brushing degree did not change the direction of raising under various conditions (temperature, pressure, etc.) during post-treatment. Since it could not be kept constant, the appearance defects caused by irregularities in the raising direction could not be eliminated.

The almost same conditions above refer to a brush device having the same size and size of the brush needle, or the same brushing angle, or to process brushed paper only with the brush.

Therefore, the present invention not only eliminates the uncut loop while uniformly raising the brush length without using the expensive sharing brush, but also maintains the direction of brushing, thereby making it possible to produce a high value-added brushed product economically. The present invention is to provide a method of performing the process, which will be described below with reference to the accompanying drawings.

In the drawing, reference numeral 1 denotes a roll on which the raised paper f is not subjected to the treatment of the present invention, (2) is a guide bar, (3) (4) is a tension bar, (5) is an expander, ( 6) (7) is delivery roller, (8) is the first guide roller, (9) is the first guide roller, (10) is the second guide roller, (11) is the second pillow roller, and (12) is 3 guide roller, (13) sand paper roller, (14) fourth guide roller, (15) fifth guide roller, (16) (17) tape up press roller, (18) expander, and ( F) is a brushed paper treated with the present invention.

The raised paper F, which has passed through a series of devices (processes) arranged in the above order, has a constant raising length and direction, and does not cause a change in the raising direction in the subsequent post-treatment process. The brushed paper, which has undergone pre-processing, has a constant brushing length and direction, which can greatly improve the product value.

A detailed description of each configuration of the process of the present invention configured as described above with the action and effect is as follows.

The configuration of the guide bar 2, the tension bar 3, 4, the expander 5, and the delivery roll 6, 7 is a generally known procedure. Here, the width of the raised paper is controlled by the expander 5, and the delivery rolls 6 and 7 are coated with rubber, and the lower roll 7 has a fixed shaft, but the upper roll 6 has a flow shaft and 20 with respect to the raised paper. Adjusted to apply a pressure of -90 kg / cm 2.

The most important part of the treatment (preliminary processing) process according to the present invention is located in the part from the first guide roller 8 to the fifth guide roller 15.

The needle acupuncture needle of the needle roller used in the present invention was able to confirm various test results that the following conditions showed the optimum results.

The needles have a density of 150-400 per square inch, with an outer edible angle (a) of 45-90 degrees and a broken inner angle (b) of 120-175 degrees. The needles can be sterilized in the clockwise direction (forward direction), counterclockwise direction (negative direction), or a combination thereof. The needle rollers (9) and (11) rotate in the forward direction. When the 450-900rpm negative rotation can be adjusted arbitrarily up to 3-450rpm.

Guide rollers (8) (10) (12) (14) move their positions about 5 cm above the upper tangent and about 5 cm below the lower tangent of the needle roller (9) (11) or sand paper roller (13). By controlling the contact area between the raising paper and the needle roller (9) (11) or the sand paper roller (13), the degree of treatment can be adjusted.

In addition, the fifth guide roller 15 is positioned between the sand paper roller 13 and the third guide roller 12, and the center of the upper, lower, left, and right sides of the sand paper roller 13 is about 10 cm. It is movable so that the processing area (contact area) of the raising paper in this part is adjusted.

If the needle roller (9) (11) rotates in the forward direction faster than the passage speed of the brushed paper, the brushing is laid in the opposite direction by the speed difference, and if the needle roller rotates in the negative direction faster than the passage speed of the brushed paper, The napping is then laid down in the processing direction. FIG. 2a illustrates a case where the center of the guide rollers 8 and 10 and the center of the needle rollers 9 and 11 are positioned on the same horizontal line. As shown in FIG. 8) The case where the upper end of the (10) and the lower end of the needle roller (9) (11) is in contact with the same tangent (raised) to reduce the treatment area by the needle and roller.

(c) is a case where the position of the second guide roller 10 is raised only as compared to the (a), so that the contact area with respect to the needle rollers (9) and (11) of the raised paper is wider than in the case of (a) (d). The figure illustrates the case where the first and second guide rollers 8 and 10 are raised in the same manner as in the case of (a), so that the treatment area of the raised paper by the needle rollers 9 and 11 is increased.

The two cutting needles (9) (11) are used to cut the uncut loops and remove the wrinkles, and at the same time, the brushing is arranged in a regular direction, but the following sandpaper rollers (13) and tape up press rollers The raising direction summarized by (16) and (17) can be set safely so as not to cause deformation or change of direction as in the prior art even in the post-treatment process such as coating.

By the sand paper roller 13, the raised paper not only has a buffing effect, but also a momentary shrinkage phenomenon and the curls remaining in each cut pile, thereby eliminating irregular appearance by the curls. The raising direction becomes more pronounced to improve the overall appearance. Sandpaper is suitable for 30-400 mesh so that the sandpaper roller 13 rotates in the range of 300-1,000 rpm.

The rotational speed of the lower tape up press roller 17 is related to the rotational speed of the lower delivery roller 7, and is appropriately adjusted according to the tension state of the raising paper and the feeding rate by the shrinkage. When the present invention is described in detail according to the embodiment as follows.

Example 1

The following conditions are taken in the treatment of the raised paper f in the process as shown in FIG.

(A) After tensioning and expanding the brushed paper with tension bars (3) and (4), a pressure of 50 kg / ㎠ is applied to the upper delivery roll (6).

(B) The lower delivery roller 7 is rotated at 30 m / min and the position of the guide roller, the needle roller and the sand paper roller is to maintain the same relationship as the second a degree.

(C) The needle density of the first needle roller (9) is set to 320 pieces per square inch and rotated in the forward direction such that the angle of eating is equal to 90 degrees and the bending angle is equal to 140 degrees in the forward direction.

(D) The second needle roller 11 is rotated in the forward direction under the same conditions as the first needle roller, with the angle of edible = 80 degrees and the negative angle of inclination = 135 degrees.

(ㅁ) The raising of the brushed paper is made to be in contact with the lower surface of the sand paper roller 13 by about 1/12 and about 1/18 by the upper surface of the roller 13.

(Iii) The rotation speed of the lower tape up press roller 17 is rotated about 8% faster than the rotation speed of the lower delivery roller 7.

Example 2

The first and second needle rollers were rotated in the negative direction with the angle of etched at 90 degrees and the forward angle of inclination = 140 degrees, but other conditions were treated in the same manner as in Example 1.
