DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raising machine for a fiber cloth.

[0002]

2. Description of the Related Art Conventionally, a single-acting napping machine or a double-acting napping machine of a type in which a plurality of rotating napping cloth rolls are arranged on a rotating napping drum obtains various hair products. Therefore, it has been widely used in various fields.

[0003] In recent years, it has been frequently practiced to raise a fabric made of long synthetic fibers as a suede-like material, and there is a demand for a napped fabric having short fluff and sufficient fluff density. More recently, the use of needles for the base fabric of synthetic leather made of thin synthetic fabrics such as skin-touch and peach-touch with particularly short fluff, such as so-called skin touch or peach touch, and fabrics made of ultra-fine fibers. There has been a demand for a delicate napped fabric obtained by a combination of rubbing treatment with an emery processing machine after raising the cloth.

[0004]

However, in conventional single-action napping machines and double-action napping machines, a needle cloth roll is used as a napping roll, and is mainly intended for fabrics made of short fibers of natural fibers. Since it has been made, when raising a fabric made of synthetic fiber long fibers, the nap is often prolonged or the nap density is insufficient, so that suede-like short fluff is densely spread on the surface of the fabric. It was difficult. In particular, it is difficult to make fluffs shorter than the suede tone such as skin touch and peach touch densely on the fabric surface or to make a delicate napping fabric for a base fabric of synthetic leather with a conventional napping machine composed of a needle cloth roll. , It was even more difficult.

Therefore, in order to obtain such a fabric having particularly short fluff, a rubbing treatment with sandpaper or the like must be performed using an emery processing machine. However, a conventional emery processing machine is mounted on a fixed base. In this method, it is difficult to control the contact pressure between the emery roll and the fabric and the number of rotations of the emery roll. It was necessary to apply a large tension in the length direction to the cloth to perform the rubbing treatment. However, in such a rubbing process, unevenness in the form of a stripe due to high tension in the length direction occurs, and band-like unevenness in the horizontal direction (tiger step) due to unevenness in the tension in the length direction, etc. The fabric surface could not be uniformly treated.

Accordingly, the applicant of the present invention has proposed in Japanese Patent Application No. 63-317235 a brushing method using an emery roll in which a needle cloth is removed from all or a part of the brush roll and emery paper is wound. Although the part has been improved, it is still insufficient for fabrics made of ultra-fine fibers.

[0007] The present invention has been made in view of such circumstances, and does not cause unevenness such as skin touch and peach touch on a cloth made of ultra-fine fibers without causing unevenness in the shape of a stripe or a band. It is an object of the present invention to obtain a raising machine capable of uniformly growing naps shorter than a suede tone on a fabric surface.

[0008]

The present invention attains the above object and has the following constitution. That is, the present invention relates to a single-action napping machine or a double-action napping machine in which a plurality of rotating napping rolls are arranged on a rotating napping drum. The gist of the present invention is a napping machine characterized by being constituted by an emery roll on which sandpaper is wound. Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic side view showing a main part of a napping machine according to the present invention. In the drawing, a cloth 1 passes through a cloth feed roll 2, is rubbed by emery rolls 9, 10 provided on a raising drum 8, and then is a cloth pull-out roll 3,
After passing through 4, 5, and 6, it is shaken down by a swinging roll 7 onto a cart or a timing device (not shown).

A conventional brush for raising a brush in a single-acting or double-acting type napping machine is a clothing roll. The present invention is based on such a completely new concept that hits the blind spot of the conventional common sense, and uses a raising roller other than a needle cloth roll, that is, an emery roll as a pile roller 9 and a counter pile roller 10 as a raising roll of a raising machine. To raise the brush. Here, the emery roll is formed by winding sandpaper or the like on the needle cloth of a conventional needle cloth roll, and the particle size of the sandpaper or the like is in the range of # 40 to # 2000 according to the desired fuzziness. It can be selected as appropriate, especially on thin fabrics with a basis weight of about 100 g / m ^2.
# 800 is preferable, and # 60 to # 600 is preferable for a medium-weight material having a basis weight of about 200 to 300 g / m ² . The emery roll is simply made by winding sandpaper or the like on the needle cloth of the needle cloth roll, so that the emery roll can be easily and directly attached to the mounting portions of the pile roller 9 and the counter pile roller 10 of the napping machine. .

[0011] In the case of performing the raising treatment for the base cloth of the synthetic leather made of ultra-fine fibers by the raising machine in which the emery roll obtained by winding the sandpaper on the needle cloth is provided on the raising machine, Since the device itself is a rubbing treatment with an emery roll, there is no inconvenience that the woof of the woven fabric cannot be raised unless the weft of the woven fabric is floating, as in the case of the napping of the needle cloth. It can be brushed and raised on fluff. Further, according to the present raising machine, the number of the emery rolls 9 and 10 is larger than the number of rolls of about 1 to 10 of the conventional fixed type emery raising device, for example, 24 to 30 in a normal raising machine, and The contact pressure (drum tension pressure) between the fabric 1 and the emery rolls 9 and 10 and the number of revolutions of the emery rolls 9 and 10 can be freely adjusted in the same manner as in the case of performing the brushing of the needle cloth. From the so-called zero-point napping to strong napping, napping can be freely adjusted and napping is possible. Can be completely eliminated.

When the emery roll is mounted on the double-type raising machine, the emery roll is mounted on both the pile roller side and the counter pile roller side. At this time, the ratio of the number of the pile roller and the counter pile roller mounted is shown in FIG.
As described above, in addition to 1: 1, it can be appropriately changed to 1: 2, 1: 3, 1: 4, or the like as needed. Alternatively, the emery roll can be attached to one of the pile roller side and the counter pile roller side, and the other can be used as a needle cloth roll to combine needle cloth raising and rubbing. Further, if necessary, it is also possible to perform the same napping treatment while leaving one or both of the pile roller side and the counter pile roller side as needle cloth rollers.

The particle size of the sandpaper or the like wound on the needle cloth does not need to be the same for all emery rolls, and the particle size of the emery roll on the pile roller side and the particle size of the emery roll on the counter pile roller are appropriately changed. However, even when the particle size is changed between the emery rolls on the same pile roller side or the counter pile roller side, good rubbing treatment can be performed.

[0014]

According to the present invention, when emery paper is wound on a garment, the cushioning effect of the needles of the garment absorbs the elongation of the emery paper due to moisture absorption and the like, so that uniform raising can always be achieved. In addition, when the napping machine of the present invention is used for napping a fabric made of ultra-fine fibers that require delicate napping, the thickness in the width direction is uniform due to the cushioning effect of the needles of the garment, and the fluff density is high. Good brushed quality can be obtained.

[0015]

The present invention has a structure in which an emery roll made of sandpaper wound on a needle cloth is disposed on a normal needle cloth raising machine. According to the report, naps such as skin touches and peach touches that are shorter than suede-like short naps and delicate naps for synthetic leather base fabrics made of ultra-fine fibers can cause unevenness in the shape of a tapestry or band. And can be densely grown on the surface of the fabric. In addition, it is also possible to eliminate defects of poor reproducibility of the napped state, such as non-uniformity of napped brushes and unevenness of width in the width direction, which were disadvantages of conventional emery napped brushes, as well as tangs.
