Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a brushing roller used for performing so-called peach skin processing for raising ultra-short hair and high-density fluff on a knitted fabric of cotton and synthetic fiber, and Regarding a napping machine.

[Conventional technology]

Recently, demand for dress shirts and women's clothing, etc., which have been finished with a so-called peachy skin finish by giving a so-called peach skin treatment that raises fluff with a fluff length of about 0.5 to 3 mm densely with the trend toward luxury goods, has increased. ing.

Conventionally, for this kind of processing, an emery napping machine having an emery roller around which emery paper is wound is generally used.

[Problems to be solved by the invention]

However, in the prior art, since the emery paper of the emery roller is easily clogged, (1) the life is short, frequent paper rewinding operations are required, and it is difficult to improve productivity.

(2) Raising unevenness occurs in the width direction and the longitudinal direction of the cloth, and it is difficult to perform raising processing continuously with a constant finishing feeling.

There was a problem that.

The present invention has been made in view of the above-mentioned problems of the related art, and has as its object to provide a high-quality peach skin with a uniform texture over a long period of time without causing uneven brushing or clogging. An object of the present invention is to provide a raising roller for an emery raising machine and an emery raising machine which can be processed.

[Means for solving the problem]

In order to achieve the above object, the raised roller of the present invention is
Punched with hard steel wire, has many teeth with tooth tip width G of 0.01 mm or less, tooth tip thickness E of 0.05 mm or less, and base thickness of 0.3-0.7 mm A metallic wire formed into a predetermined shape is wound around a brushed roller, and the number of needles is 700
~ 1100 points / (25.4mm) ² to make the lateral pitch of the teeth dense, and the hardness of the tooth tips or teeth Hv700
Up to 900 to improve strength.

Further, in the present invention, a napping machine is configured by using the napping roller as a so-called peach skin processing roller. By the way, it is also possible to further improve the brushing performance of the metallic wire of the brush raising roller by subjecting the tooth tip or the tooth portion to a heat treatment and then performing a surface treatment such as plating or brushing.

If the number of needles is less than 700 points / (25.4 mm) ² , the density of fluff is insufficient, and if it exceeds 1,100 points / (25.4 mm) ² , the number of needles required for processing is not preferable.

〔Example〕

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

1 and 2 show an embodiment of a metallic wire used for the raising roller of the present invention.

The metallic wire (1) is subjected to a punching process using a hard steel wire to form a large number of teeth (3) (for example, 17 ridges / 25.4 mm) on the upper portion of the base (2).

In the embodiment, the metallic wire (1) has the same angle X.
63 °, tooth depth B 0.5 mm, base (2) thickness C 0.5 mm,
The tooth tip width G was set to 0.01 mm or less and the tooth tip thickness E was set to 0.05 mm or less. The same angle X was 55 ° to 120 ° and the tooth depth B was 0.3 to 0.3 mm.
1.0mm, base thickness C is about 0.3 ~ 0.7mm, number of peaks is 15 ~ 30
A range of ridges / 25.4 mm is suitable for peach skin processing.

The metallic wire is more effective when its dimensions are selected within the above range according to the type and texture of the processed material. Also, at least the tip (4) of the metallic wire (1) is quenched to reduce the tip hardness to Hv.
The strength is improved to 700-900, and surface treatment such as plating and brushing is performed to smooth the tooth tip surface and prevent unnecessary fibers from jumping out during raising.

Next, the metallic wire (1) is wound around a roller having a required diameter, and the number of needles is 700 to 1,100 points / (25.4 mm).
A raised roller (R) having ² is formed. The raising roller (R) is arranged, for example, as shown in FIGS. 3 and 4 to constitute a raising machine.

By the way, with a raising machine provided with the raising roller (R), the plain woven fabric for shirting is raised (cloth speed: 10 m / min,
Roller rotation speed: 1,000r, p, m), the tooth tip of the metallic wire (1) on the roller surface acts to rub the fabric surface, resulting in extremely short hair (fuzz length 0.5-3mm), and Peach skin processing with high-density fluff was achieved.

Comparing this example with that of a conventional emery napping machine, it was found that a slimy feeling and an excellent texture with a fuzz density equal to or higher than that were obtained.

By the way, the raising roller of the above-mentioned embodiment can be used not only for a multi-operation type raising machine or a napping machine, but also, after the above-mentioned raising, there is a case where the hairs are made to have the same fluff length.

〔The invention's effect〕

Since the present invention is configured as described above, the tooth height accuracy can be suppressed to about ± 2/100 mm, and clogging does not occur. It does not occur, and the fluff of the extremely short hairs is dense, so that brushing with a slimy feel can be obtained. In addition, it has excellent effects such as stable brushing over a long period of time, a significant reduction in the number of man-hours required for rewinding, and an improvement in productivity.
