Abstract

(57) [Abstract] [Purpose] The efficiency of cutting and brushing is high, and its performance is maintained for a long time. [Structure] The cross-sectional shape of the needle tip is formed such that the working side surface is an arc having a radius of curvature larger than that of the back side surface, and both side surfaces are substantially parallel to each other and become gradually smaller in a substantially similar shape toward the needle tip. . Further, the dimension b between the side surfaces of the needle tip portion at a position of ¼ to ⅕ of the total height of the needle from the needle tip is b ≦ 2 / 3B (B: width in the short axis direction of the needle).

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a raised needle cloth used in a raising machine for raising the surface of a cloth.

[0002]

[Prior Art]

 In the conventional brushed needle cloth, a needle cloth wire having a cross-sectional shape such as a substantially elliptical shape, a substantially track shape, a substantially rhombic shape, etc. is bent into a substantially U shape in the minor axis direction, and needles are planted on the base cloth. The needle protruding inward is bent into a dogleg shape, and the side surface of the needle tip is made into a long blade shape, and the needle tip is ground into a needle shape.

[0003]

[Problems to be solved by the device]

 By the way, in recent years, with the trend toward higher grades, attention has been paid to the nap processing of textile products, and in particular, there is a demand for a napped needle cloth suitable for a cut nap for finishing a fine denier material fabric in a suede tone.

However, in the conventional brushed needle cloth, as shown in FIG. 4, the cross-sectional shape of the needle tip portion 11 of the needle 10 is such that both side surfaces are substantially eight-shaped and the working side 12 has an arc length l. Since it was formed in a shape longer than the side surface 13, it was difficult to pierce into a fine denier fiber bundle, and the efficiency of cutting and brushing was poor. Further, as shown in FIG. 5, since the rate of increase in the cross-sectional area of the needle with respect to the distance from the needle tip at the tip of the needle was large, the cross-sectional area was greatly increased by the polishing needle, and the raising efficiency was significantly reduced.

In view of the above-mentioned conventional techniques, the present invention provides a raised needle cloth which has a high efficiency of raising the cut, has a small increase in the cutting area due to the polishing needle, and can maintain the high-efficiency cut raising for a long period of time. The purpose is to do.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the brushed needle cloth of the present invention has a needle cloth wire having a cross-sectional shape such as a substantially elliptical shape, a substantially track shape, or a substantially rhombus shape, which is planted on the base cloth so that the major axis side is the working side. In addition, in the case of brushed needle cloth with the side surface of the needle tip part made into a substantially sword shape, the cross-sectional shape of the needle tip part should be such that the working side surface is an arc with a radius of curvature larger than the back side surface and both side surfaces are substantially parallel. The height h from the base A of the needle tip to the needle tip h = (1/4 to 1/5) H (H: needle) The total height), and the dimension b between both side surfaces of the base A is b ≦ 2 / 3B (B: width in the short axis direction of the needle). In addition, the ridge line at the intersection of the above-mentioned working side arc and both side surfaces is formed into a sharp edge.

[0007]

[Action]

 When the brushed needle cloth configured as described above is mounted on the brushing machine and the fine denier material is brushed, the needle tip is pierced into the cloth, the cloth is efficiently cut and brushed, and the needle tip is polished. The cross-sectional area does not increase even when the above procedure is performed, and excellent brushing efficiency is maintained for a long period of time.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, a raised needle cloth 1 according to the present invention comprises a base cloth 2 and needles 3 implanted in the base cloth 2. The base cloth 2 has a surface layer 2a made of a sheet of rubber, sponge, felt or the like and a base layer 2b made by laminating a plurality of woven cloths such as cotton cloth, linen cloth or synthetic fiber cloth, or a rubber sheet. It is made by pasting together with an agent.

The needle 3 is formed by bending a needle cloth wire having a substantially elliptical cross-sectional shape into a substantially U-shape in the minor axis direction to implant the needle on the base cloth 2 and project it onto the base cloth. The bent portion is bent into a substantially V shape at a predetermined angle. The cross-sectional shape of the needle tip 4 of the needle 3 acts so that the radius of curvature R of the arc of the side surface 6 and the radius of curvature r of the arc of the back side surface 7 satisfy the relation R> r, and both sides are polished by side surface polishing. 8 and 8 are substantially parallel to each other, and the dimension b between the both side surfaces 8 and 8 of the base portion A of the needle tip portion 4 is formed to be a flat shape in which the dimension B is 2/3 or less of the width B of the needle 3 in the short axis direction. .. The base portion A is set at a position corresponding to a height h of 1/4 to 1/5 of the total needle needle height H from the needle tip 5 having a needle shape.

Further, sharp edge-shaped ridge lines 9 and 9 are formed at the intersections of the working side surface 6 and both side surfaces 8 and 8. The back side surface 7 and the both side surfaces 8, 8 are preferably connected by a smooth curve. Further, the side surface of the needle tip 4 is formed into a substantially sword shape, and is gradually reduced in a substantially similar shape from the base A toward the needle tip (FIG. 3).

By the way, in the above-mentioned embodiment, the needle laying wire may have a substantially track shape or a substantially rhombic cross-sectional shape other than the substantially elliptical shape.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to efficiently perform raised brushing even for fine denier material fabrics, and the raised efficiency does not decrease even with a brush, so that highly efficient cut raised hair can be maintained for a long period of time. It has the effect that it can be maintained.
