Description

  The present invention relates to a wiping dust removing cloth used for pre-cleaning a surface to be painted such as an automobile.

  As the wiping dust-removing cloth, a base cloth having flexibility, which is preliminarily provided with an adhesive such as oil or resin, is known (see Patent Document 1). The pressure-sensitive adhesive is used for attaching dust so that the surface to be painted of an automobile or the like is not scattered in the air.

By the way, as said base fabric, it divides roughly into the following two. The first base fabric is obtained by cutting a short-fiber woven or knitted fabric made of natural fibers such as cotton or synthetic fibers such as polyester into a predetermined size. The second base fabric is obtained by folding a long fiber fabric made of synthetic fibers such as polyester into four with both ends thereof inside and cutting the fabric in the length direction.
JP-A-7-231870

  However, since the first base fabric is a short fiber, there is a drawback that yarn waste falls off from the woven fabric or knitted fabric. In addition, since the second base fabric is a woven fabric using long fibers, there is a problem in that the filament falls off from the cut end and yarn waste occurs.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a wiping dust removing cloth capable of suppressing the generation of yarn waste.

The wiping dust removing cloth according to the invention of claim 1 is a wide knitting obtained by raschel knitting long fibers made of synthetic fibers or processed yarns thereof, or tricot knitting long fibers made of synthetic fibers or processed yarns thereof. Using a cut fabric of a predetermined width obtained by cutting the fabric in the width direction, the cut fabric is folded in four with the width direction both ends in the middle, and is melted by an impulse fusing device in the length direction and a fusing terminal is welded. It is formed, and the width direction opposite side to the width direction edge part in which the said width direction both ends located inside by folding into four is opened, It is characterized by the above-mentioned.

  The wiping dust-removing cloth according to the invention of claim 2 is characterized in that a width dimension of the four-folded cloth is 10 cm or more and 45 cm or less.

  The wiping dust-removing cloth according to the invention of claim 3 has a pressure-sensitive adhesive for dust adhesion.

  In the case of the first and second aspects of the invention, there is no filament breakage due to knitting by Russell knitting or tricot knitting, and yarn waste (lint) is lost due to the knitted fabric even if it hits a burr when wiping the coated surface of an automobile or the like There is no. Furthermore, since the fused end is welded, there is no drop of yarn waste, and in addition, both ends of the cut fabric cut in the width direction are folded in, so that there is no yarn waste drop even when hitting a burr. In particular, in the case of claim 2, a wiping dust removing cloth having a width dimension generally used is obtained.

  In the case of the invention of claim 3, the dust which wiped off the surface to be coated of an automobile or the like can be adhered to the adhesive so as not to be scattered in the air.

  The present invention will be specifically described below.

(Basic configuration of the present invention)
FIG. 1 shows a knitted fabric 2 obtained by Russell knitting long fibers made of synthetic fibers. FIG. 1A is a front view of the knitting fabric 2, and FIG. 1B is a side view of the knitting fabric 2. The knitted fabric 2 is a fabric of a certain size, for example, having a width dimension W1 of 10 cm to 45 cm, and is sent while being knitted in the longitudinal direction L thereof. Then, it is blown to a predetermined length by the impulse fusing device 3 provided at a predetermined position, so that the wiping dust cloth 1 is obtained. The reason why the width dimension W1 of the knitted fabric 2 is set to 10 cm or more and 45 cm or less is to obtain a wiping dust removing cloth 1 having a generally used width dimension.

  As shown in FIG. 2, the knitted fabric 2 has a warp knitting structure in which the ends of the loops are connected to the upper course, and has no yarn ends at both ends in the width direction. In addition, as the knitting fabric 2, the thing which carried out the Russell knitting of the processed yarn of the long fiber which consists of synthetic fibers is included.

  The impulse fusing device 3 is provided with a receiving plate 3a and a fusing portion 3b with the knitting fabric 2 sandwiched from both the front and back sides, and the receiving plate 3a and the fusing portion 3b have a width W1 of the knitting fabric 2. Have a slightly longer dimension. In this basic configuration, the receiving plate 3a is fixed, the fusing part 3b is configured to be in contact with and separated from the receiving plate 3a, and a pulse current is supplied to the fusing part 3b for a certain period of time. The knitted fabric 2 is pressed against the receiving plate 3a, and the fusing part 3b moves away from the receiving plate 3a after a lapse of a certain time after the supply of the pulse current is completed.

  The fusing of the wiping dust-removing cloth 1 by the impulse fusing device 3 is performed by pressing the fusing part 3b heated by the supply of the pulse current toward the receiving plate 3a and thereby separating it from the knitted fabric 2. Then, the fusing terminal of the blown wiping dust cloth 1 is cooled with the end of the supply of the pulse current while the fusing part 3b presses the fusing part of the wiping dust cloth 1, and then the wiping dust is removed. Since it leaves | separates from the fusion | melting part of the cloth 1, it is set as the state welded. In addition, since the other one terminal is already welded similarly, both the terminals of the obtained wiping dust cloth 1 will be in the welded state.

  Therefore, the wiping dust-removing cloth 1 of this basic configuration is welded at both ends fused by the impulse fusing device 3 and both ends in the width direction are raschel knitted stitches themselves (there is no yarn end). In all four sides of the wiping dust-removing cloth 1, there is no drop of yarn waste. In addition, there is no filament breakage due to knitting by Russell knitting with little friction, and even if the surface to be coated of an automobile or the like is wiped off when hitting a burr, there is no yarn scraping (lint) dropout due to the knitted fabric.

  In addition, by adopting a configuration in which the wiping dust removing cloth 1 is impregnated with an adhesive, such as oil, resin, or fat wax, etc., the adhesive prevents wiping off the surface to be painted such as an automobile from being scattered in the air. Can be attached. Needless to say, the pressure-sensitive adhesive includes those other than the above that can adhere to dust.

(Embodiment of the present invention)
Embodiment of this invention is a case where a wiping dust removal cloth is produced using the knitting fabric of the width dimension longer than the width dimension of a wiping dust removal cloth.

  As shown in FIG. 3, the fabric has a wide width W2 obtained by raschel knitting long fibers made of synthetic fibers or processed yarns thereof, or tricot knitting long fibers made of synthetic fibers or processed yarns thereof. A knitted fabric 2A is used. Then, the knitted fabric 2A is cut in the width direction, and is cut at two places in the illustrated example. As shown in FIG. 4A, the width dimension W3 (≈W2 / 3) is 40 cm or more and 180 cm or less. Make the cut fabric 2B of dimensions. The longitudinal direction L of the cut fabric 2B coincides with the knitting direction of the knitting fabric 2A. Subsequently, as shown in FIG. 4B, the cut fabric 2B is folded into four with the width direction both ends a0 in the middle, and a fabric having a certain dimension W4 (≈W3 / 4) having a width dimension of 10 cm to 45 cm. 2C. In the obtained fabric 2C, the folds a1 and a2 at the intermediate portion in the width direction of the cut fabric 2B before being folded are both ends in the width direction.

  The crumpled cloth 2C obtained in this way is melted in the length direction by the same impulse fusing device 3 as before, and the wiping dust cloth 1A on which both ends in the longitudinal direction L are welded is obtained. Form. FIG. 5 shows a full tricot knitting stitch as an example of the tricot knitting. This full tricot knitting also has a warp knitting structure in which the ends of the loops are connected to the upper course as in the case of the Russell knitting described above, and has a structure having no yarn ends at both ends in the width direction. Although not shown, the same applies to other tricot knitted fabrics such as three-piece tricot knitting.

  Therefore, the wiping dust removing cloth 1A according to the embodiment of the present invention has no filament breakage due to knitting by Russell knitting or tricot knitting, and is also knitted because it is knitted even if it hits a burr when wiping the coated surface of an automobile or the like. (Lint) No dropout. Furthermore, since the ends fused by the impulse fusing device 3 are welded, there is no drop of yarn waste, and in addition, both ends of the cut fabric cut in the width direction are folded inside, so even if it hits a burr, the yarn There is no waste removal.

  Moreover, the dust which wiped the to-be-painted surface, such as a motor vehicle, in air | atmosphere by setting it as the structure which impregnated the adhesive to the wiping dust removal cloth 1A of embodiment of this invention similarly to the basic composition of this invention. It can be attached to the adhesive so that it does not scatter.

  In the above-described embodiment of the present invention, the impulse fusing device has a structure in which the receiving plate is fixed and the fusing part is in contact with and separated from the receiving plate, but the present invention is not limited to this. For example, an impulse fusing device having a structure in which the backing plate and the fusing part are brought into contact with or separated from each other, or an impulse fusing apparatus having a constitution in which fusing parts to which a pulse current is supplied on both sides of the cloth are arranged may be used.

  Further, the present invention provides a fusing and welding apparatus capable of separating the wiping dust cloth by fusing the dough and welding both ends of the wiping dust cloth instead of the impulse fusing apparatus described above, for example, a welding portion having a constant width. It is also possible to use a fusing and welding apparatus or the like configured to cut the middle position of the welded portion.
