Description

The present invention relates to a felt manufacturing method characterized in that the cross section is composed of a multicolor layer.

Felt is generally used as household goods, office supplies, industrial products and the like. The felt itself is made by laminating and shrinking natural fibers, chemical fibers, and synthetic natural fibers, or needle punched into a single sheet, but the cross-section is the same color as the surface, and is a single color. is there. When a colored felt material is required, a felt material having a desired color has been made by post-dying the sheet-like felt with a dyeing machine. These colored felts are widely used as handicraft materials such as a hair thread, a calligraphy thread, and an applique.
In order to obtain felts with different colors formed on different surfaces, multicolor artistic design felts by temporarily fixing fibers of a different color from the substrate on the substrate and passing through a felt machine There is a case where a cloth that has been turned into a cloth is obtained (Patent Document 1).

In addition, one sheet-like felt having different colors has different colors on the front and back. This is to prepare a felt with different colors from the front by preparing one felt for the front and different colors from the front for the back, and obtaining both sides with a punch needle to obtain a felt with different colors It is. In other methods, overlapping different color fibers in the two layers to each other, by reduced charge processing, the color of the felt sides are different is obtained.
Conventionally, there is a technique in which a pattern is expressed by cutting a felt made of eight layers of three colors of white, black, and gray (Patent Document 2).

However, the thing of patent document 1 obtains the design of the fixed hue, and the change of the color in a felt layer cross section cannot be obtained. In addition, the felt had an image of a single color, and there was no felt having a multi-colored cross section.
In addition, as in Patent Document 2, in the past, the wrap is reduced by using eight layers of three different colors , but how to specifically manufacture felt by reducing three or more colors. It was not known . This is because there is no need to change the color in the conventional felt, and there was no idea to obtain a felt having a multi-colored cross-sectional layer because the post-dyeing was mainly used even with a dyed felt. is there.
In addition, there is a drawback that a large amount of edge cracks (so-called “ears”) generated by cutting the end portion during manufacture become a rebuffed product or a discarded product.
The present invention solves these problems, in which cross-section is intended for manufacturing process of five or more layers of the multicolor layer felt.

The present invention has been made in order to solve the above-mentioned problems, and provides a method for producing a felt having a multicolor cross-sectional layer whose cross section is composed of a number of color layers.
The method for producing a felt having a multi-color cross-sectional layer according to the first invention, dyes a plurality of fibers so that the colors are different from each other in advance,
Next, each of these fibers in a wrap state is formed into a sheet state, and then wound around a roller, supplied onto a harder board of a compacting machine, and each sheet is stacked and contracted to reduce the multicolor layer felt. After creating
The surface of the multicolor layer felt, cut into two hemispheres several times repeating the steps of forming a recess, and wherein the Rukoto obtain felt whose coloring sectional layer.

The method for producing a felt having a multicolor cross-sectional layer according to the second invention is characterized in that, in the first invention, the number of the fiber layers to be stacked is five or more.

The present invention is previously fibers dyed in different colors 5 or more, by manufacturing the felt by stacking and to obtain a multi-color full Eruto without dyed conventional as machining.
Since the cross section of the felt of the present invention is composed of a multicolored layer, it is possible to obtain a felt having a color change that has not occurred conventionally. Further, the felt of the present invention can be used for various products such as carpets, building materials, wall materials, coasters, vases, cushions, tapestry, rugs, partitions, toys and accessories. In addition, since the felt of the present invention makes use of the color of the cross section, the end of the manufactured felt does not necessarily have to be cut at a right angle to form a straight line, and is generated at the time of processing the end during manufacture. The amount of cut parts (ears) to be discarded is significantly reduced. In addition, the ear part can be used as a design product.

Embodiments of the present invention will be described below.
First, in order to explain the invention in an easy-to-understand manner, the simplest example will be described. As shown in FIG. 1, fibers a, b, and c previously dyed so as to have different colors (weight per unit area 2130 g / m ^{3 to} 2233 g / m ³ , fiber thickness 60/64 (24 microns)) A, B, and C having a predetermined wrap state are prepared. In the wrap state, since the fibers are gathered and lightly formed into a sheet, the surface is not flat, but in FIG.
The above A, B, and C are not necessarily the same fiber (for example, a wool fiber, a blend of wool and rayon), and may be fibers that can be easily contracted, and if the colors are different from each other. Good. The degree of color difference is not limited to different colors as long as the hue of the same color is different (for example, the gradation should be different, such as light red and dark red).

  The above A, B, and C are each formed as a wrap, and then wound around a roller. The wrap is sequentially supplied from each roller onto the harder board of the compacting machine, and the compaction is performed.

After contraction, the adjacent layers of A, B, and C are intertwined with each other due to pressure due to contraction. As shown in FIG. 3, the cross section of the multicolored felt shows the colors of the fibers constituting A, B, and C, respectively. The surface is a single or mixed color of A and B, and a mixed color of B and C.
In addition, when creating wraps, if pre-dyed fibers of different colors are arranged in a quilt shape, the surface color after shrinking will be multicolored with various colors appearing in the quilt shape. Can be obtained.
The manner in which the color appears varies depending on the pressure, the degree of eccentricity, the fir time, etc. during the reduction process, but the greater the amount, the greater the degree of mixing of the three colors of the A, B, and C layers.

The above description is an example in which wraps are overlapped on the simplest three layers. However, as shown in FIG. 4, the wraps of 12 layers of A, B,... In the same manner, the cross section of the completed multi-colored layer felt has a more complicated color pattern than the case of three layers. In this case, depending on the color of each wrap and the conditions of contraction, it is possible to make the color where adjacent layers of 12 colors intermingle appear clearly in the cross section. In consideration of the gradation of the color of the wrapped wrap, the color pattern of the cross section is not necessarily 12 layers, but different colors of adjacent wraps are mixed, and the layered pattern is composed of fewer than 12 colors as a whole. Appears out of order (FIG. 5). Further, the hardness of the completed felt can be adjusted by changing the condition of contraction. For example, the felt can vary from a fluffy one to a hard one.
In the inventor's experiment, the number of layers of laps to be overlapped was from 5 layers (ie, 5 colors) to 48 layers (ie, 48 colors). Can be increased.

  Examples will be described. The material used is 100% wool. Speaking in order of overlap, yellow, orange, green, dark gray, generated, blue, yellow, orange, green, blue, generated, each consisting of two layers of wrap, in between the three layers of chocolate wrap A wrapping layer consisting of 13 layers of 7 colors in total was superposed and condensed. This overlapped lap is about 30 mm thick and about 1900 mm square, with a compaction pressure (excent, that is, the eccentric width of the rotating shaft) of 9, a fir time of 9 minutes, and a hot plate temperature of 40 ° C to 45 ° C. Shrink while supplying water and steam. After shrinking, the wrap thickness was 7.4 to 8.5 mm.

Next, an example of processing the multi-colored layer felt created as described above will be described.
FIG. 6 is a view showing an example of processing a multi-color layer felt, and shows a cross-sectional view thereof. Fig. 6 (a) shows the surface of a multi-colored layered felt made of 7 layers (7 colors) of wraps A, B, ..., G, which is condensed and formed into a hemispherical shape, thereby forming recesses 11. It was made. As shown in FIG. 6 (b), the concave portion 11 is a view seen from the direction of the upper arrow in FIG. 6 (a), and each layer of wraps A, B, C,. When the concave portion 11 is viewed from above, a color pattern composed of C, D, E, F, and G colors appears. In order to make it easy to understand, in the figure, it is drawn in a ring shape, but the actual visible pattern can be freely changed according to the condition of contraction, the color of the wrap, and the thickness of the wrap. In addition, by providing a plurality of the concave portions 11 on the felt surface of the multicolor layer, or by changing the size and depth of the concave portions, it is possible to obtain a color pattern with changes. This can be used as a cushion or a wall material, for example.

  In another processing example, as shown in FIG. 7 (a), the created multicolored felt may be cut into a spherical shape to create the raised portion 12, in which case, as shown in FIG. 7 (b). You can see a large ring-shaped pattern from the top. The size of the spherical raised portion 12 can be freely made. In addition, you may cut the surface of the multicolor layer felt on a plane, and may provide the protruding part which changed the magnitude | size on the surface, or the protruding part of the same shape. These can be used for, for example, rugs, wall materials, cushions, interiors, and miscellaneous goods.

Although the said example of a process was shown, it is also possible to process combining these recessed part and a protruding part.
The multi-colored layer felt that cuts only the end portion on the slope and does not process the surface has a gentle end portion, so that it is difficult to trip, and in this case, it is particularly effective as a rug.

  As the material for multi-colored layered felt, natural fibers such as wool, cashmere, silk, hemp, etc., or synthetic fibers such as polyester and rayon, which are produced or dyed, are used singly or mixed, and multiple wraps of different colors are used. Prepare a sheet. This is wrapped and wound around a roller. One sheet is pulled out from the rollers of each of the laps in the contraction process, and the desired number of sheets are stacked and contracted. (This process is the same as the conventional shrinking process)

In the present invention, a variety of color patterns can be obtained by blending the raw material colors (any color can be changed by changing the gradation).
In the above, the multi-colored layer felt was created by contraction, but the fiber layer was pierced with a needle punch needle against the stacked layers of the wrap layer using a needle punching process. It is also possible to entangle and make a multicolored felt.

It is a principle explanatory view of the present invention which obtains a multicolored felt by overlapping three layers of wraps. It is an enlarged view of the multicolor layer felt which consists of three layers obtained by shrinking | reducing. It is the figure seen from the X direction of FIG. It is a figure which shows typically the wrapping layer of 12 colors from which the color of this invention differs. It is a figure which shows typically the cross section of the multi-colored layer felt obtained from 12 wraps. It is a figure which shows the multicolor layer seen by making the concave part by making the hemispherical surface of the multicolor layer felt. It is a figure which shows the multicolor layer seen by creating a raised part from a multicolor layer felt, in that case.
