Abstract

PROBLEM TO BE SOLVED: To solve the following problems induced by the conventional problem that creases or pleats on cloths easily disappear: in other words, the place to be pleated or creased has to be located; in diaper, it is circular and tends to tangle with each other after washing or drying; the tangled ring must be loosened into a sheet and then dried or folded; a handkerchief, a pair of trousers or a white shirt has to be ironed only for forming folding lines, even when there is no wrinkle; the material sensitive to heat cannot be ironed. SOLUTION: In the case that fabric 1 such as diaper, towel or clothe is needed to have fold lines formed, the fabric is bent at the place to be folded and the fabric is sewed up along the fold line thereby giving the fold line. The stitching line becomes the mark 2 for the folding line and the fold line can be held as long as the stitching line remains.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for creasing fabrics, such as diapers, towels and clothing.

[0002]

2. Description of the Related Art Creases have been made using irons or permanent presses. In order to make the fold, the fabric was folded by giving it a fold.

[0003]

In the conventional method, there is a problem that the fold disappears when the cloth is used or washed. In the case of diapers and towels, the creases are particularly easy to disappear, so even if you try to fold them after washing and drying, there is no indication of where to fold. Furthermore, the folds disappeared after washing and drying, so it was necessary to make a new fold by pressing firmly by hand or ironing. In the case of towels that are often used in beauty salons and baths, they are often folded in fours. First of all, to find a place to make a crease, lift both ends up with both hands to find a half, and Place on top and fold in half. Furthermore, it was folded in half, and the edges were overlapped and folded in four. In the case of diapers, as the baby grows, it is folded in three in addition to four. In the case of three-fold, it is more difficult to determine the place where the fold should be made than in the case of four-fold. He relied on his experience and intuition to fold the eye around one-third, but needed fine-tuning to open and fold again. It was difficult to fold in the darkness and other blind situations. Also, diapers are often entangled after washing or drying because they are ring-shaped. It was necessary to unwind the entangled ring and make it into a sheet, and then hang and fold it. When folding, it was necessary to find a place to make a fold with intuition and then press it down further to make a fold. In the case of handkerchiefs, pants and shirts, even if there were no wrinkles, it was necessary to iron only to make a crease. Heat-sensitive materials could not be creased with an iron. Materials with low flexibility, such as steel, plastic, and leather, may be cracked when bent, resulting in impaired conductivity, insulation, protection, appearance, and the like. A net or a wire net is difficult to be creased, and the strength of the bent portion may be significantly impaired.

[0004]

After a portion where a fold is to be made is bent, the fold is sewn along the fold. Then, even if the clothes are washed, the crease is not erased because the fabric is kept folded. At this time, since the seam line or the periphery of the margin is bulged up, it becomes a mark of a place to be folded. This sign can be felt by touching the climax unlike a sign attached with ink or the like. Thus, even in situations where blind vision cannot be relied upon, it is possible to find the place to fold by tactile sensation. Furthermore, the folds are sewn together in the direction in which the folds should be folded, but since the folds are fixed by sewing, the folds will not disappear unless the stitches are released.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION After folding a portion to be folded, a seam is formed along the fold with a sewing machine or the like as shown in FIG.

[0006]

When applied to a towel, it can be spread out and hung on a hanger when it dries. In many cases, such as a beauty salon or a hospital, a large number of sheets are handled, so that the folding time after drying can be reduced. If performed on diapers,
In addition to the advantages of applying to a towel, it also has the effect of preventing tangling of the fabrics in the washing machine / dryer. It is necessary to prepare four-fold folds and three-fold folds with the growth of infants, but this can be said to be an advantage from the standpoint of a diaper manufacturer or the like in that it leads to an increase in the number of sales. It also matches the original intent of the patent to contribute to industrial development. In the case of handkerchief folds, the handle often has front and back sides, but if the folds are made in advance, the trouble of visually checking the front and back sides when folding is eliminated. When performed on the fold of the pants, the fold can be held as long as the seam is not broken. The effect of preventing wrinkles is not strong, but a trouser press is unnecessary at least for the fold. This is convenient when you can't use an iron or the like while traveling, because you don't need to worry about the folds disappearing.
When applied to the folds of the shirt, the form-stable shirt can prevent wrinkles but cannot retain the folds. Therefore, the present invention is useful for making a strong crease. When the fold is made on the skirt, it is difficult to find a place to fold the pleat or tuck if the fold disappears, but the fold does not disappear if it is sewn and fixed. When applied to curtain folds, the upper edges need not be overlapped and sewn as in the conventional case. The larger the curtain, the less frequent the ironing is because it is difficult to handle, but according to the present invention, the folds can be retained for a long time. When the present invention is applied to outdoor equipment such as a tent and a sleeping bag, it is possible to easily determine a place and a direction to be folded even in the dark. Also, it is convenient because it does not require a power source or a heat source like an iron. When it is applied to a product made of cloth that is deformed by heat, such as vinyl, it does not require heat like an iron, so there is no need to worry about melting or deformation. When the method is applied to a heat-sensitive fabric, it may be welded instead of stitching by utilizing its properties. When making a fold, an electric sewing machine is not always necessary. Since it can be creased even with a step sewing machine or hand sewing, it can be creased even when there is no energy source such as electricity or heat. Since the shape is slightly different from the fold of the iron, it can be applied to fashion as a design. Even if the material has low flexibility, such as steel, plastic, or leather, it does not break with the packing at the bent portion, nor does the surface layer crack or come off. Since it can be handled as one, it can be creased without losing properties such as conductivity, insulation, protection performance, and appearance. This is due to the fact that it is not necessary to bend, that is, a fold can be formed even when sewing is performed with an appropriate curvature and radius. It can also be used to make folds on nets and wire mesh. Welding may be performed without using a thread or wire for sewing. Depending on the characteristics of the fabric and the purpose of making the crease, wire may be used instead of thread, stapled, stitched, etc. good. The fold does not need to be connected to the fabric. There are cases such as when you want to switch colors or patterns, when you want to join pieces, or when you want to cut open for design reasons, etc., so there is no restriction on making a single piece of fabric.

[0007]

According to the present invention, there is no need to worry about where to fold because a fold is already formed at the place where the fold should be made and is used as a mark. The landmarks are indicated by physical shapes rather than colors, so that even in an unseen situation, it is easy to find a place to fold. Since it is already folded at the fold and stitched together, it is possible to fold just by sorting the fabric without opposing the direction of the fold. In other words, just shake the whole lightly and release the entangling, it will be folded spontaneously. Since there is no need to press down on the folds with force, there is no need to make tight marks such as with an iron, and no strong force is required. Since the sewing may be performed by hand sewing or a stepping sewing machine, the energy source such as electricity is not necessarily required. No ironing or press is needed to make the folds, and no tools, chemicals, power supplies or heat sources are needed to make the folds. In diapers, towels, handkerchiefs, etc., when folded and sewn together around the stack, a bag-like part is formed. Once the periphery is sewn, it cannot be opened again, so it is difficult to remove dust and dirt from the bag-like portion by washing or the like, and there is a problem in terms of hygiene. On the other hand, according to the present invention, during washing, it spreads freely in water and receives water flow on the back and front surfaces,
It is easy to remove dirt and sanitary. When applied to a towel or a rag, if it is desired to use the back surface during the wiping operation, it is easy to fold the crease according to the present invention in reverse. In particular, if it is wet, it is easy to turn it in the opposite direction immediately beside the crease according to the present invention. Therefore, if the folds are sewn around and the folds are fixed as in a conventional rag, the surfaces that can be used for wiping are limited to the upper surface and the lower surface. However, according to the present invention, eight sides can be used in the case of folding in four. With a rag or the like, a large area can be wiped with a single cleaning. Since it can be creased without the need for heat, creases can be made on heat-sensitive fabrics. Even if the material has low flexibility, such as steel, plastic, or leather, it does not break with the packing at the bent portion, nor does the surface layer crack or peel off. Since it can be handled as one, it can be creased without losing properties such as conductivity, insulation, protection performance, and appearance. It can also be used to make folds on nets and wire mesh. Higher strength can be obtained as compared with the case where creasing is performed by pressing.
