TECHNICAL FIELD OF THE INVENTION
The present invention relates to an extension method for attaching a hair bundle for attachment made of human hair or artificial hair to own hair, and more particularly to an attachment method using a heat-shrinkable tube.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in the field of aesthetic hairdressing, a technique called an extension that attaches a hair bundle for attachment made of human hair or artificial hair to own hair to extend the length of hair or increase the amount of hair. Exists.
[0003]
With respect to such an extension technique, conventional methods as shown in the following (1) to (4) are generally known, but for any of the extension methods, a considerable skill is required for a worker. In addition to this, there is a problem in that it takes considerable time and effort to work, and on the other hand, not only does the user have a heavy burden on the hair and scalp, but also the mounting strength due to the weak binding strength There is also a problem that the hair bundle is easily detached.
(1) Main problems with "How to use glue gun / glue bond" 1) A large load is applied to the hair at the time of attachment and removal 2) Many shampoos tend to soften easily, and the pulling force toward the tip of the hair The hair bundle for attachment is very weak and easily detaches. (2) The main problem with "How to tie with a thread after braiding or four-knitting" 1) It takes time to attach 2) When hair grows, 3) Yarns are easily loosened or entangled. 3) Yarns deteriorate due to water, and are unsanitary. 4) Weak hair pulls to the hair tips. The main problem with the method of tying a knot, braiding and tying it with thread rubber 1) It takes time to install 2) The thread rubber deteriorates with water and is unsanitary 3) Daily life In, hair becomes easy to get entangled, (4) Major problems with “method of crushing metal or hard resin bead chips with pliers” 1) A large load is applied to the hair at the joint 2) Since pliers are used, individual mounting is required However, it is not suitable for continuous long-time work. 3) The attachment tends to be uneven, and if the binding strength is weak, the hair bundle for attachment tends to come off.
In addition, regarding the extension technology, there is a patent application “Method of attaching hair fibers” described below (see Patent Document 1). The purpose of this method is to provide a method of attaching hair fibers that can shorten the attachment time and can be performed by one person. The fiber bundle is crossed, and the hair bundle is wound around the fiber bundle for artificial hair at least one turn at the left and right positions of the intersection (winding step), and the leading end side of the hair bundle and both ends of the fiber bundle for artificial hair A method of attaching hair fibers, which comprises knitting in the vicinity of the intersection (knitting step), separating a part of the fiber bundle for artificial hair, winding the bundle around the knitting part, and heat fusing (heat fusing step). The invention according to claim 2 is characterized in that the self-hair bundle and the hair fiber bundle intersect, and the self-hair bundle is wound around the hair fiber bundle at least one turn at the left and right positions of the intersection ( Winding process), the end of the hair bundle and hair fibers The method for attaching the hair fibers includes knitting the both ends of the hair near the intersection (knitting step) and fixing the knitted portion of the self-hair bundle and the hair fiber bundle by connecting elastic yarn (fixing step). is there.
[0005]
According to the first or second aspect of the present invention, the conventional extension method for knitting two self-hair bundles and both ends of the hair fiber bundle (a total of four bundles) is inherent. It is considered possible to solve the problem (difficulty of mounting alone).
However, in these methods, the winding step and the knitting step are indispensable constituent elements of the present invention. Therefore, as in the above-described conventional extension methods (1) to (4), a considerable amount of work is required for an operator. Not only skill is required, but there are still problems such as a considerable amount of work required.
Further, in the first aspect of the present invention, since the attachment hair bundle is limited to the artificial hair fiber bundle (such as polyethylene), it cannot be used for the hair fiber bundle made of human hair.
Furthermore, in the invention according to claim 2, since the elastic yarn is bound and fixed, the elastic yarn is deteriorated by containing water and unsanitary as in the above-mentioned conventional extension method (3), In everyday life, hair is easily entangled, and a fiber bundle for hair is easily released.
