Detailed Description
In addition to the above-described curling shape, a spiral shape is generally given to a bundle of hair, and it has been desired to easily perform an operation of curling the bundle of hair into a spiral shape. The method disclosed in patent document 1 is a method of rolling a bundle of hair into a roll, not a method of rolling a bundle of hair into a spiral shape. Further, with the method disclosed in patent document 1, it is difficult to wind the hair bundle into a spiral shape. The method disclosed in patent document 2 can make a hair bundle into a spiral shape; however, since the diameter of the spiral of the hair bundle is fixed by the diameter of the hair winding portion, the diameter of the spiral cannot be adjusted, which results in low flexibility in setting the hairstyle.
The present invention therefore relates to a hair treatment method and a hair holder which make it possible to eliminate the above-mentioned disadvantages of the prior art.
Hereinafter, a hair treatment method of the present invention will be described based on preferred embodiments of the present invention with reference to the accompanying drawings. The hair treatment method of the present invention is a hair treatment method for curling hair using a hair holder. "curling" refers to imparting a particular shape to a bundle of hair, and as used herein, unless otherwise indicated, "curling" refers to imparting a helical shape to a bundle of hair.
In addition, the hair treatment method of the present invention is mainly applied to hair.
Fig. 1 (a) and (b) show an example of a hair holder used in the hair treatment method of the present invention. The hair holder 1 shown in fig. 1 (a) and (b) includes a cylindrical body 2, and the cylindrical body 2 has an opening 21 at a first end and an opening 22 at a second end. The hair holder 1 is configured such that the hair bundle H can be inserted from the opening portion 21 at the first end to the opening portion 22 at the second end. Specifically, the cylindrical body 2 includes two sheets 23A and 23B elongated in one direction, which serve as a first face sheet 23A and a second face sheet 23B described later, and have a flat shape in which the two sheets 23A and 23B are stacked one on another. The cylindrical body 2 has a pair of side-bonding portions 24, and the first and second face sheets 23A and 23B are bonded to each other at the side-bonding portions 24, and includes a tubular portion 26 between the pair of side-bonding portions 24. Each of the pair of side bonding portions 24 is formed by bonding side edge portions of the two sheets 23A and 23B to each other along an extending direction in which the sheets 23A and 23B extend. The tubular portion 26 has a space in the longitudinal direction X between the opening portion 21 at the first end and the opening portion 22 at the second end, in which the hair bundle H can be inserted. In the present embodiment, the side joint portions 24 are formed by sewing using a sewing thread.
The tubular body 2 of the present embodiment has a longitudinal direction X and a width direction Y orthogonal to the longitudinal direction X. The longitudinal direction X of the cylindrical body 2 is the same as the extending direction of the tubular portion 26 and corresponds to the inserting direction of the hair bundle H.
As shown in the present embodiment, both side edge portions of the cylindrical body 2 extending in the longitudinal direction X are parallel to each other; however, the both side edge portions are not necessarily parallel to each other. In this case, both side edge portions preferably extend gradually outward in the width direction Y from the opening portion 21 at the first end to the opening portion 22 at the second end. In other words, it is preferable that the cylindrical body 2 has a shape widening toward the opening portion 22 of the second end in plan view.
The cylindrical body 2 is configured to be rollable. The configuration to be rollable means that the cylindrical body 2 can be rolled into a roll shape as shown in fig. 2. This structure is preferably a structure in which the cylindrical body 2 is automatically rolled up, but may be a structure in which the cylindrical body 2 is manually rolled up. One example of the automatic rolling configuration is a configuration in which the cylindrical body 2 is rolled in a roll shape in its natural state, and after the cylindrical body 2 is stretched and the hair bundle H is inserted therein, the cylindrical body 2 is rolled together with the hair bundle H when released from the stretched state. Such a structure may be realized in such a manner that one or both of the first sheet 23A and the second sheet 23B is composed of a shape memory sheet that preliminarily maintains the rolled state of the hair holder 1. For example, the shape memory sheet can be formed by bonding films having different heat shrinkages or films having different tensions together. Further, when the sheets 23A and 23B constituting the cylindrical body 2 are heated, the cylindrical body 2 can also be restored to the original roll shape it holds. As used herein, "in its natural state" means a state in which the hair holding device to which no external force is applied is placed horizontally in an environment having a temperature of 20 ℃ and a humidity of 40%.
The sheet located on the inner side when the cylindrical body 2 is rolled up is also referred to as a first sheet 23A, and the sheet located on the outer side when the cylindrical body 2 is rolled up is also referred to as a second sheet 23B.
After the hair bundle is inserted into the hair holder from the opening at the first end of the cylindrical body to the opening at the second end thereof, the cylindrical body is rolled up together with the hair bundle, and the hair holder is formed into a roll shape. In the following description, the cylinder rolled up in a roll shape will also be referred to as a hair bundle holder. The hair bundle holding body has a spiral cross-sectional shape in a radial direction orthogonal to a central axis direction of the roll. In the hair bundle holder, the opening of the second end is located on the center side of the wound roll. The center is positioned on the central shaft of the rolling hair bundle holding body. In the following description, the center of the hair bundle holder will also be referred to simply as "center".
The hair bundle holder 3 has an outer peripheral portion 31 and a portion 33 closer to the center than the outer peripheral portion 31. The portion 33 near the center will also be referred to as a "center-side portion 33". The outer peripheral portion 31 is a wound portion that is farthest from the central axis in the cylindrical body 2 in a wound state, that is, a state in which it is wound into a roll, and is a portion having the largest winding diameter in the cylindrical body 2. The center side portion 33 is a wound portion relatively close to the center axis with respect to the outer peripheral portion 31, and has a smaller winding diameter than the outer peripheral portion 31. The number of windings of the winding portion constituting the center side portion 33 may be not more than one turn, equal to one turn, or may be two or more turns. The center side portion 33 of the hair bundle holder 3 shown in fig. 2 is constituted by a wound portion formed by three turns. Note that, in the present embodiment, the outer peripheral portion 31 is a wound portion of the cylindrical body 2, and does not include the extension 4.
The hair treatment method of the present invention includes a step of forming a hair bundle holding body, a step of deforming a cylindrical body into a spiral shape, and a step of performing a curling treatment on a hair bundle. In the following description, the step of forming the hair bundle holder will also be referred to as a rolling step, the step of deforming the cylindrical body into a spiral shape will also be referred to as a deforming step, and the step of performing a curling process of the hair bundle will also be referred to as a curling process step.
A preferred embodiment of the hair treatment method of the present invention will be described taking as an example a case where the hair treatment method is performed using the hair holder shown in (a) and (b) in fig. 1. Fig. 3 (a), (b), (c), and (d) illustrate the hair treatment method of the present embodiment.
In the present embodiment, the insertion step of inserting the hair bundle H into the cylindrical body 2 is performed at a stage prior to the rolling step. In this step, as shown in fig. 3 (a), the hair bundle H is inserted between the two sheets 23A and 23B constituting the tubular body 2 from the opening 21 at the first end toward the opening 22 at the second end of the tubular body 2. Therefore, in the tubular body 2, the root side of the hair bundle H is located on the opening 21 side of the first end, and the tip side of the hair bundle H is located on the opening 22 side of the second end. The operation of inserting the hair bundle H may be performed using the hand of the operator at the insertion step, or may be performed using an elongated hair insertion tool for inserting the hair bundle H into the cylindrical body 2. An example of the hair insertion tool is a hair insertion tool having a locking portion capable of locking a hair bundle H and an elongated insertion tool body having a predetermined length. More specifically, in the hair insertion tool, the insertion tool body is formed in an elongated plate shape, and the end portion thereof has a tapered shape so as to be easily inserted into the opening of the first end of the cylindrical body 2. Preferably, the insertion tool body is formed of a hard synthetic resin sheet or the like. The locking portion is provided at one end of the insertion tool body, and is formed in a ring shape longer than its width, through which the hair bundle can be inserted and locked.
In this step, it is sufficient that the hair bundle can be inserted into the cylinder, and the hair bundle does not need to penetrate the tubular portion 26. In other words, the front end of the hair bundle need not protrude from the opening of the second end of the barrel.
In the rolling step, the tubular body 2 is rolled together with the hair bundle inserted into the tubular body, thereby forming a hair bundle holding body. In this rolling step, as shown in fig. 3 (b), the tubular body 2 is rolled from the opening 22 at the second end to the opening 21 at the first end along the longitudinal direction X. That is, the cylindrical body 2 is rolled up so that the opening 22 of the second end is positioned on the center side of the rolled hair holding body. Therefore, the tip side of the hair bundle H is positioned on the center side of the hair bundle holder, and the root side thereof is positioned on the outer peripheral side of the hair bundle holder. In this step, the hair bundle holder may be formed of a structure in which the aforementioned tubular body 2 is automatically rolled up, or may be formed of a structure in which the aforementioned tubular body 2 is manually rolled up. The hair bundle holding body may also be formed by winding up the cylindrical body 2 using an automatic winding-up configuration and then further manually performing a winding-up operation or an unwinding operation.
In the deforming step, as shown in fig. 3 (c), the portion 33 of the hair bundle holder 3 located on the center side is pulled out toward the lateral side of the hair bundle holder 3, and the cylindrical body 2 is deformed into a spiral shape.
The "lateral side of the hair bundle holder" means the outer side of the hair bundle holder 3 in the width direction Y of the tubular body 2, and the lateral side extends in the direction of the central axis of the hair bundle holder 3. In the deforming step, the center-side portion is pulled out to the lateral side of the hair bundle holder, and the center-side portion is moved from the outer peripheral portion of the hair bundle holder to the lateral side, whereby the cylindrical body 2 is deformed into a spiral shape. The center side portion 33 is pulled out by, for example, grasping either the tubular portion 26 or the side edge portion in the vicinity of the opening portion 22 at the second end in the longitudinal direction X. Note that the hair holder 1 of the present embodiment has a later-described wind-up tab 8 on the opening portion 22 side of the second end in the length direction X, and the center-side portion can also be pulled out by gripping the wind-up tab 8.
In the deforming step of the present embodiment, as shown in (c) of fig. 3, the center side portion 33 of the hair bundle holder is constituted by the wound portions formed by winding the center side portion of the cylindrical body 2 three times, and these wound portions are pulled out toward the lateral side of the hair bundle holder 3. The wound portions of the center side portion 33 thus drawn are referred to as a first wound portion r1, a second wound portion r2, and a third wound portion r3, respectively, in descending order of distance from the outer peripheral portion 31. The cylindrical body 2 that has been deformed into a spiral shape has a shape in which the leading end becomes narrower as the distance from the outer peripheral portion 31 increases. That is, its length in the radial direction decreases from the third winding portion r3 to the first winding portion r 1.
In the hair treatment method of the present embodiment, a winding-up operation or an unwinding operation described later is performed in the deforming step. However, this step may be performed to the next wrapping process step without performing the above-described operation.
In the curling process step, a curling process of the bundle of hair is performed while maintaining the cylindrical body in a spiral shape. In this step, a fixing member 5 capable of fixing the cylindrical body in a spiral shape may be used. The fixing member 5 will be described later. When the barrel maintains the spiral shape, the hair bundle held in the barrel also maintains the spiral shape. In this state, the curling treatment of the hair is performed. The curling treatment is a treatment of imparting a spiral shape to a hair bundle, and examples thereof include a treatment of allowing a spiral-shaped cylindrical body to remain for a predetermined period of time, a treatment of heating the cylindrical body, and a redox treatment performed by applying a permanent wave agent to the hair bundle from the outside of the cylindrical body.
As shown in fig. 4 (a), the curling process step is completed by removing the bundle of hair from the cylindrical body. For example, a spiral shape as shown in fig. 4 (b) is imparted to the hair bundle removed from the barrel. After the curling treatment step, the curled hair bundle may be post-treated, if necessary. As the post-processing, drying using a drying device (e.g., a dryer), application of a hair treatment agent, and other processing may be performed individually or in a combination of two or more. Examples of hair treatment agents that can be used in post-treatment include hair care agents, hair pre-care agents, styling agents, hair tonics, and the like.
According to the hair treatment method of the present embodiment, since the hair bundle can be formed into the spiral shape by pulling out the center side portion of the hair bundle holder toward the lateral side of the hair bundle holder, the operation of winding the hair bundle into the spiral shape is simple. Since the operation is simple, the finishing quality of curling is not easily affected by the skill of the operator, and the hair treatment time can be shortened.
According to the hair treatment method of the present embodiment, since the cylindrical body is rolled together with the hair bundle inserted therein and deformed into a spiral shape, the diameter of the spiral of the hair bundle and the length of a single turn of the spiral in the central axis direction can be adjusted. Specifically, the diameter of the spiral of the hair bundle can be adjusted by the operation of winding up or unwinding the cylindrical body in the winding-up step. The length of a single turn of the spiral in the central axis direction is the length of the wound portion corresponding to the single turn of the spiral in the central axis direction, and may be adjusted according to the degree to which the center side portion of the hair bundle holder is pulled out, that is, the degree to which the center side portion is offset from the outer peripheral portion side portion. The length of a single turn of the helix in the direction of the central axis can be adjusted for each turn of the helix. Since the above-described adjustment is possible, the hair treatment method of the present embodiment provides a high degree of flexibility in the helical shape that can be imparted to the hair bundle, and makes it easy to curl the hair bundle into a desired form. In the hair holder according to the present embodiment, the hair bundle is formed into a spiral shape in a state where the tension is applied to the hair bundle by the above-described operation, and therefore, a clean spiral shape can be imparted to the hair bundle.
Compared with a method of curling a hair bundle by winding the hair bundle around a heated hair wound part in the case of a hair iron, the hair treatment method of the present embodiment is safe and the treatment of the hair holder is easy.
Further, according to the hair treatment method of the present embodiment, since the hair holder is deformed into the spiral shape, the overlapping portion between the outer peripheral portion side portion and the center side portion of the hair bundle holder is small as compared with the case where the hair holder is rolled into the roll shape. Therefore, according to the hair treatment method of the present embodiment, when the bundle of hair in the cylindrical body is to be dried, the drying time can be shortened to be shorter than that in the case of the hair holder wound in a roll shape. Further, in the case where the treatment of applying the permanent wave agent to the hair bundle from the outside of the cylindrical body is performed as the curling treatment, the hair treatment method of the present embodiment can apply the permanent wave agent to the hair bundle more uniformly than the case of the hair holder wound in a roll shape. Thus, the hair bundle can be arranged in a neat spiral shape.
In the hair treatment method of the present embodiment, in the deforming step, the operation of winding up or unwinding is performed for the portion pulled out to the lateral side of the hair bundle holding body. In the following description, the winding-up operation or the unwinding operation will also be referred to as a winding adjustment operation. With this configuration, the curl diameter of the spiral shape of the hair bundle can be made substantially uniform. In the present embodiment, after the tubular body 2 is deformed into a spiral shape in the deforming step shown in (c) in fig. 3, the tubular body 2 is unwound as shown in (d) in fig. 3 to reduce the difference in the winding diameters of the respective wound portions, i.e., the first wound portion r1, the second wound portion r2, the third wound portion r3 and the outer circumferential portion 31. By such a simple winding adjustment operation, the winding diameter of the wound portion of the hair bundle H in the tubular body 2 can be made substantially uniform, and the hair bundle H can be arranged in a more tidy spiral shape.
The winding adjustment operation may be performed by grasping, for example, a side edge portion of a winding portion farthest from the outer peripheral portion 31, which is a portion located on the center side of the hair bundle holder. This will be explained by taking the present embodiment as an example. If first winding portion r1 is unwound by gripping a side edge portion of first winding portion r1, second winding portion r2 and third winding portion r3 are unwound accordingly. Therefore, the roll diameters of the first to third wound portions r1, r2, and r3 can be made closer to the roll diameter of the outer peripheral portion 31. Alternatively, the winding adjustment operation may be performed by grasping the side edge portion of each of the wound portions of the center side portion, and in this case, the winding diameter of each of the wound portions can be finely adjusted. Note that, as described above, the hair holder 1 of the present embodiment has the wind-up tab 8, which will be described later, and the winding adjustment operation can also be performed by gripping the wind-up tab 8.
In the deforming step, the length of the center side portion 33 pulled out to the lateral side of the hair bundle holder 3 is not limited to a specific length. From the viewpoint of more reliably imparting the spiral shape to the hair bundle, the spiral height H10 of the cylindrical body 2 that has been deformed into the spiral shape is preferably not less than 1.2 times, more preferably not less than 1.3 times, preferably not more than 1.7 times, more preferably not more than 1.5 times, and preferably 1.2 to 1.7 times, and more preferably 1.3 to 1.5 times, of the width W2 of the cylindrical body 2 before the rolling, and more preferably 1.3 to 1.5 times, of the width W2.
The width W2 (see (b) in fig. 1) of the cylindrical body 2 is the minimum width of the cylindrical body 2 in the width direction Y in plan view before the cylindrical body 2 is rolled up. The spiral height H10 (see (c) in fig. 3) of the cylindrical body 2 is the maximum height of the spiral-shaped cylindrical body 2 in a state where the central axis of the spiral-shaped cylindrical body 2 extends parallel to the vertical direction. Note that the width W2 and the helical height H10 of cartridge 2 are widths and heights that do not include the extensions and take-up tabs described below.
According to the hair treatment method of the present invention, the hair bundle may be partially curled, or the hair bundle may be completely curled. In the case where the hair bundle portion is curled, a portion between the root and the tip of the hair bundle arranged in the cylindrical body, that is, for example, a root side portion, a tip side portion including the tip, or an intermediate portion between the root side portion and the tip side portion may be curled.
In the hair treatment method of the present invention, it is preferable to curl the hair bundle in a state in which moisture is applied to the hair bundle in advance, from the viewpoint of easier imparting of the spiral shape to the hair bundle. In this case, the moisture is preferably applied to the hair strands at a stage prior to the rolling step, or more preferably prior to the inserting step. Further, although water may be applied to the hair strands, a water-containing styling agent may also be applied. Commonly used commercially available styling agents can be used as the styling agent. Examples of components other than water contained in the styling agent include: silicone oil, alcohols having 1 to 4 carbon atoms (ethanol, propanol, isopropanol, tert-butanol and 1, 3-butenol), cationic polymers, various kinds of oil agents, and the like. Oils are used to improve the collectability of the hair after drying. Examples of the oil agent include: hydrocarbons such as squalene, squalane, liquid isoalkanes, light liquid isoalkanes, heavy liquid isoalkanes, alpha-olefin oligomers, liquid paraffins and cycloalkanes; glycerides, such as castor oil, cocoa butter, mink oil, avocado oil and olive oil; waxes such as spermaceti, lanolin, beeswax, microcrystalline wax, gluten wax and carnauba wax; esters such as octyl myristate, isopropyl palmitate, hexyl laurate, cetyl lactate, propylene glycol monostearate, oleyl oleate, cetyl 2-ethylhexanoate, isononyl isononanoate and tridecyl isononanoate; higher fatty acids such as capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, pecan acid, oleic acid, palm oil fatty acid, isostearic acid and isopalmitic acid; higher alcohols such as myristyl alcohol, cetyl alcohol, oleyl alcohol, stearyl alcohol, isostearyl alcohol, benzyl alcohol, 2-octyldodecyl alcohol, and cetyl alcohol; and isostearyl glyceryl ether, polyoxypropylene butyl ether, and the like. The method of applying moisture to the hair bundle is not limited to a specific method, and examples thereof include a method of spraying water or a styling agent onto the hair bundle using a sprayer or the like and a method of pouring running water onto the hair bundle using a shower or the like. Furthermore, it is also possible to wash the hair before performing the hair treatment method, and to perform the curling in a state where the hair is not dried or semi-dried.
From the viewpoint of more reliably imparting the spiral shape to the hair bundle, it is preferable that the hair bundle held in the spiral cylindrical body is subjected to permanent wave treatment in the rolling-up step. The permanent wave treatment is a treatment for curling by performing a redox treatment, and is generally performed using a permanent wave agent. The known permanent waving agent can be used as a permanent waving agent. For example, a two-component reagent consisting of a first reagent containing a reducing agent and a second reagent containing an oxidizing agent may be used. Here, the reducing agent cleaves the disulfide bonds of keratin constituting the hair, and examples thereof include thioglycolic acid and derivatives thereof, thiolactic acid and derivatives thereof, cystine and derivatives thereof, and salts of these agents, and the like. Oxidizing agents cleave disulfide bonds of keratin in recombinant hair, examples of which include potassium bromate, sodium perborate, and hydrogen peroxide.
In the curling process step, a permanent waving agent may be injected into the barrel through, for example, a slit (to be described later).
The hair holder 1 of the present embodiment has a plurality of slits 25, and these slits 25 are arranged intermittently in the second surface piece 23B along the longitudinal direction X. Each slit 25 extends in the width direction Y. In this embodiment, the slit penetrates the second face sheet in a thickness direction of the second face sheet. Even if the hair holder does not necessarily need to have slits, the hair holder preferably has a plurality of slits arranged in series from the viewpoint of smoothly rolling up the cylindrical body 2. It is sufficient to form slits in one or the other of the surfaces constituting the cylindrical body 2, but slits may be formed in both surfaces, but it is preferable to form slits in the second surface sheet 23B located outside when the cylindrical body 2 is rolled up. Further, as shown in fig. 6, each slit may have rounded portions at both ends thereof. For example, both ends of each slit shown in fig. 6 may be rounded by punching.
The hair holder 1 of the present embodiment has the extending portion 4 near the end of the opening 21 at the first end of the tubular body 2, and the extending portion 4 is constituted by the first surface piece 23A extending outward in the longitudinal direction X from the tubular body 2. The extension 4 is integrally formed with the first face sheet 23A. Although the hair holder does not necessarily need to have an extension portion near the end of the opening portion of the first end, the hair holder preferably has an extension portion from the viewpoint of ease of inserting the hair bundle into the cylindrical body.
Further, it is preferable that the hair holder has an extension portion because, as described later, if the hair holder 1 has a fixing member 5 capable of holding the cylindrical body in a spiral shape, at least one (but not all) of a plurality of members constituting the fixing member 5 may be provided in the extension portion.
From the viewpoint of ease of performing the curling operation, it is preferable that the cylindrical body of the hair holding tool is held in a spiral shape by a fixing means that holds the cylindrical body in a spiral shape in the curling processing step. Examples of the fixing means include a hair clip that fixes the cylindrical body by pinching the cylindrical body from the inside of the space where the center shaft is located and the outer peripheral portion side of the spirally shaped cylindrical body, and a hair band member that fixes the cylindrical body by winding around the outer peripheral portion or the like of the cylindrical body in a spiral shape, and the like.
As described above, the fixing means for holding the cylindrical body 2 in the spiral state can be separated from the hair holder. However, from the viewpoint of improving the convenience of the curling operation, it is preferable that the hair holding tool has a fixing means. For example, as shown in (a) and (b) of fig. 1, the hair holder 1 of the present embodiment has a fixing member 5 that holds the cylindrical body 2 in a spiral shape, and the fixing member 5 has a first member 5a and a second member 5b that are detachably joined together. The first member 5a and the second member 5b are disposed at positions such that the first member 5a is partially opposed to the second member 5b in the spirally shaped cylindrical body 2. For example, in the hair holder 1 of the present embodiment, the first member 5a is provided on the outer surface of the first sheet 23A, and the second member 5B is provided on the outer surface of the second sheet 23B. "outer surface" refers to the surface opposite the surface that forms the space into which the hair strands can be inserted. When the cylindrical body 2 is deformed into a spiral shape, the outer surface of the first face sheet 23A and the outer surface of the second face sheet 23B are partially opposed, and the first member 5a and the second member 5B positioned in the opposed portions may be bonded together. In the present embodiment, the first member 5a is located in a portion on the outer surface of the first panel 23A, which constitutes the outer peripheral portion 31 of the cylindrical body 2 when the cylindrical body 2 is deformed into a spiral shape, and the second member 5B is located in a wound portion on the outer surface of the second panel 23B, which is adjacent to the outer peripheral portion 31. The wound portion adjacent to the outer peripheral portion 31 is a wound portion included in a portion of the helical cylindrical body 2, which is pulled out toward the lateral side of the hair bundle holder 3, and is closest to the outer peripheral portion 31. That is, the winding portion is the third winding portion r3 of the present embodiment. In the present embodiment, as shown in fig. 5, the first member 5a is joined to the second member 5b in the overlapping portion between the third winding portion r3 and the outer peripheral portion 31. When the first member 5a and the second member 5b provided at the above-described positions are joined together, the cylindrical body 2 can maintain a spiral shape.
Any fastener may be suitably used as the fixing member 5. The fastener is a joining member, or a male-female member. The coupling member and the male and female members are constituted by a plurality of members that can be detachably coupled to each other. Examples of the bonding member include an adherend-selective pressure-sensitive adhesive tape, a magnet, and the like. Examples of male and female members include hook eyes, mechanical hook and loop fasteners, and the like.
An adherend-selective pressure-sensitive adhesive tape is a pressure-sensitive adhesive tape that adheres only to a specific substance and does not substantially adhere to any other substance. "substantially non-adhesive" includes not only the case where the adherend selective pressure-sensitive adhesive tape does not produce an adhesive state with any substance other than the specific substance but also the following cases: even if the adherend-selective pressure-sensitive adhesive tape forms an adhesive state with a substance other than the specific substance, if a slight relative movement occurs between the substance and the adherend, the adhesive state disappears soon. Such an adherend-selective pressure-sensitive adhesive tape includes an adhesive tape base material and a self-adhesive applied to the adhesive tape base material, and the self-adhesive adheres only to the same kind of substance and does not substantially adhere to other substances. That is, the self-adhesive has adhesion only to the self-adhesive itself.
As an example of the adherend-selective pressure-sensitive adhesive tape having the above-described configuration, a pressure-sensitive adhesive tape including a self-adhesive and a tape base material disclosed in japanese patent laid-open No. 2007-167192 can be used.
As shown in fig. 1 (a) and (b), the hair holder 1 of the present embodiment has the winding-up tabs 8 in both side edge portions of the cylindrical body 2, respectively, the winding-up tabs 8 being located in the vicinity of the opening portion 22 side of the second end. As shown in fig. 1 (b), the wind-up tabs 8 extend outward in the width direction Y from the cylinder 2 and are formed integrally with the first panel 23A, and each has a semicircular shape in plan view. Since the hair holder has the rolling-up tab, the cylindrical body can be rolled up easily by gripping the rolling-up tab by hand and if necessary, tightly. Furthermore, in the hair bundle holder, the central side portion can be pulled out to the lateral side by gripping the wind-up tabs, thereby improving the ease of handling of the deformation step. The forming method, shape, size, thickness, arrangement, etc. of the wrap-up tab 8 may be set as appropriate.
According to the hair holder of the above embodiment, the hair bundle holder 3 can be formed by winding the tubular body 2. However, from the viewpoint of ease of rolling the hair bundle into a spiral, it is preferable that, in the hair retainer, the cylindrical body is rolled up in a spiral shape when it is in a natural state. In the following description, this hair holder will also be referred to as a helical hair holder 1 a. The spiral hair holder may have a configuration similar to the configuration of the hair holder described above, except that the cylindrical body has a spiral shape in its natural state. In the spiral hair holder 1a, the cylindrical body 2a is wound in a spiral in its natural state as shown in fig. 7, and such a spiral shape can be maintained without including the aforementioned fixing member in the spiral hair holder. The spiral hair holder 1a is configured in such a manner that, after the cylindrical body 2a is stretched, the cylindrical body 2a is automatically wound up in a spiral shape when released from the stretched state. The cylindrical body 2a can be obtained by using a shape memory sheet for one or both of the two sheets constituting the cylindrical body 2a and keeping the shape memory sheet in a state of being wound up in a spiral shape. In order to keep the shape memory sheet in a rolled-up state, for example, the shape memory sheet is rolled up in a spiral and heated in the rolled-up state. A shape-memory sheet having the same configuration as described above can be used as the shape-memory sheet, except that it returns to its spiral shape upon heating.
From the viewpoint of more reliably imparting the spiral shape to the hair bundle, in the spiral hair holder, the spiral height of the cylinder in its natural state is preferably not less than 1.2 times, and more preferably not less than 1.3 times, preferably not more than 1.7 times, and more preferably not more than 1.5 times, of the width of the cylinder before being rolled, and preferably 1.2 to 1.7 times, and more preferably 1.3 to 1.5 times, of the width of the cylinder before being rolled. The meaning of the helix height is as described above.
From the viewpoint of facilitating the rolling of the cylindrical body into a spiral shape, it is preferable that the spiral hair holder has a plurality of slits extending in the width direction and intermittently arranged in the length direction of the cylindrical body. From the same viewpoint, it is preferable to form slits in the second surface sheet.
A hair treatment method using a spiral hair holder 1a includes an inserting step, a rolling step, and a curling step. In the insertion step, the hair bundle is inserted into the cylindrical body 2a in a stretched state. In the rolling step, the cylindrical body 2a is rolled up into a spiral together with the hair bundle inserted into the cylindrical body 2 a. The cylindrical body 2a is automatically wound up as described above. In the curling process step, a hair bundle is subjected to curling process. The present hair treatment method may have a configuration similar to that of the above-described hair treatment method shown in fig. 3, except that the cylindrical body 2a is rolled up into a spiral in the rolling-up step, and the present hair treatment method does not include the above-described deforming step.
Materials for forming the various parts of the hair holder and the helical hair holder will now be described.
Examples of the material for forming the sheet constituting the cylindrical body include nonwoven fabric (polyethylene nonwoven fabric, polyethylene terephthalate nonwoven fabric, etc.), woven fabric, mesh sheet, porous or non-porous resin film (polyethylene film, polyethylene terephthalate film, etc.), paper, sheet of polymer material, sheet of rubber, composite of these materials, and the like.

Preferably, the sheet constituting the cylindrical body is treated to improve the diffusibility of the hair treatment agent (e.g., permanent wave agent). Examples of such treatments include, but are not limited to, embossing, calendering, resin film forming, and the like. For example, embossing may improve diffusivity by forming protrusions that are continuously aligned in the length direction of the sheet so as to allow the hair treatment agent to flow along the protrusions. By adjusting the density of the sheet constituting the cylindrical body, the diffusion of the hair treatment agent can be improved by calendering. The resin film forming can improve the diffusibility of the hair treatment agent by forming a resin film having low liquid absorbency partially or entirely on the sheet constituting the cylindrical body to reduce the total liquid absorption amount of the sheet.
