Description

[Detailed description of the invention] Hair Sera I/Device field of invention The present invention relates to a device used for permanently setting hair, and further relates to a device used for permanently setting hair; Specifically, infrared rays are used as an energy source to control the temperature at which hair is set. related to the equipment used.

Background technology As used in this specification, the term hair permanent set refers to hair that has been chemically treated. The process of changing the structure of the hair thereby breaking down and straightening the covalent bonds of the hair Regarding.

Permanent sets are used to create "permanent" waves, curls, etc. on your hair. used for

The distinction between permanent set processes and combined set processes is that in the latter case leaves the hair damp without any chemical action until the hair is substantially dry This can be done simply on the basis of the point being heated. Add waves or curls to your hair Bonding hair in a formable state occurs as soon as the bonded hair is moistened. Lack of permanence due to lack of curls or waves. excessive circumference Moisture, such as that caused by atmospheric moisture or water washing, is sufficient to avoid damaging the bond set. It is.

In contrast, a permanent set leaves your hair in a smooth, curly state after washing. Unaffected by the presence of water to the extent that it is maintained in a wavy state.

In this technical field, permanent sets are made up of various compositions, typically medium Aqueous solutions of thioglycolates in neutral or alkaline conditions, e.g. This is done by treating the hair with an aqueous solution based on mu-thioglycolate. It is well known that this can be done.

The hair to be set is typically moistened with a thioglycole-1 solution and then shampooed. wound on a permanent or permanent rod. After that, the hair is up to about 3 Leave for 0 minutes, then the hair is treated with a neutral solution, the curl clips are removed, And hair treated this way has almost all of the chemicals used in the treatment removed. It is washed with water to The purpose of using a neutral solution is to prevent thioglycolate from affecting the hair. It should be noted that the reaction must be terminated.

Although the above process has been known for some time, it has since been used extensively for setting compositions. Although it should be noted that the number of There appear to have been relatively few changes made.

One of the disadvantages of this process is the time it takes to set the hair and the amount of time it takes to set the hair. It is the discomfort that accompanies when the person inside has the set set.

For this purpose, the prior art has proposed increasing the reaction rate of the setting composition on the hair by heating. It can be improved. Unfortunately, heating conditions must be very precisely controlled. , the effect of heating on this process is generally too variable and the resulting It has been found that the quality of the prepared sets is usually in an unacceptable condition.

PCT/EF82100173 (W083100606) specification states that human A heat treatment device for hair heating that uses an infrared source to generate heat within the hair. Disclosed. This device is useful for permanently setting hair. is disclosed. However, this device does not allow infrared radiation from sources external to the hair. Care should be taken to generate and apply lines.

Others such as those described in Australian Patent No. 514,434 In the art, infrared hair dryers have been disclosed. This patent and this invention In other technologies known to Ming Applicant, such devices generally uses an infrared source external to the hair along with a blower to avoid drying the hair. child The infrared sources in these devices are clearly used simply as a heat source and are Ambient air is drawn into the infrared source, heated, and blown onto the hair.

U.S. Pat. No. 4,602,143 (Matsuk et al.) discloses that humidified hair is A bonded hair cellar (cohe An apparatus for use in slve hair setting is disclosed.

By controlling and adjusting the duration of action of the infrared source, the hair bond set is The degree of heating can be controlled to quickly dry the hair while forming. Ru.

The applicant of the present invention aims to set hair quickly, reliably, reproducibly and permanently. to set the hair in such a way that it does not get lost in water or high humidity. It is recognized that there remains a need for devices and methods that can.

Disclosure of invention Therefore, one object of the present invention is to provide rapid generation, release and release of energy to the hair. Using infrared light to quickly, reliably, and reproducibly set hair The object of the present invention is to provide a device and a method that can be used permanently. infrared energy Using the Lugi source allows you to set your hair quickly, reliably and reproducibly. extremely important.

The present invention is designed to transmit or absorb infrared rays that wrap around the hair. a hollow winding former, an infrared generating source inside the winding former, and a moving infrared generating source. a biasing means connected to act on said infrared radiation source to cause said infrared radiation to be generated; acting on the biasing means to intermittently operate the external radiation source in a predetermined manner; a control means connected to means for shielding the hair wound on the former to a degree sufficient to maintain it in a moist condition; It is a device that permanently sets hair.

In another aspect, the present invention provides a method for setting hair while the hair is being wound in a curling style. treating the hair with an effective amount of the composition capable of acting on the hair, and increasing the rate of action of said composition. In improving the method of permanently setting hair, the temperature of which increases with increasing temperature, The improvement described above allows sufficient time for the hair to be set by radiation from inside the curling type. The present invention resides in an improvement in a method of permanently setting hair, which includes heating the hair for a period of time.

In still another aspect of the present invention, the infrared light that wraps around the hair can be transmitted through the infrared rays. a hollow former that transmits or absorbs the infrared rays, a source of infrared radiation inside the former; Apply to a sufficient degree to keep the hair moist during the time the source is running. and means for shielding hair wound in a winding form. be.

In yet another aspect, the invention provides 1-4% w/v thioglycolate. A permanent hair set composition comprising:

An advantage of the present invention is that the hair to which the composition is applied is heated from inside the former in which the hair is wound. It uses infrared radiation to minimize heat loss, resulting in time is significantly reduced, and heating of the hair starts and stops within less than 1 second. The reaction rate of the composition on the hair can proceed in a controlled manner. There are many things. Furthermore, because the temperature at which hair changes occur is high, there is less hair breakage. and, therefore, less damage to the hair.

In a typical permanent waving method using the present invention, the structure of the hair is Collapse of bonded bonds is 1/1/2 of the collapse of covalent bonds in the normal node-manent set procedure. It turned out to be 3 or less.

The applicant of the present invention is the applicant of the above-mentioned U.S. Pat. No. 4,602,143 In fact, this patent keeps the hair in a moist form and the hair wraps are placed around the 12 sections. , and the infrared rays inside the hair wrap for a sufficient period of time to substantially dry the hair. Because it concerns a bond set that requires heating by a line source. It is not taught that hair should retain moisture other than the moisture that is normally present in the hair. We note that this is not the case. Therefore, the device disclosed in this specification is One of the features of hair wrapping is that it detects the temperature within the area and controls the temperature within a predetermined range. It also includes a temperature sensor that is now controlled. This temperature sensor is required at least Another reason is that, obviously, once the hair is substantially dry, the infrared sources Be sure to shut off the movement, otherwise the hair will heat up to excessive temperatures It is from. The applicant also stated that the purpose of the invention is to heat hair uniformly and to It states that the purpose is to avoid heat.

In contrast, the present invention allows the reaction with the setting composition to proceed and the hair temperature to approximately Maintaining sufficient moisture in the hair to be able to control temperatures up to 100°C need. Such a requirement is contrary to the teachings of the aforementioned US patents.

The hollow former of the present invention can be constructed from a variety of materials known in the relevant art. can be done. One useful material for constructing a winding form that transmits infrared light is It is silica formed into a vitreous tube. However, silica can be damaged during use. The disadvantage is that they can be damaged or easily damaged. red An alternative to vitreous tubes as external wire absorbing windings is that metals are present in the hair setting composition. It is a metal tube that can withstand many minutes. A particularly useful metal is stainless steel in the order of 0.5 thickness. 316.

The dimensions of the former can be varied within wide limits. However, the length of the winding form is Approximately the length of prior art perming rods and hair curling rods It is a mark.

The width of the former can likewise be varied within wide limits, but the width chosen It is determined by the degree of curl or wave of the hair. Therefore, the width of the former As the value increases, the width of the curl generally increases. The useful width is about 6 + w can be done.

In the present invention, the winding form may be formed into a tubular shape, although other cross-sectional shapes are also possible. It is preferable that One non-limiting example is a hexagon.

In one embodiment where the vitreous tube constitutes the former, in order to obtain sufficient strength, The wall thickness can be set to about 11. However, especially in beauty salons, If the former is likely to be handled roughly, place a wire mesh or guard on the outside of the tube. The tube can be placed over at least one end of the tube. This configuration smells The diameter of the wire selected to construct the wire mesh or guard will not fold during use. Sufficient directness shall be selected to ensure that it will not be damaged or damaged.

The selection of materials constituting the wire should be such that it is inert to the set composition in which the wire will be used. This is important in that it is important. Therefore, if thioglycolate-based If a composition such as It will consist of a number of rules.

In one preferred embodiment, the infrared source uses a voltage in the range of about 4-30 volts. A hot wire, e.g. It is equipped with Kanthal. Infrared rays made from such thin wires The source quickly reaches and cools a predetermined temperature when voltage is applied and removed. be able to. In addition, this high temperature causes the energy transfer to be at the absolute temperature of the wire. It will be proportional to the thousandth power. The heat transfer is from an infrared source with low thermal inertia and Because the heat transfer itself takes place via infrared radiation, rapid response to heating and heat removal is possible. You can get the answer.

A particularly preferred source of infrared radiation is a wire formed from helically wound canthal. It is becoming more and more. Kanthal is a 23-gauge product with a resistivity of 1.58 ohms/ft. It is desirable to have a circular cross section. Approximately 5 ant if canthal is used. A voltage of 6 volts on the pair results in a temperature of approximately 850°C. However, the effect The typical temperature range is approximately 800-1000°C.

Infrared rays are used to clean the former by washing with water to remove the set composition from the former. It is desirable that the line source can be easily removed from the former. infrared source are operatively connected by a pair of wires, so an infrared source is required. Preferably, it can be easily inserted into and removed from the former each time. therefore, If the source of infrared radiation is, for example, a tube, only the tube itself needs to be cleaned. It is. Such a structure further allows the respective infrared generating sources to be removed during use. This is useful in that the hair can be easily wound around each winding pattern. hair Once the are wound onto the formers, an infrared source is inserted into each former. You can do it.

Another infrared number η・j source is an infrared source far from the winding form and an infrared ray source that transmits infrared light into the inside of the winding form. It is equipped with a means by which it can be sent. In such embodiments, infrared The radiation source can typically be an infrared lamp with a power output of about 1 kilowatt. The transmission means can also be an optical fiber.

Waterproof to ensure that sufficient moisture is maintained in the hair while it is being set. A member is placed over the hair that is wound onto the former. The dimensions of the waterproofing member are set selected to ensure that all hair is substantially occluded.

This waterproof material is also impermeable to infrared radiation, which allows infrared rays to pass through the hair and the former. Ensure that no leakage or minimal leakage occurs from the exposed environment. It is desirable that Use materials that reflect infrared rays on surfaces that come into contact with hair It is particularly preferable. The advantage of this structure is that the temperature of the hair and composition increases quickly, Moreover, even more uniform heating is achieved. A useful structure for waterproofing components is metal foil. , especially aluminum foil. This kind of material can be used once the hair is rolled onto the winding pattern. Once applied, it can be easily wrapped around the hair. Also, this material is set Since it comes into contact with the composition for use, it is necessary that it does not substantially react with the composition. This should be kept in mind.

In the case of aluminum, if the composition contains thioglycolate, Aluminum sulfide forms on the surface of the aluminum in contact with the surface becomes unreactive to the composition.

In addition to the waterproofing material, a water-absorbing material is arranged to substantially cover the hair wound on the former. can be placed. This also helps maintain sufficient moisture in the hair. can get.

The transfer of heat from the surface of the former through the hair moves radially outward from the surface of the former. It was found that this was caused by the evaporation and condensation of water. When water condenses, it wicks This action ensures that water is returned to the surface of the former. Once the heating is applied to the entire surface of the hair, Once reached, the water that evaporates leaves the water-absorbing part moisturized with the composition that sets itself. Penetrates into the material. As a result, high-temperature water vapor condenses within the water-absorbing material, creating a wicking effect. More moisture is returned to the hair.

The means for operating the infrared generation source is that the infrared generation source is electrically operated. Equipped with any one type of switch from a wide range of switches known to this technology. You can get it.

The infrared source preferably operates at 6-12 volts for safety and convenience reasons. In the case of hot wires, the voltage is obtained from a transformer operating at mains voltage. 1. However, at 7, the low voltage can be supplied and cut off as required by means of a suitable switch. You can do it.

This transformer is used if the mains voltage fluctuates, for example by 10%, or if an infrared source Maintains a constant current in the infrared source to which the transformer is connected even though the electrical contact resistance varies It is most preferable to have a suitable leakage reactance and saturable iron core type. . In this embodiment, the infrared sources are connected in parallel.

The present invention contemplates that the actual heating time of the hair is generally about 30 seconds to 60 seconds. ing. To achieve such a heating time, infrared radiation is emitted after a predetermined period of time. Control means are used to cut off the supply of current to the source. like this The control means typically interrupts the electrical current to the infrared source after a selected period of time. generally electrically powered and well known in the relevant technical field. Equipped with a timer.

In one particularly preferred embodiment, the control means and the means for operating the infrared radiation source are provided. The stage can be a single device containing a timer with suitable switches.

When the device of the present invention is used in a beauty salon, it generally transmits a plurality of infrared rays. It will be equipped with a hollow winding former, multiple infrared generation sources, and a waterproof member. . The advantage of this structure is that a substantial portion of the hair can be set at the same time. It is.

Enough number of curls and infrared generation to set half of your hair at the same time It is preferable to provide a source and a shrine. Required winding form, infrared source and part The number is normally calculated when the length of the winding form is approximately 8 cm and the diameter is approximately 10 mm. There are approximately 30 hairs per half of the hair on the head.

Therefore, after completing the setting of half the hair, and while the curling form is cooling down. In one embodiment, the infrared source can be removed from the former, allowing the infrared source to be removed from the other side of the head. Advantageously, the second set of formers can be used for winding the hair of the patient. the Then, conveniently insert the infrared source into the second set of winding forms and proceed with hair styling. be able to.

In such embodiments, the control means and the means for operating the infrared source may be It is clear that there is no need to prepare redundantly; The rated output of the selected transformer must be sufficient to operate the external radiation source. No.

One embodiment where a remote infrared lamp is used with optical fibers as an infrared source In some cases, a single infrared lamp is used to supply infrared light to multiple optical fibers. can be used. Therefore, in this embodiment, for each winding form, At least one optical fiber is used.

Although it was mentioned earlier that the curling pattern becomes extremely hot during hair setting, those skilled in the art will know that the Simply ensure that the curler can be safely removed from the hair after sufficient time has elapsed. It will be understood that

The applicant of the present invention has disclosed that the perm silk composition containing about 1-4% thioglycolate is based on the present invention. found to be effective when used with light equipment. This concentration range is Beauty salon composition containing up to 11% thioglycolate, 5-8% thioglycolate significantly lower than household compositions containing

Moreover, prior art permanent procedures typically require a "neutral" solution, typically hydrogen peroxide. However, in the present invention, it is not necessary to use a neutral liquid.

Hair only needs to be washed with water after heat treatment.

Using low concentrations of thioglycollate may reduce hair damage during permanent procedures. This is important because it reduces Moreover, hairdressers at most hair salons wear gloves. Since it is not worn, the incidence of dermatitis is significantly reduced.

From the above description, it can be seen that the prior art process requires at least 20 to 30 minutes. In contrast, the present invention is advantageous in that hair can typically be set within minutes. It is clear that it has one distinct advantage over the prior art.

A further advantage derived from the present invention is that in order to determine the preferred set time, This is because it is customary to set a test section of hair before the section of hair is sent. The test procedure can be performed in a relatively short period of time compared to prior art processes. It is possible. Therefore, the total time for setting is significantly reduced.

What's more, because we use low-1 degree thioglycolate, there is less damage to your hair. and reduce the incidence of dermatitis among hairdressers in beauty salons.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Brief description of the drawing FIG. 1 is an end side view; FIG. 2 is an exploded perspective view of the present invention, and FIG. 3 is a longitudinal view of the infrared source of the present invention. It is a directional cross-sectional view.

FIG. 4 also shows a winding form when the present invention is used in a permanent hair setting procedure. Gradations of temperature measured within the hair curl near the surface of the hair curl and on the outer surface of the hair curl. This shows the f.

Methods for carrying out the invention The device 10 described with reference to FIGS. 1 and 2 is constructed using a waterproof member, which is a clamp J2. The water-absorbing member, which is a tubular piece of Bolistin 1/Nform 14, is sealed. It is provided with a winding form 13 that is surrounded over its entire length.

The former 13 was formed from 316 stainless steel with a wall thickness of 0.5 mm. A tube body 22 is provided. As best understood from FIG. 3, within formers 1-3, An infrared radiation source is provided. This infrared source is located midway along its length in °C. A single helically wound 23 gauge can supported by a mica insulator 20 It is equipped with 17 barrels.

The kanthal 17 is silver soldered into a metal cap 21 at one end.

The cap 21 is secured within the tube body 22 by pleating. In this way, An absolute dielectric constant is established between one end of the canthal 17 and the tube 22. canthal 17 is connected to the plug 15 at the other end. Plug 15 is Teflon It is insulated from the tube body 22 by a plug 16. Plug 15 has suitable dimensions It is designed to accommodate electrical connectors that connect the ends of the Kanthal 17. and a voltage source are electrically connected.

The former 13 is surrounded around its entire length by a tubular piece of polyester foam 14. It is. Polystyrene foam 14 has a length approximately equal to the length of clamp 12. are doing. A slit 19 extending in the longitudinal direction is formed at the top of the form 14. ing. The slit 19 is aligned with the longitudinally extending opening 18 of the clamp 12. I can't stand it. The form 14 is a snug fit within the clamp 12 and a winding form. 13 over its entire length.

In order to securely hold the hair on the former 13, the clamp 12 is fitted as shown in FIG. is usually closed. It has an opening 18 in the clamp 12 the tubular portions extending over their entire length and each separated from the opening 18 and A pair of legs 11 extending downwardly from opposite sides of the part are equidistantly spaced from said opening. This is achieved by In this way, the legs move in the direction shown by the arrow in Figure 1. By applying a force to 11, the opening 18 is enlarged as shown by the arrow, and This makes it possible to remove the winding form 13 via the slit 19.

In use, hair to which an appropriate amount of the perming composition has been added is wound onto the winding form 13. Ru. Thereafter, the clamp 12 moves the leg 11 in the direction shown by the arrow in FIG. The winding form 13 passes through the opening 18 and the slit 19. and is placed in contact with the foam 14. To remove force from the leg 11 As a result, the clamp 12 closes, and the hair wound on the winding form 13 forms the form 14 and and is surrounded by the tubular portion of the clamp 12. This process leaves half of the hair on your head hairless. Iterates until the asset is ready. The plug 15 is then inserted into a suitable socket. and the current is applied for a suitable period of time, typically about 30 seconds to 60 seconds. be done.

The current supplied to the infrared source can be obtained from a high leakage reactance transformer. desirable. Additionally, means to change the voltage, e.g. a simple variable resistor, can be infrared Included to modify the output.

Since the amount of heating time is critical, electrically disconnect power to the infrared source. A timer is used to allow the former to cool once proper heating has been achieved. After that, the former 13 is removed from the clamp 12 and the hair wound around the former is unwound. let go The other half of the hair is then treated as described above. When completed, your hair will be covered in water. The hair is washed and then further conditioned in the usual manner.

Experiments were conducted to demonstrate how hair is rapidly heated. In this experiment, the vol.
