Method
According to first aspect of the present invention, we provide the method for measuring the friction that is generated by a branch of hair fiber, comprise friction means is provided, and friction means is pulled through this Shu Maofa, generated the friction noise signal thus and caught the friction noise signal by sensor noise.Usually the noise signal of being caught is changed into displayable form.Use display unit to show the signal that is transformed then.Such parts can include but not limited to be selected from following one group display screen: computer screen, cathode ray tube device and liquid crystal indicator.
In the present invention, mensuration is by the friction of a branch of piliation.Hair can be any mammal, the hair of preferred people, Canis familiaris L., horse or cat, more preferably people's hair.The hair bundle can be sample of hair or wig, but is preferably the hair in consumer's head growth.
In the methods of the invention, need both use friction means also to use sensor noise.Friction means is pulled through the hair bundle, makes its contact and by every hair surface.This has generated friction between friction means and hair.We find that the friction noise of generation depends on the friction level between friction means and the hair surface.
Friction means is generally formed by hard material, preferred polymer materials.For example, friction means can form with high density polyethylene (HDPE).
Friction means preferably be have a plurality of, preferred at least 3, the more preferably form of the carding element of at least 4 teeth.Usually in comb mode commonly used carding element is pulled through the hair bundle.This can finish by the tested object that will estimate its hair or by another tested object.
The friction noise signal that generates is caught with friction noise pick off, preferred microphone.Microphone can for example be that standard electronic microphone or noise are eliminated microphone.
In case caught friction noise, promptly can show and analyze friction noise by any suitable mode.Visual display unit (VDU) preferably also is provided, and will changes into signal, afterwards signal is transferred on the visual display unit (VDU) and demonstration by the friction noise of sensor sensing.For example, it can show with the form of sound amplitude to the trace of time.This transforms available known parts and finishes.
Signal shows preferably instantaneous basically carrying out, and promptly friction means is pulled through the hair bundle and the demonstration of the friction signal that generates and the action that friction means is pulled through the hair bundle are carried out simultaneously.
In the methods of the invention, shown friction noise signal can make friction means only pass hair Shu Yici and obtain.Also friction means can be pulled through twice in hair or more times obtains.Can be with result's accumulative total or average.
Though the inventive method provided herein is suitable for carrying out separately, it also can be united with other method of assessing hair infringement and carries out.Can unite other method of carrying out with the inventive method can include but not limited to: by the self-intuition evaluation of experimenter's enforcement, by experimenter or other people vision or the physical evaluation that consultant implements of for example improving looks, use the evaluation of other device acquisition of measuring the hair infringement, the chemistry evaluation of hair, for example, estimate amount that rupture in experimenter's hair and the disulfide bond cysteine that does not rupture, and combination.Being applicable to that hair of the present invention infringement assay method includes but not limited to adopt estimates degree of roughness, and infers the method for the device of infringement by measuring owing to apply the friction level that some conditions generate to hair.For example, the smoothness of combing is commonly used to a kind of balancing method as slickness.In a kind of combing test, use comb to be pulled through a branch of hair fiber and comb the logical required power of hair and estimate friction, coarse and damage.
Device
Aspect second, the present invention also provides the device of the method that is applicable to first aspect.This device comprises carding element and the friction noise pick off with a plurality of teeth.Preferably will install global design and become to be suitable for the form used with hands.It often extends.Carding element generally places an end of the device of extension.
Device preferably is at least two discerptible parts.In this case, first part comprises carding element, second part comprises the shell that the friction noise pick off is housed, and if necessary, be used for by the friction noise sensor to signal change into the parts that can be transferred to the signal on the visual display unit (VDU).
Sensor noise should be close to obtain the optimum sensitivity to the friction noise that generates with carding element.Yet generally speaking, it should not contact with carding element.Therefore, generally having protector between sensor noise and carding element contacts to prevent two parts.Protector can be made by any protectiveness material, and role is to prevent that the comb parts from contacting with sensor noise, makes that simultaneously contacting the friction noise that generates with hair by carding element passes through.
In order to detect friction noise signal by carding element and piliation, we find about 50 hertz to about 5,000 hertz detection frequency range be preferred.
Accompanying drawing 1 to 4 has shown apparatus of the present invention for example.What device 1 showed is the shape of extending.It has carding element 3 at free end 2, and carding element 3 has tooth 4.Comb can form with high density polyethylene (HDPE).Device 1 can be before using, during and storage afterwards, for example on the magnetic support, preserve.
Tooth passes through sample of hair and generates friction noise, and friction noise detects by microphone 5.It between microphone 5 and comb guard block 6 with the foamed materials formation of foam, preferred free location.Microphone 5 is connected with circuit board 7, and circuit board 7 changes into the signal of telecommunication with the friction noise that generates, and the signal of telecommunication is delivered to the parts (not shown) that is used for signal is changed into visual display along cable 8.For the ease of using, can set cable 8 for retractile form.
Device 1 assembling should make microphone 5 detection signal always.Can come change-over switch 9 by pressing switch top cover 10, should take place with the demonstration and/or the record of indicating the friction noise signal.Record is by " ON/OFF " light emitting diode 11 indication, and its signal can be seen from the outside by light pipe 12.
Microphone and circuit board are included in the protecting sheathing 13, and shell 13 is connected with comb 3 removably.Can for example take off comb 3 by turning.She Ji advantage is can take off that comb cleans or replace with new comb like this.
Though known relevant between friction by the combing piliation and hair infringement, we find that when using friction noise to estimate friction level according to the present invention, this is not unique key factor.Friction noise generates the accurate indication that has provided friction level, but we find that the feature of definite hair of being tested is to estimate whether the friction that is increased is because very important due to infringement and/or coarse hair surface or the other factors (for example hair waving).We find that this makes it possible to accurately analyze any particular hair sample (for example hair of consumer tests object), to determine the infringement level of this particular hair sample.In the present invention, can be by observe different frictions and the infringement level in the single sample when carding element change of amplitude when the sample.
System
Therefore, according to the 3rd aspect of the present invention, we provide a kind of system that is used for the infringement level of assessing hair test sample book, comprising:
The hair kind H of definition predetermined number,
The representative standard trace T of each hair kind H and friction noise signal is associated, and this standard trace T generates when the master sample of giving this hair kind apoplexy due to endogenous wind is implemented said method,
Specify a predetermined kind Ht for described test sample of hair,
On described sample of hair, implement said method,
The friction noise signal that on screen, is generated with the trace visual display,
With the trace Tt of described sample with and the relevant criterion trace T of kind Ht compare.
In this system, need the predetermined hair kind of definition some.These kinds are to define by its trend that generates friction.For example, in a system, can pre-defined 3 kinds: high friction, medium friction and low friction.
Specify a kind of in the middle of these predetermined kind for dissimilar hairs according to correlative factor then.These factors can be selected from ethnic origin (if for example hair is European, Aisan or African); Crimpiness (hair is straight, wave or curling); Whether hair carried out processing (hair-waving, bleaching or hair dyeing) in the past.Therefore, this aspect of the present invention to small part based on following understanding, promptly the friction noise level not only depends on the infringement level, also depends on other hair feature.
Each kind and standard trace are associated.This trace is the diagram of estimating when carry out said method by the friction noise of the sample of hair generation of the kind of definition.
In system of the present invention, according to above-mentioned factor, give to be wig but normally to specify a predefined kind in the test sample book of the hair of consumer's head growth.
On test sample book, implement the inventive method then, generally carry out according to the mode substantially the same with generating above-mentioned standard trace.The friction noise signal is shown with trace on screen, and this sample trace and standard trace are compared.Whether the extent of damage of assessing hair sample is more serious or slight than what estimate from above-mentioned feature then.
The amplitude of the friction noise that generates is a key factor.Especially, when trace is current as amplitude and the graph of a relation between the time, area under a curve usually and friction level proportional.
Therefore, the advantage of this system is when considering the friction level of estimating as its feature result, can accurately estimate the infringement level of any particular hair sample.For example, primary (untreated) straight hair provides the friction noise level lower than primary curly hair naturally.Therefore, in order to estimate on hair the necessity of using treatment product, the friction noise level that pre-determines the natural generation that can estimate from the related specy hair is very important.
For example, in the methods of the invention, the hair kind that accompanying drawing 5 to 10 illustrates can be used as predefined kind, and trace can be used as the standard trace.Accompanying drawing 5 shows standard trace for grey permed European hair.Accompanying drawing 6 shows the standard trace of brown curling European's hair.Accompanying drawing 7 shows standard trace for brown Asian hair.Accompanying drawing 8 shows standard trace for grey hair.Accompanying drawing 9 shows the standard trace of European's hair of brown hair-waving and bleaching.Accompanying drawing 10 shows standard trace for brown virgin European hair.From accompanying drawing 5 to accompanying drawing 10, friction level descends.This and area under a curve, and usually and the amplitude of trace proportional.
This system can directly be used by consumer, but is preferably for example used in shop or beauty parlor by operator or consultant.Can estimate, after the evaluation, may further propose suitable processing suggestion hair.
