Abstract
This invention improves the precision with which the drying speed of a fabric is measured, even with respect to the tolerance range for a reference state. A water application unit (1) causes water to adhere to a test piece (20) of a fabric. A holding unit (2) holds the test piece (20) in a stationary, spread-out state. With the wet test piece (20) held by the holding unit (2), a mass measurement unit (3) continuously measures the mass of said test piece (20) and stores each mass measurement in association with the elapsed time at the time of said measurement. During the period over which the mass measurement unit (3) is measuring the mass of the test piece (20), a temperature/humidity measurement unit (4) continuously measures the temperature and humidity at a prescribed position on the test piece (20) and stores each temperature and humidity measurement in association with the elapsed time at the time of said measurement. Using the temperature and humidity measurements performed by the temperature/humidity measurement unit (4), a temperature/humidity normalization unit (8) expresses mass changes measured by the mass measurement unit (3) in terms of prescribed temperature and humidity conditions.

(embodiment 1)
Fig. 1 is the frame of the configuration example of the rate of drying determinator illustrating embodiments of the present invention 1
Figure.Rate of drying determinator 10 is by water assigning unit 1, maintaining part 2, quality determination portion 3, humiture
Determination part 4 and control portion 5 are constituted.Control portion 5 comprises storage part 6, humiture normalization portion 8 with
And timing unit 7.
Rate of drying determinator 10 measures the water of attachment on the test film 20 of cloth and does after attached water
Dry speed.The water of attachment is maintained in the gap of fiber after penetrating into test film 20, therefore root
According to the material of test film 20, dry speed there are differences.
Before measuring rate of drying, under the standard state measuring rate of drying, temporarily place test
Sheet 20, adjusts in the way of the temperature of test film 20 and moisture do not change
Wet.In rate of drying device, on test film 20 before attached water, the matter of determination test sheet 20
Amount.Can be measured by quality determination portion 3 when test film 20 is maintained at maintaining part 2
The quality of test film 20.Quality determination portion 3 measures the total quality of maintaining part 2 and test film 20.As
Fruit measures the quality of maintaining part 2 in advance, then poor according to these, it is known that the quality of test film 20.
In water assigning unit 1, for test film 20, by a certain amount of water loading on the rule of test film 20
Location is put, such as, be attached to central authorities.In water assigning unit 1, such as, by pipette, (metering is inhaled
Pipe, trace pipette) a certain amount of water is measured, and drip on test film 20.Can lead to
Cross syringe pump or infusion pump to drip on test film 20.Or, test film 20 can be spread out and energy
Drip on enough containers flatly received a certain amount of water, loads attached above it by test film 20
Water.
Then, water test sheet 20 will be attached with to be maintained in maintaining part 2.Maintaining part 2 is spreading examination out
This test film 20 of static holding under the state testing sheet 20.Maintaining part 2 such as clamps one side of test film 20
At least some of and hanging test sheet 20.In the case of in a reservoir for test film 20 attached water,
It can be the structure kept together with container.
Even identical humiture, because blow to the intensity of the wind of test film 20 different and in dry speed
Difference is produced, it is therefore desirable that make the wind blowing to test film 20 constant on degree.At hanging test sheet
In the case of 20, when wind is blown to, test film 20 rocks and can not quality measurement exactly.Preferable
If, permissible, cover test film 20 with windscreen so that wind is less than this test film
On 20.
Quality determination portion 3 is such as made up of, at the shape being kept test film 20 by maintaining part 2 accurate Libra
Under state, continue the quality of determination test sheet 20.It has been observed that quality determination portion 3 measures maintaining part 2 He
The total quality of test film 20, but owing to the quality of maintaining part 2 is fixing, therefore determination test sheet
The quality of 20.The quality measured is delivered to control portion 5 by quality determination portion 3.Control portion 5 will receive
Quality corresponding with the elapsed time of (during the quality of reception) during quality measurement be stored in storage
In portion 6.
The elapsed time is measured by timing unit 7.The most built-in table of timing unit 7, export by during reference time
Carve data.It is to deduct to determine for the first time from the moment determining quality to be attached water test sheet 20
Quality time moment obtained by value be the elapsed time.When starting to measure, timing unit 7 is carried out multiple
Position, exports and starts the elapsed time of (0) as initial point with mensuration.
Humiture determination part 4 is supported at fixed position relative to test film 20, for test film 20
Continue to measure the temperature at fixed position and relative humidity.Hereinafter, humidity refers to relative humidity.Reason
Thinking, the position measuring temperature and humidity is close to attachment in the range of not contact test sheet 20
There is the part of water.In the case of covering test film 20 with windscreen, humiture determination part 4 is arranged on
The inside of windscreen, in the intraassay temperature and humidity of windscreen.Humiture determination part 4 determination test sheet
The temperature and humidity of the air of 20 weeks.The temperature and humidity measured is delivered to by humiture determination part 4
Control portion 5.Control portion 5 by the temperature received and humidity and mensuration these time (receive temperature and
During humidity) elapsed time corresponding be stored in storage part 6.
When measuring humidity, such as, can use according to the dry-bulb temperature measured by psychrometer and wet bulb
Temperature, the method obtaining relative humidity by humid air line chart or calculating.Or, it is also possible to
Drimeter is used to measure relative humidity.Such as, the humidity that will be measured by electric hygrometer, with

It is scaled the temperature of regulation and the condition of humidity and is normalized.When indicating normalization,
The change of the quality measured so far can be scaled the temperature of regulation by humiture normalization portion 8
And the condition of humidity.
Fig. 3 is the figure of the concept of the temperature and humidity conditions being normalized to regulation illustrating embodiment 1.Horizontal
Axle is the elapsed time, and the longitudinal axis is the quality of test film 20.Institute is represented by the actual measurement quality of solid line
The quality of the test film 20 measured.Fig. 3 is denoted as measured temperature higher than the condition as conversion
The temperature (standard temperature) of regulation, or the humidity measured is less than as the condition converted
The situation of the humidity (standard humidity) of regulation.Now, it is common that with standard temperature and standard humidity
Condition (standard atmosphere condition) compare, moisture promptly evaporates, therefore actual measurement quality along with
Time process, the quality under the conditions of becoming than standard atmosphere is little.
The matter of the identical test sheet 20 supposed when being dried velocity determination under standard temperature and humidity
Amount is represented by the quality=normalization quality of two dashdotted standard atmosphere conditions.Standard atmosphere
The quality (change) of condition can be by changing the rate of drying under the temperature measured and humidity
Calculate and calculate for the rate of drying under standard temperature and humidity.When converting rate of drying, use institute
Steam under the temperature and humidity measured divides the steam under difference and standard temperature and humidity to divide
Difference.Known that by calculated in advance the steam under standard temperature and humidity is poor.
Test film 20 before the quality of adhesive water and test film 20 in measuring and adhesive water
The difference of quality (test film dry mass) is residual moisture.Residual moisture (is composed with accompanying moisture
Give moisture) ratio be residual moisture rate.Can be by being standard temperature and wet by actual measurement mass conversion
Normalization quality obtained by degree (two chain-dotted lines of the quality under the conditions of=standard atmosphere: Fig. 3),
Residual moisture rate under the benchmark elapsed time (the some N of Fig. 3), the dry speed of evaluation test sheet 20
Degree.At benchmark in out-of-date, residual moisture rate is the biggest, then rate of drying is the slowest, residual moisture rate
The least, then rate of drying is the fastest.
In the above description, mass change is scaled the condition of standard temperature and humidity, it is possible to
To consider that the benchmark elapsed time changes with temperature and humidity.I.e., think in the temperature measured
And under humidity, if the evaporation of moisture is fast compared with under the conditions of standard atmosphere, benchmark warp
The time of mistake shortens, if compared with under the conditions of standard atmosphere, if the evaporation of moisture is slack-off, and base
The quasi-elapsed time is elongated.The normalization coefficient in elapsed time now can also use steam to divide
Difference calculates.Such as, calculate by the normalization coefficient next normalized elapsed time (during normalization
Between) become on the basis of elapsed time (Actual Elapsed Time) in elapsed time.Then, by actual warp
Cross the actual measurement quality under the time and regard the quality of the standard atmosphere condition under the benchmark elapsed time as, meter
Calculate residual moisture rate.Below it is described in detail.
Saturated steam e (T) at temperature T (DEG C), can be by following Aug
Formula beyond ust represents.
E (T)=6.1078 × 10(7.5T/(T+237.3))
If: dry-bulb temperature: Td (DEG C), wet bulb temperature: Tw (DEG C), relative humidity
RH (%), divides liquid phase water steam and is expressed as Pww=e (Tw), by gas phase water
Steam divide be expressed as Pwa=e (Td, then steam divides poor Δ Pw as follows:
Δ Pw=Pww-Pwa.
When measuring wet bulb temperature, from wet bulb temperature it is known that liquid phase water steam divides.Measuring
During relative humidity, according to temperature and relative humidity, humid air line chart, obtain wet bulb temperature, meter
Calculate liquid phase water steam to divide.
Standard conditions are set to: when standard temperature is 20 DEG C, standard humidity is 65%, as now
The standard wet bulb temperature of wet bulb temperature be Twstd=15.83633 DEG C.Under standard conditions
Steam divides difference to be Δ Pw_std=2.79476319.
The quality of the test film 20 before attached water is set to Wf, by when starting after attached water to measure
The quality of test film 20 be set to Wa0.The quality of accompanying moisture is Ww=Wa0-W
f。
If the quality of the test film 20 under elapsed time ti is W_i.If elapsed time ti and ti-1
Between average dry-bulb temperature be Td_i, wet bulb temperature be Tw_i, relative humidity be RH
_i.Steam now divides difference Δ Pw_i to represent.Steam under standard atmosphere is divided
Difference Δ Pw_std and the steam under the humiture measured divide the ratio of poor Δ Pw_i, if
For normalization number K_i.I.e.,
K_i=Δ Pw_std/ Δ Pw_i.
Moisture before from elapsed time ti-1 to ti is set to Δ W_i=W_i-1 on a small quantity
-W_i, when the difference of elapsed time ti Yu ti-1 is set to Δ ti=ti-ti-1, during this
Rate of drying R_i be
R_i=Δ W_i/ Δ ti
.Assume that the water that can ignore evaporation quickly spreads, the air of the vicinity of the part of water evaporation
Humiture and away from local air humiture between difference, then it is believed that rate of drying with
Steam divides difference proportional.Under this condition, the rate of drying R_i measured is scaled mark
After normalization obtained by quasi-humiture, rate of drying R ' _ i can use
R ' _ i=K_i R_i
Represent.
Therefore, moisture a small amount of Δ W ' _ i between the Δ ti under standard state is
Δ W ' _ i=R ' _ i Δ ti=K_i R_i Δ ti.
Under standard state Δ, within the period of ti, quality changes delta W of test film ' _ i, if
If it is patterned, it is possible to obtain the figure-of-merit curve under the conditions of standard atmosphere.According to standard
Figure-of-merit curve under temperature and humidity conditions, such as, calculate the matter under the benchmark elapsed time by interpolation
Amount, then it is known that residual moisture rate under the benchmark elapsed time.
Can be according to the formula of moisture a small amount of Δ W ' _ i between the Δ ti under standard state, it is believed that
Elapsed time difference Δ t_i when on the contrary, measuring under standard atmosphere becomes 1/K_i times.Permissible
During the normalization that will obtain so that elapsed time difference Δ t_i is normalized by normalization number K_i
Between the aggregate-value of Δ t ' _ i=Δ t_i/K_i become on the basis of the elapsed time, the elapsed time (real
The border elapsed time) quality W_n under t_n sees the matter in the benchmark elapsed time under standard state as
Amount.In the case of on the basis of one-tenth, the last elapsed time difference in elapsed time becomes zero number, in proportion
Calculate.According to quality W_n under Actual Elapsed Time t_n, calculate residual moisture rate
Mc=(W_n-Wf)/Ww
, can be as the residual moisture rate in the benchmark elapsed time under the conditions of the standard atmosphere of this test film 20.
If it addition, normalization number K_i is fixing, then can will be multiplied by the benchmark elapsed time
As Actual Elapsed Time obtained by normalization coefficient.
