Embodiment 2
This method of testing is further explained by the present embodiment.
A kind of method of testing of dry rate when adding a certain amount of water under the environment of 37 ° of C of skin temperature when this method is positioned proximal to perspire for test fabric.
The temperature of hot plate is by one piece of flexible heater sheet and a PT100 temperature sensor, adds what single-chip microcomputer controlled, and overheated because of what surprisingly cause by a temperature protection switch protection.The power supply of heating wire is powered by Switching Power Supply.During heating, PT100 temperature sensor feedback signal is to single-chip microcomputer, and when temperature rises to set point (37 ° of C), single-chip microcomputer can reduce to power supply, to maintain stable temperature.Here single-chip microcomputer control to adopt the mode of dutycycle, Switching Power Supply provides stable power supply, by Single-chip Controlling heat time heating time.When temperature from set point distant time, the duration of heat is longer, and when temperature solve set point time, heat time heating time shorten, the heat-up periods time is elongated.
The horizontal gas flow of yarn fabric sample surfaces to be measured is added what guide plate produced by having by vertical bellows, and air velocity requires to control at 1.5 meter per seconds.The measurement of air-flow is completed by a hot wire anemometer.The wind speed that anemometer records feeds back to single-chip microcomputer, then has Single-chip Controlling to the power supply of fan, completes the closed loop control to wind speed.
Yarn fabric sample surfaces to be measured process of dripping is completed by plunger displacement pump.Plunger displacement pump two ends are respectively arranged with a Unidirectional solenoid valve, and one is used for fabric water filling, and one is used for plunger displacement pump moisturizing.The moisture of 0.5 milliliter can be dripped on fabric for 2000 times by this precision plunger pump.The control of plunger displacement pump is completed by single-chip microcomputer.
The change of yarn fabric sample surface temperature to be measured then has an infrared temperature sensor to measure, for non-contact measurement mode.The drip change of front and back temperature of yarn fabric sample to be measured has this temperature sensor to monitor, and this series of data is uploaded to upper computer software, upper computer software judge whether fabric reaches the state dried.
The computer used when infrared temperature sensor data are transferred to test collected by single-chip microcomputer.After recording temperature, taking 7 points at the most steep part of temperature-time curve, returning to the flat part after near equilibrium temperature 37 DEG C in temperature takes 25 points, then passes through use equation of linear regression and finds two straight lines.Article two, the abscissa of straight-line intersection needs to use the test end time when being final calculating.Then dry rate R is obtained with the amount of dripping V divided by the testing time.
Finally should be noted that; above example is only in order to illustrate technical scheme; but not limiting the scope of the invention; although having made to explain to the present invention with reference to preferred embodiment; it will be understood by those within the art that; technical scheme is modified or equivalent replacement, all belong to protection scope of the present invention.
