Abstract
Fabric water imbibition method of testing provided by the invention is that fabric is absorbed into the change procedure for reaching saturation and then recording absorbed water weight and soak time by the water imbibition of itself under conditions of certain temperature humidity, embodies the water absorbing properties of fabric with regard to the absorption affinity of fabric in itself.The stage of beginning and end is removed in absorption process, obtain among uniform data be final result, it is unit interval systemic speed to represent that final result, which may also be,.Using the present invention method as water absorption of fabrics test for equipment requirement is not high, cost is relatively low, simple to operate, there is very actually active use value.
Description
Technical field
The present invention relates to Fabric Wetting Characteristics method of testing technical field.
Background technology
At present, the water imbibition method of testing of textile comparative maturity and comprehensively, such as, there is test water absorption rate and water suction
The various tests of amount.A kind of but also relative shortcoming of method for embodying water absorption and rate of water absorption simultaneously in method of testing.With
More and more to the various test requests of fabric water absorbing properties, common testing procedures can not meet client to this kind of product
Testing requirement.
If could be in same equipment, while would measure saturated water adsorptive value and rate of water absorption；Meanwhile can by water absorption and
Absorbent time dynamic bind, form a kind of water absorption-time graph, to characterize absorption process and rate of water absorption, this to client and
All it is very popular for mechanism for testing.
The content of the invention
The purpose of the present invention is that the above-mentioned deficiency overcome in existing textile water imbibition method of testing, there is provided Yi Zhongjian
Water absorption and the method for testing of rate of water absorption are measured while single, inexpensive.
It is a further object of the present invention to provide a kind of textile test device.
For the above-mentioned purpose, the technical scheme that the present invention takes is as follows：
A kind of Fabric Wetting Characteristics method of testing, comprises the following steps：
1) the damping sample in the constant temperature room of standard atmospheric pressure；
2) standard-sized sample is taken to be placed on test board；
3) vessel equipped with liquid are placed on balance, siphon pipe one end is inserted to hydraulically full below liquid level, observation day
The weight readings of stabilization on flat；
4) test board is placed in above the siphon pipe other end, makes sample fabric contact liq, according to water suction situation balance weight
Amount can gradually reduce, and record weight data and the time of change；
5) data under collating the minutes, using speed or graphical representation.
Further, described constant temperature is generally located on 20 DEG C, and humidity is transferred to 65% relative humidity.Standard-sized sample
Refer to the textile circular sample of 50mm diameters.
Further, solution of the vessel equipped at least with 200ml of liquid is held, solution is connected to test board by siphon pipe.
Further, whether observation computer initial weight is stablized, and is accurate to 0.001g.The liquid observed shown by balance is every
Second weight change, water absorption terminates to test less than 3.0mg in 5s.
Further, the 20%-80% of step 5) data intercept rate of water absorption, which becomes, turns to result, is represented with m/s.Or root
Represented according to rate profile.
A kind of textile test device, including balance, siphon pipe, the vessel and test board for holding liquid, described siphon
In pipe one end insertion vessel below liquid level, one end is connected with test board, and the vessel for holding liquid are arranged on balance.
Further, described textile test device is also associated with computer, the weight data of balance record on computers and
Display.
Beneficial effects of the present invention：
The method of testing of the present invention is to absorb fabric by the water imbibition of itself under conditions of certain temperature humidity
Reach the change procedure of saturation, the water absorbing properties of fabric are embodied with regard to the absorption affinity of fabric in itself.Gone in absorption process except
In the stage begun and terminated, it is final result to obtain middle uniform data, and it is that the unit interval is systemic that final result, which may also be,
Speed represents.
Using the present invention method as water absorption of fabrics test for equipment requirement is not high, cost is relatively low, operation is simple
It is single, there is very actually active use value.
Brief description of the drawings

Embodiment
Embodiment 1
First, as shown in figure 1, setup test device, including balance, siphon pipe, internal diameter 5mm hold the vessel of liquid, diameter
12cm height 3cm test board, the vessel for holding liquid are arranged on balance.By day flushconnection computer, the weight data of balance
Record and show on computers with numbering.
2nd, setup test
1) the textile circular sample of 50mm diameters is prepared；
2) in 20 DEG C of rooms of standard atmospheric pressure damping sample to 65% humidity；
3) standard-sized sample is taken to be placed on test board；
4) 250ml water is held in vessel, will siphon pipe one end insert liquid level below it is hydraulically full, observe balance on just
Whether starting weight amount is stablized, and is accurate to 0.001g, until data stabilization；
5) test board is placed in above the siphon pipe other end, makes sample fabric contact liq, according to water suction situation balance weight
Amount can be gradually reduced, the liquid weight change per second shown by observation computer observation balance, and water absorption is tied less than 3.0mg in 5s
Beam is tested；
6) the rate of water absorption change for intercepting the 20%-80% of step 5) data turns to result, is represented with m/s.Or according to speed
Rate graphical representation.
Thus, using test device and the method just water absorbing properties for obtaining fabric of energy simple, intuitive and the water suction of the present invention
Speed.
