Description
Technical field
The present invention relates to fire protection equipment, be particularly related to the fixture and the using method that detect for fabric freezing, this device can be used for the fixing of fabric, and this device is combined with the test that method can be used for fabric face moisture resistance, water permeability resistance, freezing.
Background technology
Fabric be by tiny soft and long thing by intersecting, around knot or the flat film piece thing that forms of bonding, the stable relation that numerous yarns form has just formed fabric.Functional fabric can and then have anti-water-sprinkling function, impervious water function, freezing function by rear arrangement, and these functions often need special instrument to measure.
Such as anti-water-sprinkling function corresponding be surperficial moisture resistance, this character can utilize the instrument that gets wet to measure by dip experiment.The structure of instrument of getting wet is comparatively complicated, main by the liquid distribution with funnel and metallic nozzle, with the support of support ring, form with the base of sample bearing, evaluates the spray rating of fabric by investigating the globule state of fabric face after trickle.GB/T 4745-2012 " detecting and assessing of textile water proof performance get wet method "
What and for example impervious water function was corresponding is water permeability resistance, and this character can utilize hydrostatic pressing tester to measure by hydrostatic test.The structure of hydrostatic pressing tester is more complicated, is mainly made up of sample holder dish, pressurised metered pump, rate of pressure rise control section and pressure display section, occurs that the pressure of three infiltration points is used as the hydrostatic pressing of fabric by fabric under certain pressure.GB/T 4744-1997 " textile fabric water permeability resistance is measured hydrostatic test "
For another example freezing, this function and anti-water-sprinkling function, impervious water function are relevant, and the fabric with high surperficial moisture resistance and water permeability resistance has high freezing.Aspect fixture, there is no fixture simple, simulation fabric that human body is worn at present.Aspect freezing detection method, can detect with image icing detection method at present, but relating to image microspur, the method gathers and mathematical operation analysis, process very complicated.In a word, the mensuration of fabric functional often needs complicated instrument and method of operating.
In actual use, in the time the correlation function of various fabrics being compared to mensuration, often can not need clearly concrete parameter values, thereby can not use complicated instrument, only adopt the method for simple, intuitive to complete the sxemiquantitative test of fabric face moisture resistance, water permeability resistance, freezing, differentiate quality by observing its physical state;
Such as, relatively the anti-water-sprinkling function of two kinds of fabrics can not need to know concrete spray rating, the globule state on only need to more identical water pouring test latter two fabric;

B), select for the device of the water permeability resistance of described half-quantitative detection fabric: fabric fixing spring plate is made up of the equal proportion rectangle steel framework of 2 connections, the dimensions of outer steel framework (1) is: 28.8cm × 24cm, 2 pedestals that extend out (11) length is 1.2cm, the dimensions of interior steel framework (2) is: 24cm × 20cm, and interior steel framework (2) is connected on outer steel framework (1) by 4 springs; The first water leg (5) and the second water leg (7) are respectively two Rectangular Water Trough, and dimensions is: long 30cm × wide 24cm × dark 10cm, has baffle plate and link position between two Rectangular Water Trough;
Use this device sxemiquantitative and detect the water permeability resistance process of fabric C to comprise:
First, 24cm × 20cm fabric C is fixed on the interior steel framework (2) of fabric fixing spring plate with fabric card (4);
Second step, the anglec of rotation regulate fixed bar (6), make to become 90 degree between the double flute collecting box of fabric fixing spring plate and level;
The hydraulic giant horizontal aligument fabric of the 3rd step, use 1L/min sprays, and stops spraying after sustained firing 1min;
The 4th step, drop to the inner water of the second water leg (7) and be weighed as 39.9g seeing through fabric;
Use this device sxemiquantitative and detect the water permeability resistance process of fabric D to comprise:
First, the fabric D of 24cm × 20cm is fixed on the interior steel framework (2) of fabric fixing spring plate with fabric card (4);
Second step, the anglec of rotation regulates fixed bar (6), makes to become 90 degree between the double flute collecting box of fabric fixing spring plate and level;
The 3rd step, is used the hydraulic giant horizontal aligument fabric of 1L/min to spray, and stops spraying after sustained firing 1min;
) aim at fabric center trickle from top to down on height, continue about the 4th step, drop to the inner water of the second water leg (7) and be weighed as 1.9g seeing through fabric;
Known by contrasting, under identical water spray intensity and the condition of time, penetrate the permeable amount of fabric C than the high 39.9g of the being > of the permeable amount 1.9g that penetrates fabric D, therefore the water permeability resistance of fabric C is poorer than fabric D;
C) device, detecting for the freezing of fabric E, fabric F under low temperature environment is selected: the dimensions of outer steel framework (1) is: 66cm × 50cm, 2 pedestals that extend out (11) length is 4cm, interior steel framework (2) dimensions is: 40cm × 30cm, and interior steel framework (2) is connected on large rectangle steel framework by 8 springs; , the first water leg (5) and the second water leg (7) are respectively two Rectangular Water Trough, and dimensions is: long 70cm × wide 50cm × dark 20cm, has baffle plate and link position between two Rectangular Water Trough;
Use the situation of wearing the clothes of this unit simulation shoulders of human body, detect for the freezing of fabric E under low temperature environment:
First, the fabric E of 66cm × 50cm is fixed on the interior steel framework (2) of fabric fixing spring plate with fabric card (4);
Second step, the anglec of rotation regulates fixed bar (6), makes to become 60 to spend to simulate shoulder between the double flute collecting box of fabric fixing spring plate and level;
The 3rd step, is positioned over this device and fabric under the low temperature environment of-5 ℃, uses the hydraulic giant of 0.1L/min to the surface sprinkling of fabric E, starts to freeze through the surface of 10min fabric E; After spraying 15min, weigh, the weight of fabric has increased 26.6g;
Use the situation of wearing the clothes of this unit simulation shoulders of human body, detect for the freezing of fabric F under low temperature environment:
First, the fabric E of 66cm × 50cm is fixed on the interior steel framework (2) of fabric fixing spring plate with fabric card (4);
Second step, the anglec of rotation regulates fixed bar (6), makes to become 60 to spend to simulate shoulder between the double flute collecting box of fabric fixing spring plate and level;
The 3rd step, is positioned over this device and fabric under the low temperature environment of-5 ℃, uses the hydraulic giant of 0.1L/min to the surface sprinkling of fabric F, starts to freeze through the surface of 3min fabric F; After spraying 15min, weigh, the weight of fabric has increased 89.7g;
Known by contrasting, under identical water spray intensity and low temperature environment, fabric E occurs that than fabric F the icing time is longer because surface is not easy wetting: 10min > 3min, the less 26.6g of the being < of the weight 89.7g that simultaneously increases ice, therefore the freezing of fabric E is stronger.
