Description

Fabric water permeability tester convenient to observe

Technical Field

The utility model relates to a weaving equipment technical field especially relates to a fabric water permeability apparatus convenient to survey.

Background

The water permeability tester is used for measuring the hydrostatic pressure of a sample, one side of the sample is subjected to a continuously rising pressure under the standard atmospheric condition until three places are permeated, and the pressure at the moment is recorded. Described according to step 8.4 in GB/T4744: the hydrostatic pressure at the moment the third water drop just appeared on the sample was recorded. The fine water droplets that do not grow after formation and the water droplets that continue to ooze at the same point in the fabric are not considered. If a third drop occurs at the edge of the holding device and the hydrostatic pressure value of the third drop is lower than the lowest value of other samples of the same sample, the data is rejected, and the supplementary sample is subjected to other experiments until a normal sample result is obtained.

When the drop of water appears at clamping device edge, because there is the field of vision blind area, be difficult for observing the drop of water, often can factor off the edge drop of water this moment and lead to the test result bigger than normal (have among the current three drops of water to appear in the lower pressure disk edge blind area, the third drop of water that appears in the field of vision often is the fourth drop or more). At this moment, the testing personnel is required to repeatedly carry out the testing, on one hand, the testing time of the sample is prolonged, on the other hand, the sample testing point is wasted, and when the number of the samples is limited, the testing result cannot be detected.
