Automatic measuring device and method for evaporation rate of textile

Abstract

The invention relates to an automatic measuring device and method for evaporation rate of a textile, comprising an evaporation tank and a weight inductor, wherein the evaporation tank is placed on theweight inductor, holes are formed in four walls of the evaporation tank, an evaporation platform is arranged inside the evaporation tank, the evaporation platform is composed of a telescopic supportarranged at a center position of the evaporation tank and a non-absorbent flat plate at the upper end of the telescopic support, a humidity sensor and a temperature sensor are arranged on the non-absorbent flat plate, one water channel is formed in the lower part of the evaporation tank, a fan is erected at one side of the evaporation tank, a wind speed sensor is arranged at a position, close to the fan, of the evaporation tank, and the wind speed sensor, the humidity sensor, the temperature sensor, the weight inductor and the fan are respectively connected with a control computer. The automatic measuring device provided by the invention can automatically determine parameters, such as single-side and unit evaporation area and amount of water evaporated in unit time, of a sample under specified environmental conditions and is small in measurement difference.

Description

technical field [0001] The invention relates to the field of textile testing, in particular to an automatic measuring device and method for the evaporation rate of textiles. Background technique [0002] Evaporation rate refers to the amount of water evaporated per unit time and per unit area of ​​textiles under constant temperature and humidity conditions, and is an important indicator of the quick-drying performance of textiles. [0003] At present, the quick-drying performance of domestic textiles is tested using GB / T 21655.1-2008 "Assessment of Moisture Absorption and Quick-drying of Textiles Part 1: Single Combination Test Method", which stipulates that the sample should continue to test the water evaporation rate after testing the drip diffusion time. The total amount of water is 0.2g, and the mass is weighed every 5 minutes until the change rate of two consecutive weighings does not exceed 1%, and the water "evaporation rate" is calculated according to the time-evapor...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the impregnated sample no longer drips water, which means that the sample is in a state of saturated water absorption. The saturated water absorption of different types of samples, that is, the hygroscopic performance is different, so the measured drying time includes the moisture absorption of the sample. performance impact, not "evaporation rate"

[0005] Furthermore, the evaporation rate on both sides of the textile may be different due to the difference in raw material distribution, organizational structure and finishing method, and the methods in the existing standards cannot measure the difference

[0006] In addition, too much manual intervention in the existing standard test process will affect the evaporation of water in the sample, thus affecting the accuracy and stability of the test results
