Problems solved by technology

Using the non-destructive testing method, although it does not damage the sample, and can realize online and rapid measurement, but because it is based on the statistical analysis method and is calibrated based on the results of the oven method, the results are biased and there are many interference factors. The stability and accuracy of the results are affected

Abstract

The invention relates to a measuring method and an apparatus used for quickly measuring the water content in textile (fiber assembly, yarn, fabrics and membrane). The method is realized as follows: the hot air is injected into one end of a sample-bearing cylinder to accelerate water evaporation; the hot air is output from the other end of the sample-bearing cylinder to quickly discharge water content; the water content of the textile can be measured through weighing the mass of the sample-bearing cylinder. The apparatus used for realizing the method comprises a sliding door used for regulating the air flow, an induction furnace used for heating air, a fan used for controlling the air flow, the sample-bearing cylinder connected with a force sensor, an electromagnetic drive mechanism and a box used for driving an exhausting system, a signal collecting and input system, a mechanism drive control module, a program software and a computer. The invention is characterized in that the quick measurement to the water content of textile can be realized; the structure is simple; the mechanism is delicate; and the measurement can be realized conveniently and quickly.

Description

technical field [0001] The invention belongs to the technical field of textile precision measuring instruments, and relates to a method and a device for measuring moisture content of fiber aggregates, yarns, fabrics and films in textiles. Background technique [0002] The moisture content of textiles will affect its effective weight, performance and shape, so the research on the moisture content of textiles is extremely important. The effective way to study the moisture content of textiles is to carry out objective and accurate instrumental measurement and characterization. [0003] At present, the methods for measuring the moisture content of textiles can be divided into rapid weight loss detection and rapid non-destructive detection. The former is also a direct measurement method, that is, a method of directly obtaining the weight of water in textiles. The principle is to weigh the actual weight and the weight after water has been removed to obtain the water content. Acc...
