Embodiment Construction

[0026] As shown in Figure 1, the present invention comprises YG813 fabric wetness meter, camera and the computer that contains image acquisition, analysis and evaluation; Camera is installed on YG813 fabric wetness meter test bench directly above, and camera axis and test bench plane Vertically, the signal is connected to the corresponding interface of the computer.

[0027] The corresponding interface for the signal to be connected to the computer is a USB port or a video input port or an interface used by an image acquisition card.

[0028] Operation steps: Use a metal ring with a diameter of 6 inches (152cm) to tie the sample to the sample holder, so that the sample produces a smooth and wrinkle-free surface to be tested; place the sample holder with the sample on the tester, adjust Its position makes the trace formed by the water spray consistent with the middle of the metal ring. For twill, twill-like gabardine, piqué, and similar ribbed fabrics, the direction of the grai...

Abstract

The invention discloses an automatic detecting method and system for the fabric waterproof performance. The imaging head is installed on the top of the YG813 fabric water device test table and the axis is vertical to the test table plane; the signal is connected to the corresponding computer interface. The water-touch test system does the water touching test on the fabric, then the image collecting system gets the fabric wet track image. After treating the track image, the detection software pick the detection field and fabric wet track field to compute the wet ratio which is the ration of fabric wet area and the detection field area. It gets the relational curve between the wet ratio and the AATCC22 standard grade, the cent value and the critical value between each grade to reach the grade automatically by computer. The invention can detect the fabric waterproof quickly, accurately with low cost and high quality; also it can change in many standards to appraise the fabric waterproof impersonally.

Description

technical field [0001] The invention relates to a method and system for automatic detection of fabric waterproof performance. Background technique [0002] The so-called waterproof performance refers to whether the water on the outside of the fabric will penetrate the fabric and soak into the inside, which is commonly referred to as surface moisture resistance. Waterproof and moisture-permeable textiles are an important category of new high-grade fabrics. They have developed rapidly in recent years and are widely popular. [0003] Waterproof and breathable fabrics have a wide range of uses: [0004] Table 1 Main application fields of waterproof and breathable fabrics [0005] military uniform Winter military uniforms, combat uniforms, crew uniforms, pilots, special forces uniforms, etc. Ordinary service Casual clothes, down jackets, socks, gloves, hats, etc. work clothes Police uniforms, firefighting uniforms, surgical clothing, ...
