Abstract

A method for detecting textile structure and dyeing defects by using an infrared laser comprises: projecting an infrared laser to a fabric sample, collecting an infrared laser transmission image of the fabric sample, and displaying the infrared laser transmission image of the fabric sample on a display device. A device for detecting textile structure and dyeing defects by using infrared laser, which is composed of a semiconductor laser and an infrared camera. The semiconductor laser and the infrared camera are respectively fixed at both ends of an optical path. A fabric sample holder is arranged in the optical path, a condenser lens is arranged in the optical path between the semiconductor laser and the fabric sample holder, an objective lens is arranged in the optical path between the fabric sample holder and the infrared camera device, the infrared camera device and a display connect. The infrared laser transmission image of the textile material with gray scale and contrasting color is displayed on the display device, and the image is used for technical analysis and identification.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to optical detection technology, in particular to a method and device for detecting textile structure and dyeing defects by using infrared laser. Background technique: [0002] Textiles may have defects in their structure and dyed materials during their manufacture.
