Abstract

The invention discloses a method for detecting textile structures and dyeing defects through infrared laser, which comprises projecting the infrared laser on a textile sample, collecting infrared laser transmitting images of the textile sample, displaying the infrared laser transmitting images of the textile sample on a displaying component. A device for detecting textile structures and dyeing defects through infrared laser is composed of a semiconductor laser and a infrared photography device, wherein the semiconductor laser and the infrared photography device are arranged fixedly on two ends of an optical path, a textile sample holdfast is arranged in the optical path which is between the semiconductor laser and the infrared photography device, a piece of condensing lens is arranged on the optical path which is between the semiconductor laser and the textile sample holdfast, a piece of object lens is arranged on the optical path which is between the textile sample holdfast and the infrared photography device, the infrared photography device is connected with a display. The infrared laser transmitting images of textile materials with grey scale and contrasting chrominance are displayed on the displaying component. The infrared laser transmitting images are provided for technological analysis and identifications.

Description
