Near infrared rapid non-destructive detection method for textile components

Abstract

The invention discloses a near infrared rapid non-destructive detection method for textile components, comprising the following steps: firstly turning on a power, switching on a near infrared spectrometer and detecting the state of the near infrared spectrometer, when detecting a textile sample, putting the sample to be detected in an accessory, determining the detection thickness of the sample according to prompts of an LED indicator light on the accessory; exposing the surface of the sample to be detected to the light emitted by a light source, and forming diffuse reflection in the interior, receiving diffuse reflection light by a detector and transiting the received diffuse reflection light into digital signals, saving the digital signals in a computer, selecting an already established model to calculate spectral signals, displaying the calculated fiber blending ratio of the sample to be detected, taking out the detected sample, cleaning the accessory, and preparing for a next detection. According to the invention, one detection is completed in no longer than 3 min, and the invention can be conveniently applied in laboratory detection of textiles, site supervision of textiles by quality supervise department, self quality control of enterprises, and the like.

Description

Technical field [0001] The present invention involves a fast detection method and attachment of textile fiber, which is a near -infrared spectrum fast non -destructive detection method with textile ingredients. Background technique [0002] Textiles are a necessity for people. my country is a major textile production and consumer country. Textiles are important textile anti -fraud projects. It is of vital to the textile trade and consumer rights of textile trade and consumer rights in my country and even the world.As far as the world is concerned, the quantitative analysis of textile raw materials, whether it is textile producers, consumers, trading relations, or government regulatory departments of various countries, attach great importance to it.In order to protect the legitimate rights and interests of consumers, almost all countries have promulgated the laws that the textiles must be labeled on the textiles, nursing methods, etc. The compulsory standard GB5296.4 "Instructions...

Problems solved by technology

NIR determination of textile products does not require pretreatment and will not be destroyed; no chemical reagents are required and no pollution is caused; the test cost is low and the analysis speed is fast. There have been successful precedents in the field of individual products in the textile industry (such as the field of individual new fibers). However, there is still a huge distance from popularization and application. The fundamental reason is that no one has established calibration models for "thousands of" textiles according to the application requirements. Once these models are effectively established, the composition analysis of textiles can be quickly solved.
