With the continuous progress of China's social economy and science and technology, modern textile industry With the continuous progress and development, the inspection technology of modern textile machinery manufacturing is gradually upgrading and becoming more and more important. At the present stage, the technology input of textile detection technology has been gradually increased in China. The mechanical research and development of high-end textile detection technology equipment is also in full swing. It has important guarantee for the high precision of modern textile detection equipment and the improvement and optimization of textile product quality. In this paper, the characteristics of modern textile detection technology are discussed, so as to further explore the development direction of modern textile detection technology.

Modern textile inspection technology, as a modern technology of textile products as the carrier, has made great progress in the development of textile testing equipment in the development of detection equipment, mechatronics and the application of computer microelectronics in recent decades. With the development of economy and innovation of science and technology, great progress has been made in modern textile technology testing indicators and types of detection equipment. More and more large capacity, intelligent and multi-functional automatic textile detection equipment has been gradually applied to textile product testing. The development and application of this new electromechanical integration equipment has marked a new era in China's textile detection technology, [1 "2]".

Characteristics of modern textile testing technology

In the current information age, electronic information technology is fully utilized in every major field of society. Automation technology, electronic communication technology and other high-end technologies have been applied in the field of textile detection. Not only has greatly improved the way and means of modern textile detection technology, but also has made a qualitative leap in the detection ability. At present, the function of modern textile testing equipment is improving, and it is developing toward automation and intellectualization of equipment. The use of such a complete testing equipment has not only completed the upgrading of the detection technology, but also developed the traditional performance testing of raw materials to detect yarn and fiber properties. Moreover, the modern textile detection technology has been analyzed.

1. modern Textile testing Technology is developing to the maximum automation. With the development of the new method of vibration, instead of weighing and measuring the single fiber with ampere, foreign high-end technology research and development organizations have developed many kinds of fineness equipment based on vibration method. With the advantages of manual operation and regulation and standard testing of fiber vibration maximum value, automatic testing of fiber density can be completed by single key operation. Because the density of fiber is not artificial judgement in the past, the accuracy of fiber density value is greatly improved. According to the test, in LH, two people operated the cotton fiber textile detection system. A total of 190 samples were tested. The test results of this detection system are basically unaffected by human operation and have good accuracy. 2. modern textile detection technology is widely applied to the current high and new technology. First, with the continuous updating of network computer technology, developed countries have introduced a new type of computer control system to control the density of textile products. It not only effectively solved the time required to control the sample's standard weight, but also avoided the error of the sample itself. Especially in the strength and elongation test of single fiber, the data of new equipment are calculated, including collection, processing and data display. The elongation at break of products is controlled effectively. At present, the technology of fiber regulation and control by computer software in China is mainly based on the computer network and the photometric detection method. The use of the computer network center to further determine the products is not only reliable and fast, but also can accurately classify the fiber products with very similar chemical composition. It can also effectively identify the blend components in fiber products. Secondly, in modern textile inspection technology, digital image processing technology has also been widely applied. Optical fiber direct analysis equipment is one of them. The use of high-end digital image processing technology to determine wool fiber, ensure the accuracy of the diameter and average diameter of wool fiber. According to the test, the test speed can basically reach ten thousand points per minute. Moreover, as an application of digital image processing technology in modern textile, optical fiber direct analysis equipment can also effectively test the crimping degree of medullary hair and fibers. Finally, in modern textile detection technology, laser technology is also fully applied. The laser scanner used in Australian textile industry is the representative of laser technology in modern textile technology. Its detection speed is no less than the speed of optical fiber direct analysis equipment, but its control technology is carried out by laser scanning and computer. Through the computer control, the diameter of the fiber is used to detect the fiber in a short time, and the CV value and the average diameter of the product are accurately determined.

3. in modern textile detection technology, sensing methods are constantly upgrading. In the modern textile inspection equipment, the audio frequency and photoelectric sensing of capacitive sensing are developing. The world's large scale sensor manufacturing companies are upgrading their audio and photoelectric sensing devices. A typical representative of the German wewayg company. The textile inspection equipment produced by the company contains an audible frequency device, the frequency of vibration is between 3Hz~5Hz, making full use of the change of fiber frequency in the principle of speed change to measure textile products. It not only keeps the density and evenness of cotton strip and roving yarn in the measurement process, but also the whole measurement results are not affected by the surrounding environment. {page_break}

Development direction of modern textile detection technology

Modern textile detection technology is developing towards analog quality inspection and evaluation. Facing the economic development at home and abroad, economic globalization and sharing of science and technology have become the necessity of social progress all over the world. In modern textile inspection technology, the influence of manual operation on product testing results has been getting smaller and smaller due to the trend of intellectualization and automation. Therefore, textile product testing is mostly based on test results to reliably simulate and predict the processing and quality of textile products. In this way, not only can effectively avoid the quality problems that may occur in the production process of small sample products, but also save the waste of production time and production costs.

Modern textile detection technology develops to high speed and high efficiency. At present, the testing speed of the high performance tensile tester for textile products by ij400m/min is 30 thousand times per hour. This speed improvement can be said to be a leap in textile detection technology. It not only provides the effectiveness and accuracy of product detection, but also improves the speed of detection and ensures the efficiency of the detection process. Modern textile detection technology is developing towards multi functions. Traditional textile product testing is only a single attribute evaluation of products. It not only takes time and manpower, but also has a large number of human factors. In modern textile inspection technology, the factors of manual operation in the process of detection are simplified, and the influence of manual operation on testing results is eliminated. Moreover, for product testing, attributes can be used to detect multiple attributes of products, such as density, length and fracture elongation, etc., and develop [3] in multi-functional direction.

With the continuous progress of modern science and technology, modern textile detection technology is also changing. With the deepening of the process of economic globalization in recent years, the sharing of industrial technology in the whole world has gradually expanded. In the modern textile detection technology, we need to strengthen international cooperation. We should introduce foreign high-end detection technology and join the scientific and technological input in textile production and testing. Spin The overall development of the industry. Establish the right direction of development.
