Modern textile technology has developed very rapidly in the original textile technology. With the continuous development of science and technology and the research and development of sexual materials, textile technology has more and more demanding requirements on technology and efficiency. Here, Standard Group will introduce you to the development of textile technology. process. 1. The development of traditional textile technology to modern textile technology textile production has a history of thousands of years. As early as 5000 BC, there was textile production in the birthplace of world civilization. Linen textiles in the Nile River Basin in Africa, kudzu and silk textiles in the Yellow River Basin and Yangtze River Basin in my country, and cotton textiles in the Indus River Basin. In 500 BC, there were hand-spinning wheels and pedal looms in our country. Among the more than 200 silk and linen textiles unearthed in the Western Han Dynasty tombs at Mawangdui, Changsha, Hunan in 1972, one of the plain yarn Zen clothing weighs only 49 grams. After the 16th century, European hand-made textile machines have been greatly improved. In the second half of the 18th century, the industrial revolution was first set off in the
textile industry in Western Europe, with the emergence of water-driven spinning machines. At the end of the 18th century, textile mills began to use steam engines, and industrial production has since replaced household manual weaving. The industrialization of textile production has promoted the continuous improvement of textile machinery. Due to the large number of employees in traditional textile technology, low labor productivity, and high labor costs, a large amount of textile production in developed countries has shifted to developing countries with lower labor costs. In 1924, the British cotton textile industry reached a scale of 63.3 million spindles and 792,000 looms. The cotton spinning spindles in the United States and Japan have reached 36.2 million and 13 million spindles respectively. With the passage of time, the leading industries that have made great contributions to the accumulation of funds and economic development of these countries are regarded as sunset industries and have withdrawn from the status of pillar industries. After the middle of the 20th century, with the development of world science and technology and social economy, especially since the 1970s, electronic information technology has been widely used in textile production. Textile technology has continued to develop in the direction of high quality, high yield, automation, and continuity. A way to drastically reduce employment and raise labor productivity. In the late 1980s, a fully automatic spinning factory first appeared in Europe. Only 6 people were used to manage 10,000 cotton spinning spindles per shift. Traditional spinning technology entered a stage of modern development. Second, the development trend of modern cotton textile technology 1, the main feature of modern textile technology is intelligent production The traditional spinning technology is mainly characterized by manual operation. In the 1950s, international cotton textile production began high-speed trials. The high-speed and high-yield carding machine creates conditions for the direct connection of the opening and cleaning and carding processes. After the 1970s, the international cotton textile technology is dominated by electronic information technology, based on new materials and high-precision automated mechanical processing technology, using optical, mechanical, electrical, pneumatic, hydraulic and other sensing technologies and frequency conversion speed regulation and other transmission technologies. Developed generations of modern new equipment, realized the online detection, display, automatic control and automatic adjustment of various technological parameters in the textile production process, and realized automatic monitoring, display, over-limit alarm, self-stop, and even automatic failure of equipment operation. exclude. Highly automated production equipment can strictly follow the set process requirements and realize various simple and repetitive manual operations that rely on the technical proficiency of workers in traditional textile production with qualitative, quantitative, and standardized mechanical actions, ensuring and improving product quality. Improve production efficiency, reduce product costs, and enhance product competitiveness. The photoelectric detection, pressure sensing, displacement sensing, signal conversion, servo system control, computer processing, frequency conversion speed regulation, autoleveling, computer integrated monitoring and other technologies adopted in the single blower and carding process have improved the stability of the entire process operation. The performance and reliability ensure the continuous, synchronous and stable operation of the whole process, so that the uniformity of long, ultra-long, and even short sliver output can be stabilized within a certain range, thereby ensuring the stability of yarn quality . The foreign fiber online automatic detection and removal device developed in recent years uses color digital camera technology to correct the difference in illuminance through surface scanning. Spectral analysis can accurately determine the size and position of foreign fibers, and the foreign fibers are discharged by high-speed airflow. The whole automatic doffing and automatic winding of the long spinning car, and the continuous improvement of the air splicing technology, made the fine entanglement technology entered the practical stage in the mid-1980s. The direct connection of the two processes that employ the most people and the greatest labor intensity in cotton spinning production not only guarantees and improves product quality, drastically reduces the number of people, and improves labor productivity, but also solves the long-term difficult problems in spinning production. The contradiction between spinning speed and spinning package greatly increases the spinning speed of ring spinning frame. The technology of fine entanglement is a symbol of the development of cotton spinning production from traditional technology to modern technology.
