1. Domestic jacquard development direction with the development of international electronic and mechanical industry and the development and application of new raw materials in textile industry, jacquard machine has developed rapidly in the world in recent years. China should keep pace with the development speed as soon as possible. The author thinks that domestic jacquard machine should focus on the following aspects: with the continuous improvement of living standards, people's requirements for living environment will also be improved In the future, the proportion of jacquard fabric will be increased because of the gradual transition from plain fabric to Floral Fabric in environmental decoration, room beautification and clothing materials.
2. Due to the rapid development of electronic and mechanical industry, electronic jacquard and weaving programming system can be gradually popularized in order to improve work efficiency.
3. In order to improve the level of product automation and meet the requirements of high-speed operation of new looms, we should start to develop domestic Jacquard machines in the aspects of first evolution, electronization and high-speed. At present, there are only mechanical jacquard machines suitable for 300r / min in China, and it takes nearly a month to design, punch and modify a kind of complex pattern fabric with wood pattern paper. Both quality and efficiency can not meet the needs of the market. Through the performance analysis of foreign electronic jacquard machines, it can be seen that the advantages of high-speed electronic jacquard are as follows: first, high speed, suitable All kinds of rapier, shuttle, water jet and air jet looms of ying250 can increase the production efficiency by 2 ~ 3 times; Second, the independent pattern design system is adopted to control the change of pattern organization of electronic jacquard machines in the workshop. From the international textile machinery exhibitions over the years, the prototype equipped with high-speed electronic jacquard machine accounts for almost 60% of all looms. However, this field is still blank in China. It is predicted that the demand of domestic textile users for this machine will increase by 30% every year. At present, the domestic production of rapier, air jet and water jet looms has formed a batch production capacity of 17000 sets / year. According to the most conservative forecast, if equipped with high-speed electronic jacquard machines at 3%, there should be a market demand of 500 sets / year. Therefore, the research direction on high-speed electronic jacquard machine will help to improve the manufacturing level of electronic jacquard machine in China, so as to produce jacking and save foreign exchange.
4. In order to facilitate the development and competition of new products, it is necessary to gradually make domestic production enterprises develop from miniaturization to collectivization and integration, make products develop from single to diversified, and gradually establish multi variety and specialized loom shedding production base.
In order to keep up with the pace of the times, we must have our own innovative products. Therefore, it is imperative to introduce foreign advanced technology and develop domestic high-speed electronic jacquard machine. The production practice of changing cotton spinning equipment to fancy yarn is imperative. For fancy yarn fabric, foreign developed countries have larger demand, while domestic demand is relatively small. This demand reflects the level of people's purchasing power and the cost of fancy yarn manufacturing Contradictions, and people's understanding of fancy yarn fabrics. Efforts to reduce the manufacturing cost of fancy yarn and develop fashionable fancy yarn with low price and high quality are the key to develop the international and domestic market of fancy yarn and its fabric. The purchase price of fancy twister is tens of thousands to hundreds of thousands per set, and only 25 spindles, accounting for about half of the spinning frame area. The equipment investment is high, and the number of running spindles is small and the operation cost is high. The price of a fancy twister made from a common spinning frame is less than 1000 yuan. Each set has 416 spindles, which can be used as 7-8 regular fancy twisters. When fancy yarn is not spun, the ordinary yarn can be spun as long as some parts are restored. The disadvantage is that some fancy yarn can be spun by the modified fancy twister with two twists, while the hollow spindle fancy twisting machine can be twisted at one time.
