Domestic loom share increased reliability reliance

After many years of development, domestic-made shuttleless looms have continuously improved their technical level. At present, the market share of domestic looms has accounted for almost 10%. How do users evaluate domestic looms? The statistical results of the questionnaire on the use of the "Haifu Cup" looms provide us with answers.

Obvious user evaluation of domestic equipment is only "general"

After years of continuous efforts by loom manufacturing companies, the technological progress of domestic looms can be said to be obvious to all. However, in the questionnaire survey, only 22% of the companies considered the domestic looms to be “good” and “very good”, while 97% of the companies considered the imported looms to be “good” and “very good”, indicating that the looms produced by users in China are Imported looms still have a considerable gap.

According to the statistical results of the survey questionnaire, the user's overall impression of domestic looms was evaluated as 78% of the “general” and only 19% of the respondents answered “good.” Only two users considered the domestic looms to be “very good”. There are only two users who have evaluated the overall impression of imported looms as "general", and the ratio of "good" and "very good" is 97%, of which 73% of respondents answered "good" and answered "very good." Accounted for 24%. It can be seen that the overall impression of most users on domestic looms is “general” and the overall impression of imported looms is “good”.

After years of continuous efforts by loom manufacturers, the technological progress of domestic looms, especially rapier looms, can be said to be obvious to all. The domestic rapier loom has been through the initial technology introduction cooperation and has been digested and re-innovated for many years. The models have evolved from the simple type, the introduction of cooperation type to the high-tech type of today's technological innovation, and the level of technology has been continuously improved and gradually matured. Domestic high-end rapier looms have a strong competitive edge in terms of cost performance and are gradually replacing imported brands. Domestic air-jet looms have also made significant progress. However, in the questionnaire survey, only 22% of companies believe that domestic equipment is “good” and “very good,” indicating that there is still a considerable gap between Chinese loom and imported looms.

Where exactly is the gap? From the comparison chart of advantages and problems between domestic looms and imported looms, it can be seen that the strengths of domestically produced equipment are almost always the weaknesses of imported equipment, and vice versa. The main advantages of domestic looms are focused on reasonable prices, cheap parts, good after-sales service, and easy maintenance. The main advantages of the imported looms are focused on good manufacturing quality, high degree of automation, high reliability, and ability to meet process requirements.

In the evaluation of merits, it can be seen that the prices of home-made looms and accessories are most liked by users. To a certain extent, domestically-made equipment is reasonable in price, and there is no huge profits; but from another perspective, blindly competing at low prices may cause equipment manufacturing quality to decline and the configuration to be simplified. Instead, it will damage the image of equipment manufacturers and affect companies. development of. In terms of after-sales service and maintenance, domestic looms enterprises have the natural advantages of the region and culture, understand the needs of users, and establish a good relationship with users. Many companies have a huge service team and the service is very timely and thoughtful. In contrast, some imported equipment is difficult to operate, and the structure is complex and sophisticated. In the event of a failure, maintenance is inconvenient.

In terms of automation, reliability, manufacturing quality, and brand trust, domestic looms are far lower than imported looms, and this is also a major problem with domestic looms. The user's good impression is not obtained by the effort of overnight. Foreign advanced looms manufacturing companies often put manufacturing quality first. After decades or even hundreds of years of development, they have gained goodwill and trust from users, and have maintained a leading edge in technology. The domestic looms manufacturing companies must win the price in the fierce market competition first to take advantage of the price, and this is usually at the cost of reducing equipment manufacturing quality and the quality of parts and components. The "manufacturing quality is poor", "the quality of the supporting parts is not high," and "the reliability is low" is the main problem that the user believes that the domestic looms exist.

On the other hand, some respondents lacked understanding of domestic looms and had some prejudice. Some enterprises that still use a large amount of shuttle weaving machines do not understand the functions and degree of automation of the new domestic looms, and have not seen the development of domestically produced equipment. In addition to vigorously improving product quality, domestic looms manufacturing companies also need to strengthen their publicity and promotion efforts to assist users in product restructuring.

Domestic looms account for nearly 60% of the rapier looms. The highest degree of acceptance of the 5 looms. The domestic looms accounted for 58.84%, and the imported equipment accounted for 41.16%. The domestic equipment was dominant in quantity. The most highly recognized home-made shuttleless looms are rapier looms. The increase in manufacturing quality and reliability of domestic rapier looms has been recognized by users.

The results of the questionnaire survey showed that, in view of the total number of owned 5 kinds of looms, the domestic looms accounted for 58.84%, the imported equipment accounted for 41.16%, and the domestically produced equipment was dominant in terms of quantity. The highest share of domestic equipment market is shuttle looms, almost all made. Followed by water jet loom and rapier looms, respectively, 74.47% and 68.93%. The most widely used weaving looms are shuttle looms and air jet looms, and there are fewer users of water jets and projectile looms.

The questionnaire also investigated issues such as "a domestic looms that are relatively satisfactory", "home-made looms with better manufacturing quality and reliability," and "what kind of domestic looms can completely replace imports." The rapier loom was the most recognized one, followed by shuttle loom and air jet loom. It can be seen from the above that the situation of home-made looms with high user ratings is basically in line with the situation of users. The increase in manufacturing quality and reliability of domestic rapier looms has been recognized by users.

Why domestic high-grade rapier looms can be praised by users? On the one hand, driven by market demand, the technical level, reliability, stability, and product quality of domestic rapier looms have been improved in continuous innovation, and have been able to meet the needs of different users. In recent years, the market demand for personalization has brought vitality to domestic high-end rapier looms. The market's demand for fabrics has changed from the previous large batches to small batches, varieties, and rapid reactions. The rapier loom has adapted to this demand with its flexibility, versatility, and wide variety of adaptability. The increase in the production of high-grade fabrics has stimulated the production of rapier looms, and has also given impetus to the development of domestic high-end rapier looms. Domestic rapier weaving machine has implemented the design concept of standardization and modularization in the areas of intelligentization, automation, and application of various varieties, and solved the contradiction between product batch and individual customization. Not only is it convenient to provide a variety of products to meet the needs of different users weaving different varieties, but also further lays a good foundation for product innovation. At the same time, many innovations have also been made in the main transmission mode, the manner in which the swords are used to hand over weft yarns, the form of rapier operations, the development of products (such as industrial fabrics, fabrics for different types of fabrics, etc.), and the reduction of energy consumption. Improve. Domestic rapier looms such as TT-828 from Zhejiang Titan and “Beyond” and “Classic” from Guangdong Fengkai, the normal weaving speed is basically above 500 r/min, and the adaptability and diversification of varieties The level of automation has been greatly improved. Production and sales have been booming in the past two years, indicating that the domestic high-end rapier weaving machine has received market recognition. On the other hand, domestic high-end rapier looms have now been truly industrialized, shortening product development cycles and reducing product costs. Compared with imported advanced rapier looms, domestic high-end rapier looms are highly competitive in terms of cost performance. This also further satisfies the requirement for domestic textile companies to continue to upgrade their grades while also reducing equipment costs.

Like rapier weaving machines, due to the high speed of air jet looms and the increasing adaptability of fabric varieties, the current market demand is large. However, from the statistical results of the questionnaire, it can be seen that the imported air-jet looms currently occupy a major market share of 83.6%, domestic air-jet looms only 16.4%, indicating that there is still a large gap between domestic air-jet looms and imported air-jet looms.

From the 1980s onwards, domestic companies began to develop and manufacture air-jet looms. Xianyang Textile Machinery, China Textile Machinery, and Shenyang Textile Machinery used imported technology and combined technology and production to produce Japan's Tsuda, Toyota and Nissan models respectively. At present, the supporting capacity of domestic air-jet looms has been greatly enhanced. In particular, the electronic control system that restricts the production capacity of domestic air-jet looms has been continuously explored for many years to gradually achieve localization. The functionality and reliability of electronic control systems Stability has greatly improved. However, domestic air-jet looms have problems such as relatively poor reliability of the whole machine and weak weaving process debugging techniques.

The quality and reliability of manufacturing have been concentrating on users, improving the quality of machine manufacturing and improving the reliability of machinery. It is a major issue that everyone considers that home-made looms should be emphasized in development. It is also a gap between domestic looms and imported looms. . How to produce products with low price and good quality and high reliability is a major issue facing domestic looms manufacturing companies.

In the “Main Issues for the Development of Home-made Looms”, the topic setting covers all aspects of the development of domestic looms, including the compatibility of weaving varieties, the reasonable selection of the performance of accessories, the improvement of machine manufacturing quality, and the improvement of machinery. There are 10 options for automation and intelligence, selection of high quality machine materials, and increased mechanical reliability. Among them, improving the quality of machine manufacturing and improving the reliability of machinery is the main issue that everyone thinks should be the most important, and also has a large gap between domestic looms and imported looms.

Poor manufacturing quality and reliability are long-standing obstacles to the development of domestic looms. Taking air-jet looms as an example, the average trouble-free working time of imported looms reaches 4000 hours, and the average time for failure-free working of domestic air-jet looms that have been mass-produced in China is only about 2,500 hours. There is a big gap, especially in the early failure rate. Although many years of improvements have been made by textile manufacturing companies, users still do not seem satisfied. From the comprehensive evaluation of shuttleless loom, the reliability of the equipment is considered to be only 9%.

Reliability integrates the application of various disciplines such as systems engineering, management engineering, value engineering, and ergonomics. It runs through all aspects of textile machinery from design to manufacturing to sales and service, and involves many aspects such as production, management, and manufacturing. Problems. To improve product reliability, we must not only improve on the general quality management and qualitative concepts, but also perform solid work according to scientific methods and laws. To improve the reliability of looms, it is necessary to pay attention to all aspects, and at the same time it needs to cooperate in many ways. There is no shortcut.

In the “main determinant factor when purchasing looms”, the respondents’ choices focused on “advanced equipment technology” and “reliability of the machine”. “Price” came after these two items. The user's choice once again reminded the domestic looms manufacturing companies that the reliability of the machines could not be ignored. The user's request is not only cheap but also of good quality and high reliability. How to produce such a product is a major issue facing domestic looms manufacturing companies.
