Analysis Of Development Trend Of New Looms In China

< p > 1 < a href= "http://www.91se91.com/news/" > shuttleless loom < /a > characteristics and world level < /p >

< p > 1.1 looms are the earliest shuttleless looms that have been recognized by industry. They have reached a satisfactory level in terms of usability, productivity and technical perfection.

The most representative manufacturer is the Sulzer Textile company. Its latest product, P7300 piece loom, has a maximum speed of 470 r/ min, with a maximum insertion rate of 1400 m/ min, a reed width of 5.4 m, and 4 yarn of weft yarn. It can weave main road products into wide industrial fabrics and complex jacquard patterns.

< /p >

< p > 1.2 jet loom is the loom with the highest production rate, but the reed width of the water jet loom is relatively narrow, generally not exceeding 2 m, the maximum speed can reach 1600r/ min, and the maximum insertion rate is above 2500 m/ min.

With the development of science and technology, the reed width has exceeded the rapier loom, and the weft yarn can reach 8 colors.

Table 1 is the air-jet loom product of some companies.

< /p >

< p > in which TSUDA KOMA's ZAX air-jet loom can reach a maximum speed of 1800 r/ min, and the highest insertion rate exceeds 3200m/ min.

The adaptability of jet looms is relatively narrow, which is most suitable for producing standard fabrics.

< /p >

< p > in addition, the weft insertion rate of the MACH3 double vertical loom of Italy Somet company is 4500 m/ min, while the weft insertion rate of the M8300 multi shuttle loom of Switzerland Sulzer Textile reaches the highest value 6000m/ min, and the two looms are air-jet weft insertion.

< /p >

< p > 1.3 < a href= "http://www.91se91.com/news/index_c.asp" > rapier loom < /a > started late, but developed fastest. It is currently the most widely used shuttleless loom.

Table 2 is a rapier loom product for some companies.

< /p >

The maximum speed of the rapier loom above P exceeds 700 r/ min, of which Vamatex's Leonardo rapier loom reaches a maximum speed of 830 r/ min, and the insertion rate reaches 1500 m/ min, which exceeds the loom loom. The reed width reaches 318 m and wider, and the weft yarn reaches 12 colors.

Rapier looms have wide adaptability, and cotton, wool, silk and linen can be woven, especially the weaving of fancy fabric has its unique advantages.

< /p >

< p > in addition, the Proton rapier loom of ICB T of France, the HTV rapier loom of German Dornier company has a higher level.

Although the weft insertion rate is not very high, the whole machine has stable performance, long service life and good quality of weaving.

The central positive weft pfer can be applied to all kinds of weft yarns.

< /p >

< p > the above types of shuttleless looms are mostly controlled by 32 bit microcomputer control, screen operation and display of motion parameters of looms, weft density change program settings, and can be equipped with electronic let off, electronic take-up, electronic weft selection, electronic dobby, electronic jacquard and rapid product pformation system.

< p > 2 China's weaving technology status quo < /p >

< p > with the rapid development of the national economy, the top grade novelty < a target= "_blank" href= "http://www.91se91.com/" > textile < /a > fabric is in short supply. China's exports are a target= "_blank" href= "_blank" > clothing < < 50% > 60% to rely on imports, which lies in the low quality and low grade of our textile fabrics.

< p > variety can not meet the requirements of garment development.

After China's entry into the WTO, "a href=" "http://www.91se91.com" > textile < /a >, the export share of clothing will be expanded. This requires our country to develop and produce high grade, high density, light weight and other high-grade varieties in grey fabric and fabric, and make use of the advantages of shuttleless loom to produce domestic and foreign market demand products.

< /p >

< p > Table 3 is a part of high-grade shuttleless loom product designed and manufactured by our country.

< /p >

< p > shuttleless looms have been mature since 70s, and advanced countries are replacing shuttle looms.

The development and technology introduction of shuttleless looms in China has gone through nearly 20 years of hard times. Now, about 20 enterprises have produced shuttleless looms of various types and grades. (see Table 3).

Compared with the advanced shuttleless looms abroad, the high-grade looms in our country are at the technical level, variety adaptability, operation efficiency, stability and < /p >.

There is still a big gap between < p > reliability.

Therefore, in recent years, China has imported nearly 10000 sets of shuttleless looms per year, exceeding the total volume of homemade shuttleless looms, and accounts for about 20% of imported textile machinery.

At present, the ratio of shuttleless looms in our country is very low, only 10%, and the proportion of no woven fabrics is only 20%.

According to the requirements of the state on the structural adjustment and upgrading of the textile industry, the proportion of the shuttleless cloth will increase by about 40% during the "fifteen" period, which will provide space and opportunity for the production and development of shuttleless looms in China.

< p > 3 the development trend of shuttleless looms in China < /p >

< p > China's existing shuttleless loom 2/ 3 is medium to low grade, and can only knit ordinary fabrics, while half of 1/ 3's high-grade looms are imported shuttleless looms.

How to replace imported products with homemade high-grade shuttleless looms, the so-called "top production", is a problem before looms manufacturer.

China is a large country of textile production, and the market of high-grade shuttleless looms is very large. It is estimated that there will be ten thousand demand per year.

We should seize the opportunity, widen the market and strive to develop new products from the following aspects.

< /p >

< p > (1) continuously improve the technical content and technical level of shuttleless looms, and develop in the direction of high speed, intelligence and automation.

Promote the application of electronic technology, such as electronic let off, electronic coiling, electronic weft selection, electronic dobby and < /p >.

< p > jacquard, and electronic let off, edge trimming, edge cutting technology to simplify the organization and speed up.

< /p >

< p > (2) striving to expand the technological functions of looms so as to meet the requirements of market development for textile changes so that shuttleless looms can not only weave cotton, wool, silk, linen and other textiles, but also make industrial fabrics for geotechnical, environmental protection, agriculture, water conservancy and other fields.

< /p >

< p > (3) improve product quality and reliability and stability of the whole machine, so that the shuttleless loom we develop and produce can not only meet the requirements of various weaving processes, but also maintain good performance for a long time and improve the average malfunction time of shuttleless looms.

< /p >

< p > (4) by introducing technology, we can shorten the gap between the shuttleless loom technology and the international advanced level, and understand the development trend of the world shuttleless looms and master the technology of making advanced shuttleless looms.

The modern weaving technology will be mainly based on shuttleless looms. From the development trend of shuttleless looms in the past 10 years, the situation of three pillars of loom looms, jet looms and rapier looms will change in the future.

The continuous development of rapier looms will approach or surpass loom loom in variety adaptability and width, thus replacing loom loom gradually.

Water jet looms have advantages in producing narrow and hydrophobic fabrics.

The adaptability of air-jet looms will become wider and wider, and its technology will be constantly updated and matured, which will become the mainstream of shuttleless looms.

Therefore, the future development of air-jet looms is the most promising.
