Air Jet Loom Industry Outlook

Qingdao Steady Machinery Co.,Ltd | Updated: Aug 06, 2015

Loom has been rapid development in the past century, the shuttle loom is gradually being substituted with non-woven fabrics. Non-woven fabrics in nearly 70 years of research and development has formed a gripper loom, jet loom, Rapier three pillars of the situation, is toward high-speed, intelligent, automated, reliable and multi-direction.


1 non-woven fabrics and features the world's level


1.1 projectile weaving machine is the first to be recognized on the non-woven fabrics industry in versatility, productivity and the extent technically sound people have reached a very satisfactory level. Undoubtedly the most representative of the manufacturer SulzerTextile company, its latest product P7300 projectile weaving machine maximum speed of 470r / min, the maximum insertion rate of 1400m / min, reed width reaches 5.4m, 4-color weft, weaving road products to wide industrial fabrics, as well as complex jacquard patterns and other fabrics.


1.2 jet loom weaving is the highest production rate, but relatively narrow water jet loom reed width, usually no more than 2m, maximum speed up to 1600r / min, the maximum insertion rate of 2500m / min or more. The air jet loom with the progress of the development of science, technology, reed width has exceeded the rapier, the weft up to 8 colors.


Which TSUDAKOMA company ZAX air jet loom maximum speed up to 1800r / min, the maximum insertion rate of more than 3200m / min. Jet loom relatively narrow variety adaptability, the most suitable for the production of standard fabrics.


In addition, Italy Somet company MACH3 double width vertical loom weft insertion rate of 4500m / min, while the Swiss SulzerTextile the M8300 multi-shed loom insertion rate peaked 6000m / min, both are used jet weft insertion loom .


1.3 rapier started late, but the fastest growing, is currently the most widely used non-woven fabrics.


Rapier's maximum speed in excess of the above 700r / min, which Vamatex's Leonardo rapier maximum speed reached 830r / min, weft insertion rate of 1500m / min, over a gripper loom reed width reach 318m and wider weft up to 12 colors. Rapier wide variety adaptability, cotton, wool, silk, linen can weave, especially woven fabric suit has its unique advantages.


In addition, the French company Proton ICBT rapier, Germany's Dornier HTV rapier has a higher level. Although the weft insertion rate is not high, but stable performance, long life, good physical quality weaving. Use a central positive weft handover, able to adapt to all kinds of weft.


Most of the above types of non-woven fabrics using 32-bit microcomputer control, operation and display screen loom motion parameters variable, weft density change program settings, can be equipped with electronic delivery, electronic coiling, electronic weft, electronic dobby, electronic Jacquard and fast product changeover systems and other devices.


2 Status of weaving technology


With the rapid development of national economy, high-grade novel textile fabrics in short supply, China's exports of clothing fabrics 50% to 60% also rely on imports, which lies in the quality of textile fabrics and low grade,


Varieties can not meet the requirements of garment development. After China's accession to WTO, textile, garment export share will expand, which requires our country in fabric, fabric and other aspects of development and production of some of the more high-count, high-density, light heavy and other high-grade varieties, take advantage of non-woven fabrics, production at home and abroad market demand for products.


Shuttleless looms from the 1970s began to mature, advanced countries to replace the shuttle loom. Non-woven fabrics of the development and introduction of technology has experienced nearly 20 years of hard history, has now about 20 companies producing various types, various grades of non-woven fabrics. Our high-end looms with foreign advanced shuttleless looms compared to the overall level of technology, variety adaptability, operating efficiency, stability and


Reliability, there is still a wide gap. So in recent years, China's annual imports of non-woven fabrics ten thousand units, exceeding the total amount of non-woven fabrics of domestic, import looms foreign exchange accounted for about 20% of imports of textile machinery. At present, China's proportion of shuttleless looms is still very low, only 10%, the proportion of shuttleless cloth is only 20%. According to the state of the textile industry structure adjustment and upgrading of enterprises requirements, the proportion of shuttleless cloth in the "fifth" period will be doubled, up to about 40%, which gives the production and development of China's non-woven fabrics provide the space and opportunities.


Development Trend 3 of shuttleless looms


China's existing non-woven fabrics for the middle and low level 2/3, only ordinary woven fabric, and a third of high-grade imported looms half shuttleless looms. How to use domestically produced high-grade non-woven fabrics to replace imported products, the so-called "middle jacking" is placed in front of the loom manufacturer's problem. China is the largest producer of textiles, a large high-grade non-woven fabrics of the market, a conservative estimate of a million units of annual demand. We should seize the opportunity to broaden the market, from the following efforts to develop new products.


(1) continuously improve the technological content and technology of non-woven fabrics, to high-speed, intelligent, automated direction. Promote the use of electronic technology, such as electronic let-off, electronic coiling, electronic weft, electronic dobby and


Jacquard, and electronic delivery selvedge, cutting edge electronic technology, to simplify the organization, improve speed.


(2) efforts to expand loom technology functions to adapt to changing market requirements for textiles, non-woven fabrics can not only make the weaving of cotton, wool, silk, linen and other textiles, but also woven geotextile, environmental protection, agriculture, water and other areas of industrial cloth.


(3) to improve product quality and machine reliability, stability, so that we develop and produce non-woven fabrics not only in terms of performance to meet the requirements of various weaving process, but also to maintain good performance for a long time, improve shuttleless The average time between failures loom.


(4) through the introduction of technology to shorten the gap between the non-woven machine technology with the international advanced level, to understand the development trend of the world's non-woven fabrics and non-woven fabrics to master advanced manufacturing technology. Modern weaving technology will be the main non-woven fabrics, from nearly 10 years of non-woven machine development trend, the next gripper loom, jet loom, Rapier a situation that will change. Evolving rapier will be close to or exceed gripper loom in the variety adaptability, width, etc., so as to gradually replace the projectile weaving machines. Water Jet Loom has its advantages in the production of narrow, hydrophobic fabrics. Jet looms will be more widely adaptable varieties, its technology is constantly updated and mature, will become the mainstream of shuttleless looms. Therefore, the future prospects of the most broad-jet looms.
