Issuing Time:2020/6/30 8:28:31

Needle punched non-woven fabric (felt, non-woven fabric) is a generation of traditional non-woven fabric (felt, non-woven fabric) production technology, the development has been relatively mature so far. The history of the development of needle punching nonwoven fabrics has been initially formed as early as the late 19th century. It was only in the 1940s that when the United Kingdom made improvements to the old needle punching machines, it laid the foundation for needle punching nonwovens. The industrial production of needle punched non-woven fabrics (felt, non-woven fabrics) began only after the end of World War II. It experienced the commercial development period of the 1950s: the growth period from the 50s to the 60s: the 70s to the 80s The maturity period and the rapid development period from the 1990s to the present.

From the 20th century to the present, acupuncture equipment has been greatly developed. The needle-punching machines produced by Di-lo and Fehrer reflect the level of acupuncture equipment. At present, there are many types of needle punching machines. The needle density of the single needle board of Fehrer's needle punching machine can reach 10,000 pieces/m² and the working width is 16.5m. The typical new technology is the curved needle board structure. ; The needle punching frequency of the German Dmo needle punching machine is up to 3500r/min, the density of the single needle board can be up to 16000 pieces/m2, the classic new technology is the needle beam adopts the ellipse movement track.

According to statistics, during the 10 years from 1995 to 2005, the proportion of needle punched nonwoven fabrics (felt, nonwoven fabrics) in carded nonwoven fabrics has remained at 41% to 43%. In the case of non-woven fabrics of other varieties constantly squeezing out of the market, the proportion remains basically unchanged. Non-woven fabric production statistics and predictions produced by different processing methods. From the statistics, we can see that the needle punched nonwoven fabric still occupies an important position in the nonwoven fabric market.

Our needle-punched nonwovens account for about 22.52%. From 1996 to the present, production has shown a significant upward trend. However, the price has not increased, and the technical content of the products is not too high. The profit margin has deteriorated. According to statistics, the proportion of needle punched non-woven fabrics in non-woven production lines is close to 50%, and its output has reached 24.6% of the total output of non-woven fabrics, second only to spun-bonded non-woven fabrics (felt, non-woven Cloth) production. Needle punched non-woven fabrics are the larger varieties of non-woven fabrics (felt, non-woven fabric).

In recent years, due to the relatively low investment in needle punched non-woven fabrics (felt, non-woven fabrics) and a wide range of uses, only various non-woven fabric equipment manufacturers in Jiangsu Province can sell about 200 production lines a year, and These production lines have an annual starting capacity of over 200,000 tons. It is estimated that there are more than 1,000 acupuncture production lines in the country, and some provinces have dozens of acupuncture production lines in just one county. Statistics on the output of needle punched nonwoven fabrics in China from 1997 to 2006. Currently, leather base fabrics, filter fabrics and automotive interior fabrics are developing faster. Take leather-based fabrics as an example. In the past, only 2-3 companies produced this product. Since 2003, leather base fabrics have developed rapidly. In 2004, there were 22 enterprises and 37 production lines in production and under construction, distributed in Hebei, Shandong, Zhejiang, Jiangsu, Fujian and other provinces, of which at least 11 enterprises Production line has been put into production. In the early stages of product development, more than half of the production lines used imported equipment, such as those produced by Dilo, NSC, and Fehrer. In order to meet the needs of the market, acupuncture equipment manufacturers are also continually stepping up the development of equipment with high performance, and the acupuncture machine is developing in the direction of high speed and continuous. Through the continuous efforts of industry insiders, the manufacturing level of our acupuncture equipment is constantly rising and has begun to enter other markets.
