世界上纺粘无纺布技术主要有德国莱芬的莱科菲尔技术、意大利的STP技术、日本的神户制钢技术等。当前状况，尤其以莱芬技术成为世界上的主流技术。目前已经发展到第四代技术。特点是采用负压超高速气流牵伸，纤维能够被拉伸到1旦尼尔左右。国内已经有很多企业进行了仿制，由于其核心技术有许多前沿性的问题尚未解决或掌握，国内设备制造企业要想达到莱芬技术水平尚待时日。
The main spunbonded nonwovens technologies in the world are Lekofir technology in Lefen, Germany, STP technology in Italy and Kobe steel technology in Japan. Current situation, especially the Levin technology has become the mainstream technology in the world. At present, it has developed to the dakeluo.89ix.comdiaosu.71ix.comjinggaiz.89ix.comwusuanna.89ix.com jinggaif.89ix.comliuliangji.37ix.com.cnfourth generation technology. Characterized by the use of negative pressure and ultra-high speed air draft, the fiber can be stretched to about 1 Daniel. Many domestic enterprises have imitated it. Because many frontier problems of its core technology have not been solved or mastered, it will take some time for domestic equipment manufacturers to reach Levin's technical level.
