FZ/T93061--2003
Nonwoven fabric laying machine is an important unit machine in the nonwoven fabric production combined machine. Since this machine can be matched with a variety of nonwoven fabric production combined machines, it cannot be used as a part of a certain combined machine standard when formulating standards, but needs to formulate product standards separately. This standard is proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the National Textile Machinery and Accessories Standardization Technical Committee. The drafting units of this standard are: Shanghai Textile Machinery Research Institute, Changshu Feilong Machinery Co., Ltd., Taicang Shuangfeng Nonwoven Fabric Equipment Factory, Yizheng Hairun Textile Machinery Co., Ltd. The main drafters of this standard are: Shi Yaoxun, Lu Zhongbao, Han Xuelong, Fan Zhen, Wang Zhiguang, and Lu Jianguo. 1
