(1) Germany Reifenhauser Company The company is the world's largest supplier of spunbond equipment. It has produced about 150 types of PP production lines. China has more than 10 production lines. The biggest feature of the company's equipment is The width of the spinneret is the width of the product, and the drafting is carried out under vacuum. Therefore, the equipment is compact, the structure is simple, the product is evenly meshed, and the energy consumption is low. The main products are PP spunbonded nonwoven fabric, spunbond/meltblown composite. Nonwovens (SMS). According to the company's recent introduction, there is a test production line for PE/PP two-component composite. The shortcomings of the company's products are insufficient drafting, so it cannot produce spunbond and composite of PET and PA. Spunbond products.
(2) Ason Company Ason Company is located in Tennessee, USA, and has been merged by Newmag. It is the manufacturer that introduced the two-component spunbond method to China earlier. The main technician is Beijing Institute of Clothing Technology, China. Lu Fumin, a fellow scholar, uses positive pressure drafting. It is said that the spinning speed can exceed 5000m/min. It can produce single-component and two-component spunbond products of PET, PA, PP and PE. The disadvantage is the external supply. The number of mature production lines is small.
(3) US Nordson Corporation The company is a multinational company. In 1999, it acquired JM Laboratories and entered the spunbonding industry.
