Chemical fiber machinery and equipment to speed up the new field
With the production of chemical fiber to high-tech development, to meet the special requirements of the chemical fiber machinery is also accelerating the pace of development to the new field. 　  　At present, the main research and development direction of chemical fiber industry is: meet the needs of production and life of the new fiber, high performance fiber, function of fiber, differential fiber, regeneration cellulose fiber and chemical fiber products production needs corresponding machinery and equipment to meet production needs. 　　  In addition, the process and technology of fiber elongation, elongated and puts forward new requirements for chemical mechanical equipment. Polyester spinning using conventional spinning process 3 Dan 5 Dan coarse denier silk, single gram of textile raw materials out of the length of the wire only 2.5 km; such as spun once 5 Dan fine denier filament, single gram of textile raw materials out of the wire lengths up to 6.7 km; if using traditional spinning and reduction of gangue into micro fine denier filament spinning processing, length up to 10 km; the same process with direct spinning up to 33 km; if using mechanical exfoliation composite spinning into superfine denier silk, single grams of raw material, spinning length up to 66 km; island composite spinning super fine denier yarn, single grams of fiber lengths up to 200 kilometers. To meet these new functional fiber and new production technology needs of the technical equipment, is the current development of China's chemical fiber machinery direction.
