利用激光打孔喷丝板制备新型纤维素纤维

IFSW/ITCF:Laser drilled spinnerets for cellulose fibers with new properties

德国斯图加特大学激光技术研究所(IFSW)和德国邓肯多夫纺织化学与化学纤维研究所(ITCF)的一项联合研究结果表明,将一束明亮的绿色激光穿过4mm厚的不锈钢钢盘,利用高能超短脉冲激光束重复钻入金属表面,可钻出大量喷丝孔。该喷丝孔的直径为30~40μm,远小于头发丝,能用于制备纤维素纤维,即细旦纤维或超细旦纤维。

A stainless steel disc around 4 mm thick,is illuminated by a bright green beam of laser light.With high energy,the ultra-short-pulsed laser beam bores into the surface of the metal repeatedly,until a large number of holes have been made.What is produced at the Institute of Laser Technologies（IFSW）at the University of Stuttgart/Germany is the result of a joint research project together with the Institute of Textile Chemistry and Chemical Fibers（ITCF）in Denkendort/Germany：spinnersts with a diameter of 30-40μm,much finer than a human hair,which are utilized in the production of ultra-fine cellulose fibers,or socalled micr-or supermicrofibers.
