发明名称 PARTICLES-CONTAINING FIBERS
摘要 textile industry. SUBSTANCE: fibers are manufactured from polyolefin or polyolefin copolymer and contain 0.1-20 wt % of inorganic particles, and have Moose hardness less than 5. At least 90 wt % of inorganic particles have particle size less than 10 microns. Fibers may be formed into fabric and glued on calendar roll at rate of at least 100 m/min in "gluing" window, which is 10% wider than "gluing" window for gluing of nonwoven fabric manufactured from fibers free of inorganic particles. Nonwoven fabric has basic weight of 20 g/cm, average value of static electric charge measured at point 3 cm above fabric roll at least 20% below average value measured above roll of nonwoven fabric manufactured from fibers free of inorganic particles. Nonwoven material is manufactured by forming fibrous fabric from staple fibers and gluing fibrous fabric lengths or by forming fabric lengths from yarn and gluing them. Nonwoven fabric has increased gluing index. EFFECT: increased efficiency by retaining physico-mechanical properties of materials. 32 cl, 2 dwg, 5 tbl, 9 ex
