POROESE, SCHWER ENTFLAMMBARE SYNTHETISCHE ACRYLFASERN UND VERFAHREN ZU DEREN HERSTELLUNG |
摘要 |
Porous flame retarded acrylic synthetic fibers consisting of cellulose acetate and a modacrylic copolymer containing vinyl chloride and/or vinylidene chloride are produced by spinning an organic solvent solution of a polymer consisting of cellulose acetate and the above described modacrylic copolymer into a coagulation bath, primarily drawing the spun fibers at a draw ratio of 2.5 DIFFERENCE 8.0, drying the water swelled fibers at 100 DEG DIFFERENCE 180 DEG C. to a water content of no greater than 1.0% by weight and secondarily drawing the dried fibers under wet heat at a draw ratio of no greater than 3 times. |
