Kokai Tokkyo Koho JP 08325940 A2 10 Dec 1996 Heisei, 6 pp.In this study， 112-03-8 and 61792-35-6 are also used. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: D06M013-463. ICS: D01F006-18; D01F011-06; D06M101-28. APPLICATION: JP 1995-162874 5 Jun 1995. DOCUMENT TYPE: Patent CA Section: 40 (Textiles and Fibers) The fibers are manufd. by addn. of 0.1-1.0% (on fibers) oil compns. contg. 20-95% of 31 quaternary ammonium-based oils R1N+R2R3R4 X- [R1 = C10-18 alkyl, R5CONHR6; R5 = C11-21 alkyl; R6 = C2-5 alkylene; R2 = C1-3 alkyl, (C2H4O)nH; n = 1-10; R3 = C1-3 alkyl, C12-18 alkyl, (C2H4O)mH; m = 1-10; R4 = C1-3 alkyl, PhCH2, hydroxyethyl, hydroxypropyl; X = I, Cl, Br, NO3, MeSO4, EtSO4, OH, (MeO)2P(O)O] and 5-80% of 31 nonionic oils selected from 10--90 propylene oxide (I)-ethylene oxide (II) copolymer [wt.-av. mol. wt. (Mw) 5000-15,000], polyoxyethylene alkyl ethers (d.p. 10-50, C8-18 alkyl or alkenyl), and polyethylene glycol mono- or dialkyl esters (Mw of polyethylene glycol 4000-6000, C11-17 alkyl esters) to acrylic fibers into which crosslinking bonds are introduced by treatment with H2NNH2. Fibers of acrylonitrile-Me acrylate copolymer were crosslinked with hydrazine hydrate and hydrolyzed with aq. 61792-35-6 are also occured in this study. NaOH to give highly moisture-absorbing crosslinked acrylic fibers, which were treated with aq. HNO3, neutralized, and treated with CaCl2 ot give pH-buffering fibers. Then, the fibers were treated with a compn. contg. 50% stearylamidopropyldimethyl(b-hydroxyethyl)ammonium nitrate and 50% I-II () copolymer to give products showing good spinning property and high antibacterial effect after washing 10 times. ..
