Process for improving dyeability: Process for improving dyeability. Holfeld, Winfried Thomas; Strohmaier, Alfred John (du Pont de Nemours, E. I., and Co., USA). U.S. US 4030880 21 Jun 1977, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: D06P001-00. NCL: 008015000. APPLICATION: US 75-621089 9 Oct 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Application of dye leveling agents to nylon fibers in a primary spin finish prior to drawing provides fibers having a more uniform dyeability by acid dyes in spite of interim treatments such as heating, crimping, and scouring. Thus, poly(hexamethyleneadipamide) flake was melted and spun into 2450 denier, 128 filament yarn which was finished with compns. contg. 4% dye leveling agent, e.g., Alkanol ND (sodium dodecyldiphenyl oxide disulfonate) [28519-02-0], 16% polyethylene polypropylene glycol lubricant, and 80% water prior to drawing. The yarn was dyed with C.I. Acid Blue 122 and tested for dye depth by a reflecting colorimeter. Application of the leveling agent reduced dye variability caused by the differences in draw ratio. Other suitable leveling agents included condensation products of arom. sulfonic acids, sulfated butyl oleate [142-77-8], and polyethylene glycol tridecyl ether [24938-91-8].

Heat-resistant storage-stabile vinyl chloride resin latex with improved film-forming property: Heat-resistant storage-stabile vinyl chloride resin latex with improved film-forming property. Ito, Sumiatsu; Ito, Katsujiro; Igarashi, Toshio (Sumitomo Chemical Co., Ltd.Some commonly used reagents like 28519-02-0 is used in this experiment., Japan). Japan. JP 51037230 B4 14 Oct 1976 Showa, 5 pp. (Japanese). (Japan). There are some commonly used reagents like 28519-02-0 in this article. CODEN: JAXXAD. CLASS: IC: C08F014-06. APPLICATION: JP 74-811 20 Dec 1973. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) A heat-resistant storage-stable vinyl chloride (I) polymer latex (particle size ￡600?) with improved film-forming properties is prepd. in the presence of a 1-4% (based on I) alkyldiphenyl ether disulfonate as emulsifier. Thus, 1200 parts I was polymd. in H2O at 64° under N in the presence of 1.5% di-Na dodecyl(diphenyl ether)disulfonate (II) [28519-02-0] to give a heat-resistant PVC [9002-86-2] latex (particle size 450?) with storage stability 33 mos. compared with 25 days for a latex (particle size 950?) prepd. in the presence of 0.5% II. ..
