Chemical treatments designed to modify the affinity of wool for dyes was written by Bell, V. A.;Lewis, D. M.;Pailthorpe, M. T.. And the article was included in Journal of the Society of Dyers and Colourists in 1984.Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine The following contents are mentioned in the article:
The dyeing properties of wool were modified by treating it with a series of reactive hydrophobic, anionic, and cationic compounds The extent of fixation of these compounds was 10-13 weight% for sulfamic acid, Sandospace R (QNHZSO3Na; Z = arylene, Q = 2,4-dichloro-s-triazin-6-yl) [4156-21-2], MP 1 (2,4-HO(QNH)C6H3CO2Na) [91869-47-5], KP 1 (3-QNHC6H4PO3Na2) [91869-46-4], ANEX (QNHPh) [2272-40-4], and benzoylation, and 6-8 weight% for BNEX (4-QNHC6H4Bu) [90850-60-5], NAPEX (1-C10H7NHQ) [30369-88-1], Sandospace DP [92047-56-8], and Glytac A (glycidyltrimethylammonium chloride) [3033-77-0]. Dyeing properties were examined with a series of anionic, cationic, and reactive dyes. The hydrophobic mechanism of dyeing appeared to predominate over the ionic mechanism, except for those dyes which were highly ionized. The monosulfonated dye C.I. Acid Red 88 was more strongly absorbed by hydrophobic wool (benzoylated or ANEX-treated) and had an improved wash fastness rating on the treated wool. C.I. Reactive Red 116 was effectively resisted by the hydrophobic anionic treatments since these compounds eliminated nucleophilic sites normally available for reaction with reactive dyes. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine
