Differential dyeing cotton. 1. Preparation and evaluation of differential dyeing cotton yarn was written by Clipson, Jacqueline A.;Roberts, George A. F.. And the article was included in Journal of the Society of Dyers and Colourists in 1989.Product Details of 2272-40-4 The following contents are mentioned in the article:
The synthesis and evaluation of a series of colorless reactive cationic compounds based on the s-triazine nucleus, together with an anionic analog, and the results of a preliminary investigation of their effects on the subsequent dyeing behavior of cotton yarns pretreated with these reagents are reported. Yarns pretreated with cationic reagents showed better uptake of acid and direct dyes than did untreated yarn, and since the degree of differential uptake depended on the level of pretreatment, which could be readily controlled, fabrics exhibiting a variety of tone-on-tone effects were produced. Treatment with an anionic reagent gave cotton dyeable with basic dyes. Combinations of anionic- and cationic-treated yarns were cross dyed in a single-bath 1-step process with very little cross staining. Pretreated cotton was converted to rayon or cellulose acetate fibers with retention of the modified dyeing properties, thus providing roots to differential-dyeing rayon and acetate fibers. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Product Details of 2272-40-4).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Product Details of 2272-40-4
