Stable liq. preparations of water-soluble reactive dyes - in conc. aq. solns. of neutral or weakly acid salts |
摘要 |
<p>The prepns. contain a suspension of >=1 such dyestuff in a conc, aq. soln. of neutral or weakly acid salts or mixts. thereof. Pref. the wt. ratio of dyestuff to salt soln. in the suspension is 1:1 - 1:2. The reactive dyes are suitably of the azo-, anthraquinone- and phthalocyanine series, and include the metallised dyes where appropriate. The prepns. are storage-stable, and are partic. suitable for the continuous dyeing and printing of textiles. They contain high concns. of dyestuffs and re-crystallisation of tfhe dyestuffs does not occur. Health hazards due to dyestuff dust are obviated in the prepn. of these liquids.</p> |
