  • Patent number: 5104416
    Abstract: In the conventional methods for the preparation of printing pastes containing couplable diazonium compounds, liquid bases, sodium nitrite and phosphoric acid are incorporated separately in succession in the thickener or they are each prepared as separate thickeners and then combined with stirring only when they are used. Such measures are relatively complicated and are therefore considered as a disadvantage in practice. If the acids customary for the diazotization are used, there is a further risk that the fixation by steaming of the reactive dyes printed in addition to the diazo components will be impaired.This situation considered problematical by persons skilled in the art can be remedied by using liquid water-based preparations of diazotizable amines which, in addition to the amine, simultaneously contain the amount of acid necessary for its diazotization in the form of, preferably, phosphoric acid.

  • Patent number: 4828571
    Abstract: The present invention provides a non-aqueous process for the dyeing of a dyeable material at an elevated temperature by contacting a dyeable material with a dye composition at an elevated temperature in a non-reactive environment. The dye composition temperature and the time of contact between the dye composition and the dyeable material are sufficient to effectuate the dyeing of the material. The dye composition comprises a substantially non-aqueous solvent and a dyestuff.

  • Patent number: 4814222
    Abstract: The flame-resistant properties of aramid fibers are improved using a swelling agent to introduce a flame retardant into the fiber. The treated fiber has properties of strength approximating the untreated fiber, flame resistance greater than the untreated fiber and is conveniently dyed to an unlimited range of colors with high color yield. An aqueous dimethylsulfoxide solution is used as the swelling agent.

  • Patent number: 4812144
    Abstract: Nylon/cotton blend fabrics containing at least 40% by weight of nylon are rendered flame resistant and durable to multiple launderings in a two step process in which a THP/urea precondensate/ammonia polymer network is formed within the cotton fiber structure then durability is enhanced in a second step 1 which a flame resistant cyclic phosphonate ester and a THP salt plus urea are applied. Durability up to 50 multiple washings and continued flame resistance for these nylon/cotton blend fabrics are reported.
