摘要:
The present invention relates to a process for preparing synthetic hair fiber comprising halogen-containing synthetic fiber, in which synthetic hair fiber can be evenly dyed at a low temperature in a short period, maintaining excellent fastness, without abnormal shrinking (frizzing) and embrittlement of the fiber due to swelling. The object is attained by dipping the synthetic hair fiber bundle in a solution containing a dye, a carrier (accelerating agent) and a solvent for halogen-containing fiber, and then dyeing at 60° to 90°C.

摘要:
An optical pattern can be placed within a hydrophobic polymer article, for example a polyester film, by printing disperse dyestuff directly onto the surface of the article followed by heat treatment to cause the dyestuff to diffuse into the surface of the article without use of any swelling agent. The pattern may be a visible pattern, and is highly resistant to scratching, scuffing and migration, bleeding or blooming. The dyestuff is preferably applied to the article together with a polymeric thickening agent. The dyestuff may be coated onto the article from a dispersion in a volatile liquid such as water or a mixture of water with a low-boiling organic solvent.
摘要:
A low-temperature dyeing additive for protein fiber products, which has a pH value of 3.5 to 9.5 and contains 0.025-40 g, per liter of water, of at least one solvent which has a donor number of 24 to 50 and an acceptor number of 10 to 24 in the presence or absence of a surfactant and is freely miscible with water. If necessary, the additive further contains 0.025-4.0 g of tributoxyethyl phosphate per liter of water and/or 0.05-40 g of at least one kind of anion having an enthalpy of hydration (-ΔH KJ.mol -1) of 200-290 per liter of water. This additive serves to relax the higher-order structures of the protein fibers before or after dyeing to thereby swell the fibers, thus rendering the fibers readily dyeable without detriment to the properties thereof.
摘要:
A substantially non-aqueous process for the dyeing of a dyeable material at an elevated temperature comprises contacting a dyeable material with a dye composition at an elevated temperature in a non-reactive environment such as that provided by a fluorocarbon. 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.
摘要:
A non-aqueous process for dyeing a shaped article at an elevated temperature comprises causing a thin continuous film of a dye composition to flow over the surfaces of the shaped article at an elevated temperature. The dye composition temperature and the time of contact between the dye composition and the shaped article are sufficient to effectuate the dyeing of the shaped article. The dye composition comprises a substantially non-aqueous solvent, a dyestuff, and one or more additives, if needed.
