Myasnikov S. Development of low-modulus technology of artificial knitted fur coloring and finishing

Object of research - low-modulus technologies of dyeing and finishing of artificial knitted fur. The purpose of research is improvement of consumer properties of artificial knitted fur by development of resource-saving low-modulus technologies of colouring and finishing. It is shown for the first time, that when colouring of polyacrylonitrile fibre is carried out by spraying method, the dyeing process goes on in more optimum thermodynamic and kinetic conditions. It is determined, that when colouring of polyacrylonitrile fibre is done by the method of dyestuff spraying, we can provide even dyeing without complex step temperature-time schemes. It is shown, that applying of dye by spraying method allows to use more widely mixes of dyes and to combine slow- and fast-exhausted dyes in one dyeing solution, to reduce dependence of dyeing result on affinity of dye to a fibre, to optimize structures of dyeing solutions and to make them more universal in comparison with traditional ways of dyeing.
