Изобретение отиоситс к способу получени окрашенных пленок, в частности полиэтнлентерефталатных .The invention of Otosit to a method for producing colored films, in particular polyethylene terephthalate.
Известен способ получени окрашенных пленок из полиэтилентерефталата обработки их в водной дисперсии красител , промывки и сушки.A method of obtaining colored films of polyethylene terephthalate by treating them in an aqueous dispersion of a dye, washing and drying is known.
Предложено с целью получени интенсивно окрашенных пленок, снижени расхода красител и ускорени процесса крашени на пленку перед крашением наносить слой полиэтилеитерефталатной смолы со степенью полимеризации 70-100 с последующей сунь кой и краиюнием на обычном оборудовании при 90° С.It was proposed to apply a film of polyethylene terephthalate resin with a degree of polymerization of 70-100 with subsequent polymerization and drying in conventional equipment at 90 ° C in order to obtain intensely colored films, reduce the consumption of dye and speed up the dyeing process.
Иример. На двухвальной плюсовке нри заправке нленки в «жало валов при 20- 25° С на нленку нанос т композицию, содержащую терефталатную смолу ТФ-60, растворенную в органическом растворителе, например хлористом метилене. Высушенную ирн 70-75° С пленку окрашивают в красильнойIrimer. On a two-shaft padding, when filling nlenki in a sting of shafts at 20-25 ° C, a composition containing terephthalate resin TF-60, dissolved in an organic solvent, for example, methylene chloride, is applied to the foil. The dried irn 70-75 ° C film is painted in the dye
ванне в течение 3 мин при 90° С, затем промывают и сушат при 100-120° С.bath for 3 min at 90 ° C, then washed and dried at 100-120 ° C.
