Abstract:
A process for preadherizing a polyester filament to improve adhesion of rubber material with the filament, said process comprising the steps of:a) supplying a first soluble ingredient to a running or moving drawn polyester filament at a first location so as to apply the first soluble ingredient to the drawn polyester filament at said first location; andb) supplying a second soluble ingredient to the running or moving drawn polyester filament at a second location spaced a predetermined distance downstream in a filament running direction from said first location, so as to mix the second soluble ingredient with the first soluble ingredient in order to thus form the preadherizing agent on the drawn polyester filament;wherein said first soluble ingredient comprises a polyepoxide and said second soluble ingredient comprises a tertiary amine.
