Definitions

• the present invention relates to a process for improving the tinctorial characteristics of fibres obtained from mixtures containing olefin polymers, especially polypropyl ene, and basic nitrogen compounds, such as:
• the present invention can be utilized advantageously in addition to said process for improving hand, at a sequence stage to be selected as desired.
• Fibres of polypropylene consisting essentially of isotactic macromolecules are especially suitable for use in the process of the present invention.
• This object is achieved by a treatment such as by contacting with sulfuric acid.
• the treatment with sulfuric acid according to the present invention can be carried out with or without before or after the stretching of the fibres and at some sequence stage such as, before or after the treatment with monoor diepoxy compounds.
• the treatment can be carried out continuously or batchwise, for times varying from 1 second to 60 minutes, at temperature of between 15 and 100 C.
• Aqueous sulfuric acid solutions having concentrations "Ice varying from 0.01% to 30% by weight, are employed.
• any sulfuric acidtreatment-products such as excess or residual sulfuric acid or such as reaction products, of the sulfuric acid, are removed, e.g., the fibres are washed with water and/ or alkaline substances (alkaline o-r earth-alkaline hydroxides, carbonates or the like).
• the heptane residue percent in the polypropylene of the following specific examples is an indication of the presence of isotactic macromolecules (as defined by Natta et al., for example, in US. Patent No. 2,882,263).
• the polypropylene of the following examples therefore consists essentially of isotactic macromolecules.
• the polyimine condensate was prepared by dissolving 1160 g. of hexamethylene diamine in 1800 cc. water at room temperature while agitating in a 6 litre glass vessel, by heating the solution to 90 C. and by adding to it 897 g. of dichloroethane and a 50% aqueous sodium hydroxide solution (725 g.). When the addition is completed, the reaction is continued at 90 C. for 3 hours, it is then cooled at 20-25 C., an upper solid layer is removed to which 2000 cc. water are added, the mass is heated to 7080 C. and decanted While the Water is removed by distillation. A solid polyimine condensate is obtained.
• the polypropylene-polyimine condensate mix is granulated by extrusion in a screw device at C.
• the granulate is spun under the following conditions:
• filaments are then stretched under steam with a stretching ratio of 1:64 and then crimped.
• the crimped roving is passed into a vessel containing a 5% aqueous sulfuric acid solution maintained at 25 C.
• the speed of the entering roving is regulated so as to allow the filaments a residence time in the sulfuric solution of 5 seconds. From the sulfuric solution the filaments pass into another vessel containing a 10% aqueous sodium bicarbonate solution.
• Staples thus obtained are dyed to intense colors with acid, metallizable, plastosoluble (disperse) and vat dyes.
• the fastness of the colors obtained on the fibres subjected to the contact with sulfuric acid according to the present invention is clearly better than that of the colors obtained on corresponding fibres, by otherwise identical dyeing processes not subjected to this contact with sulfuric acid.
• Example 2 A yarn identical with that of Example 1 is prepared; however, the filaments leaving the spinnerett are not epoxidized.
• the filaments after being stretched under steam with a stretching ratio of 1:6.4, are wetted with a 5% aqueous ethyleneglycoldiglycidylether solution and then treated in autoclave with steam under vacuum (150 mm. Hg) at 105-11'0" C.
• filaments are then passed in a vessel containing a 10% aqueous sulfuric acid solution at 25 C.
• the speed of the entering roving is regulated so as to allow the filaments a residence time in the sulfuric solution of 2 seconds.
• the fibres From the sulfuric solution the fibres pass into a vessel containing a 10% aqueous sodium bicarbonate solution. They are then cut and dried. Staples thus obtained are dyed intensely with acid, metallizable, plastosoluble and vat dyes.
• the fastness of the colors obtained on the fibres subjected to the contact with sulfuric acid according to the invention, especially the fastness to washing, is better than that of the colors obtained on correspondingly dyed fibres not subjected to this contact with the sulfuric acid.
• the mix is granulated at 200-210 C. and the granulate is spun under the following conditions:
• the staple thus obtained is contacted for 10 minutes at the boiling point with a 5% aqueous sulfuric acid solution with a fibre/ bath ratio of 1 :20.
• the fibres obtained quickly exhaust the bath and the colors obtained have a fastness, particularly to washing, clearly better than that of the colors obtained on correspondingly dyed fibres not subjected to a treatment with sulfuric acid.
