Abstract
The solution concerns a mixed polypropylene-polyamide 6 fibre with matrix -fibrils structure, suitable for preparation of ultra fine polyamide fibres intended for production of leather fabric or possibly of filtration and insulation materials. The principle of the solution consists in the fact that the mixed fibre is prepared from a mixture of reactor or degraded type of polypropylene (from 40 to 90 percent by weight), of 10 to 60 percent by weight of polyamide 6 with molecular weight Mn = 10,000 to 30,000 and of 0.5 to 5 percent by weight of inoculated copolymer PP-maleinan hydride. The effect of copolymer results in achievement of high degree of dispersivity of the individual components and in high thermodynamic stability of the mixture. During the production of the fibre a structure with oriented microfibrils of polyamide, which are obtainable after dissolution of polypropylene matrix by xylene tetraline decanine in the form of ultra fine fibres of final length with thickness of 0.3 to 1 μm.
