Definitions

  • the present invention relates to the improvement of the tinctorial characetristics of textile fibres, films, tapes, shaped articles and the like, obtained by extrusion of mixtures of polyolefins consisting essentially of isotactic macromolecules and basic substances acting as tinctorial modifiers, with or without other materials such as stabilizers, solid dispersing agents, opacifiers, dyes and the like.
  • the present invention relates to the treatment of fibres and the like with monoand/or bifunctional derivatives obtained by the reaction of epichlorohydrin with long chain aliphatic amines or with aromatic or heterocyclic amines in order to improve dye receptivity, and to obtain a good color fastness and improved hand characteristics in the resulting textile fibres.
  • Textile fibres obtained from mixtures of synthetic polymers and tinctorial modifiers of a basic nature have a good receptivity to dyes, but are disadvantageous in that the basic compounds mixed with the olefin polymer is somewhat water soluble. Moreover, the tinctorial modifier shows a tendency to migrate out from the fibres, thus causing a greasiness in the manufactured articles ultimately obtained.
  • the treatment of the present invention makes it possible to reduce the amount of tinctorial modifiers incorporated in the 'polyolefin, since the treatment with the nitrogen compounds according to the invention makes it possible to introduce into the fibre that amount of nitrogen required to increase the dyeability of the polyolefin with acid dyes.
  • Suitable compounds which can be used according to the present invention include N-mono-glycidyl derivatives and N-di-glycidyl derivatives of n-dodecylamine and of n-octadecylamine, N-monoand di-chlorohydroxypropyl derivatives of n-dodecylamine and octadecylamine, N- glycidylpiperazine, N,N' -diglycidylpiperazine, N-chlorohydroxypropylpiperazine, and N,N'-di(chlorohydroxypropyl)piperazine.
  • N-monoand diglycidyl derivatives of primary C C aliphatic amines and of piperazine as well as the mono-chlorohydroxypropyl and di- (chlorohydroxypropyl) derivatives are applied from solutions or dispersions in water or in an organic solvent or in the anhydrous state.
  • the application of the foregoing compounds can be carried out before or after stretching of the fibres.
  • the duration of the treatment may vary from a few seconds to 3 hours, at a temperature of from about room temperature to C. below the softening point of the base polymer.
  • Textile fibres which are to be subjected to the treatment of the present invention consist essentially of at least of a polyolefin, more particularly polypropylene consisting essentially of isotactic macromolecules and obtained by stereospecific catalysis of propylene, and from about 1 to 25% of a tinctorial modifier.
  • the tinctorial modifiers (basic nitrogen compounds) used for preparing dyeable textile fibres may be amines or imines of the polyalkylenimine type, or may comprise a nitrogen polycondensate of epichlorohydrin, having a specific viscosity, determined at 25 C. in 1% isopropanol solutions, comprised between 0.1 and 0.7.
  • the mixtures, after granulation or simple sintering, are extruded in a melt spinning device using spinnerets having a length/ diameter ratio greater than 1.
  • the granulation and spinning are carried out by operating in the absence of oxygen, and preferably under an inert gas (e.g., nitrogen).
  • an inert gas e.g., nitrogen
  • Spinning of the mixtures can conveniently be carried out in the presence of a small amount of a solid dispersing agent which facilitates the homogeneous dispersion of the basic nitrogen compound in the molten polymer mass.
  • the dispersing agent is desirably one of the following materials: octyl' and/or stearyl alcohols, stearic acid, benzoin, furoin, vinyl stearate, mono-, diand tri-stearic esters of glycerol, monoethanolamine stearate, stearamide, N-diethanol-lauramide, C C aliphatic amines, condensation products of ethylene oxide with amines of phenols, polystearamide, polyacrylic acid, polystyrene, styrene copolymers, terpene polymers, and the like.
  • stabilizers, opacifiers, and organic or inorganic pigments can, if desired, be added to the polyolefin in addition to the foregoing nitrogen compounds.
  • the fibres, after spinning, are subjected to a stretching process, with stretching ratios of from about 1:2 to 1:10, at temperatures of from about to C., in stretching devices heated with hot air or steam or with a similar fluid, or provided with a heating plate.
  • the fibres thus obtained can be subjected to a dimensional stabilization treatment under conditions of free or hindered shrinking from about 80160 C.
  • the fibres obtained by extrusion of the mixtures of the present invention can be monoor plurifilaments and can be used for preparing bulk yarns or bulk staple fibres.
  • the fibres subjected to the treatment with the aforementioned monoand diglyciciyl derivatives and/or monoand di-(chlorohydroxypropyl) derivatives exhibit a remarkable receptivity for acid dyes, metallized dyes, and disperse dyes.
  • Such fibres also exhibit a good afiinity for basic and vat dyes, exhibit superior hand characteristics, and show particularly solid colors.
  • the fibres obtained according to the present invention show an increased stability with respect to light.
  • control dyeing tests Were carried out for 1 hour and half at the boiling point, in baths containing 2.5% of dye by weight of the fibre, with a fibre/bath ratio of 1:40.
  • Dyeing with acid and metallized dyes was carried out in the presence of 3% ammonium acetate (calculated on the fibre weight) and of 1% of a surface-active agent, namely, the condensation product of 620 mols of ethylene oxide with 1 mol of an alkylphenol such as p-tert. octylphenol, nonylphenol and the like.
