Definitions

• the present invention relates to a process for preparing dye-receptive shaped articles such as textile fibers, films, sheets, tapes, etc., from alpha-olefin polymers.
• Processes used for obtaining, for example, textile fibers comprise:
• any suitable continuous or discontinuous apparatus capable of supplying heat may be employed for the sintering step.
• 150% of polycondensate may be mixed with 50-99% of polyolefin.
• the method of the present invention more particularly, 1
• polyolefins and basic nitrogen polycondensates obtained by reacting (in the presence or absence of solvents and condensing agents) (1) epichlorohydrin, (2) one or more primary C C or secondary C C aliphatic amines and then subjecting the condensation product to a further condensation with one or more aliphatic, aromatic or heterocyclic secondary diamines.
• These condensates show generally a softening point under C., an intrinsic viscosity (determined in a 1% isopropanol solution) of 005-05 and a nitrogen content up to 35%.
• the shaped articles such as fibers are then prepared by extruding the granules sintered according to the invention.
• the mixes to be extruded contain polyolefins, from 1 to 25% by weight of the nitrogen polycondensate and, if desired, 0.1 to 5% of a solid dispersing agent for dispersing the nitrogen condensate in the molten mass.
• Suitable solid dispersing agents include: cetyl and stearyl alcohols, stearic acid, benzoin, furoin, vinyl stearate, mono-, dior tristearic esters of glycerol, monoethanolamine stearate, stearic amide, C to C aliphatic amines, condensation products of ethylene oxide with alcohols, amines or phenols, polystearamide, polyacrylic acid, polystyrene, styrene copolymers, terpene polymers, etc.
• the sintering and spinning operations according to the present invention may be conveniently carried out under oxygen-free nitrogen.
• the fibers produced may be in the form of monoor pluro-filaments and can be employed for preparing continuous fibers or staples or for preparing either bulky yarns or staples.
• the monoor plum-filaments prepared according to the present invention can be subjected to treatments for the water-insolubilization of the basic nitrogen compound.
• Particularly useful for this purpose are the treatments with formaldehyde, diisocyanates, diepoxy compounds or various cross-linking agents such as divinyl benzene or the like. These treatments may be carried out either before or after stretching.
• the stretching is preferably executed using ratios between 1:2 and 1:10 at temperatures between 80 and C. in stretching devices heated with hot air, steam or similar fluids.
• the fibers thus obtained can be dyed with acid dyes or with plastosoluble dyes. They also exhibit a good aflinity for basic and vat dyestuffs.
• the sintered granules prepared according to the present invention are also suitable for extrusion into films, tapes and various other shaped articles.
• Stereospecific catalysts such as those disclosed by Natta et a1. or shown in Italina Patent 526,101, are examples of suitable catalysts.
• Shaped articles, especially fibers obtained from polyproylene containing predominant amounts (more than 50%) of isotactic macromolecules are of particular interest.
• the residue of the heptane extraction is an indication of the presence of isotactic macromolecules.
• Example 1 A mix is prepared from:
• the mix is then sintered in a machine for preparing tablets.
• the residence time of the mix in the sintering machine is 1 second, and this device reaches a temperature of 90 C.
• the sintered granules are then spun in a melt spinning device under the following conditions:
• Screw temperature C. 250 Head temperature
• Acid black JVS Acid dye Lanasyn red 2GL Metallized dye. Setacyl yellow 3G Plastosoluble dye. Cibacet scarlet BR Plastosoluble dye. Acetoquinone blue RHO Plastosoluble dye.
• Example 2 A mix is prepared from:
• the mix is then sintered in a device for the preparation of tablets.
• the residence time of the mix in the sinterization device is 1 second and the mix reaches a temperature of 100 C.
• the sintered granules are spun in a melt spinning device under the following conditions:
• Screw temperature C. 260 Head temperature
• C. 265 Spinneret temperature C. 265 Spinneret type
• mm 198 x 0.8 x 16 Maximum pressure, kg./cm. 100
• the fibers thus prepared have a clear color and their residual intrinsic viscosity amounts to of the initial value.
• the fibers after being stretched at 130 C. inthe presence of steam with a stretching ratio of 1:5, exhibit the following serimetric characteristics:
• Acid black IVS Acid dye Lanasyn red 2G1 Metallized dye. Setacyl yellow 3G Plastosoluble dye. Cibacet scarlet BR Plastosoluble dye. Acetoquinone blue Plastosoluble dye.
• Example 3 A mix is prepared from:
• the mixture is then sintered in a device for the preparation of pellets using a residence time in the sintering device of 1 sec.
• the mix is heated to a temperature of 80 C. in this device.
• the centered granules are spun in a melt spinning device under the following conditions:
• Acid black IVS Acid dye Lanasyn red 26L Metallized dye. Setacyl yellow 36 Plastosoluble dye. Cibacet scarlet BR Plastosoluble dye. Acetoquino-ne blue RHO Plastosoluble dye.
• the basic nitrogen polycondensate is prepared by reacting 1 mol of a compound from (a), 1 to 3 mols of epichlorohydrin and 0.1 to 10 mols of a bissecondary diamine from (c).
• the amine of (a) is selected from the group consisting of n-dodecylamine, hexadecylamine, octadecylamine, dioctadecylamine, dioctylamine or salts thereof.
