Description

B 2349B9

The invention relates to a process for the preparation of colored and filled polyolefin fibers or other polymeric products.

The dyeing of polyolefin fibers and other polymer products is currently carried out predominantly by the mass use of color pigments. Part of the spinning of these fibers is also dyed by surface bonding, by acidic, alkaline, respectively complex colors.

The surface-dyeing of the polyolefin fibers into the polymer adds the substances called modifiers. Fiber modifying modifier is a chemical that produces a "dyeing" center in the fiber with the function of binding the dye molecules, the subject being dispersed in the base polymer, but not substantially altering its molecular structure. Currently, two modifier groups are developing for polyolefin fiber surface dyeing. They are high and low-moiety compounds.

The high molecular weight modifier for this purpose must be characterized by certain physical and chemical properties. Between those guys. these include, for example, melt-free meltability, polymer processing heat tolerances, polymer compatibility, fiber diffusability, UV radiation resistance, dye molecule binding, non-stickness, and more.

SUMMARY OF THE PREFERRED EMBODIMENTS The present invention relates to basic type materials. These include the aliphatic, alicyclic, and heterocyclic amino radicals, as well as other basic groups. From the structural or the nucleus, they can occur directly in the chain modifier, or, at the end of the chain modifier, can be attached as a side chain group. With the alkalinity of the step modifier, the colorability of the polyolefin fiber or other polymeric product is acidic. Also, with the alkalinity of the modifier, the color stability of the polymeric products - fibers in detergents - increases.

In the function of modifiers for dyeing polymeric products, high molecular weight species of the following types can be used: - Styrene- (2-methyl-5-vinylpyridine-Polyethyleneimine copolymer (fr. Pat. No. 1,446,285) - Copolymer of ε- caprolactam, hexamethylenedipamide, epichlorohydrin, lauryl-amine - Piperazine-based copolymers, its derivatives and dicarboxylic acids, - Triazole ring polymers - Polyamides (US Pat. No. 18,049) - Modified polyamides (U.S. Pat. - Polymer blends based on 2-laurylamino-triazine-hexamethylene polymers and octadecyl acrylate-glycidyl acrylate copolymers (Japanese Pat. No. 4,527,581) - Polymer blends based on 2,6-dihydroxy-4-alkylamino-triazine-hexamethylenediamine Polymers and Ethyl Ethyl Acrylate Copolymers (Japanese Pat. No. 4,527,864) - Polyamine Modified Ethylene-Maleic Hydride Copolymer (Fr. 2 123 904) - Ethylene-N, N-Dimethylamino-Ethyl Copolymer acrylic t (U.S. Pat. 3,395,198) and others.

The modifiers mentioned can be used as additive to the polymer with the surface dyeing of fibers and other polymeric products using acidic materials. This is one of the variants of the surface, dyeing of polypropylene fibers at present.

The principle of the preparation of colored polyolefin fibers and other products of polyolefins and olefin copolymers according to the invention consists in the use of a plastic modifier in an amount of 1 to 20% by weight, prepared from a basic polymeric substance and acidic by color-melting at temperatures of 110 ° C. up to 250 ° C and subsequent refinement of the color modifier and polyolefin is prepared by extruding a fiber or other article at a temperature of from 230 to 300 ° C.

By using a color modifier in the polymer, the dyeing has the character of dyeing in the mass, analogously to the dyeing of synthetic fibers and other polymeric products.

The high molecular weight modifier, alkaline type, is stained with acidic dyes by spores-bptn: "...". L, -i '-illΔϋίΑΛ Aki ia

va ^ goni / ;. count; ' 1, which (with a ductile skin meacanator) is used. This results in a higher color fastness to the fiber during washing.

If the color modifier in the polymer system is dispersed (assuming some degree of compatibility of the components of the system and the use of a suitable dispersant), homogeneous dyeing of the fibers or other polymeric article with an adjustable color shade occurs. This dyeing method then provides a higher coloring effect compared to a conventional surface dye, for example polypropylene fiber.

The choice of colors for the preparation of a color modifier is based on their thermal stability up to 300 ° C. eaefccs 234969 3

In the preparation of the mold modifier, the following steps are carried out: - The modifier is in the form of granules, a dye is added to it (a recommended disperser) and the mixture is melted in a kneading device. The extrusion technique yields a crop that is cut. - The powder modifier is mixed with the dye (additional ingredients may be added). The mixture is melted and the granulate is prepared as above. - The paste modifier is mixed with the dye and used as a color paste. The modifier, the coloring and the powdered polymers are mixed, resubmitted, and a granulated modifier concentrate is prepared. - The modifier is colored from the colored surface.

The dried color modifier (granulate, powder) and other additives or fillers are added to the granulated polymer in the amount of desired color shade and the mixture is spun by the extruder technique according to the processing parameters of the polymer.

The dried color modifier, the applicator additives melt together, the mixed melt dispenses differently into the melt of the base polymer prepared by the second extruder and the fiber is prepared from the homogenized mixture. The colored fiber obtained is owed, shaped, fixed, rocked, or overcoated. For the preparation of the staple fiber, the fiber is extracted, stabilized, curled and cut to the desired length. Thus obtained fiber or other polymeric products have the standard properties of commercial product types. The advantages of the process according to the invention are as follows: - The economically more advantageous availability of components of a color high molecular weight compound compared to pigments in the dyeing of articles in bulk. - Use a wider variety of available acid colors. - For roughly the same economic costs, a higher saturation and brilliance of the dyeing is achieved. The dyeing procedure is applicable to the production of polyolefin fibers on devices used to color these fibers with pigments. - The disappearance of the migration ability of the high molecular weight compound (color modifier), ie the increased color fastness diffusion compared to the use of low molecular weight modifiers in surface-colored fibers. The economic advantageousness and availability of a color modifier (color high-molecular compound) of the present invention compared to the use of a fiber modifier and its subsequent dyeing.
