Definitions
- This invention relates to an improved method for dyeing and printing of polyolefins. Especially the invention relates in improvements of fixation speed of acid dyes on acid dyeable polyolefins. Also, the invention relates to fibers and articles made of these fibres containing this dyeable polyolefin.
- Polyolefins such as polypropylene and polyethylene have excellent physical and mechanical properties and excellent processability.
- the dyeing of polyolefins, especially polypropylene, polyolefin fibers and articles made from the fibers with conventional acid dyes and dyeing technologies has been very difficult because of the hydrophobicity and the lack of sites where hydrogen bonds or electrostatic attraction can operate, it has been very difficult to dye fabricated articles of these polymers.
- crystalline polypropylene fibers are lightweight and strong and they have good heat-retaining properties. These fibers have been expected to have wide applications, but have still limited use because it has not been able to dye them by ordinary dyeing methods.
- a dyeable polyolefin which is obtained by blending 0,1 - 30 % by weight ethylene/aminoalkylacrylatecopolymer.
- ethylene/aminoalkylacrylatecopolymer Preferably it is a copolymer of ethylene and dimethylaminoethylmethacrylate.
- EP 269293 describes a method to incorporate dyesites in polyolefin matrix in order to obtain electrostatic attraction between acid dyestuffs and the polyolefin matrix.
- the corresponding copolymer is a copolymer of ethylene and dialkyl aminoalkylacrylamide.
- This the dyeable composition comprises 100 parts per weight polyolefin, 1-20 parts per weight the above mentioned copolymer and also 0-3 parts per weight at least one alkali metal salt of an organic carboxylic acid having 7-24 carbon atoms.
- modified polyolefins especially polypropylenes
- contain functional groups rendering it dyeable with acid dyes still the polypropylene matrix is very unpolar and therfor hydrophobic. A way to obtain deep enough colours with very long dyeing times is not attractive.
- Acid dyes are polar and water soluble and the dyeing happens from an aqueous solution.
- the combination of polar and unpolar phases is the subject of this invention.
- auxiliaries according to this invention are fatty alcohols or alkyl phenols of polyalkoxylated carboxylic acids of general formula (I): R - O -((CH 2 ) n - O) m - CH 2 - COOH (I) where
- Typical addition levels of the auxiliary (I) are 2-50 g/kg for printing paste, from 0.1-5 % on weight of fabric (owf) for exhaust dyeing and 1-50 g/litre for continuous dyeing applications, in particular with a liquid Pick Up (P.U.) of 100 %.
- the lower addition levels are for light shades, and the higher addition levels are for deep shades.
- This invention further concerns the fibers made from the dyeable polyolefin composition and the articles made from these fibers.
- the dyeable polyolefin composition according to this invention comprises a melt blended mixture of
- the polyolefin composition comprises
- the polyolefins (A) used in this invention are crystalline homopolymers of ⁇ -olefins like polyethylene, polypropylene, polybutene-1, poly-4-methylpentene-1 or various crystalline copolymers of those ⁇ -olefins. Most preferably the polyolefin is crystalline homopolymer or copolymer of propylene.
- the suitable melt index of polyolefins is 0.5 - 800.
- Suitable dialkylaminoalkyl methacrylamide or methacrylate comonomers for ethylene copolymers (B) are for example dimethylaminoethyl methacrylamide or methacryate, dimethylaminopropyl methacrylamide or methacrylate diethylaminoethyl methacrylamide or methacrylate.
- the alkyl groups are C 1 -C 4 alkyl groups, but most preferably the comonomer is dimethylaminopropyl methacrylamide.
- a suitable proportion of the comonomer unit in the ethylene copolymer is 5-60 % by weight, preferably 10-50 % by weight.
- the amount of ethylene copolymer (B) is 1-20 parts per weigth, based on 100 parts per weight polyolefin, preferably 2-10 parts per weight.
- the alkali metal salt of an organic carboxylic acid (C) is e.g. sodium, potassium or lithium salt of organic acids, such as higher fatty acids having 10-24 carbon atoms, aromatic acids or nicotinic acids.
- organic acids such as higher fatty acids having 10-24 carbon atoms, aromatic acids or nicotinic acids.
- Sodium or potassium stearate or benzoate, sodium p-tert-butylbenzoate or sodium nicotinate are preferred.
- the composition can be produced by conventional mixing methods, preferably by melt blending using an extruder or other suitable equipment.
- the dyeable polyolefin composition can be formed into fibers by conventional methods like melt spinning methods, but can also be fabricated into other forms such as films, sheets, tubes and into any extruded shape.
- the anionic dyes such as acid dyes, pre-metallised acid dyes, direct dyes or acid mordant dyes are dissolved in an exhaust dyeing bath, a continuous dyeing liquor, or a printing paste, which is adjusted to a suitable acidic condition by inorganic or organic acids such as acetic, oxalic, formic, citric, benzoic acid etc.
- the fibers or fiber products are then brought into contact with the dye solotion and heat treated at about 100 °C.
- This heat treatment especially when fiber products are dyed or printed, is very critical point in the process and should be made efficiently and with a high speed.
- the auxiliaries according to this invention make the high speed possible.
- the fixation time without the auxiliaries in the printing process is about 3 to 15 minutes, depending on depth of the shade. Light shades fix at 3 minutes, dark shades need 15 minutes for full dyestuff fixation. But according to this invention, the fixation time can be shortened to about 1.5 to 5 minutes depending on the depth of the shade.
- Polypropylene, melt index 18, (produced by Borealis N.V.) and 7 % by weight a copolymer of ethylene and dimethylaminopropyl methacrylamide (EDMAPMA) were melt blended and spun into filaments (1250/65 dtex) and tufted into a carpet.
- the carpets have been printed with a mixture of Colour Index (C.I.) Acid Yellow 216:1, C.I. Acid Red 266 and C.I. Acid Blue 40 to have a dark brown trichromatic colour.
- the printing paste contains a thickener such as a Guar Gum, the dyestuffs and citric acid to ensure the protonation of the acid dyesites in the modified polypropylene.
- the citric acid is added until pH value of 3.0-3.5 is obtained.
- Printing paste 1 contains the above mentioned elements (comparative)
- Printing paste 2 contains on top of above mentioned components 20 g/kg of fixation speed improvement auxiliary (I), where
- the carpets After printing, in order to fix the applied amount of dyestuff, the carpets go into a steamer for 2 minutes. Steaming conditions are 100 °C and relative humidity 50 %. After the fixation in the steamer, the carpets are rinsed in cold water and the colour depth of the fixed dyestuffs is evaluated visually or by means of spectrophotometer.
- the carpet printed with the paste 2 has the double colour depth of the carpet printed with paste 1.
- the same polypropylene composition as in example 1 was melt spun into fibers which were used to make hanks, which have been exhaust dyed with C.I Acid Red 266 to obtain a deep red colour.
- An exhaust dyebath is prepared with a solution of 2 % on weight of fabric (owf) of C.I. Acid Red 266 containing phormic acid to protonate the acid dyesites in the modified polypropylene.
- the pH is adjusted to 3.0-3.5.
- the hanks were put into the exhaust dyebath and heated up until 100 °C and stayed there until dyestuff exhaustion is obtained.
- the dyeing time for full exhaustion with dyebath 2 is 20 minutes and the dyeing time for exhaust dyebath 1 is 45 minutes.
- Example 2 Same dyeable polypropylene composition as in Example 1 was melt spun into multifilaments and tufted into a loop pile carpet.
- the carpets were continuos dyed by liquor application of the baths at P.U. of 250 %. After application, the colours were fixed by means of a steaming treatment (100 °C, 50 % relative humidity).
- the colour depth of the carpet dyed with bath 2 is double the colour depth of the carpet dyed with bath 1.
