Fremgangsmåte for kontrastfarving av fottøy. Procedure for contrast dyeing of footwear.
Den foreliggende oppfinnelse vedrorer en fremgangsmåte for kontrastfarving av fottoy fremstilt av mykgjort homo- eller kopolymerisert PVC, basert på at farvestoffet ved migrasjon trenger inn og danner et farveskikt i polymeren. The present invention relates to a method for contrasting coloring of foot toys made from softened homo- or copolymerized PVC, based on the dye penetrating and forming a color layer in the polymer by migration.
Fottoy fremstilt av f.eks. mykgjort PVC vil gjerne få en ytre struktur som kan virke billig og kjedelig. For å bote på dette kan man gi ovennevnte fottoymateriale et spesielt overflatepreg som gir fottoyet et utseende som om det skulle vært fremstilt av et mer tiltrekkende og eksklusivt materiale. Photo toys produced by e.g. softened PVC will like to have an outer structure that can appear cheap and boring. To remedy this, the above-mentioned foot toy material can be given a special surface finish which gives the foot toy an appearance as if it had been made from a more attractive and exclusive material.
Ved produksjon av fottoy efter skallstopings-prosessen , som beskrevet i britisk patent nr. 726 784/eller efter kjente sproyte-stopingsprinsipper, er det mulig å behandle formene på en slik måte at man kan frembringe nær sagt enhver overflatestruktur. In the production of foot toys according to the shell stuffing process, as described in British patent no. 726 784/or according to known spray stuffing principles, it is possible to treat the molds in such a way that almost any surface structure can be produced.
For fottoy fremstilt efter f.eks. skallstopings—prosessen er For foot toys manufactured after e.g. the shell stuffing process is
det imidlertid ikke mulig farvemessig å skille sålen og over-lærets enkelte komponenter. Dette betyr i praksis at fottoyet får lik farve over hele overflaten, hvilket medforer at fottoyet får et plastaktig og billig preg. however, it is not possible to distinguish the individual components of the sole and upper leather in terms of colour. In practice, this means that the foot toy gets the same color over the entire surface, which means that the foot toy gets a plastic-like and cheap feel.
Man kan gjore ovennevnte fottoy mere tiltrekkende og salgbart One can make the above-mentioned foot toys more attractive and salable
og dessuten lofte det opp fra lavprisgruppen ved å påfore fottoyet utvendig en kontrastfarve eller ved en skyggelegging av overflaten, hvorved sålen, sommen eller andre komponenter på fottoyet fremheves. and furthermore lift it up from the low price group by applying a contrasting color to the outside of the foot toy or by shading the surface, whereby the sole, the sole or other components of the foot toy are highlighted.
En slik skyggelegging kan ifolge det kjente prinsipp utfores Such shading can be carried out according to the known principle
ved å påsproyte eller bemale overflaten med en maling eller en farvet lakk. by spraying or painting the surface with a paint or a colored varnish.
Ved bemaling eller lakkering av fottoy på basis av mykgjort PVC er man imidlertid spesielt utsatt for vekksliting av kontrast-farvestoffene, fordi en maling- eller lakk-film vil hefte dårlig til dette underlag. However, when painting or varnishing foot toys based on softened PVC, you are particularly exposed to wear and tear of the contrast dyes, because a paint or varnish film will adhere poorly to this substrate.
Videre er den ide kjent å farve mykgjort PVC med et farvestoff som er beregnet på å migrere inn i plasten. Denne ide har imidlertid ikke tidligere kommet til anvendelse, hvilket f.eks. fremgår av artikkelen i "Gummi, Asbest, Kunststoffe", oktober 1963, side 977-981, av Dr. Bruno Hirsekorn: "Das Fårben von Polyvinyl-chlorid". Fordommene er sannsynligvis et resultat av at man ikke har anvendt egnede farvestoffer og ikke anvendt en egnet farve-stoffpåforingsmetode. Derfor er denne metode ikke kommet til anvemdelse ved farving av PVC-fottoy. Furthermore, the idea is known to color softened PVC with a dye intended to migrate into the plastic. However, this idea has not previously been used, which e.g. appears from the article in "Rubber, Asbest, Kunststoffe", October 1963, pages 977-981, by Dr. Bruno Hirsekorn: "Das Fårben von Polyvinyl-chlorid". The prejudices are probably a result of not using suitable dyes and not using a suitable dye application method. Therefore, this method has not come into use when coloring PVC foot toys.
For eksempel kan man tenke seg at man ved tidligere forsbk basert på denne ide, har forsokt å påfore farvestoffet ved å dyppe PVC-gjenstanden i en farvestoffopplosning. Denne metode gir ikke tilfredsstillende resultat fordi losningsmidlet vasker vekk mykningsmidlet i PVC-overflaten, og derfor hindres migrasjon inn i overflaten, eftersom farvestoffmigrasjonen er betinget av til-stedeværelsen av mykningsmidlet. Videre blir farvestoffkonsen-trasjonen i overflaten for liten, og dessuten er oppholdstiden i badene for kort. For example, one can imagine that in previous experiments based on this idea, one tried to apply the dye by dipping the PVC object in a dye solution. This method does not give satisfactory results because the solvent washes away the plasticizer in the PVC surface, and therefore migration into the surface is prevented, since dye migration is conditioned by the presence of the plasticizer. Furthermore, the dye concentration in the surface is too small, and moreover the residence time in the baths is too short.
Formålet med oppfinnelsen er å eliminere ovennevnte ulemper ved The purpose of the invention is to eliminate the above-mentioned disadvantages of
å videreutvikle den ide å la farvestoffet migrere inn i den mykgjorte PVC. to further develop the idea of allowing the dye to migrate into the softened PVC.
Foreliggende oppfinnelse gjelder således en fremgangsmåte for kontrastfarving av fottoy fremstilt av mykgjort homo- eller kopolymerisert PVC, basert på at farvestoffet ved migrasjon trenger inn og danner et farveskikt i polymeren, karakterisert ved at ett eller flere organiske farvestoffer som er opplbselige i mykningsmidlet, påfores fottoyets overflate i pulverform, opplost i et organisk losningsmiddel, eller dispergert i et egnet dispergeringsmiddel. The present invention thus relates to a method for contrasting coloring of foot toys made from softened homo- or copolymerized PVC, based on the dye penetrating through migration and forming a color layer in the polymer, characterized in that one or more organic dyes that are soluble in the softener are applied to the foot toys surface in powder form, dissolved in an organic solvent, or dispersed in a suitable dispersant.
Derved er det til tross for fordommene tilveiebrakt en fremgangsmåte som gir en meget god farving på grunn av at man i onsket grad får utnyttet de spesielle farvestoffers evne til å migrere i det tilstedeværende mykningsmidde1. Thereby, despite the prejudices, a method has been provided which gives a very good dyeing due to the fact that the ability of the special dyes to migrate in the softening agent present is exploited to the desired extent1.
Alt efter hvilket farvestoff som anvendes, vil dette kunne for- Depending on which dye is used, this could cause
dele seg gjennom hele plasttverrsnittet eller bare i overflaten. split through the entire plastic cross-section or only in the surface.
Fordelen ved foreliggende prinsipp til forskjell fra tidligere The advantage of the present principle in contrast to previous ones
kjent teknikk, er at maling og lakk som legges utenpå et fottoymateriale av plast, lett kan skrapes vekk eller bli slitt av ved bruk, hvorved fottoyet får et mindreverdig og sjuskete utseende. known technique, is that paint and varnish applied to the outside of a plastic foot toy material can easily be scraped off or worn off during use, whereby the foot toy takes on an inferior and sloppy appearance.
Efter denne oppfinnelse vil farvestoffet trenge inn i fottoymaterialet og derved forankre seg så godt at det ikke lar seg slite bort uten at fottoyets ytre struktur blir odelagt. According to this invention, the dye will penetrate into the foot toy material and thereby anchor itself so well that it cannot be worn away without the outer structure of the foot toy being destroyed.
Farvestoffene som anvendes ifolge oppfinnelsen skal vise lose- The dyes used according to the invention must show loose
lighet i organiske mykgjorere av primær og sekundær art. Som myknere av primær art kan nevnes: Dioktylftalat, didecylftalat, diisooktyladipat, didecyladipat, dioktylsebacat. Myknere av sekundær art kan være: Dodecylbensen, parafinvoks. Som polymer- similarity in organic plasticizers of primary and secondary nature. Primary softeners include: Dioctyl phthalate, didecyl phthalate, diisooctyl adipate, didecyl adipate, dioctyl sebacate. Secondary softeners can be: Dodecylbenzene, paraffin wax. As polymer-
materiale kan i denne forbindelse nevnes homo- og kopolymere polyvinylklorider, eksempelvis polyvinylklorid-polyvihylacetat, polyvinylklorid-polyvinylidenklorid. material can be mentioned in this connection homo- and copolymer polyvinyl chlorides, for example polyvinyl chloride-polyvinyl acetate, polyvinyl chloride-polyvinylidene chloride.
Farvestoffene skal vise loselighet i ovennevnte media og dessuten danne transparente losninger med disse og hore inn under gruppene: Sure farvestoffer, basiske farvestoffer, fellings-gruppen av de sure og basiske farvestoffer samt enkelte organiske metallkomplekser. Som eksempel på ovennevnte farvestoffer kan nevnes: Kvasinoytrale azofarvestoffer og azofarvestoffer av enklere oppbygning, Anilinfarvestoff, Azinfarvestoff og Xanten-farvestoff samt Antrakinonfarvestoff. The dyes must show solubility in the above-mentioned media and also form transparent solutions with these and fall under the groups: Acidic dyes, basic dyes, the precipitation group of the acidic and basic dyes as well as some organic metal complexes. Examples of the above-mentioned dyes can be mentioned: Quasi-neutral azo dyes and azo dyes of a simpler structure, Aniline dye, Azin dye and Xanten dye as well as Anthraquinone dye.
Slike farvestoffer markedfores blant annet under folgende navn: "Irgazetschwarz RL""Grazol Echt braun""Du Pont Oil Brown" "Fettschwarz HBVFluorol 5 G<1>;"Sudan I<1>;"Oil Red OS""Naphtylamin Bordeaux1; " Indulin 3 B." Such dyes are marketed, among other things, under the following names: "Irgazetschwarz RL" "Grazol Echt braun" "Du Pont Oil Brown" "Fettschwarz HBVFluorol 5 G<1>;"Sudan I<1>;"Oil Red OS""Naphthylamine Bordeaux1; " Indulin 3 B."
Farvestoff av denne art utskilles på fottbyoverflaten som farvekorn efterhvert som losnings- eller dispergeringsmidlet fordam-per. Disse farvekorn har den egenskap at de gradvis loser seg i mykneren og trenger inn i plastmaterialet. Derved dannes det et farveskikt i selve fottoymaterialet, hvilket farveskikt ikke lar seg fjerne uten at også selve fottoymaterialet nedslites eller fjernes. Dyestuff of this kind is secreted on the footby surface as dye grains as the solvent or dispersant evaporates. These color grains have the property that they gradually loosen in the plasticizer and penetrate the plastic material. Thereby, a color layer is formed in the foot toy material itself, which color layer cannot be removed without the foot toy material itself also wearing down or being removed.
Fottoy som skyggelegges eller påfbres kontrastfarve ifblge den foreliggende oppfinnelse, vil derfor selv ved kraftig slitasje bevare kontrastfarven. Dette oker fottoyets anvendelighet og styrker dets salgsappell. Foot toys that are shaded or applied contrasting color according to the present invention will therefore retain the contrasting color even with heavy wear. This increases the photo toy's usability and strengthens its sales appeal.
Eksempel I Example I
Fottoy på basis av mykgjort homo- og kopolymerisert PVC fremstilt ved skallstbpings -prosessen eller ved sproytestoping ble farvelagt med kontrastmaling av i og for seg kjent type, f.eks. vinyl- og akrylmaling, basert på bindemidler av typen kopolymere og homopolymere vinyl- og akrylforbindelser, hvori det var innrevet uloselige farvestoffer av gruppen pigmenter. Foot toys based on softened homo- and copolymerized PVC produced by the shell stbping process or by spray stopping were colored with contrast paint of a known type, e.g. vinyl and acrylic paint, based on binders of the type copolymer and homopolymer vinyl and acrylic compounds, in which insoluble dyes from the group of pigments were incorporated.
Eftersom slike malingtyper ikke har tilstrekkelig hefteevne til fottoymaterialet, ble farveskiktet efter kort tids bruk slitt eller skrapet vekk, hvorved fottoyets utseende raskt ble forrin-get. Since such types of paint do not have sufficient adhesion to the foot toy material, the color layer was worn or scraped off after a short period of use, whereby the appearance of the foot toy quickly deteriorated.
Eksempel_II Example_II
Fottoy basert på samme materiale som i eksempel I, ble farvelagt med kontrastmaling basert på linolje og dets kopolymere, hvori det var innrevet pigmenter. Foot toys based on the same material as in example I were colored with contrast paint based on linseed oil and its copolymers, in which pigments were incorporated.
Kontrastfarven tok i dette tilfellet opp mykgjorer fra fottoyet og ble seig og klissen, og farveskiktet lot seg lett skrape vekk. Fottoy som er farvelagt på denne måte, er uselgelig. In this case, the contrast color picked up plasticizers from the foot toy and became tough and sticky, and the color layer was easily scraped away. Foot toys colored in this way are unsellable.
Eksempel_III Example_III
0,2 % opplosning av Irgazet-braun 2 RL i metyletylketon ble påfort fottoy fremstilt ved skallstoping eller sproytestoping og av materiale som i eksempel I. Efter kort tid fordampet losningsmidlet, og farvestoffet trengte inn i fottoymaterialet fot" i dette å danne et farveskikt som således ikke kunne fjernes uten at også selve fottoymaterialet ble fjernet. A 0.2% solution of Irgazet-braun 2 RL in methyl ethyl ketone was applied to foot toys produced by shell stuffing or spray stuffing and of material as in example I. After a short time the solvent evaporated, and the dye penetrated into the foot toy material foot" in this to form a color layer which thus could not be removed without also removing the foot toy material itself.
Dette betyr at fottoyet vil beholde sin tiltenkte kontrastfarve helt til selve fottoymaterialet er slitt vekk. This means that the foot toy will retain its intended contrasting color until the foot toy material itself is worn away.
Eksempel_IV Example_IV
0,24 % opplosning av Irgazetbraun 2 RL og Fettschwarz HB i for-holdet 2:1 ble påfort fottoyet som i eksempel III. 0.24% solution of Irgazetbraun 2 RL and Fettschwarz HB in the ratio 2:1 was applied to the foot toy as in example III.
Efter kort tid fordampet losningsmidlet, og farvestoffet trengte inn i fottoyet og dannet der et farveskikt som ikke lot seg fjerne uten å odelegge selve fottoyets overflate. After a short time the solvent evaporated, and the dye penetrated the foot toy and formed a color layer there that could not be removed without destroying the foot toy's surface itself.
Eksempel V Example V
0,10 % opplosning av Du Pont Oil Brown i aceton ble påfort fottoyet som beskrevet i eksempel III. 0.10% solution of Du Pont Oil Brown in acetone was applied to the foot toy as described in Example III.
Efter kort tid fordampet losningsmidlet, og farvestoffet trengte inn i fottoyet og dannet der et farveskikt som ikke kunne fjernes ved bruk av fottoyet eller uten at fottoyets ytre struktur ble endret. After a short time the solvent evaporated, and the dye penetrated the foot toy and formed a color layer there that could not be removed when using the foot toy or without the foot toy's outer structure being changed.
