Description
Fremgangsmåte til behandling av polyamidfibre. Process for treating polyamide fibers.
Det er allerede blitt foreslått å be-handle polyamidfibre med peroksydholdige bleke- og vaskemidler, hvorunder det for å skåne fibrene tilsettes vaske- eller bleke-badet organiske kvelstofforbindelser som inneholder minst to amino-, imino- eller nitrilo-grupper i molekylet og av hvike den ene er av primær eller sekundær natur og den annen av primær, sekundær eller tertiær natur. Disse to kvelstoffgrupper er forbundet med hverandre ved en overvei-ende mettet kullvannstoffkjede som ikke inneholder mer enn 6 kullstoffatomer. Kullvannstof f kjeden kan være erstattet med eller avbrutt av en ringformig anordning av mettet eller aromatisk natur og kan eventuelt også være avbrutt av ett eller flere heteroatomer. It has already been proposed to treat polyamide fibers with peroxide-containing bleaching and washing agents, whereby organic nitrogen compounds containing at least two amino, imino or nitrilo groups in the molecule and of which one is of primary or secondary nature and the other of primary, secondary or tertiary nature. These two nitrogen groups are connected to each other by a predominantly saturated carbon hydrogen chain containing no more than 6 carbon atoms. Carbon hydrogen f the chain may be replaced by or interrupted by a ring-shaped arrangement of a saturated or aromatic nature and may optionally also be interrupted by one or more heteroatoms.
I henhold til den foreliggende oppfin-nelse er en fremgangsmåte til behandling According to the present invention, there is a method for treatment
av polyamidfibre eller derav fremstilte garn, vevnader eller strikkede varer med peroksydholdige bleke- eller vaskemidler i nærvær av beskyttelsesstoffer, hvor det som beskyttelsesstoffer anvendes slike organiske kvelstofforbindelser som i sitt molekyl inneholder minst to amino-, imino-eller nitrilgrupper, av hvilke minst en må inneholde et aktivt vannstoffatom, og hvor of polyamide fibers or yarns, weaves or knitted goods made from them with peroxide-containing bleaches or detergents in the presence of protective substances, where the protective substances used are such organic nitrogen compounds which in their molecule contain at least two amino, imino or nitrile groups, of which at least one must contain an active hydrogen atom, and where
disse to kvelstoffholdige grupper er forbundet med hinannen over en rett eller forgrenet kullstoff kjede med 1—9 C-atom-er, som eventuelt kan være avbrutt av et eller flere heteroatomer, fortrinsvis kvelstoff, karakterisert ved at minst ett vannstoffatom i den forbindende kullstoff kjede er substituert med en eller flere av gruppene: NH, —NHo, =NOH eller —NHOH. these two nitrogen-containing groups are connected to each other via a straight or branched carbon chain with 1-9 carbon atoms, which may optionally be interrupted by one or more heteroatoms, preferably nitrogen, characterized by at least one hydrogen atom in the connecting carbon chain is substituted by one or more of the groups: NH, —NHo, =NOH or —NHOH.
Kullstoff kjeden kan også være erstattet The carbon chain can also be replaced
med eller avbrutt av en ringformet anordning av mettet eller aromatisk natur, som likeledes kan inneholde ett eller flere heteroatomer. with or interrupted by a ring-shaped arrangement of a saturated or aromatic nature, which may likewise contain one or more heteroatoms.
Likeledes har det i mange tilfelle vist seg fordelaktig å anvende kvelstoff-forbindelser i hvilke også minst en amino-eller iminogruppe er helt eller delvis substituert. Likewise, in many cases it has proven advantageous to use nitrogen compounds in which at least one amino or imino group is also fully or partially substituted.
Helt generelt har det vist seg fordelaktig å ha en størst mulig opphoping av kvelstoffgrupper i molekylet. Det er der-for å anbefale at man som substituenter for kullvannstof f kjeden anvender slike heteroatomer og kvelstoffgrupper som også på sin side inneholder kvelstoff. In general, it has proven advantageous to have the largest possible accumulation of nitrogen groups in the molecule. It is there to recommend that such heteroatoms and nitrogen groups are used as substituents for carbon hydrogen in the chain which also contain nitrogen.
I andre tilfelle, spesielt når man vil innvirke på oppløseligheten av dé anvendte forbindelser er dett å anbefale å velge slike substituenter som inneholder en fenyl-gruppe. In other cases, especially when one wants to influence the solubility of the compounds used, it is recommended to choose such substituents which contain a phenyl group.
Fosrøk har vist at forbindelsene i henhold til oppfinnelsen har en særlig god virksomhet som fiberbeskyttelsesmidler. Fosrøk has shown that the compounds according to the invention have a particularly good activity as fiber protectants.
Således blir det eksempelvis ved oksalsyrediamidoksim This is the case, for example, with oxalic acid diamidoxime
oppnådd en bedre virkning enn ved det enkeltbygde etylen-diamin som har forme-len H2N - CH,, - CH2 - NH2. I de fleste til-fellle kan man med et mol oksalsyrediamidoksim oppnå omtrent den 5-dobbelte virkning sammenliknet med et mol etylen-diamin. Som ovenfor nevnt kan man også lede cppløseHgheten av de i henhold til oppfinnelsen benyttede beskyttelsesstoffer i be-stemte retninger, hvilket tekstilkjemisk er av betydning; således er f. eks. oksalsyre-bis-fenylamidin uoppløselig i vann av 50° C og oksalsyrediamidoksim kan ved den samme temperatur oppløses i en mengde av 50 gr. pr. liter vann. Som alminnelig regel kan det sies at substituering med alkylgrupper praktisk talt ikke påvirker beskyttelsesvirkningen. En viss virkningsøkning oppnås ved substituering med fenylgrupper, hvorunder dessuten denne substituering kan være av betydning fordi den påvirker oppløselig-heten. De beste virkninger oppnås hvis det som substituenter anvendes NH2, NH =, N - eller HON-gruppene. På grunn av den nye erkjennelse ble tallrike nye stoffer fastslått å være ut-merkede beskyttelsesmidler i oppfinnelsens forstand. Som eksempler kan her nevnes bensaldehydguanylhydrazon achieved a better effect than with the single-built ethylenediamine which has the formula H2N - CH,, - CH2 - NH2. In most cases, one mole of oxalic acid diamidoxime can achieve approximately the 5-fold effect compared to one mole of ethylene diamine. As mentioned above, the solubility of the protective substances used in accordance with the invention can also be directed in specific directions, which is important in terms of textile chemistry; thus, e.g. Oxalic acid bis-phenylamidine is insoluble in water at 50° C and oxalic acid diamidoxime can be dissolved at the same temperature in a quantity of 50 gr. per liters of water. As a general rule, it can be said that substitution with alkyl groups practically does not affect the protective effect. A certain increase in effectiveness is achieved by substitution with phenyl groups, during which this substitution can also be of importance because it affects the solubility. The best effects are achieved if the NH 2 , NH = , N - or HON groups are used as substituents. Due to the new realization, numerous new substances were determined to be excellent protective agents in the sense of the invention. Examples include benzaldehyde guanylhydrazone
i in
og N,N-pentametylen - N' - guanyl-guanidin and N,N-pentamethylene-N'-guanyl-guanidine
Av de følgende eksempler fremgår at iminogruppen som substituent øker virk-somheten, mens karbonylsurstoff derimot ikke gjør det: Videre alkylsubstitusjon av den sist-nevnte forbindelse til N-fenyl-N-metyl-N'-guanylguanidin From the following examples it appears that the imino group as a substituent increases the activity, while carbonyl oxygen, on the other hand, does not: Further alkyl substitution of the last-mentioned compound to N-phenyl-N-methyl-N'-guanylguanidine
forandrer ikke virkningen nevneverdig. Står metylgruppen ved bensolringen inn-trer det heller ikke noen økning av virkningen. does not significantly change the effect. If the methyl group is at the benzene ring, there is no increase in the effect either.
At substitusjon med NH2-grupper brin-ger fordeler sammenlignet med substitusjon med andre grupper, i dette tilfelle med karboksylgrupper, viser seg ved føl-gende oppstilling: That substitution with NH2 groups brings advantages compared to substitution with other groups, in this case with carboxyl groups, is shown by the following arrangement:
Også HON = gruppen i hydroksimsyreformuleringen virker effektøkende likesom HON-gruppen i oksimer The HON = group in the hydroxy acid formulation also has an effect-enhancing effect, just like the HON group in oximes

Polymerisert s-lakten-silke som til sammenlikning ble bleket uten 2-metylbensimidazol under de samme betingelser viste en styrke på bare 32,3 riv/km hvilket svarer til et tap på 31,4 pst. Polymerized s-lacten silk which, for comparison, was bleached without 2-methylbenzimidazole under the same conditions showed a strength of only 32.3 riv/km which corresponds to a loss of 31.4 per cent.
Benytter man i stedet for det her anvendte 2-metylbensimidazol den ikke substituerte bensimidazol, er beskyttelses-effekten molmessig ikke mindre, men metylsubstituenten økte heller ikke virk-somheten, hvilket derimot entydig bevises i eksempel 2 med oksimgruppen. har titeren 20 den. behandles i 2 timer ved 85°C og et badforhold på 1 : 30 i føl-gende blekebad: If, instead of the 2-methylbenzimidazole used here, the unsubstituted benzimidazole is used, the protective effect is no less in terms of molarity, but the methyl substituent did not increase the activity either, which, on the other hand, is unequivocally proven in example 2 with the oxime group. has the title 20 the. treated for 2 hours at 85°C and a bath ratio of 1:30 in the following bleach bath:
