Description
Fremgangsmåte til bleking med vandige oppløsninger av alkali-eller jordalkalikloritter. Procedure for bleaching with aqueous solutions of alkali or alkaline earth chlorites.
Det er kjent å anvende vandige opp-løsninger av alkali- eller jordalkalikloritter til bleking av forskjellige stoffer, særlig av bomull eller bomullsvarer. Herunder aktiveres disse oppløsninger vanligvis ved tilsetning av syrer. Denne tilsetning har imidlertid den ulempe at klordioksyd fri-gjøres allerede under avkjøling. Klordiok-sydet som danner seg innvirker på den ene side fysiologisk meget ubehagelig, på den annen side forårsaker det korrosjoner. It is known to use aqueous solutions of alkali or alkaline earth chlorites for bleaching various substances, particularly cotton or cotton goods. Below these solutions are usually activated by the addition of acids. However, this addition has the disadvantage that chlorine dioxide is already released during cooling. The chlorine dioxide that forms has a physiologically very unpleasant effect on the one hand, and on the other hand it causes corrosion.
Det er videre kjent å anvende forskjellige stoffer som aktivatorer for klorittopp-løsninger. It is also known to use various substances as activators for chlorite solutions.
Det ble nå funnet at klorittoppløsnin-ger kan aktiveres på utmerket måte, når man tilsetter dem heksametylentetramin. Klorittoppløsninger som er blandet med heksametylentetramin utvikler ikke klordioksyd under avkjøling. Først ved høyere temperaturer, særlig ved temperaturer på ca. 50° C og derover finner det sted en bleking i nærvær av de stoffer som skal blekes, særlig av celluloseholdige stoffer. It was now found that chlorite solutions can be activated in an excellent way when hexamethylenetetramine is added to them. Chlorite solutions mixed with hexamethylenetetramine do not evolve chlorine dioxide on cooling. First at higher temperatures, especially at temperatures of approx. At 50° C and above, bleaching takes place in the presence of the substances to be bleached, particularly cellulose-containing substances.
Det har videre vist seg som fordelaktig pr. mol kloritt å tilsette 0,01 til 0,5 mol av aktivatoren. It has also proven to be beneficial per moles of chlorite to add 0.01 to 0.5 moles of the activator.
Eksempel 1: Example 1:
Avklistret neslevevnad impregneres Peeled-off nasal tissue is impregnated
med en vandig oppløsning, som pr. liter inneholder 12 g NaC102, 1,2 g heksametylentetramin og 1,0 g av et fuktemiddel (Arbyl N) og holdes deretter i tre timer ved 78° C i et lukket kar. Blekeoppløsningens pH-verdi utgjør ved begynnelsen 9,2, etter with an aqueous solution, which per liter contains 12 g NaC102, 1.2 g hexamethylenetetramine and 1.0 g of a wetting agent (Arbyl N) and is then kept for three hours at 78° C in a closed vessel. The pH value of the bleaching solution is 9.2 at the beginning, after
blekingen 4,6. Vevnadens hvithetsgrad er øket fra 60,3 % til 85,6 %. I 100 vektsdeler av vevnaden er det etter blekingen et innhold av bare 0,1 del uforbrukt kloritt. the bleaching 4.6. The degree of whiteness of the fabric has been increased from 60.3% to 85.6%. In 100 parts by weight of the fabric after bleaching, there is a content of only 0.1 part unused chlorite.
Arbeider man under de samme betin-gelser men uten tilsetning av heksametylentetramin så utgjør vevnadens hvithetsgrad bare 68,1 %. Etter blekningen inneholder 100 vektsdeler av vevnaden dessuten 1 del uforbrukt kloritt. If you work under the same conditions but without the addition of hexamethylenetetramine, the whiteness of the fabric is only 68.1%. After bleaching, 100 parts by weight of the fabric also contain 1 part of unused chlorite.
Eksempel 2: Example 2:
Avklistret skallholdig grovneslevevnad impregneres med en vandig oppløsning, som pr. liter inneholder 16 g NaC102, 1 g heksametylentetramin og 1 g av et fuktemiddel (Arbyl N) og holdes deretter i to timer ved 93° C i et lukket kar. Blekeopp-løsningens pH-verdi utgjør ved begynnelsen 9,2, etter blekingen 4,6. Vevnadens hvithetsgrad er øket fra 55,5 % til 84,6 %. I 100 vektsdeler av vevnaden er det etter blekingen bare et innhold av 0,2 deler uforbrukt kloritt. Peeled-off scaly nasal tissue is impregnated with an aqueous solution, which per liter contains 16 g of NaC102, 1 g of hexamethylenetetramine and 1 g of a wetting agent (Arbyl N) and is then kept for two hours at 93° C in a closed vessel. The pH value of the bleaching solution is 9.2 at the beginning, 4.6 after bleaching. The degree of whiteness of the fabric has been increased from 55.5% to 84.6%. In 100 parts by weight of the fabric after bleaching, there is only a content of 0.2 parts of unused chlorite.
Eksempel 3: Example 3:
Kordvevnad impregneres med en vandig oppløsning som pr. liter inneholder 14,4 g NaClOa, 1,4 g heksametylentetramin og 1,0 g av et fuktemiddel (Arbyl N) og holdes deretter i tre timer ved 78° C i et lukket kar. Blekeoppløsningens pH-verdi utgjør ved begynnelsen 9,2, etter blekingen 4,3. Baksidens hvithetsgrad øker fra 48,8 % til 78,1 %. I 100 vektsdeler vevnad er det etter blekingen ennå bare 0,12 deler uforbrukt kloritt. Cord fabric is impregnated with an aqueous solution that per liter contains 14.4 g of NaClOa, 1.4 g of hexamethylenetetramine and 1.0 g of a wetting agent (Arbyl N) and is then kept for three hours at 78° C in a closed vessel. The pH value of the bleaching solution is 9.2 at the beginning, 4.3 after bleaching. The whiteness of the reverse side increases from 48.8% to 78.1%. In 100 parts by weight of fabric, after bleaching there is still only 0.12 parts of unused chlorite.
Eksempel 4: En forrenset vevnad av rene polyamid-fibre impregneres med en vandig oppløs-ning som pr. ltr. inneholder 9,0 g NaC102, 0,9 g heksametylentetramin og 1,0 g av et fuktemiddel (arbyl N) og holdes deretter i to timer ved 80° C i et lukket kar. Bleke-oppløsningens pH-verdi utgjør ved begynnelsen 9,1, etter blekningen 5,5. Vevnadens hvithetsgrad er øket fra 79,3 % til 84,3 %. I 100 vektsdeler av vevnaden er det etter blekningen bare dessuten inneholdt 0,2 % uforbrukt kloritt. Example 4: A pre-cleaned fabric of pure polyamide fibers is impregnated with an aqueous solution which per ltr. contains 9.0 g of NaC102, 0.9 g of hexamethylenetetramine and 1.0 g of a wetting agent (arbyl N) and is then kept for two hours at 80° C. in a closed vessel. The pH value of the bleaching solution is 9.1 at the beginning, 5.5 after bleaching. The degree of whiteness of the fabric has been increased from 79.3% to 84.3%. In 100 parts by weight of the tissue there is the bleach only additionally contained 0.2% unconsumed chlorite.
