Description
Przedmiotem wynalazku jest srodek do szybkie¬ go odklejania tkanin. Srodek moze byc stosowany w operacjach usuwania klejonki skrobiowej z os¬ nowy tkanin w procesach bielenia.The present invention relates to a quick-release agent it peel off fabrics. The measure can be used in operations for de-sizing starch from os new fabrics in bleaching processes.
Naniesione na osnowy tkackie klejonki zwiek¬ szajace wytrzymalosc osnowy i zapewniajace dobry poslizg czólenka tkackiego przeszkadzaja w chemi¬ cznej obróbce tkanin i musza byc z nich usuniete przed operacja bielenia wlasciwego.The large size sizings applied to the weaving warps excellent carcass strength and good the slip of the weaving shuttle is obstructing the chemistry treating fabrics and must be removed prior to actual bleaching.
Operacje odklejania tkanin przeprowadza sie róz¬ nie w zaleznosci od rodzaju klejonki i sposobu bie¬ lenia wlasciwego. W przemysle bawelnianym uzy¬ wane sa glównie tradycyjne klejonki skrobiowe.The operations for detaching the fabrics are carried out in roses not depending on the type of sizing and the way of running proper lazy. In the cotton industry, it is used mainly traditional starch dressings are important.
Usuwanie krochmalu z tkaniny polega na prze¬ prowadzeniu skrobi w rozpuszczalne w wodzie cu¬ kry proste. Operacje te przeprowadza sie za po¬ moca goracej wody, enzymów lub zwiazków chemi¬ cznych. Odklejanie sama woda jest dlugotrwale i w praktyce nie jest juz stosowane. Znane sa szyb¬ sze sposoby, w których pod dzialaniem czynników hydrolitycznych zarówno kwasowych jak i zasado¬ wych skrobia przechodzi w glukoze.The removal of starch from the fabric is accomplished by converting starch into water-soluble sugar simple ice floes. These operations are performed for after the strength of hot water, enzymes or chemicals civic. Peeling off the water itself is a long-lasting and in practice it is no longer used. They are known to be fast six ways in which influenced by factors hydrolytic acids, both acidic and alkaline starch turns into glucose.
Odklejanie tkanin metoda kapieli kwasnej prze¬ prowadza sie dodajac do wody 0,5—l*Vo kwasu sol¬ nego lub siarkowego — podwyzszenie temperatury odklejania przyspiesza przebieg procesu jest jednak niebezpieczne, gdyz przy miejscowym odparowaniu wody kwas moze uszkodzic wlókno.Removal of fabrics by the acid bath method is carried out by adding 0.5 to 1% of hydrochloric acid to water or sulfuric acid - temperature increase Peeling off speeds up the course of the process, however dangerous because with local evaporation Acid water can damage the fiber.
Rozszczepienie skrobi w kapieli alkalicznej jest bezpieczniejsze lecz w obydwu opisanych przypad¬ lo kach proces trwa 6—8 godzin i wymaga tak zwa¬ nego moczenia tkaniny, to jest pozostawienia jej po zamoczeniu na kilka godzin w spokoju. Najbez¬ pieczniejszym znanym sposobem jest odklejanie za pomoca enzymów diastatycznych. Najczesciej sto¬ suje sie diasfor w ilosci 1—2 g na litr kapieli na¬ pawajacej w temperaturze 55—65°C. Po napojeniu tkaniny uklada sie ja w dolach na przeciag 4—6 godzin.The cleavage of starch in an alkaline bath is safer but in both cases described lo The process takes 6-8 hours, and so requires soaking the fabric, that is, leaving it after getting wet for a few hours alone. Most without the safer known way is peeling off behind help with diastatic enzymes. Mostly a hundred Diasforium is used in the amount of 1-2 g per liter of bath per liter at a temperature of 55-65 ° C. After drinking the fabric is placed in the pits on the 4-6 hours.
Bardzo rozpowszechnione jest stosowanie metod odklejania tkanin srodkami utleniajacymi. Odkleja¬ nie srodkami utleniajacymi polaczone jest z czes¬ ciowym bieleniem, stosuje sie nadboran sodowy, nadtlenek sodowy, wode utleniona oraz podchlo¬ ryn sodowy. Stosujac srodki utleniajace mozna skrócic czas odklejania do 5 a nawet do 3 godzin przy niskim naniesieniu klejonki. Mimo duzej re¬ aktywnosci skrobi proces chemicznej degradacji klejonek skrobiowych jest bardzo trudny, dlatego, ze czynniki powodujace rozklad skrobi oddzialy- wuja równiez na wlókno celulozowe powodujac je¬ go degradacje, co pociaga za soba zmiane dlugosci lancucha celulozy i zwiazane z tym zmiany wlas¬ nosci szczególnie mechanicznych i wytrzymaloscio¬ wych.The use of methods is very common detaching fabrics with oxidizing agents. Peel off it is combined with Czech non-oxidizing agents bleach, sodium perborate is used, sodium peroxide, hydrogen peroxide and hypochlorite soda gutter. By using oxidizing agents you can reduce the peeling time to 5 or even 3 hours with low application of sizing. Despite the large re¬ starch activity, the process of chemical degradation starch size is very difficult, therefore, that the factors that break down starch are my uncle's cellulose, too, causing them degradation, which entails a change in length cellulose chain and the related changes to its property especially mechanical and durability out.
Szczególnie ostroznie nalezy przeprowadzac pro¬ ces odklejania srodkami utleniajacymi, gdyz kazde niedopatrzenie moze spowodowac nieodwracalne zmiany strukturalne celulozy. Innym powaznym mankamentem znanych metod odklejania tkanin l04 134a 104134 4 celulozowych jest dlugi czas trwania procesu i to, ze tkanina po namoczeniu powinna lezec.The procedure should be carried out with particular care the process of detaching with oxidizing agents, because any an oversight may make you irreversible structural changes in cellulose. Another serious one drawback of known methods of detaching fabrics l04 134a 104134 4 cellulosics is a long process time and that that the fabric should lie down after soaking.
Jak juz wspomniano odklejanie tkanin bawel¬ nianych jest jedna z operacji procesu bielenia i w zaleznosci od obranej metody bielenia, operacja od- klejania ma z góry zalozone pewne warunki. Cho¬ dzi tu glównie o sposób i forme prowadzenia tka¬ niny co z kolei wplywa na stosowanie takich czy innych srodków odklejajacych. Rozróznia sie biele¬ nie tkanin w pasmie i bielenie tkanin w szerokosci.As already mentioned, peeling of cotton fabrics one of the operations of the bleaching process is involved, and depending on the chosen method of bleaching, the operation of bonding has certain pre-requisites. Cho¬ today it is mainly about the way and form of weaving nina which, in turn, affects the use of such or other removers. There are whites no fabrics in the strand and bleaching of fabrics in width.
Tak w jednej jak i drugiej metodzie moga byc stosowane procesy okresowe, pólciagle i ciagle. W dwu ubieglych dzisiecioleciach istniala tendencja bielenia tkanin w pasmie. Od kilkunastu lat obser¬ wuje sie nawrót do metod bielenia szerokosciowe¬ go. Znane sa agregaty przeznaczone do ciaglego bielenia tkanin w szerokosci. Znane srodki odkle- jajace nie zapewniaja bezpiecznej i sprawnej pra¬ cy tych agregatów. Znany jest srodek do odkleJa¬ nia o którym wiadomo, ze jest wyzszym estrem alkoholowym kwasu jednonadsiarkowego, stabili¬ zowanym specjalna metoda.Both can be used in both methods batch, semi-continuous and continuous processes used. IN in the last two decades there has been a tendency bleaching fabrics in a band. For several years, he has been observing There is a return to wide-width bleaching methods him. Continuous aggregates are known bleaching fabrics in width. Known removals eggs do not provide safe and efficient work of these aggregates. A de-sticking agent is known is known to be a higher ester alcohol monopersulfuric acid, stabilized a special method.
Celem wynalazku bylo znalezienie srodka zapew¬ niajacego bezpieczny i szybki przebieg procesu od¬ klejania skrobi z tkanin celulozowyclu szczególnie przydatnego do bielenia tkanin w szerokosci me¬ toda ciagla.The object of the invention was to find a means of ensuring the safe and quick course of the process gluing starch from cellulose fabrics, especially useful for bleaching fabrics across the width of the meats continuous.
Istota wynalazku polega na zastosowaniu w srod¬ ku odklejajacym zwiazków lagodzacych skutki nie¬ korzystnego oddzialywania zwiazków utleniajacych na wlókno celulozowe.The essence of the invention consists in its use in towards detachable compounds that alleviate the effects of not beneficial effect of oxidizing compounds for cellulose fiber.
Nieoczekiwanie stwierdzono, ze proces odklejania tkanin celulozowych przy uzyciu zwiazków utlenia¬ jacych mozna uczynic znacznie bardziej bezpie¬ cznym jesli przeprowadza sie go w obecnosci zwiaz¬ ków zawierajacych ugrupowanie Ri—C—N—CH2OH II I O R2 gdzie Ri stanowi alkil, grupe —NH2 lub —O—, a R2 stanowi wodór, alkil lub grupe —CH2OH. Juz niewielki dodatek tych zwiazków do mieszaniny zwiazku utleniajacego, mocznika i siarczanu sodo¬ wego powoduje, ze mieszanina taka stosowana mo¬ ze byc bezpiecznie w operacjach ciaglego odklejania tkanin w szerokosci. Korzystne wlasnosci wykazuje zastosowana w roli zwiazku lagodzacego w srodku wedlug wynalazku mieszanina dwu/hydroksyme- tylo/uretanów alkoholi alifatycznych o dlugosci lancucha weglowodorowego ód C10 do C22 oksyety¬ lowanych 10—20 molami tlenku eitylenu. Do te¬ go celu nadaje sie równiez hydroksymetylomocz- nik.Unexpectedly found that the peel process of cellulose fabrics with the use of oxidation compounds that can be made much safer jointly if it is carried out in the presence of a relationship containing a Ri — C — N — CH2OH moiety II I About R2 where Ri is alkyl, the group -NH2 or -O-, a R2 is hydrogen, alkyl or -CH2OH. Already a slight addition of these compounds to the mixture oxidizing compound, urea and sodium sulfate the mixture is used in this manner to be safe in continuous peel operations fabrics in width. It shows favorable properties used as a soothing compound inside according to the invention, a mixture of di / hydroxyme- tylo / urethane aliphatic alcohols in length Hydrocarbon chain from C10 to C22 oxyethyl coated with 10-20 moles of eityl oxide. To te Also suitable for this purpose are hydroxymethyl nik.
