Description
Wynalazek dotyczy traktowania prze¬ dzy, nici, tkanin, wlókien lub innych mate¬ rialów pochodzenia roslinnego, np. bawel¬ ny i regenerowanego jedwabiu sztucznego z blonnika, z wyjatkiem jedwabiu z estrów blonnika, i ma na celu uodpornienie tych materialów przeciwko gnieceniu sie, zbiega¬ niu przy praniu i dzialaniu swiatla, jak równiez utrwalenie na dzialanie prania e- fektów wytworzonych na tych materialach na drodze mechanicznej.Wedlug wynalazku materialy traktuje sie obojetnymi wodnymi roztworami pro¬ duktu kondensacji mocznikowo - formalde¬ hydowej, po czym napojony material pod¬ daje sie traktowaniu zimnym zakwaszonym stezonym roztworem soli, która posiada znaczne powinowactwo wzgledem wody, nie powoduje jednak pecznienia wlókien blonnikowych. Material wlóknisty, napojo¬ ny jak wyzej, po wysuszeniu i kondycjono- waniu mozna poddac obróbce mechanicznej w celu zmiany ksztaltu jego powierzchni; w koncu traktuje sie go zimnym stezonym roztworem soli. W ten sposób efekty, wy¬ tworzone na drodze mechanicznej, np. kar¬ by, mora, efekt glace, utrwala sie bez po¬ trzeby dalszego kondensowania produktu dzialaniem ciepla. Dalsza kondensacja przebiega gladko w roztworze soli w tem¬ peraturze zwyklej.Sól i jej stezenie w roztworze dobiera sie tak, aby wlókna w temperaturze poko¬ jowej nie pecznialy wcale lub pecznialytylko w stopniu nieznacznym. Sola nadaja¬ ca sie do tego sposobu jest chlorek wapnia, uzyty w roztworze zawierajacym w litrze okolo 600 g bezwodnego chlorku wapnia.Podobnie mozna równiez stosowac chlorek magnezu i chlorek glinu; Stezenie roztworu "moze sie wahac w szerokich granicach, jak rówriiez i czas trwania traktowania roztwo¬ rem fsQli, który wynosi co najmniej kilka rhinut. Za pomoca roztworu chlorku wapnia osiaga sie np. dobre wyniki po uplywie oko¬ lo 10 minut. Roztwór soli zadaje sie nie¬ znaczna iloscia kwasu, np. 0,1 — 0,5% kwa¬ su solnego lub nieco wieksza iloscia kwasu slabszego, np. octowego.Po potraktowaniu materialu wlókienni¬ czego zakwaszonym roztworem soli plucze sie go poczatkowo woda, a nastepnie moz¬ na go namydlic na goraco lub traktowac dodatkowo w inny sposób odpowiedni.Glówna ceche wynalazku stanowi moz¬ liwosc osiagniecia wspomnianych we wste¬ pie wyników bez stosowania obróbki ciepl¬ nej materialu wlókienniczego.Przyklad I. Merceryzowana tkanine bawelniana napawa sie wodnym roztworem 16% mocznika dwumetylolowego i 0,8% al¬ dehydu mrówkowego. Roztwór ten jest zu¬ pelnie obojetny i nie zawiera zadnych ka¬ talizatorów. Po napawaniu tkanine suszy sie z lekka, po czym napawa sie zimnym roztworem, zawierajacym w litrze 600 g bezwodnego chlorkuj wapnia i 15 cm3 28%- owego kwasu solnego. Tkanine po napawa¬ niu pozostawia sie w spoczynku w stanie zlozonym lub zwinietym w ciagu co naj¬ mniej 15 minut, po czym plucze woda sla¬ bo zalkalizowana amoniakiem i wreszcie mydli i suszy. Po tym traktowaniu tkanina jest znacznie odporniejsza na gniecenie sie.Przyklad II. Tkanine wiskozowa na¬ pawa sie jak w przykladzie I roztworem mocznika dwumetylolowego, suszy, kondy- cjonuje i nastepnie wytlacza na niej wzór za pomoca wyciskarki. Tkanine potem trak¬ tuje sie jak w przykladzie I roztworem chlorku wapniowego, dzieki czemu karbo¬ wanie utrwala sie i uodpornia na pranie. PLThe invention relates to the treatment of yarn, threads, fabrics, fibers or other materials of vegetable origin, e.g. cotton and regenerated rayon made of fiber, with the exception of silk made of fiber esters, and is intended to render these materials resistant to wrinkling, in the course of washing and the action of light, as well as the fixing of mechanical effects on the washing effect. According to the invention, the materials are treated with inert aqueous solutions of the urea-formaldehyde condensation product, and the material is then watered with water. can be treated with cold acidified concentrated salt solution, which has a high affinity for water, but does not cause the fiber to swell. The fibrous material, watered as above, after drying and conditioning, may be subjected to mechanical treatment in order to change the shape of its surface; finally it is treated with a cold concentrated salt solution. In this way, the effects produced by mechanical means, eg notches, moire, glace effect, are fixed without the need to further condense the product by the action of heat. Further condensation proceeds smoothly in the salt solution at ordinary temperature. The salt and its concentration in the solution are chosen such that the fibers at room temperature do not swell at all or only slightly rot. The salt suitable for this process is calcium chloride, used in a solution containing about 600 g of anhydrous calcium chloride per liter. Likewise, magnesium chloride and aluminum chloride can also be used; The concentration of the solution can vary widely, as well as the duration of treatment with the fsQli solution, which is at least a few rhinutes. Good results, for example, are achieved with a calcium chloride solution after about 10 minutes. with a small amount of acid, e.g. 0.1-0.5% hydrochloric acid, or a slightly larger amount of a weaker acid, e.g. acetic acid. The main feature of the invention is the possibility of achieving the results mentioned in the introduction without heat treatment of the textile material. Example I. A mercerized cotton fabric is filled with an aqueous solution of 16% urea. Dimethylol and 0.8% formic aldehyde. This solution is completely inert and does not contain any catalysts. After padding, the fabric is lightly dried and then poured with a cold water. with a solution containing 600 g of anhydrous calcium chloride per liter and 15 cm3 of 28% hydrochloric acid. After padding, the fabric is left to rest folded or rolled for at least 15 minutes, after which it is rinsed with water slightly alkaline with ammonia, and finally soaps and dried. After this treatment, the fabric is much more resistant to creasing. Example II. The viscose fabric is moistened as in Example 1 with a solution of dimethylol urea, dried, conditioned and then embossed on it with an extruder. The fabric is then treated as in Example 1 with a solution of calcium chloride, whereby the carburization is fixed and made resistant to washing. PL
