W przemysle sztucznego jedwabiu mia¬ lo duze znaczenie, szczególnie w poczatko- wem sitadjtun rozwoju tej galezi przemy¬ slu, otrzymywanie wlókien o silnym poly¬ sku, Z biegiem czasu jednak, gd'y sztuczny jedwab zyskiwal coraz wieksze zastosowa¬ nie, pozadane istaly isiie wflókna, które nie posiadalyby duzego polysku, a mialyby ra¬ czej matowy jedwabisty wyglad.Wykonywano szereg prób w tym kie¬ runku. Tak np., wedlug niemieckiego pa¬ tentu Nr 389 394 i patentów dodatkowych sitosowano tak zwana swieza wiskoze, nie¬ dojrzala lub o slabej dojrzalosci alkalicz¬ nej i sitar ano isie otrzymac w ten sposób ma- toWy polysk,. Sposób ten posiada te wade, ze trudne do zachowania w praktyce wa¬ runki tych doswiadczen daja wskutek te¬ go niejednolity produkt koncowy, wzgled¬ nie wykonanie sposobu nie jest latwe.Obecnie stwierdzono, ze mozna otrzy¬ mac matowe przedziwo z jedwabistym po¬ lyskiem, jezeli wlókna, wytworzone zwy¬ klym sposobem, poddaje sie dalszej prze¬ róbce w sposób, stanowiacy przedmiot ni~ nie j szego wynajlazku.W tym celu jedwab przed bieleniem nie zostaje pozbawiony siarki, lecz bieli go sie bezposrednio z zawarta w nim siarka.Dzieki temu na wlóknach wytwarzaja sie koloidalne osady, które zapomoca wy¬ mywania nie daja sie usunac wcale lub z wielka trudnoscia.Otrzymany w ten sposób matowy je-dwaibisty polysk jefst trwaJy, nie znika rów¬ niez przy farbowaniu sztucznego jedwabiu.Sklcttiftoisc soli do wytwarzania koloidal¬ nych osadów moze byc wzmocniona przez roztwór odpowiednich soli przed mydle¬ niem jedwabiu.Przyklad. W zwykly sposób wytworzo¬ na wiskoza — jedwab, po wymyciu i skre¬ ceniu, najlepiej jako matek, jako tak zwa¬ ny jedwab smarowy poddaje sie bez uprzed¬ niego odsiarkowania dzialaniu kapieli bie¬ lacej, zawierajacej 0,01 — 0,15% wolnego chloru. Nastepnie poddaje sie ja dzialaniu kwasnej kapieli, zawierajacej domieszke soli glinowych, magnezowych, cynkowych i podobnych. Konzystnem jest stasowac do kapieli dodatek 1 — 2% soli, obliczonych w stosunku ido objetosci kapieli.Nastepujaca potem obróbka w kapieli mydlanej odbywa sie tak dlugo, az prze¬ dziwo jedwabne wykaze slabo kwasna re¬ akcje. PLIn the rayon industry of great importance, especially in the early stage of the development of this industry, the production of fibers with a high gloss, Over time, however, as rayon gained more and more application, the desired were and fibers which would not have a high gloss, but would have a rather dull silky appearance. Several attempts have been made in this direction. For example, according to the German Patent No. 389,394 and additional patents, so-called fresh viscose, unripe or with poor alkaline maturity, was used and the sieve could not be obtained in this way. This process has the disadvantage that the difficult to practice conditions of these experiments result in a non-uniform end product, or the process is not easy to carry out. It has now been found that a matte appearance with a silky gloss can be obtained. if the fibers produced in the usual manner are further processed in a manner which is the subject of a less leachate, for this purpose the silk is not desulphurized before bleaching, but is whitened directly with the sulfur contained therein. As a result, colloidal deposits are formed on the fibers, which cannot be removed at all or with great difficulty if they are washed away. The matt, smooth gloss thus obtained is durable and does not disappear even when dyeing rayon. Colloidal deposits can be enhanced by a solution of suitable salts before soaping the silk. Viscose - silk produced in the usual way, after washing and twisting, preferably as mothers, as so-called lubricating silk, is subjected to the effect of white bath, containing 0.01-0.15% free chlorine. Then it is subjected to the action of an acid bath, containing an admixture of aluminum, magnesium, zinc and similar salts. It is necessary to add 1 - 2% of salt to the bath, calculated in proportion to the volume of the bath. The subsequent treatment in the soap bath is carried out as long as the silk silk shows a weakly acid reaction. PL
