Patented May 2, 1950 BROGESS: FGBL OBTAINING TRANSPARENT v EEFEG'IIS N -REGENERA'TED CELLULOSE f FIBERS "Paul Walter Stcinlin; Basel, Switzerland; assignor Aktiengesellschaft Cilander, Herisau, Swit- 1 zenlandi 1N0 Drawing; Application J uly.31,,194'6; Serial No.. (587;5-10: In- Switzerland 'Aprii2'2, 1943 7' Claims 1.
The present application is irr the nature ot a continuation in part as myrearlier copendingi'appl'ication Serial Nol 5233;7882 mean/raw 2; 1 944, now abandoned.
Transparent fabrics; alsm known: as. organdi'es, have as a rule been madefrompurecotton-materials, in particular: muslin, or, more rarely; voile or other finefabrics, suchcambric, etc. Or
gandies of especially" fine quality were made of natural silk.
The process hereafter described relates to the production of plain or patternem smooth:orcrepe transparent fabrics trormmaterials consisti'ngof staplefibre made from regenerated cellulose alone or of staple fibre madefrom: regenerated cellulose and cotton, or o'i' mixed cotton and staple fibre made" from regenerated'rcellulosex Variousexperiments were maderin: the past to transform textiles of this 1 hind by theordinary methods used for' cotton 'fabrl'cs. However. even by varying and. adapting working conditions; such as concentration oi'acidsrand alkaline: swell ihg agents, and the duration: ofthe proceduradt proved impossib e: to turn out marketablevgoo ds. Indeed the materials hithertoproduced were horny, brittle and stiffened. and" in no way. suited forpractical use. The-presentrproc'ess, on the; contrary, produces: transparent. fabrics: which perfectly satisfy a llrecuirements as to: appearance, lustre, softness ami durabilitv; and'zshow a high degreeaoftranscarency combined with aremarkable clearness of weave.
These effects are ohtainediby first treating the fabric with strong, hot alkali, then s b ec ing it to the action of strong, preferably-cold sulphuric acid, and finally again treating it with strong alka i this time cold. The fabric can, eventually, be subjected to a treatmentwith alkaline or acid swelling agents either before or after.
The process is suited for fabrics made ofjpure stapletflbre made" from regenerated cellulose, or woven with cotton andstapleflbre made. from. re.- generated cellulose, and also'i'orthcse woven. with mixedstaple fiber madeifromunegenerateacellu lose and cotton yarn. Naturally, materials in which any or all of the above-combinations are present, either in plain crpattern weave, including "of course applications: wittr'embroideryor Swiss dotted. weave, canalso he .treatedi'bwmy process.
It is advantageous to delubricate and bleach the fabric to be processed. Crude fabrics can, however, be treated in the same way. In this connection it should be borne in mind that, ac-
cording to theinventiomthis processing issuitable for use in any phase of pre treatment.
. My process can be usedto advantage in ccmbirnation with treatment by swelling agents; order and manner in which these treatmentsr are applied depend on the result desired.
In some cases afurther improvement can be achieved by repeating the process wholly orin part.
Treatment with strong sulphuric acid ls-carried out with sulphuric acid of. -52 B. atitemperatures ranging. from --5 to +2(l C. for-"at least 5 seconds.
Treatment with strong, cold alkali is carried out withan alkali of at least 15 B15. attemperatures: ranging from -59 to +25 0. forat least- 5 seconds.
By hot alkali is understood. a treatment acp cording to the present process withhotalkall solution of mercerizing strength, at atempera.- ture of. 25 C. or over, havingadurationof. 5%sec. ends or more.
It is. advantageous to rinse. and neutralize be;- tween acid and alka ineswelling treatments. Between two consecutive alkaline treatments the. question of rinsing and neutralizing.isdecided bythetype of efiectdesired,
Patterned as well as p ain transparent fabrics can be obta ned with the present. processibyap plying suitable. reserves beforethe swelling treatment. For example imago'effectscanbe achieved. by printing with pigments, resulting. in opaque. non-transparent patterns, By this. methodit. is. possible, according to the type of process chosen to. use pigment carriers proof against acid. and. alkaline swellingagents, such as gums or artificial resins, whichresult in local opaque .efiects or non-acidproof thickening agents which produce stifiened. transparent designs in which the efiect of contrast is. due to the pigmentation. alone; It is moreover possible to introduce reservesflduriii any phase of the. transforming processso asto. achievaior example, a. transfaarent efi'ectami then, by rinsing and subsequent. swelling and. shrinking, obtain the. appearance of. crepe. Itiis also possibleto. get intermediary .effectsfby'the. imprint of. swelling agents, and. subsequent treatment with hot. alkali; The reserves-can even; he. applied during various phases of the. process in such away that the transformed material shows untreated and swollen, that is shrunken and transparent areas one next to the other.
It is evident that by printing in colours or by the usenf coloured reserves such efifects can be obtained in various tints.
Fabrics submitted. to the present process can be dyed either before or after treatment. In this way, according to the method of procedure, the most varied results can be obtained, such as plain transparent, or, according to the different aflinity for the dye caused by different local treatment, shaded effects.
My process may be illustrated by means of a single example:
A singed, bleached and tentered fabric made from staple fibre made from regenerated cellulose is treated with NaOH of 30 Be. at 50 C. for 8 seconds, rinsed, neutralized and dried. It is then subjected to the action of sulphuric acid of 45 B. at 15 C. for 7 seconds, neutralized and rinsed. Next comes a treatment with NaOH of 31.B. at 10 C. for 6 seconds. After neutralizing, rinsing and finishing in the usual way, a very fine staple fibre transparent fabric is obtained.
