Definitions

• the principal object of the present invention accordingly is to provide a simple and efficient process for the production of transparent cotton and cellulose-containing material which,
• the concentration above the critical value can be varied within wide limits. Sulfuric acid with gravity between 51 and 54 Be. is-particularly useful. The temperature of the acid should always be maintained so that it lies below C. during the treatment. When the temperature is minus 5 C. the effect becomes quite noticeable. Very favorable temperatures are those around minus (2., although further temperature variations within the range below the zero mark are permissible.
• acid at low temperatures assures that hydrolytic decomposion of the fiber is inhibited and the fiber is thereby preserved.
• certain substances may be incorporated in the sulfuric acid as stabilizers, for example pyridine, its homologues and derivatives, monoor polyvalent alcohols, ammonium salts, formaldehyde and formaldehyde. producing compounds.
• the fibrous structures may be subjected to the treatment without previous preparation or else they may be submitted to a suitable prior treatment by mercerization with caustic alkali or by bleaching.
• the acid-treated fabrics may be suitably subjected to a mercerizing after-treatment by mercerization with caustic alkali.
• the after-treatment is especially adapt ed to fabrics that have been given a prior mercerizing treatment with caustic alkali.
• the effects obtained by such treatment may be localized, that is, confined to certain limited portions with a view to producing patterns.
• pattern effects can be obtained in which an outstanding characteristic is that the transparent and opaque undertreated portions resemble one another very closely in their feel, possessing nearly the same soft and supple characteristics.
• Fibrous structures refined in accordance with the new process here disclosed may be submitted to any dyeing and color-printing processes.
• Bleached mercerized fine cotton batiste is drawn for 8 seconds through a bath of sulfuric acid of 52 B., kept at a temperature of minus 10 C. (measured at an outside temperature of C.) and is immediately rinsed. Next the fabric while still wet is mercerized-by caustic soda while tensioned (tautened or tentered) then washed and dried in the jigging frame (Riittelspannrahmen).
• Bleached 'mixed fabric containing cotton and viscose is subjected to the action of sulfuric acid of 54 B. (measured at plus 15 C.) for 7 seconds at a temperature of minus 8". C. and is immediately thereafter washed to free it of all acid. Dryingis effected in a tenter.
• Resist-printed cotton muslin is caused to pass for 15 seconds through sulfuric acid of 51 B. (measured at plus 15 C.), at a temperature of minus 12 C. After squeezing out the liquid there the material is immediately washed with cold water and is then mercerized with soda lye. The material freed from alkali may 2.
