Definitions

• This invention relates to the treatment .of threads of spun filaments of cellulose acetate or fabrics containing them and more especially to a process for impartin to the cellulose acetate materials a woo ly appearance and feel and/or special appearance.
• Another object of this invention is to provide a method comprising treating the cellulose acetate fibers with anaqueous solution containing a chloride preferably of light metal such as magnesium, calcium or lithium prior to the treatment with the hot dilute acid solutions.
• a chloride preferably of light metal such as magnesium, calcium or lithium
• I subject the cellulose acetate fibers, threads or yarns or fabrics containing said fibers to an aqueous solution containing a chloride and then subject the treated materials to the action of a boiling solution dilute acid.
• the chlorides which I have found to give very satisfactory results are the chlorides of calcium, magnesium and lithium. These chlorides may be used in varying concentrations. I, however, prefer to use a 10%3 0% concentration, since this concentration glves most regular and uniform results.
• the cellulose acetate material is treated with the aqueous chloride solutions at ordinary tempera-- ture from 2 to 24; hours depending on the degree of torsion of the thread or the tightness of the weave of the fabric. The hlgher the degree of torsion or the tighter the weave of the fabric the longer must be the subjectlon to the aqueous chloride bath. If the cellulose acetate were at this stage of the process washed without tension free from the chloride, it would possess the characteristic glossy appearance and feel of the original fabric.
• naphthalene-sulhonic, anthranilic, pyrogallic and'the like he concentration of the acid should not (ex ceed 1/10 of the normal concentration and when the cellulose acetate is subjected there- 5 to, it should be at its boiling temperature.
• the concentration of the acid should not exceed N/ 10. This is true with respect to mineral, inorganic or organic acids.
• the concentration thereof may be less thanthat used with mineral acids. I have "found that a concentration of N/ 100, or even less in the case of organic acids, produces sat isfactory results.
• the cellulose acetate may be subjected to the boiling aqueous acid solutions for various times. I have found that 1 to 20 minutes is generally sufficient to accom plish the desired results.
• Hydrochloric acid has a detrimental influence oncotton and viscose fibers and accord-' ingly it should not be used in treating fabrics containing such fibers.
• the method and apparatus employed in the above treatment may be of any well known type.
• Ewam le [.A fabric with a satin weave comprisln a cellulose acetate silk warp and a cotton we t is, after desizing, immersed for 12 hours in a 30% aqueous solution of calci um chloride. After the removal of the. excess material the fabric is treated for 20 minutes in a boiling N/lO boric acid solution. After this treatment the fabric is rinsed and dried. The fabric treated in this manner has .acquired a peculiar dull mother-of-pearl-like appearance and has not sacrified any of its desirable properties.
• Example II..A velvet with an acetate silk pile is immersed for 4 hours in a 20% solution of calcium chloride. It is then immersed in. a
• the velvet so treated has a dull aparance and this dullness persists even after yeing by any of the usual methods and dyes for mixed fabrics containing cellulose acetate silks.
• Ewample III A crepe havin natural silk .warp and acetate silk weft, is, a ter desizing, immersed for 24 hours in a 10% calcium chloride solution. After the removal of the excess of calcium chloride solution it is treated for 15 minutes with a' boiling N /100 betanaphthalene-sulphonic acid solution. A crepe so treated acquires a very regular dull appearance and has an extremely supple andwoolly feel. It can be dyed by'any of the usual methods.
• Example V One kilogram of acetate silk is immersed for 8 hours in an aqueous solution of 20% calcium chloride. The excess solution is removed in air'by any of the usual and well known methods. After this treat-' ment it is immersed for 15 minutes in a boiling N /20 solution of pyrogallic acid. After this treatment it is washed or rinsed with water. Finally after the removal of the excess water, it is dried in a stream of hot air at approximately 70 C. Silk treated in this manner becomes matt and acquires a fawn shade similar to the wool of the angora goat or similar to camels hair.
• a fabric so treated has a slightly matt appearance. It has also acquired the a pearance. of a cloth woven with raw sil hke tussah silk.
• N o de-acetylation of the fibers takes place during the treatment.
• the process is especially important from an economical polnt of new. Apart from the fact that a smaller amount of material is used, due-to the fact that the acid bath is very dilute,.the loss of the acid by evaporation and the emanations of the It is furthermore obvious that acids are reduced to a minimum.
