Definitions
- a process of treating artificial fibrous textile material made from viscose by a regeneration process which comprises contacting them with a caustic alkali solution of not substantially less than 36% strength (calculated as NaOH) at a temperature below 25 C., while allowing such textile material to shrink, and then washing such treated textile material, and drying the same, all without at any time treating such textile material with a solution of a cellulose compound, containing an alkali metal trithiocarbonate.

(Cl. 8-20) In application Serial No. 367,154 filed cOncurof skeins is treated without stretching for one rently herewithis described aprocess wherein valminute with a solution of caustic soda of 50 per uable properties are imparted to artificial silk cent. strength at 15 C.

I have now discovered that, contrary to what Example 3.Artificial silk made by the process might be expected from the aforesaid specificadescribed'in my Patent No. 1,683,199 (namely by tion, caustic alkali solutions of certain concentraspinning viscose into a bath which has a plasticiztions, namely containing not substantially being effect on the thread-like viscose stream during 0 low 36 per cent. of caustic alkali (calculated as or immediately after its coagulation, for instance 0 NaOH) are capable of producing the aforesaid into sulphuric acid of not less than 55% strength) improvement at ordinary or moderate temperais immersed without stretching for one minute in tures, but that the improvement attained at ora caustic soda solution of 50 per cent. strength dinary temperature, for example at 15-25 C. or at 15 C. and then finished as in Example 1 or 2. even at lower temperatures is at least equal to The material will be found to have an extensibil- 25 that attained by a similar treatment conducted ity of 8 to 9 per cent. against 5 to 6 per cent. of at a high temperature with an alkali solution of the same silk in the untreated condition.

My invention is based on this discovery, and The artificial silk preparedin accordance with consists in a process for improving artificial fibers said Patent 1,683,199 (later reissued as No. 18,170) 30 by treating the material with a caustic alkali sois 'what is now commonly known as Lilienfeld lution of at least 36 per cent. strength (calculated silk and is characterized by high wet and dry as NaOH) at a temperature not higher than strengths, i. e. by a dry tenacity of over 2 grams 25 C. per denier (and sometimes 5 grams per denier or If, for example, two samples of artificial silk in even more) and a wet tenacity of 1.5 grams per 35 the form of fiber or fabric artreated respectively denier (and sometimes 2.5 grams per denier or at 15 C.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical efiect, I claim:
1. A process of treating artificial fibrous textile material made from viscose by a regeneration process, which comprises contacting them with a caustic alkali solution of not substantially less than 36% strength (calculated as NaOH) at a temperature below 25 0., while allowing such textile material to shrink, all without at any time treating such textile material with a viscose solution.
2. A process of treating artificial fibrous textile material made from viscose by a regeneration process, which comprises contacting them with a caustic alkali solution of not substantially less than 36% strength (calculated as NaOH) at a temperature below 25 C., while allowing such textile material to shrink, and then washing such treated textile material, and drying the same, all without at any time treating such textile material with a solution of a cellulose compound, containing an alkali metal trithiocarbonate.
3. In the treatment of textile materials made from viscose by a regeneration process, the steps of contacting the same with a solution of caustic alkali of not substantially below 40% strength (calculated as NaOH), at a temperature not substantially above 25' C., and thereafter washing out the alkali.
4. In the treatment of textile materials made from viscose by a regeneration process, the steps of contacting the same with a solution of caustic alkali of not substantially below strength, (calculated as NaOH) at a temperature not substantially above 25 C., and thereafter washing out the alkali.
5. In the treatment of artificial cellulosic threads regenerated from viscose, the steps of contacting the same with a caustic alkali solution of not substantially below 40% strength (calculated as NaOH), in a solvent liquid consisting of water, at a temperature not substantially above 25 C., and thereafter washing out the alkali.
6. A process for treating artificial textile fiber produced by spinning viscose into a bath which has a plasticizing efiect on the thread-like viscose stream during or immediately after its coagulation, for instance into sulphuric acid of not less than strength, said fiber having a dry tenacity. exceeding 2 grams per denier, which comprises contacting them with a caustic alkali solution of not less than 36% strength (calculated as NaOH), in a liquid solvent consisting of water, at a temperature below 25 C., in the absence of a cellulose compound containing alkali metal trithiocarbonate.
V 7. A process as in claim 6, wherein the artificial fibers are treated with the caustic alkali solution while in an unstretched condition.
8. A process for treating artificial textile fiber produced by spinning viscose into a bath which has a plasticizing effect on the thread-like viscose stream during or immediately after its coagulation, for instance into sulphuric acid of not less than 55% strength, said artificial fiber having a dry tenacity exceeding 2 grams per denier,
which comprises contacting the same with a caustic alkali solution of not less than 36% strength (calculated as NaOH) at a temperature below 25 0., then washing the treated artificial fiber, and drying the same.
