Definitions
- This invention relates to the method of manufacturing artificial silk, which consists in pressing out fibroin solution for spinning intermingled with alkyl ester or alkyl salts, into salt solution or acidic solution from a nozzle.
- the object thereof is to regenerate silk yarn of excellent quality artificially by keeping the original solution thick and viscous, that is, in good condition for spinning, without destroying the fibroin substance excessively even after the lapse of time.
- the main object of my invention is to provide a method of manufacturing artificial silk of excellent quality, uniformity and durability.
- silk fibre or fibroin is dissolved in an alkaline solution containing a metal such as copper, nickel, etc., and the solution is rendered more fluid by various means reducing its viscosity in order to avoid the excessive decomposition of the fibroin with the passing of time, which renders it impossible to spin it on an industrially large scale as regenerated silk. Even if spun and coagulated, it cannot be elongated finely during coagulation and the product has inferior quality with defects in tensile strength, denier size and lustre.
- the present invention it is possible to regenerate silk yarn of superior quality on an industrially large scale, removing the above defects by intermingling methyl acetate, amyl acetate, ethyl acetate and propyl acetate and other alkyl esters of formic acid, oxalic acid, citric acid, tartaric acid and acetic acid or the chloride with the original solution for spinning which has silk fibre dissolved therein.
- alkyl ester as for example, methyl acetate, amyl acetate, ethyl acetate and propyl acetate
- solvent for silk fibre prepared by dissolving copper hydroxide and nickel hydroxide in caustic alkali solution with the addition of one or two of glycerin, glycol, sodium potassium tartr-ate and sugar and then proceed to dissolve fibroin in the solvent 'containing the alkyl ester thus prepared so as to form the desired solution which is of suitable 1.
- a spinning liquor for artificial silk comprising a solution of fibroin in an alkaline solution of a metallic compound of the class consisting of copper and nickel hydroxides with an alkyl ester of the class consisting of methyl acetate, amyl acetate, ethyl acetate and propyl acetate and containing an added organic compound consisting of glycerine.
- the method of preparing a spinning liquor for artificial silk which consists in mixing an alkaline solution of a metallic compound of the class consisting of copper and nickel hydroxides with an alkyl ester of the class consisting of methyl acetate, amyl acetate, ethyl acetate and propyl acetate and dissolving fibroin in the resulting solution.
- a spinning liquor for artificial silk comprising a solution of fibroin in an alkaline Solution of a metallic compound of the class consisting of copper and nickel hydroxides with an alkyl ester and glycol and tending to promote the viscosity of the solution.
