Definitions
- the artificial fibre when subjected to the treatment hereinafter described, undergoes an action similar to the action produced on depilated skins when subjected to chrome tanning with one or two immersions, which acquire great tenacity and powerful resistance to stretching and are not affected by boiling water.
- the treatment which is covered by this invention and can be used in the actual manufacture of artificial fibres formed of or containing protein-like substances, is based on the use of salts of chromium (chrome alum, chromium sulphate,
- the treatment may be effected with two baths, the first containing for example sodium or potassium bichromate and the other containing products capable of converting the compounds of chromic anhydride into compounds of chromium sesquioxide.
- Example 1 Artificial fibre prepared from casein is impregnated in a bath containing grams per litre of potassium bichromate with the addition, if desired, of a mineral acid. After the impregnation of the fibre it is squeezed and placed in another bath containing 100 grams per litre of sodium bisulphite and then thoroughly washed with water. The fibre so treated acquires all the properties above mentioned (better resistance to stretching, wear, boiling water, etc.).
- Example 2 Artificial fibre treated as in Example 1 is dyed with chrome dyes by the afterchroming process as well as in the dyeing process with a single bath.
- the alkaline iulling of the dyed material does not exercise any negative influence upon the shade and the resistance of the fibres, whilst similar dyeings executed on untreated fibre are practically unusable after having been subjected to alkaline fulling.
- Example 100 parts or casin staple fibres are treated in a milling drum during minutes with a 30-40" C. warm solution of 8.10.D ,s of sodiumor potassium bichromate in 400-500 parts of water.
- the textile materlaltreated and dyed according to the example possesses a much better touch and better dynamometric properties as compared with the material that has not been subjected to the tanning operation.
- Example 7 100 parts of casein yam are treated during 18 hours at ?"C. in a solution of the following composition:
- the casein fibre which is colored in a clear olive green shade possesses a smooth touch which remains, even after a subsequent dyeing in a bath containing mineral acid.
- the resistance to breaking and the elasticity of the casein fibre treated in this manner is much better as compared with the casein fibre which has not been subjected to the above treatment.
- a process for producin water-insoluble artificial casein fiber which comprises the steps of impregnating hardened fiber, prepared from a casein solution by a spinnin and hardening process, with a solution of a water-soluble chromium'compound, and then converting the latter,
- a process for producing water-insoluble artificial casein fiber which comprises the steps of impregnating hardened fiber, prepared from a casein solution by a spinning and hardening process, with a solution of a water-soluble salt of chromic acid, and then converting the latter into a water-insolubble chromium compound by treatment of the impregnated fiber with a reducing agent, thereby causing the formation and fixation of the water-insoluble chromium compound in and on the treated fiber.
- a process for producing water-insoluble artificial casein fiber which comprises the steps of impregnating hardened fiber, prepared from acaseln solution by a spinning and hardening process, with a solution of a water-soluble salt 'of chromic acid, and then treating the impregnated fiber with a solution of a reducing agent.
- a process for producing water-insoluble artificial casein fiber which comprises the steps of impregnating hardened fiber, prepared from a casein solution by a spinning and hardening process, with a solution of an alkali metal bichromate, and then treatin the impregnated fiber with a solution of an alkali metal bisulphite.
- Water-insoluble artificial casein fiber comprising an insolubilized fiber body prepared from a casein solution by a spinning and hardening process, and containing a subsequently-incorporated water-insoluble chromium compound in and on said fiber body, said fiber possessing improved dynamometric resistance and improved fastness to boiling water, milling, washing and dyeing, as compared with the same insolubilized artificial fiber free from said water-insoluble chromium compound.
