Definitions
- This invention relatesto the manufacture of artificial filaments and threads from solutions of cellulose acetate or other cellulose esters of organic acids, by the evaporative method, that is to say wherein such solutions are spun as filaments, into the air and the filaments solidify by evaporation of solvent carried by them. the solidified filaments are associated together as threads in their spinning jets or nozzles.
- the solutions employed for evaporative spinning of cellulose derivatives such as referredto are made with volatile solvents such for example as acetone, alone or associated with higher boiling solvents.
- volatile solvents such for example as acetone
- solutlons by reason of the boiling points of the solvents used and of the rapidity with which the spun,- have' to be extruded into a current of eated air. It has been found that filaments so roduced may tend to vary considerably from roundness of section and to or turn woolly under the action 209,125, corresponding to U. S. application 641,7 60, filed May 26, 1923, I have proposed relatively low temperature may temperatures,
- Iv may employ solvents of very low boiling point, which in associa tion in suflicient proportion with volatile non-solvents will allow of producing the artificial filaments or the like at relatively low temperature or at about ordinary room temperature.
- I may employ as solvents very low boiling liquids such as acetaldehyde or formaldehyde or, mixtures thereof, and as non-solvents liquids such as alcohol, benzol and so forth, or, though with less advantage, water or mixtures. thereof with such non-solvent, liquids.
- I- may employ in particular mixtures of or containing a very low boiling solvent suchas acetaldehyde or/and for-- maldehyde and a volatile non-solven'tsuch as alcohol. 4
- While the invention aims more particularly to effect the evaporative spinning at about, ordinary temperature by employment tion of non-solvent of acetaldehyde and acetone,
- I may employ acetone, or mixtures in association with alcohol or like volatile non-solvents for the evaporative spinning of cellulose acetate filaments or the like.
- the solvents'and non-solvents may be employed in any suitable relative proportion to give the effect hereinbefore referred to, that is to saythe development of a precipitating or incipient precipitating action on the cellu- "required, and conversely the lower'the viscosity 'of the cellulose derivative or' derivatives in a mlxture of given concentratlon,
