Definitions
- the object of the present invention is to proza threads or filaments presenting reduced lustre and more particularly threads or filaments presenting a dull matt or lustreless appearance, or of considerably reduced lustre.
- a heated casing or spinning cell such for instance as described in U. S. Patents Nos..l,'602,125 and 1,541,104 and 1,731,317), through which a current of air is caused to pass, a solution containing cellulose acetateor other esters or ethers of cellulose and water.
- the quantity of water present in the spinning solution will vary according to the spinning conditions and the result it is desired to achieve.
- each of the above solutions will yield delustred artificial filaments, the filaments produced from'solutions a or b being substantially completely delustred andpresenting a dull matt appearance, the filaments produced from solutf bf air tions 0 or (2 being very dull'but slightly more lustrous than those produced from solution a or 2), whereas filaments .produced from solution e are only slightly delustred.
- With increasing temperatures of the heated air the degree of delustration imparted to the filaments will decrease, for instance, with a current ofair heated to a temperature of 65 C. solutions a or I) yield slightly delustred filaments, whereas solutions 0 or a! yield bright filaments of but slightly reduced lustre.
- Solution e should not be spun with an air current exceeding temperatures of about 50 to60 0., otherwise the water will not actias a precipitant and highly lustrous filaments will I In performing the invention we preferably wind 1 result.
- the filaments up (continuously withtheir formation) with or without twisting, on apparatus located outside the evaporative atmosphere, though 0 such winding may be performed within said atmosphere if so desired.
- the filaments may be extruded either down wards or upwards into the spinning 'cellor metier casing, and the-air current (which may be caused to pass either upwards or downwards through the metiercasing or cell) may be heated or warmed therein or prior to admission thereto or both before and during passage through the cell or metier casing. Further, the filaments may be extruded in the same direction as 'orcounter-current to the air current.
- the temperature to be employed in the spin-j ning cells or metier casings may vary with the boiling point of the solvents used, the composition of the spinning solutions and the degree of delus- .tration it is desired to produce in the filaments or threads. Such temperatures may be higher or so f lower than theboiling-point or points 01- the solvent or solvents employed. p 1 t ,We have found that with spinning solutions c ontaining the more usual solvents such as acetone;
- methyl acetate or the like,-temperatures of-about to, 80 C. may usefully beemployediin the spinning cells or metier casings, but we in no way limit our to such temperatures.
