Definitions
- This invention relates to antistatic cospun yarn comprising poly(hexamethylene adipamide) filaments and poly(ethylene terephthalate) filaments and to woven and knitted fabrics made therefrom.
- the nylon 6,6 filaments contain from about 3 to 10 weight percent of an N-alkyl substituted polycarbonamide modifier in which the tertiary carbonamide groups are an integral part of the polymer molecule.
- Useful modifiers are those disclosed in Alderson U.S. 3,900,676.
- the modifier has a molecular weight of at least about 800 to 5000 and is dispersed throughout the filament substantially as a separate phase in the form of discrete elongated conductive particles aligned essentially parallel to the filament axis, all as described in the aforementioned Alderson patent.
- the elongated conductive particles should have a ratio of their length, L, to average diameter, D, of at least about 100 as taught in said Alderson patent.
- the N-alkyl polycarbonamide may be mixed directly with the fiber-forming nylon 6,6 and then immediately spun into filaments. If desired, it may be combined with polymer flake and then spun into filaments. Less reactive N-alkyl polycarbonamides can be introduced into the autoclave during production of the fiber-forming polycarbonamide. Preferably, the N-alkyl polycarbonamide and fiber-forming nylon 6,6 are mixed in molten condition and immediately spun into filaments.
- the cospun yarns of the examples which follow were prepared using the general procedures described in the aforementioned Reese patent.
- One filament group of the mixed filament yarn was 2GT filaments while the other was nylon 6,6 filaments, the latter having incorporated therein the antistat modifier mentioned above.
- Two techniques for incorporation of the N-alkyl substituted polycarbonamide are illustrated.
- the modifier was injected into the nylon 6,6 stream shortly before extrusion by injection of the modifier into the screw melter-extruder and mixing before the melt-spinning operation.
- Example II the modifier was combined with the nylon 6,6 in the autoclave in the polymerization cycle.
- cospinning is achieved by separately metering 2GT and nylon 6,6 containing modifier to two separate inlet ports of a melt spinning assembly designed to accommodate the two streams and keep them separate.
- the polymers are discharged in a conventional manner through a spinneret.
- the two groups of filaments merge and are then drawn and wound up in a package. Details are given in the examples.
- Skein Log R - this test is similar to the yarn log R test in U.S. 3,900,676 except that for Skein Log R, sufficient revolutions were wound to make a skein with a cross-section of 720,000 denier.
- the skein is scoured, dried and conditioned at 20% relative humidity for 24 hours.
- the skein is cut and clamped without spreading between electrodes 2.0 inches apart so that 360,000 denier is between the electrodes.
- the resistance is measured at 20% relative humidity with a megohmeter under a potential of 210 volts.
- Cospun yarns of trilobal 2GT filaments (60% by weight) and trilobal nylon 6,6 filaments (40% by weight) containing antistat modifier were prepared from nylon 6,6 (42 R.V. with 0.02% Ti0 2 ) containing 4.6% by weight of modifier and from 2GT (22 R.V. with 0.1% Ti0 2 ).
- the polymers were melt spun at 291°C through a single spinneret into a yarn (6 filaments of each polymer) in which the nylon 6,6 filaments had an R.V. of 47.7 and the 2GT filaments an R.V. of 21.5.
- the extruded filaments were air-quenched.
- Example II A process similar to that used in Example I was performed except that the polymers used were nylon 6,6 (32 R.V. with 0.02% Ti0 2 ) containing 5.25% by weight of modifier and 2GT (22 R.V. with 0.1% Ti0 2 ).
- the resulting yarn was made up of nylon 6,6 filaments (40% by weight) of 39.5 R.V. and 2GT filaments (60% by weight) of 21.2 R.V.
- the yarn denier was 40, percent elongation was 42.5, and tenacity was 3.5 gpd.
- the antistatic performance of the yarn and the performance of warp knit fabrics of such yarns is reported on Table I as Item 2.
- Item 3 of Table I represents a cospun trilobal control yarn containing no antistat modifier, but is otherwise similar to Items 1 and 2.
- Items 4, 5 and 6 are commercial warp knit fabrics from 40 denier yarn.
- Item 4 is a trilobal nylon antistatic 13-filament yarn.
- Item 5 is a quadralobal nylon antistatic 20-filament yarn and
- Item 6 is a round nylon 13-filament yarn containing no antistat.
- Items 4 and 5 contain the same modifier as used for Item 1 and at a concentration of 5.25%.
- Item 7 and 8 represent experiments performed to compare results obtained from nylon 6,6 yarns in which modifier 5.25% concentration was added to 100% of the filaments (Item 7) and nylon 6,6 yarns in which modifier was added at 5.25% concentration to only 50% of the filaments (Item 8). In each case the same modifier was used.
