<p>Dryer-activated fabric softening articles having improved spun-bonded polyester substrates having improved feel characteristics as compared to conventional polyester substrates and/or feel characteristics that are not significantly different from conventional rayon substrates, after use in an automatic clothes dryer, said articles comprising: (A) at least about 5 % fabric conditioning composition comprising fabric conditioning active; and (B) a polyester non-woven fabric substrate prepared from a polyester fiber having a denier of from about 2 to about 6, said substrate having a basis weight of from about 0.52 oz/yd2 to about 0.58 oz/yd2, a thickness of from about 0.16 mm to about 0.22 mm, and, preferably, a tear strength of at least about 3 lbs/in2, preferably from about 4 to about 7 lbs/in2 in the cross direction and from about 3.1 to about 6 lbs/in2 in the machine direction, and 'belt fuzz' and 'jet fuzz' grades, as described herein, of from about 1.8 to about 2.9, preferably from about 2 to about 2.7, more preferably from about 2.2 to about 2.5, said polyester having improved feel characteristics as compared to conventional substrates of this type, after said article is used in said automatic clothes dryer and after said fabric conditioning composition has been substantially completely removed from said substrate.</p> |
