Abstract
Provided is batting that includes a bonded nonwoven web made from a fiber mixture containing: (a) 20 to 55 wt % of siliconized fibers having a denier of 1.5 to 10.0 and a length of 51 mm to 84 mm; (b) 10 to 45 wt % of hollow conjugate fibers having a spiral crimp, and having a denier of 1.5 to 10.0 and a length of 51 to 84 mm; (c) 10 to 45 wt % of a first population of binder fibers which are elastomeric co-polyester binder fibers having a denier of 1.5 to 8.0, a length of 51 mm to 84 mm, and a bonding temperature of 110° C. to 180° C.; and (d) 1 to 20 wt % of a second population of binder fibers, which have a denier of 1.5 to 6.0, a length of 51 mm to 84 mm, and a bonding temperature of 80° C. to 135° C.
Claims20
Batting comprising a bonded nonwoven web, said batting having a first surface parallel to a second surface, and said bonded nonwoven web comprising a fiber mixture containing, based on the total weight of the fiber mixture:
- (a) 20 to 55 wt % of siliconized fibers having a denier of 1.5 to 10.0 and a length of 51 mm to 84 mm;
- (b) 10 to 45 wt % of hollow conjugate fibers having a spiral crimp, and having a denier of 1.5 to 10.0 and a length of 51 to 84 mm;
- (c) 10 to 45 wt % of a first population of binder fibers, said first population of binder fibers being elastomeric co-polyester binder fibers having a denier of 1.5 to 8.0, a length of 51 mm to 84 mm, and a bonding temperature of 110° C. to 180° C.;
- and
- (d) 1 to 20 wt % of a second population of binder fibers different from the first population of binder fibers, said second population of binder fibers having a denier of 1.5 to 6.0, a length of 51 mm to 84 mm, and a bonding temperature of 80° C. to 135° C.;
- wherein fibers in the fiber mixture are homogenously mixed.
