Abstract
A laundry conditioning product and method of making the product. The product employs a substrate of non-woven polypropylene or other polyolefin non-woven fabric having a water absorption capacity of less than 400%. The substrate is impregnated with a softening and conditioning composition including one of the di-long chain alkyl, di-short chain alkyl ammonium salts or cationic imidazolinium salts. The laundry conditioner works in a conventional dryer. The weight ratio of the clothes conditioner impregnating the fabric to the non-woven substrate is in the range of 2:1 to 0.5:1. The substrate is arranged in a butterfly configuration including a plurality of sheets bonded together along a substantially centrally located line with the edges of the sheets being free from each other.
