20080307583 | Foam with green tea additive for foam mattresses, pillows and cushions - A method of making foam imparts antimicrobial and antiodorant qualities to the foam. Green tea powder is added to the polyol raw materials for making memory foam. The green tea memory foam is used to make pillows, cushions and mattresses. Green tea foam in the top layer of a mattress acts as an antiodorant such that less of the chemical smell of the memory foam is perceived by the user. In addition, the bacteria and mold that would otherwise develop in the moist warmer sleeping environment on memory foam are killed by the green tea additive to the foam. Measurable antimicrobial and antiodorant qualities in the green tea foam are achievable by adding green tea powder constituting less than 2% of the weight of the resulting green tea foam. | 12-18-2008 |
