摘要:
The present invention relates an acoustical insulation material for sound attenuation containing a nonwoven web. Surprisingly, it has been discovered that an acoustical insulation material made from a nonwoven web of thermoplastic fibers having an average fiber diameter of less than about 7 microns, wherein the acoustical insulation has a thickness less than about 3 mm and a density of greater than about 50 kg/m3 is effective as a sound insulation material. The acoustical insulation is very effective as an acoustical insulation material, despite the low thickness and high density of the acoustical insulation. A method of attenuating sound waves passing from a sound source area to a second area using the acoustical insulation material is also disclosed.

摘要:
A container liner, shelf liner or drawer liner that will absorb liquids spilled or leaked into a container or onto a shelf or drawer. The liner is a layered product having a layer which is impervious to liquids and an absorbent layer. The absorbent layer further contains a material which is capable of controlling odors, such as those odors found in refrigerators and waste receptacles. The liner of the present invention provides the benefit of absorbing spills and controlling odors in containers such as refrigerators and waste receptacles.
摘要:
The present invention relates to an insulation article having a core of an insulation material encased within a fabric material. The fabric material is prepared from thermoplastic fibers having an average fiber diameter less than about 12 microns. Examples of the fabric material include woven, knit or nonwoven materials. The insulation material may be any conventional insulation material, including foams and fibrous materials. Examples of uses for the encased insulation material of the present invention include architectural applications such as attics, basements and crawl spaces in homes, commercial buildings and in heating, venting and air conditioning systems (HVAC), around appliances, such as dishwashers, refrigerators, clothes washing machines and the like, in vehicles such as cars, trucks, trains, airplanes and the like.

Wet and dry wipes comprising additives for removing allergens from surfaces are disclosed. The wipe substrate comprises an additive capable and binding the allergen onto the substrate such that the allergen can be removed from the surface. Various allergens including animal and pet dander can be removed from numerous surfaces utilizing the wipes of the present invention. In some embodiments of the invention, the allergenicity of the allergen is also reduced. Suitable additives for immobilization onto the wipe substrate include lectins, proteases, and enzyme inhibitors.

Novel skin cleansing formulations are disclosed herein. The formulations comprise an anionic particles, microfibers, or compounds which dislodge contaminants from skin through electrostatic interactions. The anionic particles, compounds, or microfibers can easily be incorporated into various products for improved skin cleaning and removal of the contaminant from the skin. The anionic particles do not necessarily kill microbes on the skin, but dislodge them from the skin surface such that they and other contaminants can easily be removed away from the skin by a substrate.
