Abstract:
A moldable acoustic facing comprises cellulosic fibers and synthetic fibers entangled together. The acoustic facing has a basis weight of from about 1.5 to about 5.0 ounces per square yard (osy), a thickness of less than about 0.050″, a mean pore size of between about 8 microns and about 40 microns, and an elongation at break of at least twenty percent. The acoustic facing includes less than about five percent synthetic microfiber and has an acoustic resistance of at least about 250 Rayls.
Abstract:
The present invention provides a tunable sound absorption facing which includes a cellulosic web and a nonwoven web entangled together. The facing has a controllable air flow resistance.
Abstract:
An absorbent mat includes top and bottom layers of thermoplastic material with absorbent media disposed therebetween. The top and bottom layers are bonded directly together, or to the absorbent media disposed therebetween, in spaced-apart bond sites. One or more perforations are formed as a result of bonding in the top and/or bottom layers in a peripheral portion of each bond. Each perforation is in communication with the absorbent media and provides a pathway through which liquid can pass. The top and bottom layers may be monolithic thermoplastic film with an aperture formed therethrough at each respective bond by stretching the multi-layer absorbent mat. One or more perforations are formed in the peripheral portion of each bond site thereof as a result of stretching. Each perforation is in communication with the absorbent media and provides a pathway through which liquid can pass into the absorbent media.

Abstract:
A concrete curing blanket includes a layer of absorbent material and a layer of impervious material bonded to the absorbent material layer in face-to-face relationship at intermittent locations such that the impervious material layer between the intermittent locations can lift away from the layer of absorbent material in response to air bubbles rising through the layer of absorbent material. The intermittent bonding locations may take the form of a pattern or may have a random occurrence. The absorbent layer of material is a hydrophilic nonwoven fabric and the impervious material layer is a film.
Abstract:
An absorbent, non-skid drop cloth includes a lofted, non-woven fabric layer, and a non-skid barrier layer bonded to the non-woven fabric layer, wherein the barrier layer reduces slipping of the drop cloth on floors and other surfaces. The non-woven fabric layer has an absorbent capacity of greater than five hundred percent (500%) and a basis weight of less than five ounces per square yard (5 osy). The barrier layer includes polymeric film.
Abstract:
An acoustic panel includes a main body portion having a substantially planar front surface for orientation toward a sound source and an opposite, substantially convoluted rear surface. An airflow-resistive layer of material is secured to the planar front surface in face-to-face contacting relationship. The airflow-resistive layer of material may have a specific airflow resistance of between about 50-20,000 mks rayls, and may be configured to attenuate sound at one or more predetermined frequencies. A depth of convolution of the rear surface is between about forty percent to about seventy-five percent (40%-75%) of a thickness of the main body portion.
