Abstract:
A fabric handling apparatus includes a layup table (20), a mold (22) disposed adjacent to the layup table (20), and a fabric handling array (34) suspended above the layup table (20) and the mold (22). The fabric handling array (34) is adapted to transfer at least one fabric shape (62) from the layup table (20) to the mold (22). The fabric handling array (34) includes a plurality of attractors (36) in an attractor array. An orientation of the fabric handling array (34) is alterable with respect to at least one of the layup table (20) and the mold (22) so that the at least one fabric shape (62) is positionable on the mold (22) in a predetermined orientation.
Abstract:
Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.

Abstract:
The present invention relates to a system and method of bonding garments with elastomers and particularly to a system and method to cut and hem in a garment in a continuous process and also a system and method to incorporate an elastic strip into a garment in a continuous process and a system and method to provide computer control of hemming, bonding, gathering and inserting an elastic strip into a garment.
Abstract:
The present disclosure relates to a textile treatment and the treated textile, wherein one side of the textile is treated to have hydrophobic characteristics and the other side is treated to have both hydrophobic and oleophobic characteristics. The present treatment is wash-durable and breathable. The textile treatment is effective at repelling aqueous liquids (such as rain) and at preventing the penetration of oily liquids (such as chemical warfare agents) through the textile.
Abstract:
The invention provides a water blocking tape for use in a variety of cable designs, such as power cable, data communications cable and telecommunications cable. A water blocking tape according to the invention includes layers of lightweight nonwoven fabric with one or more swellable water blocking compounds, such as water absorbent polymers, disposed between the layers. The nonwoven fabric layers are bonded in a pattern using an ultrasonic bonding technique. The bonding pattern helps to contain and to restrain movement of the water blocking compounds between the layers. The bonding pattern compartmentalizes the water blocking compounds to prevent pooling of the compounds and to facilitate a substantially consistent distribution of the compounds between the layers such that when a tape contacts water, the tape achieves a substantially consistent swell height. A substantially consistent swell height permits a tape to serve as a reliable water barrier to prevent damage and degradation of a cable and its components. Ultrasonic bonding of the multilayer tape eliminates the need and use of adhesives and bonding agents to form the tape that can have inhibiting effects on a swelling action of the tape.
Abstract:
The invention relates to a heat-insulating material (1) acceptable for use, such as a bed blanket. The heat-insulating material (1) has a reinforcing layer, a base layer (10) bonded to the reinforcing layer, and flock fibers secured to the exposed surface of the base layer through a discontinuous coating of cured adhesive (A). The base layer (10) can have a thickness of less than 0.0625 inch. The flock fibers (F) can have a diameter in the range from about 3 denier to about 4 denier. The invention also relates to a method of making the heat-insulating material (1) by providing a laminate of a reinforcing layer and a base layer (10) of a thickness less than 0.0625 inch, wherein the reinforcing layer (11) and the base layer (10) are permanently united to each other; providing an adhesive (A) of a viscosity such that when applied to the exposed surface of the base layer (10) it will remain on the exposed surface without substantial spreading or penetration into the base layer (10) to any substantial depth; depositing the adhesive (A) on the exposed surface of the base layer (10), with a printing roll having a discontinuous surface, in the form of a discontinuous coating; and distributing flock fibers (F) evenly over the discontinuous adhesive coating before the adhesive (A) sets.
