    Abstract: The invention is a heat curable extruded adhesive laminate system for producing collapsible tanks. The laminate is a composite of a fabric; an extruded linear hydroxyl adhesive having an uretdione that serves as a latent thermally activated curing component, and a high cyrstallinity thermoplastic polyurethane. In the system, panels cut from the adhesive laminate are assembled and seamed in a compression press operating at about 260° F. to about 350° F. The bonding process takes about 20-45 minutes, which causes the latent thermally activated curing component to cure the adhesive. Following compression heating in the press, the resulting seams have a strength that exceeds the minimum acceptable performance of 25 lbs/in, after being immersed in water and/or fuel at 160° F. for six weeks.

    Abstract: The invention comprises a flexible adsorbent-loaded filter formed from a flexible support web and attached adsorbent particles. The adsorbent-loaded filter has open filter cells which are defined by the support web and the attached adsorbent particles and are random in size and orientation through the length and depth of the filter. The support web is formed of substantially nonlinear filaments that randomly intersect. The adsorbent particles largest average cross sectional dimension is smaller than the average diameter of the pores of the support web. When the flexible adsorbent loaded filter is flexed about a radius of curvature 20 mm, the percent increase in pressure drop is less than 100 percent when measured at a face velocity of 0.25 m/s.

  • Patent number: 6716777
    Abstract: A fabric structure is constructed having a fabric base sheet, a viscidity layer, a polymeric back layer, and a protective layer. The polymeric back layer is prepared from SBC (styrenic block copolymer) for the advantage of low specific gravity and preventing the drawback of PVC or the like that pollutes the environment when disposed off. The protective layer is prepared from PU series or modified SBC (styrenic block copolymer) series agent. When the fabric structure used to make a bag, the front surface of the fabric base sheet is disposed outside the bag and the surface of the protective layer is disposed inside the bag.

  • Patent number: 6692825
    Abstract: A nonwoven web and method of preparing a novel nonwoven web of synthetic fiber are disclosed. An aqueous solution amide crosslinked synthetic precursor polymer is extruded under defined conditions through a plurality of die orifices to form a plurality of threadlines. The threadlines are attenuated with a defined primary gaseous source to form fiber under conditions of controlled macro scale turbulence and under conditions sufficient to permit the viscosity of each threadline, as it leaves a die orifice and for a distance of no more than about 8 cm, to increase incrementally with increasing distance from the die, while substantially maintaining uniformity of viscosity in the radial direction, at a rate sufficient to provide fiber having the desired attenuation and mean fiber diameter without significant fiber breakage. The attenuated threadlines are dried with a defined secondary gaseous source. The resulting fibers are deposited randomly on a moving foraminous surface to form a substantially uniform web.

  • Patent number: 6537931
    Abstract: A coated fabric having desirable weight and high durability, and particular utility in the manufacture of linings for particular articles is described. The fabric has a textile substrate which is coated to provide a structure having an abrasion resistance of at least about 750 cycles to failure when tested according to ASTM D 3884, and more preferably at least about 2200 cycles to failure. The coating is desirably transparent so that the pre-coated shade of the textile substrate is altered less than about 15%, and more preferably less than about 1%, when the fabric is coated. More particularly, the absolute value of the difference in shade depth of the coated fabric and the textile substrate is less than about 0.2, so that no visible shade change results. A method for producing the fabric and articles incorporating the fabric are also described.
