Abstract
This invention relates to the production of durably liquidproof laminates and articles made therefrom, the laminates incorporating a barrier layer and a textile made from a composite yarn containing a core including fiberglass as a strength component and a sheath of a different material around the core. Shelters and other protective articles incorporating this laminate are also described.
Claims57
An article comprising
- a laminate that is liquidproof after 10,000 flex cycles and has a weight of about 15 oz/yd2 or less, comprising
- at least one barrier layer;
- and
- at least one textile layer weighing less than 5 oz/yd2, comprising yarns having a core comprising fiberglass and a sheath comprising one or more continuous or staple filaments comprising a second material around said core, bonded to the at least one barrier layer.

An article comprising
- a laminate that has a weight of about 15 oz/yd2 or less comprising
- at least one PTFE barrier layer;
- a polyurethane adhesive;
- and
- at least one textile layer consisting essentially of yarns having a core comprising fiberglass and a sheath comprising one or more continuous or staple filaments comprising a second material around said core, bonded to the PTFE barrier layer by the polyurethane adhesive,
- wherein the laminate maintains its resistance to permeation of chemical vapors after 10,000 flex cycles.
3 more elements
An article comprising
- a first laminate panel and a second laminate panel, each said laminate panel having a laminate weight of about 15 oz/yd2 or less comprising at least one barrier layer and at least one textile layer consisting essentially of yarns having a core comprising fiberglass and a sheath comprising a second material around said core bonded to the at least one barrier layer;
- and
- at least one liquidproof seam joining together the at least two laminate panels.
An article comprising
- a laminate consisting essentially of
- at least one barrier layer comprising expanded PTFE, an adhesive layer, and
- at least one textile layer comprising yarns having a core comprising fiberglass and a sheath comprising modacrylic around said core wherein the textile is bonded to the expanded PTFE by the adhesive layer,
- wherein said laminate has a weight of about 15 oz/yd2 less and is liquidproof after 20,000 flex cycles.
1 more element
An article comprising
- a laminate comprising
- a barrier layer and
- at least one textile layer on each side of the barrier layer, the at least one textile layer comprising yarns having a core comprising fiberglass and a sheath comprising one or more continuous or staple filaments comprising a second material around said core,
- wherein the laminate weighs less than 10 oz/yd2 and wherein the laminate is liquidproof after 10,000 flex cycles.
