Abstract:
A fabric article that generates heat upon application of electrical power is formed, for example, by joining stitch and loop yarns to form a fabric body, with the loop yarn overlaying the stitch yarn at a technical face and forming loops at a technical back of the fabric body. An electrical resistance heating element, e.g., in the form of a conductive yarn, is incorporated into the fabric body at symmetrical and/or asymmetrical spaced-apart intervals as the stitch yarn, the electrical resistance heating elements extending between opposite edge regions of the fabric and conductor elements, e.g. located along edge regions, connect the electrical resistance heating elements to a source of electrical power. The technical face and/or the technical back of the fabric body may have fleece formed by finishing in a manner to avoid damage to electrical conductance of the electrical resistance heating elements. Preferably, the conductive yarn has a core of insulating material, an electrical resistance-heating element about the core, and a sheath material surrounding the electrical resistance heating element and core.
Abstract:
A fabric article that generates heat upon application of electrical power is formed, for example, by knitting or weaving, to form a fabric prebody. An electrical resistance heating element in the form of a conductive yarn is incorporated into the fabric prebody, the electrical resistance heating elements extending between opposite edge regions of the fabric. Conductive elements are provided for connecting the electrical resistance heating elements to a source of electrical power.
Abstract:
A three-dimensional knit or woven fabric that is permeable to water vapor but impermeable to liquid water is provided. The fabric includes a first fabric layer, a second fabric layer and a yarn interconnecting the two layers. The two layers and the yarn are preferably made from a synthetic, such as a polyester or nylon. Both the first and second fabric layers have a barrier layer adhered to the outside surfaces thereof which is both impermeable to liquid water and permeable to water vapor. The fabric is imperviously sealed to prevent the infiltration of water.
Abstract:
A stretchable, drapable, windproof, water resistant and water vapor permeable composite fabric including an inner layer of fabric, a first adhesive layer, a non-porous hydrophilic barrier layer, a second adhesive layer and an outer layer of fabric. At least one of the adhesive layers is of a hydrophilic material and may be continuous, and which joins the inner fabric layer to one side of the barrier layer, the second adhesive layer adhering the barrier layer to the outer fabric layer. The adhesive layers and the barrier layer are constructed to allow water vapor molecules to travel therethrough by a process of absorption-diffusion-desorption, but restrict the passage of wind and liquid water. The inner layer is formed of a hydrophobic material rendered sufficiently hydrophilic to permit wicking or formed with an inner surface formed of said material and an outer surface formed of a naturally absorbent material.
Abstract:
A composite velour fabric garment includes a laminate consisting of an outer woven shell layer, an inner thermal layer of knit construction, and an intermediate layer disposed between and laminated to each of the shell layer and the thermal layer. The outer woven shell layer contains spandex in at least a weft direction for stretch and recovery in a width direction. The knit construction of the inner thermal layer provides stretch in at least a width direction, in harmony with the shell layer, and the inner thermal layer has a raised surface facing inwardly, away from the shell layer. The intermediate layer has controlled air permeability, including zero air permeability.
Abstract:
A textile fabric includes a smooth surface with one or more regions having coating material exhibiting thermal expansion or contraction in response to change in temperature, adjusting insulation performance of the textile fabric in response to ambient conditions.
Abstract:
A flame resistant fiber blend includes a plurality of modacrylic flame resistant fibers comprising a first weight percentage of the fiber blend; a plurality of non-flame resistant hydrophilic/absorbent fibers comprising a second weight percentage of the fiber blend, wherein the second weight percentage is greater than the first weight percentage; and a plurality of second flame resistant fibers comprising a third weight percentage of the fiber blend. In one implementation, the fiber blend includes 20 wt % to 45 wt % of modacrylic flame resistant fibers; 40 wt % to 75 wt % of hydrophilic/absorbent fibers; and 5 wt % to 30 wt % of second flame resistant fibers. The flame resistant fiber blend is used to form flame resistant yarns, fabrics, and garments formed thereof.
Abstract:
Among other things, the disclosure features a thermal blanket including a unitary fabric element having predetermined discrete regions of contrasting insulative capacities arranged based on insulative needs of corresponding regions of a user's body. At least two of the predetermined, discrete regions of contrasting insulative capacities, in one or more first discrete regions of the unitary fabric element, consisting of loop yarn having a first pile height, and in one or more other discrete regions of the unitary fabric element, consist of loop yarn having another pile height different from and relatively greater than the first pile height.
Abstract:
A fabric article includes a fabric body having a technical face and a technical back. The fabric body has a raised surface that is formed at one or both of the technical face and the technical back. The raised surface is formed of yarn comprising polyolefin fibers. In some cases, the polyolefin fibers have a delta or trilobal cross-section. The fibers may be hollow. In certain examples, the polyolefin fibers are formed of a polyolefin and a clarifier.
Abstract:
An under body armor hybrid fabric garment has first and second fabric portions. The first fabric portion, configured to cover an upper torso region of a user's body left exposed by the body armor and extending into a second body transition region covered by the body armor, is formed of low stretch or no stretch fabric of woven or knit construction. The first fabric portion comprises yarns and/or fibers having flame retardant properties. The second fabric element, configured to cover a lower torso region of the user's body underneath the body armor, is formed of stretchable fabric. The second fabric portion comprises yarns and/or fibers having flame retardant properties and/or yarns and/or fibers resistant to melting and dripping when exposed to fire or high heat.
