摘要:
Flame resistant fabrics that have incorporated into them cellulosic filament yarns. The cellulosic filament yarns may be flame resistant (either inherently FR or treated so as to be FR) or non-flame resistant. Fabrics according to some embodiments are formed entirely of cellulosic filament yarns. However, fabrics according to some embodiments include additional yarns to ensure that the fabric complies with NFPA 1971 and/or 2112.
摘要:
A stretch-bonded elastic nonwoven composite includes a machine-direction elastic apertured film-based, stretch-bonded laminate layer that has been hydroentangled throughout all of its laminate layers with a hydrophilic fibrous layer. The elastic apertured film-based, stretch-bonded laminate layer includes a middle elastic film layer positioned between one or two inelastic layers, each of which layers includes hydrophilic fibers from the hydrophilic fibrous layer.
摘要:
Disclosed are technical fibers and yarns made with partially aromatic polyamides and a fiber having vapor phase action such as an FR cellulosic fiber. Fabrics made from such fibers and yarns demonstrate superior flame retardancy over traditional flame retardant nylon 6,6 fabrics. Further, the disclosed fibers and yarns, when blended with other flame retardant fibers, do not demonstrate the dangerous “scaffolding effect” common with flame retardant nylon 6,6 blended fabrics.
摘要:
The invention relates to a method for the manufacture of fibrous yarn comprising the steps, where an aqueous suspension (100) comprising fibers and at least one rheology modifier is provided, followed by directing said suspension (100) through at least one nozzle (20a, 20b, 20c, 30a, 30b, 30c, 40a, 40b, 40c), to form at least one yarn, and then dewatering said yarn.
摘要:
Systems and methods for weaving helical carbon fabrics with minimum fiber crimp are provided herein. In various embodiments, small denier natural or synthetic yarns (202) are used in the warp direction to interlace the carbon fiber wefts (204,208,210) with minimum deformation. Specific weave designs are used in combination with the small denier yarn to maintain the primary carbon fiber weft and warp un-crimped.
摘要:
A cord, in particular for reinforcing tyres, containing a cellulosic multifilament yarn, characterized in that the cellulosic multifilament yarn has a strength of at least 35 cN/tex and the individual filaments of the multifilament yarn have a linear density of at least 2.3 dtex, is disclosed. In use, such cords display a significantly improved fatigue behaviour, i.e. a significantly higher fatigue resistance, than standard cords having a linear density of the individual filaments in the range from 1 to 2 dtex.
摘要:
A fabric, fiber or article comprising a plurality of fiber bodies, the plurality of fiber bodies including a first fiber material and a second fiber material, wherein the first fiber material comprises a cellulosic material and a phase change material dispersed in the cellulosic material, the phase change material forming a plurality of domains dispersed in the cellulosic material, the phase change material having a latent heat of at least 5 Joules per gram and a transition temperature in the range of 0°C to 100°C, the phase change material providing thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature. Wherein the second fiber material comprises a fire resistant material.
