Flame Resistant Fabrics for Protection Against Molten Metal Splash
Embodiments of the present invention relate to flame resistant fabrics that provide protection against molten metal splash but that have improved comfort at a lower cost by predominantly locating the protective molten metal shedding fibers on the front face of the fabric. Concentrating the protective fibers predominantly on the front face of the fabric still provides good protection against molten metal adherence and allows for more comfortable (and less expensive) fibers to be used on the back face of the fabric positioned next to the wearer. In this way, overall protection of the fabric is maintained while improving comfort. Embodiments of such fabrics may also achieve NFPA 70E PPE Category 2 protection (?8 cal/cm.sup.2 arc rating whether ATPV or EBT).
SYSTEM AND METHOD FOR TEXTILE POSITIONING
In various embodiments, the present disclosure relates generally to a method for needling a spiral textile to create a needled preform, the method comprising receiving the spiral textile on a bed plate of a circular needle loom, engaging a positional structure of the spiral textile, rotating the spiral textile around the circular needle loom, depositing a predetermined number of layers of the spiral textile on the bed plate, and needling the spiral textile to create the needled preform. Moreover, the present disclosure also provides, in various embodiments, a method for creating a circular needled preform from a spiral textile, comprising attaching sacrificial fibers to at least one of the weft tow and the plurality of warp tows proximate at least one of the inside diameter and the outside diameter, and engaging the sacrificial fibers with an engagement mechanism on a circular needle loom.
Protective woven fabric and process for producing same
A protective woven fabric of the present invention includes super fiber yarns. The warp of the woven fabric is a covered yarn (1, 4, 5) composed of two or more twisted inorganic filament yarns as core yarns (2a, 2b) and one or more super fiber yarns (3, 3a, 3b, 3c) as covering yarns that are wound and twisted around the core yarns (2a, 2b), and a weft thereof is a super fiber yarn. Preferably, the covered yarn is a W covered yarn in which a twist coefficient K of the covering yarns with respect to the core yarns is 2000 to 30000. Due to this, it is possible to provide a protective woven fabric that, even when the warp and the weft is squeezed or rubbed by the reed, heddles, etc., of a loom, has few defects such as fluff or fiber aggregates and which has a satisfactory weaving pattern while retaining a high protective function. A force required to cut this woven fabric is 50 N or more, preferably 60 N or more, as measured through a cutting test in accordance with JIS-T8052, even when the fabric is a monolayer woven fabric.
Core-spun yarn featuring a blended core for use in the construction of flame barrier fabrics and finished articles made therefrom
A fire resistant core-spun yarn that comprises a unitary core having a blend of a filament fiber and non-filament fibers, and a sheath containing one or more staple fibers that substantially encapsulates the unitary core; and flame barrier substrates and articles made therefrom.
Methods and compositions for cooling yarns and fabrics, and articles comprising same
In one aspect, the disclosure relates to composite yarns having a structure comprising a core component and sheath layer, wherein each of the core component and the sheath layer independently comprise a polymer and a disclosed cooling composition. In various further aspects, the present disclosure pertains to double covered yarns comprising an elastic core comprising an elastic core; a first yarn in contact with the elastic core, and wherein the first yarn comprises a disclosed yarn comprising a core component and a sheath layer; and a second yarn in contact with the first yarn, and wherein the second yarn comprises a yarn comprising a cellulosic fiber. In still further aspects, the present disclosure pertains to a fabric, such as a denim fabric. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
Flame resistant fabric with anisotropic properties
Flame resistant fabrics are formed by warp and fill yarns having different fiber contents. The fabrics are constructed, for example, by selection of a suitable weaving pattern, such that the body side of the fabric and the face side of the fabric have different properties. The fabrics described herein can be printable and dyeable on both sides of the fabric and are suitable for use in military and industrial garments. Methods of forming flame resistant fabrics, and methods for forming garments from the fabrics, are also described.
FLAME-RETARDANT FABRIC HAVING HIGH VISIBILITY
Provided is a flame-retardant fabric having a color that satisfies the criteria required by the international standard for high visibility ISO20471. The fabric includes polyetherimide-based fibers that contain a white pigment.
GLASS CLOTH
A glass cloth includes warp yarns and weft yarns formed by bundling in the range of 14 to 55 glass filaments having a diameter in the range of 3.0 to 4.2 m, and has a weaving density of the warp yarns and the weft yarns of 86 to 140 yarns/25 mm, a thickness of 7.5 to 12.0 m, a mass of 6.0 to 10.0 g per m.sup.2, and an average number of stages of 2.00 or more and less than 3.00, an average degree of opening, which is indicated as the geometric mean of the degree of opening of the warp yarns and the degree of opening of the weft yarns, in the range of 1.000 to 1.300, and a yarn width ratio, as the ratio of the yarn width of the warp yarns to that of the weft yarns, in the range of 0.720 to 0.960.
GLASS COMPOSITION, GLASS FIBERS, GLASS CLOTH, AND METHOD FOR PRODUCING GLASS FIBERS
A glass composition of the present disclosure includes, in wt %, 50SiO.sub.254, 25B.sub.2O.sub.330, 12Al.sub.2O.sub.315, 0.5MgO1.9, 3.0CaO5.5, 0ZnO3.5, 0.1Li.sub.2O0.5, and 0.1Na.sub.2O0.3, and has a permittivity of less than 5.0 at a frequency of 1 MHz. The glass composition of the present disclosure has a low permittivity. The use of this glass composition can reduce the occurrence of devitrification and the inclusion of bubbles in glass fibers to be formed or in a shaped glass material to be formed even when the glass fibers have a small fiber diameter or the shaped glass material has a small thickness.
ARTICLE PROVIDED WITH WARNING SYSTEM
The problem to be solved is to provide an article that is capable of detecting position information within a building, and detecting hazards related to life such as heat stroke to issue an alarm, while ensuring safety, workability, and convenience. Means to solve the problem is an article including an alarm system, wherein the alarm system includes, a position information sensor, a three-axes acceleration sensor, a gyro sensor, a geomagnetic sensor, or a combination thereof; and a part configured to autonomously estimate a position from information emitted from the position information sensor, etc.
