摘要:
“The invention relates to a method and system for manufacturing a fibrous yarn. An aqueous suspension having fibers and at least one rheology modifier is directed through at least one nozzle to form at least one fibrous yarn. The said nozzle is adapted to swirl the flow of the aqueous suspension around the main flow axis of the said nozzle. Then the aqueous suspension at the exit of the nozzle is merged with at least one annular flow comprising at least one cross linking reagent. Then the fibrous yarn is subjected to pressing mechanism. The pressing mechanism is adapted to dewater and twist the fibrous yarn. Finally, a fibrous yarn product having improved physical properties is produced.”

A hybrid yarn and a fabric including the hybrid yarn are provided. The hybrid yarn is formed of a plurality of fibers of a plurality of different fiber compositions. The different fiber compositions are interspersed throughout the yarn. The yarn may be formed using fibers made of the same material or a plurality of different materials. The different fiber compositions may include fibers of three or more different cross sections, fibers made of different materials or a combination of the two. The materials may be synthetic and/or natural materials. The yarn may be constructed to impart selectable functional characteristics to a fabric without the need to include chemicals to impart those characteristics. Fabrics made with the hybrid yarn will have selectable functional features and also be of lighter weight than previously possible. Hybrid spinnerets may be used to produce hybrid yarns with three or more different fiber cross sections.

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.

A sun control textile with high transmittance and a manufacturing method thereof. In the manufacturing method of the sun control textile (1), a high-performance sun control film (11) is processed into slender filaments (115). The slender filaments (115) are woven and assembled with other yarns by a weaving device to together form a sun control textile (1). The different connection manners of the sun control film yarns (110) lead to different visible light transmittance and sun control effect of the sun control textile (1), whereby an excellent sun control textile (1) with high transmittance can be achieved.

Provided is a flat fiber-reinforced plastic strand which is produced by curing a twisted resin-impregnated strand and has no disturbed fiber orientation, and a flat fiber-reinforced plastic strand sheet which is produced by using said flat fiber-reinforced plastic strands. According to a method of manufacturing the flat fiber-reinforced plastic strand 2, (a) a twisted resin-impregnated strand f2 in an uncured state, the strand including a plurality of reinforcing fibers f, is fed in a state of tension between a pair of heated steel belts 41 A and 41B facing each other and making rotation movements; and (b) the resin-impregnated strand f2 is sandwiched and heated by the steel belts 41A and 41 B, and pressurized from both sides of the strand f2 to form a cross section of the strand into a flat shape, and, with the shape being kept, a resin is cured and cooled.
