Non-woven flame-retardant material
A thermoformable non-woven material that meets at least one of the UL94 V-0 (2013) flammability standard and the ASTM E84-14 (2014) flammability standard. The material may include charring fiber having a denier per fiber at least about 3 and binding fiber having a denier per fiber between about 1 and about 8. The weight ratio of charring fiber to binding fiber may be between about 2:1 and about 4:1, and the denier per fiber of the charring fiber may be at least about twice the denier per fiber of the binding fiber.
LYOCELL MATERIAL FOR CIGARETTE FILTER AND METHOD FOR PREPARING SAME
Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.
WICKING MATERIALS
Wicking materials are described comprising: a first layer comprising a plurality of cellulose acetate (CA) fibers; and a second layer comprising a plurality of polyvinylpyrrolidone (PVP) fibers. Methods of manufacturing the wicking materials and biosensors comprising the same are also described.
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.
Lyocell material for cigarette filter and method for preparing same
Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.
METHOD FOR MANUFACTURING SHORT FIBERS, METHOD FOR MANUFACTURING NONWOVEN FABRIC, SHORT FIBER MANUFACTURING DEVICE, AND NONWOVEN FABRIC MANUFACTURING DEVICE
A method for manufacturing short fibers includes relaxing entanglement of crimped cellulose acetate fibers in a tow band by applying a tension in a predetermined transfer direction to the tow band transferred in the transfer direction, the tow band containing the crimped cellulose acetate fibers and being impregnated with moisture, and forming short fibers by cutting the tow band in which the entanglement is relaxed.
TEXTILES AND METHODS AND SYSTEMS FOR PRODUCING TEXTILES
Textiles are provided that include fibrous cellulosic materials having an -cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.
POLYMERS, ARTICLES, AND CHEMICALS MADE FROM DENSIFIED TEXTILE DERIVED SYNGAS
Densified textile aggregates are co-fed with a fuel into a partial oxidation gasifier. High solids concentrations in the feedstock composition can be obtained without significant impact on the feedstock composition stability and pumpability. A consistent quality of densified textile derived syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The densified textile derived syngas quality, composition, and throughput are suitable for produce a wide range of chemicals and polymers, including methanol, acetic acid, methyl acetate, acetic anhydride, and cellulose esters through a variety of reaction schemes in which at least a portion of the chemical or polymer originates with densified textile derived syngas.
HIGH POPULATION OF CLOSED C-SHAPED FIBERS
A high population density of closed C shaped cellulose acetate filament can now be reliably produced. The closed C filaments are made from a spinneret having a. substantially D shaped orifice under particular processing conditions depending on the dpf of the filament, the theta angle of the D shaped orifice, and dope temperature. The process can make a high population count of closed C shaped fibers in a. tow band, and article are not provided having the high population density of closed C shaped fibers.
HIGH DPF CELLULOSE ACETATE TOW AND PROCESS FOR MAKING
Disclosed are cellulose acetate cellulose acetate tow and processes for making cellulose acetate tow having at least 15 denier per filament, e.g., at least 20 denier per filament, or at least 25 denier per filament. The cellulose acetate tows may have total denier of more than 20,500.
