摘要： Described are very high molecular weight (e.g., over 2 million, such as 3-20 million g/mol) starch-based materials, and formulations including such, which can be spun in spunbond, melt blown, yarn, or similar processes. Even with such very high molecular weights, the formulations can be processed at commercial line speeds, with spinneret shear viscosities of 1000 sec−1, without onset of melt flow instability. The starch-based material can be blended with one or more thermoplastic materials having higher melt flow index value(s), which serve as a diluent and plasticizer, allowing the very viscous starch-based component to be spun under such conditions. The particular melt flow index characteristics of the thermoplastic diluent material can be selected based on what type of process is being used (e.g., spunbond, melt blown, yarn, etc.). The starch-based material may exhibit high shear sensitivity, strain hardening behavior, and/or very high critical shear stress (e.g., at least 125 kPa).

摘要： The present disclosure relates to a flame-retardant fabric that includes a modacrylic fiber and a cellulose fiber. The cellulose fiber is one or more selected from a regenerated cellulose fiber and a natural cellulose fiber. The flame-retardant fabric contains the modacrylic fiber in an amount of 65 to 90 wt % and the cellulose fiber in an amount of 10 to 35 wt % with respect to the overall weight of the fabric. The modacrylic fiber contains a magnesium compound inside the fiber. The flame-retardant fabric contains the magnesium compound in an amount of 2.5 to 4.5 wt %. Afterflame time and afterglow time of the flame-retardant fabric measured using a flammability test based on ISO 15025: 2000 are 2 seconds or less and 2 seconds or less, respectively.

摘要： 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.

摘要： A method to manufacture composite fibers of rice husk and charcoal includes the following steps. Heat and grind the rice husk and the charcoal and blend with PET to form first granules and second granules respectively wherein mass fractions of rice husk and charcoal are 15-20 wt %. The mass fraction of rice husk in the first granules and that of the charcoal in the second granules are equal. Blend the first granules and the second granules to form mixed granules. Blend and melt the mixed granules and PET to form a mixture wherein the summation of the mass fractions of rice husk and charcoal in the mixture is 0.2-2 wt %. Form composite fibers from the melted mixture by a procedure of filament making.

摘要： Textiles are provided that include fibrous cellulosic materials having an α-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.

摘要： The invention relates to a swiftly breakable and totally degradable non-woven spunlace and its fabrication methods and production line. It is composed of 35-50% zigzagging flat viscose and 65-50% wood pulp. It enjoys the following strengths: excellent breaking performance; total degradation of non-woven fiber upon breaking and avoidance of second environmental protection; great play of material features due to pre-treatment of raw materials and good strength of non-woven cloth under the dry and humid status.

摘要： A method to prepare nonwoven webs which have good MD and CD strength, and are water disposable is provided. The method includes hydroentangling an airlaid web of no less than 50% by weight of natural cellulose fibers having a fiber length of no more than 3.5 mm and no more than 50% by weight staple fibers having a fiber length of no less than 8.0 mm. The airlaid web is not laid on a precursor web and no adhesive, binder or thermal bonding fibers are utilized. The airlayering and hydroentangling are conducted in a continuous operation. Products may be obtained according to the method of this invention that meet municipal guidelines for flushability.
