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： Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, plasticizers, with the addition of a diacid, diglycidyl ether, silicone and/or a glyceride additive added during gelatinization of the starch and plasticizer, before blending of such starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, polyamides, etc.). Silicones, where added, may alternatively be added after formation of the thermoplastic starch, e.g., as part of a masterbatch, when blending with another polymer. Addition of silicone reduces glycerin migration and smoke generation, particularly when processing such compositions to form nonwovens. Addition of glycerides (e.g., triglycerides) can increase hydrophobicity of the resulting starch-based polymeric material. Addition of the diacid can reduce molecular weight, while diglycidyl ether addition can build such molecular weight back up, resulting in a narrower molecular weight distribution, and improved processability of the resulting starch-based polymeric material, particularly for nonwoven applications.

摘要： Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, one or more plasticizers, and micro or nano particles or fibers, with such particles or fibers being added before gelatinization of the starch. A diacid or acid anhydride may also be included. Such components are added and then gelatinized together, before blending of a resulting starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, or the like). Addition of such nano or micro particles during synthesis of the thermoplastic starch advantageously results in a far more homogenous distribution of such particles or fibers throughout the starch-based material matrix than occurs where addition of similar particles or fibers is attempted after formation of the thermoplastic starch, e.g., when mixing with a partner resin material. Addition of a diacid during synthesis can reduce molecular weight and viscosity, further aiding in achieving substantially uniform distribution.
