摘要： Fibers of diverse materials find widespread use in inorganic binder compositions to improve the properties of the final cured composite materials. When using high amounts of fiber in inorganic binder slurries, problems arise due to the loss of workability because of unevenly distributed fiber content. The novel fibers according to the invention allow the use of large amounts of fiber without loss of workability and are particularly useful to control the rheology of the composite slurry mixtures.

摘要： A multiphasic microfiber for a three-dimensional tissue scaffold and/or cellular support is provided in one aspect that includes at least one biocompatible material. The multiphasic microfiber optionally has a first phase and at least one distinct additional phase and is formed by electrohydrodynamic jetting. Further, such microfibers optionally have one or more biofunctional agents, which may be surface-bound moieties provided in spatial patterns. Multiphasic microfibers formed in accordance with the disclosure may form, in some cases, three-dimensional fiber scaffolds with precisely engineered, micrometer-scaled patterns for cellular contact guidance, which may thus support and/or promote cellular growth, proliferation, differentiation, repair, and/or regeneration for tissue and bioengineering applications.

摘要： Apparatus and method for forming nanofibers and nonwoven webs formed of such nanofibers. The nanofibers are formed by changing the rheology in at least first and second flows of a liquid material such that the changed rheology of the first and second flows differs by an amount sufficient to produce a phase separation when the first and second flows are combined to define meltblown fibers. Each meltblown fiber has lengthwise first and second cross-sectional regions formed of the liquid material from the first and second flows, respectively. These regions are separated along a length of at least a majority of the meltblown fibers to form a plurality of nanofibers, which are collected together with any unsplit meltblown fibers to form the nonwoven web. The difference in the changed rheology of the flows may be produced by using two extruders with different barrel diameters to create differ shear histories for the two flows.

摘要： A textile fabric has at least one raised surface incorporating multicomponent fibers formed of at least a first material and a second material disposed in side-by-side relationship. The first material and the second material exhibit differential thermal elongation, which causes the multicomponent fibers to bend or curl and reversibly recover in response to changes in temperature, thereby adjusting insulation performance of the textile fabric in response to ambient conditions.
