摘要： Fabrics containing hydrophilic expanded polytetrafluoroethylene (ePTFE) fibers and at least one non-ePTFE fiber are provided. The fabric provides a combination of high breathability and controlled moisture management. In exemplary embodiments, the fabric may be a woven, knit, or fleece fabric. The fabrics contain at least 15% ePTFE fibers based on the final fabric. The hydrophilic ePTFE fibers in the fabrics may be used to control moisture such as water vapor, liquid water, or sweat within the fabric by storing the moisture within the hydrophilic ePTFE fiber network. Also, little to none of the moisture remains on the outside of the hydrophilic ePTFE fibers, making the fabric feel dry even where there is moisture therein. A polymer membrane and/or a textile may be laminated to the fabric to produce a laminated article.

摘要： Fibers that are formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density are provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. Fibers are thereafter formed and then stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”).

摘要： A multi-component fiber including at least first and second components. In some cases, at least a portion of the first component is opaque and microporous, and the second component is different from the first component. In some cases, at least a portion of the second component can be seen through at least a portion of the first component. A fiber having an opaque, microporous region and a see-through region of lower porosity is also disclosed. Fibrous webs including such fibers are also disclosed. In some cases, the fibrous web has at least one first region where first portions of the multiple fibers are opaque and microporous and at least one second region where second portions of the multiple fibers form a see-through region of lower porosity. Articles and laminates including the fibrous webs are disclosed. Methods of making the fibers, fibrous webs, and articles are also disclosed.

摘要： A method of attaching a molecule-of-interest to a microtube, by co-electrospinning two polymeric solutions through co-axial capillaries, wherein a first polymeric solution of the two polymeric solutions is for forming a shell of the microtube and a second polymeric solution of the two polymeric solutions is for forming a coat over an internal surface of the shell, the first polymeric solution is selected solidifying faster than the second polymeric solution and a solvent of the second polymeric solution is selected incapable of dissolving the first polymeric solution and the second polymeric solution comprises the molecule-of-interest, thereby attaching the molecule-of-interest to the microtube. An electrospun microtube comprising an electrospun shell, an electrospun coat over an internal surface of the shell and a molecule-of-interest attached to the microtube.

摘要： Hollow fiber membranes having improved toughness and durability are prepared using a vinylidene fluoride polymer-containing component, such as Kynaro resins, having relatively low crystallinity. One aspect of the invention provides a membrane in the form of a fiber, wherein i) the fiber has a porous wall of a polymeric component enclosing a central hollow space extending the length of the fiber, ii) the polymeric component has a crystallinity as determined by wide angle x-ray diffraction of less than about 35%, iii) the polymeric component is comprised of at least one homopolymer or copolymer of vinylidene fluoride and iv) the membrane has an energy to break of at least about 0.5 J per square mm of membrane cross section.
