Self-crimping fully drawn high bulk yarns comprising fiber forming bicomponent filaments comprising two polymers having different crystallizability or differential orientation or combination thereof is disclosed herein. Further the present invention discloses a method for producing the self-crimping fully drawn high bulk yarns by single and two-stage process. The invention also discloses the fabric comprising the self-crimping fully drawn high bulk yarns.
摘要:
A crystalline nano wire material which can be used as a nano-level wire is provided.A molecular monocrystal having a high anisotropy for electrical resistivity is used.
摘要:
This invention provides a hydrophilic porous fiber wick for delivering vaporizable material into the atmosphere, such as a room environment. The wick may be biodegradable. The wick is comprised of a sintered synthetic bicomponent fibers, optionally combined with synthetic monocomponent fibers or natural monocomponent fibers. The wick is optionally treated with plasma or finishing agents for improved hydrophilicity. The wick can wick aqueous and/or non-aqueous-based fragrances or other vaporizable materials and evaporate them into the air without the use of heat, convection air, or atomization.
摘要:
A surface-finished yarn having multiple inorganic materials is provided. The surface-finished yarn comprises a yarn, a first material and a second material. The surface of the yarn comprises a plurality of the plurality of first regions and a plurality of second regions wherein the plurality of first regions and the plurality of second regions are alternately disposed along an axial direction of the yarn. The first material is disposed onto the plurality of first regions while the second material different from the first material is disposed onto the plurality of second regions.
摘要:
A flock material exhibiting an increased degree of filament separation prepared by cutting a fluoropolymer or carbon fiber yarn into lengths, introducing mechanical energy into the lengths in order to cause the lengths to separate into single-filaments fibers and removing or classifying at least a portion of the single-filament fibers from the lengths in order to obtain a flock having a particular fraction of single-filament, fluoropolymer or carbon fibers.
摘要:
In accordance with the invention, there are image forming apparatuses, fuser members, and methods of making fuser members. The fuser member can include a substrate and an electrospun layer disposed over the substrate, the electrospun layer including a structure selected from a group consisting of a fiber-on-fiber structure, a bead-on-fiber structure, and a pop-corn structure, wherein the fuser member includes a top surface that is both hydrophobic and oleophobic.
摘要:
A fabricated microstructure includes a substrate, a primary fiber, and a plurality of base fibers. The primary fiber has a width less than about 5 microns. Each base fiber of the plurality of base fibers has a first end attached to the primary fiber and a second end attached to the substrate. Each base fiber has a width less than the width of the primary fiber.
