A structure of aligned (e.g., radially and/or polygonally aligned) fibers, and systems and methods for producing and using the same. One or more structures provided may be created using an apparatus that includes one or more first electrodes that define an area and/or partially circumscribe an area. For example, a single first electrode may enclose the area, or a plurality of first electrode(s) may be positioned on at least a portion of the perimeter of the area. A second electrode is positioned within the area. Electrodes with rounded (e.g., convex) surfaces may be arranged in an array, and a fibrous structure created using such electrodes may include an array of wells at positions corresponding to the positions of the electrodes.

Among other things, the inventive subject matter generally relates to nonwoven textiles consisting of webs of superfine fibers, i.e., fibers with diameters in nanoscale or micronscale ranges, for use in articles that have, for example a predetermined degree of waterproofness with breathability, or windproofness with breathability.

Disclosed is a spunbond nonwoven fabric comprising a purity of continuous bicomponent fibers having a sheath/core configuration, wherein ionomer of ethylene/(meth) acrylic acid copolymer forms the sheath and polyamide forms the core. Also disclosed herein is a nonwoven composite made thereof.

The present disclosure relates to a method for preparing a non-woven fabric which improves impregnation and release properties of a fabric softener in the non-woven fabric in order to apply the non-woven fabric to a dryer sheet (sheet-type fabric softener). When increasing porosity and specific surface area in a non-woven fabric made of two-component blended polyester long fibers, impregnation and release rate of a fabric softener are improved even when the non-woven fabric is lightened, making it possible to apply the non-woven fabric to a dryer sheet.

A nonwoven loop material comprising a crimped bi-component fiber in a side-by-side arrangement with a first side and a second side, wherein the first side has a heat of fusion from about 99 to about 105 (J/g) and the second side has a heat of fusion from about 73 to about 86 (J/g); and wherein the first side has a first viscosity and the second side has a second viscosity and the first and second viscosities are within +/−5 (g/10 minutes) of each other; and the second side comprises a polyolefin and a low crystallinity additive.

A production method and production apparatus are provided for nanofiber aggregates produced and stretched into a fine-diameter fibrous shape by spraying a high-temperature, high-pressure gas from gas discharge ports into a polymer solution discharged from a solution discharge port. The nanofiber aggregates are collected into fine-diameter fibers in a high-temperature, high-pressure gas wind force by discharging secondary high-pressure air from high-pressure air blowing discharge ports in an intersecting pattern into a nanofiber flow during production and stretching. Further provided, as an effect, are nanofiber aggregates: having the characteristic that the distribution of fiber diameters thicker than the central fiber diameter and the distribution of fiber diameters thinner than the central fiber diameter are equal or better; and having excellent oil absorption capacity and oil keeping capacity.
